The Sensory neuron is the structure that first receives an impulse triggered by the stimulus. Thus, the correct option is D.
What are Sensory neurons?Sensory neurons may be characterized as nerve cells that are activated by sensory input or external stimulus from the environment.
When a person touches a hot object and immediately moves her finger away from it. This is because sensory neurons are activated by an external stimulus, which is sent to the central nervous system of the body, and a motor response is sent out to the skeletal muscles that regulate this movement.
Therefore, the correct option for this question is D.

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.

B.
one copy, two copies
C.
two copies, four copies
D.
one copy, four copies
Answer:
B. one copy, two copies
Explanation:
Haploid is 23 chromosomes, so there is one copy of each human chromosome while diploid is 46 chromosomes, so there are two copies of each human chromosome.
Halpoid refers to a cell with a single set of chromosomes
Diploid refers to a cell with two sets of chromosomes.

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.

Why is a sea otter a “keystone”??
Explanation:
Sea otters are an iconic species, representing the beauty and diversity of marine life found along California’s coastline. They’re also considered a keystone species because of their critical importance to the health and stability of the nearshore marine ecosystem. They eat sea urchins and other invertebrates that graze on giant kelp.

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?
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.
