A researcher attempts to use a segment of ribosomal RNA as a molecular clock to calculate the date of the last common ancestor of two species. He finds that the two species diverged from a common ancestor 150 million years ago. These particular species have abundant fossil records that strongly suggest that these species diverged 100 million years ago. Which of the following answer choices best describes a reason for the discrepancy in the date of the last common ancestor of these species?

A. Ribosomal RNA is not a reliable molecular clock and should not be used for dating.
B. The neutral mutation rate used in calculating the last common ancestor date may not have been accurate.
C. It is highly likely that the two organisms did not share a common ancestor, so the results are invalid.
D. A large portion of the ribosomal RNA is not vital to survival, so it is not likely to be well preserved.

Answers

Answer:

B

Explanation:

It is B because the mutation rate should not have been accurate if it showes that they diverged 150 million years ago. But the abundant fossil records show that it diverged 100 million years ago.

A molecular clock estimates how long it has been since similar species separated from a common ancestor based on DNA sequences (or the amino acid sequence of proteins encoded by DNA).

Which of these is true of fetal development by the end of the third trimester?
A. The placenta is absorbed by the uterus.

B. The fetus can survive outside the uterus.

c. All development is complete.

D. All growth is complete.

Answers

Answer:

B. The fetus can survive outside the uterus.

Explanation:

The third trimester starts in the wekk 28 (month 7 ) of fetal development and lasts until the birth pf baby, that is around week 40 (month 9) of pregnancy.

There are several changes occur in the thrid trimester of the fetal development such as hearing and visual has developed and the internal organs  including the heart, lungs, intestines and stomach has developed enough.

So, at the end of fetal development of the third trimester as all the body organs have grown and developed, a fetus can survive outside the uterus.

The correct option is B.

Answer:

Option B

Explanation:

During the third trimester, the fetus continues to grow in weight and size however the body systems finish maturing. In fact, both mother’s  body and the fetus continue to grow and change. Lungs, brain and kidneys keep maturing. Fetus position itself head-down and is 6 to 9 pounds in weight. Skull bones are soft but fetus become able to suck its thumb and cry. By 38 to 40 weeks, the lungs have matured fully . The end of third trimester marks the period when the fetus is ready for delivery. Hence option B is the correct answer

A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots is most likely in Hardy-Weinberg equilibrium.

What do you mean by Hardy-Weinberg equilibrium?

The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.

Explanation:

Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.

In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.

Can readily transport nutrients from rock to aquatic ecosystems. Runoff that carries excess nutrients can cause algae blooms.The effects of soil erosion. Thus, option B is correct.

What is soil erosion?

The removal of the top of the soil by water, wind and human activities has been called soil erosion. The reason due to which soil erosion takes [place is that trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind. Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.

Soil erosion has happens when the dirt has been exposed to the high winds, heavy rains, and rushing water. In few circumstances, human activities, like farming and land clearance, expose soil to erosion. Soil erosion has been considered as the removal and transfer of the top layer of soil from its original location to another due to high winds and fast-running precipitation.

Therefore, Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.

In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.
