3. When the animals eat the plants they obtain energy and raw materials required for their life processes.
4. Cellular respiration generates carbon dioxide as a waste product that is released into the atmosphere.
Explanation:
Naturally, Plants and animals have their own roles to play in the environment. Photosynthesis is a process carried out by plants to synthesize their own food in form of organic molecules. This process kicks off energy and matter transfer in ecosystems.
According to this question, animals like mice and rabbits were introduced into a green house to see the effect of cellular respiration. Based on this, energy and matter flow will occur in the greenhouse as follows:
- Plants use the sun’s energy to combine carbon dioxide from the atmosphere with other carbon compounds.
- Plants synthesize large carbon-based molecules, including lipids, proteins, and complex carbohydrates.
- When the animals eat the plants they obtain energy and raw materials required for their life processes.
- Cellular respiration generates carbon dioxide as a waste product that is released into the atmosphere.

What condition is necessary for a genetic change that occurs in one individual to be spread to other individuals?
A. a common gene pool
B. a common phenotype
C. a similar habitat
D. a similar niche
Answer:
a
Explanation:
A common gene pool is a need for a genetic alteration that occurs in one person to be passed on to other people. The aggregate genetic makeup of a species or group is referred to as its gene pool.
What is the scenario with the genetic change in the population ?The whole of the population's alleles, or genetic variations, that may be transmitted from parents to children through reproduction. If two people share a gene pool, a genetic alteration experienced by one person can transmit to the other person.
This is so that the person who had the genetic change's progeny won't inherit the altered gene. It is not essential for a genetic modification to be passed on to other people for them to have a common phenotype. The traits or outward appearance of a phenotype of an organism, which is based on its genotype (the organism's genetic make-up). Although an organism's genotype can affect its phenotype, there isn't always a clear connection between the two.
Consequently, a shared phenotype is not a need for a genetic mutation to be passed on to other people. Similar environment and niche requirements are not essential for a genetic mutation to propagate to other people, either.
A niche is the function that an organism plays in its environment, whereas a habitat is the actual setting in which an organism lives. Although changes in habitat or niche can have an impact on an organism's genetic composition, they are not prerequisites for a genetic mutation to propagate to other people.

In comparing the number of chromosomes in a body cell to that in a sex cell, a body
cell has twice the chromosome number of a sex cell
True
False
Answer:
it is True for this question
It is true that the number of chromosomes is twice in a body cell in comparison to the sex cell. Therefore, option A is correct.
What are chromosomes?The thread-like chromosomes that convey the genomic information from cell to cell are formed of protein and a single DNA molecule. Chromosomes are found in the nucleus of cells in both plants and animals, including humans.
The very long, thin DNA fibers in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.
Sex chromosomes and autosomes are the two primary types of chromosomes found in many organisms with distinct sexes. Body cells are diploid and sex cells are haploid, which means the number of chromosomes is twice in the body cells as that in the sex cells. Therefore, option A is correct.

Diffusion of nutrients across a cell membrane can be called a form of Multiple Choice bulk transport. exocytosis. osmosis. active transport. passive transport.
Answer:
passive transport
Explanation:
Diffusion is one of the ways molecules/substances move or is transported. It is the process whereby substances move from a region of higher concentration to a region of lower concentration until there is an even distribution. Movement via diffusion occurs down a concentration gradient i.e high to low.
Since diffusion occurs down a concentration gradient, which is difference in concentration of a substance, it requires no energy in form of ATP to occur. This kind of transport which requires no energy input is called PASSIVE TRANSPORT, in contrast to active transport which requires.

Which of the following best describes the theory of natural selection?
The genetic makeup of a population gradually changes from one generation to the next due to spontaneous mutation.
Living organisms change over time due to the flow of energy, which is a key factor in determining what kinds of organisms can live in a particular community.
There is variation among the members of a species. Some of this variation is genetically determined and so can be passed on to future generations on chromosomes inherited from the parents.
Some individuals have genes that increase their chances for survival and reproduction. These individuals are more likely to reproduce and pass on their genes, causing their genes to become more common in the next generation.
There is a struggle for existence among the members of a population. Cooperation allows several species to exist in one area, while competition tends to eliminate species.
Answer:
Some individuals have genes that increase their chances for survival and reproduction. These individuals are more likely to reproduce and pass on their genes, causing their genes to become more common in the next generation.
Explanation:
The basic idea of natural selection is that environmental conditions determine how well the characteristics of organisms contribute to the survival and reproduction of the organism; organisms that do not have these traits may die before reproduction or be less fertile. As long as environmental conditions remain the same or close enough for these traits to remain adaptive, these traits will become more common in populations. The loss of an ecological niche of a species or overcrowding as a result of an increase in abundance can significantly alter the adaptive characteristics required for survival. In this case, and also in any environment where survival is determined more by ecology than secondary sex characteristics, ecological choice takes place.

• Distinguish between cytoplasm and cytosol
Answer:
Cytoplasm Meaning
Cytoplasm is the component of the cell surrounded by the cell membrane. All the cell organelles are present in the cytoplasm. It helps in large cellular activities such as glycolysis or nuclear division. The inner concentrated region of the cytoplasm is called the endoplasm, whereas, the outer region of the cytoplasm is called ectoplasm.
Cytosol Meaning
Cytosol is known as the matrix of the cytoplasm. It surrounds the cell organelles in eukaryotes. In prokaryotes, all the metabolic reactions occur here.
Thus, we can infer that while cytosol is the fluid contained in the cell cytoplasm, cytoplasm is the entire content within the cell membrane.

Use Sammi's model as an example to explain why cells are the building blocks for human bodies?
Answer and Explanation:
The cell is a basic functional and structural unit of life. All living organisms are made up of cells. The human body contains approximately 100 trillion cells in our blood, skin, nerves, muscles, bones, and brain. Humans have 200 diverse forms of cells that come in different sizes and shapes. Each cell performs a specific function in the human body. There are four main types of cells: nerve cells, muscle cells, epithelial cells, and connective tissue cells. Nerve cells are specific for communication. These cells send signals from the brain to glands and muscles that control functions. Nerve cells receive sensory information is from the skin, the ears, and the eyes and send this information to the brain. Epithelial cells cover the interior of hollow body organs such as digestive organs or blood vessels. Muscle cells are specific for contraction. The body cannot move without muscles. Connective tissue cells protect against foreign invaders and also provide strength to the body.
Answer:
Cells are the building blocks for human bodies since cells have diverse sections and each performs specific duties. A cell refers to the simplest, basic unit of life. The circulatory system's various components are depicted on the model using everyday objects. From the model, it can be seen that some of the parts that are represented include the heart, blood vessels, capillaries, and digestive tract. This illustrates that for blood to be pumped into the body, different organs have specific roles to play just like the cells have different functions to play in the human body.

what will happen if one of the levels in the biological organization will not perform its function properly?
Answer:
It would affect the functionality of the other levels including the organism
Explanation:
The level of biological organization is a hierarchical step consisting of how a multicellular organism forms. According to this level of organization, CELLS are the simplest unit of life and the collection of cells with a similar function is termed TISSUE. Tissues form ORGANS, organs form ORGAN SYSTEMS and finally, a collection of all the systems in the body forms the ORGANISM.
Based on this, one would observe that each level is related to the next in such a way that one forms from the other. Hence, if one of the levels in the biological organization will not perform its function properly, the other levels will be affected. For example, if the kidney cells do not perform it's function, it would affect the functionality of the kidney tissues, kidney organ, the excretory system, and the organism at large.
If one of the levels in the biological organization does not perform its
function properly, it will have a negative effect on the other levels and
organisms as a whole.
Organism comprises of cells which is the smallest unit of life and aggregates to form tissues. The tissues then aggregate to form organs and the organs aggregate to form a system.
When one of the levels are affected , it brings about non-functionality of the
system which is the highest level and the organism in which they are found in for its optimal functioning and metabolic processes.
