Why do plants not have any special respiratory organs like animals? Give two reasons.
Answers
Answer:
Hmm.
Explanation:
'Plants do not have lungs or any respiratory orgasm in themselves so they don't need the process of respiration. Plants do not need a respiratory system because roots, stems, leaves of plants exchange gases for respiration separately. They don't have lungs to breathe so they don't need a respiratory system.'
Basically, plants don't need respiratory organs because they have roots, stems, and leaves, which they use to breathe.
Also, because they are plants. These are the same guys who take energy from the sun.

4. Jimmy likes to work with his friend Joe in 7th grade science class labs. However, he notices that he tends to get lower grades when he does work with Joe, because he and Joe like to talk about basketball and not science. He's decided to investigate if his science lab grades are higher when he works with Joe or if they're higher when he works with someone else. He has set goals to become a better student, so help him write a hypothesis for his study. a. Manipulated variable b. Responding variable
Answers
Answer:
If Jimmy works better with someone other than Joe, then Joe is a part of the problem of Jimmy getting lower grades.
b responding variable
Explanation:
If, then statements are used for scientific hypothesis's.
In an experiment, there is always a manipulated variable and a responding variable.
In Jimmy's experiment, his aim is to determine whether working with someone other than Joe will lead to an improvement of his grades so he can have a hypothesis that reads thus; "Working with another student other than Joe will lead to improvement of my grades".
In this experiment, the manipulated variable is his study partner while the responding variable is his grades.

The layer of the Earth called the mantle is often described as convecting. In this context, convection is
A.
a process that keeps the mantle stationary.
B.
a continuous cycle in the Earth's interior.
C. a step in the formation of sedimentary rock.
D.
a process that occurs on the Earth's surface.
Answers
Answer:
B
Explanation:
Convection occurs to divert heat generated by the core and spread through the mantle. at the bottom of the mantle, heat is gained, causing the mantle to be less dense and rise up. at the top, heat is subsequently lost, resulting in am increase of mass and a drop down for the mantle. this process repeats indefinitely
Convection is a continuous cycle in the interior of the Earth.
Convection of Earth's mantleThe prime mechanism of heat transfer in the mantle of the Earth is convection.
Convection of mantle illustrates the movement of the mantle as it mediates heat from the white-hot core to the brittle lithosphere.
It is a thermally driven procedure in which heating at depth makes the material to expand and become less dense, making it to elevate while being substituted by the complimentary cool substance, which sinks.
This phenomenon of heat gain and heat loss takes place continuously in the mantle of the Earth.
Thus, the correct answer is option B.

The almost pure cellulose obtained from the seed threads of Gossypium (cotton) is tough, fibrous, and completely insoluble in water. In contrast, glycogen obtained from muscle or liver disperses readily in hot water to make a turbid solution. Despite their markedly different physical properties, both substances are (14)-linked D-glucose polymers of comparable molecular weight. What structural features of these two polysaccharides underlie their different physical properties
Answers
Answer:
Cellulose is held by beta 1,4-glycosidic bonds making it linear while Glycogen is held by an alpha 1,4-glycosidic bond making it highly branched.
Explanation:
Cellulose and Glycogen are both carbohydrate polysaccharides formed from glucose monomers. According to the question, cellulose is a tough, fibrous, and insoluble (in water) polymer found to play a structural role in plants' cell wall while Glycogen is another polymer obtained from muscle or liver and disperses readily in hot water to make a turbid solution.
Although these two polysaccharides (cellulose and glycogen) are linked by (1, 4)-glycosidic bonds but the glucose monomers in CELLULOSE are linked by a beta 1,4-glycosidic, hence, making it a straight or linear polymer
GLYCOGEN, on the other hand, is linked by an alpha 1,4-glycosidic bond making it an highly branched polymer. This structure is responsible for the different physical properties of the two molecules.

when a raw, shell-less egg was placed in sugar solution the egg shrank the egg was brought back to its original size by placing it it water which process does the experiment demonstrate
Answers
Answer:
A: osmosis. The egg first expanded because it was placed in a hypertonic solution (sugar water), causing the water to exit the egg to balance the higher concentration of solute outside of the egg. Placing it in fresh water creates a hypotonic environment, thereby causing water to rush back in.

which theory states that homo sapiens began in a single geographical area and spread out from there?
a. out of africa theory
b. tectonic theory
c. multi-regional theory
Answers
Answer:
The out of Africa theory states that Homo sapiens began in a single geographical area and spread out from there.
Explanation:
A is correct because the ''out of Africa theory'' suggests that the Homo sapiens began as a species in Africa and from there it gradually spread out on the other continents across the world.
B is not correct because the ''tectonic theory'' is a theory that has nothing to do with the Homo sapiens species, but it is a theory about the movement of tectonic plates.
C is not correct because the multi-regional theory suggests that the Homo sapiens evolved into multiple regions simultaneously, not in one region only.
Why can scientists compare the amino acid sequences of the proteins of three different living organisms?
A. because the genetic code is universal for all organisms
B. because the basic anatomy for all living organisms is the same
C. because RNA cannot be used to show evolutionary relationships
D. because the sequence of RNA is the same in all living organisms
Answers
Answer: A. because the genetic code is universal for all organisms
Explanation:
The genetic code of living things refers to the information that cells in living organisms use to encode genetic information from the DNA and the RNA into proteins.
Every living organism uses the same genetic code and scientists believe this is because we all share a common history in terms of evolution. This homogeneity is advantageous because it enables scientists to be able to compare amino acid sequences across multiple living species.
