What step of respiration does anaerobic (not requiring oxygen)
and aerobic (requiring oxygen) respiration share?

Analogous structures demonstrate that identical selective pressures might result in similar adaptations, whereas homologous structures indicate evidence for shared ancestry. biological molecules' distinctions and similarities.

If two or more species have similar physical characteristics, it's possible that all of them inherited them from a common ancestor. Homologous structures are traits that are similar because they have a common ancestor. A structural homology is the comparable bone arrangement in the forelimbs of humans, birds, and whales.

With a large upper "arm" bone and a smaller lower "leg" bone, the flipper of a whale, the wing of a bat, and the leg of a cat are all strikingly similar to the human arm.

Answer:

1/2 (50%)

Explanation:

During meiosis, homologous pairs of chromosomes are separated in order to form haploid cells, and this separation or assortment is known to be a random process. In consequence, the chromosome carrying the mutation will have a 1/2 (50%) chance of being inherited in the gamete that, after fertilization, produces a non-viable organism. In consequence, the non-mutated chromosome also will have a 1/2 chance of occurring in the offspring

The main difference is that Animal Cells do not have a cell wall, plants do. there's obviously more but I believe that's the main difference

A cell membrane and a cell wall are features of plant cells. The cell membrane is surrounded by the cell wall in plants. The plant cell's distinctive rectangular shape is due to this. Plant cells lack the centrosome and lysosome, while animal cells only have a cell membrane and no cell wall, giving them a circular shape. Unlike animal cells, plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole.

The linking number of a closed-circular, double-stranded DNA molecule is changed by breaking a strand, unwinding or rewinding the DNA, and then rejoining it. Each of these manipulations alters the degree of supercoiling, which in turn affects the Lk of the molecule.

The linking number (Lk) of a closed-circular, double-stranded DNA molecule is a topological property that describes the number of times the two strands of DNA are intertwined around each other. It is important to note that the Lk of a DNA molecule is conserved, meaning that it cannot be changed unless some sort of topological manipulation is performed on the molecule.

Breaking a strand of DNA will alter the Lk of the molecule, as it changes the number of times the strands are intertwined. For example, if one strand of a double-stranded DNA molecule is broken, the two strands will separate, and the linking number will decrease by one. This is because the number of times the strands are intertwined is reduced by one, as the broken strand is no longer intertwined with the intact strand.

Unwinding or rewinding the DNA molecule can also alter its linking number. This is because the Lk of a DNA molecule is directly proportional to its degree of supercoiling. When the DNA molecule is unwound, the number of times the strands are intertwined is reduced, and the Lk decreases accordingly. Conversely, when the DNA molecule is rewound, the number of times the strands are intertwined increases, and the Lk increases accordingly.

If the DNA molecule is broken and then re-joined after unwinding or rewinding, the linking number will be restored to its original value, as long as the strands are rejoined in the correct orientation. This is because the act of rejoining the broken strand will restore the degree of supercoiling to its original value, and the Lk will be conserved.

Explanation:

Compact bones are the strong, outer layer of bones that make up 80% of the bone's weight whereas spongy bones are weak, and make up 20% of bone's weight.

Compact bones, also known as cortical bones, are bones that are denser and harder than spongy bones. Compact bones make up the outer layer or cortex of long bones, such as the femur, and are composed of a matrix of collagen fibers and hydroxyapatite crystals. These bones are strong and provide protection for the internal structures and organs of the body. Compact bones also provide support and movement while protecting us from injury.

Spongy bones, also known as cancellous bones, are bones made up of a network of spaces filled with red bone marrow. Spongy bones are usually found in the ends of long bones and are important in providing blood cells, which support the entire body's functions. Unlike compact bones, spongy bones have a lower mass-to-surface area ratio and therefore absorb shock and vibrations better. Spongy bones are also known for their ability to easily remodel in response to stress, allowing them to adapt to an individual's daily activities.

In pea plants, the yellow seed color is dominant to green, and the letter "Y" is typically used to represent the yellow allele, while "y" represents the green allele. The correct answer is d) 50:50.

In genetics, heterozygous refers to an organism that has two different alleles (versions of a gene) for a particular trait. Each parent contributes one allele to the offspring, so a heterozygous individual has inherited one allele from each parent that differs in their DNA sequence.

If a heterozygous yellow-seeded plant (Yy) is crossed with a green-seeded plant (yy), the possible gametes for the yellow-seeded plant are Y and y, while the green-seeded plant only produces y.

The resulting genotypic ratio of the F1 generation would be 1:1 (Yy: yy), and the phenotypic ratio would be 1:1 (yellow: green). Therefore, the correct answer is D) 50:50.

Peroxisomes are able to import folded proteins by using the peroxisomal targeting signal-1 (PTS1) and peroxisomal targeting signal-2 (PTS2) sequence that is located on the C-terminus and N-terminus of the folded protein, respectively.

These signals allow the folded proteins to be recognized by the receptor proteins and to be imported into the peroxisomes by using a translocation mechanism, known as peroxisomal importomer.However, the peroxisomal membrane is impermeable to NADH and acetyl-CoA due to the presence of two specific proteins that are responsible for transporting NADH and acetyl-CoA. These proteins are called NADH and acetyl-CoA transporters, respectively. These transporters act as a selective gate that allows only NADH and acetyl-CoA to enter the peroxisomal matrix, while preventing other molecules from entering.

This selectivity is due to the specific shape and charge of the transporters that are designed to recognize and transport only NADH and acetyl-CoA. Therefore, the peroxisomes are able to import folded proteins, while maintaining the selective permeability to NADH and acetyl-CoA by using different mechanisms and transporters.
