Marfan syndrome is caused by a defect in FBN1 gene located on chromosome 15. The gene normally encodes the fibrilllin-1, which is important for the elasticity and appropriate growth of connective tissue. The defect in the gene that causes Marfan syndrome results in a decrease in the amount of functional fibrillin-1 produced. One defective copy of the gene is sufficient to cause Marfan syndrome.

Answers

Answer 1

Marfan syndrome is an autosomal dominant condition.

What is Marfan Syndrome?

Connective tissue, or the fibers that support and anchor your organs and other body components, is harmed by Marfan syndrome, a genetic disorder. Most frequently, the heart, eyes, blood arteries, and skeleton are impacted by Marfan syndrome.

It happens because one healthy copy of the FBN1 gene is not sufficient to sustain the normal development of connective tissue.

2. What can you infer from the fact that ants make up
20 percent of the mass of all land animals combined?
a. Ants are very heavy
b. Ants live for a long time
c. Ants thrive in locations all over the world
d. Ants breed faster than any other organism on earth

Answers

D, because they are not heavy, so if they form 20 percent of the mass of all land animals combined it means that there are many ants in the world due to the fast breed

Ant breed faster than any other organism on earth, 20% of earth mass have land animals. Many ants are on the earth. Thus, option D is correct.  

What are the major features of ants ?

Ants belongs to Formicide family  which is related to so called eusocial insects like bees and termites. It is appeared in the Cretaceous period that is more than 90 million years ago.

The diversity of ants is every where except Antarctica.

The body has three parts such as  a head, a meso-some and metasoma or gaster.

Ants are mostly omnivorous but can be scavengers , predators or herbivores based on ecological context.

The reproduction in which young, queens  fly during mating time, fertilize with male, this flight is called as nuptial flight.

Then queen lay eggs, then larvae emerge to become pupae, then adults such as workers, soldiers, males or other queens are produced.

Thus, option D is correct.

How do you think about the invention of the microscope? Influenced the cell theory?
And what are the components of the cell theory?

Answers

Answer:

See the answer below

Explanation:

The invention of the microscope paved way for the development of the cell theory because, without it, the cell and all the organelles of the cell would not have been discovered and or studied in great detail. It was through the use of  a microscope that Robert Hooke was able to observe and name the cell and it was through the same microscope that the fine details of the cell were able to be studied by other scientists, culminating in the formulation of the cell theory.

The cell theory states that all living organisms are made up of cells, the cell is the basic unit of all life, and cells can only arise from already existing cells (via cell division). The components of the cell theory, therefore, are:

Living organisms are made up of cells.The cell represents the basic unit of life.Cells can only arise from preexsiting cells.

Explain the mechanism of ventilation in human lungs (you should talk about the diaphragm, abdominal muscles and rib cage and intercostal muscles)

Answers

Answer: When the diaphragm contracts, it moves inferiorly toward the abdominal cavity, creating a larger thoracic cavity and more space for the lungs. Contraction of the external intercostal muscles moves the ribs upward and outward, causing the rib cage to expand, which increases the volume of the thoracic cavity.

The movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.

The ventilation in human lungs or pulmonary ventilation is defined as the process of intake of air during inhalation, and expiration as the release out of air. It is also termed as breathing.

What is the mechanism of pulmonary ventilation?

The lungs are present in the thoracic cavity, with the diaphragm below the lungs separating the thoracic cavity from the abdominal cavity. The rib cage is present outside lungs and prevent them.

Inhalation process in pulmonary ventilation

The inhalation is the process of taking in air. The increase in the volume of lungs results in the increased movement of diaphragm to the abdominal cavity.

The intercostal muscles move upwards and the rib cage move outwards. Thus, the air is inhaled in the system.

Exhalation process in pulmonary ventilation

The exhalation of air is performed antagonist to the inhalation. The relaxation of diaphragm and the movement of rib cage results in the decreased volume of the lungs, and the air is expelled.

Thus, the movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.

why are viruses not regarded as true living cells?​

Answers

Explanation:

Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Viruses are not comprised of cells, they cannot maintain a stable internal environment, they cannot reproduce, and they cannot produce their own energy.

What is environment?

Environment is defined as a compilation of all the factors living and nonliving and the outcomes they have on human life. Due to their ties to the forest, its plants, wildlife, water, and air. The air is filtered and hazardous gases are absorbed by the forest and trees. Plants filter water, lessen the likelihood of flooding, preserve the natural equilibrium, and do many other things.

Viruses are more like robots than actual living things, even though they do replicate and adapt to their surroundings. The viruses are thought to be dead in their natural habitat since they lack any cell-like properties. However, inside the host cell, the viruses employ the host's technological infrastructure to carry out all necessary tasks including reproduction.

Thus, viruses are not comprised of cells, they cannot maintain a stable internal environment, they cannot reproduce, and they cannot produce their own energy.
