La presencia de un núcleo organizado en el interior de la célula es característica de: a)celula procarionte b) celula eucarionte c) las bacterias d) los virus

Answers

Answer 1

Answer:

Translation- The presence of an organized nucleus inside the cell is characteristic of: a) prokaryotic cell b) eukaryotic cell c) bacteria d) viruses

Explanation:

Eukaryotic.These organim including man, are characterised with a double membrane nucleus, with all its inclusions. Other organisms lack  a well organized membrane bounded  nucleus. Rather they have orgellells that perform nearly similar functions close to the nucleus lying freely in the cytoplasm.

Nucleus is the control and coordinating  centre of the cell.Genetic materials needed for instructions  on how to produce  other  cells organelles are present in the nucleus.

Bacteria, Prokarotes  contain Nucleoid, which is just an irregularly shape region, lacking nuclear membrane.

Viruses lack Nucleus.

5. The occurrence of large or small beak sizes among seed crackers in the absence of
medium sized beaks is an example of
I
a. directional selection.
b. stabilizing selection.
c disruptive selection.
d. none of the above.

Answers

Answer:

Disruptive selection

Explanation:

Disruptive selection favors both of the extremes ( large and small beaks) Thank me later:)

The occurrence of the large or small beak sizes among the seed crackers is the illustration of disruptive selection.

What is disruptive selection?

It is the kind of natural selection, which is bimodal and favors both the extremes traits within a population. It is a kind of natural selection, which opts against the average individual within a population. This kind of selection would show the phenotypes demonstrating both the extremes, however, exhibit very less individuals in the middle.

A classic example of disruptive selection is the size of the beak of the finches on the Galapagos Islands. As the majority of the seeds found these islands were either small or large, therefore, finches with small and large beaks were favored on those islands.

Thus, the correct answer is option c, that is, disruptive selection.

What condition is required for fermentation to occur? A. When oxygen levels within a cell are too low for aerobic respiration B. When the energy production cycle ends of the Krebs cycle C. When a glucose molecule needs to break down completely D. When 20 molecules of ATP are needed\

Answers

Answer:

A. When oxygen levels within a cell are too low for aerobic respiration

Explanation:

Fermentation is a chemical or metabolic process that occurs in organism, when a carbohydrate such as glucose is metabolized or converted to an alcohol anaerobically (absence of oxygen).

When an organism lacks oxygen within the cell, aerobic respiration would be halted, hence pyruvate produced from glucose further undergoes fermentation anaerobically.

Organisms like lactic acid bacteria and yeast carry out fermentation. The process of fermentation is widely used in food industries, such as in brewing of wine or manufacture of yogurt.

How is water introduceed into rivers and streams

Answers

Answer:

As the water flows down, it may pick up more water from other small streams, springs or or from rain or snow melt. ... Small rivers and streams may join together to become larger rivers. Eventually all this water from rivers and streams will run into the ocean or an inland body of water like a lake.Water can be introduced into rivers and streams through surface runoff, springs, groundwater discharge, melting ice and snow, and precipitation. ... The water at the source of the river has high oxygen content, but the width and depth are typically less than they are in the middle sections. The most simplistic answer is that all the water in a river comes from the sky—and that is certainly true, as streamflow is one part of the water cycle. It is also true that most of the water flowing in rivers comes from precipitation runoff from the surrounding landscape (watershed).

What happens to an organisms energy storage molecules when it reproduces

Answers

The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move. Eventually, most of energy used by organisms is transformed into heat and dissipated

An organism's energy storage molecules decrease when it reproduces.

How does energy decrease?

As a transfer molecule, ATP, between exergonic and endogenic reactions, energy is quickly depleted.

When cells divide during mitosis or meiosis, ATP and NADPH are used to power the processes.

As mitochondria are randomly distributed, their ATP generation continues because ATP is not stored but is constantly used.

The hydrolysis of ATP results in the formation of ADP, inorganic phosphate ion, and the release of free energy.

To carry out life processes, ATP is constantly broken down into ADP, and ADP, like a rechargeable battery, is constantly regenerated into ATP through the reattachment of a third phosphate group.

Thus, we can conclude that energy decreases when organisms reproduce.

G Gene expression for fur color is regulated by latitude.

H The arctic fox has two traits for fur color that are determined at birth.

F The alleles for fur color change as the arctic fox grows older."

Answers

Answer:

the correct answer is "J The gene expression for coat color is temperature regulated"

Explanation:

Animals present for the same physical characteristic different phenotypic expressions of the same genome according to the environment in which they are submitted and their affection on them.

The different temperatures makes the fox present different phenotypic manifestations of the same genome, for that reason it is why it changes color and could even change in thickness or quantity.

The following steps happen first during transcription: the RNA polymerase reaches the beginning of a gene that is the second option (B), as the beginning of a gene is the promoter.

What is the significance of the transcription initiation?

Transcription initiation has many implications, such as the fact that prokaryotic initiation is different from eukaryotic initiation, where the RNA polymerase first binds at the promoter site of the gene, where it starts moving towards the gene, and then after reaching the termination site, the transcription stops. In this process, the final product is mRNA from DNA.

Hence, the following steps happen first during transcription: the RNA polymerase reaches the beginning of a gene that is the second option, as the beginning of a gene is the promoter.
