Answer:
Pleiotropy
Explanation:
Pleiotropy is a genetic condition in which a single gene conditions the expression of multiple phenotype. There are different types of pleiotropy depending on the underlining mechanism
- <em>gene pleiotropy</em>
- <em>developmental pleiotropy</em>
- <em>selectional pleiotropy</em>
- <em>antagonistic pleiotropy </em>
<em>Phenylketonuria is a disease characterized by increased level of amino acid phenylalanine in the blood. It caused by mutation to the gene responsible for breaking down phenylalanine in the blood. Elevated level of phenylalanine causes other issues such as mental problems, urine coloration and reduction in skin pigmentation. This is a clear case of pleiotropy.</em>
Insects (Insecta) are the most diverse of all animal groups. There are more species of insects that there are species of all other animals combined. Their numbers are nothing less than remarkable, both in terms of how many individual insects, as well as many species of insects that are. In fact, there are many insects that is not very known how to count them all, the best thing we can do is to make calculations.
Approximate scientists who can be as many as 30 million species of insects alive today. To date, they have identified over 1 million. At any time, the number of live insects on our planet is amazingly, some scientists estimate that for every human being alive today, there are 200 million insects.
The success of insects as a group is also reflected in the diversity of habitats in which they live. Insects are more numerous in the land such as deserts, forests and grassland environments. They are also numerous fresh water such as ponds, lakes, streams and wetlands habitats. Insects are relatively scarce in habitats marine, but are more common in the waters brackish, like marshes and mangrove
Good luck!
Answer:
<u>Two different alleles come together and produce both trait forms</u>. Two different alleles come together and produce a trait form that is neither dominant nor recessive. a chromosome that determines the X or Y of an organism.
Answer:
Mitochondria is known as the powerhouse of the cell as it provides energy to the cell for performing different functions.
If a toxin causes pore in the inner membrane of the mitochondria and increases the permeability of the mitochondrial membranes. The permeability of mitochondrial membranes leads to mitochondrial swelling and causes cell death through necrosis and apoptosis.
The dependent variable in the experiment is the timing of a cricket's chirps. Thus, the answer is letter C. This variable is dependent on the temperature of the box in which the cricket was placed. The students want to know the relationship between this two variables.
