State the function of centromere
Answer:
The primary function of the centromere is to provide the foundation for assembly of the kinetochore, which is a protein complex essential to proper chromosomal segregation during mitosis. In electron micrographs of mitotic chromosomes, kinetochores appear as platelike structures composed of several layers

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?
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.
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.
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?
[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.

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.
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.
