And causes either mechanical or chemical weathering? Brainliest and 13 points to the right answer!

Answer:

D

Explanation:

The correct answer would be Nucleic Acid.

A typical nucleic acid has 3 components which include:

The purine base includes adenine and guanine while the pyrimidine base includes thymine/uracil and cytosine. The 5-carbon sugar could be ribose or deoxyribose depending on if the nucleic acid is ribonucleic or deoxyribonucleic acid.

The only macromolecule that contains the 3 components of the options A to D is the nucleic acid. Hence, the correct option is D.

The changes in wind currents affect the short-term climate in a region occurs prevailing winds can cause heavy rains or a dry climate.

Climate change can be caused by natural processes on the Earth itself or by external forces, including variations in the intensity of sunlight, or even more recently, by human action.

The changes in the sea currents which affect the waters and the climate of the region. Thus the answer is prevailing currents created large rain. These events lead to the creation of the changes that lead to the formation of the weather changes.

Integumentary system helps regulate body temperature and water loss. Thus option B is correct.

In our body integumentary system is present in the outer layer. It’s made up of your skin, nails, hair, and the glands and nerves on your skin. It acts as a physical barrier — protecting your body from bacteria, infection, injury and sunlight. It also helps regulate your body temperature and allows you to feel skin sensations.( like hot and cold.)

Integumentary system present in skin:-

Dermis, epidermis, Hypodermis

Integumentary system present in nails:-

Nail plate, Nail bed, Cuticle, Matrix, Lunula

Integumentary system present in hair:-

Hair shaft, Hair bulb

Functions of integumentary system:-

Hence, integumentary system is more important in body for the regulate temperature and water loss. Thus option B is correct.

Answer:

Explanation:

ATP, adenosine triphosphate, is a molecule high in chemical energy.  It is made up of a ribose ring, the nitrogenous base adenine, and 3 phosphate groups in a phosphoester linkage at carbon 5

ATP is broken down, losing a phosphate group, and energy is released from breaking the phosphate bond. The other two phosphates in ADP are lined by stable p hosphoanhydride bonds.

[tex]ATP+H_{2}O[/tex] → [tex]ADP+Pi+free \hspace{0.1cm} energy[/tex]

In the body, ATP molecules are used to provide energy for detoxification in forms of active transport; fueling biosynthesis- the modification of different compounds to form macromolecules; and muscle contraction, providing energy to myosin, and braking myosin actin cross-linkages to free myosin for other contractions.

The answer is A.) Water has unusually strong hydrogen bonding. These bonds require extra energy to break. Therefore, water has a high specific heat.

Answer:

it steams cuz of the hot mixing with the cold

Answer:

Offspring will usually have half the amount of chromosomes from each parent. For example: Mother Human= 46 Chrom, Father Human= 46 Chrom, Baby Human= 23 Chrom from father and 23 Chrom from mother.

There are just half as many chromosomes. Typically, children inherit half of each parent's chromosomes.

As an illustration, the mother and father of a human have 46 chromosomes each, and the baby has 23 chromosomes from each parent.

The sister chromatids reach their opposing poles at this final stage of mitosis. The cell's tiny nuclear vesicles start to reform around the chromosome cluster at each pole. As the process by which the parent cell transfers its DNA to its two daughter cells, mitosis is a crucial component of cell division.

Homologous chromosomes align in pairs during meiosis. Chromosomes are independent of one another during mitosis.

Therefore,  half as many chromosomes the chromosomes of an offspring cell compare with the chromosomes of the parent cells.

Answer:

In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).

Explanation:

Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.

From the sequence:

AUGGUGCAUGUC

Four codons are obtained, each of which encodes a different amino acid:

Codons:          AUG-GUG-CAU-GUC

Amino acids:  Met - Val - His - Val

Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.

Explanation:

Answer: Rosalind Franklin discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick's suggestion that DNA is a double-helix polymer in 1953.

Explanation:

Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.

She was one of the greatest scientists who made significant contributions to the field of DNA by using X-ray crystallography, and apart from that, she also made contributions to the field of virology. As X-ray diffraction facilitates the study of the structure of viruses such as the tobacco mosaic virus and the polio virus and helps in understanding the replication of viruses, it is also helpful in the study of the structure of coal and other carbon-based materials.

Hence, Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.
