The number of people who are carriers (heterozygous) for PKU if there are 33 of the 300,000 people in Corpus Christi, TX, have PKU is 15. Heterozygous or also called as zygosity refers to having the unlike genes or different genes.
Working in a lab means working under controlled environment. If in the generation 1 and generation 3, the number of bird’s increases or decreases in number, the possible conditions for this would
- The amount of food increased or decreased
- If a flock’s beak type made it easier to pick up the available food, the flock grows and vice versa
Justification: if the beak type for generation 1 makes the food intake easier, it will grow which ultimately decreases the food for the generation 3 which has un-supportive beak type.
Answer: your answer is A
Explanation: they are made of one or more cells :)
Answer:
<em>B: The drug is a small charged molecule</em>
Explanation:
Substances can passively diffuse in and out of the cell via the cell membrane in two ways;
- Simple diffusion
- Facilitated diffusion
The cell membrane allows small molecules or ions to freely diffuse across it in response to concentration difference between the inner and outer parts of the cell membrane. This is known as simple diffusion.
In facilitated diffusion, special proteins in the cell membrane, known as channel/carrier proteins binds with molecules and facilitates their diffusion across the cell membrane by carrying them through special channels in the membrane.
Hence, to support the alternative hypothesis that the new drug will exhibit simple diffusion across the plasma membrane, the drug should be a small charged molecule.
<em>Correct option: B</em>
