What is a function of the backbone in animals?
A. It protects against predators.
B. It regulates blood glucose.
C. It surrounds the spinal cord.
D. It limits movement.
Answer:
C>
Explanation:
just took the test hope it works.
The main function of the backbone in animals is that It surrounds the spinal cord. Vertebrate bodies are supported structurally by their backbones, hence option C is correct.
How backbone is important in animals?The vertebral column's main job is to protect the spinal cord, but it also stiffens the body and serves as an attachment point for several muscles, the pectoral and pelvic girdles, and the spinal cord.
In contrast to cartilaginous or bony vertebrates, any animal without a vertebral column, or backbone, is referred to as an invertebrate. Invertebrates make up more than 90% of all species of living animals.
Therefore, the vertebral arch, also known as the bony arch on the back of a vertebra that surrounds the spinal cord, is made up of the spinous process and lamina.

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, the correct option is option A.
What is matter?Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.
Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.
So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Water as deep as 60 m is still affected by the wind at the earth’s surface.
Therefore, the correct option is option A.

What term describes a species whose removal would affect many other species, both directly and indirectly
A. predator species
B. Keystone species
OC. cascading species
OD. phoresy species
Next
Answer:
Keystone species
Explanation:
Keystone species is that species whose presence and number in the ecosystem plays an important role in balancing the ecosystem and without them, the other species would be affected directly and indirectly.
A dominant predator is considered to be a keystone species because the removal of that predator allow their prey to explode in numbers which will decrease the overall biodiversity of the area. Prairie dogs, otters, bison are the examples of keystone species. So the correct answer is B. Key stone species.

Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait
are called ______. A) phenotypes B) alleles
C) DNA
D) mutations E) genotypes
Answer:
The answer is B) alleles
Explanation:
Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.
What do you mean by traits?Traits may be defined as the appearance or manifestation of the desired characters. Traits are also known as phenotypes.
Every factor or gene has two alternative copies, one comes from the father and one comes from the mother. These two copies are present in the same location on the homologous chromosome. They are known as alleles of each other.
Therefore, Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.

The wings of insects, bats, and birds are structurally different but achieve similar functions. This is an example of a/an _______. The peppered moth provides an example of _______, as the predominant color of moths changed over time as pollution dictated which color was best camouflaged for protection from predators. Respond to the following based on your reading. Two species, a cactus and a Venus fly-trap, have a water intake system that's similar in function but not in structure. What type of structure is this? A scientist is trying to determine if two species are closely related or if they just have the same external features. What would you look for to make this determination? You go to school and discover that your friend got admitted to the hospital for a burst appendix. You want to learn if the appendix serves a function in our bodies. What would you need to research? A species of beetle in Africa looks really similar to a different species in South America. How would the environment influence species development? Why does Australia have so many genetically distinct organisms?
Answer:
homologous structure
analogous structure
natural selection
This is known as an analogous structure.
To make this determination, you need to think about if the features are the same in function or also in structure. Features that have a closely related structure and function are likely to be related.
To learn more about why your friend is in the hospital, you should research vestigial structures.
These two beetles aren't closely related, but they look and behave similarly. This is because they live in the same environmental conditions and likely share a common ancestor that lived in Gondwana (the supercontinent that included the southern continents before they split apart through plate tectonics).
Australia has so many genetically distinct organisms because it has been separated from other bodies of land by water for a very long time. This has created an opportunity for long-term independence of other geographic areas.

Immune system overreacts to an antigen part of the immune system does not function properly the body's immune system attacks its healthy cells, mistaking them for pathogens masses of cells form and steal nutrients from healthy.
What do you mean by Allergy?Allergy may be defined as a reaction by our immune system to something that does not trouble most other people. It affects a person more specifically.
When a person gets affected by any allergy, the immune system of that person may overreact by producing more antibodies. These antibodies attack the allergen particles and cause adverse symptoms.
A person who has allergies has them because his or her body over reacts to a material that would otherwise be ignored. It is an overreaction of the immune system triggering a immune attack response that is unneeded.
Therefore, a person who has allergies has a compromised immune system because the body's immune system overreacts to an antigen.
