Answer:

C.Silicon

Explanation:

By far, the most prevalent bulk material for solar cells is crystalline silicon (c-Si), also known as "solar grade silicon". Bulk silicon is separated into multiple categories according to crystallinity and crystal size in the resulting ingot, ribbon or water.

How many times more energy is produced by all three stages of cellular respiration than by glycolysis alone
Jlenok [28]

The all three process of cellular respiration produces 18 times more ATP than glycolysis alone.

As there are 4 ATP produced in glycolysis from one molecule of glucose,2 from Krebs cycle, and rest 34 from electron transport chain.

These three process made total of 38 ATP

Lentic Systems and give examples
Dmitrij [34]

Answer:

Lentic is a class of aquatic ecosystems that are found on land, such as:

   ponds

   rivers

   lakes

   swamps

   streams

Mostly, lentic ecosystems are described as still bodies of freshwater, and they are smaller ecosystems. Some lentic ecosystems contain animals and microorganisms, but they mostly rely on the photosynthesis of algae and underwater plants to produce energy to thrive. One of the requirements of a lentic body of water is that it is exposed to the sun to encourage photosynthesis.

Explanation:

A lentic ecosystem entails a body of standing water, ranging from ditches, seeps, ponds, seasonal pools, basin marshes and lakes. Deeper waters, such as lakes, may have layers of ecosystems, influenced by light. Ponds, due to their having more light penetration, are able to support a diverse range of water plants.

Writing Assignment So, you have learned about how the denaturation of proteins works during lecture, and you have seen examples
ivanzaharov [21]

Solution :

Denaturing may be defined as the process where the protein they lose their shape and their function because there is a change in the pH level or in the temperature. Although the amino acids sequence also known as primary structure, it does not change. But the shape of the protein might change a little bit so much that it can become dysfunctional in which protein is considered to be denatured.

The enzyme, Pepsin, the breakdown protein in our stomach only operates at a very low pH level. At higher pH level, the pepsin's configuration the way the polypeptide chain is being folded up in a 3 dimension begins to change. The pH level of the stomach is maintained at a low level to ensure that pepsin continues for the digest protein and that it does not denature.

There are 4 levels of the protein structure --- they are the primary, the secondary, the tertiary and the quaternary.

The primary protein is a particular sequence of amino acids in each of the polypeptide chain that makes the protein. The final protein structure depends on this sequence.

Secondary structure arise from the interactions between the neighboring or nearby the amino acids as polypeptide starts folding into 3D form.

The tertiary structure is the most important of structural levels in determining.

The quaternary structure also applies to the proteins made from more than one polypeptide chain.

Usually, one allele is called dominant, which means that an organism will always have that trait if the dominant allele is prese
LenKa [72]

Answer:

Explanation:

Since there is no extra information about a specific gene and its inheritance patterns, I am going to base my answers of examples I create.

To begin with, in a pair of alleles, dominant alllele is represented by A (Capital letter) and recessive is done by a (small letter). If an organism has AA (homozygous dominant) it will always show the dominant trait. If it has Aa (heterogyzous dominant) it will also show the dominant trait as one of the alleles is dominant, and finally if it as aa then it will show recessive trait

Which allele in mouse is dominant vs recessive is primarily figured out based on inheritance pattern. If majority of offspring represent a certain trait like black fur coat it is likely that the dominant trait for that gene is black fur coat. Allele that is recessive is masked by the dominant allele so if parents are

Aa * Aa ---> you'll get 4 genotypes AA, Aa, Aa,aa (Here the AA, Aa, Aa will all show the dominant trait because the capital letter A represents dominant allele and it masks the small letter a) whereas, aa will show recessive trait because there is no capital letter or dominant allele to mask the recessive trait.
