The Smith family is afflicted with a genetic disorder known as Pinocchio nose syndrome, which causes affected adults to grow noses in excess of five inches long. 100 members of the Smith family show up for a family reunion. Of the fifty-three women, thirty-seven have unusually large noses. Of the forty-seven men, thirty-six have an enormous nose. Based on these figures, Pinocchio nose syndrome is probablyA)88dominant and sex-linked.
B) recessive and sex-linked.
C) dominant, but not sex-linked.
Eliminate
D) recessive, but not sex-linked.

Answers

Answer 1

Answer: The answer is letter B.

Since both sexes in the family are affected of the syndrome, it is considered as a recessive and sex-linked genetic trait. This simply means that the disease was passed down through families through one of the X or Y chromosomes (sex chromosomes). This occurs even if one parent has a normal gene but the other has an abnormal gene that carries the disease, the abnormal gene then dominates.

Answer 2

Answer:

Answer:

dominant, but not sex linked

Varicose veins seen in the superficial veins of the legs are unsightly and are often treated by surgical removal. However, even without these veins being present, the return of all blood toward the heart from the legs is not diminished. This is primarily because ______. the precapillary sphincters will contract to prevent blood from flowing toward areas where veins have been removed blood can still return via the deep veins in the absence of the venous valves (that have been removed), the blood will backflow into the capillary beds and then flow into other venules All of the listed responses are correct.

Explain how organisms changes within an environment affect their survival. Specifically discuss the effects of a gene mutation for color in beetles.

Answers

Animals gradually adapt to changes within their environment over time. This gives them a better chance of surviving rather than going extinct because of the change. Say there is a gene mutation affecting color within a population of beetles in a rain-forest. All of the beetles used to be red, but now a few of them have experienced a gene mutation and are green. Because they live in a rain-forest, it is likely that the green beetles would blend in with their surroundings far better than the original red beetles, and those red beetles would be wiped out by predators because they are easier to spot. The green beetles would live on and flourish, and their population would increase. Soon there would be few or none red beetles, and many green beetles.

Answer:

gene mutations help them camaflauge for survival. when change happens in an enviornment many things within the beetles mutation will change to adapt for the enviornment around them.

those genes will be passed down to the next generation survival of the fitest

Why do mushrooms sometimes appear after lightning?

Answers

Explanation:

Mushrooms can sometimes appear after lightning or thunderstorms due to several factors:

1. **Rainfall**: Lightning storms are often accompanied by heavy rainfall. Mushrooms, like many fungi, thrive in moist conditions. The rainwater provides the necessary moisture for mushroom spores that may have been present in the soil to germinate and grow.

2. **Nutrient Release**: Lightning can also influence the availability of nutrients in the soil. When lightning strikes the ground, it can release nitrogen from the atmosphere, which may then be deposited in the soil as nitrates. Nitrogen is an essential nutrient for all plants, including mushrooms. The increased availability of nitrogen in the soil can promote mushroom growth.

3. **Disturbed Soil**: The energy from lightning strikes can physically disturb the soil. This disturbance can unearth mushroom spores that were previously buried deeper in the soil, allowing them to come to the surface and grow into visible mushrooms.

4. **Warmth and Humidity**: Thunderstorms often bring warmth and humidity to the environment. These conditions are conducive to mushroom growth, as many mushroom species prefer warm, damp conditions.

It's worth noting that mushrooms are a diverse group of fungi, and not all species will appear after lightning storms. However, for certain mushroom species and under the right environmental conditions, lightning and accompanying factors can contribute to their growth and emergence.

Cyanobacteria, unusual worm like life-forms and marine organisms did not exist in Precambrian Time.

Answers

The statement is False.

Precambrian Time spans from about 4.6 billion years ago to about 540 million years ago. Fossils of some bacteria and cyanobacteria are an evidence that the life existed in Precambrian Time. They were the first organism that showed about 3.5 billion years ago. These unicellular organisms lived in the oceans. The first multicellular organisms evolved many years later, around 700 million years ago. Some fossils suggest the presence of some jellyfishes and worm-like forms that lived in the oceans. The land was not settled in the Precambrian time.

False
