The digestion of starch carbohydrate is initiated in mouth due to the action of starch digesting enzyme ptyalin or salivary amylase present in saliva secreted by salivary glands. Enzymatic hydrolysis helps in the partial breakdown of starch (polysaccharide) into maltose and isomaltose (disaccharides) and small dextrins called 'limit' dextrins. Nearly 30% of the starch is hydrolysed in the oral cavity because of the shorter time the food is retained here

due to the action of starch the carbohydrate digestion occurs first in mouth

Answer:Offspring one- BB

Offspring 3 -Bb

Offspring 4 - Bb

Black % - 100%

White % - 0%

Explanation:

B is dominant over white, And when you draw out the punnett square it all start with a dominant trait.

The possible genotypes for the progeny will be BB, and Bb. and the percentage of black fur will be 100% and for white will be 0%.

The Punnett square is a square diagram often used predict genetic traits of a specific cross or breeding experiment.

It is named after Reginald C. Punnett, who invented it in 1905. Biologists use the diagram to calculate the likelihood of an offspring having a specific genotype.

The Punnett square is a chart that enumerates all of the potential scenarios of a genetic cross between two people with known genotypes.

The Punnett square, in its most basic form, is a square divided into four quadrants.

A Punnett Square is a useful tool for predicting the variations and probabilities that can result from cross breeding. This includes predicting the intercrossing of plants, animals, and even humans.

For the given scenario, the genotype of the offspring will be BB and Bb as per the attached Punnett Square.

Thus, the possibility of the black fur rabbits will be 100% and for white ones it will be 0%.

Answer:

The least genetic variation will probably be found in the offspring of organisms that reproduce using asexual reproduction.

In the descendants of organisms that use mitosis to build a bigger population, the least genetic variety will likely be observed.

Mitosis results in an increased population. Unlike other types of animals that were present at the time, woolly mammoths became extinct thousands of years ago.

Numerous processes can introduce genetic variety, such as mitosis alterations, meiosis crossing over and random orientation, and random fertilization.

All mitotic children share a similar genetic makeup since the duplicate chromosomes' genes are passed down to each succeeding cellular generation.

Each gamete has a unique DNA set because of meiosis's autonomous sorting and recombination. In the resultant zygote, this results in a unique mix of genes.  

Therefore, in organisms that use mitosis to build a bigger population, the least genetic variety will likely be observed.

The clownfish's reproductive strategy of laying eggs near a sea anemone is a form of protection and survival for its offspring.

By laying their eggs in close proximity to the sea anemone, the clownfish provide their eggs with a safe place to develop. The sea anemone's tentacles are a powerful defense mechanism that can fend off potential predators that may try to harm or eat the eggs.

In addition to protection, the clownfish also benefit from the relationship with the sea anemone during the reproductive process. The anemone provides a clean surface on which the eggs can be attached and also helps to oxygenate the surrounding water, which is important for the development of the eggs.

The anemone's tentacles also help to keep the eggs free of harmful parasites and fungi. Overall, the clownfish's reproductive strategy of laying eggs near a sea anemone is a mutually beneficial relationship that helps to ensure the survival of the clownfish offspring.

The protection and benefits provided by the sea anemone help to increase the chances of the eggs hatching successfully, resulting in a higher survival rate for the next generation of clownfish.

A influência da vegetação sobre o clima acontece de diferentes formas, influenciando tanto no albedo quanto na umidade e nas variações de temperatura. Isso significa dizer que alterar a cobertura vegetal de um dado local é também propiciar alterações climáticas no local da intervenção e também em outras partes do planeta. A consequência de uma maior umidade do ar é a menor amplitude térmica (a diferença entre a maior e a menor temperatura), ou seja, a ocorrência de médias de temperaturas mais constantes. Isso ocorre em razão do calor específico da água, responsável por conservar o calor por mais tempo.

Answer:

Itching and other skin problems are signs that a cat or dog may have flea. Fleas are parasites known for their biting and blood-sucking abilities. When they bite, flea saliva enters the pet’s circulatory system, sometimes causing an allergic response commonly seen as a “hot spot” on the pet’s neck or the base of its tail.

Fleas are tiny parasitic insects that infest the fur of dogs and cats. They feed on blood and cause skin irritation that results in itching. If the problem is severe, it can lead to more significant health issues. Pet owners should watch for signs of fleas and treat their pets promptly to avoid complications. Fleas lay eggs on the skin of dogs and cats, which hatch and develop into larvae.

The larvae feed on the skin, shedding as they mature. Adult fleas emerge from the larvae, biting the host to feed on blood. The process repeats itself, with adult fleas continuing to lay eggs on the skin of the pet.The most common sign of fleas in dogs and cats is itching. Pets will often scratch themselves, bite their skin, or lick excessively to relieve the irritation.

Other signs of fleas include red or inflamed skin, hair loss, and the appearance of small, raised bumps on the skin. These bumps are often referred to as "flea dirt" and are the waste products of the fleas. In severe cases, anemia, an allergic reaction, or the transmission of other parasites or diseases can occur.

Flea infestations can be treated with a variety of products, including topical treatments, shampoos, and collars. It is essential to follow the instructions on the product label and treat the pet and the surrounding environment to eliminate the fleas. Prevention is key to avoiding flea infestations, so pet owners should maintain a regular grooming and flea prevention schedule.

The process of reproduction is how organisms create more of their own kind. Contrary to other body systems, the reproductive system is not necessary to maintain an individual's life, even though it is necessary to maintain a species.

Two different types of sex cells, or gametes (GAH-meetz), are involved in the human reproductive process. In the female reproductive system, the male gamete, or sperm, and the female gamete, the egg or ovum, come together. A zygote is the name for the fertilized egg that results from the union of sperm and an egg (ZYE-goat). The zygote undergoes a process in which it transforms into an embryo and then into a fetus.

Ecosystems only have so much food, water, space, and other resources. When different types of organisms all live in these areas, theres only so much that can go around.If an ecosystem has more organisms than its water supply can support then it is beyond its carrying capacity. The ecosystem will not be able to support the organisms and they will have to either relocate or die until the ecosystem is once again at or below carrying capacity.

The carrying capacity of an ecosystem is directly proportional to the limiting factors. Limiting factors increase, carrying capacity of an ecosystem increases.

Carrying capacity may be defined as the maximum number of an individual that can be supported by a habitat. The carrying capacity of any habitat depends on the following two factors:

When limiting factors such as food, space, water, nutrients, etc. in a habitat increase, the carrying capacity of the habitat will definitely increase. This situation remains the same until there will be a scarcity in all those limiting factors suffered by a habitat.

When the limiting factors decline, the carrying capacity of the habitat ultimately lowers.
