The sugar molecules thus formed contain carbon, hydrogen, and oxygen: Their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins or DNA), used for example to form new cells.

the human is able regulate blood sugar levels within a fairly specific range, even high amounts of carbohydrates are consumed

Stells [14]

Question options:

1. Homeostasis

2. Digestion

3. Embryology

4. Cellular respiration

Answer:

1. Homeostasis

Explanation:

Sugar level in humans is regulated by "Insulin" and "glucagon" hormones that are secreted by the pancreas. Both hormones work in a balanced way to regulate the blood sugar level within a specific range if the sugar levels spike or drop.

Together, insulin and glucagon help maintain a state known as homeostasis. By definition, homeostasis is the maintenance of the internal environment of cell/body with respect to the external environment. Thus, homeostasis maintains a relatively stable state that persists despite changes in the world outside. When blood sugar is too high, the pancreas secretes more insulin which acts to trigger breakdown of sugar thus reducing its level. By contrast, when blood sugar levels drop, the pancreas releases glucagon to allow conversion of macromolecules to simple sugars and raise its level.

Imagine you have been shipwrecked and are floating on a small piece of wood in the middle of the ocean. You are terribly thirsty

Sveta_85 [38]

Given the higher salinity of the ocean water in comparison to your stomach cells, you will lose water from your cells and become dehydrated.

Osmosis is a phenomenon that shows that in the presence of a space in which the solute concentration is higher than its current location, water will travel towards that more concentrated space in an attempt to dilute the concentration.

The urge to drink is what we call being thirsty. This urge has a biological origin. It is the body's way of telling you that your cells need more water, which leads us to often consume any water we have available. This is not always in our best interest.

However, due to osmosis, drinking the seawater would only have a negative effect on your stomach cells. As stated in the question, the cells contain less concentration of solute (in this case salt) than the water. This means that instead of entering the cell, water would leave to dilute the new seawater, thus dehydrating you more and worsening your condition.

A new species of chordate is discovered. It produces a free-swimming larva that has a notochord and a nerve cord. The larva atta

umka21 [38]

Answer:

Urochordata

Explanation:

Chordata is an animal phylum characterized by four features at some point in their lifetime. These four features are:

notochord
pharyngeal slits
dorsal hollow nerve cord
post-anall tail

Chordata is further divided into urochordata, cephalochordata and vertebrates.

Urochordates display all the four features of chordates in their larval form but their adult form has none of them except pharyngeal slits. They also change from their free swimming larval form to sessile adult form which means that they attach to a surface unlike the larval form. They also display filter feeding i.e. their food is filtered via the pharyngeal slits. Since all these characteristics are being displayed by the newly discovered species, it belongs to urochordata group.
