Some people have one sickle cell gene and one normal gene. They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the human system of reproduction result in people getting one copy of a sickle cell gene and one copy of a normal gene? Describe the process.

Answers

Answer 1

Answer:

Through meiosis

Please find the description below

Explanation:

Humans reproduce via a type of reproduction called SEXUAL REPRODUCTION. Sexual reproduction is the type of reproduction that involves two sexes (male and female) of an organism. The males produces male gametes called SPERM while females produce female gametes called EGG.

The process by which these gametes is produced is called MEIOSIS. Meiosis is a division that reduces the chromosome number of the parent cells. According to Gregor Mendel, it occurs in such a way only one allele of a gene is present in each gamete.

Hence, according to this question, getting one copy of a sickle cell gene and one copy of a normal gene is as a result of meiotic division of male and female. One parent undergoes meiosis and contributes the normal allele (S) while the other parent undergoes meiosis and contribute the sickle allele (s).

Glucose consists of carbon, oxygen and hydrogen atoms. What happens to these atoms
during glycolysis?
a) Nothing, glycolysis does not affect the glucose molecule
b) The atoms are converted into other molecules in a series of chemical reactions
c) The atoms are transformed into energy
d) All atoms are transformed into other atoms in a series of chemical reactions

Answers

Answer:

b.

Explanation:

the atoms are converted into other molecules (pyruvate) in a series of chemical reactions

Glucose consists of carbon, oxygen and hydrogen atoms. The thing that happens to these atoms  during glycolysi is that The atoms are transformed into energy

Glucose is a type of simple sugar that has six carbon atoms and during glycolysis, is broken down easily because it is a monosaccharide

Glycolysis is the process of breaking down and converting glucose into CH₃COCOOH.

Therefore, what happens to carbon, oxygen and hydrogen atoms during glycolysis is that they are transformed to energy

James examines a cell from an aloe plant and a cell from an owl feather. Which structure is found only in the cell from the aloe plant?
O A. chloroplast
OB. membrane
O C. mitochondrion
O D. nucleus

Answers

I’m thinking it’s A. Chloroplast

The chloroplast will only be found inside the Aloy plant while other structures will be shared by both cells. Option A is correct.

Difference between Plant and animal cells:Both plant cell animal cells are eukaryotic cells, but both have some unique structures.Plants have a cell wall but animals just have a cell membrane.A plant cell has a chloroplast for photosynthesis while an animal cell does not have a chloroplast.

Since owl is an animal and Aloy is a plant

Therefore, the chloroplast will only be found inside the Aloy plant while other structures will be shared by both cells.

Name the ionic compound of Cu2(SO4)3?

Answers

Answer:

cuprous sulfate

Explanation:

Copper(I) sulfate, also known as cuprous sulfate and dicopper sulfate, is the chemical compound with the chemical formula Cu2SO4 and a molar mass of 223.15 g mol−1. It is an unstable compound as copper(I) compounds are generally unstable and are more commonly found in the CuSO4 state.

Hope this helped :)

The name of the given compound Cu₂(SO₄)₃ is copper (I) sulfate.

To name the given compound, first determine the oxidation number of copper in the compound as shown below;

[tex]Cu^{2+} \ + \ (SO_4)^{2-}[/tex]

2x = 2

x = +1

The compound can now be named starting with copper followed by its oxidation number, the lastly is the radical. The radical is sulfate.

Thus, the name of the given compound Cu₂(SO₄)₃ is copper (I) sulfate.

Chloroplasts and Mitochondria are two organelles that are largely
responsible for the cycling of carbon through the ecosystems. What are
their functions?

Answers

Function for Mitochondria - Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Function for Chloroplast - In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

Which sediment would have the slowest rate of deposition?
a round sediment
O a very large sediment
an irregularly shaped sediment
O a high-density sediment

Answers

Answer:

C. An irregularly shaped sediment

Explanation:

Deposition is the settling of sediments within respective basins of deposition.

Irregularly shaped sediments are the slowest to settle within a basin this is due to the frictional resistance of their surface.

As these particles hits the water, the liquid drag on their edges is very great and prevents swift settling.

A. A high density sediment and a large sediment will have a fast settling time.

B. Rounded sediments will impose no friction on the water and they fall through the liquid very fast.

Answer:

the answer is C. an irregulary shaped sediment
