When determining CFU/mL, plates with more than 300 colonies should be eliminated from analysis, being designated: Group of answer choices TNTC TSA TVAC TFTC

Answers

Answer 1

Answer:

TNTC

Explanation:

The correct option would be TNTC.

TNTC simply means Too Numerous To Count.  The term is usually reserved for bacterial culture plates with high bacterial loads, usually in the excess of 300 colonies. It is as opposed to TFTC (Too Few To Count) which is the term used when the colony count on a bacterial culture plate is less than 30.

When a bacterial culture plate is too numerous to count, it can either be eliminated from data analysis or the sample diluted to lower the bacterial load.

Besides the interaction between animals and plants, what other factors may be involved in the carbon and oxygen cycles?

Answers

Answer: .co2

Explanation: co2

Answer:

The other factors which are involved in the carbon and oxygen cycles are air, ground, respiration, and photosynthesis.

Which factor contributes to the carbon cycle?

Explanation: Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.

How do plants and animals interact with the carbon cycle differently from one another?

Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood, and leaves decay bringing the carbon into the ground.

Explain your answer.

Answers

Answer: Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity.

Explanation: Hydroelectricity can be defined as the generation of electricity by utilizing the speed of water stream in a reservoir of water. The high speed water current is used to move the water turbine the energy produced in the turbine can be used to generate electricity by the generator.

Would would be the possible gamete combinations?

Answers

Answer:

1/4 WR; 1/4 wr; 1/4 wR; 1/4 Wr

Explanation:

The principle of independent assortment indicates how different genes independently separate from one another when gametic (reproductive) cells develop. When a cell divides by meiosis, homologous chromosomes are randomly distributed to daughter cells, thereby different chromosomes segregate independently of each other. In consequence, each gamete has a unique combination of chromosomes. In this case, the two genes are on different homologous chromosomes, thereby gene variants (alleles) will be randomly distributed to daughter cells during meiosis (anaphase I) and thus the expected proportion of gamete genotypes will be 1/4 WR, 1/4 wr, 1/4 wR, 1/4 Wr.

During the Cardiovascular Function Labster simulation, cardiac output did not increase as much as oxygen consumption rate (which increased 8x), what is the most likely mechanism that could allow increased oxygen delivery by the cardiovascular system

Answers

Answer:

An increase in the rate of oxygen that has been removed from hemoglobin could increase the supply of oxygen by the cardiovascular system.

Explanation:

Hemoglobin is a protein, present in the cardiovascular system, whose main function is to remove oxygen from the lungs and take it to the tissues of the human body. Therefore, the more oxygen is removed from the hemoglobin, the greater the oxygen supply. This applies even in the situation presented in the question above, where cardiac output did not increase in the same way as oxygen consumption. In this case, if oxygen consumption is high, the removal of oxygen from the hemoglobin must be increased to supply this consumption.

Answers

they may be in the same category but they don't have the same biological makeup

The biggest problem in classifying organisms this way is that the way is not well-defined and diverse and if any organism doesn't fall into another kingdom that is added to these kingdoms.

What is classification?

Organisms are classified into groups and classes on the basis of their characters and structure. It helps in identifying and understanding the diversity of living organisms.

The six kingdom classification is based on similar characteristics like cell type, and food. Before this, scientists divide the organism into plants and animals.

Thus, The major issue with this system of classifying creatures is that it is not well-defined and diverse, and if an organism does not fit into one of the existing kingdoms, it is added to those already there.

Answers

Answer:

- Contains myelinated axons: White matter

- Posterior column: White matter

- Located to the periphery of the spinal cord: White matter

- Gracile fasciculus: White matter

- Anterior spinocerebellar tract: White matter

- Medial vestibulospinal tract: White matter

- Marked by low myelination: Gray matter

- Functions to integrate arriving electrical signals: Gray matter

- Contains somas, synapses, and dendrites: Gray matter

- Tectospinal tract: White matter

- Functions to transmit electrical signals rapidly over long distances: White matter

- Lateral horn: Gray matter

- Ventral horn: Gray matter

Explanation:

Both the brain and the spinal cord contain white matter and gray matter. White matter is the tissue responsible for information transmission (i.e., axons); whereas gray matter is mostly involved in information processing (i.e., neuron bodies). White matter is composed of myelinated axons which extend out from the neuron bodies and glial cells, and this tissue connects different areas of the cerebral cortex (i.e., the outer layer of the brain). Moreover, gray matter is composed of neuronal cell bodies or 'soma'  that contain the neuron’s nucleus and unmyelinated axons. Gray matter also has glial cells and capillary blood vessels; whereas white matter also has oligodendrocytes that produce myelin and astrocytes. The color of the white matter is caused by the myelin that surrounds the axons; while the color of the gray matter is due to the capillary blood vessels and neuronal cell bodies. In the cerebrum and cerebellum, white matter is observed in deep areas coated by gray matter; whereas, in the spinal cord, the white matter surrounds the central gray matter. White matter is involved in normal motor and sensory function, this tissue is responsible for learning and coordinating communication between different brain regions. Moreover, grey matter is involved in muscle control and sensory function (e.g., hearing, vision, memory, emotions, speech, decision making, etc).

It is well known that sugars glucose and fructose are the primary fermentable substrates. However, malic acid can also be fermented but to lactic acid rather than ethanol. This is especially important in red wine, why?​

Answers

Answer:

The correct answer is - due to the different bacteria that produce a different enzyme that is involved in the fermentation of malic acid.

Explanation:

In red wine production, malic acid in present in grapes converted to a softer lactic acid. This process is known as malolactic fermentation. It takes place due to the presence of different types of bacterias such as bacteria of the lactic acid family.

These bacterias produce enzymes which is used to convert the malic acid to lactic acid such a process can occur naturally also.
