Answer:

to shield from predators

Explanation:

A certain mutation causes crickets to stop singing; and not for no reason, it happened as a result of parasitic flys that used the song to find hosts-- and although it worked and fewer crickets died from the parasite it also meant that certain crickets couldn't attract females. This evolved as a way to prevent the parasites from finding crickets and killing them but unfortunately also prevents females from finding them. I hope this helps!

Modern travel along with migration reduces the probability of genetic drift having an effect on the evolution of humans.

In the field of biology, genetic drift can be described as a process by which an existing common gene variant becomes suppressed or caned in a population due to another, better gene variant being introduced into a population.

However, as a result of modern traveling, a population already will have mixed gene variants. This is because of the frequent migrations and travels that a population is not confined to just one gene variant. Hence, this excessive modern travel reduces the probability of genetic drift among humans.

Answer:

All human beings are 99.9 percent identical in their genetic makeup. Differences in the remaining 0.1 percent hold important clues about the causes of diseases.

Explanation:

Our bodies have 3 billion genetic building blocks, or base pairs, that make us who we are. And of those 3 billion base pairs, only a tiny amount are unique to us, making us about 99.9% genetically similar to the next human.

Our bodies have 3 billion genetic building blocks, or base pairs, that make us who we are. And of those 3 billion base pairs, only a tiny amount is unique to us, making us about 99.9% genetically similar to the next human.

What is genetics?

The study of genes and heredity. Heredity is passing genetic information and traits (such as eye color and an increased chance of getting a particular disease) from parents to offspring.

What is the role of genetics?

Genetic research studies how individual genes or groups of genes are involved in health and disease.

Thus, out of 3 billion base pairs, only a tiny amount is unique to us. So humans are genetically similar.

When a link is broken or established, the carbohydrate is more likely to be a suitable source of energy for an organism.

Carbohydrates, often known as sugar molecules, are sugar molecules. Carbohydrates are one of the three fundamental nutrients found in foods and beverages, along with proteins and lipids. Your body converts carbohydrates into glucose. Glucose, often known as blood sugar, is the main source of energy for your body's cells, tissues, and organs. A carbohydrate is a naturally occurring substance or a derivative of a naturally occurring compound with the chemical formula Cx(H2O)y, which is made up of carbon (C), hydrogen (H), and oxygen (O) molecules.

Oxidation and reduction are coupled reactions in which electrons are transferred form one atom to another atom. Reduced compounds donate oxygen or accept hydrogen and oxidized compounds accepts oxygen or donates hydrogen.

So, when the electron carriers are in reduced condition, they accept hydrogens from different metabolic pathways, like glycolysis and TCA cycle, etc. In oxidized state they enter into ETC and donate protons for ATP synthesis. For example, 1 NADH gives 2.5 ATP and 1 FADH2 gives 1.5 ATP.

The most advantageous body plan for an aquatic predatory animal is a fast swimmer and chases prey through the ocean will be (A) radial.

Predatory animals are those that attack and feed upon the smaller and weaker organisms. The animals attacking is called the predator and the animal being attacked is called the prey. The example of predatory animals is: lions, sharks, tigers, etc.

Radial body plan is where the whole body of an organism is arranged around a central axis. The advantage of radial body plan is that the predator animals can grab their food from any direction. The animals possessing radial body plan are jellyfish, sea urchin, etc.

The inability of the liver to perform its normal synthetic and metabolic functions as part of normal physiology is referred to as liver failure. Acute and chronic forms are recognized (cirrhosis). A third type of liver failure known as acute-on-chronic liver failure (ACLF) has recently gained popularity. Chronic liver failure usually occurs in the context of cirrhosis, which can be caused by a variety of factors, including excessive alcohol consumption, hepatitis B or C, autoimmune, hereditary, and metabolic causes (such as iron or copper overload, steatohepatitis or non-alcoholic fatty liver disease).

Cellular energy is mostly produced by the breakdown of carbohydrates, especially glucose. the total oxidative decomposition of glucose into CO2 and water

G°′= -686 kcal/mol is the amount of free energy produced by the process. Glucose is oxidized within cells in a sequence of stages associated with the creation of ATP to capture this free energy in usable form.

Almost all cells go through the process of glycolysis, which is the first step in the breakdown of glucose. Without oxygen, glycolysis takes place and can supply all of the anaerobic organisms' metabolic energy. Glycolysis, however, is only the first step in the degradation of glucose in aerobic cells.

The correct sequence of events for activation of B-cells by T-dependent antigen is recognition of antigen, fragmentation, binding and secretion.

The process can be understood as firstly immunoglobulin receptors on the B cell recognize and bind with the antigen, secondly an antigen fragment in complex with MHC class 2 is displayed on the B cell's surface, thirdly the MHC-antigen complex binds a receptor on a TH cell and finally the TH cell secretes cytokines that activate the B cell. B-cells are the antibody producing cells that produce antigen specific immunoglobin molecule to fight against the pathogens such as bacteria or fungi. These B-cells are found in bone marrow of an individual. Lesser number of B-cells in the body makes it prone to infections as the immune system gets weak. T cells are the types of white blood cells primarily involved in directly killing of infected host cells, activating other immune cells, producing cytokines and regulating the immune response.

One producer might have a lot of parasites; thus, parasite numbers of pyramids are sometimes inverted, with the bottom level being the smallest.

In parasitic food chains, a number pyramid is discovered to be inverted. In these food chains, a single producer typically supports a large number of parasites. More hyper-parasites are supported by the parasites in turn. In this pyramid, the number of people at each level rises from the lowest to the highest.

A graphical representation of the number of creatures at each trophic level is a pyramid of numbers. Given that producers are always more numerous than other trophic levels in an ecosystem, it is a vertical pyramid. There must always be enough plants at the bottom to create food, hence the pyramidal design. If not, the entire food chain would be destroyed.  No predator can be as common as its victim at the upper level.

It is the primary free sugar that circulates in higher animals' blood and can be found in fruits and honey.

Controlling its metabolism is essential since it supplies the energy required for cell activity (see fermentation, gluconeogenesis). Each starch molecule, which serves as plants' primary source of energy, is composed of thousands of linear glucose units.

Another important linear molecule that is primarily composed of glucose is cellulose. Dextrose is the ingredient in D-glucose.
