The size and position of their centres are the same for homologous Chromosomes
The statement that is correct about plasma membranes is that both plant cells and animal cells have flexible plasma membranes (option C).
<h3>What is the plasma membrane?</h3>
Plasma membrane is the semipermeable membrane that surrounds the cytoplasm of a cell. The semi-permeability of the plasma membrane means it allows some molecules through but blocks other substances.
The plasma membrane is the cellular structure that protects and encompasses the cell's content.
All living organisms possess the plasma membrane, which is also called cell membrane.
Therefore, the statement that is correct about plasma membranes is that both plant cells and animal cells have flexible plasma membranes.

Answer:
I think that the second picture was correct
Explanation:
gravitational field is a model used to explain the influence that a massive body extends into the space around itself, producing a force on another massive body. Thus, a gravitational field is used to explain gravitational phenomena, and is measured in newtons per kilogram (N/kg)
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.
Natural selection ensures that animals with features that increase their chances of survival are more likely to live and pass those traits on to their progeny.
Animals adapt to their surroundings over a lengthy period of time, which causes those changes. The evolution of adaptations happens across many generations.
<h3>What is an adaptation?</h3>
- A physical or behavioral characteristic of an animal that enhances its ability to survive in its environment is known as an adaptation.
- To put it another way, an adaptation is something a species does or has on them that makes it easier for them to locate food, water, mates, and shelter.
- Among the adaptations that helped animals live and prosper on land are:
- Gas exchange using a moist membrane
- The ability to traverse land (limbs instead of fins)
- The capability of body water conservation
- The capability of reproduction and early habitability
- The capacity to endure fast environmental changes
<h3>What are the types of adaptation?</h3>
Depending on the environment, there are three basic types of adaptations: behavioral, structural, and physiological.
- Physiological- When an animal's body's internal mechanisms adapt to its surroundings.
- Structural - Over the course of millions of years of evolution, the animal's bodily features alter.
- Behavioral - Animals adjust their behavior in reaction to their environment.
