Some individuals suffer from a rare genetic condition called hemophilia. This condition makes it extremely difficult for the body to stop bleeds when they occur. Which of the following blood components does a hemophiliac most likely lack?Blood plasmaErythrocytesLeukocytesThrombocytes

Answers

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

What happens to the body system in the body as a whole of homeostasis is not maintained

Many systems of the body work together to maintain estable the inner conditions of the organism such us temperature and pH. It is carefully regulated, but in case a mechanism of controll fails and homeostasis can't be maintained, cells may not receive all they need, or toxic waste may accumulate in the body. If homeostasis is not restored, the imbalance could lead to illness or even death.

In what ways are humans responsible for causing extinctions of other species?I. Destruction of habitatsII. UV radiationIII. PollutionIV. Over huntingV. Climate changeA. I, III, IV, VB. I, II, III, IVC. II, III, VD. I, II, IV

Answers

Humans are responsible for other species' extinction because over the years we have overhunted them, such as was the case of the Tanzania tiger (Thylacinus cynocephalus), and destroyed species' habitats. We have caused climate change and air and water pollution, such as happened with the industrial revolution and still with many of our today's industrial practices.

So the correct answer is the first one: A. I, III, IV, V, or destruction of habitats, pollution, overhunting, and climate change.

Which of the following describes therelationship between the barnacle and the whale?A. both organisms benefitB. one organism benefits; the other is harmedC. one organism benefits; the other is neither helped nor harmedD. neither organism benefits or is harmed

Answers

A barnacle is a marine crustacean that attachets itself to a surface and stays in the same place its whole life. They feed on plankton by sweeping the water with their fan-like feet.

In this case, the barnacle attaches itself to the whales, by doing so, these organisms do not harm the whale, but are provided of a surface where they can filter food and live without being harmed themselves.

In this relationship, one organism, the barnacle, benefits, while the other organism, the whale, remains unaffected. This type of relationship is called "commensalism"

2. Explain how small coral polyps can produce huge reefs. Then explain how a living coral comp
with a dead coral, and describe what happens to a dead reef over time. (3 points)

Answers

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.

Using the following table match the tubes to the right patients

Answers

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.

Most nutrient absorption happens in which structure within the digestive system?Question options:A) StomachB) Large intestineC) ChymeD) Duodenum

Answers

BIOLOGY > HUMAN BIOLOGY > DIGESTIVE SYSTEM

EXPLANATION:

In the mouth, physical digestion of the food happens by chewing of the food. In the stomach, the food is broken down by chemical digestion into smaller particles that can be easily absorbed by the body. It will pass through the small intestine first where the microvilli and villi are. Then, most of the undigested and unabsorbed food particles are passed through the large intestine. It will be getting secreted out of the body after.

ANSWER: D. Duodenum is the first section of the small intestine right after the pyloric sphincter.

How can you tell which organisms would have a specific trait on a cladogram?

If you looked at the range of height in humans, would you this is a polygenic trait or a simple mendelian genetic trait? Why?504030Number of people201002606570Height fin75

Answers

Looking at the continuous variations of the range of height in the graph, it can be determined that the trait is a polygenic trait.  

Continuous variation is the factor where the human height can differ to a variety of ranges. There are no clear cut distinctions of height between short, medium and tall. Also there are no fixed amount of heights in the graph. The height can vary even from a fractions of inches and that defines continuous variation.

Polygenic trait is the one which is influenced by two or more than two genes. These traits do not follow the Mendelian genetic pattern and they may also be influenced by genetic factors.

Sort the descriptions or examples into inherited or somatic mutations

Answers

The descriptions of somatic mutations are: exists in all cells of the body, skin cancer caused by UV exposure, not passed on to offspring.

The descriptions of inherited mutations are: transferred via egg and sperm cells, found only in a specific cell type.

Somatic mutations are the changes in the DNA that occur in all the cells apart from the germ cells. The change can be due to influence of environmental factors or due to exposure to some chemicals. The examples of somatic mutations are skin cancer, lung cancer, etc.

Inherited mutations are the change in the DNA of germ cells that are further passed on to the offspring. The examples are: cystic fibrosis, hemophilia, sickle cell disease, etc.

Meiosis is a life process associated with sexual reproduction which choice correctly summarizes meiosis into on statement?

Answers

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.
