Explanation:
It's embryonic cells. Embryonic stem cells (ESCs) are stem cells derived from the undifferentiated inner mass cells of a human embryo. Embryonic stem cells are pluripotent, meaning they are able to grow (i.e. differentiate) into all derivatives of the three primary germ layers: ectoderm, endoderm and mesoderm.

Tina-Marie accidentally left her water bottle outside on a freezing, winter night. The next day, the water bottle, which is now filled with ice, ruptured. Based on her observations, Tina-Marie forms a hypothesis about freezing water and volume. Identify a hypothesis Tina-Marie can investigate. Then describe an experimental procedure for investigating the hypothesis.
Answer:
Hypothesis, Ice is less dense then water.
Explanation:
They could test this by attaining the density of ice and water, the density of Water is 1g/ml and if the ice floats that means ice is less then 1 g/ml which means ice is less dense. This is relevant to the water bottle because the Ice expanded due to it being less dense causing the water bottle to rupture
Which organelle would be more developed in a cell of salivary glands?
Answer:
Lysosomes
Explanation:
Salivary glands are secretory cells, meaning they release substances into the extracellular environment. In the case of the salivary glands, they secrete water, electrolytes, mucus and enzymes, the components of saliva. Therefore, these cells have a very well-developed secretory system.
Lysosomes store secretory proteins and are important for keeping them sequestered from the rest of the cell, and eventually delivering them outside the cell.
Some students want to test different soils to find out which ones absorb heat the fastest. For the first test, they put 500 grams of sand in a beaker and put a thermometer in the sand. Which aspect of this experiment should be kept the same in all the other tests? Some students want to test different soils to find out which ones absorb heat the fastest. For the first test, they put 500 grams of sand in a beaker and put a thermometer in the sand. Which aspect of this experiment should be kept the same in all the other tests?
Answer:
Weight of the soil (500g)
Explanation:
According to this question, some students are conducting an experiment in order to find out which of the different soils used absorb heat the fastest. For the first test, they put 500 grams of SAND in a beaker and put a thermometer in the sand.
In an experiment, the variables that must be kept constant for all the groups is called the CONSTANT OR CONTROLLED VARIABLE. This is done in order not to influence the outcome of the experiment. In this case, the weight (500g) of the soil should be kept the same for all other tests.
This means that for the remaining soil being tested, 500g of each type of soil should be used.

Explanation:
Analiza las siguientes situaciones.Luego indica que parte del sistema nervioso esta actuando en cada una. Explica por que 1) estás frente a un profesor dando examen oral sobre un tema que no estudiaste mucho. Estas nervioso y un poco pálido a medida que surgen las preguntas, te tiemblan y te sudan las manos. Antes de empezar el examen tenias ganas de ir al baño, pero se te fueron...
Respuesta:
1) Sistema Nervioso Simpático.
2) Primero, Sistema Nervioso Parasimpático. Luego, Sistema Nervioso Simpático.
3) Sistema Nervioso Parasimpático.
Explicación:
La pregunta está incompleta, falta la siguiente parte:
2) Estás durmiendo luego de una abundante cena, de pronto, sentís unos golpes tremendos, te tiran la puerta abajo y unos encapuchados te apuntan con algo que parece un arma ¡chau digestión! Sentís que los músculos se ponen cada vez más tensos.
3) Tus amigos te jugaron una broma pesada. ¡Los querés matar! Sentís que poco a poco tus pulsaciones vuelven al ritmo normal ¡Qué día!
Respuesta:
El sistema nervioso es un conjunto de células que controlan todas las funciones del cuerpo, incluyendo órganos y músculos. Para llevar a cabo dichas funciones, el sistema nervioso se encuentra dividido en dos grandes partes:
Sistema Nervioso Central (SNC): Conformado por el cerebro y médula espinal, que procesa la información recibida para mandar instrucciones al cuerpo sobre que funciones realizar.Sistema Nervioso Periférico (SNP): Conformado por nervios que se extienden desde la médula espinal hacia todo el cuerpo y son las responsable de captar señales que envían al cerebro.El SNP, se divide entonces en Sistema Nervioso Somático, el cual conecta al SNC con todos los músculos para modular sus movimientos voluntarios e involuntarios y transmite la información desde el exterior hacia el interior. Y también se divide en Sistema Nervioso Autónomo (SNA) el cual a su vez presenta otras dos ramificaciones:
Sistema Nervioso Simpático: Controla respuestas que activan funciones y preparan al cuerpo para responder a situaciones diversas de estrés y peligro.Sistema Nervioso Parasimpático: Tiene una acción opuesta, para retornar al organismo a un estado de equilibrio.Por lo tanto, el SNA se encuentra en la periferia y desde el cerebro salen nervios hacia todo el cuerpo, llamados fibras eferentes, enviando información de las vísceras y algunos órganos para controlar sus funciones de acuerdo a los estímulos percibidos. Por lo tanto, esta división del sistema nervioso controla movimientos involuntarios como la digestión, presión sanguínea, reflejos involuntarios, etc.
Por ejemplo, frente a una situación de estrés o de peligro, el Sistema Nervioso Simpático hace que el cuerpo entre en un estado de alerta para así estar preparado para defenderse y/o huir. Entonces, se envían señales a glándulas y músculos para que lleven a cabo ciertas funciones como dilatar pupilas, liberar adrenalina, inhibir la digestión, aumentar la presión sanguínea, etc. Todo esto ayuda al cuerpo a utilizar las energías disponibles para huir o defenderse frente al peligro y no malgasta las energías en funciones que no son prioridad en ese momento (como la digestión, entre otras) Cuando la situación se termina y la persona se tranquiliza, el Sistema Nervioso Parasimpático retorna al organismo hacia un estado de equilibrio causando la constricción de pupilas, liberando acetilcolina estabilizando la presión, retomando la digestión, etc. De esta manera, el organismo continua llevando a cabo sus funciones normales.
1) En este caso, la persona se encuentra muy nerviosa por estar siendo evaluada por un profesor y frente a toda la clase. Entonces, el Sistema Nervioso Simpático hace que la sangre se dirija a los músculos y el cuerpo se prepara para "huir" dejando de lado otras situaciones como ir al baño. La sudoración tiene la función de bajar la temperatura corporal, y los temblores vienen por parte de las palpitaciones y la presión sanguínea alta.
2) Mientras la persona duerme y hace la digestión, actúa el Sistema Nervioso Parasimpático, ya que el cuerpo se encuentra tranquilo y en resposo, sin situaciones estresantes o de peligro y puede funcionar de forma normal como siempre. Pero en el momento en el que la persona escucha ruidos, se despierta de golpe y al ver gente extraña la persona se pone nerviosa, se inhibe la digestión y otras funciones no primordiales para la supervivencia y la persona se encuentra en estado de alerta. En este caso, actúa el Sistema Nervioso Simpático. También se tensan los músculos, preparándose para ser usados y escapar.
3) Cuando la persona se da cuenta que los encapuchados eran amigos y solo era una broma, se calma, y baja el ritmo cardíaco por lo que actúa el Sistema Nervioso Parasimpático. La persona ya no necesita estar en estado de alerta para escaparse y huir.
Why do the plant and animal cells SHARE some levels of classification?
Why are some levels of classification DIFFERENT?
Answer:
All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups. These smaller groups are based on more detailed similarities within each larger group. This grouping system makes it easier for scientists to study certain groups of organisms. Characteristics such as appearance, reproduction, mobility, and functionality are just a few ways in which living organisms are grouped together. These specialized groups are collectively called the classification of living things. The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species .

The starting materials of cellular respiration are energy, carbon dioxide, and water?
Answer:
[tex]\boxed {\tt False}[/tex]
Explanation:
Cellular respiration is a process that creates energy. The equation is:
[tex]C_6H_{12}O_6+6O_2 ->6CO_2+6H_2O+38 \ ATP[/tex]
The reactants, or starting materials are: glucose and oxygen.
The products, or ending materials/results are: carbon dioxide, water, and energy.
Therefore, the statement in the question is false. Energy, carbon dioxide, and water are the ending materials, not the starting ones.

If the DNA sequence was a AGC what would the mRNA sequence be?
Answer:
DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using 'T' as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'.

Explain whether the top or bottom layers would be the oldest layer of sedimentary rock.
explain your answer.
Answer:
Because sedimentary rock forms in layers, the oldest layer of undisturbed sedimentary rock will be on the bottom and the youngest on top. If the rock layers are bent, they may no longer be in order from oldest to youngest.
The bottom layer would be the oldest layer of sedimentary rock as sediments deposited earlier will be present at the bottom.
What are sedimentary rocks?They are the types of rocks which are formed as a result of accumulation of minerals or organic particles at the surface of the earth.Sedimentation is the name given to a collective process which cause the particles to settle.
The study of sedimentary rocks is useful in civil engineering and as important sources of coal, fossil fuels and ores.The color of sedimentary rock is often determined by iron content and sometimes due to the presence of organic matter.
They are classified based on origin in to 4 types which are clastic, biochemical ,chemical and other sedimentary rocks.While based on composition they are classified as siliciclastic,carbonate ,evaporite,organic rich,siliceous ,iron-rich and phosphatic sedimentary rocks.

What are the questions?
Explanation:
1. The______ provides support and rigidity to cells allowing plants to stand upright.
plz help I need an answer
sclerenchyma
Explanation:
sclerenchyma is a suppprting tissue that gives the plants rigidity and support to make it stand upright. It is made up of scleroids and fibre.
Scleroids are small stonelike materials that are arranged in a way that helps the plants withstand force.
For example when rain falls and the wind's current is strong, it sways the plant from left to right but because of sclerenchyma, the plant can withstand the current and return to its normal position. But if the winds current or force is stroonger than that of the sclenchyma, the plant bends or breaks
1.Water covers 70 percent of the earth's surface and supports life on the Earth. Explain the statement 2.Why do we need to manage our resources? { i need the answer before 4 pm please help!}
Explanation:
Water is extremely valuable to all living things. It is especially important for plants to perform photosynthesis which is one of the smallest most valuable biochemical mechanisms known to life, in addition, plants are the main source of nutrients for many creatures. Without photosynthesis, plants would not be able to produce oxygen. In addition, plants are classified as producers, the most basic level of the flow of energy in every ecosystem and are the main reason energy from the sun can then be converted into usable energy for primary consumers, secondary consumers, and tertiary consumers. For humans, water is extremely important to keeping our bodies in homeostasis while the billions of chemical reactions take place in our bodies in just minutes. A human can not live without water for more than three to four days. If there was a deficiency of water both plants, animals, and humans would be greatly affected. Without water, plants would not grow, so no conversion CO2 to 02 and harnessing energy from the sun. Next animals that depend on both water and plants would have a decrease in population. Followed by the depletion of all else consumers. You remove a resource this valuable and there is no coming back.

What is the blending theory of inheritance? Why did Mendel question this theory?
Answer:
Blending Theory of Inheritance
Mendel noticed plants in his own garden that weren't a blend of the parents. For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height. Observations such as these led Mendel to question the blending theory
The blending theory state that the inheritance of traits from two parents produces offspring with characteristics that are combination of the parents.
What is blending theory of inheritance?Blending theory of inheritance stated that, offspring is combination of characteristics of the traits from two parents. Blending inheritance was discarded after the general acceptance of the modern genetics.
Mendel noticed that plant in his garden were not blend of the parents. For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height.
Therefore, Mendel question this theory. He wanted to know if there was different principle that could explain how the characteristics are inherited to the offspring from parents.
