The process illustrated in the figure shows an increase in genetic variation.
The true choice is B
Genetic variation is a variation that occurs in the genome of an organism either in nucleotide bases, genes, or chromosomes. Genetic variation at the basic level is shown by differences in the base sequences of the nucleotides (adenine, thymine, guanine, and cytosine) that make up DNA in cells.
Genetic variation can be caused by several events, namely crossing over, conjugation, mutation, and fertilization. Genetic variation can be one of the factors that influence evolution.
Genetic variation is very influential in evolution because the greater the genetic variation in a population, the greater the chance for that population to adapt to environmental changes and disease.

How does genetic variability allow these lizard populations to survive ?
Answers
Starch is a complex carbohydrate that is digested by the enzyme amylase. A mutation in the gene that encodes amylase prevents the digestion of starch. The inability to digest starch is an autosomal recessive trait. In a population of 1000 flies, 410 were unable to break down starch. What is closest to the number of flies expected to be heterozygous for the amylase mutation assuming all conditions of Hardy-Weinberg equilibrium are met?
Answers
Answer:
The closest to the number of flies expected to be heterozygous for the amylase mutation assuming all conditions of Hardy-Weinberg equilibrium are met is 1600 flies.
Explanation:
According to the Hardy-Weinberg equation : p² + 2pq + q² = 1
Also p + q = 1
Where p² is the frequency of individual flies with the similar alleles for the dominant trait;
2pq is the frequency of individuals with the heterozygous allele for breaking down starch, while q² is the frequency of the individuals having similar allele formthenrecessive trait.
q² = 410/10000 = 0.041
q = 0.2
p = 1 - 0.2
p = 0.8 p² = 0.8²
p² = 0.64
2pq = 1 - 0.2 - 0.64 = 0.16
2pq = 0.16 × 10000
2pq = 1600
Therefore, the closest to the number of flies expected to be heterozygous for the amylase mutation assuming all conditions of Hardy-Weinberg equilibrium are met is 1600 flies.

when is the best time to harvest crops?why?

[tex] \huge \bold \blue{★Question★}[/tex]
When is the best time to harvest crops? why?
[tex] \huge \bold \blue{★Answer★}[/tex]
Correct timing of harvest is crucial to crop loss prevention. Grain losses may occur caused by rats, birds, lodging, insects, and shattering. Timely harvesting ensures good grain quality and high market value.
Harvesting too early will result in a higher percentage of unfilled or immature grains, which will lower the yield and cause higher grain breakage during milling. Harvesting too late will lead to excessive losses and increased breakage in rice. Harvest time also affects the germination potential of rice seed.
[tex] \huge \mathsf \orange{MORE \: ABOUT :)}[/tex]
There are different ways to determine the correct harvest time:
Moisture content
Grain moisture content ideally is between 20−25% (wet basis). Grains should be firm but not brittle when squeezed between the teeth.
Ripe grains per panicle
The crop should be cut when 80−85% of the grains are straw (i.e., yellow-colored).
Number of days after sowing
Generally, the ideal harvest time lies between 130 and 136 days after sowing for late, 113 and 125 for medium, and 110 days for early-maturing varieties.
Number of days after heading
For dry season harvesting, an optimum time is 28 to 35 days after heading. In wet season harvest, optimum time is 32 to 38 days after heading.
Other considerations
Harvesting also needs to be timed so that threshing can be done as soon as possible after cutting to avoid rewetting and to reduce grain breakage.
If the crop has a lot of surface moisture, (e.g. from previous rainfall or early in the morning), it is advisable to wait until the surface moisture dries off.

Which is required for both anaerobic respiration and aerobic respiration?
Answers
Answer:
Water, mitochondria, and glucose are all required for both anaerobic respiration and aerobic respiration.
Both anaerobic respiration and aerobic respiration require glucose as a source of energy as glucose is a molecule that is converted into energy in cells and that is used as a fuel source in both aerobic and anaerobic respiration.
What is the significance of the two types of respiration?Aerobic respiration is a type that takes place in the presence of oxygen and forms energy and carbon dioxide and it is the most efficient type of cellular respiration, while on the other hand, anaerobic respiration takes place in the absence of oxygen and results in the production of energy and other metabolic byproducts, such as lactic acid or alcohol.
Hence, both anaerobic respiration and aerobic respiration require glucose as a source of energy as glucose is a molecule that is converted into energy in cells and that is used as a fuel source in both aerobic and anaerobic respiration.
