Answer:
Every cell in the body originates from a single fertilized egg called a zygote. The zygote divides repeatedly to produce an embryo. These embryonic cells continue to divide, differentiating into all the cell types present in the body of all humans (and other mammals), from a new-born baby to an elderly adult
Answer:
The zygote

How is water stored on Earth during the water cycle?
Water can be stored on the surface of the Earth and underground. The water storage areas are known as reservoirs and include oceans, glacier ice, groundwater, lakes, soil moisture, living organisms, the atmosphere, and rivers.
How is cell division different in prokaryotes and eukaryotes
Answer:
Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other cell structures. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles.
Explanation:
Answer:
Prokaryotes have fewer cells structures, have no nucleus, and have a singular chromosome. Eukaryotes, however, have multiple chromosomes that contain a nucleus, cell structures, and many organelles.
explain the circulation of blood
Explanation:
blood comes into the right atruim from the body
Answer:
The circulation of blood is where basically the blood comes or goes into the right atrium from the body, this then moves into the right ventricle and is then pushed into what is called the pulmonary arteries in the lungs of a human. Once it has picked up oxygen, the blood will then travel back to the heart through the pulmonary veins, but this time it will go into the left atrium, so to the left ventricle and including out to the human body's tissues through the aorta.

The hypothalamus is the link between the nervous system and the endocrine system. The pituitary gland is called the master gland because it influences the release of hormones by other glands in the endocrine system, malfunctioning of which releases growth hormone, which can lead to gigantism.
What is Pituitary gland?The pituitary gland is defined as a small, pea-sized endocrine gland located at the base of your brain below the hypothalamus that releases several important hormones and controls the function of many other endocrine system glands.
There are four hormones which is secreted by the anterior pituitary gland that control the functions of other endocrine glands where these hormones include thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), and luteinizing hormones (LH). The pituitary gland is called the master gland.
Thus, the hypothalamus is the link between the nervous system and the endocrine system while the pituitary gland is called the master gland

Para ya por favor Cual de los siguientes planteamientos se cumplen en relación a la energía en un ecosistema * A.La energía fluye de los heterótrofos a los autótrofos B.La energía, a menudo se libera de un ecosistema en forma de luz C.La organización de productores-consumidores y descomponedores muestra como la energía se concentra de manera mas alta en los descomponedores D.Para la mayoría de los ecosistemas la energía proviene de la luz
Answer:
D.Para la mayoría de los ecosistemas la energía proviene de la luz
Explanation:
Los ecosistemas requieren de un suministro constante de energía para poder sustentar la vida. A excepción de ecosistemas basados en fuentes hidrotermales, en general este aporte energético proviene del sol que suministra energía lumínica la cual es convertida por los organismos productores (por ej., plantas y algas) en compuestos orgánicos. Los productores representan la fuente de energía y alimento de consumidores primarios (por ejemplo, herbívoros), los cuales a su vez sirven de sustento para consumidores secundarios (por ej., carnívoros), estos suministran de alimento a los consumidores terciarios y así sucesivamente. Finalmente, los descomponedores son aquellos microorganismos que se alimentan de los restos orgánicos obtenidos a partir de productores y consumidores.
Do plants with shallow roots or deep contain a greater amount of radioactive substances?
Answer:
yes
Explanation:
roots that are deep get to more radioactive material underneath the earth
It is correct that the roots that are deep contain a greater amount of radioactive substances.
What are radioactive substances?Radioactive substances are atoms that naturally decay. They have the ability to emit alpha particles, beta particles, and gamma radiation.
Because they cannot be turned off like X-ray sources, they are more difficult to control.
Radioactive substances emit three types of dangerous radiation: alpha particles, beta particles, and gamma rays.
A substance is said to be radioactive if it contains unstable nuclei and can naturally release energy by shedding high-speed charged particles in an attempt to achieve a stable state.
However apart from the heat produced by the planet's establishment, radioactive potassium, uranium, as well as thorium are presumed to be the three principal sources of heat in the Earth's interior.
Thus, it can be concluded that the deeper roots will encounter more radioactive substances.

Explain why your model improves upon the student’s original model. How would your model help someone who was learning about photosynthesis for the first time?
Answer:
Determine how many groups you will have.
Prepare ping-pong balls.
Collect egg cartons.
Prepare the egg cartons.
Prepare “energy tokens.”
Post signs in the classroom.
Prepare filled H20 and C02 “molecules.”
Explanation:
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
Answer:
This new model may better explain the elements required for photosynthesis to occur. Sunlight, water, and carbon dioxide are required for the plant to produce its own food. Someone who is unfamiliar with the process of photosynthesis must begin with the basics and then build on this knowledge.

Explanation:
Use the model of meiosis that you made earlier in the lesson to explain how crossing over contributes to genetic diversity. How did you modify your model? How do you think crossing over affects the expression of certain traits compared to the cells where crossing over didn't occur?
Hello. You have not shown the model of meiosis to which the question refers, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.
Crossing over is a genetic phenomenon that occurs when two sister chromatids are broken at some points and the pieces are exchanged between them. these exchanges cause the appearance of completely new gene sequences, which can completely affect the expression of stretches in the cells where the crossing over happened, since this cell will have a different gene sequence than the others.
As you may already know, chromosomes are formed by two filaments, called a chromatid. These filaments are united by the centromeros and the union of two filaments and a centromero is called sister chromatides.

what are the respiratory movement of Man?Are they same in a grasshopper or a fish?
Answer:
Respiratory movements are the muscular movement that helps in the entry or exit of air to and from the respiratory organs of an animal. The mechanism of the respiratory movement can be different in different animals.
In man, the respiration movements involve inspiration and expiration by the expansion and contraction of the thoracic cavity that leads to the flow of oxygen and carbon dioxide to and from the lungs.
In insects such as grasshopper, the flow of the air moves through the tracheae by rhythmic relaxation and contraction of abdominal muscles. In fish respiratory movements involves entering the oxygen through their mouth and release CO2 from the gills.
