Which should a scientist conclude about data that are inconsistent with the current, scientific understanding of amphibian repro
Nikitich [7]

The Inconsistencies of the data are led to further investigations conclude about data that are inconsistent with the current, scientific understanding of amphibian reproduction

Option B

<h3><u>Explanation:</u></h3>

Class amphibia is one of the classes under the phylum chordata. This class has typical reproductive features. They are the animals that can live in both land and water, and a few are exclusively aquatic. But they essentially need water for the fertilization process. This is because they generally undergo external fertilization and the females lay eggs beside the water body. The males eject the sperms in water which swim through the water into the eggs and fertilize them.

This is the days old theory regarding the amphibia fertilization. But if some new theory comes up someday, that readily don't exclude this theory. The new theory has to pass through several tests and various further investigations where it's seen if the new theory explains most of the amphibia reproduction or not. Then it can be approved along side with the old theory.

A researcher claims that only a portion of the light energy captured by green plants is available for growth and repair. Which o
gtnhenbr [62]

Answer:

This question lacks options, the options are:

A) Light-capturing pigment molecules in green plants absorb red, blue and violet light but reflect green light.

B) The energy of a photon of light is proportional to its frequency and inversely proportional to its wavelength

C) As light energy is converted to chemical energy by metabolic processes, some of the energy is lost as heat

D) Captured energy is stored in the molecular bonds of organic molecules, including simple sugars and starch

The answer is:

As light energy is converted to chemical energy by metabolic processes, some of the energy is lost as heat.

Explanation:

Green plants are capable of synthesizing their own food via a process called photosynthesis. The photosynthetic process uses light energy from the sun to form organic chemicals necessary for the growth and repair of plant tissues.

Plants are able to capture light energy from the sun using their chlorophyll pigment. Out of this captured energy, only a portion of the light energy captured by green plants is available for growth and repair. This is because as light energy is converted to chemical energy (stored in chemical bonds) by metabolic processes, some of the energy is lost as heat.

Action potential in a motor neuron triggers the release of what neurotransmitter?
vodomira [7]

Answer:

Action potential in a motor neuron triggers the release of acetylcholine (ACh) neurotransmitter.

Explanation:

Acetylcholine: It is a neurotransmitter released by motor neurons which bind to the receptors end plates of the motor. When an action potential travel down the motor neuron's axon, neurotransmitter release occurs resulting in an influx of calcium and altered permeability of the synaptic terminal membrane.

The Ca2+ ions allow synaptic vesicles to move and bind with the presynaptic membrane which is present on the neuron and released neurotransmitter from the vesicles into the synaptic cleft. Once it's released ACh diffusion occurs across the synaptic cleft to the motor end plate, and binds with ACh receptor. As the neurotransmitter ACh binds, these ions channel open and sodium ions cross the membrane into the muscle cells.

In this phase reduction of voltage inside and outside the cell occurs, which is known as depolarization. When ACh binds to the motor end plate this depolarization is known as end plate potential. Then depolarization spread with the sarcolemma and creating an action potential. This action potential moves the entire cell and creating a wave of depolarization.

What would you expect to happen if a transfusion recipient had blood type o and a donor had blood type ab?
NNADVOKAT [17]

If a person with blood group type O received blood transfusion from type Ab it will lead to major hemolytic transfusion reaction.  

<h3>What is Blood Transfusion?</h3>

Intravenously putting blood components into a person's circulation is known as a blood transfusion. For a number of medical disorders, transfusions are performed to replenish lost blood components. The blood's components, such as red blood cells, white blood cells, plasma, clotting factors, and platelets, are now frequently used in transfusions instead of the whole blood that was used in earlier times.

Hemoglobin is a component of red blood cells (RBC), which carry oxygen to the body's cells. Although they are not frequently utilized in transfusions, white blood cells are an essential component of the immune system and help the body fight illnesses. The "yellowish" liquid component of blood called plasma serves as a lubricant and is made up of essential nutrients and proteins for the body's overall health.

Two organisms, AABBCCDDEE and aabbccddee, are mated to produce an F1 that is self-fertilized. If the capital letters represent d
Pie

Answer:

1/1024 is the proportion of the F2 genotypes will be recessive for all five loci

Explanation:

When crossing between both parents, all genotypes will give us 100% AaBcCcDdEe. When a self-fertilization is performed this means that it can have a cross for example of two flowers of the same plant with the genotype AaBcCcDdEe In this way, given the law of independent segregation which states that the alleles of two or more different genes are distributed in the gametes independently of each other. The proportion that at this junction the alleles are aa (1/4)  bb (1/4) cc (1/4) dd (1/4) and ee (1/4). The proportions (1/4)* (1/4)*(1/4)*(1/4)*(1/4) are multiplied, obtaining a value of 1/1024
