How does a worker bee develop a queen out of the larva stage?

Answer:

True

Explanation:

Organic catalyst that increase the rate of biochemical reactions in the cells of living organism s are called enzymes.The are proteins with active sites which are specific to a particular  substrate, for enzyme-substrate complex and later enzyme product complex to formed.

They  act by lowering the activation energy  in the organic chemical reaction therefore increase the rate at which chemical reactions progress.

Hence when  the reactions are too slow,activation energy are high,because enzymes are not available to catalyze the reaction fixing the active sites with the the substrates.

We expect for this cricket species is; The leg mutation might lead to reproductive isolation and speciation due to an effect on the mating call. Option D is correct.

In many cricket species, the sound produced by rubbing the wings or legs together (known as stridulation) plays a crucial role in attracting mates and species recognition. This suggests that changes in the morphology of cricket legs could potentially affect their ability to produce or modulate their mating calls.

If the mutation resulting in thicker hind legs in crickets affects the structure or movement of the legs involved in stridulation, it could potentially alter the characteristics of their mating call. Changes in the mating call can influence mate choice and recognition, which are critical factors in reproductive isolation and the formation of new species.

Hence, D. is the correct option.

Answer:

Multiple alleles of a gene occupy the same locus on the chromosome. Multiple alleles are the alternative forms of the same gene so they influence the same trait. The wild-type allele is mostly dominant over the mutant alleles. The wild type is considered the standard and all other alleles are considered variants.

The statement given "The peritubular capillaries secrete water, glucose, amino acids and ions" is false because the peritubular capillaries do not secrete substances like water, glucose, amino acids, or ions.

Instead, they play a crucial role in reabsorbing these substances from the renal tubules back into the bloodstream. After filtration occurs in the glomerulus, the filtered fluid enters the renal tubules, where various processes, including reabsorption, take place. The peritubular capillaries surround the renal tubules and provide a network for reabsorption. They reabsorb water, glucose, amino acids, and ions from the tubules into the bloodstream, helping to maintain the body's fluid balance and reabsorbing important nutrients and substances. Therefore, the correct answer is False.

Progesterone secreted by the placenta suppresses FSH and LH to prevent the maturation of ovarian follicles.

Progesterone is a hormone secreted by the placenta during pregnancy. Its main function is to help maintain the pregnancy and support the development of the fetus.

One way it does this is by suppressing the secretion of two other hormones, follicle-stimulating hormone (FSH) and luteinizing hormone (LH).

These hormones are responsible for stimulating the maturation of ovarian follicles, which produce eggs for fertilization. By suppressing FSH and LH, progesterone effectively prevents the maturation of additional ovarian follicles and ensures that the woman's body remains focused on supporting the ongoing pregnancy.

This mechanism also helps prevent the occurrence of multiple pregnancies at the same time, which can be risky for both the mother and the fetus.

Adding an air conditioner to the system would contribute to homeostasis by regulating the temperature and maintaining a stable internal environment.

The stimulus in the figure could be the rise in temperature or the detection of a hot environment. The response would be the activation of the air conditioner, which would release cool air into the surroundings. The sensor/control center could be the thermostat or temperature sensor that detects the increase in temperature and triggers the air conditioner to turn on.

Adding an air conditioner to the system would contribute to homeostasis by regulating the temperature within the home. Homeostasis is the body's ability to maintain a stable internal environment despite changes in the external environment. In this case, the air conditioner acts as a mechanism to counteract the rise in temperature and restore balance.

When the air conditioner is turned on, it extracts heat from the indoor air and releases cool air back into the room. This cooling effect helps to lower the temperature and create a more comfortable and stable environment. By maintaining a consistent temperature, the air conditioner helps to prevent overheating, which can have negative effects on the body, such as dehydration, heat exhaustion, or heat stroke.

Furthermore, the air conditioner also helps to control humidity levels in the home. Excessive humidity can lead to discomfort, mold growth, and an increase in allergens. The air conditioner helps to remove excess moisture from the air, contributing to a healthier and more balanced indoor environment.

Eggs hatch under the conditions that are feasible.

Your question is incomplete  but I will tell you something about bhow eggs hatch.

Temperature: The temperature of the environment surrounding the egg is critical for hatching. Eggs must be kept at a specific temperature range that is optimal for the species of egg in question. For example, chicken eggs typically hatch at a temperature between 99-102°F.

Humidity: The humidity of the environment also plays a role in hatching. Eggs must be kept at a specific humidity range that allows the egg to lose or gain moisture as needed to prevent the embryo from drying out or becoming overhydrated.

Incubation time: Most eggs have a specific incubation time, which is the time the egg must be kept at the optimal temperature and humidity before hatching will occur. This time can vary widely depending on the species of animal and the type of egg.

Turning: Eggs must be turned regularly to prevent the developing embryo from sticking to the shell and to ensure that the egg receives equal amounts of heat and oxygen.

Nutrition: Some species of animals, such as birds, will lay eggs that contain a yolk that provides nutrition to the developing embryo. The yolk must be properly nourished and utilized for the egg to hatch.

The marine mammals with front and back flippers are referred to as "pinnipeds," which is a synonym for "fin- or flipper-footed." Animals that live in the ocean but can spend a lot of time on land in this group include seals, sea lions, and walruses.

Pinniped relatives were land-dwelling animals millions of years ago. These were likely creatures that resembled weasels or bears that gradually became more accustomed to life in the ocean as they spent more time there.

Marine mammals in the phocid family can be recognized by their ears and flippers. They are sometimes known as real seals or earless seals. Despite not having external ear flaps, they have ear openings.

On land, they galumph by swaying back and forth on their bellies, using their little front flippers as well. True seals use their rear flippers to push themselves through the water while at sea by moving them back and forth like a fish tail.

When the level of glucose in the environment is low, abundant cyclic   sine mono phosphate (c A M P) binds the   activator protein (CAP) to form the C A P-c A M P complex.

This complex then binds to the DNA. By doing so, it increases the efficiency of RNA polymer  binding at the lac promoter, leading to an increase in transcription of the structural genes.However, when glucose levels are high, the C A P-c A M P complex does not form. Without the complex, RNA polymer   cannot efficiently bind to the promoter, resulting in decreased transcription of the structural genes.

To summarize:
- Low glucose levels lead to the formation of the C A P -c A M P complex, which increases RNA polymer  binding and transcription.
- High glucose levels prevent the formation of the C A P-c A M P complex, resulting in decreased transcription.

Prokaryotes, unlike eukaryotes, have multiple origins of replication which allow for a faster replication process which is false.

Prokaryotes and eukaryotes both have multiple origins of replication, which allows for faster replication. The main difference between prokaryotic and eukaryotic replication is that prokaryotes have circular chromosomes and eukaryotes have linear chromosomes. Because of this, prokaryotic replication occurs bidirectionally around the chromosome from a single origin of replication, whereas eukaryotic replication occurs bidirectionally from multiple origins of replication along the chromosome.

Additionally, prokaryotic replication is generally faster than eukaryotic replication due to the smaller size of the prokaryotic genome and the absence of a nucleus.
