The food web starts as the plankton are eaten by worms and mollusks, which are eaten by shrimp, which are eaten by crabs and fish, and fish eat the shrimp, and birds eat the crabs, shrimp, and fish. I hope my answer helps.
Starting at the plankton and flowing upward. Therefore, option (C) is correct.
What is flow of energy in food web?A food web describes the transfer of energy and nutrients from one organism to another within an ecosystem. The flow of energy in a food web starts with producers, such as plants or algae, which convert energy from the sun into organic matter through photosynthesis. This organic matter is then consumed by herbivores, which are then consumed by carnivores or omnivores, and so on. Each level of the food web represents a trophic level, with energy and nutrients being passed up the chain as organisms consume one another.
As energy moves up the food web, some of it is lost through various processes such as respiration, heat loss, and waste production. This means that the amount of energy available at each trophic level decreases, resulting in a pyramid-shaped structure of the food web. The flow of energy through a food web is essential for maintaining the balance and stability of an ecosystem, as it determines the survival and population of different organisms within it.

Which of the following statements best describes a
stem cell?
Stem cells can develop into other types of
cells.
Stem cells are used as backup for
reproduction,
Stem cells are responsible for creating
somatic cells.
Answer:
stem cells are used for backup reproduction.
Explanation:
because Stem cells provide new cells for the body as it grows, and replace specialised cells that are damaged or lost. They can divide over and over again to produce new cells. they can change into the other types of cell that make up the body.
The statement that best describes stem cell is- “Stem cells can develop into other types of cells”. Hence, option A is correct.
What are stem cells?Stem cells are the basic undifferentiated cells of the body that can be formed into any other type of cell as the requirement of the body. They can self-renew themselves indefinitely and give rise to differentiated cells of the body.
They are also called “master cells” or totipotent cells, as they have total potency to regenerate.
There are many sources of stem cells, such as:
Embryonic stem cells-These cells are extracted from the embryo when they are 3–5 days old in the blastocyst stage of embryonic development. They are pluripotent stem cells, which means they can form more stem cells or other types of cells.Adult stem cells-These cells are found in very small quantities in the adult tissues such as bone marrow, fat, brain tissue, blood vessels etc. In comparison to the embryonic stem cells, they have less ability to be give rise to other type of cell of the body. Perinatal stem cells-These cells are discovered by the researchers in the amniotic fluid as well as the umbilical cord and can give rise to many specialized cells of the body.Therefore, stem cells can be developed into other types of cells. Hence, option A is correct.

Which sources would preserve the soft tissues of an early mammal
Answer:
Amber , permafrost and tar
Explanation:
Amber , permafrost and tar would preserve the soft tissues of an early mammal. Soft tissues of early mammals would preserve in case of amber in Russia. and frozen soil in the Arctic. Although hair and mammary glands are soft tissue but they are not readily fossilized as mammary glands and hairs are derived from dermic structures
Soft tissue preservation is rare and requires rapid burial in environments that are oxygen-free and low-energy. Examples of such preservation include burial in volcanic ash, trapping in amber, and freezing in glaciers. These conditions help prevent decay and allow soft tissues to remain intact over time.
Soft tissue preservation is rare due to the need for rapid burial to prevent bacterial decay. Such preservation typically occurs in environments that are oxygen-free and low-energy. Examples include:
Burial in volcanic ash, which rapidly covers and preserves remains.Trapping in amber, as seen in perfectly preserved ancient insects.Frozen in glaciers, as evidenced by preserved mammoths with intact skin and hair.These conditions prevent the action of bacteria and other decomposers, allowing soft tissues to remain intact over millions of years.

Which of the following statements about nuclear energy is true?
a. Nuclear energy cannot be contained nor controlled.
b. Nuclear energy is contained in nuclear bonds.
c. Nuclear energy is less efficient than other energy forms.
d. All of the above are true.
Please select the best answer from the choices provided
ОА
Answer:
The answer is b. Nuclear energy is contained in nuclear bonds.
Explanation:
As nuclear energy can be contained and controlled, it is more efficient and sometimes similar to other energy forms.
Nuclear energy is contained in nuclear bonds. Therefore, the correct statement is b.
Nuclear energy is the energy that is contained within the nucleus (core) of an atom. It is the energy that holds the protons and neutrons together in the atomic nucleus.This energy is released in nuclear reactions, such as nuclear fission (the splitting of atomic nuclei) or nuclear fusion (the merging of atomic nuclei). In nuclear fission, the energy is released when heavy atomic nuclei, such as uranium-235 or plutonium-239, split into smaller nuclei, along with the release of a significant amount of heat energy.The energy released from nuclear reactions is harnessed and used to generate electricity in nuclear power plants.Nuclear energy is highly efficient in terms of energy release. It is known for its high energy density, which means that a small amount of nuclear fuel can produce a large amount of energy.The other statements are not true:
a. Nuclear energy can be contained and controlled, as evidenced by the operation of nuclear power plants worldwide. Stringent safety measures and engineering controls are in place to ensure the safe and controlled use of nuclear energy.
c. Nuclear energy is not necessarily less efficient than other energy forms. In fact, nuclear energy is known for its high efficiency and low greenhouse gas emissions when compared to some other forms of energy generation, such as fossil fuels. However, there are safety and environmental considerations associated with nuclear energy that need to be managed carefully.
So, the correct answer is option b, as it accurately describes the nature of nuclear energy.
