If a person were fasting and hadn't eaten for several days in a row, which source of energy would the body use as a
last resort?

Answers

Answer 1
Answer:

Final answer:

During fasting, the body uses glycogen, lipids, and protein as sources of energy.


Explanation:

When a person is fasting and hasn't eaten for several days in a row, the body relies on stored energy sources. The body first depletes its glycogen stores, which are stored in the liver and muscles, and then moves onto using fatty acids from lipids as a source of energy. Once the fat reserves are depleted, the body will turn to using protein as a last resort for energy.

Scientist can determine the age of ancient objects by a method called radiocarbon dating. The bombardment of the upper atmosphere by cosmic rays converts nitrogen to a radioactive isotope of carbon, 14C, with a half-life of about 5730 years. Vegetation absorbs carbon dioxide through the atmosphere and animal life assimilates 14C through food chains. When a plant or animal dies, it stops replacing its carbon and the amount of 14C begins to decrease through radioactive decay. Therefore, the level of radioactivity must also decay exponentially. A parchment fragment was discovered that had about 64% as much 14C radioactivity as does plant material on Earth today. Estimate the age of the parchment.

In chickens, comb shape is determined by alleles at two loci (R, r and P, p). A walnut comb is produced when at least one dominant allele R is present at one locus and at least one dominant allele P is present at a second locus (genotype R_ P_). A rose comb is produced when at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus (genotype R_ pp). A pea comb is produced when two recessive alleles are present at the first locus and at least one dominant allele is present at the second (genotype rr P_). If two recessive alleles are present at the first and at the second locus (rr pp), a single comb is produced. A walnut is crossed with a pea chicken and the offspring consists of 3/8 walnut, 3/8 pea, 1/8 rose and 1/8 single. What are the probable genotypes of the parents

Brainstorm and create a list of 4 human activities that interfere with ecosystems, food chains and food webs. For each explain how it happens, why we do it, and mention short and long term effects

Answers

Answer:

The humans are the dominant consumers. They influence food chains and food web through agriculture, production of energy, habitat destruction, pollution, hunting, and overfishing. This is generally done in order to fulfill the demands for food and shelter along with the growth of population. In long term, it influences aquatic and soil ecosystems.  

In case if due to human activities if one community of animals gets extinct then there will be a chain reaction of animals getting extinct. The animals live in harmony to thrive and without which it will proliferate into more extinct animals. Ultimately the majority of the animals will no longer be alive.  
here are some things that interfer with the ecosystem (highways, driving cars, fossil fuel, cities, farms, deforestation, over hunting, over fishing and plastics)

List and describe the function of each of the four components of blood.

Answers

Answer:

The four components of blood are RBC, WBC, Platelets, and blood plasma.

Explanation:

The major 4 components of blood are RBC, WBC, platelets, and plasma. Plasma is the fluid part of the blood and the remaining 3 are the cellular part.  

Plasma is the yellow color liquid. In the plasma, all cellular components float. Plasma constitutes approximately 55% of the total volume of the blood.

The various functions of plasma are - It carries different nutrients from the alimentary canal to the liver and other parts of the body. Simultaneously it carries the CO2 from the different tissues and reaches them to lungs for expiration. It distributes the hormones and vitamins from endocrine glands to different target organs. Plasma also plays a role in the water balance in the body. It supplies water to tissues and receives excess water from them. Thus regulate the water balance in the body.

RBC is the enucleated cellular organelle of blood. The absence of nucleus enables it to carry more oxygen. It is red due to the presence of Hb and carries O2 and CO2 in the form of oxyhemoglobin and carbaminohemoglobin. It also helps in releasing energy through the metabolic process.

WBC is concerned with the immunity of the body. It acts as a defense mechanism of the body. The components of leukocytes such as granulocytes and agranulocytes are phagocytic. They engulf bacteria and viruses. Eosinophils fight against the allergic reaction in the body.

The blood platelets have blood clotting factors. There are 12 blood clotting factors which help in the clotting of blood.

8. In an attempt to breed winter barley that is resistant to barley mild mosaic virus, agricultural researchers cross a susceptible domesticated strain with a resistant wild strain. The F1 plants are all susceptible, but when the F1 plants are crossed with each other, some of the F2 individuals are resistant. Is the resistance allele recessive or dominant? How do you know?

Answers

Answer:

The resistance allele is recessive

Explanation:

According to Darwin's pea experiment, the recessive trait appeared after a few generations.

Here in this case too the resistant individuals appeared after the first generation. This also implies that the offspring of first generation must be carrier of this recessive trait.

Let the susceptible domesticated strain  trait be represented by "S"

and the recessive resistant wild  strain trait be represented by "s"

Then,

F1 generation

SS * ss

Ss, Ss, Ss, Ss ------ All are heterozygous susceptible individuals

F2 generation

Ss * Ss

SS, Ss, Ss, ss

ss shows reappearance of resistant wild  trait.

Hence, the resistance allele is recessive.
