Answer:

The sickle-cell gene.

Explanation:

The sickle cell mutation is in the gene encoding the β subunit. The sickle cell gene is located on the short arm (p) of chromosome 11, at position 15.5. Sickle cell anemia is a genopathy caused by a single mutation that results in the substitution of an amino acid in the β chains of the tetrameric protein hemoglobin. It characterized by the presence of sickle cells in the bloodstream, which are red cells or sickle-shaped erythrocytes. This form causes difficulty in the circulation of red blood cells. Confirmation of sickle cell anemia is obtained through tests that determine the presence and relative amount of hemoglobin S in a blood sample, that is, by checking the phenomenon of sickle cell disease, in a drop of blood between the slide and covers objects, or the presence of hemoglobin S by means of electrophoresis.

5. Consider a system consisting of an egg in an incubator. The white and yolk of the egg contain proteins, carbohydrates, and lipids. If fertilized, the egg is transformed from a single cell to a complex organism. Discuss this irreversible process in terms of the entropy changes in the system, surroundings, and universe. Be sure that you first clearly define the system and surroundings.

Answers

Answer:

According to the question, we could consider the developing chick as the system and the surrounding of this system would be nutrients, external environment, or world and eggshell that affects the system. The entropy of the system decreases with the transformation of the development of the cell into a chick drastically.

In this system initially, it has a low entropy condition as it the surrounding have complex fuel molecule compare to the system, however, during the period of incubation the complex molecule of surrounding fuel release in the high quantity of CO2 and water molecules and leads to the higher entropy of surrounding than the decrease in the entropy of the system.

Explanation:Durante la respiración celular, una molécula de glucosa se degrada poco a poco en dióxido de carbono y agua. Al mismo tiempo, se produce directamente un poco de ATP en las reacciones que transforman a la glucosa. No obstante, más tarde se produce mucho más ATP en un proceso llamado fosforilación oxidativa.Las células procariotas llevan a cabo la respiración celular dentro del citoplasma o en las superficies internas de las células. Aquí se hará mayor hincapié en las células eucariotas, en donde las mitocondrias, son el lugar donde se produce la mayoría de las reacciones.

12. Traits are determined by the proteins that are synthesized according to instructions coded in DNA. Which sequence of biomolecules is responsible for the coded instructions?

A enzymes
B nucleotides
C glycoproteins
D carbohydrates

Answers

Answer:

B. nucleotides

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.

Basically, nucleotide comprises of the following parts;

1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.

2. A phosphate group.

3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.

The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;

I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.

II. Phosphate: this is the structural backbone that provides support to DNA.

In conclusion, the proteins which are mainly synthesized based on the genetic instruction codes in deoxyribonucleic acid (DNA) determines the trait of living organisms. A sequence of biomolecules which are responsible for this coded genetic instructions in all living organisms is known as nucleotides.

(C) Humans are more closely related to rabbits than they are to rhesus monkeys. (D) Plants and animals have no similarities at all. (E) Mammals are more closely related to reptiles than they are to fish.

Answers

Complete question:

A scientist used the amino acid sequence of cytochrome c in different species to consider evolutionary relationships.

The data below summarizes the numbers of differences in the amino acid sequences of cytochrome C found in the selected species

Species compared              Number of differences

Human-chimpanzees                              0

Human-Rhesus monkeys                        1

Human-Horses or Donkeys                    7

Human-Cow, Pigs or sheeps                  7

Human-Rabbits                                        7

Mammals-Birds and reptiles                  10-15

Mammals-Fishes                                    18-20

Mammals-Plants                                     45-48

Interpretation of the data supports which of the following statements?

(A) Rhesus monkeys are more closely related to rabbits than they are to horses.

(B) Horses and cows have identical amino acid sequences in their cytochrome c.

(C) Humans are more closely related to rabbits than they are to rhesus monkeys.

(D) Plants and animals have no similarities at all.

(E) Mammals are more closely related to reptiles than they are to fish.

Answer:

(E) Mammals are more closely related to reptiles than they are to fish.

Explanation:

So, what you need to do here is to compare the number of differences found in each comparison. Remember that this information is only regarding cytochrome C. For instance, we can see that between humans and chimpanzees, the number of differences is 0. Their amino acid sequences do not differ at all. On the contrary, the comparison of mammals and plants threw a value of 45-48 differences, meaning that they are very different from each other, almost 50%.

So, this is how you need to interpret the values of the differences in this table. Now, let us go to the options,

(A) Rhesus monkeys are more closely related to rabbits than they are to horses. Rhesus monkey was not compared to any group other than humans, so we could not say that they are more related to one animal or the other.

(B) Horses and cows have identical amino acid sequences in their cytochrome. When comparing humans with horses and then humans with cows, the number of differences was the same -7-. But these results do not indicate which are the differences. Remember that we are comparing amino acid sequences, so probably the number of differences of each group with humans is the same, but the amino acid sequences between horses and cows are not.

(C) Humans are more closely related to rabbits than they are to rhesus monkeys. Humans and rhesus monkeys express only one difference in the amino acid sequence, while humans and rabbits exhibit seven differences. This result means that humans are more closely to rhesus monkeys related than they are to rabbits.

(D) Plants and animals have no similarities at all.

As we mentioned before, plants and mammals have a difference of almost 50% in their amino-acidic sequences. It does not mean that the other 50% is also different.

(E) Mammals are more closely related to reptiles than they are to fish.

The amino acid sequence of mammals and reptiles show 10-15 differences

The amino acid sequence of mammals and fish show 18-20 differences

So yes, mammals seem to be more related to reptiles than to fishes because the number of differences with reptiles is fewer.

D)
D = 02 + C6H1206
E)
B = 02 + C6H1206

Answers

Answer:

A) A = ATP

B) B = CO2 + H2O

D) D = O2 + C6H12O6

Explanation:

The process of photosynthesis and cellular respiration mutually depends on one another. In this diagram, A represents ATP, B represents C[tex]O_2[/tex] + [tex]H_2O[/tex], C represents sunlight, and D represents [tex]C_6H_1_2O_6 + O_2[/tex].

What do you mean by Photosynthesis?

Photosynthesis may be defined as a process through which plants synthesize their own food with the help of carbon dioxide and water in the presence of sunlight.

Mitochondria release energy in form of ATP, while carbon dioxide and water serve as the reactant for photosynthesis. In presence of sunlight, they convert into glucose and oxygen which is the product of photosynthesis.  

Both photosynthesis and cellular respiration mediate the cycling of matter like oxygen, glucose, carbon dioxide, etc.

Therefore, it is well described above.
