When Mendel crossed purple flowered pea plants with white flowered plants of the P generation what was the phenotypic ratio of the offspring?

Answers

Answer 1

homologous chromosomal pairs segregating separately during anaphase I. Mendel occasionally achieved a 3:1 phenotypic ratio by crossing two purple-flowered pea plants.

Segregation meant what, exactly?

Segregation is the separation of individuals, historically based on race and/or gender. Segregation implies that people are physically separated in daily life, the workplace, and the enjoyment of civil rights.

Why is segregation problematic and what does it entail?

Violence is more likely in certain neighborhoods because of residential segregation, which concentrates social and economic issues there. According to a recent study, areas with high levels of residential segregation may not be as prosperous as the rest of the area since those areas see slower increases in income and property values.

1.Consider the model above compare the DNA sequence of the model and abnormal CFTR gene explain the differences and similarities between the two.
2. Explain what caused the abnormal structure of CFTR protein.
3. Considering the structure of the mutant protein channel do you think it can perform the same function as a normal CFTR protein channel explain why or why not?

Answers

Answer:

1.Their similarities are that they both contain the codons for the following amino acids Isoleucine (ATC), glycine (GGT) and valine (GTT).

Their differences are:

a. Their codons for the second isoleucine molecule is different, ATC in the normalgene compared to ATTinnthe abnormal gene.

b. The codon for the amino acid phenylalanine is lacking in the abnormal gene.

2. The abnormal structure of the CFTR protein is because the amino acid phenylalanine is lacking in the polypeptide chain of the that region of the protein. This would result in an error in the secondary and tertiary structure of the protein.

3. The mutant protein would not be able to perform its function of channelling chloride ions across the membranes because the protein molecule is not properly folded for this function.

When resistant bacteria multiply, what do they pass on to the next generation?

Answers

Answer:

Antibiotic use promotes development of antibiotic-resistant bacteria. Every time a person takes antibiotics, sensitive bacteria are killed, but resistant germs may be left to grow and multiply. Repeated and improper uses of antibiotics are primary causes of the increase in drug-resistant bacteria.

The resistant bacteria can reproduce rapidly because their competition (the non-resistant bacteria) has been destroyed by the antibiotic. When the resistant bacteria reproduce, they produce genetically-identical copies. These copies will all be resistant to the antibiotics.

rainfall. A farmer notices that a well on the farm stops providing water
during a drought. A nearby lake also
has less water in it than usual. Write a
couple of sentences that explains
what has happened to the water table
in the area to cause these results.

Answers

Due to the heat of the drought, the water goes through the process of evaporation which turns to a gas or vapor causing less water

In the drought period, the water label usually lowers due to the extreme heat of the sun that forces the water to undergo the process of evaporation and absorb all the water present on the surface.

What is drought?

Drought may be defined as a brief period of abnormally dry weather sufficiently prolonged for the lack of water to cause a serious hydrologic imbalance in the affected area.

During severe droughts, people depend heavily on groundwater—the water held underground in aquifers. During these periods, the rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth of water in wells gradually increases.

Therefore, in the drought period, the water label usually lowers due to the extreme heat of the sun that forces the water to undergo the process of evaporation and absorb all the water present on the surface.

Studies have shown that children are especially vulnerable to the effects of ultraviolet (UV) radiation. Tanning beds expose the skin to nearly ten times as much UV radiation as natural sunlight. With that knowledge, a law was passed in some states to prevent individuals under the age of 18 from using tanning beds. Which statement best explains why UV radiation is so harmful?
a) It can increase harmful DNA mutations in cells.

b) Diseases are all caused by exposure to environmental factors.

c) Homeostasis in an organism is increased by the presence of UV radiation.

d)UV Radiation decreases the likelihood that mutations will occur.

Answers

Hello there!!

The answer, I think, would be A.

UV radiation can create problems in the correctness of cell replication, which can result in mutated cells.

I hope this answers your question!

Tanning beds can increase harmful DNA mutations in cells. So, the correct option is A.

What are Tanning beds?

In order to tan individuals, a tanning bed emits UV radiation (make their skin darker). If someone spends too much time in the tanning bed, it can also burn their skin, much like the sun. Many types of tanning beds exist. Using tanning beds can lead to more damaging DNA alterations in cells.

Special fluorescent lights (16–32 per tanning bed) that produce both visible and UV light are used in tanning beds. They employ a ballast system, like all fluorescent lights, to keep the amount of electricity going to each lamp to a maximum of 100 watts per lamp. A specific acrylic, or clear shield, is used over the bulbs in tanning beds.

Therefore, the correct option is A.

For many years, scientists thought that the universe was static—that it had always existed and been the same, and it was neither expanding nor contracting. Then, in the late 1920s, Edwin Hubble recognized that the shift in light from distant objects toward the red end of the spectrum meant that those objects were moving away from Earth. The best explanation for these observations was that the universe was not static but was expanding. More recent observations, such as cosmic background radiation, are also better explained by an expanding universe rather than a static universe. What aspect of scientific methodology best explains the replacement of the static universe theory with the expanding universe theory?
A Science and its methods are always improving. Scientists needed newer, more sensitive instruments to detect the slow expansion of the universe.

B Hubble’s observations were extremely popular with the public, leading to overwhelming support for the new theory.

C The new theory explained Hubble’s observations, and it was tested and supported by additional observations. The theory was accepted because it was the most powerful explanation available for many observations.

D The natural progression of science is that all theories are eventually replaced by new theories until one is established as law

Answers

Answer:

C

Explanation:

B has nothing to do with the scientific method. The public does not determine a scientific law. Facts do.

D may be sort of true, but it does not explain Hubble's process. Nor does it explain what Hubble actually did and how he reported it. D is incorrect.

A was never implied (although it is likely true. On the other hand, many great scientific principles are uncovered with very simple apparatus.) A might be 1/2 true.

I think the best answer is C. It is general enough to be accepted. There are two theories mentioned. So C is the best answer.
