The normal human cell contains a single pair of chromosome Option B.

This is because in the human evolutionary lineage two monkey chromosomes fused at the telomere to create the human chromosome 2. As a result, he has one less pair of human chromosomes. A gamete is a haploid cell containing 23 chromosomes, each chromosome being one of a pair of chromosomes present in a diploid cell.

The number of chromosomes in one set is denoted as n, also known as the haploid number. An abnormal chromosome 22 containing part of chromosome 9 and a fusion gene is commonly known as the Philadelphia chromosome. Translocations are acquired throughout life and are present only in abnormal blood cells. This type of genetic change, called a somatic mutation, is not inherited.

When the carbohydrate cellobiose is digested into two glucose monosaccharide sugars (by cellulase in certain fungal species), the resulting glucose monomers are properly defined as the products

The correct answer is option E.

When the carbohydrate cellobiose is digested into two glucose monosaccharide sugars by cellulase in certain fungal species, the resulting glucose monomers are properly defined as the products.

In a chemical reaction, reactants are the starting materials or substances that undergo a change, while products are the resulting substances formed after the reaction. In this case, cellobiose is the substrate, which is the molecule that undergoes the enzymatic reaction. Cellulase is the enzyme responsible for catalyzing the digestion of cellobiose into glucose monomers.

The enzyme cellulase acts as a catalyst in the reaction, facilitating the breakdown of cellobiose into glucose. Catalysts are substances that increase the rate of a chemical reaction without being consumed or permanently changed themselves. However, in the context of the given question, the glucose monomers produced are the final result or product of the enzymatic digestion process.

Therefore, in the digestion of cellobiose, the resulting glucose monomers are correctly identified as the products (option E).

Disease Transmission is a density dependent factor that affects population growth ~

The one that is density-dependent factor affecting population growth is disease transmission. The correct option is C.

Disease, competition, and predation are examples of factors that depend on density. Population size can be correlated positively or negatively with density-dependent characteristics.

These growth-restricting elements have a positive association with population size, increasing as the population grows.

The effects of density-dependent variables change with population size. The effects on various species populations within the same habitat will vary.

Food accessibility, predator density, and disease risk are a few of the variables. The size of a species' population has no effect on factors that depend on density.

Disease transmission is the factor that population expansion depends on density for.

Thus, the correct option is C.

Answer:

$130,410

Explanation:

According to this question, a small family farm has 230 acres of farmland to grow corn. Each acre yields 63 bushels of corn i.e 1 acre = 63 bushels of corn

Also, each bushel can be sold at $9.00 i.e. 1 bushel = $9.00

If 1 bushel = $9.00

63 bushels = 63 × 9 = $567

Since 63 bushels of corn = 1 acre, it means that $567 is made on one acre.

Hence, on 230 acres, 230 × 567 = $130,410 will be made on corn per year

Both dichotomous keys and genetics (DNA) can be used as tools to classify organisms, but the accuracy of classification depends on the context in which they are used.

Dichotomous keys are useful for identifying and classifying organisms based on observable physical characteristics, such as their shape, color, size, and other morphological features. These keys work by providing a series of paired statements that help the user narrow down the possible identification of an organism until a final identification is reached. Dichotomous keys are particularly useful for identifying and classifying organisms that are difficult to differentiate based on external characteristics.

On the other hand, genetics (DNA) is a more accurate way to classify organisms at the molecular level. DNA analysis allows scientists to compare the genetic information of different organisms and identify similarities and differences in their DNA sequences. By comparing the DNA sequences of different organisms, scientists can determine their evolutionary relationships and classify them into different groups. DNA analysis is particularly useful for identifying and classifying organisms that are difficult to differentiate based on external characteristics or for organisms that have evolved to look similar to each other.

In summary, both dichotomous keys and genetics (DNA) are useful tools for classifying organisms, but DNA analysis is generally considered to be a more accurate way to classify organisms as it provides a more detailed and precise understanding of their evolutionary relationships.

The monkey grip procedure involves squeezing an object with one hand while the other arm is passively stretched that causes an increase in the stretch reflex response in the leg muscles of the same side that is being stretched.

The neurophysiological basis involves the activation of descending pathways from the brain modulating the stretch reflex response. When the grip is initiated, activation of motor areas in the brain increases that send signals down to the spinal cord.

These signals inhibit the interneurons activity that causes stretch reflex response causing a greater response in the leg muscles when they are stretched. The stretch reflex involves the activation of muscle spindles in the spinal chord that inhibit or excite the motor neurons that control the muscle.

The monkey grip procedure increases the excitability of the motor neurons controlling the stretched leg muscles that results in a greater stretch reflex response leading to a more forceful contraction of the leg muscles.

Therefore, the monkey grip procedure involves the complex interactions between descending motor pathways from the brain in the spinal cord that underlie the stretch reflex response.
