Answer:

A. To store the genetic instructions needed to specify traits.

A chromosome is made of a strand of DNA that's encoded with genes.

Answer:

is the site where lipids destined for other cellular compartments are manufactured.

Explanation:

This is because smooth endoplasmic recticulum is an organelles found in eukaryotic organisms that lack membrane bound ribosomes and are found in cells that has much lipids like ovaries, testes, oil glands in the skin e.t.c. They are important in the synthesis of lipids is the site where lipids , Phospholipids, steroid hormones.

They also play a major role in detoxification of harmful metabolic by products and metabolic processes of calcium ions within the cell

Answer:

The correct answer is - a reduced expression of alpha, beta, and omega subunits of RNA polymerase.

Explanation:

Sigma subunit of RNA polymerase is the subunit that the holoenzyme, the other part of the enzyme, identifies and attaches with the specific DNA site called promotors that is responsible for coding the alpha, beta, and omega subunits of this enzyme.

As it is given that there is a deletion in the sigma subunit due to mutation that results in decreased the sigma factor's binding affinity to the promoter region. That ultimately leads to less or unable to bind properly to the promoter and the level of gene expression to fall or be reduced.

Taigas, tundras, and tropical rainforests have a lot of sunlight

It has low temperatures throughout the year. Winter is quite severe and summer is cold.

Also called coniferous forest due to the predominance of pine and spruce.

The vegetation is dense and forms strata, depending on the canopy cover of the trees, which gives rise to different microclimates. The vegetation also has epiphytes, lianas and lichens.

With this information, we can conclude that the tundra, taiga and tropical forest have in common the good disposition of sunlight. Correct answer C:a lot of sunlight.

Answer:

Cytosine: 32%

Adenine: 32%

Thymine: 18%

Explanation:

Therefore, the percent of guanine and adenine should add up to 50%, where the percent of cytosine and thymine should also add up to 50%

Answer:

The bonds are covalent and hydrogen.

Explanation:

Carbon is important in biology because without it, life itself would not exist. Carbon is important in everyday life for all living beings in order for them to live, grow, and reproduce. Carbon compounds are also very versatile and they are in many objects we use every day.

Carbon is the central element to all living organisms. It is the basis to all life on earth. By studying carbon and organic compounds, scientists can learn more about life, the human body, and how it works. Organic Molecules Most organic molecules are made up of long rings or chains of carbon atoms with atoms of other elements attached.

The sun takes an integral role in the photosynthesis stage of the Carbon Cycle. Photosynthesis refers to the process by which plants take in carbon dioxide and water (the products of respiration), and convert it to oxygen, powered by the energy of the sun. Photosynthesis occurs in both land plants and ocean dwelling organisms like algae.

Carbon is the central element to all living organisms, it is key to producing electricity, and the sun needs carbon to produce energy. Therefore, option D is correct.

Because it is present in every biomolecule, carbon is regarded as the element of life. Carbon is a component of all vital biomolecules, including lipids, nucleic acids, proteins, and carbohydrates. The presence of four valence electrons in carbon makes it so distinctive.

The majority of the world's electricity comes from fossil fuels, which also make up the vast majority of the world's transportation fuels like gasoline and diesel. Energy is extracted from fossil fuels through the combustion of hydrocarbons.

Carbon, nitrogen, and oxygen processes convert hydrogen into helium but do not exhaust themselves, providing around 1% of the sun's energy. Hence, option D is correct.

Answer:

Fats and proteins that are present in liver, kidneys, and muscles.

Explanation:

When the reserve of glucose is used by the body during starvation, our body uses fats and proteins that are present in liver, kidneys, muscles etc and convert these fats and proteins into glucose. There is high amount of fats and proteins present in our body which can be used when the glucose reserves depleted from the body during starvation so we can conclude that the fats and proteins are the sources that can be used to produce glucose for the body.

Explanation:

The cell cycle is the most important process in the growth of an organism.

Explanation:

Cell cycle is the fundamental process by which a cell matures, synthesises DNA and divides to form daughter cells. Somatic cells divide regularly.

All multicellular organisms use cell division for growth, maintenance and repair of cells and tissues. Unicellular organisms use this process to reproduce.

Cell cycle affects our daily lives. Most cancers are a result of inappropriate cell division arising due to aberrations in normal cell cycle regulation. Stem cell biology and regulation in growth of organs also involves extensive study of cell cycle.

Chromosomes have hereditary function that are capable of self-duplication and they have thread-like structures seen inside the nucleus of plant and animal. In plants, they go through a cycle called alteration of generation that has multicellular stages. One is sporophyte that is a diploid, and the other is gametophyte with a haploid.

Moreover, spores are produce through meiosis so it go through a process of chromosome reduction in order to create a haploid spores. While, gametes undergo mitosis and the structure is already a haploid, which means that the number of chromosomes will not change in order to produce haploid. In this case, the plant have both spores and gametes and the similarities is that, they are both singles celled and a haploid. Therefore, the number of the chromosome in the gametophyte generation is also 32.
