Answer:

The correct option is C 32%

According to Chargaff’s rule in a DNA molecule A = T and G = C and A + G + C + T = 100%. Here cytosine (C) is 18% hence G = 18%

∴

A + T = (100 – 36)%

∴

A + T = 64%

∴

A = 32%

Answer:

B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules

Explanation:

DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.

In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.

Answer:

No

Explanation:

No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.

62 \(^oF\) would be 16.67  \(^oC\).

The general formula for converting from  \(^oF\) to \(^oC\) is as follows:

\(^oC\) = (°F − 32) × 5/9

In this case, the °F to be converted is 62. Let's substitute this value into the formula:

62 \(^oF\) = (62 -32) x 5/9

          = 16.67  \(^oC\)

In other words, 62 \(^oF\) is equivalent to 16.67  \(^oC\).

Answer

A is positve and B is negitive

Explanation:

The correct answer is OD. The offspring will show four different combinations of the dominant and recessive traits.

When two individuals are heterozygous for two characteristics, it means that they carry one dominant allele and one recessive allele for each trait. During gamete formation, these alleles can segregate in different ways and combine in various combinations in the offspring.

Using a Punnett square to represent the possible gamete combinations, we can determine that there are four different combinations of dominant and recessive traits that can be observed in the offspring:

Therefore, the correct answer is that the offspring will show four different combinations of the dominant and recessive traits (OD).

In recessive epistasis, the epistatic gene -HERC2- in h0m0zyg0us recessive state inhibits the expression of the hypostatic gene -OCA2-. In the example, the F1 is heter0zyg0us for both genes. Option D. All brown eyes.

When talking about epistasis, we are referring to an interruption.

These are interactions between genes located in different loci in the same chromosome.

An epistatic gene can alter, influence, or suppress the expression of a hypostatic gene.

When the epistatic gene is recessive, the interaction is known as recessive epistasis.

We will assume that

   Genotypes                                    Phenotypes

HHOO, HhOO, HHOo, HhOo          Brown eyes

HHoo, Hhoo                                      Blue eyes

hhOO, hhOo, hhoo                           Blue eyes        

Individuals that are h0m0zyg0us recessive for HERC2 have blue eyes regardless of the genotype of the OCA2 gene.

This is, the genotype hh inhibits the expression of OO, Oo and oo.

Answer:

Explanation:

The algae in the salt marsh are very efficient in their use of the solar radiation they receive.

Solar radiation is the energy emitted by the sun in the form of electromagnetic waves. These waves consist of visible light, infrared radiation, and ultraviolet radiation. Solar radiation is important for life on Earth as it provides the energy for photosynthesis and drives the water cycle.

The amount of solar radiation reaching the ground in a salt marsh in Agusan during the summer is 7,000,000cal/m2/day. This energy is used by the producers (microscopic algae) to photosynthesize and produce organic matter. The gross primary productivity (GPP) of the producers in the salt marsh is 0.0040 g/cm2/day. This means that the algae are able to produce 0.0040 grams of organic matter per square centimetre of salt marsh every day.
The respiration requirement for the algae is 35% of the GPP. This means that in order for the algae to survive, they must use 35% of the GPP for respiration. This leaves 65% of the GPP to be used for growth and other metabolic needs.
Finally, ecologists have found that 1 gram of salt marsh producers (the algae) is equivalent to 2,920 calories. This means that 1 gram of algae in the salt marsh contains enough energy to provide 2,920 calories. This indicates that the algae in the salt marsh are very efficient in their use of the solar radiation they receive.

1. The exocrine function of the reproductive system in females is stimulated by the hormone produced in the anterior pituitary called follicle-stimulating hormone (FSH), which promotes the production of ovarian follicles. The exocrine product in females refers to the release of eggs or oocytes from the ovaries during ovulation.

2. The endocrine function of the reproductive system in females is stimulated by the hormone luteinizing hormone (LH) produced in the anterior pituitary. LH triggers the release of estrogen and progesterone from the ovaries, which regulate the menstrual cycle, promote the development of the uterine lining, and prepare the body for pregnancy.

3. The exocrine function of the reproductive system in males is stimulated by the hormone produced in the anterior pituitary called luteinizing hormone (LH), which stimulates the production of testosterone in the testes. Testosterone is the primary male sex hormone and is responsible for the development of male reproductive organs and secondary sexual characteristics.

4. The endocrine function of the reproductive system in males is stimulated by the hormone follicle-stimulating hormone (FSH) produced in the anterior pituitary. FSH promotes the production of sperm cells (spermatogenesis) in the testes.

Overall, the reproductive system has both endocrine and exocrine functions, with the anterior pituitary gland playing a crucial role in regulating these functions through the production of specific hormones.

Answer:

Nucleotide repeats cause DNA polymerase to “run off” because it finds specific binding sites where the chosen nucleotide cuts will occur.

DNA Polymerase is able to synthesize a new DNA strand from a template strand and aggregate nucleotides at the 3' end of the DNA strand. In fact, it's not just an enzyme that participates in replication, it's a group of enzymes.

With this information, we can conclude that the nucleotide repetitions cause the DNA polymerase to “run off” because it finds specific binding sites where the cuts of the chosen nucleotides will occur.

If species A and species B are in the same family, and species C is in a different family, and if the classification accurately reflects phylogeny, then you can infer that species A and species B are more closely related to each other than either is to species C.

Classification is a way of organizing organisms into groups based on their evolutionary relationships. When two species are in the same family, it indicates that they have a more recent common ancestor than either would with a species in a different family. This is because the classification of similar species into genera and the classification of similar genera into families reflects the phylogeny of the organisms.

Two ground-breaking scientific publications explaining the chemical underpinnings of muscle contraction were published in 1954.

The cylindrical, long cells that make up skeletal muscle. They are referred to as muscle fibers or myofibers because of how they appear. Skeletal muscle fibers are multinucleated cells, which means that they have multiple nuclei (rather than a single nucleus), as a result of the early developmental fusion of numerous precursor muscle cells (embryonic myoblasts).

Some parts of a sarcomere shrink while others remain the same size. A sarcomere is defined as the space between two adjacent Z discs or Z lines; this space is shrunk when a muscle contracts.

Only thick filaments are present in the H zone, which is the center of the A zone, and it shortens during contraction. The I band includes just thin filaments and likewise shortens.
