Answer:

The genetic material of most of the organism is Dexoxy-ribonucleic acid OR DNA which are formed of the monomer unit called nucleotide. Each nucleotide is composed of a 5-C deoxyribose sugar, a phosphate group and 4 types of nitrogenous bases mainly adenine, cytosine, guanine and thymine.

It is the sequence of these nitrogenous bases which determine the fate of a cell as these nitrogenous bases are read by the ribosome in the form of triplets called codons where each codon codes for specific amino acids. These amino acids bind to each other via peptide bonds to form proteins.

Thus, these nitrogenous bases control the important property of the cell.

Arlecino [84]

<h2>Answer is option "C"</h2>

Explanation:

All in all, this procedure includes a "parent" cell parting into at least two "little girl" cells. Right now, parent cell can give its hereditary material from age to age.
Meiosis, then again, is a particular type of cell division that happens in living beings that imitate explicitly. As referenced above, it produces regenerative cells, for example, sperm cells, egg cells, and spores in plants and parasites.
In people, extraordinary cells called germ cells experience meiosis and at last offer ascent to sperm or eggs. Germ cells contain a total arrangement of 46 chromosomes (23 maternal chromosomes and 23 fatherly chromosomes). Before the finish of meiosis, the subsequent regenerative cells, or gametes, each have 23 hereditarily one of a kind chromosomes.
Hence, the right answer is option C "four strings, each a combination of different colors"

What causes an increase in the number and intensity of small earthquakes before an eruption?

DiKsa [7]

Before an eruption, scientists look for gases and changes in the volcanoes shape, before an eruption the number and intensity of small earthquakes increases, this is caused by the movement of magma, prior to the eruption. Magma forms in the mantle and is a result of high temperature and low pressure.

Considering the ATP cycle, which of the following would have the most potential energy to perform work for cell activities? A. A

Mumz [18]

Answer:

ATP

Explanation:

We are well aware of the fact that ATP is considered to be the energy currency of the cell. If we talk about cell activities it needs an energy input. No doubt that H+ ions play an important role in electron transport chain step of the production of ATP, but the ultimate product which is used by the cell is ATP.

AMP and ADP are also energy sources but they contain less amount of energy as compared to ADP because in ATP there are three phosphate bonds and each bond upon breakage releases almost 7.3 kj/mol of energy. So it definitely will be more in ATP as compared to ADP and AMP.

Rufina [12.5K]

Answer:

The scientific study of life, called Biology, can be organized around several themes. As the biological hierachy builds from molecules on up to ecosystems, each level has  emergent properties that result from interactions among component parts. Life's basic unit of structure and function is the cell, which occurs in two basic forms- prokaryotic and eukaryotic . As organisms interact with the environment, nutrients and chemicals cycle within an ecosystem, while energy flows one way from sunlight -> chemical energy -> heat. According to the core theme of evolution all of life is related by common descent. Life was diversified as natural selection had led to the gradual accumulation of adaptations that fit populations to the environment.

Explanation:

Emergent properties- Properties that is exhibited by a group of individuals as a result of interaction among them.

Evolution- the process by which populations develop new characteristic and become more efficient than their ancestors.

Natural selection- A phenomena in which only fittest organisms of a population are allowed to survive in a given environment. This play a key role in evolution.
