Tall plants are dominant over short plants. One parent is homozygous dominant and the other is heterozygous for plant height.
Greeley [361]

Answer:

a. all tall

Explanation:

If genotypically one of the parents is homozygous dominant and another one is heterozygous for plant height then phenotypically all their progeny will be tall.

Let us suppose, 'T' represents dominant allele and 't' represents recessive allele. Then the genotype of one parent who is homozygous dominant will be TT and genotype of another parent  who is heterozygous will be Tt.

The cross is depicted in the attachment.

Here it may also be noted that genotypically two of the progeny will be homozygous dominant while two of the progeny will be heterozygous but phenotypically all the progeny will be 'tall'.

Describe the view if you were to stand in the penumbra of a lunar eclipse.
madreJ [45]

From within the Moon's penumbra, a partial solar eclipse can be seen. Like any other opaque objects illuminated by a light source, the Moon and the Earth cast shadows into space as they block the sunlight that hits them. Each shadow has 3 different areas: the umbra, the penumbra, and the antumbra.

Speckled trout and red drum both prey on mullet along the Texas coastline. Dead zones are caused by excessive nutrient pollution
AleksAgata [21]

Answer:

All Three Populations Would Decrease

Explanation:

Dead zones have little to no life in them, and besides the fact that this would mean the popoulations of all of them would just be down because of this, mullet will die out due to nothing to feed on, which will make drums and trout also die out, so all of the populations would go down.

matrenka [14]

Answer:

While hiking, you must push aside thick branches that are near your face. One of them rips the skin on your arm and you begin to bleed from the cut. Which of the following plays an important role in initially protecting you from infection?

The answer to the question is option D (barriers such as dead skin cells and mucus because they are part of the innate immune system)

Explanation:

Hiking which is a way to stay physically active can simply be explained as an engage in a leisure-like activity, to walk a long distance or for exercise.

Innate immunity is one of the two main immunity strategies found in vertebrates, is composed of physical, chemical and cellular defenses against pathogens,  such as skin, chemicals in the blood, and immune system cells that attack foreign cells in the body immediately or within hours of an antigen's appearance in the body.

The innate immune system relies on the recognition of particular types of molecules that are common to many pathogens but are absent in the host.

Innate immunity, is something already present in the body which is activated against a specific type of antigen, and the immunity remains throughout the life.

An example of Innate immunity, is the white blood cells fighting bacteria.

Innate Immunity action is usually rapid, and the first line of defense against non-self pathogens is the innate immune response.

Innate type of immunity is generally inherited from parents and passed to offspring.

The main purpose of the innate immune response is to immediately prevent the spread and movement of foreign pathogens throughout the body.

Therefore, during the first critical hours and days of exposure to a new pathogen, the body rely on the innate immune system to protect it from infection.

The skin and other epithelial surfaces, provide a physical barrier between the inside of the body and the outside world.

The mucus layer also contains substances that kill pathogens or inhibit their growth.

Microorganisms do occasionally breach the epithelial barricades. It is then the innate immune system that recognizes and destroy them, without harming the host.
