A boxer has been jumping rope for an hour. His leg muscles are burning and
he feels weak. Which substance is the most likely
cause of the burning he
feels in his muscles?

Answers

Answer 1

Answer:

anaerobic respiration takes place when you demand your muscles to do vigorous work. normally, aerobic respiration takes place but when energy is needed immediately, anaerobic respiration takes place. during anaerobic respiration,the body produces lactic acid, which leads to the burning sensation. your lungs deliver oxygen to the muscles much slower than the rate you need, since you're putting your muscles through an extensive exercise, and this leads to muscle fatigue.

Describe how the lizard population is changing

Answers

Answer:

Each time lizards colonized an island, they evolved into many of the same forms. .Other lizards adapted to life among the thin branches lower down on the trees, evolving short legs that help them hug their narrow perches. Still other lizards adapted to living in grass and shrubs, evolving long tails and slender trunks.Lizards are low on the food chain. Providing protection from their natural predators ensures their continued existence. Plant bushy perennials, create a rock or brush pile or use man-made items like stacks of bricks or pipes.

chromosomes?

Chromosomes form into genes during cellular reproduction

Genes are special sequences of nucleic acids found on chromosomes

Every gene an organism has is found on every one of its chromosomes

All of an organism's chromosomes can be found next to its genes in the cell nucleus

Answers

Answer:

Genes are special sequences of nucleic acids found on chromosomes.

Explanation:

A single DNA molecule is a chromosome. A gene is a certain chromosome region of DNA.

All cells of the body are genetically the same, but cells are different from others because specific gene sets are expressed. Different cells, therefore express different genes, which enable them to perform a specific function.

The deoxyribonucleic (DNA) genes are segments that contain a code for a certain protein that works in one or several cell types in the body. Chromosomes are cellular structures that contain the genes of a person. Genes that are in the cellular nucleus are contained in chromosomes.

Identify the statement that describes the imperfection of natural selection. Identify the statement that describes the imperfection of natural selection. Natural selection has not had sufficient time to create the optimal design in each case but will do so given enough time. Natural selection is generally limited to modifying structures that were present in previous generations and in previous species. In many cases, phenotype is not merely determined by genotype but by the environment as well. Though we may not consider the fit between the current skeletal arrangements and their functions excellent, we should not doubt that natural selection ultimately produces the best design.

Answers

Answer:

Variability was seen as imperfection, so natural selection could only eliminate the inferior and imperfect, not giving rise to new things, new species.

:

Mendel crossed yellow-seeded and green-seeded pea plants and then allowed the offspring to self-pollinate to produce an F2 generation. The results were as follows: 6,022 yellow and 2,001 green (8,023 total). Which of the following statements correctly describes the relationship of the allele for green soods to the allele for yellow seeds? A. The green allele is dominant to the yellow allele B. The two alleles exhibit incomplete dominance C. The green alicle is recessive to the yellow allele D. The two alleles are codominant

Answers

Answer:

C. The green allele is recessive to the yellow allele

Explanation:

Complete dominance occurs when one gene variant or allele referred to as the 'dominant allele' completely masks the expression of another allele referred to as the 'recessive allele' in heterozygous individuals, i.e., in individuals carrying one copy of the dominant allele and one copy of the recessive allele for a particular locus/gene (whereas homo-zygous individuals carry the same alleles for a given locus/gene). Mendel crossed pure lines of pea plants, i.e., homo-zygous lines for different traits such as seed color (yellow and green) and seed shape (round and wrinkled). In this case, the parental cross was YY x yy, where the 'Y' allele is dominant and encodes for yellow seed color, and the 'y' allele is recessive and encodes for green seed color. From this cross, Mendel obtained a hybrid F1 (i.e., all progeny was heterozygous with genotype Yy). An expected 3:1 ratio as observed in this case (6,022 yellow and 2,001 green seed >> 3:1 ratio) is characteristic of the progeny that results from mating between F1 heterozygous parents, where each parent has one dominant allele and one recessive allele, i.e., F1 parental cross: Yy x Yy >> F2: 1/4 YY (yellow color); 1/2 Yy (yellow color); 1/4 (green color) >> 3:1 ratio of yellow to green seeds.

What are the two main components of the cell cycle

Answers

In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.

In eukaryotic cells or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.

What is  cell cycle?

The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells. These events include the duplication of its DNA (DNA replication) and some of its organelles, and subsequently the partitioning of its cytoplasm and other components into two daughter cells in a process called cell division.

In cells with nuclei (eukaryotes, i.e., animal, plant, fungal, and protist cells), the cell cycle is divided into two main stages: interphase and the mitotic (M) phase (including mitosis and cytokinesis). During interphase, the cell grows, accumulating nutrients needed for mitosis, and replicates its DNA and some of its organelles. During the mitotic phase, the replicated chromosomes, organelles, and cytoplasm separate into two new daughter cells. To ensure the proper replication of cellular components and division, there are control mechanisms known as cell cycle checkpoints after each of the key steps of the cycle that determine if the cell can progress to the next phase.

In cells without nuclei (prokaryotes, i.e., bacteria and archaea), the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells.
