Explanation:
Answer:
The correct answer is -
In transcription- code the information present in DNA into an mRNA molecule.
In translation- move to the cytoplasm and translate the code into the amino acid sequence with the help of tRNA and rRNA.
Explanation:
Gene expression is the process in which the molecule in which all information present in DNA, first transcribed to RNA and then move to the cytoplasm to translated from RNA to protein with the correct sequence of the amino acid.
RNA plays an important role in gene expression. Each step involves different RNA molecules such as mRNA that is a transcribed RNA molecule that carries information from the nucleus to cytoplasm and binds with another molecule of RNA known as tRNA that translates coded mRNA to the protein.
Thus, the correct answer is -
In transcription- code the information present in DNA into an mRNA molecule.
In translation- move to the cytoplasm and translate the code into the amino acid sequence with help of tRNA and rRNA.
a diploid human cell contain 46 chromosomes if such a cell under go mitosis then how many chromosome will be present in the daughter cells if it has just passed through telophase
Answer:
The daughter cells will have equal number of chromosomes like that of parent cell i.e. 46.
Explanation:
Mitosis is a process of division that creates two new daughter cells with same genetic material and thus equal number of chromosomes. It involves: Prophase, Metaphase, Anaphase, Telophase and at the end cytokine.
In prophase, the nuclear envelope of the cell breaks down along with chromosome condensation. In metaphase, the condensed chromosomes line up at equatorial plate. In anaphase, the sister chromatids of lined chromosomes are pulled towards the opposite poles. While in telophase the cell is ready for division, its nearly dividing stage in which the cell retains its normal structures.

Which best describes the relationship between DNA, genes, and chromosomes?
DNA is the basic unit of life. Long sequences of DNA form genes which contain instructions for producing proteins. Even longer strands of DNA are chromosomes which contain many many genes.
Hope this helps!!
Genes make up DNA and DNA makes up chromosomes this describes best the relationship between DNA, genes, and chromosomes.
What explains the relationship between DNA and chromosomes?In the nucleus of every cell, DNA molecules are packaged in a thread-like structure called a chromosome. Each chromosome is composed of DNA that is tightly wrapped around a protein called histone that supports its structure.
Each gene tells cells how to assemble the components of a particular protein. However, genes (DNA) are located in cell (nucleus) compartments that are different from the cell machines that make proteins (ribosomes).
Chromatin is a mixture of DNA and proteins that make up the chromosomes found in cells of humans and other higher organisms. Many of the proteins, histones, package vast amounts of DNA in the genome into a very compact shape that fits in the nucleus of the cell.

Oxygen is a reactant in cellular respiration. Which term best describes oxygen
in photosynthesis?
Answer:
ANSWER: Oxygen is a product of photosynthesis.
Explanation:
Photosynthesis is a chemical reaction that occurs in plants. Photosynthesis uses ATP energy from sunlight to convert Carbon Dioxide and Water into Glucose. Oxygen is also formed during photosynthesis.
Oxygen is the product of photosynthesis, where water and carbon dioxide are the reactants and G3P and oxygen are the products. This contrasts with cellular respiration, where oxygen is a reactant.
Explanation:When it comes to the role of oxygen in photosynthesis, it is best described as a product rather than a reactant. In the process of photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) and, using the energy from sunlight, convert these reactants into glucose (C6H12O6) and oxygen (O2). The correct statement among the options provided would be option (b), which states that in photosynthesis, chlorophyll, water, and carbon dioxide are reactants, while G3P (glyceraldehyde-3-phosphate) and oxygen are products.
This contradicts the role of oxygen in cellular respiration, where oxygen serves as a critical reactant. In cellular respiration, oxygen is used to break down glucose, producing ATP, water, and carbon dioxide as waste products.

D. methane
Answer:
Starting billions of years ago, algae lowered the
atmosphere.
levels in the carbon dioxide - C.
Algae has been found to have lowered the atmospheric carbon dioxide levels in the environment. Thus, the correct option is C.
What is Algae?In the primitive world, the initially formed organisms such as algae, were found responsible for the production of large amounts of oxygen in the atmosphere. This was possible by the algae present in atmosphere, as they were able to carry out the process of photosynthesis similar to plants, where the food is synthesized in the presence of sunlight, water and carbon dioxide (CO₂), and in return, it generates food and oxygen, on which the organisms are dependent on for their living.
Thus, these algae were responsible for the changes in the atmosphere, by converting carbon dioxide (CO₂) into oxygen and hence lowering the level of carbon dioxide.
Therefore, the correct option is C.

A. Insects must occasionally shed their exoskeleton to grow a new one.
B. The exoskeletons of insects grow along with them throughout their life span.
C. Insects can only grow as large as their hard exoskeletons allow.
D. Adult insects don't have an exoskeleton once they outgrow the one in which they were born.
Answer: A. Insects must occasionally shed their exoskeleton to grow a new one.
Explanation:
In the development process of insects from egg to adult form several intermediate stages occurs. In all immature insects the process of shedding of the skin and the exoskeleton takes place as the insect grows. The exoskeleton of the insect body does not expand as the insect grows it has to get shed and it get replaced with a new and large size exoskeleton. This allows the proper growth of the insect.
Most fossils are deposited in water. How do scientists find them
Answer:
Most fossils are found in sedimentary rocks, those rocks produced by the accumulation of sediment such as sand or mud. Wind and other weathering conditions wash away sediment on land, depositing it in bodies of water. For this reason, fossils of sea creatures are more common than those of land creatures.
Fossils are remain of decayed plants and animals over a very long period of time. Most fossils are found in sedimentary rock deposits which might have been exposed due to erosion, quarrying or at shore.
Fossils are usually found in sedimentary rock deposits, which might have become exposed to the surface after thousands to millions of years after deposition began. Since deposits of rock stretch over a very large area, fossils deposited in water which are preserved in sedimentary deposits may be exposed at shore. Also, fossils such as sea shells mollusk are usually washed up shore in large amount.Therefore, fossils could also be found during quarrying and rock cutting process.

The person's risk of cardiovascular disease would decrease.
The person's bad cholesterol would decrease.
The person’s good cholesterol would increase.
Answer:
The person's risk of cardiovascular disease would increase.
Explanation:
saturated refers to all single bonds in the hydrocarbon chain, meaning no kinks in the chain. The hydrocarbon has the most number of carbons it can have, as there are all single bonds. If the hydrocarbon has even one less carbon, there would be kink, and it would be unsaturated and liquid. Our body needs less carbon, so unsaturated fats are better. But having saturated fats means no liquid, rather solid, which means harder for the blood to get to the heart. So your risk would cardiovascular disease would increase
