Do you expect to find more or less variation in a population with short coalescence times relative to a population with long coalescent times? Explain your answer.

Answers

The coalescent time is the point in the past at which two lineages within a population merge into a common ancestor.

A population with short coalescence times would have experienced fewer generations since its most recent common ancestor, resulting in less time for genetic variation to accumulate. As a result, we would expect to find less variation in such a population.

Conversely, a population with long coalescence times would have experienced more generations since its most recent common ancestor, resulting in more time for genetic variation to accumulate. Therefore, we would expect to find more variation in such a population.

In summary, coalescence time can have a significant impact on genetic variation within a population.

Answers

C, ribosomes make protein and Golgi bodies are the ones who store them

The proteins that are generated by the ribosomes are stored in the Golgi apparatus.

What is the Golgi apparatus?

Golgi apparatus is also called the Golgi complex or Golgi body. It is a membrane-bound organelle present in eukaryotic cells. It is made from a network of flattened stacked structures called cisternae.

The Golgi apparatus is responsible for the transportation, modification, and packaging of the proteins and lipids molecules into small vesicles. These vesicles are delivered to their destinations.

This organelle is embedded in the cytoplasm right after the endoplasmic reticulum. It is located near the cell nucleus. These are present in hundreds of plant cells.

They help in the transport of secretory proteins, cell membrane proteins, lysosomal proteins, glycoproteins etc. They also help transport some glycolipids. Much of the material for the cell wall passes through the Golgi apparatus.

Therefore, the Golgi apparatus helps in protein packaging.

Why might there be a competitive advantage to having a different flight initiation distance

when a bird is incubating eggs

Answers

Answer: The birds can perceive any kind of danger which can harm the eggs after laying.

Explanation:

The birds show response towards the other stimulus around them like weather conditions like excessive heat and rain and predators. Also they can sense the danger of damage to eggs by fellow members of the species. The distance at which the birds fly from the danger is the flight initiation distance. It is the separation distance from any kind of danger or disturbance and birds cross this distance before incubating their eggs. This is an competitive advantage with that of other members of the species as the bird will able to give birth to new ones and its population will increase in number, so the chances of reproduction and survival increases in this case.

HELP ME PLEASE! List the steps scientists for using technology to find the half-life of an isotope.​

Answers

For radioactive materials with short half-lives, you use a very sensitive calibrated detector to measure how many counts per second it is producing. Then using the exact same set up you do the same at a latter time. You use the two readings and the time between them to determine the half-life. You don’t have to wait exactly a half-life, you can do the math with any significant time difference. Also, you don’t need to know the absolute radioactivity, as long as the set up is the same you only need to know fraction by which it changed.

For radioactive materials with long half-lives that won’t work. Instead you approach the problem differently. You precisely measure the mass of a very pure sample of the radioactive material. You can use that to calculate the number of atoms in the sample. Then you put the sample in a counter that is calibrated to determine the absolute number of disintegrations happening in a given time. Now you know how many of them are disintegrating every second. You use the following equations:

Decays per Second = (Number of Atoms) x (Decay Constant)

Half-life = (Natural Log of 2) / (Decay Constant)

And you can calculate the half-life

Given the following pedigree: What is (are) the possible mode(s) of inheritance? I. Autosomal dominant II. Autosomal recessive III. X-linked dominant IV. X-linked recessive (question 25 of 2005 exam)

Answers

Based on the information given in the pedigree, we can make the following observations:

The trait appears in every generation, which suggests that it is not X-linked recessive, as this would skip generations if the affected individual is a female.

The trait is seen in both males and females, which rules out X-linked dominant, as this would only affect females (since males inherit only one X chromosome from their mother).

The trait is seen in offspring of affected parents, which suggests that it is not autosomal recessive, as this would require both parents to be carriers of the trait.

The trait does not affect every individual in a generation, which suggests that it is not autosomal dominant, as this would result in all offspring of an affected parent being affected as well.

Based on these observations, the possible mode of inheritance for this trait is X-linked recessive or autosomal recessive (if both parents are carriers). However, without more information, it is difficult to determine the exact mode of inheritance.

This means that the animal should be moved to a habitat that has similar temperatures, precipitation levels, soil type, light conditions, and other abiotic factors to its current habitat in Century National Park. Additionally, the new habitat should have similar food sources, predators, and other animals that the animal interacts with in its current habitat.

If the new habitat is significantly different from the current habitat, the animal may have difficulty adapting and surviving, which can lead to population declines and even extinction.
