The ability for people to roll their tongue is dominant to people who cannot. If a tongue roller and a non-tongue roller were crossed, the highest percentage of potential non-tongue roller offspring would be which of the following?

Answers

Answer:

50%

Explanation:

Tounge rolling is a dominate trait, so that means it would have to have at least 1 captial letter in it't genotype (assuming captial letters refer to the dominate trait). But, because the demonate trait covers any non-dominate traits, you can have a lower case letter in the genotype while still having someone be a tounge roller (assuming lower case letters are non-dominate traits)

Because non-tounge rollers are non-dominate, they must have two lower case letters in their genotype.

This leaves you with the two genotypes of :

AA or Aa (tounge rollers)

aa (non-tounge rollers)

When crossing AA with aa in a punette, every outcome is Aa. This leaves you with no potentional non-tounge rollers. But, you can still cross Aa with aa, because as said before Aa has a dominate gene, so it would result in someone with the tounge rolling ability.

When crossing Aa and aa in a punnet sqaure, you can get outcomes. Aa or aa. 2 of teh 4 options are Aa, and 2 of teh four options are aa. This means half, or 50% of the offspring are predicted to be non-tounge rollers, showing the high ercentage must be 50%.

A suggested and testable explanation for an event is called a ________.

Answers

Answer:

Hypothesis.

Explanation:

A hypothesis is a testable explanation for an event. For example, if you see a certain type of bird at your bird feeder, but never your neighbor's, you could come up with the hypothesis that that specific species of bird likes something that is present in your own birdseed, but not your neighbor's. This is easily testable by switching out different birdseeds and seeing which ones attract the birds, and serves to explain why the birds only appear at your bird feeder.

Yolk sac is a structure that has a short duration in intrauterine development and is an important site for early blood cell formation.

What is the yolk sac?

It is the bag that houses yolk inside and that allows the embryos of certain species to feed in the initial stages of development.

Due to this structure, the embryo receives oxygen and nutrients and can discard its waste, in the case of the human being, the yolk sac fulfills the functions of the circulatory system, until the internal circulation begins to develop.

Therefore, we can conclude that the yolk sac is a structure that has a short duration in intrauterine development and is an important site for early blood cell formation.

How does the human immune system initially respond to a pathogen?

Antibiotics are released by B cells to destroy the pathogen.
B cells release vaccines to destroy the incoming pathogen.
Lymphocytes recognize pathogens as antigens in the body.
T cells build immunity to the pathogen by releasing antibodies.

Answers

Answer:The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies. Antibodies attach to an antigen and attract cells that will engulf and destroy the pathogen.

Explanation:

Antibiotics are released by B cells to destroy the pathogen. The correct option is A.

What are antibodies?

Proteins called antibodies defend you when your body comes into contact with an unwelcome chemical.

Antibodies, which are made by your immune system, bind to these foreign chemicals and drive them out of your body. Immunoglobulin is another name for an antibody.

Proteins called antibodies are created by the immune system in response to infection.

They play a crucial role in the body's defense mechanism because they work to eliminate pathogenic organisms and prevent them from invading human cells.

In response to antigens, the immune system either produces cells that go after the pathogen directly or produces specialized proteins known as antibodies.

Antibodies draw cells that will engulf and eliminate the infection by binding to an antigen. B cells and T cells, two types of lymphocytes, are the immune system's primary cells.

Thus, the correct option is A.
