Answer:

Skeletal muscle tissue is composed of cells called muscle fibers. When the nervous system signal reaches the neuromuscular junction a chemical message is released by the motor neuron. The chemical message, a neurotransmitter called acetylcholine, binds to receptors on the outside of the muscle fiber.

A particular ant species has four pairs of chromosomes. Identify the genetic possibilities from independent assortment of a game
pantera1 [17]
In this question, the ant has 4 pairs of chromosomes. Each pair of chromosomes will be separated in a gamete, resulting 4 unpaired chromosomes. That is why gamete is called haploid or n.
That means only 1 of the 2 chromosomes that will be carried into a gamete, assuming the gene heterozygote then there would be 2 possibilities. Since each chromosome pairs can produce 2 possibilities for each male or female, their interaction will result as (2x2) 4 possibilities.
Then for 4 chromosomes would be 4^4 possibilities= 256 possibilities of offspring

What is a triacylglycerol ? Discuss the advantages of organisms having triacylglycerol as energy storage molecule?
Sergeeva-Olga [200]

Answer:

Triacylglycerols are acylglycerols with three fatty acid molecules, generally long chain, which can be the same or different; we speak of simple triacylglycerols when there is the same fatty acid in all three glycerol positions, but most are mixed triacylglycerols, with at least two different fatty acids. The properties of triacylglycerols will depend on the type of fatty acids they contain.

Most of the fats and oils of both animal origin (tallow, butter) and vegetable (olive, corn, sunflower, palm, and coconut oils) are formed almost exclusively by triacylglycerols.

Physiologically, triacylglycerols are an important energy reserve. In most eukaryotic cells, triacylglycerols are stored in the cytosol as microscopic fat droplets. In vertebrates there are specialized cells in the storage of fat, adipocytes. In humans, the presence of fatty tissue under the skin, in the abdominal cavity and in the mammary gland stands out.

Science when birds remain airborne and moving without flapping their wings, on what are they gliding?
Citrus2011 [14]

Soaring is a science when birds remain airborne and moving without flapping their wings. They are maintaining thrust and gliding downward but staying aloft

<h3 /><h3>Further explanation</h3>

Soaring birds is where the birds can maintain flight without wing flapping, because they using rising air currents. Many gliding birds are able to lock their extended wings by means of a specialized tendon. Some land birds such as vultures and certain hawks, sustain flight for long periods without flapping their wings.

For example soaring California Condor spreads its primary feathers so that each acts as a small, high-aspect-ratio wing. This reduces turbulence at the wingtips and helping the condor to stay aloft circling slowly in thermals.

Vultures have a low aspect ratio (ratio of length to width of the wing) which generally produce a lot of drag. Vultures overcome the problem of by flying with their primary feathers extended, creating slots between them. Each primary serves as an individual high-aspect-ratio wing. This high-aspect-ratio reducing wingtip turbulence and lowering the stalling speed of the wings. This helps vultures to circle in thermals, maintaining thrust by gliding downward, but staying aloft by sinking at a rate slower than the hot air rising.

Gel analysis of fragments in step 6 shows that even though the undigested DNA and DNA digested with HindIII are both 1000 bp, th
Soloha48 [4]

Answer:

Size of the band varied

Explanation:

In the given question, the options are not provided but based on the information provided in the question, it can be predicted.

When the DNA was digested by the HindIII, then the length of the digest came about 1000 bp and the undigested DNA was also found 1000 bp.

When both the bands were analysed by Gel electrophoresis then the bands do not run to the same distance therefore this shows that the size of both the bands was not equal and their size varied.

Thus, the size of the band varied is correct.
