What is RNA ?

What is replication?

Answers

Answer 1

Answer:

ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.

Answer 2

Answer:

Ribose, found in RNA, is a "normal" sugar, with one oxygen atom attached to each carbon atom. Deoxyribose, found in DNA, is a modified sugar, lacking one oxygen atom (hence the name "deoxy"). In ribose, carbon atom #2 carries one hydroxyl group (colored red).

RNA is a ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.

how do the weight of objects on earth compare the weight of the objects on the moon why do you think this is

Answers

Answer:

Being that the moon has a gravitational force of 1.622m/s 2, we multiply the object's mass by this quantity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.

Explanation:

hope this helps you out love!! <3

Answer:

weight of objects on EARTH> weight of objects on MOON

Explanation:

weight= mass * gravity

assuming both objects have the same mass, the environment with greater gravity will result in a greater weight

gravity of earth > gravity on the moon

so

weight of objects on EARTH> weight of objects on MOON

Trilobites appeared approximately 521 years ago and disappeared approximately 250 million years ago. During which era did the trilobites live?

a
Cenozoic
b
Mesozoic
c
Paleozoic
d
None of These

Answers

Answer:

C. Paleozoic

Explanation:

Trilobites are a group of extinct marine arthropods. Just like many animals from today, including crustaceans, spiders, and insects, they belonged to the phylum Arthropoda. They lived in the Paleozoic era.

We can make this conclusion based on the fact that the period they existed in (from 521 to 250 million years ago) mostly fits the period described as Paleozoic (from 541 to 252 million years ago). However, we can see that they went extinct in the Mesozoic (250 million years ago is more than 252 million years ago). Compared to the entire time they existed, 2 million years is a relatively small amount of time, which makes Paleozoic the correct option.

Adaptations that help an organism survive appear quickly. True or False? And why

Answers

Answer:

false

Explanation:

is not worth it to do that

According to the theory of natural selection, features that may be passed down help animals adapt to their surroundings more successfully than their kin.

What condition that make organism adaptive?

Adaptations are passable traits that improve an organism's capacity to endure and procreate in a given environment. An organism can manage in harsh settings, locate food and water, and protect itself by adapting.

This is the outcome of a process called natural selection. A species' nature gradually changes as a result of natural selection in order for it to fit into the niche.

If a species becomes extraordinarily well adapted to its habitat and the environment does not change, it can survive for a very long time before going extinct.

Therefore, it is false that, Adaptations that help an organism survive appear quickly.

Most enzymes are proteins. Many cells make and use an enzyme called catalase to facilitate the decomposition of hydrogen peroxide (H2O2). The products of the decomposition are hydrogen (H2) and oxygen (O2). Stephanie is investigating the structure and function of catalase, and she is comparing catalase to other proteins. What can Stephanie predict will distinguish the structure of catalase from the structures of the other proteins she is studying? A. many regions made entirely of hydrogen and oxygen B. the chemical properties of the peptide bonds C. the types of amino acids it contains D. the sequence of amino acids it contains

Answers

Answer:

The correct answer is - B. the chemical properties of the peptide bonds.

Explanation:

The difference between the structures of catalase from other proteins depends on the chemical properties of the peptide bonds present in between the amino acids which decide the pH and temperature by their disruption. These bonds present between two alpha-amino acids when carboxyl of one amino acid interacts with the amino group of the other to form an amide-type covalent bond.

A

concentration to a lower concentration
8
endocytosis, because protein pumps transport substances that are too large to
pass through the cell membrane
active transport, because protein pumps are needed to move substances against a
concentration difference
D
osmosis, because protein pumps allow water to cross the cell membrane

Answers

Answer:

C. active transport, because protein pumps are needed to move substances against a concentration difference

Explanation:

There are two major types of transport in living cells namely: passive transport and active transport. The passive transport moves molecules down a concentration gradient and hence, do not need energy (ATP) to occur. However, on the other hand, ACTIVE TRANSPORT moves substances against their concentration gradient, thus, require energy input.

Active transport makes use of PROTEIN PUMPS to achieve this process. Hence, in this case where Alexis is using models of the cell membrane to compare the types of cellular transport. The model that shows a molecule entering through a protein pump is modelling ACTIVE TRANSPORT.

If a father has type A blood and the mother has Type AB blood, they would NOT have a child with which of the following blood types?

AB

A

B

O

Answers

Answer:

If a father has type A blood and the mother has type AB blood, they cannot have a child with blood type O, although depending on the father's genotype, they may not have children with a B blood type either.

Explanation:

Blood type is determined by the presence or absence of surface antigens A and B, which is genetically determined and establishes the pattern of inheritance.

Alleles that define the presence of antigens A and B are co-dominant, while the absence of antigens - as in blood type O - is a recessive trait.

Type A contains antigen A and its genotype can be A|A or A|O. Type B contains the B antigen, whose genotype can be B|B or B|O. Blood type AB contains both antigens and a single genotypic expression A|B Type O blood lacks surface antigens, with genotype O|O.

The father with blood type A can have two genotypes, A|A or A|O, which raises 2 possible scenarios:

1. Father A|O with mother A|B

Alleles       A         O

A              A|A      A|O

B              A|B      B|O

In this case there is no chance of having a child with blood type O, 50% chance of having children with blood type A, 25% B and 25% AB.

2. Father A|A with mother A|B

Alleles        A        A

A               A|A     A|A

B               A|B     A|B

50% chance of having a child with blood type A and 50% with blood type AB. In this case there is no chance of having children with blood type O or B.

Which of these is a characteristic of sexual reproduction?A)It takes place in all cells of the body.B)It forms exact copies of the parent cell.C)It results in offspring with genetic variation.D)It requires only one parent to form a daughter cell.

Answers

Answer/Explanation:

It results in offspring with genetic variation. 2 different mates must be used in sexual reproduction. This is because each person is different since cells are produced and combined differently in the original offsprings. If the two adults were exactly the same, the offspring would have the exact same cell traits. Likewise will be done for the offspring of the two adults. The genes may be similiar to the ones of the adults, but since combined it will not be an exact replica. In the long run sexual reproduction will result in an offspring with slightly different traits or genetic variation.

Answer:

1. ATP

Explanation:

Cellular respiration produces ATP. Thus, the correct option is C. To produce starch, glucose molecules bond together through dehydration synthesis. Thus, the correct option is C.The process through which yeast produces the carbon dioxide responsible for bread rising is known as glycolysis. Thus, the correct option is B. A component of amino acid that is not contained in starch is nitrogen. Thus, the correct option is D. Photosynthesis and nitrate absorption are the two processes that provide the glucose and nitrogen used to form amino acids in plants. Thus, the correct option is A.

What is Cellular respiration?

Cellular respiration may be defined as the chemical process of breakdown of food in the cell with the liberation of energy in the form of ATP.

Photosynthesis is a chemical process through which green plants most photosynthetic algae synthesize their own food in the form of glucose. While nitrate absorption is the process through which nitrogen in the soil is significantly absorbed by the root of plants in form of nitrates.

Fermentation is initiated with the process of glycolysis, but it does not involve the upcoming two stages of aerobic cellular respiration such as the Krebs cycle and oxidative phosphorylation.

Therefore, each of the above questions is well described above.
