Hemimetabolous insects do not have a pupal stage in their metamorphosis.

Hemimetabolous metamorphosis is a type of insect development characterized by gradual, incremental changes in form and function as the insect grows and molts. The term "hemimetabolous" means "partial metamorphosis" and refers to the fact that these insects do not undergo a complete metamorphosis with a distinct pupal stage.

Instead, hemimetabolous insects, such as grasshoppers, crickets, and cockroaches, progress directly from the nymphal stage to the adult stage, with no pupal intermediary stage. During the nymphal stage, the insect molts several times, and each molt results in a slightly more mature form. Over time, the nymphal insect will develop the characteristics of an adult insect, including fully formed wings and reproductive organs.

In summary, hemimetabolous insects do not have a pupal stage in their metamorphosis and instead progress directly from the nymphal stage to the adult stage through a series of gradual molts.

In nature, not all individuals in a biological population has the same reproductive success. Additionally, the reproductive succes of an individual may be related to a heritable trait. Disruptive (natural) selection is operating when indivuals with extreme values for an heritable trait have a greater reproductive succes that the ones with intermediate values for the same trait.

Answer:

J stop sending signals to the brain

Explanation:

If a nerve cell stopped functioning, the cell would stop sending signals to the brain. The correct option is J.

Nerve cells, also referred to as neurons, are 'excitatory' cells that can convert a variety of stimulation into electrical signals.

It usually aids in consistent sending information about the external as well as internal environment to the central nervous system in the form of action scenes of action potentials.

Neurons are the basic units of the nervous system, including the cells that receive sensory input from the outside world, send motor commands to our muscles, and transform and relay electrical signals at every phase between each one.

Thus, the correct option is J as any damage in the nerve cell can lead to impaired signaling to the brain.

The yellow cast to the skin that indicates liver disease is referred to as jaundice.

Jaundice is a condition characterized by a yellow discoloration of the skin and whites of the eyes that indicates an elevated level of bilirubin in the bloodstream. Bilirubin is a yellow-colored substance produced during the natural breakdown of red blood cells in the body.

When the liver is damaged, it is unable to process bilirubin effectively, leading to a buildup of bilirubin in the bloodstream, which causes jaundice. The yellowing of the skin is not the only symptom of liver disease.

Other symptoms may include abdominal pain, swelling, and tenderness, nausea, and vomiting, loss of appetite, fatigue, weight loss, and fever. The severity of the symptoms varies depending on the underlying cause of the liver disease and the stage of the condition.

Answer:

Cells are small so that material can cross the cell membrane fast enough. When a cell grows too large it will divide into smaller cells so cell division keeps cells from growing too large.

The key to preventing extinction of any species is adaptation, it allows individuals to survive in their present environment and circumstances and to reproduce, as individuals that aren't adapted enough would die without having the chance to reproduce.

So tha answer is b) Adaptation.

The biological perspective can help us understand the development of phobias and anxiety in several ways. Firstly, natural selection has played a role in the development of these disorders.

Those who are not fearful of certain stimuli, such as dangerous animals or heights, are less likely to survive and reproduce. Therefore, over time, a fear response to these stimuli has been selected for and is now present in many individuals. Genetics also plays a role in the development of phobias and anxiety. Certain genes can make individuals more prone to developing these disorders. For example, research has shown that individuals with a variation in the gene responsible for regulating serotonin are more likely to develop anxiety disorders.
In addition, our ancestors' experiences and fears have been passed down to us through our genes. We may fear threats that our ancestors faced, such as spiders or snakes, even if we have never personally encountered them. This suggests that some phobias may have a genetic basis.
Overall, the biological perspective helps us understand the development of phobias and anxiety by considering both natural selection and genetics. By studying these factors, we can gain a better understanding of why some individuals are more prone to developing these disorders and how we can develop effective treatments.

Tropomyosin is a protein that stabilizes existing actin microfilaments.

Tropomyosin is a two-stranded, alpha-helical coiled-coil protein that twists along the actin filament surface, spanning seven actin monomers. It stabilizes existing actin microfilaments by preventing actin polymerization and depolymerization.Tropomyosin is a long, thin, fibrous protein that binds to the actin molecule's grooves.

It stabilizes actin microfilaments by promoting the formation of microfilaments and inhibiting the depolymerization of microfilaments by sterically blocking actin filament association. Tropomyosin's coiled coil binds to a continuous groove on the surface of actin monomers, which serves as a scaffold for troponin to attach to tropomyosin.The tropomyosin molecule stabilizes the actin filament by preventing the myosin head from binding to the actin monomers, causing muscle contraction.

Scientists have effectively utilized biotechnology to enhance the production of insulin for diabetics. By inserting the human gene of insulin into bacteria.

The correct answer is option D.

Insulin is a hormone produced by the pancreas that regulates glucose levels in the body. Individuals with diabetes either do not produce enough insulin or cannot effectively utilize it. Biotechnology has revolutionized the production of insulin by introducing recombinant DNA technology.

The process involves inserting the human gene responsible for producing insulin into bacteria, such as Escherichia coli. These bacteria act as "factories" for insulin production. The human insulin gene is inserted into the bacterial DNA, allowing the bacteria to synthesize insulin that is identical to human insulin.

The procedure begins by isolating the human gene for insulin and inserting it into a plasmid, a small circular DNA molecule. The plasmid is then transferred into the bacteria, which replicate and express the insulin gene, resulting in the production of insulin molecules. The bacteria can be cultured on a large scale, providing a continuous supply of insulin.

This biotechnological approach has several advantages. First, it allows for the production of large quantities of insulin in a cost-effective manner. Second, the recombinant insulin produced is identical to human insulin, reducing the risk of adverse reactions in diabetic patients. Third, the process can be optimized and controlled, ensuring consistent and reliable insulin production.

This breakthrough in biotechnology has significantly improved the availability and accessibility of insulin for diabetics worldwide. It has reduced dependence on animal sources for insulin production, eliminated shortages, and provided a safer and more efficient means of insulin supply.

In summary, scientists have utilized biotechnology by inserting the human insulin gene into bacteria, enabling them to produce large quantities of identical insulin molecules. This approach has revolutionized insulin production, ensuring a steady supply of insulin for diabetics and improving their overall management of the condition.
