Answer:
The correct answer is D. is a facultative anaerobe
Explanation:
A facultative anaerobe is the organisms that can live in the absence of oxygen but prefer to utilize the oxygen when oxygen is present in the environment.
An anaerobic organism requires more amount of energy sources like carbohydrates because they use the fermentation process to make energy and this process results in the formation of less energy than aerobic respiration.
All the bacteria of family Enterobacteriaceae that live in the intestine are facultative anaerobes. Therefore facultative anaerobe can thrive in both the presence and absence of oxygen so the correct answer is D. is a facultative anaerobe.
Answer:
Tt and tt
Explanation:
To solve this just work backwards. The first box has Tt so one parent has to have T and the other t. Since the tall plant is on the top, it is T_ and t_. Next use the second box (tt). They are both t so the final answer is Tt x tt.
Diploid cells. Meiosis is the process of cell division by
which involving gametes. Cell division is just the same for sperm and egg
cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis
is for the males’ sperm cells and oogenesis is the process for females’ egg
cells. The cell division of meiosis involves the two phases, respectively
meiosis I and meiosis II. Meiosis I like mitosis is the cell division that
produces diploid cells. These diploid cells are cells that contain a complete
pair of chromosomes which is 46. The result is two diploid cells after the
first meiosis. To provide clear explanation, in contrast haploid cells only
contain 23 chromosomes and are created after meiosis II which is 4 in number.
Answer:
Arteries carry blood away from the heart
Explanation:
Veins carry the blood back to the heart.

1. The oxygen requirements of an animal cannot be met by the process of diffusion as diffusion is a very slow process. To overcome this, multicellular organisms have specialized cells and tissues for performing various necessary functions of the body such as intake of oxygen and food.
2. What criteria do we use to decide whether something is alive? Any visible movement such as walking, breathing, or growing is generally used to decide whether something is alive or not. However, a living organism can also have movements, which are not visible to the naked eye.
3. An organism uses outside raw materials mostly in the form of food and oxygen. The raw materials required by an organism can be quite varied depending on the complexity of the organism and its environment.
4. The various processes essential for maintaining life are nutrition, respiration, transportation, excretion, control and coordination.
