What is natural selection and how does it drive the evolution of a virus?

Answers

Viruses undergo evolution and natural selection, just like cell-based life, and most of them evolve rapidly. When two viruses infect a cell at the same time, they may swap genetic material to make new, mixed viruses with unique properties. For example, flu strains can arise this way.

A red blood cell leaving the left ventricle of the heart would take which pathway to reach the facial artery?

Answers

Answer:

Red blood cell arrives from the inferior vena cava into right atrium before it passes through the tricuspid valve into right ventricle. It then passes through the pulmonary valve into pulmonary artery before travelling through the lungs and back into the heart, this time the left atrium via the pulmonary vein.

Explanation:

hope this helps

The pathway of a red blood cell that leaves the left ventricle of the heart to reach the facial artery would be: Arch of Aorta > Brachiocephalic Trunk > Right Common Carotid Artery > Right External Carotid Artery > Right Facial Artery

The arch of the aorta can be considered as the peak of the ascending aorta.

The brachiocephalic trunk refers to the second branch to arise from the aorta.

The right common carotid artery arises as a branch of the brachiocephalic trunk of the aortic arch.

The facial artery is a branch of the external carotid artery that supplies blood to the muscles and skin of the face.

In conclusion, the pathway of a red blood cell that leaves the left ventricle of the heart to reach the facial artery would be: Arch of Aorta > Brachiocephalic Trunk > Right Common Carotid Artery > Right External Carotid Artery > Right Facial Artery.

Explanation:

Why is the action of phagocytes considered a nonspecific response?
It does not occur at any specific temperature.
It is not involved with the production of any specific type of lymphocyte.
It does not respond to any specific type of hormone.
It is not a response to a specific type of pathogen.
I haven't seen any answers here that are correct so I'm sharing this information :)

Answers

Answer:

The answer is "Option D".

Explanation:

The action of phagocytes is deemed a quasi answer because it reacts with any particularity on any harmful substance. It is a mechanism where a cell uses its cell membranes to collect any molecules. Macrophages provide the first layer of defense of our system, a non-specific defense mechanism. Your immune response must handle multiple forms of foreign particles, germs, viruses, or harmful proteins. This failure to respond renders the overall response quicker than that of the specific response.

Answer:

It is D. It is not a response to a specific type of pathogen.

In an experimental test of the effects of vitamin B12 on problem-solving performance, _____ is the independent variable and _____ is the dependent variable.

Answers

Answer:

Vitamin C is the independent variable and problem solving performance is the dependent variable.

Explanation:

The independent variable is the variable that can be manipulated or changed to measure its effect. Vitamin C dosage can be changed for difference individuals to see the effect on their problem solving performance.

Dependent variable is the variable on which the effect of independent variable is measure i.e the effect of vitamins C with different dosage will be known or measured base on problem solving performance of an individual.

Therefore ability to solve problems by individual after the intake of vitamin C means its depends on Vitamin C intake.

what level of biological organization is illustrated by the image? click the correct box​

Answers

Answer: Ecosystem

Explanation: This image shows multiple species interacting with their environment: human and rabbit within waterfall and tree.

The level of biological organization that is illustrated by the image is called Ecosystem.

An ecosystem is defined as a self supportiung unit that is made up of a living part (biotic factors) like plants and animals; and non-living part (abiotic factors) like water, soil, air.

In an ecosystem, the biotic community includes population of:

Food producers: That is the autotrophs like the green plants which are seen in the attached diagram.

Food consumers : That is the heterotrophs such as animals and human beings.

The non-living part of an ecosystem is its abiotic component. this consist of:

Abiotic resources: These are what organisms need to stay alive. they include a source of energy (sunlight as seen in the diagram) and inorganic nutrients ( carbon dioxide, water).

Answers

Answer:

The correct answer is -

1. blueprints.

2. cells use DNA as their design plans

Explanation:

Blueprint is a representative drawing of an engineering plan that helps in understanding how and where the desired to construct on the house. It helps in communicating what work should be done in the house. It helps in visualizing how the end product should be.

In cells, the design plan is DNA that encodes all the information in a specific nitrogenous base sequence in order to produce specific functions and produce all the proteins

Immune responses can be either innate (nonspecific) or adaptive (specific). Suppose a person comes into contact with bacteria that cause a disease that the person has experienced previously. The production of antibodies to fight off the infection is considered an _____ response, while the development of a fever to inhibit bacterial growth is considered an _____ response. (the possible answers to the blanks are "Adaptive" and "Innate")

Answers

Answer:

adaptive; innate

Explanation:

The adaptive immune system refers to a specific type of immunity which is found only in vertebrates. Adaptive immunity is defined by the presence of specialized immune cells (i.e., lymphocytes such as T and B cells). The B cells produce molecules known as antibodies which destroy specific pathogenic microorganisms (e.g., bacteria, viruses) and thus prevent diseases in the future. On the other hand, the innate immune system is the first (and evolutionary more ancient) defense line against pathogenic infections or tissue injury. Innate immunity includes, among others, physical barriers, anatomical barriers, phagocytic enzymes (i.e., lysozymes), phagocytic cells (i.e., macrophages), inflammation, etc. Inflammation is defined as an innate immune response composed of complex biological processes that protect the body by eliminating harmful microorganisms and intracellular danger signals, thereby regulating signaling pathways of many diseases.
