The DNA or deoxyribonucleic acid along with the protein is known as chromatin. In addition to certain proteins, the DNA is packaged.

Further Explanation:

The genetic information is known to be packaged in 23 sets of chromosomes. In these, histones which are the proteins that aid the molecule of DNA to be very tightly packed in added and also aids in maintaining the double-helical structure of the DNA.

Each chromosome comprises of genes. Gene refers to the sequence of the nucleotides which mainly encode for a protein having a specific function. Allele refers to the variant type of the gene. The nucleotides found in the gene can be adenine, guanine, thymine, uracil, and cytosine. These nucleotides make a DNA or an RNA molecule.

DNA undergoes a replication process wherein duplication of the double-helical structure takes place. It then moves further and forms RNA molecule through a process called transcription. RNA undergoes RNA processing followed by post-transcriptional modifications which further release out mRNA, rRNA, and tRNA molecules. All the 3 kinds of RNA enter into the last phase of central dogma called translation. During this, the proteins are formed.

Our genetic information is packed in 23 pairs of chromosomes. In these chromosomes we have histones (proteins that help the DNA to be very compact) and the double helix of the DNA. -

Chromosome- structured like an X; has a centromere in the middle -Nucleotide- thymine, adenine, guanine, cytosine; they are the base pairs that form the double helix of the DNA

Allele- it's a variant form of a gene (for example, in the gene that codes the color of the eyes the alleles possible are: blue, green, brown)

Gene- it's a sequence of nucleotides that code a protein with a certain function.

Genotype- is the genetic characteristics of an individual (the ones that pass of the parents to the children) (the individual has brown eyes but has an allele that "says" brown and the other blue)

Phenotype- the characteristics that we can observe on an individual; traits. (Theindividual has brown eyes)

Why pancreas is called both exocrine and endocrine gland?

PolarNik [594]

Answer:

This question is in my stored notes read below

Explanation:

Pancreas is an exocrine gland as it has a duct to store pancreatic juice secreted by the pancreas and use it whenever required. It is considered as a endocrine gland as it does not have a duct to store the hormones insulin and glucagon which are directly supplied to the blood stream.

If a person is normovolemic and consumes a large quantity of a hyperosmotic solution, it will ________. If a person is normovole

Irina-Kira [14]

Answer:

cause cells to shrink due to an increase in the osmolarity of extracellular fluid.

Explanation:

Normovolemic describes the situation in which a living organism maintains a normal volume or amount of blood in the body.

A hyperosmotic solution can be defined as a solution having an increased level of osmotic pressure. Thus, when there's a greater amount of solute with respect to another solution in a membrane with close similarities, it is known as hyperosmotic solution.

Basically, hyperosmotic solution gives rise to higher difference between solutes and similar solutions.

Hence, when a normovolemic person consumes a large quantity of a hyperosmotic solution, it will cause cells to shrink due to an increase in the osmolarity of extracellular fluid i.e the total number of solute particles with respect to the concentration of a solution (Osm/L).

Which statement best contrasts animals with other living things?

EastWind [94]

<h2>Animals</h2>

Explanation:

A. Animals have muscle tissue, whereas other living things do not.

The character that contrasts animals with other living organism is the presence of muscle tissue. Muscle tissue is exclusively found in animals and are not found in any other kingdom of the living world.

Animals and many other living things posses multiple cells. Most of the cells in organisms are with nucleus.Most of the multicellular organisms have tissue level organization of the body.

Why did Bill Nye pressurize the giant "cloud bottle"? What purpose did this serve?

zubka84 [21]

Answer:

Water molecule is present in air these airborne water molecule are called water vapor, when the molecules are present in air they don't normally stick together as the space is too much.

Bill Nye took a giant bottle and covered it with a stopper and started pressurizing it with a pump to make the molecules come closer and become compressed also it increase the temperature even slightly and that warmth will cause the liquid stick with the smoke particles to go back to forming as vapor.

After that he removed the lid then the air inside the bottle is spread out and it will eventually cool also the kinetically energy is also reduced and that cooled air sticks with dust particle which now forms cloud.

This experiment shows how the clouds are formed and the science associated with it.
