name and describe the two types of food making found among autotrophs and give an example of each. Which is quantitatively more important to life on earth (which are there more of)?

Answers

Answer 1

Answer:

See the answer below

Explanation:

Autotrophs are organisms that have the capacity to manufacture their foods from freely available inorganic products. There are two types of autotrophs

1. The photosynthetic autotrophs: these are green plants and blue-green algae that possess chlorophyll. The chlorophyll is used to trap radiation from the sun in the presence of water and carbon dioxide to manufacture carbohydrates which serve as their primary foods.

[tex]6CO_2 + 6H_2O + sunlight --> C_6H_1_2O_6 + 6O_2[/tex]

2. The chemosynthetic autotrophs: these are usually bacteria that make use of energy from inorganic chemicals (such as hydrogen sulphide, iron sulphide, etc) to reduce carbon dioxide and produce carbohydrates in the process.

[tex]CO_2 + 4H_2S + O_2 -> CH_2O + 4S + 3H_2O[/tex]

Photosynthesis is quantitatively more important to life on earth because green plants form the base of several food chains. The energy locked in the carbohydrate produced during photosynthesis is important for other lives in the ecosystem and this is passed on through the various levels in the food chain. Also, the by-product of photosynthesis, the oxygen, is important for the survival of most life on earth who depends on oxygen for respiration. Chemosynthesis only occur in habitats where the radiant energy of the sun is lacking, such as hydrothermal vents.

the oxygen of air diffuses out from

Answers

Answer:

From higher concentration to lower.

Explanation:

The oxygen diffuses out from a region of higher concentration to the region of lower concentration because of diffusion. The air contain high amount of oxygen and human body has low oxygen level so the oxygen moves from the air to the lungs of the human body from there oxygen is loaded in the hemoglobin while on the other hand, carbondioxide is removed from the blood into the lungs which goes outside the body through breathing.

If Tom Harris had type AB blood and Mary had type O, could the type O child they brought home be their child? * No, the baby would have to have inherited a gene for O from both parents and Tom has only a gene for A or B. Yes, both parents had the recessive hidden gene for O blood in their genotype which they passed on to the baby. No; the baby would have to have Type AB blood that it inherited from the father since A and B are dominate to O. Yes; the baby inherited type O blood from the mother Mary Harris which is dominant to the genes for both A and B.

Answers

Explanation:

No, the baby would have to have inherited a gene for O from both parents and Tom has only a gene for A or B.

The study of blood is called hematology. The component of blood is RBC, WBC, platelets, and plasma.

The correct answer to the question is option B.

What is a blood group?A blood type is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells. These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.

The genes A and B are dominant over O therefore the O blood group can not be seen in offspring.

Hence, the correct answer to the question is option B is Yes, both parents had the recessive hidden gene for O blood in their genotype which they passed on to the baby. No; the baby would have to have Type AB blood that it inherited from the father since A and B are dominant to O.

AZT works by interfering with HIV's production of offspring inside a host cell. It does so by interacting with a molecule called reverse transcriptase.

a. True
b.False

Answers

Answer:

a. True

Explanation:

AZT is an abbreviation for azidothymidine and it is the first effective drug against the human immunodeficiency virus (HIV). Thus, azidothymidine is considered to be the first anti-retroviral drug used for the prevention and treatment of the human immunodeficiency virus (HIV).

AZT works by interfering with HIV's production of offspring inside a host cell. It does so by interacting with a molecule called reverse transcriptase.

Basically, the shape and composition of the reverse transcriptase plays a significant role in the interaction. Therefore, this anti-retroviral drug known as AZT may not work effectively if the shape and composition of the reverse transcriptase changes.

Furthermore, the high mutation or replication rate of the human immunodeficiency virus (HIV) owing to its enormous genetic diversity has made it extremely difficult to develop an effective and accurate vaccine against the virus.

Hence, the human immunodeficiency virus (HIV) possesses a high error rate.

D. Ozone holes have more ozone than usual.

E. Ozone holes can be hole-shaped.

F. There is always just one ozone hole in the Earth's atmosphere.

Answers

Answer:

Ozone holes have more ozone than usual.

Correct Answer

Ozone holes allow ultraviolet light to reach the Earth's surface.

Ozone holes don't have any ozone in them.

Chlorofluorocarbons make an ozone hole larger.

Explanation:

Ozone has been the atmospheric layer that protects the earth. It allows the ultraviolet rays to enter the earth, and there is one ozone hole due to the Chlorofluorocarbons. Thus, options B, C, and F are correct.

What is an ozone hole?

An ozone layer is defined by the presence of the ozone gas that is present in the atmosphere of the earth. The ozone hole is the hole in the ozone layer that is due to the depletion of the ozone gas in the layer due to increased global warming and pollution.

The increased concentration of Chlorofluorocarbons (CFCs) generated from aerosols, air conditioners, and refrigerants have resulted in a hole in the ozone layer. This lead to increased exposure of the organism to the harmful UV radiations emitted from the sun.

Also, this has resulted in increased climatic changes because of the global warming and heating of the atmosphere due to the entrapment of the UV and Sun rays. This leads to various diseases including cancer and eye irritation.

Therefore, the ozone hole is due to increased Chlorofluorocarbons. options B, C, and F are correct.

Bloom syndrome is an autosomal recessive disease that exhibits haploinsufficiency. A recent survey showed that people heterozygous for mutations at the BLM locus are at increased risk of colon cancer. Suppose you are a genetic counselor. A young woman is referred to you whose mother has Bloom syndrome; the young woman's father has no family history of Bloom syndrome. The young woman asks whether she is likely to experience any other health problems associated with her family history of Bloom syndrome. What advice would you give her?

Answers

Answer:

The correct answer is - she is heterozygous for a mutated BLM allele and will have an increased risk of colon cancer.

Explanation:

Autosomal recessive disease expresses itself in next-generation only if there is both alleles are recessive for the gene. In haploinsufficiency, the dominant allele fails to express itself in the phenotype due to insufficiency. So, if even one allele of the recessive gene present in the haploinsufficiency case, it will affect and express its trait.

She is heterozygous for a blood syndrome, as her mother had but her father has no disease, allele and will have an increased risk of colon cancer.
