Plant cells are defined as eukaryotic cells that are autotrophs and are capable of photosynthesizing. All plant cells do not contain chloroplasts as no sunlight reaches that area.
What is chloroplast?Chloroplasts are the organelles of the plant cell constituted of the green-colored pigment called chlorophyll. This pigment is crucial for photosynthetic reactions as they capture the solar energy required to convert the reactants.
The plant parts like underground organs (root system) and inner stems lack chloroplast in their cells as no sunlight reaches that area, hence they are of no use in those systems and organs. They are not exposed to sunlight and cannot photosynthesize.
Therefore, all plant cells do not contain chloroplast as they do not undergo photosynthesis reactions.

In the exhaustion stage of the general adaptation syndrome, the parasympathetic division of the autonomic nervous system may predominate. As a result, __________.
Answer:
many aspects of sympathetic activity are reversed
Explanation:
When he parasympathetic division of the autonomic nervous system predominates, this may result into many aspects of sympathetic activity being reversed. The sympathetic nervous system, which is like the accelerator of the body, is known as the flight or fight nervous system and deals with stress, typically speeding things up. The parasympathetic nervous system, which is like the brakes of the body, helps to conserve energy and protect, typically slowing things down.

describe how tectonic plates contribute to resource distribution
Answer:
When tectonic plates grind along one another they create earthquakes. Areas like this are called transform plate boundaries. As the plates grind along they build up potential energy along the fault, which is occasionally released in the form of vibrations.

Which of the following molecules is an example of a carbon chain that is bent because of the carbon's ability to form double and triple bonds with other carbon atoms?
a.) Saturated fatty acids
b.) Unsaturated fatty acids
c.) Fructose
d.) Glucose
Answer:
B
Explanation:
Unsaturated fatty acids have kinks in the fatty acid chains. Every double bond is a kink.
Unsaturated fatty acids are an example of a carbon chain that is bent because of the carbon's ability to form double and triple bonds with other carbon atoms.
What do you mean by Molecules?Molecules may be defined as one or more groups of atoms held together by various chemical bonds.
On the basis of the number of bonds, fatty acids are classified into two categories, i.e. Saturated and unsaturated fatty acids.
Saturated fatty acids consist of only a single bond with long carbon chains with terminal carboxylic acid, while unsaturated fatty acids consist of double or triple bonds with long carbon chains with a terminal carboxylic acid.
Therefore, unsaturated fatty acids are an example of a carbon chain that is bent because of the carbon's ability to form double and triple bonds with other carbon atoms.

certain cells have densely packed mitochondria and the cristae ( infolded projections of a mitochondrion) are very closely together. what would you predict about the function of such cells? explain your reasoning
Answer:
What can be deduced of cell that have densely packed mitochondria and the cristae are very closely together is that its function requires large amounts of energy.
Explanation:
Mitochondria are cellular organelles in charge of energy production. In these organelles occurs oxidative phosphorylation and electron transport chain, whose final product is ATP, an energy molecule.
A cell with a large number of mitochondria, whose crests are very close together and tight, belongs to a tissue that has a lot of activity and its energy requirement is high.
An example of cells with densely packed mitochondria are skeletal muscle and heart muscle.

Which of the following types of the cell transport moves from low to high concentration and requires energy
Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
Explanation:
This should be correct.

If someone stole your DNA, could they steal your identity?
Yes
Criminals might steal DNA to use the genetic identity of their victim
Answer:
yes and no
Explanation:
if someone actually stole your DNA you wouldn't be alive right now,
but if someone stole "parts" of your DNA you would still be the same person because it doesn't matter what you look like you are your own person an example of this are identical twins, identical twins share the same exact DNA but they aren't the exact same person since they both can like different stuff and have different personalities. but if you mean in a biological stand point "if someone stole your DNA, could they steal your identity" of course not, at least not with our technology.

The theory that explains how this could have happened is called endosymbiotic theory. An endosymbiont is one organism that lives inside of another one. All eukaryotic cells, like your own, are creatures that are made up of the parts of other creatures. Mitochondria, the important energy generators of our cells, evolved from free-living cells.
