2. Carbohydrate

3. Lipids

4. Carbohydrate

5. Lipids

6. Lipids

7. Carbohydrate

Explanation:

Lipids and carbohydrates are two of the four major biological molecules (the other two being proteins and nucleic acids). They (lipids and carbohydrates) are both long chains composed of elements: carbon (C), hydrogen (H) and oxygen (O).

Lipids called triglycerides are majorly made up of building block fatty acids (long hydrocarbon chains with carboxylic acid) and glycerol ( an hydrocarbon made up of three hydroxyll groups).

Carbohydrates, on the other hand, are made up of long chains of carbon, hydrogen and oxygen with aldehyde or ketone functional group. They are composed of monosaccharide building blocks (also called simple sugars) with general formula CH20(n).

Based on the structural composition of lipids and carbohydrates, structures 1,3,5 and 6 are lipids while 2, 4 and 7 are carbohydrates.

Which type of gene therapy results in alteration of the DNA of a gamete or a fertilized ovum?

larisa86 [58]

Answer:

The correct option is: e. Germline gene therapy

Explanation:

The germline gene therapy, GGT is the modification of the germ cells. In this therapy, a functional gene is introduced into the genomes of the gametes. Such a modification of the germ cell results in all the cells of the organisms to get modified. This change can therefore be passed on to the next generations. Many countries such as Canada, Germany and Switzerland, have prohibited the use of the germline gene therapy on humans.

Which is a characteristic of all vertebrates?

Bond [772]

The presence of vertebral column or notochord at any stage of life in any organism is the characteristic of vertebrate.

Explanation:

An animal is vertebrate if it fulfils the following criteria:

Presence of vertebral column or notochord.

Presence of endoskeleton or backbone.

The spinal cord runs above the vertebral column.

Humans embryo has notochord which becomes a vertebral column.

The alimentary canals end in the anus.

Mouth is present ta the anterior side of the vertebrate.

Have legs, fins or wings for movement.

Presence of a nervous system and sensory organs.

Presence of skin, lungs or gills.

Presence of a circulatory system.

Vertebrates include fish, amphibians, reptiles, birds and mammals.

Carnivorous plants have enzymes that are able to break down the proteins of the insects and small animals that they ingest. The

Ivahew [28]

Answer:

Convergent Evolution

Explanation:

Convergent evolution is the development of similar traits, across many lineages by plants and animals who originally do not have these traits but developed them because of the biome that they find themselves. Carnivorous plants are examples of living things that have undergone carnivorous evolution.

Plants lacking in Nitrogen have undergone carnivorous evolution for up to seven lineages. Sundews for instance have developed flypaper traps, a carnivorous property that helps them trap insects that they eventually digest.

Explain the difference between fire resistance and flame spread. describe the hazards firefighters should be aware of during the

Kaylis [27]

Fire resistance is where the amount of time that material has withstood a standard fire exposure whereas flame spread is the speed at which a flame spread along the surface of a specific material and is considered as the difference between fire resistance and flame spread.

Fire resistance is the resistance to fire that is for a particular specified time and is under circumstances of standard heat intensity. It will not structurally fail or else allow the transition of heat and also not permit the side away from the fire so as to become hotter than a temperature that is specified well.

Flame spread is described as the surface burning characteristics enhanced by building materials. It is the most tested property of the fire performance of a material.

Firefighters should be aware of the growth and spread of a fire as they face respiratory hazards in emergency situations which include oxygen deficiency, temperature elevation, smoke as well as toxic atmospheres. This can also affect both the physical and mental effects of the firefighter and would be worse if proper respirator precautions are not followed.

This indicates that firefighters are regularly exposed to certain concentrations of hazardous materials that include carcinogenic products such as carbon monoxide, benzene, sulphur dioxide, hydrogen cyanide, aldehydes as well as particulates.
