Answer:

I believe these are called homologous structures.

Explanation:

Homologous structures are similar to each other and likely descend from common ancestors.

The tilt in the axis of the Earth is called its obliquity. This angle changes with time, and over about 41 000 years it moves from 22.1 degrees to 24.5 degrees and back again. When the angle increases the summers become warmer and the winters become colder.anation:

Answer:the diagram illustrates the results of non disjunction during gamete formation.

Explanation:

The following statements concerning the karyotype in the diagram is true - The diagram illustrates the results of nondisjunction during gamete formation.

Karyotype refers to the number and appearance of chromosomes present within the nucleus of a eukaryotic cell. It is illustrated as a diagram such as given in the question.

There is no Down's syndrome as the karyotype demonstrates a normal pair of chromosome 21.  In this karyotype, there is an extra X-chromosome that depicts non-disjunction during either oogenesis or spermatogenesis (gamete formation) in the parents leading to the 23rd trisomy.

Answer:

Here, we have a composition passage and we are required to fill in the with missing words. The missing words are highlighted in bold format and underlined.

Lecithins and cephalins are both glycerophospholipids; they consist of glycerol with fatty acids forming ester bonds with the first and second hydroxyl groups. The third hydroxyl group of the glycerol forms a phosphate bond with phosphoric acid, which forms another phosphate bond with an amino alcohol. In lecithins, the amino alcohol is choline; in cephalins, the amino alcohol is usually ethanolamine.

Explanation:

Lecithin is a chemical complex composed primarily of fatty acids, glycerol, phosphoric acid, and choline. It can be present in egg yolks, soybeans, sunflower seeds, and plant seed cells and is completely normal. Soybean and sunflower lecithins contain much more important fatty acids than rapeseed lecithin, making them nutritionally more useful.

Phosphatidylethanolamine, also known as cephalin, is a phosphoglyceride that, like phosphatidylcholines and lecithins, is a component of biological membranes. A glycerol residue esterified by two fatty acids and a phosphoethanolamine residue gives rise to phosphatidylethanolamines. They're made by combining CDP-ethanolamine with diglycerides and releasing a CMP molecule. Phosphatidylcholines are formed when S-adenosylmethionine methylates the amine in ethanolamines. They're mostly found in the inner layer of plasma membranes' lipid bilayers.

Explanation:

We grouped the lizards into various groups on the basis of similarities and differences in the body structure, appearance and colour etc. The legs of anole lizards are small legs with pads on their feet for gripping surfaces which give them the advantage to climb up the trees while on the other hand, these small legs can't help in the survival on the land because they can't run too fast from their predators with these short legs so these legs has benefit in climbing the tree but disadvantage in running on the land.

Answer:

Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.

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.

The part of the plant that produces fruit and seeds is the pistil. The Pistil is the ovule producing part of a flower, where a mature ovary is a fruit, and the mature ovule is a seed.

Seeds may be defined as the unit of reproduction of a flowering plant, capable of developing into another such plant.

Flowers are the parts of the plant that are responsible for the production of fruits and seeds. The part of the flower that becomes a fruit is called the ovary.

Therefore, the part of the plant that produces fruit and seeds is the pistil.

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.
