why dolphin and crocodile come up to the water surface for breathing​

Answers

Answer 1

Answer:

Fish use their gills to take oxygen from the water that they live in. But people get the oxygen we need by breathing air, using our lungs. Whales and dolphins use their lungs to breathe air also. That's one reasons why they come to the surface of the ocean.

A cell has chloroplasts, numerous ribosomes, an endoplasmic reticulum, and a cell wall. What type of cell is this?

Answers

Answer:

The cell with chloroplasts, abundant ribosomes, plus an endoplasmic reticulum, and a cell wall is of the plant cell type.

Explanation:

Plant cells are eukaryotic cells found in all plants, with specific characteristics given their ability to be autotrophic and use solar energy to synthesize their nutrients. The presence of many ribosomes and a developed endoplasmic reticulum is due to their high capacity for plant protein synthesis.

One characteristic that differentiates plant and animal cells is the presence of a cell wall, which surrounds the cell membrane, and chloroplasts. Chloroplasts are responsible for making the process of photosynthesis possible.

The descriptive term for plants that are sturcturally adapted to withstand protracted dry conditions is ___________.

Answers

Answer:

Xerophytic

Explanation:

It is xerophytic and it is gotten from Greek word, Xeros( dry) and phutons(plants). It is an adaptive term that is use to describe plants species that posses structural adaptive features which make them to adapt and survive in areas where there is little water or dry region like desert, or area covered with ices by possessing some mechanism which help them to reduce water loss or concerns water. Examples include cactus, pineapple and some Gymnosperm plants. Some of these plants species posses extensive root system and their leaves are reduced to cacti which does not support water loss.

Consider the separate stages of an animal virus life cycle. Assemble a list of structures and processes that are unique to the virus and would make good drug targets for an antiviral agent. Explain your rationale for each choice.

Answers

Answer:

Explanation:

In order to make an antiviral agent, we need to find good drug targets, that is, to find structures and processes that are only present in the virus, so there is no harm on human cells when this antiviral agent is being applied.

In the virion of a naked virus, only nucleic acid and  protein are present forming the nucleocapsid. The nucleic acid and proteins of the capsid, specially, are found only in the virus and therefore make good drug targets. For example, we can express antibodies to recognize the proteins of the capsid and guide the immune system to destroy them.

Although virus particles are  metabolically inert, one or more key enzymes are present  within the virion in some viruses, for example, the reverse transcriptase. This enzyme is only found in viruses and if we find a way to inhibit the activity of this reverse transcriptase, like for example finding a competitor substrate, the virus will not be able to synthesize the DNA needed for its replication.

Regarding processes in the virus life cycle, they all have similar steps: first the attachment of the viral particle onto the cell, then the penetration of the virus, then the synthesis of early and intermediate enzymes using the host cell machinery, and finally the assembly of these viral components and lysis of the host cell to release new viral particles.

The attachment of a virion to a host cell is a highly  specific process. Recognition proteins on the virus recognize  specific receptors on the host cell. Substances that compete with the virion for these specific receptors can be used. If there is no attachment, there is no infection.

describe how and where carbondioxide enters the leafe?​

Answers

Answer:Carbon dioxide cannot pass through the protective waxy layer covering the leaf (cuticle), but it can enter the leaf through an opening (the stoma; plural = stomata; Greek for hole) flanked by two guard cells. Likewise, oxygen produced during photosynthesis can only pass out of the leaf through the opened stomata.

Pressure and depth share a linear relationship. For every _____ meters that the depth of seawater increases, the pressure increases by another atmosphere or bar.

A. 10
B. 25
C. 100
D. 1000

Answers

It is A i just took a test that had the same question on it!!!

For every 10 meters that the depth of seawater increases, the pressure increases by another atmosphere or bar. So, the correct option is (A).

What is Pressure?

Pressure is defined as the force that is exerted per unit area of ​​an object perpendicular to the surface on which that force is distributed. Gauge pressure is the pressure relative to the ambient pressure. Several units are used to express pressure.

It can be expressed as:

[tex]P = \frac{F}{A}[/tex]

Where, P = pressure

F = force

A = area

In water, the greater the depth, the greater will be the pressure, so for every 10 m increase in depth, the water pressure increases by about 100 kilopascals (kPa). The SI unit of pressure is pascal (represented as Pa) which is equal to one newton per square metre [tex](N/m^2 ) or (kg m^-^1s^-^2).[/tex]

Thus, for every 10 meters that the depth of seawater increases, the pressure increases by another atmosphere or bar. So, the correct option is (A).

Describe the energy-releasing reaction shown in figure 1

Answers

idkeubeekenebekeenne

The energy-releasing reaction shown is the reaction of phosphorylation of fructose-6-phosphate to fructose-1, 6-bisphosphate.

Phosphorylation simply means the biochemical process that has to do with the addition of phosphate to an organic compound.

In this case, there's a reaction with fructose-6-phosphate to fructose-1, 6-bisphosphate.

Also, the ATP molecules have three high-energy phosphate groups which are vital for the transfer of one of its phosphate groups to fructose-6-phosphate and also provide energy to carry out the reaction.

Answers

Answer:

D. Take many thousands of years to form

Explanation:

James Hutton discovered thin layers of sediments on his flooded farm and he concluded that strata was part of the earth surface in the past and thus takes many thousands of years to form.

This led to the principle of uniformitarianism which states that the geologic processes now are the same with the ones in the past.

Hereditary is Breast cancer and Inheritance is
Getting Breast Cancer basically it runs in the family inheriting.

Your risk is greatly raised if any of these relatives have had breast or ovarian cancer. However, until many of these “secondary” relatives have the disease.

What is role of inheritance in breast cancer?

A woman's risk of breast cancer nearly doubles if she has a first-degree family (mother, sister, or daughter) who has the disease.

Her risk is nearly three times higher if she has two first-degree relatives. A woman's risk of developing breast cancer is considerably higher if her father or sibling had the disease.

Gene changes that are connected to breast cancer are typically acquired.  Only the breast cancer cells experience acquired DNA alterations over time.

Therefore, Hereditary is Breast cancer and Inheritance is Getting Breast Cancer, basically it runs in the family inheriting.
