Bacteria and archaea are the two types of living beings made up of prokaryotic cells.

<h3>What are bacteria and archaea?</h3>

Bacteria and archaea are both prokaryotic and unicellular organisms. This means that they both lack a true nucleus and membrane-bound organelles. The genetic material is present in a long single loop of chromosome, called the nucleoid.

Both bacteria and archaea have a cell wall present outside of the cell membrane. The structural composition of the cell wall is different among them. In bacteria, the cell wall is made up of peptidoglycan (a sugar and protein complex compound) and in archaea, it is made of pure polysaccharides.

Both of these organisms reproduce asexually. They also have flagella for locomotion, pilus for adherence and a capsule outside of the cell wall for protection against conditions like dehydration.

Therefore, bacteria and archaea are living beings made up of prokaryotic cells.

AleksAgata [21]

When the Bicoid protein is expressed in Drosophila, divisions between cells in the embryo are not yet fully developed. This helps to explain that (B) Bicoid protein diffuses throughout the embryo in a concentration gradient.

Bicoid protein acts as a morphogen. This means it shows its effect when the concentration gradient is high. Also abbreviated as Bcd, the protein helps in establishing the anterior and posterior region of the Drosophila. It also represses the translation of caudal mRNA.

Embryo is the initial stage of a microorganism, right after the fertilization. In vertebrates, this stage does not last much longer because the development of organs begins.

Identify the correct order of events that allow nutrients from foods to be used by the body. Group of answer choices digestion,

Lera25 [3.4K]

Answer:

The correct answer is- digestion, absorption, transport, elimination

Explanation:

The process of digestion starts from the mouth with the help of enzymes called salivary amylase present in our saliva. The food then passes through the esophagus to the stomach.

In the stomach, the food is broken down in small fragments by churning movement which mixes digestive enzymes and food to form chyme.

This chyme is passed to the small intestine where several enzymes from the liver and pancreas digest the food in smaller particles and absorb these particles in the blood. Therefore absorption takes place in the small intestine.

Then the solid waste material left behind after absorption is transported from small intestine to the large intestine and from large intestine waste is eliminated out of the body.

Therefore the correct order are: digestion → absorption→ transport→ elimination.

sergey [27]

Answer:

The correct answer is - Barbara.

Explanation:

BAC or basic alcohol concentration is vary in male to female as females are smaller than men so the total blood is less than the men even the weight is same in both.

This the cause that affects the females to get impaired more than the males and easily get intoxicated even though the weight and amount of the alcohol is similar.

Thus, the correct answer is - Barbara.
