Answer:

The best example of environmental influence that would most likely result in natural selection is that a food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.

Explanation:

Among the environmental factors that can influence natural selection at a given time is the availability of food. Natural selection, from the point of view of evolution, is influenced by adverse environmental conditions, being food shortage one of them.

In conditions of food shortage in a pond, as in the example of the frog population, only the most apt will be able to take advantage of nutritional resources, while the less apt will not be able to survive. The ability to survive with little food available becomes an inherited trait that will be passed on to future generations.

In any case, tolerance to adverse conditions becomes adaptation, which translates into survival and reproductive success.

The other options are not correct because none of them show environmental pressure that can lead to natural selection.

Traits are passed from parents to offspring. These traits are determined by

musickatia [10]

Answer:

The traits that are transferred from the parents to the offspring during reproduction are determined by genes, located on chromosomes, found in the nucleus.

Explanation:

During reproduction, there is a fusion of;

male gamete

female gamete

This leads to the formation of offspring. There is a transfer of traits from the parents to the offspring.

Hence, the traits that are transferred from the parents to the offspring during reproduction are determined by genes, located on chromosomes, found in the nucleus.

External ear structure that helps to localize the direction from which sound arises

Step2247 [10]

The external ear structure is called the Pinna.

The Pinna helps to channel sound waves into the ear.

Many animals have the ability to move their pinna towards the direction of sound.

I have attached an image of a dog's ear to show you the external structure called the Pinna.

I hope this helps! I'm happy to answer any other questions you might have :)

Which genotype determines that a person does NOT have sickle-cell anemia, but has the potential to pass the genetic disease on t

anyanavicka [17]

Answer:

The correct option is C) AS

Explanation:

Sickle cell anaemia is a recessive disorder in which the blood of the person is not able to clot properly. For sickle cell to occur, both the alleles for the trait have to be recessive. A person who has a dominant and a recessive allele will be heterozygous, showing the dominant characteristics. But such a person will be a carrier for the disease. There will be chances for the offsprings of that person to actually have the disease.

What can be interpreted about type 2 diabetes mellitus in monozygotic twins when it affects only one twin 70% of the time and af

Masja [62]

Answer:

The correct option is C. Non-genetic factors can influence expression.

Explanation:

Non- genetic factors can be described as factors other than genetic makeup. These factors include environmental factors and factors arising from the lifestyle of an organism.

Certain studies have shown that both the genetic as well as the non- genetic factors play a role in the development of certain characteristics.

In the above-mentioned scenario, both the monozygotic twins have diabetes but one of them is affected 70% of the time due to his lifestyle. The person might be consuming more sugars and alcohol.
