Answer:

Humans and most mammals have two sex chromosomes, the X and Y. ... Egg cells all contain an X chromosome, while sperm cells contain an X or a Y chromosome. This arrangement means that during fertilization, it is the male that determines the sex of the offspring.

Answer:

Due to less number of chlorophyll.

Explanation:

The variegated  leaves accumulates or produces less amount of food than non-variegated leaves under similar condition​ because variegated  leaves has number of chlorophyll as compared to non-variegated  leaves. Chlorophyll is a green pigment that is responsible for the photosynthesis in plants, without chlorophyll no photosynthesis occurs in the plants. The variegated  leaves has less number of chlorophyll as compared to non-variegated  leaves which leads to less production of food in variegated  leaves.

Answer:

D. is not very significant because it gives us little insight into human behavior.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

As a scientific concept, race is not very significant because it gives us little insight into human behavior.

This ultimately implies that, race is a scientific concept that holds no significant or absolute value since the nineteenth century.

Hence, the difference between humans shouldn't be described based on race according to the United Nations Educational, Scientific and Cultural Organization (UNESCO).

Answer:

Nucleus, mitochondria, cell membrane, ribosome, golgi body

Explanation:

Answer:

they all come from the same ancestor, and all organisms have DNA made of the same molecules that form our genetic code. DNA in every organism has the bases: A,T,C,G.

Also, don't use this if it's still June 2021 and you're doing ap ex, we might have the same teacher.

All living organisms use the same genetic code. This shows that all organisms share a common evolutionary history.

The genetic code is the set of rules used by living cells to translate information encoded within genetic material into proteins. It is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.

Answer:

1 Vena cavae (vessels)

2 Right atrium (chamber)

3 Tricuspid valve (valve)

4 Right ventricule (chamber)

5 Pulmonary valve (valve)

6 Pulmonary artery (vessels)

7 Through the lungs (O2 picked up)

8 Pulmonary veins (vessels)

9 Left atrium (chamber)

10 Mitral valve (valve)

11 Left ventricle (chamber)

12 Aortic valve (valve)

13 Aorta (vessels)

14 Through the body (O2 released)

Explanation:

The oxygenated blood travels through the arteries distributing oxygen to the cells. Then the deoxygenated blood goes through the veins and to the heart and the lungs.

The deoxygenated blood enters the heart through the vena cavae. From there, it goes to the right atrium. The accumulation of blood in the right atrium opens the tricuspid valve, and the blood goes to the right ventricle. Between the right ventricle and the pulmonary vein, it is the pulmonary valve. The valve stops blood from going back to the ventricle once it is in the pulmonary artery. The pulmonary artery carries the blood to the pulmonary arterioles and these to the pulmonary capillaries, where the blood picks up oxygen and releases carbon dioxide. This process happens in the lungs.

Once that the blood has oxygen, it goes from the capillaries to the pulmonary venules. Then, to the pulmonary vein. The pulmonary vein brings the blood to the left atrium, then it goes through the mitral valve and flows to the left ventricle. Between the left ventricle and the aorta, it is the aortic valve. A valve that stops the blood from going back to the ventricle once it went to the aorta. From the aorta, the oxygenated blood goes to the rest of the body.

Answer:

Can result in a new variety of gene combinations in the species

Explanation:

The third option is blatantly untrue- gene mutations are sometimes harmful, usually mundane and do nothing, and sometimes extremely helpful.

The fourth option is also untrue- genetic mutation is completely random.

This leaves us with the first two-

The first option is true, but it's not why genetic mutations are important, it's simply how they are passed on.

The second option is the awnser because gene diversity is extremely important in populations, and 'variety of gene combinations' is just another way to say gene diversity.

Melanin

Explanation:

Melanin is the protective component of skin that defends us against UV light.

UV light poses big risks to our health, as it can damage DNA. DNA damage can lead to cancers like skin cancer.

Melanin is a pigment in the skin that protects us from UV light. This pigment blocks UV radiation from entering our skin and damaging our DNA.

So, the correct answer is melanin.

Answer:

1. melanin

2. moving away from the equator

3. the impact of UV radiation on folate and Vitamin D levels in human populations

Hope I helped :)

The factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection are the impact of UV radiation on folate and Vitamin D levels in human populations.

 Ultraviolet B radiation produces diet D in human skin. Ultraviolet radiation can, however, smash folate. Folate is critical for the speedy increase of cells, particularly at some point in which its deficiency can motivate neural tube defects. The human frame additionally has a mechanism to save you overproduction of vitamins.

Ultraviolet is a shape of electromagnetic radiation with a wavelength from 10 nm to four hundred nm, shorter than that of seen light, but longer than X-rays. UV radiation is found in sunlight and constitutes approximately 10% of the whole electromagnetic radiation output from the Sun.

Thus it is learned that the above answers are well-explained factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection bout.

D. Homeostasis

Explanation:

An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.

Basically, the endocrine system contributes significantly to the state of homeostasis in the body.

Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.

Hence, regulation of the internal body temperature of the bumblebee is an example of homeostasis.
