Okay, we can see that parents in the image have a 4 puppies' offspring, all of them with spotted fur (SS or Ss). So the genotypes of each parent must be ss for the white-furred parent and SS for the spotted furred parent.

Building of new housing, cities, or factories is not a cause of habitat loss.

What is habitat loss?

Destruction of habitat is the process by which a natural habitat becomes unsuitable for its native species. Former inhabitants of the site have been displaced or eliminated, resulting in a decrease in biodiversity and species abundance. Destruction of habitats is the major cause of biodiversity loss.

Natural causes of desforestation (natural and cyclical events):

- Fires (because of climate or heat waves);

- Floods (because of climate changes and storms);

- Hurricanes (because of natural events).

Human related causes of desforestation (human activity):

- Activities as agricutural expansion;

- Oil extraction;

- Infrastructure development;

- Mining;

- Construction;

- Cattle breeding.

Let's analyze each one of the postulates and compare to the options.

1. A pathogen must be found in the body of a sick person.

This one states the same as the option A, therefore option A is not the answer.

2. A pathogen must be isolated and grown in a lab culture.

This one states the same as the option B, therefore option B is not the answer.

3. The pathogens that were created in this lab culture, when introduced in a healthy person's body, must give the disease to this person.

This one states the same as the option C, therefore option C is not the answer.

4. The pathogen must be isolated again and must be the same as the original.

This one states that the last isolated pathogen must be equal to the original one, but option D states that it must be mutated, which means that it would be different than the original. Therefore, option D is incorrect.

The correct answer is D. 4.The pathogen should be isolated again and should have mutated when compared to the original.

Biodiversity is important for ecosystem health because it is a essential for the support all life on the planet, being the wide range of living organisms necessary for provide a functioning environment, since all the organisms and resources are important for life, like oxygen, water, food, and so on. Without plant diversity there is less oxygen, as well less organisms in the overall food chain and so on, because of that the ecologists consider it a important factor for ecosystem health.

The Central Nervous System (CNS) is of vital importance, meaning that any small trauma that it may suffer can represent a death risk for the individual. This lead natural selection to cause the organisms to develop a strong protection against those traumas. The Peripheral Nervous System (PNS) is of monumental importance, but the traumas suffered has local impact only. The PNS is also spreaded through the entire body, getting to the tip of our toes and fingers. Therefore, its evolutionary development didn't involve the need of having such a strong protection, and that would have been really difficult as the PNS is so widely spreaded throughout the body.

We have the following information about the patients:

A) Healthy 40-year-old man

B) 18-year-old girl with chronic lung infections

C) History of anemia

And for each tube, we have the values for hemoglobin and leucocytes.

Hemoglobin is found in the red blood cells and helps carry oxygen, so a person with anemia would have low levels of hemoglobin.

In this case, tube 3 has the lowest levels of hemoglobin, out of range for both males and females, so we can say it belongs to patient C.

This leaves us with tubes 1 and 2.

If we see the levels of hemoglobin, tube 1 has lower levels of hemoglobin than tube 2, which suggests that tube 1 belongs to a female and tube 2 to a male.

But we also have to take into account the leucocyte, which would be elevated in the case of an infection. If you look at this, tube 1 has elevated leucocytes.

Combined, this information tells us that tube 1 belongs to patient B and tube 2 belongs to patient A.

Answer: Hypothalamus

Explanation:

Stony coral polyps can create massive reef structures because polyps secrete skeletons of calcium carbonate (CaCO3).

Most stony corals have very small polyps, averaging 1 to 3 millimeters in diameter, when they grow large they forms colonies that can grow and weigh upto tons.

Coral polyps feed on microscopic algae called zooplankton. All the polyp then secretes an exoskeleton made out of limestone (CaCo3). These exoskeletons join together to form a coral colony which forms a coral reef. with due course of time, as the calcium carbonate builds up and corals reproduce, the size of a coral reef grows.

B. Sexual and asexual reproduction.

• Scientific name and identification: ,Lycosa erythrognatha,.

This spider is distributed in Brazil, Argentina, Uruguay, and Paraguay.

It can be active during the day or night and is often found in cities, especially in gardens.

The spider is at the 3rd trophic level and is a secondary consumer (the spider feeds on beetles, butterflies, and flies and does not use its web to capture, but uses it to trap its prey).

The wolf spider can be present in much of South America and so it can be found in Biomes such as Temperate Forest and Tropical Forest.

Solution:

People that born with hemophilia lack or have a low amount of a clotting factor.

Coagulation factors are proteins necessary for normal blood clotting.

Coagulation factors are found in blood plasma. These factors act with Thrombocytes to clot blood.

However, hemophilia is not a decrease in Thrombocytes but a decrease in coagulation factors due to genetic causes.

Diagnosis includes screening tests and clotting factor analysis. Screening tests are blood tests that show whether the blood is clotting properly. Clotting factor tests can reveal a deficiency of clotting factors in the blood plasma and determine the level of severity of hemophilia.

As the coagulation factors are in Blood plasma, we can conclude that the correct answer is:

BLOOD PLASMA

1. The DNA in saliva comes from the cells that are shed from the inner linings of the mouth and the white blood cells.

The correct option is the second one, Endosymbiotic theory. This theory, posits that a bigger prokaryote ate a smaller one, which eventually lost its independence an become an organelle, giving rise to the first eukaryote.

In many cases, organisms' traits help to establish ancestry relationships and allow to elucidate evolutive history, now in cladograms when organisms share ancestry it implies that that group of species share a specific set of traits. In other words those organisms that belong to the same branch will share a set of traits.

The answer is C. P wave occurs after the QRS complex but before the T wave.

Solution:

Remember that Electrophoresis separates macromolecules by size, charge, and other properties.

Buffers in gel electrophoresis are used to generate ions and thus carry a current flow (transmit a charge through the gel) Also, let's remember that a buffer is a substance that keeps pH levels stable. Therefore, buffers in gel electrophoresis are used to maintain the pH at a relatively constant value.

After the cells perform all the previous processes of the cell cycle, at the end of them, it results in two daughter cells for mitosis and meiosis I, and four daughter cells for meiosis II. This is accomplished because the cell uses proteins such as actin and myosin to enclose the resulting nuclei and the different organelles of each cell. We can say then that the correct answer is the second one: cytokinesis, and this can be seen with a little more detail in the picture below at the right part of it.

Mitosis is a cellular division that produces two diploid cells from a parent cell. Meiosis is a cellular division that produces four haploid cells from a parent cell. Mitosis is observed in somatic cells while meiosis is observed in gametes/sex cells.

ANSWER: C.

We have to find those codons which don't codes for the same amino acid, so we can do the following:

Meiosis is a process where a single cell divides twice to produce other new cells containing half of the original amount of genetic information (haploid daughter cells). They are know as our sex cells (eggs and sperm), and for all the organisms who have sexual reproduction. The meiosis can be divided into nine stages, these stages are:

Meiosis I

- Interphase

- Prophase I

- Metaphase I

- Anaphase I

- Telophase I and cytokinesis

Meiosis II

- Prophase II

- Metaphase II

- Anaphase II

- Telophase II and cytokinesis

The meiosis is also divided in two parts. The first part (meiosis I) is when one cell divides into two, and the second (meiosis II) these daughter cells are diveded into four granddaughter cells.

The cell membrane is a lipid bilayer with a hydrophilic exterior and a hydrophobic interior is a fluid membrane that allows the movement of different molecules, along the membrane but also through it.

Some molecules that can pass through the membrane are small hydrophobic molecules, such as small non-polar molecules (A); in contrast, ions and polar molecules can't cross the membrane.
