As you have observed, animal hairs usually have a large medulla composed of air-filled compartments. These air-filled compartments are present for a reason and can actually help hair do its job better. Describe one reason that might explain why having a hair made of air filled compartments could be helpful to an animal.
PLEASE HELP
Answer:
to provide insulation
Explanation:
The medullary index is the proportion of the diameter of the hair medulla in regard to the diameter of the entire hair: The equation to calculate the medullary index is medulla diameter/hair diameter. In animals, the hair medulla is generally thicker compared to humans (medullary index approximately 0.5 and 0.33, respectively). The thicker the diameter of the hair medulla, the better is the insulation.

Two differences between hormones and the nervous system
Answer:
Hormones can be proteins, lipids or cholesterol-based molecules. Neurotransmitters are protein. The main difference between hormones and neurotransmitters is that Hormones are produced in the endocrine glands and released into the bloodstream where they find their movement targets at a distance from their origin. In contrast, Neurotransmitters are released into the synaptic space by a terminal of an excited presynaptic nerve cell and transmit a nerve signal to the neighboring postsynaptic nerve cell.
Explanation:
Answer:
the nervous system and endocrine system (hormones) is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.

Most mutations that cause cancer occur within body cells, and body cell mutations are not inherited. If cancer is not inherited, why does cancer statically appear to run in families?
Family members have a similar genetic make-up that may make them predisposed to cancer.
Family members are exposed to similar environmental conditions.
Family members have a widely varied genetic make-up that can be affected by specific mutagens.
Family members share the contagious mutagens that can be passed by close exposure.
Answer:
Family members have a similar genetic make-up that may make them predisposed to cancer.
Explanation:
Variation in certain genes can increase the risk of developing certain cancers. This is why certain cancers run in families. There are lots of examples where the risk factor is small, but in some cases, the risk factor is very large.
For example, mutations in BRCA1 are very highly linked to the risk of breast cancer. As a result, many women with mutations in this gene opt to get a mastectomy to reduce their chances of developing breast cancer.

Which of the following presents the best argument as to the role of the cow in this cycle?
Answer:
Cow dung helps in balancing the environment and kills germs
Explanation:
Cow dung is used for fertility of the soil. It is also used for the control of pest in the plants. When heated cow dung can be used to cook food where there are lack of wood available. Also when it is heated it releases the gases which kills germs present in the air.
Answer:
The cow eats plants and produces carbon dioxide through cellular respiration. The plants, which gain energy from the sun, then take carbon dioxide from the atmosphere and use it in photosynthesis.

Which best explains why the sun maintains its size and shape?
A. Pressure caused by high temperatures are balanced by gravity.
B. The sun burns from its core to its surface.
о
C. Forces exerted by orbiting planets cause the sun to rotate.
Answer:
A
Explanation:
The Suns own weight keeps itself together and keeps its size and shape. all things have gravity. in this case, the sun keeps it shape with balancing its gravity with the pressure.
The best explanation of why the sun maintains its size and shape is forces exerted by orbiting planets cause the sun to rotate. The correct option is C.
What is orbiting?"Orbiting" is one of those digital dating terms that perfectly describes what many of us have experienced but didn't realize had a name. It's when someone you were dating tells you they're no longer interested but keeps in touch with you on social media.
The Sun's own weight holds it together and maintains its size and shape. Everything has gravity. In this example, the sun maintains its shape by balancing gravity and pressure.
Planets orbit the sun in elliptical orbits, with the sun slightly off-center of each ellipse.
Therefore, the correct option is C. Forces exerted by orbiting planets cause the sun to rotate.

Alvinella pompejana is known as the Pompiee worm. This organims is found in the deep hydrothermal vents in the Pacific ocean. Thus, the correct option is A.
What is Pompiee worm?Alvinella pompejana, the Pompeii worm is a species of the deep-sea polychaete worm. It is an extremophile found only at the hydrothermal vents of the Pacific Ocean, discovered in the early 1980s off the Galápagos Islands by the French marine biologists.
The Pompeii worm (Alvinella pompejana) is a deep-sea polychaete vermiform extremophile. This organism can survive at extreme conditions. It is possible because of their bacterial coating which redistributes the heat to keep the worm cool. This bacteria not only help regulate the temperature of the worm but they also break down minerals from the vent to aid their host.
Therefore, the correct option is A.

c.clumped
d. density
Answer:
A) Even
Explanation:
got it right on edge :)
Orange trees planted in a grove or orchard would most likely fall in the even category of population distribution. The correct option is a.
What is population distribution?Population distribution is how the population of something, plants, animals, or humans is distributed in specific areas. It specifies where people live or where they are not living.
There are three types of population distribution:
Uniform dispersion - In this distribution, the population is uniformly or evenly distributed in the areas. Even distribution comes under this distribution.Random dispersion - there are no predictable patterns in this dispersion. They are randomly present anywhere.Clumped dispersion - This distribution shows the bunch or group of population is areas then there is no population, and then there is a a bunch of population in another place.Thus, the correct option is a. even.

Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen?
Answer:
Oxygen cycles keeps the flow of oxygen at a constant rate.
Explanation:
The oxygen constitutes about 20% of the gaseous components in the atmosphere and it's being renewed continuously by the various microorganism and primary producers as green plants that use photosynthesis and converts the sunlight and carbon dioxide to water and releases oxygen. Oxygen cycle makes life possible as most of the elements are combined with oxygen in some way or another and are found on the lithosphere, hydrosphere, and atmosphere even biosphere hence its is present insufficient amounts.
Answer:
A.) The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle.
