The importance of this compartmental arrangement is the fact that the mediastinum region of the body houses essential organs. The region contains the thymus, pericardial cavity, trachea, esophagus and major blood vessels. The separation provides these body parts with a barrier of tissues. The mediastinum also separates one lung from the other. This is functionally important as it allows one lung to work independently of the other in cases where one may be diseased or injured.
Answer:
The diagram is not attached but the question can be solved with the question alone, since the necessary information was provided.
• D. Offspring D (ff EE)
Explanation:
This is a cross involving two genes in mice. The two parents mice are crossed to produce four offsprings. The genotypes of the parents mice are FFEe (black fur) and ffEe (white fur).
These two parents will produce the following allelic combinations of gametes;
FFEe- FE, Fe, FE, Fe
ffEe- fE, fe, fE, Fe
Using these gametes in a pumnet square (see attached image), 16 possible offsprings will be produced with only three (3) distinct genotypes viz:
FfEE (4/16)
FfEe (8/16)
Ffee (4/16)
Hence, based on this question, all of the offsprings except offspring D (ffEE) is likely to be produced. This means that the offspring with genotype ffEE is the imposter as the parents mice with genotypes FFEe and ffEe could not have given birth to such offspring.
Answer:
Evolution or Adaptation
Explanation:
Because of the available food in the environment, such as big or small, hard or soft seeds based on the weather and the plant's production, the birds have to adapt to be able to consume their new type of food available, if a bird with a small beak tried to eat a large hard seed, it wouldn't be able to, or if a bird with a big beak tried to eat a small seed, it probably wouldn't be enough
A bullfrog is a sign of a healthy ecosystem. If you hear bullfrogs where you are fishing, you are in a healthy ecosystem. There are fewer frogs today than there was like 20 years ago
