Which of the following BEST describes the difference between the functions of nucleic acids and enzymes? (A) Nucleic acids inhibit biochemical reactions, while enzymes provide structural support in cells.
B) Nucleic acids contain the genetic code for protein synthesis, while enzymes catalyze chemical reactions
C) Nucleic acids are used as the building blocks of proteins, while enzymes are used as the building blocks of phospholipids
D) Nucleic acids transmit signals that begin biochemical processes, while enzymes convert carbohydrates into lipids and proteins

Answers

Answer:

B) Nucleic acids contain the genetic code for protein synthesis, while enzymes catalyze chemical reactions

The correct option is, (B) Nucleic acids contain the genetic code for protein synthesis, while enzymes catalyze chemical reactions.

Which of the following best describes the difference between functions of nucleic acids and enzymes?Nucleic acids contain the genetic code for protein synthesis, while enzymes catalyze chemical reactions. Some proteins catalyze biochemical reactions.

What is the main difference between nucleic acid and protein structure?Amino acids and nucleic acids are two categories of crucial macromolecules in the cell. The primary distinction between amino acid and nucleic acid is that amino acid is a monomer and is used to construct proteins, whereas nucleic acid is a polymer of nucleotides that stores genetic information of a cell.

What is the difference between nucleic acid and?Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.

How the functions of proteins differ from the functions of nucleic acids?Nucleic acid plays a crucial role in the storage, transmission, and utilization of the information required for life's operations. Amino acids, which are the building blocks of protein and necessary for life, are present.

Answers

Answer:

D

Explanation:

When performing low-intensity activities, the oxidative system uses fats as a substrate to produce ATP. Thus, option D is correct.

What is the significance of oxidative phosphorylation?

The majority of the ATP required for higher animals and plants to sustain life is produced by oxidative phosphorylation, which is also in charge of establishing and preserving metabolic equilibrium.

The last phase of aerobic cellular respiration is oxidative phosphorylation. The production of many ATP molecules is the primary goal of oxidative phosphorylation.

The energy system that largely supports prolonged, low-intensity exercise is sometimes referred to as the aerobic system. By boosting oxygen availability and enhancing our capacity to metabolize fat for energy, it supports this kind of exercise.

Therefore, oxidative phosphorylation take place in mitochondria.

If other people breathe the contaminated air or touch the infected surface, then touch their eyes, noses, or mouths, they can become infected.Measles is caused by a virus in the paramyxovirus family and it is normally passed through direct contact and through the air. The virus infects the respiratory tract, then spreads throughout the body. Measles is a human disease and is not known to occur in animals.

It usually begins as flat red spots that appear on the face at the hairline and spread downward to the neck, trunk, arms, legs, and feet. Small raised bumps may also appear on top of the flat red spots. The spots may become joined together as they spread from the head to the rest of the body.

Consider a cross between a plant with two flower colors, yellow and red. Yellow (Y) exhibits complete dominance over red (y). It also has either single blossoms or double blossoms, single blossoms (S) exhibit complete dominance over double blossoms (s). A dihybrid yellow, single blossomed flower is crossed with a red flowered and double blossomed plant. You observe the following phenotype frequencies among the 1545 offspring plants:
500 yellow flowers and single blossom plants
515 red flowers and double blossom plants
260 yellow flowers and double blossom plants 270 red flower and single blossom plants.
What is the recombination frequency between these two genes?
a. (260+270) 1545
b. 270/1545
c. 1545/ (260+270)
d. 260/1545
e. (500+515)/1545
f. 1545/260
g. 1545/270
From these results one can conclude that:_______.
a. the two genes are linked
b. the two genes are not linked
c. if the genes are linked, they are separated far enough apart to appear to assort independently

Answers

Answer:

1) option a is correct. (260+270)/1545

(Note about this option: In the statement, it is written as (260+270) 1545. Lacks the division symbol, / )

2) From these results one can conclude that the two genes are linked (option a)

Explanation:

To know if two genes are linked, we must observe the progeny distribution. If heterozygous individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. If we observe a different distribution, phenotypes appearing in different proportions, we can assume linked genes in the double heterozygote parent.  

We might verify which are the recombinant gametes produced by the di-hybrid, and we will be able to recognize them by looking at the phenotypes with lower frequencies in the progeny. Phenotypes with the highest frequencies represent the parental gametes.

To calculate the recombination frequency, we will use the following formula: P = Recombinant number / Total of individuals.  

In the present example:

Parental)        YySs                        x                 yyss

Gametes)  YS parental type                        ys, ys, ys, ys

                 ys parental type

                 Ys recombinant type

                 yS recombinante type

The total number of individuals in the offspring: 1545

Phenotypic class Number of offspring  

500 Y-S- (parental)515 yyss (parental)260 Y-ss (recombinant)270 yyS- (recombinant)

According to this information, the phenotypic frequencies of the progeny differ from the phenotypic ratio 1:1:1:1. We can assume then, that these genes are linked.

The recombination frequency is:

P = Recombinant number / Total of individuals

P = 260 + 270 / 1545

P = 530/1545

P = 0.343

The genetic distance between genes is 0.343 x 100= 34.4 MU.

i. Identify an environmental problem associated with large-scale intensive agriculture on soil.

Answers

The large scale intensive agriculture can strip the soil of its nutrients, leading to more unusable land, less crops, and can greatly affect wildlife

Intensive agriculture is resulting in the loss of ecosystem and is contributing to global warming.  

• An agricultural mechanization and intensification system, whose main objective is to increase the productivity from the accessible land via several means like heavy use of chemical fertilizers and pesticides is known as intensive agriculture.  

• The intensive agriculture is generally aimed to feed large population of humans, however, the method has contributed as one of the biggest threat to global environment, as it is resulting in the loss of ecosystem and global warming.  

• It is accountable for the 80 percent of the tropical deforestation and emergence of novel parasites and reemergence of the parasites, which were under control at one time.  

• The intensive farming hampers the beneficial plants and insects, and depletes and degrades the soil it relies upon.  

• It is resulting in soil erosion and is resulting in the genetic erosion of the livestock species and crops around the globe.  

Thus, intensive farming in order to feed large populations is eradicating the world agriculture slowly and gradually.

Answer: Helper T cells, or Th cells, coordinate immune responses by communicating with other cells. In most cases, T cells only recognize an antigen if it is carried on the surface of a cell by one of the body's own MHC, or major histocompatibility complex, molecules.

Explanation:

Answer:

T cells identify pathogens based on antigens on the surface of pathogens. The T cells then multiply and stimulate B cells to produce antibodies. The antibodies attach to the antigens, making the pathogens a target for phagocytes.
