Answer:
A
Explanation:
<em>The active state of cell division covers the prophase, metaphase, anaphase, and telophase. The total number of observed cells that were undergoing cell division can, thus, be calculated by adding the number of cells in each stage of the cell division.</em>
Total number of cell in division = 20+4+2+4
= 30
Probability that a randomly chose cell will be undergoing cell division = <em>number of cells in division/total number of cells</em>
= 30/200
= 0.15 or 15%
The correct option is, therefore, A.
Answer:
Rate of cellular respiration is higher.
Explanation:
Photosynthesis is a process in which plants makes its food. This food is very significant for the plant and those who eats these plants. The factors which affect photosynthesis ,light intensity,carbon dioxide and temperature.
Light intensity: Without enough light plant cannot photosynthesize even there is plenty of carbon dioxide and temperature.
If there is no light the carbon dioxide uptake is below Zero(0) With no light there is no photosynthesis.So the rate of respiration higher than the photosynthesis.
If the light intensity increased the rate of photosynthesis will also be higher and more carbon dioxide uptake by the plant during photosynthesis
Nails are made of iron because, iron is strong and sturdy; although nail rust when it undergoes oxidation when expose to water but it is not explosive.
Barium and phosphorus are not suitable for nail making because of their properties.
Barium is an element which reacts with virtually all non metals, forming poisonous products which are dangerous to health and to the environment. It also reacts explosively with water.
Phosphorus is not found in its pure form in nature, it conducts electricity and it is combustible in nature.<span />
Answer:
pigs, badgers, bears, coatis, civets, hedgehogs, opossums, skunks, sloths, squirrels, raccoons, chipmunks, mice, and rats. The hominidae, including humans, chimpanzees, gorillas and orangutans are also omnivores.
Explanation:
The answer to this is protein.
Hydrochloric acid in digestive system is found in stomach, which is the only main digestive organ with an acidic pH 2.
In the stomach, only one kind of the primary food substance is chemically digested, which is protein. It is digested with the help of enzyme Pepsin, which breaks protein chains into polypeptides.
After that, the other organs of the digestive system has more of a neutral to slightly alkali condition, which is not related to hcl. Therefore, the answer is protein.
