Identify the 3 types of natural selection indicates by each graph (please include written descriptions of each!!)

Answers

Answer:

Graph A: Directional Selection

Graph B: Stabilizing Selection

Graph C: Disruptive Selection

Explanation:

Natural selection as a driving force of evolution cam be defined as a process that a population of organisms undergo in other to become adapted to an environment and survive to produce offspring that are fitter.

Thus, the following graphs represents the three types of natural selection:

Graph A: Directional Selection

Directional selection occurs when one extreme trait is favoured over others by selective pressures.

The graph shows that only one extreme trait is favoured as the population that survives seem to have majorly a particular extreme trait.

Graph B: Stabilizing Selection

In this type of natural selection, neither of the extreme traits are favoured by selective pressures. Therefore, intermediate trait become favoured over the other extreme traits.

Graph C: Disruptive Selection

Selective pressures works against the intermediate trait while both extreme trait at the spectrum are well favoured, which become more established in a population against the intermediate trait.

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.

Cytochalasin is a drug that caps actin filament plus ends, thus preventing actin polymerization. Phalloidin is a drug that binds to and stabilizes actin filaments, preventing actin depolymerization. Even though these drugs have opposite effects on actin polymerization, the addition of either of these drugs instantaneously freezes the cell movements that depends on actin filaments. Explain why drugs that have opposite effects on actin filaments can have a similar effect on cell movements.

Answers

Answer:

The correct answer is - these drugs inhibit both the polymerization and depolymerization of actin.

Explanation:

Cytochalasin is a chemical drug that covers or hides the plus end of the actin filament which inhibits the binding of actin monomers and actin polymerization on another hand the Phalloidin chemical makes the actin filaments stable by attaching to them and inhibits the depolymerization process.

The addition of any of these drugs stops the cell movement which is caused by the actin polymerization and depolymerization which is stoped by these drugs. Cell movement is the process that required both actin polymerization and depolymerization.

How does latitude affect a climate zone? (1 point) Group of answer choices Climate zones at low latitudes are hotter because they receive more direct sunlight. Climate zones at high latitudes are cooler because they are closer to the equator. Climate zones at high latitudes receive a lot of precipitation because they are farther from the equator. Climate zones at low latitudes receive little precipitation because they are closer to the ocean.

Answers

The answer is: climate zones at low latitudes are hotter because they receive more direct sunlight.

Climate zones at low latitudes are hotter because they receive more direct sunlight. Therefore, the correct option is option A.

Due to the Earth's tilt and the orbital geometry of its planet, climate zones at low latitudes are hotter because they receive more direct sunlight. The tilt of the Earth's axis in relation to its orbit around the sun is roughly 23.5 degrees. At various points on the Earth's surface during the year, this tilt produces fluctuations in the amount of sunlight that is received. The angle at which sunlight strikes the surface is almost perpendicular in low latitudes, which are nearer the equator. As a result, there is more direct and concentrated heat since the sunshine is concentrated over a smaller area.

Therefore, the correct option is option A.

when is the best time to harvest crops?why?​

Answers

[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.
