Explanation:
nonliving characteristics include the fact that they are not cells have no cytoplasm or cellular organelles and carry out no metabolism on their own and therefore must replicate using the host cell's metabolic machinery. And viruses can infect animals, plants and even other microorganisms.
Answer:
1. Gibberellins
2. Abscisic acid
3. Cytokinins
4. Ethylene
5. Auxins
Explanation:
Hormones, generally, are chemicals produced in a specific part of an organism in order to bring about a physiological change in another part. Hormones produced by plants are classified into the following: Auxins, Gibberellins, Cytokinins, Ethylene, and Abscisic acid. They effect the following major functions in plants:
- Gibberellins: These are hormones produced by plants that stimulate stem elongation, seed germination, and flowering.
- Abscisic acid: These are hormones that regulates survival functions of a plant such as the opening and closing of stomata.
- Cytokinins: These are chemicals/hormones that helps plant cells divide.
- Ethylene: These are hormones that promotes ripening of fruit or blooming of flowers.
- Auxins: These are chemicals or hormones produced in plants that are characterized by their ability to induce cell elongation and cell division in stems.
Answer:
A population changes in response to a change in the environment.
Explanation:
The changes in a population( variations) are due to changes in the environment. These variations confers an advantage to those individual possessing them. This enables such individuals to stand a better chance to survive in the struggle for existence. The better adapted individuals are able to survive and reach the reproductive age and pass over their favourable traits to their offspring.
Answer:
The answer is "PK1 activates PK2"
Explanation:
All enzymes were required again for the transmission of a signal. If Pk1 is continuously active, pk2 will no longer be required, as per my theory, can trigger pk1, therefore the cells were if they amplify the message even when they're not active. But since both enzymes require regular copies together for transduction, pk2 is simple and pk1 requires to also be activated.
There are 4 daughter cells after the process of mitosis.
