<>In Prokaryotic cell nucleus is absent and DNA is circular and lies free in the cytoplasm but it is not true nucleus . DNA is naked but not associated with proteins or RNA to form Chromosomes. DNA is found in PPLO bacteria and blue algae. Lastly the Nucleoid is the area where prokaryotic cell DNA is located.
Humans produce the enzyme amylase. This enzyme breaks down starch, a
complex carbohydrate found in many food sources (e.g. potatoes, breads).
Explain why the human digestive system is unable to use amylase to break down
the complex carbohydrate cellulose, which is also found in some foods (such as
celery).
Explanation:
We lack the enzyme cellulase which is the enzyme required to break down cellulose.
Base on the given information, human can produce the enzyme amylase, but cannot produce the appropriate enzymes that is able to breakdown the beta acetal linkages that exist in cellulose.
Enzymes serves as biological protein, and it is needed in the body to carry out specific functions.
Human posses amylase which made it possible to breaks down starch that is contained in many carbohydrate food that we eat.
We can conclude that human doesn't have the enzymes that that act on complex cellulose contain in found like celery.

1. State three ways in which protein are important to plant
(3marks)
Proteins are important in plants in order to synthesize cellular components (e.g., organelles), provide structural support cytoskeleton) and carry to metabolic reactions (enzymes).
Proteins are fundamental biomolecules composed of amino acids linked by peptide bonds.In cells, proteins can play diverse structural and enzymatic roles.For example, structural proteins are required to synthesize ribosomes, which serve to assemble other proteins that form the cytoskeleton of cells. Moreover, enzymes are proteins capable of catalyzing chemical reactions such as photosynthetic reactions.In conclusion, proteins are important in plants in order to synthesize cellular components (e.g., organelles), provide structural support cytoskeleton) and carry to metabolic reactions (enzymes).

Biodiversity true or false?
1) Relationships between different species are very important.
2) An environment with 2 million corn plants is more biodiverse than one with 100 corn plants, 25 butterflies, and several other animals.
3) Biodiversity refers to the variety of life in an ecosystem.
4) High biodiversity helps to ensure resilience and stability. In other words, ecosystems with high biodiversity are usually healthier.
Answer:
All are true besides (2)
Explanation:
diversity is variety of things, not mass of them
9. In order to grow two of the exact same plants, a person would reproduce them asexually because the
a) genetic diversity is greater. b).offspring would be genetically identical. c. recessive traits would emerge d). negative traits are suppressed.
Answer:
b).offspring would be genetically identical.
Explanation:
To grow the exact same plants, a person would reproduce asexually because the offspring would be genetically identical. Hence, the correct answer is option b.
What are the different modes of reproduction?There are two different types of reproduction: sexual reproduction and asexual reproduction. In sexual reproduction, the offspring that are formed are slightly different from the parents. This is due to meiotic cell division. Variations in offspring are seen as a result of gene crossing over.
In asexual reproduction, all the offspring are identical to the parents. It is similar to mitosis. Recombination and crossing over do not occur here.So in order to get the exact same plant, this type of reproduction is done by taking a branch from a tree, etc. Others are incorrect statement options.
Hence, to get the exact same plants, a person should go for asexual reproduction, as they produce genetically identical offspring. Option b is the correct answer.

Answer:
Vascular Plants have special vessels that help the plant carry water and sunlight/food throughout the plant, making it survive in conditions where the place has enough sunlight and water. Non vascular plants however don't rely on these, as they rely on the moist locations in places like South America and Hawaii, and dont rely on roots for water comsuption.

what are the many forms of energy? how is energy either potential of kinetic
Answer:
The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.
You need energy to do any work, which is why the ability to do any work is energy. Read that again. Potential and kinetic energy are two forms of energy that can be converted into each other. Potential energy can be converted to kinetic energy and vice versa.

Describe how each of Newton’s laws may be observable during a car trip.
If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest. Additionally, if a car was moving straight when another car struck it, the direction of the car would shift.
What are newton's three law of motions ?According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction pressures upon one another.
There's a fourth law , it states that every object tends to remain in the state it is in right now. We refer to this propensity as inertia. Every object tends to remain in the state it is in right now.
Therefore, If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest (First law) . Additionally, if a car was moving straight when another car struck it, the direction of the car would shift (Third law).

If CO2 is increasing but ethanol is not increasing, what is occurring?
Answer:
Both the products of yeast fermentation, ethanol and CO2, act as product inhibition. Its not toxic, but CO2 will inhibit further fermentation activity of culture yeast.. Hello there. ... Its not toxic, but acid produced during fermentation, will increase the H+ ions in ur media which will hinder further yeast growth.
When no increase in ethanol concentration, while the increase in carbon dioxide, there will be a decrease in the fermentation rate.
What is the role of carbon dioxide in ethanol fermentation?Ethanol fermentation is the process of conversion of sugars into carbon dioxide and alcohol.
The ethanol and carbon dioxide are the products of the ethanol fermentation reaction. The products act as inhibitors of the reaction.
With the increase in the concentration of carbon dioxide, the inhibitor concentration increases, resulting in the inhibition of the fermentation reaction.

Explain why harmful mutations tend to disappear, while beneficial mutations become
widespread.
Answer:
Harmful mutations don't accumulate over time because they reduce the reproductive success of an organism! These mutations would be dead before they can produce any offspring, so there's a slim chance of their genes being passed on. (So it's basically like survival of the fittest, the ones that survive usually have beneficial mutations because that's what keeps them alive lol) Beneficial mutations play a big role in evolution too!

Which table correctly describes the functions of the cell structures
listed
HELP ME PLEASE
Answer:
The correct answer is - cell membrane - regulates cell contents.
Explanation:
Various cell structures have different cellular functions in the cells. The major function of the chloroplast is to produce sugar with the help of chlorophyll pigment by trapping the sunlight. The mitochondria perform cellular respiration and convert sugar to energy.
The vacuoles are the cell structure that helps in maintaining water balance and also store nutrients and sometimes help in waste disposal, however, it is not its major function. The cell membrane is the cellular structure and barrier that regulate what cell content will move outside the cell and what will enter.

The pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing. The skull also has features that can indicate sex, though slightly less reliably. Males have a square jawline and the line between the outer edge of the jaw and the ear is vertical. Conversely, in females the jaw is much more pointed and the edge of the jaw slopes gently towards the ear.
