Answers

Molecules composed of a small oligosaccharide covalently linked to a phospholipid are called glycolipids.

What are glycolipids?Glycolipids are lipids containing a glycosidic (covalent) link connecting them to a carbohydrate. Their job is to keep the cell membrane stable and make it easier for cells to recognize one another, which is essential for the immune response and for the connections that allow cells to join together to form tissues.Glycolipids are crucial parts of biological membranes that serve a wide range of purposes. They might function as receptors, be necessary for cell aggregation and dissociation, be in charge of particular cellular interaction, and be involved in signal transduction. As a result, the glycosphingolipid is hydrolyzed to produce sugar, fatty acids, and sphingosine (or dihydrospingosine).

A specialized protein in saliva breaks up starch molecules in food into smaller chains of simple sugars. In this reaction, which molecule is the enzyme, which is the substrate, and which is the product?.

Answers

A specialized protein in saliva breaks up starch molecules in food into smaller chains of simple sugars. In this reaction, specialized protein is the enzyme, starch molecules are the substrate and the product is the smaller chains of simple sugars.

In the field of science, we can describe enzymes are a kind of proteins that lower the activation energy of a reaction, hence speeding up a reaction. In the reaction above, specialized proteins that help in breaking down starch molecules are the enzyme.

Each enzyme has an active site into which only a specific substrate can fit and get catalyzed. In the scenario above, starch molecules are the substrates as they are the ones being catalyzed.

The products are the resulting substances that are produced after catalysis. In the case above, as smaller chains of simple sugars are the ending results, hence they are the products.

Due to the ozone layer's increasing absorption of UV radiation, the temperature in the stratosphere typically rises as height does.

Define ozone layer.

The stratosphere, the second layer of the Earth's atmosphere, has layers, one of which being the ozone layer. Our globe is covered in a layer of shielding gases known as the stratosphere.

Because it is stratified, or layered, the stratosphere gets its name. The stratosphere warms up as elevation rises. Because the ozone gases in the upper layers absorb strong UV energy from the sun, the stratosphere gets warmer as it gets higher.

Life on Earth benefits from the ozone layer's protective role.

Meiotic division(s) which reduce(s) the chromosome number is Meiosis I. As a reductional division, meiosis I decreases the amount of chromosomes that each daughter cell inherits.

What is Meiosis?

During meiosis, the number of chromosomes is divided in half.. The number of chromosomes in each daughter cell will be one-half that of the parent cell. Because gametes (sperm, eggs) have half as many chromosomes as diploid (2N) individuals, meiosis is a necessary aspect of the sexual process.

Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Gene dosage is modified is a major contributor to this phenomenon.

In the field of genetics, we can define gene dosage as the quantitative measure or copies of a particular gene that is present in an organism. Abnormalities in the gene dosage at a particular location can cause severe damage to the resulting phenotype.

Gene dosage can lead to chromosome duplications if the copy number or gene product is more and it can cause deletions if the copy number or gene product is less. Such complications will result in abnormal phenotypes or inviable gametes. For example, in Down's syndrome, the person has a modification of the 21st chromosome as there is one extra 21st chromosome present. This leads to a variety of diseases and defects in the person.
