Which of the following describes the most likely location of cholesterol in
an animal cell?
*
Embedded in the plasma membrane
Dissolved in the cytosol
Suspended in the stroma of the chloroplast
Bound to free ribosomes
Based on the diagram, what is the site of modification and packaging of
proteins and lipids prior to export from the cell?
Answer:
1. Embedded in the plasma membrane
2. There is no diagram attached but the question can be answered based on general knowledge. The answer is Golgi apparatus/body.
Explanation:
1. Cholesterol is fat molecule produced in the Smooth Endoplasmic reticulum of animal cells. It is then transported to the plasma membrane, where it plays a vital role in the functionality of the plasma membrane. Hence, embedded in the plasma membrane of an animal cell is CHOLESTEROL, in addition to phospholipids.
2. The Golgi apparatus is an organelle in eukaryotic cells that functions in the modification and packaging of protein and lipid molecules produced by the RER and SER respectively.
The most likely location of cholesterol in an animal cell is A. Embedded in the plasma membrane.
Based on the diagram, the site of modification and packaging of proteins and lipids prior to export from the cell is the Golgi apparatus.
Cholesterol simply means a fat molecule that is formed in the smooth endoplasmic reticulum of animal cells.
It should be noted that the cholesterol is then sent It is then to the plasma membrane,
The Golgi apparatus is an organelle that can be found in eukaryotic cells. The function of the Golgi apparatus is the modification and the packaging of the lipid molecules and the protein molecules that are produced.

Why do you think Flourine is able to pull the electron away from Lithium?
Answer:
Because of its high electronegativity.
Explanation:
Fluorine has ability to pull the electron from the lithium because of its high electronegativity.
We know that as we move from left to right in periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and electronegativity increases. AS lithium is present on left side of period 2 and fluorine is present on right side of same period. Fluorine is more electronegative while lithium is more electropositive thus fluorine pull the electron from lithium when they combine and form anion while lithium loses its valence electrons and form cation.

In cell membranes with aquaporins can water move across the membrane?
1. No, water is polar can not pass the phospholipids
2. Yes, water is able to pass across the membrane through the aquaporins.
3. No, water is too large to pass through the aquaporins.
4. Yes, water is non-polar and can cross the phospholipid bilayer.
Answer:
The cell membranes of a variety of different bacteria, fungi, animal and plant cells contain aquaporins through which water can flow more rapidly into and out of the cell than by diffusing through the phospholipid bilayer.

Answer:
Greenhouse gases
Explanation:
Teddy is working for a nonprofit organization that urges people to stop using products with CFCs. Through this Initiative, Teddy's organization hopes to reduce the concentration of greenhouse gases in the atmosphere.
Greenhouse gases deplete the ozone layer thereby causing global warming as a result often increase in the intensity of Sun rays reaching the earth.
Example of greenhouse gases include chlorofluorocarbon, nitrogen, water vapor etc
Becky is experiencing chronic pain from a medical condition that cannot be treated. In order to minimize the long-term emotional response to her pain, she would choose a modification of her a. Parietal cortex. b. Prefrontal cortex. c. Primary somatosensory cortex. d. Dorsal lateral thalamus. e. Posterior cingulate cortex
Answer:
b. Prefrontal cortex.
Explanation:
The prefrontal cortex is the cerebral cortex that covers the frontal lobe in the brain. The prefrontal cortex plays important roles in pain processing, as well as in pain modulation. In addition, this brain area is connected to other brain regions including the hippocampus, thalamus, amygdala, and further areas of the cerebral neocortex. It has been shown that changes in gene expression patterns, glial cells, neurotransmitters and inflammatory processes are triggered in the prefrontal cortex during both acute and chronic pain, and these alterations are able to modify its functioning, structure, and connectivity.

How many water (H2O) molecules could you line up end to end in a nanometer?
Answer:Molecules have size and different molecules are different sizes. When talking about the size of a molecule, most scientists will mention its molecular weight. That is the total weight of all of the atoms in the molecule. So water, which is made up of two hydrogen atoms (1 atomic mass unit each) and one oxygen atom (16 atomic mass units) has a molecular weight of 18 (well, 18.01528 to be exact). Glucose has a molecular weight of 180. DNA, which is very long, can have a molecular weight that is around 1010 (about the weight of one human chromosome).

Which principle states that two species in the same habitat cannot have the same niche?
niche exclusion principle
competitive exclusion principle
habitat exclusion principle
population exclusion principle
Answer:
competitive
Explanation:
example 1: two male bucks cannot inhabit the same habitat or area because one needs all the females or pride for itself so it chases away the others
The competitive exclusion principle explains that two species occupying the same niche cannot coexist in the long term since competition is created between them for resources.
What is the competitive exclusion principle?It is a phenomenon that refers to the competition that one species has with another and the dependence of one organism to develop in terms of the other organism.
In competitive exclusion, one species is displaced by another when their niches overlap and compete for the same resources.
Therefore, we can conclude that the competitive exclusion principle establishes that two species that have the same ecological needs cannot live together since they create competition between them for resources.

state 4 ways by which through which a soil is depleted
Answer:
Explanation:
Leaching – Plant nutrients are lost beyond the reach of plant roots. Usually caused by excessive rainfall washing nutrients deep down into sub-soil beyond new roots reach.
Soil erosion – Top soil is lost by the agent of erosion e.g. wind, water.
Monocropping – This utilizes only specific nutrients from a particular zone making it exhausted. -It also causes accumulation of certain pests and diseases.
Continuous cropping –This continuously exhaust the fertility of land unless the the land if fallowed.
Change of soil PH -Use of either acidic or basic fertilizers affect soil pH and Consequently the presence of micro-organisms hence soil fertility affected.
Burning of vegetations –Destroys organic matter and soil structure. Nutrients are lost and soil exposed to erosion.
Accumulation of salts – Common in waterlogged areas and semi-arid areas in which poor drainage causes evaporation during the dry periods, making the soil saline.
