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.
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.
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.
The descriptive term for plants that are sturcturally adapted to withstand protracted dry conditions is ___________.
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.
I have a question regarding construction building code ? can you help?
Which is not a unique property of water
Answer:
A
Explanation:
All of the other options are specific to water, but quite a few liquids cool off a lot faster than water.
water cools very rapidly is not a unique property of water. Thus option A is correct.
what are the properties of water molecule ?It has no taste, odor, or transparency, where the nucleus of the oxygen atom attracts electrons strongly than the nuclei of the hydrogen atoms.
In water molecule oxygen is more electro negative and electron-greedy than hydrogen, results in the development of a partial negative charge on the oxygen of the water and a partial positive charge on the hydrogen end.
Water shows strong cohesive property where the attraction of molecules for other molecules of the same kind is referred to as cohesion.
Surface tension is defined as the tendency of the surface to resist rupture when they are subjected to stress due to cohesive forces.

From cells to major organ systems, the architecture of the body and the functions the body can perform are very closely related. Can you identify body cells, tissues, organs, systems that demonstrate this relationship and discuss its significance?
Explanation:
body cells- intake the nutrients and specialized into to carry function.
tissues- have similar structure to function well in body like, connective tissue, muscle
organs- carry different identity of function in body like, heart(to pump blood) kidney( for filter and excrete wastes
Rachal Corporation produces and sells a single product whose selling price is $150.00 per unit and whose variable expense is $57.00 per unit. The company's monthly fixed expense is $381,300.
Required:
a. Assume the company's monthly target profit is $9,300. Determine the unit sales to attain that target profit. Show your work!
b. Assume the company's monthly target profit is $18,600. Determine the dollar sales to attain that target profit. Show your work!
Answer:a) if the company's monthly target profit is $9,300, 4,200 units sales is needed
b) if the company's monthly target profit is $18,600, 4,300 units sales is needed
Explanation:
Using The Contribution Margin Approach:
Contribution Margin = Sales expense - variable expense
=$150.00 - $57.00
=$93
Contribution Margin Ratio= Contribution Margin/ sales expense x 100
=93/150 x 100
= 62%
Assume the company's monthly target profit is $9,300.
A) Sales to attain the target profit = [(Fixed expenses + Target profit) ÷ Contribution Margin ratio]
= ($381,300. + $9,300) ÷ 0.62
$390,600 ÷ 0.62
= $630,000
No. of units to be sold =Sales to attain the target profit/ selling price
$630,000/$150.00
=4,200 units
Assume the company's monthly target profit is $18,600
B) Sales to attain the target profit = [(Fixed expenses + Target profit) ÷ Contribution Margin ratio]
= ($381,300. + $18,600 )÷ 0.62
$399,900 ÷ 0.62
= $645,000
No. of units to be sold =Sales to attain the target profit/ selling price
$645,000/$150.00
=4,300 units
