Per molecule of glucose, cellular respiration results in the production of 38 atp molecules in total.

As a result, a single molecule of glucose can produce up to 36 molecules of ATP throughout the process of cellular respiration. A series of procedures known as glycolysis converts glucose into two pyruvate molecules, each of which has three carbons, and uses them to produce energy.

Aerobic respiration results in a net ATP gain of 38 from one glucose molecule. The electron transport system's oxidative phosphorylation, the link reaction, the TCA cycle, and ATP produced during glycolysis are all included.

In metaphase of mitosis, the chromosomes have two sister chromatids held together by a centromere.

In metaphase of mitosis, the chromosomes in a cell are lined up at the center of the cell, forming a single line called the metaphase plate.

Each chromosome is composed of two sister chromatids, which are held together by a centromere.

The centromere is responsible for the movement and separation of the sister chromatids during cell division.

On the other hand, in metaphase II of meiosis, the chromosomes in a cell are also lined up at the center of the cell, just like in metaphase of mitosis.

However, the key difference is that in metaphase II, each chromosome consists of a single chromatid instead of two sister chromatids.

This is because in meiosis, homologous chromosomes have already separated during meiosis I, resulting in the formation of haploid cells.

So, in summary:
1. In metaphase of mitosis, the chromosomes have two sister chromatids held together by a centromere.
2. In metaphase II of meiosis, the chromosomes have a single chromatid.

This difference in chromosome structure is crucial for the proper distribution of genetic material during cell division.

Mitosis is responsible for the growth, development, and repair of body cells, while meiosis is involved in the production of gametes (sperm and egg cells) for sexual reproduction.

Senator James Henry was a fervent opponent of abolition and thought black people shouldn't have the same rights as white people. He maintained that in order to preserve social order, there must be a class of individuals who carry out the menial tasks and tedium of existence.

He had the opinion that if African Americans were granted the same rights as white people, they would compete with white people for jobs, which would result in lower salaries and higher unemployment.

In order to prevent white people and African Americans from competing with one other for employment, he claimed that it was crucial to establish a class of people to perform menial labour.

The bones possessed by the common ancestor of tetrapods in forelimbs were the humerus, radius, ulna, carpals, metacarpals, and phalanges.

When we compare anatomy and morphology, we find certain similarities and differences between the organisms that exist today and the organisms that existed several years ago.

Humans, bats, cheetahs, and whales all have the same origin as well as same basic structure of the skeleton but those structures have been modified due to the adaptation to the environment in which they live.

The forelimbs of whales are modified into flippers for swimming while the forelimbs of bats are modified into wings to facilitate their flight.

In the above case, the forelimbs are homologous organs.

Homologous organs are those organs that have a common origin but different functions.

They represent common ancestry.

Thus, the bones possessed by the common ancestor of tetrapods in forelimbs were humerus, radius, ulna, carpals, metacarpals, and phalanges.

Direct bone or skeleton ossification refers to the process of creating bones. Beginning between the fourth and fifth stages of embryonic stages and continuing until about age 25, but even this varies slightly between person to person. Intramembranous and endochondral bone ossification are the two forms.

Each of these procedures begins with a mesenchymal tissue precursor, but they vary based on how that major contributor transforms into bone. Intramembranous ossification, which converts mesoderm tissue directly into bone, generates the flat components of the brain, neck, and most of the cranial bones. Endochondral ossification, which starts with mesenchymal tissue changing into an early variety of cartilage and is finally replaced by bone, is the process by which the axial skeleton and bone are produced.

Migration happens as living beings move in and out of an range in a regular design. The entry makes an increment in populace estimate and the exit causes a diminish. In this way the populace measure increments and diminishes in a normal design.

Explanation:

Migration causes population size to change cyclically over time because the two components of migration vary with time.

There are 2 components of migration:

Hence, when the number of people coming into a population is more than the number of people leaving the population, the population size increases. On the other hand, when the number of people leaving a population exceeds the number of people coming in, the population size decreases.

Muscle contraction-specific cells exist. Walking is made possible by muscles, and they also support physiological functions including digestion and respiration.

Skeletal muscle, cardiac muscle, and smooth muscle are the three different forms of muscle found in the body.

Skeletal muscle tissue develops into skeletal muscles, which connect to bones or skin and regulate movement that can be consciously controlled as well as locomotion. Skeletal muscle is also referred to as voluntary muscle because it may be directed by mind. Skeletal muscles are long and cylindrical in shape, and their tissue appears striped or striated when seen under a microscope.

The consistent arrangement of contractile proteins is what causes the striations (actin and myosin). Actin, a globular contractile protein, works with myosin to contract muscles. Multiple nuclei can be found in a single cell of skeletal muscle as well.

When we say that a mutation is silent or neutral, we mean that the mutation has occurred in a gene, but it does not result in any observable or measurable changes to the organism.

A silent mutation is one that occurs in a non-coding region of DNA or in a gene, but it does not change the amino acid sequence of the protein that is produced from that gene. A neutral mutation is one that does change the amino acid sequence of the protein, but it does not affect the function of the protein. In both cases, the mutation has occurred, but it does not have any impact on the phenotype or characteristics of the organism.
