Answer:
nucleotide, histone, nucleosome, tight helical fiber, supercoil, chromosome.
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
The complex structures of deoxyribonucleic acid (DNA) and protein found in the cell nucleus are generally referred to as chromosomes.
Chromosomes are found in the cell nucleus and are comprised of deoxyribonucleic acid (DNA), histone proteins, etc. Thus, they are used to store genetic informations in living organisms.
The human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
In Genetics, the correct order of structures in a chromosome from smallest to largest are; nucleotide, histone, nucleosome, tight helical fiber, supercoil, chromosome.

what is cell differentiation?
Answer:
The process through which a cell transforms from one cell type to another is known as cellular differentiation. In most cases, the cell transforms into a more specialized form. As a multicellular organism develops from a basic zygote to a complex system of tissues and cell types, it undergoes many stages of differentiation.

How are protons and neutrons conserved as a star ages?
Answer:
Students identify that atoms are not conserved in nuclear fusion, but the total number of protons plus neutrons is conserved. ... Helium and a small amount of other light nuclei (i.e., up to lithium) were formed from high-energy collisions starting from protons and neutrons in the early universe before any stars existed.
6. If the time period were extended to 6 hours, what would be the expected blood sugar level for
Person B?
According to the graph, the blood sugar level for person B is 130 mg/dL after 6 hours of eating meal.
The blood sugar level is highest just after eating the meal but with the passage of time, the concentration of blood sugar level decreases due to absorption by the body. One hour after eating the meal, the blood glucose level is slightly decreases but after 6 hours, the blood glucose level tends to very low due to more consumption of the body or storing by the body in different parts.

Which correctly describes Earth's population over the centuries?
O A. It has risen steadily.
B. It has remained steady overall.
C. It has risen at an increasing rate.
O D. It has declined in some places due to migration.
SUBM
Earth's population over the centuries has risen at an increasing rate. So, the correct option is C.
How the population of Earth is increasing?This sharp increase in population has been primarily caused by an increase in the proportion of individuals reaching breeding age, the gradual extension of human life expectancy, growing urbanization, and quickening migration. This expansion has been accompanied by significant changes in the fertility rate.
One of the key reasons for India's population expansion is a drop in death rates brought on by better medical services and a steady birth rate. The widespread illiteracy in India makes people believe that "children are god's blessings," which makes them opposed to the idea of "family planning." Earth's population over the centuries has risen at an increasing rate.
Therefore, the correct option is C.

2.1explain the body's hormonal response to dehydration
Answer:
Vasopressin, a hormon is secreted by pituitary gland which is response to dehydration , causes kidney to excrete less water.
The body's hormonal response to the dehydration is the action of vasopressin in the kidney. The vasopressin decrease the work of the kidney and it leads to decrease the amount of water secreted by the kidney to save water in the body.
What is dehydration?Dehydration is a condition where there is less water present in the body. There are many reasons of dehydration, like drinking less water or diarrhea. All reactions of the body work by water. So loss of water severely affect the body.
The hormonal response to dehydration is the release of vasopressin by the pituitary gland of the body. The vasopressin saves water from the body to help body fighting with dehydration. It makes the kidney to filter less water.
Thus, the activation of vasopressin in the kidney causes the body's hormonal reaction to dehydration. Vasopressin lessens the kidney's workload, which causes a reduction in the amount of water the kidney secretes to conserve the body's water supply.

Which scenario represents a "fit" individual in terms of evolution?
1 point
The individual can run for long time without getting tired.
The individual has many children that survive and reproduce.
The individual has no children and lives a long time.
The individual has one child that does not reproduce.
Summary
The life history of a species is the pattern of survival and reproduction events typical for a member of the species (essentially, its lifecycle).
Life history patterns evolve by natural selection, and they represent an "optimization" of tradeoffs between growth, survival, and reproduction.
One tradeoff is between number of offspring produced and the amount of energy (both physical resources and parental care) put into each offspring.

Explanation:
Elodea is a plant that lives in water. Like all plants, elodea can make its own food through
process called photosynthesis. Oxygen gas is also produced during photosynthesis.
Photosynthesis can only happen in the presence of light. To measure the rate of
photosynthesis, a piece of elodea can be placed in an inverted test tube filled with a
sodium bicarbonate solution. Oxygen gas produced by photosynthesis will collect at the
top of the test tube.
A student has designed an experiment using elodea plants. The experimental setup is
shown in Figure 1-4
Which of the setups would serve as the control of the experiment?
Bucket
Lamp
Flashlight High
Natural
Elodea
Sodium
bicarbonate
solution
The controlled variable is kept constant during the whole experiment in all the different study groups. In this experiment, Sodium bicarbonate solution is the controlled variable.
------------------------
During an experiment, the controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
In this experiment,
The independent variable → presence/absence of light reaching the plant. The researcher regulates the amount of light by using different elements such as the bucket, lamp, flashlight, and natural light. The dependent variable → oxygen production through which the researcher measures the photosynthesis rate. The controlled variable → Sodium bicarbonate solution. It provides carbon dioxyde, and must be constant in the four scenarios to avoid an effect on the results.-----------------------

what is the drug delivery system for alka seltzer
Answer:
aspirin/citric acid/sodium bicarbonate (OTC)
Explanation:
For the numbered steps below, select the option that places them in the correct order. 1) The ribosome binds to the mRNA and uses tRNAs to translate mRNA into the corresponding amino acid polypeptide sequence. 2) The spliceosome removes introns. 3) The primary structure of the polypeptide chain undergoes hierarchical foldings to form the tertiary structure. 4) RNA polymerase binds to the promoter region of a gene and initiates transcription.
Answer:
first 4, then 2, then 1, and lastly 3
Explanation:
First, RNA polymerase binds to the promoter region of a gene on the DNA and initiates transcription. Transcription is the process by which we get mRNA (coding RNA) which is used as a template for protein synthesis. Then, in transcription, the resulting mRNA undergoes modification and maturation. This involves removal of introns, addition of 3'-poly-A tail and 5'-cap. Introns are sequences that do not code for protein and are hence removed. The structure that removes introns is the spliceosome. Thirdly, mature mRNA travels to the cytoplasm. Ribosome (composed of rRNA) binds to mRNA and tRNA to start the process of protein synthesis. The process of formation of protein is called translation. Lastly, the primary structure of protein may undergo folding to form a tertiary structure.
