What initially causes a nerve impulse? release of enzymes out of the neuron movement of chemicals into the dendrites of the neuron pathogens attacking the dendrites of the neuron red blood cells bathing the neuron

Answers

Answer 1

Answer:

movement of chemicals into the dendrites of the neuron

Explanation:

Nerve impulse occurs when electrical gradient is moved across the plasma membrane of a resting neuron this is done when the neuron receives a chemical signal from another cell or some other type of stimulus. This action potential then travels down the neuron’s axon as an electric current.

Resting potential occurs because of the difference in electrical charge across the plasma membrane of a neuron.

An electrical gradient is maintained by the sodium-potassium pump this is done across the plasma membrane of a neuron when it is not transmitting a nerve impulse this is the resting potential of the neuron.

To confirm about the validity of a company's claim about the efficacy and safety of a new pesticide, a consumer can do: (b) additional studies that will be the reliability check for the claims.

Pesticides are the chemicals used to prevent the damage if crops against harmful small insects or other small organisms. These chemical agents can either kill the pests or slow their growth to a great extent. Pesticides can be of three types: insecticides, fungicides and herbicides.

Reliability check in case of pesticides can be defined as the tests and surveys performed to check for their effectiveness. It is in simple terms a quality check. Reliability check for pesticides are very important because if these pesticides are hazardous, they can cause chronic illness in humans after the consumption of such crops.

monosaccharide profiling of glycoproteins by capillary electrophoresis with contactless conductivity detection

Answers

Monosaccharide profiling of glycoproteins by capillary electrophoresis with contactless conductivity detection is saccharides.

What are saccharides?

Saccharides form one of the major constituents of the biological macromolecules in living organisms. Many biological processes including the protein folding, stability, immune response and receptor activation are regulated by glycosylation.

In this work, we optimized a capillary electrophoresis method with the capacitively coupled contactless conductivity detection for separation of eight monosaccharides commonly found in glycoproteins, namely D-glucose, D-galactose, D-mannose, N-acetyl-D-glucosamine, N-acetyl-D-galactosamine, D-fucose, N-acetylneuraminic acid, and D-xylose. A highly alkaline solution of 50 mM sodium hydroxide, 22.5 mM disodium phosphate, and 0.2 mM CTAB (pH 12.4) was used as background electrolyte in a 10 µm id capillary. To achieve baseline separation of all the analytes, a counter-directional pressure of –270 kPa was applied during the separation. The limits of the detection of our method were below 7 µg/ml (i.e., 1.5 pg or 1 mg/g protein) and the limits of quantification were below 22 µg/ml (i.e., 5 pg or 3 mg/g protein). As a proof of the concept of our methodology, we performed an analysis of monosaccharides released from fetuin glycoprotein by acid hydrolysis. The results show that, when combined with an appropriate pre-concentration technique, developed method can be used as a monosaccharide profiling tool in glyco-proteomics and complement the routinely used LC-MS/MS analysis.

organisms that obtain their energy from producers and other consumers are: group of answer choices chegg

Answers

Organisms that obtain their energy from producers or other consumers are heterotrophs.

What is heterotrophs ?

An organism is referred to as a heterotroph if it consumes other plants or animals for food and energy. Its origins are in the Greek words hetero, which means "other," and trophe, which means "nutrition." Autotrophs and heterotrophs are two general classifications of organisms depending on how they receive energy and nutrients.

In contrast to heterotrophs, which cannot produce their own food and must rely on autotrophs for sustenance, autotrophs are organisms that create their own food through the process of photosynthesis.

Humans and all other mammals, fish, birds, insects, and more basic living forms like bacteria and fungi are examples of heterotrophs.

The cells of the yellow dung fly contain 5 pairs of autosomal chromosomes and one pair of sex chromosomes. Upon completion of Meiosis II, how many chromosomes will each yellow dung fly gamete contain?
A. 5
B. 6
C. 10
D. 12
E. 24

Answers

Answer:

12

Explanation:

6 chromosomes. Each gamete will contain half the number of chromosomes compared to the parent cell after Meiosis II.

Option (B) is correct.

During Meiosis II, the number of chromosomes in each gamete is halved compared to the parent cell. In the case of the yellow dung fly, which has 5 pairs of autosomal chromosomes and one pair of sex chromosomes, the total number of chromosomes is 2*(5+1) = 12.

However, Meiosis II separates sister chromatids, resulting in the formation of four haploid daughter cells (gametes) with half the chromosome number of the parent cell. Therefore, each yellow dung fly gamete will contain 12/2 = 6 chromosomes.

The options given in the question are not consistent with the expected outcome. The correct answer should be B. 6 chromosomes, as the gametes will have half the number of chromosomes as the parent cell after Meiosis II.

The organelle here is lysosome as it collects the trash of the cell. The correct option is B.

What is a lysosome?

A lysosome is a cell organelle that contains digestive enzymes and is membrane-bound.

Lysosomes are involved in a variety of cellular processes. They degrade extraneous or worn-out cell parts. They could be used to eliminate invading viruses and bacteria.

Lysosomes serve as the cell's digestive system, degrading material taken in from outside the cell as well as digesting obsolete components of the cell itself.

The lysosome's interior is acidic and contains numerous enzymes that break down molecules.

It is known as the cell's recycling center, but this does not imply that it only plays a passive role in the cell.

Thus, the correct option is B.
