Explain why it is very important for the gametes to divide by meiosis. What could happen if the gametes accidentally divide by mitosis? can someone answer in a sentence!!
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
Explanation: Gametes are made via meiosis which produces cells with n=23 instead of diploid cells. If gametes were produced instead by mitosis each gamete would be diploid not haploid.

The appendix, an extension of the large intestine appears, although this is debated, to have little
function in humans. What is the appendix an example of in terms of evidence for evolution?
Answer: Vestigial organ
Explanation:
Vestigial organs are those organs which were functional in ancestral organisms belonging to the same species but due to the course of evolution of body forms they become non-functional. They can be found in the body either in the same form as used to appear in the ancestors or in rudimentary or degenerated forms.
The human appendix is one of the examples of vestigial organs. It looks like a narrow tube which forms a link with a colon of the large intestine. It was functional in human herbivorous ancestors as it used to help in digestion of variety of vegetables and other plant products. The change of diet along with due course of evolution caused the appendix to become useless. But the appendix physical form remained the same in humans.

Young hermit crabs pick up sea anemones which live on their shells. The stingy tentacles of the anemone keep fish from eating the hermit crab, and the sea anemone is able to eat leftover food from the hermit
crab. Which best describes the relationship between the sea anemone and the hermit crab?
A commensalism
B. O mutualism
c. parasitism
DO predation
Answer:
mutualism.
Explanation:
Mutualism can be defined as an symbiotic relationship or interaction between two or more living organisms of different species that typically involves each organism benefiting positively. Therefore, mutualism influences the survival and reproduction of living organisms in their habitats.
In this scenario, young hermit crabs pick up sea anemones which live on their shells. The stingy tentacles of the anemone keep fish from eating the hermit crab, and the sea anemone is able to eat leftover food from the hermit crab. Therefore, the relationship between the sea anemone and the hermit crab is best described as mutualism because both of them are benefiting from the interaction.
Simply stated, the sea anemone provides protection (security) from predators for the hermit crab while the hermit crab provides food for the sea anemone.
Which generalization can be made from the data in the table?
1.The higher the temperature, the fewer chirps there will be in 10 seconds.
2.The chirps occur closer together as the temperature increases.
3.The chirps become farther apart as the temperature increases.
4.There is no relationship between temperature and the time between chirps.
The generalization that can be made is: 2.The chirps occur closer together as the temperature increases.
Generalization is a statement you state after making an inference from an observation. For example, we can make a generalization by observing or analyzing the data from the experiment conducted which are given in the table.
From the table given, there seems to be a trend that can be observed. Temperature seems to influence the number of seconds between each chirp of the cricket.
A closer observation of the trend from the data given shows that in general, as the temperature was increased, the seconds between chirps seem to shorten.
Therefore, we make a generalization stating that: "2.The chirps occur closer together as the temperature increases."

How is the brain involved with the senses and what is the relationship to the wat a personreacts to objects?
Answer:
The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. All sensations are electrical signals that travel through neurons which form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis.
Explanation:
The brain is an organ that controls the activity of the body, both its conscious and unconscious functions. It is located in the head and corresponds, therefore, to the encephalon of humans and other vertebrates and is subdivided into forebrain, midbrain and hindbrain.
The brain acts on the rest of the organism by generating muscle activity or by the production and secretion of chemicals called hormones. Thereby the brain controls responses to changes in the environment. Some basic types of response such as reflexes may be mediated by the spinal cord or peripheral ganglia, but sophisticated intentional control of behavior based on complex sensory information requires the integration of information.
The thalamus, which is located in the central part of the brain, processes and coordinates the messages from the senses that it receives from the body. Five senses are considered to exist: sight, touch, smell, taste and hearing. For that, the information perceived from the outside must reach the brain.
The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. Therefore, all sensations perceived from the outside are electrical signals that travel through neurons. For example, the eyes transform light signals into electrical impulses, which travel to the brain where they are transformed into electrical signals.
Neurons form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis, which is mediated by molecules called neurotransmitters. Since the electrical impulse cannot jump directly from one neuron to another, these neurotransmitters are needed. When the active neuron produces them, the next neuron in the network detects them and becomes electrically charged. Once this has happened, it produces neurotransmitters again so that the next one becomes electrically activated. This is how the electrical impulse reaches the brain.

What is a main difference between Mercury and Neptune?
Mercury is an inner planet with a thicker atmosphere and a longer year than Neptune.
Mercury is an inner planet with a thinner atmosphere and a shorter year than Neptune.
Neptune is an inner planet with a thicker atmosphere and a shorter year than Mercury.
Neptune is an outer planet with a thinner atmosphere and a shorter year than Mercury.
Answer:
B because Mercury's orbit is 88 days and Neptune's is 164 earth years
Mercury is an inner planet with a thinner atmosphere and a shorter year than Neptune.
What is Mercury and Neptune?
Since 2011, Neptune has spent 12 years in the sign of Pisces, which it rules and enjoys being in. Mercury spends just 15 to 60 days in each sign of the zodiac, but because of the Mercury retrograde, they come together and hang out for a while.
This is incredibly uncommon. It may be said that Mercury, the hare, is enjoying a Long sleep with Neptune in a dreamy fog and has forgotten his responsibilities as a courier around the Earth.
When Mercury conjoined the Sun on March 14 at 24 degrees Pisces and then today, on March 25, when Mercury conjoined Neptune at 16 degrees Pisces, this was notably felt.
Therefore, Mercury is an inner planet with a thinner atmosphere and a shorter year than Neptune.

Mitosis vs Meiosis, someone help me with this, ill give brainiest.
♡ hi there!! i tried to go back to my notes, but i couldn't find anything. but here if an explanation i found. ♡
different: mitosis consists of one stage whereas meiosis consists of two stages. mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.
similar: both involve cell division, both the processes occur in the M-phase of the cell cycle. In both cycles, the stages are common – metaphase, anaphase, telophase and prophase. synthesis of DNA occurs in both.

List 5 ways that phosphorous is essential to plants & animal life on Earth.
Answer:
El fósforo (P) es esencial en todas las formas de vida conocidas, dado que constituye un elemento clave en muchos procesos fisiológicos y bioquímicos. Se trata de un componente presente en todas las células de todos los organismos vivos. El fósforo aparece en estructuras complejas de ADN y ARN que, al contener y codificar la información genética, controlan todos los procesos biológicos en las plantas. Además, el fósforo es un componente fundamental del sistema de transporte de energía en todas las células.
El fósforo no aparece aislado en la naturaleza, sino que se encuentra siempre combinado con otros elementos con los que forma los fosfatos que pueden ser muy complejos y presentarse bajo distintas formas en los suelos, el agua, las plantas, los animales y el hombre. Por tanto, se utilizará la palabra “fósforo” de forma genérica en lugar de identificar el fosfato concreto, aunque en la mayoría de los casos, se ofrecerán valores numéricos como P2O5 .
Hasta una época relativamente reciente, el crecimiento de las plantas y de los animales, y por extensión, la productividad de la agricultura, se veían limitados por la falta de fósforo, ya que anualmente solo se disponía de unas pequeñas cantidades de las rocas y de los minerales del suelo gracias a la acción erosiva de los elementos. Cuando los agricultores comenzaron a utilizar fertilizantes en el siglo XIX, los niveles de fósforo disponible para las plantas en muchos suelos eran todavía muy bajos. Por eso, hasta que no se comenzó a aplicar fósforo, la respuesta a otros nutrientes, especialmente al nitrógeno, era muy pequeña, es decir, que el fósforo era el nutriente limitante del crecimiento de las cosechas.
El fósforo desempeña un papel fundamental en la fotosíntesis, proceso por el que las plantas absorben la energía del sol para sintetizar moléculas de carbohidratos, es decir, de azúcares, que son transportados a los órganos de almacenamiento de las plantas. Este proceso es esencial para todas las formas de vida y constituye el primer paso en la cadena para producir alimentos, piensos y fibras.
Las raíces de las plantas absorben el fósforo del agua presente en el suelo y que se denomina solución acuosa del suelo.
Sin embargo, los compuestos de fósforo no son muy solubles y, como consecuencia, la cantidad de fósforo que la planta puede tomar de la solución acuosa del suelo tiende a ser mucho menor de la que necesita, especialmente cuando la planta se encuentra en un periodo de fuerte crecimiento. Por eso, el fósforo de la solución acuosa del suelo debería reponerse con una frecuencia de diez veces al día en esos periodos.
En un día, una cosecha de rápido crecimiento puede absorber el equivalente a cerca de 2,5 kg de P2O5 por hectárea (una hectárea equivale a 10.000 m2 ). De esto se deduce, por tanto, que es necesario que existan reservas adecuadas de fósforo en el suelo y que esas reservas puedan estar disponibles con facilidad. La mayoría de los suelos no abonados contienen una cantidad demasiado pequeña de fósforo, fácilmente aprovechable, para dar respuesta a la gran demanda de las cosechas, en especial durante ciertos periodos del ciclo de crecimiento. De ahí, que se imponga la necesidad de aplicar fertilizantes que contengan fósforo.
La carencia de fósforo afecta no solo al crecimiento de la planta y al desarrollo y rendimiento de la cosecha, sino también a la calidad del fruto y a la formación de las semillas. Asimismo, la carencia de fósforo puede retrasar la maduración de las cosechas, con lo que se retrasa la recolección y se pone en riesgo la calidad del producto.
