2. The tests within the API 20E tubes may be performed under? A.aerobic conditions B.anaerobic conditions C.either aerobic or anaerobic conditions

Answers

Answer 1

The tests within the API 20E tubes may be performed under aerobic conditions. The correct option is A.

The API 20E system is a standardized biochemical panel used for the identification of Gram-negative bacteria based on the metabolic characteristics of the organisms.

The tests within the API 20E tubes can be performed under both aerobic and anaerobic conditions.

Aerobic conditions refer to the presence of oxygen, while anaerobic conditions refer to the absence of oxygen.

Some bacteria require oxygen for metabolism, while others can thrive in the absence of oxygen. Therefore, it is important to provide the appropriate conditions for each organism being tested.

The API 20E system includes a range of tests for the identification of various metabolic characteristics, such as sugar fermentation, enzyme activity, and amino acid metabolism.

These tests are designed to be performed under both aerobic and anaerobic conditions, allowing for the identification of a wide range of Gram-negative bacteria.

In summary, the API 20E tubes may be performed under either aerobic or anaerobic conditions, depending on the metabolic requirements of the bacteria being tested. Therefore, the correct answer is A.

Answers

Answer:

                     The answer is     2.1

Answer:

two alleles

Explanation: because This dynamic aspect of mitochondrial transmission from cell to cell is termed mitotic segregation. In Mendelian genetics, a person's nuclear DNA can contain, at most, only two alleles for any particular autosomal gene, one paternally derived (e.g., allele “A”) and the other maternally derived (e.g., allele “B”).

what do the arguments for and against the use of stem cells in medical research share?​

Answers

Answer:   Stem cell research can potentially help treat a range of medical problems. It could lead humanity closer to better treatment and possibly cure a number of diseases:

Parkinson’s Disease

Alzheimer’s Disease

Heart Diseases, Stroke and Diabetes (Type 1)

Birth Defects

Spinal Cord Injuries

Replace or Repair Damaged Organs

Reduced Risk of Transplantation (You could possibly get a copy of your own heart in a heart-transplantation in the future

Stem cells may play a major role in cancer

Better treatment of these diseases could also give significant social benefits for individuals and economic gains for society

Cons

"We should not mess with human life."

"Humans should not be trying to play God"

Some argue that stem cell research in the far future can lead to knowledge on how to clone humans. It is hard to say whether this is true, but we have seen devastating consequences of other research-programs, even with good intentions, such as nuclear research.

Stem cells are cells, which have the ability to transform into many different types of cells. The stems cells have the potential to specialize in any type.

The stem cells are extensively used for research, curing diseases, and especially in developing prosthetics. The stems cells provide new cells for the growth and development of the replaced and damaged cells.

The arguments for and against the use of stem cells are:

Arguments for the use of stem cells in medical research are:

1. The stem cells enhance the growth and development of healthy skin tissue.

2. The cells can be used to enhance the production of collagen.

3. The study of stem cells helps in understanding the causes of disease.

Arguments against the use of stem cells in medical research are:

1. The use of stem cells for research harms human life and dignity.

2. People believe that killing blastocysts or stem cells is equal to taking a human life.

3. However, the transplant of stem cells can be rejected by the patient's body, therefore, can cost the life of the patient.

Therefore, the use of stem cells for research can be fruitful or disadvantageous.

Which of the following answers is NOT correct with regard to convection currents?

A. Convection currents in magma drive plate tectonics.

B.Convection currents in magma are a result of density differences.

C. Convection currents play a role in the movement of Earth’s inner core.

D. Convection currents in magma are caused by temperature differences.

Answers

Answer: C....Convection currents play a role in the movement of Earth’s inner core

The statement which is not correct with regard to convection currents is as follows:

Convection currents play a role in the movement of Earth’s inner core.

Thus, the correct option for this question is C.

What is Convection current?

Convection current may be defined as a procedure that significantly involves the movement of energy from one place to another. It is basically the existence of current in a fluid through convection.

The inner core of the earth has appeared as solid as compared to other parts like the crust and mantle. Most liquid particles are definitely found on the mantle of the earth's surface.

Due to the presence of excessive liquid particles and compounds, the convection current is significantly noticed there.

Apart from this, magma is also a fluid that derives current through convection. It produces in a number of ways like magma driving plate tectonics, density differences in the magma, and temperature differences.

Convection currents are basically the movement of fluid with respect to temperature or density difference within the material.

Therefore, the correct option for this question is C.

Find 2 ways that natural gas forms. List the steps of the two carbon pathways below. Label each location with A for atmosphere, B for the biosphere, G for geosphere, or H for hydrosphere. Use P for the anthroposphere.

Answers

Answer:

Biogenic and thermogenic

Explanation:

Biogenic and thermogenic are the two ways or mechanism that is responsible for formation of natural gas. Biogenic gas is formed with the help of methanogenic organisms that is present in marshes, bogs, landfills, and shallow sediments. Thermogenic gas is formed from organic matter that is buried in the deeper earth where the temperature and pressure are very high.

The organic pathway of the carbon cycle is the pathway in which carbon moves from atmosphere, through producers, herbivores and other organisms in the ecosystems, and converted back to the atmosphere.

In geological pathway, carbon moves from the atmosphere, through the ocean to rocks and the mantle, and then back to the atmosphere.

What are sea stars and brittle stars?

Echinoderms with a star form that belongs to the class Asteroidea are known as starfish or sea stars. These terms are frequently used incorrectly to refer to ophiuroids, which are properly called brittle stars or basket stars in common usage. Due to their membership in the class Asteroidea, starfish are also referred to as asteroids.

The benthic (bottom-feeding) fauna of the maritime environment includes brittle stars. They belong to the Phylum Echinodermata, which includes marine organisms with radial symmetry, five components, and frequent spines. They are commonly referred to as echinoderms.

Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.
