Cells starting mitosis and meiosis begin with what set of chromosomes. True or False
Arisa [49]

Answer:

with haploid or diploid set of chromosomes. True

Explanation:

There are two types of cells in the body, haploid cells and diploid cells. The biggest difference is related to the number of chromosomes that each cell contains, while diploid cells contain two chromosomes (2n), haploid cells contain a chromosome (1n).

Features:

1. A haploid cell has only one set of chromosomes (n), while diploid cells have two sets of chromosomes (2n).

2. In humans, somatic cells are diploid, while gametes are haploid.

3. Diploid cells develop as a result of mitotic cell division, while haploid cells develop as a result of meiotic cell division.

4. Mitosis produces 2 identical daughter cells, where both stem and daughter cells are diploid. In meiosis, a diploid cell divides twice to produce 4 haploid daughter cells.

5. Humans and most animals are considered diploid organisms, while algae and fungi are examples of organisms that are haploid in most of their lives. Male bees, wasps and ants are also haploid.

In ________ conditioning, the unconditioned stimulus unconditionally elicits a reaction. For example, a bit of black pepper blow
kipiarov [429]

Answer:

The answer is: Classical Conditioning.

Explanation:

  • According to the theory of Classical Conditioning, an Unconditional Stimulus can be defined as such a stimulus that is capable of triggering a response spontaneously and naturally without the requirement of a previous learning or knowledge about the stimulus.
  • A Neutral stimulus can be defined as such a stimulus which is responsible for drawing or focusing the attention of a person to a particular event.
  • A Conditional Stimulus can be defined as such a stimulus which is generated due to the repeated integration of an Unconditional stimulus to a Neutral stimulus. The repeated integration eventually results in the generation of a conditioned response.
  • In the given example, a bit of black pepper blown into the eyes for the first time is an example of unconditional stimulus. This stimulus initiates a spontaneous or unconditional response, that is, blinking of eyes.
  • But, when this unconditional stimulus gets integrated to the neutral stimulus (irritation in the eyes draws the attention of the person) repeatedly, it can result in the generation of a Conditioned Response (blinking of eyes whenever any foreign object gets into it).
