Which organ is responsible for manufacturing and secreting digestive enzymes and bicarbonate?

babunello [35]

Explanation:

Each part of your digestive system helps to move food and liquid through your GI track, break food and liquid into smaller parts, or both. Once foods are broken into small enough parts, your body can absorb and move the nutrients to where they are needed. Your large intestine absorbs water, and the waste products of digestion become stool.

When is selective breeding okay and when is it not? Provide evidence.

jonny [76]

Answer:

Farmers have been using selective breeding for improving their crop qualities and producing animals with better characteristics.

improved so that mankind can benefit from it.

Selective breeding is not okay on a bigger level where it might eradicate the natural varieties of plants and animals completely. When done on a larger level, the wild-type traits of plants and animals will change and be removed completely. This will lead to lesser genetic diversity.

What makes a tunicate more complicated than a sea sponge?

Umnica [9.8K]

Given what we know, we can confirm that in summary, what makes a tunicate more complicated than a sea sponge is cellular differentiation.

<h3>What is cellular differentiation?</h3>

This is what we call the cells ability to specialize itself into a specific cell type. Some examples of this in humans include:

Heart cells
Digestive cells
Reproductive cells

etc.

Due to this, tunicates have evolved different tissues, organs, and complete cell types, making them much more complicated organisms than sea sponges.

Therefore, we can confirm that due to the multiple tissues, organs, and systems developed through cellular differentiation, tunicates have become more complicated than sea sponges.

Which level of protein structure is a spatial arrangement of the secondary structure? primary structure tertiary structure quate

Tatiana [17]

The answer is primary structure. The protein's primary structure pertains to the amino acids' linear sequence in the chain. Usually, the protein's structure is combined together with a covalent bond that is produced while the process of biosynthesis is present.

An analysis of a cell indicated a high lipid content in the membranes, a high protein content in the vesicles being mobilized an

Anon25 [30]

The option that best illustrates the similarity and difference in the elemental makeup of these molecules is that carbohydrates and lipids both contain carbon, hydrogen, and oxygen atoms, while the proteins contain nitrogen in addition to those three elements. That is option B.

Carbohydrates are macromolecule found is food substances that plays a vital role of energy supply to the body.

It is made up of chemical elements such as carbon,hydrogen and oxygen in the ratio of 1:2:1.

Lipid is another macromolecule found in food which is an energy reserve for the body.

Lipids are made up of elements seen in carbohydrates such as carbon, hydrogen and oxygen but contain many more hydrogen atoms than oxygen atoms.

Proteins are another type of macromolecule found in food which helps in body building and repair of worn out tissues.

Proteins are made up of elements seen in carbohydrates and lipids with the addition of nitrogen atom.

Therefore, carbohydrates and lipids both contain carbon, hydrogen, and oxygen atoms, while the proteins contain nitrogen in addition to those three elements.
