The populations that were hurt by adding bears were the populations of smaller animals such as rabbits, rodents, and other small mammals.

What do you mean by mammals?

Mammals are a group of vertebrate animals that are characterized by the possession of hair or fur, mammary glands that produce milk to feed their young, and three middle ear bones. They are warm-blooded and give birth to live young rather than laying eggs. Examples of mammals include humans, cats, dogs, horses, and whales.

The mentioned smaller animals are a primary food source for bears, so by increasing the bear population, the populations of these animals would be reduced.

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 dust bowl refers to a period of drought during the civil war.

The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s. The phenomenon was caused by a combination of both natural factors and manmade factors.

Economic depression coupled with extended drought, unusually high temperatures, poor agricultural practices and the resulting wind erosion all contributed to making the Dust Bowl.

The Dust Bowl, also known as “the Dirty Thirties,” started in 1930 and lasted for about a decade, but its long-term economic impacts on the region lingered much longer.

part a.

it would take an estimated 2984 years for the element to undergo complete radioactive decay.

N = N₀ * (1/2)\(^(^t ^/^ T^)\)

N = final number of atoms remaining

N₀ =  initial number of atoms

T =  half-life of the element

0 = 2000 * (1/2)^(t / 430)

(1/2)^(t / 430) = 0

log₂((1/2)= log₂(0)

(t / 430) * log₂(1/2) = log₂(0)

0.01 = (1/2)^(t / 430)

log₂(0.01) = (t / 430) * log₂(1/2)

t = log₂(0.01) * 430 / log₂(1/2)

Label a growing bacterial or cell culture for a brief interval with a mixture of 14C-labeled nucleosides, which would be converted to nucleotides and incorporated into  DNA Isolate total Protein and subject it to hydrolysis with mild temperature. Every  Nerve-terminal nucleotide will be released as a nucleoside. Separate nucleosides from nucleotides, by  Esterification of inorganic phosphate to C5 on aldose.Total picomoles of nucleotide in the hydrolysate divided by total picomoles of nucleoside gives the number of nucleotides incorporated per  nucleic acid polymer chain-which, when divided by the labeling interval (minutes) gives the growth rate of individual chains (nucleotides incorporated per growth rate chain per minute). An interesting variant of the experiment would be to carry it out with individual radiolabeled nucleosides and ask whether the chain  growth rate is the same for each nucleotide.

Nucleosides have nitrogen base surrounded by 5 carbon carbohydrates which is called as ribose molecule. Nucleotides is simply a nucleoside with one or more phosphate group. There are 4 different types of nucleosides which are, adenosine,  guanosine cytidine, and uridine. Nucleotides are formed from nucleosides by esterification of inorganic phosphate on aldose.

Answer:

maybe B. because it occurs because of human water pollution

The negative change to feed levels in aquatic ecosystems caused by human activity is cultural eutrophication. Therefore, the correct statement is option B.

Cultural eutrophication is the process by which human activities, such as agricultural runoff introduce excessive nutrients into aquatic ecosystems. This can lead to an overgrowth of algae and other aquatic plants to deplete oxygen levels in the water as they decompose.

This can negatively impact feeding levels in aquatic ecosystems by reducing the food availability for organisms that live in the water and these negative changes to feed levels in aquatic ecosystems are due to human activity.

Biological oxygen demand is a measure of the amount of dissolved oxygen needed by biological organisms in water to break down organic material, whereas endocrine disruptors are chemicals that interfere with the endocrine system of organisms.

Therefore, cultural eutrophication causes negative changes to feed levels in aquatic ecosystems caused by human activity.

Answer:

Diploid microspore mother cells divide by meiosis to form four haploid microspores. Each microspore develops into a pollen grain by mitosis.

Explanation:

Pollen grains contain the male gametes of a sexually reproducing plant. Pollen grains are haploid cells in nature produced by the meiotic division of microspore mother cells (located in the anther). The meiosis of these diploid (2n) microspore mother cells give rise to four haploid microspores. This process in plants is called microsporogenesis.

Each haploid microspore (n) develops into pollen grain called microgametophye (bearing male gamete) via mitotic division. During the pollen grain formation, a wall is formed around the microspores.
