Answer:

Reproducing is fast for some animals, but can mess up their DNA and genetics. Humans and other aninkas take a while. It has a better chance of perfect genetics and heredity from parent, this goes along with sexual and asexual reproduction.

Describes three types of stimuli that cause plants to exhibit tropism.
I am Lyosha [343]

Answer:

The three stimuli that cause the plants to exhibit tropism are:

1. Touch: This stimulus triggers thigmotropism, which is the turning or bending of the plant and tendrils in response to the touch.

2. Light: This stimulus triggers phototropism. It is how the plant reacts toward the direction of the light source. In this case, the stem may bend in response to the direction of the light.

3. Gravity: This stimulus triggers phototropism gravitropism, which is responsible for the downward growth of roots into the soil.

The practice of leaving crop residue on the field between plantings to help prevent soil erosion is known as
Advocard [28]

The practice of leaving crop residues on the field in between planting seasons is known as conservation tillage.

<h3>Conservation tillage</h3>

Some soils are prone to erosion once they are directly exposed to the impact of precipitation.

After harvesting crops from a field, the crop residues are left on the field to prevent the direct impact of precipitation in cause erosion. The crop residue, in addition, adds to the organic matter of the soil after their decomposition.

Such a practice is known as conservation tillage.

How many dna molecules are present in your diploid cells
Tcecarenko [31]

Answer:

92 molecules

Explanation:

DNA or Deoxyribosenucleic acid is polynucleotide made up of several nucleotides containing the genetic information of an organism. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA, tightly coiled many times around proteins called histones to support its stucture.

Human cells, like myself, contains 23 pairs of chromosomes (46 chromosomes in total). Each pair coming from each parent. Each chromosome is formed by two strands of DNA held together by hydrogen bonds forming the DNA double-helical structure. These two DNA strands form a base pair, which is a unit of two nucleotide bases bound to each other by hydrogen bonds. According to the complementary base pairing rule, Adenine (A) pairs with Thymine (T) while Guanine pairs with Cytosine (C).

Since there are 46 chromosomes in a diploid human cell and each chromosome consists of 2 DNA strands, then, there are 46 × 2 = 92 strands/molecules of DNA in each human diploid cell.
