You cross two red griffins with blue eyes and produce offspring that are: red with blue eyes, red with green eyes, white with bl
sergejj [24]

Answer:

The reason for the offspring to present these genotypes is that during the formation of the gametes, the alleles separate and are inherited independently, therefore they can generate several different phenotypic combinations.

Explanation:

In order for an offspring to present very different phenotypes, as shown in the question above, it is necessary that the two red griffins with blue eyes that were crossed are heterozygous. Thus it will be possible for the offspring to present a wide variety of phenotype, according to Mendel's second law.

Mendel's second law is called the Law of segregation. This law explains that the alleles (which determine the characteristics of individuals) are separated in the formation of gametes and inherited by the offspring of a cross independently, and can generate different combinations of phenotypes, when the parents of a cross are heterozygous.

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.

ad-work [718]

Answer;

D. Meiosis ii of mother

Explanation;

-The non-disjunction occurs in the meiosis II of the mother. This non-disjunction occurs when the two sister chromatids X and X fails to separate during meiosis II and produces an egg having two X chromosomes.

-Klinefelter syndrome is a condition that occurs in males when they have an extra X chromosome. The syndrome is not inherited, but usually occurs as a random event during the formation of reproductive cells (eggs and sperm) that results in the presence of one extra copy of the X chromosome in each cell (47,XXY).
