A biologist analyzes DNA sequences in three different primates. She finds primates "A" and "B" have almost exactly the same DNA sequences. DNA sequences in primate "C" are significantly different from those of primate "A" and primate "B". This information allows the biologist to infer that
Answer:
primates A and B are more closely related to each other than they are to primate C
Explanation:
The study and the comparison of DNA sequences of various species is used in decoding genomic information as well as determining closely related or distant related species.
Closely related species are known to have almost the same DNA sequences when studied. For example, chimpanzees are known to be most closely related to humans and this because, studies show that they share about 99% of their DNA with humans. So also, although monkey is a primate, its DNA sequences is significantly different from humans and chimpanzee, making it less closely related to either humans or chimpanzee compared to the relationship between human and chimpanzee.
the distance from earth to the north star is about 430 light years. which of the following statements describes why scientists use the light year unit to measure distances in space?
a. a light year unit is very small and distances in space are very small
b. a light year unit is very small and distances in space are very large
c. a light year unit is very large and distances in space are very small
d. a light year unit is very large and distances in space are very large
Answer:
i am not sure but i think is D
A light year unit is very large and distances in space are very large. So, the correct option is D.
What is Light year?A light year is defined as the larger unit of length which is used to express astronomical distances and is approximately equal to 9.46 trillion kilometers or 5.88 trillion miles.
A light-year is expressed as the distance that light travels in a vacuum in one Julian year, which is 365.25 days because it includes the term "year", the term light-year is sometimes misunderstood as a unit of time.
1 light-year = 9460730472580800 metres
Light year is used as a unit to express distances to celestial objects, for example, if a star is 4 ly away from earth, it means that light from the star will take 4 earth years to reach us.
Therefore, a light year unit is very large and distances in space are very large. So, the correct option is D.

which bone layer holds calcium and other minerals
Answer:
In addition to its mechanical functions, the bone is a reservoir for minerals (a "metabolic" function). The bone stores 99% of the body's calcium and 85% of the phosphorus. It is very important to keep the blood level of calcium within a narrow range. If blood calcium gets too high or too low, the muscles and nerves will not function. In times of need, for example, during pregnancy, calcium can be removed from the bones. This process is carefully regulated by hormones and is discussed more completely in the section about hormones.

Provide a summary of biologist Stephen Stearns’ findings in how Natural Selection may be working today in humans.
Answer:
Stephen Stearns states that natural selection doesn't mean the survival of the fittest organisms, but rather this mechanism is illustrated by the selective reproduction of the fittest. Natural selection can be classified into distinct types, including directional, disruptive and stabilizing selection, which are in turn based on sexual selection. These types of selection are driven by different outcomes that have different dynamics.

She creates the Punnett square cross below to show sex inheritance. She come to know that both parent determines the sex of a baby and it is when you put xx and xy on a punnet square there are equal amounts male and female.
How Human sex gets decided?Human sex gets decided by the function of SRY gene which possessed by with or without of Y chromosome. The hormone of anti-mullerian and testosterone produced from cells when activating the SRY gene. It generally confirms the development of single-male reproductive systems.
The scenario in humans, the sex ration gets affected by the male parent's hormone level. Also, in XY sex evaluation system, the sperm of male takes part in X or Y chromosome whereas the ovum from female contributes to X chromosome. This greatly results in offspring - either male (XX) or female (XY).

What does the circulatory system do?
A. Sends hormones to the body
O B. Moves blood around the body
C. Brings oxygen into the body
O D. Defends against invaders
Moves blood around the body
The circulatory system moves blood around the body. Therefore, option (B) is correct.
What is circulatory system?The circulatory system, also known as the cardiovascular system, is responsible for the circulation and transportation of blood, oxygen, and nutrients throughout the body. It includes the heart, blood vessels, and blood. The heart pumps blood to the lungs to become oxygenated, and then circulates the oxygen-rich blood to the rest of the body through arteries.
Veins carry deoxygenated blood back to the heart, where it is pumped to the lungs to receive oxygen. The circulatory system also plays a role in removing waste products from the body, such as carbon dioxide, and helps to regulate body temperature, pH balance, and fluid balance. The circulatory system is essential to maintaining the proper functioning of all cells, tissues, and organs in the body.

Answer:
Option D, renewable resource
Explanation:
A renewable resource is the resource which can be replenished after every use. Or in general the time taken by it to replenish must be small. For instance, fossil fuels too are renewable but the time taken by them to renew is too high and hence they are also considered as non-renewable.
Also renewable resources can be used again and again.
Hence, option D is correct

B) fossil fuels
C) water
D) minerals
Water is a renewable resource used for human needs. So, the correct option is C.
What are Renewable resources?Natural resources that regenerate with time and can be used endlessly without getting exhausted are known as renewable resources. These resources are often derived from sources such as sunlight, wind, water and biomass that can regenerate or replenish themselves.
Because they provide a source of energy and materials that can be used without negatively impacting the environment or depleting resources, renewable resources are an important component of sustainable development. Water is a renewable resource used for human needs.
Renewable resources are becoming more and more important as a sustainable alternative to non-renewable resources such as fossil fuels, which are limited and can adversely affect the environment.
