mode of transmission of scabies
Answer:
Scabies usually is spread by direct, prolonged, skin-to-skin contact with a person who has scabies. Contact generally must be prolonged; a quick handshake or hug usually will not spread scabies. Scabies is spread easily to sexual partners and household members.
Describe the parts of the building blocks of lipid
Answer:
Glycerol and fatty acids are the basic building blocks of fats (lipids). Fats are the product of the esterification of the trivalent alcohol glycerol with fatty acids of different lengths (between 12 and 20 carbon atoms). Two important representatives of the lipids are triglyceride (90% of fats) and cholesterol.

The essence of meiosis is that a. specialized cell division reduces the chromosome number by half b. gametes are formed that are diploid c. specialized cell division doubles the chromosome number d. gametes are formed that are haploid e. a and d are correct
Answer:
e. a and d are correct
Explanation:
Meiosis produces 4 daughter cells that are haploid. Haploid means they have half of the chromosomes of the parent cell.
The essence of meiosis is that specialized cell division reduces the chromosome number by half and gametes are formed that are haploid.
Therefore option e is the right answer.
What is meiosis?A single cell splits twice during the meiotic process, resulting in four cells with half the original genetic material. These cells are our sex cells—eggs in females and sperm in males—and they are produced by a specific form of germ cell division in sexually reproducing species. Two rounds of division are necessary, and the end product is four cells with just one copy of each chromosome. The goal is to produce gametes, or sperm and eggs, that contain half of the parent cells' genetic makeup. Meiosis is characterized by DNA replication, two rounds of cell division, and the production of four daughter cells, each of which has half as many chromosomes as the parent cell.To learn more about meiosis, refer

all biomolecules are mad up of the elements. A.carbon, hydrogen, nitrogen, oxygen, and sulfur B. carbon, hydrogen, nitrogen, and oxygen C. carbon, hydrogen, and oxygen D. carbon, hydrogen, oxygen, and sulfur
Answer:
Option(A) carbon ,hydrogen,nitrogen,oxygen and sulphur.
Answer:
A.carbon, hydrogen, nitrogen, oxygen, and sulfur
Explanation:
There are five elements that are essential to life. These are Carbon, Hydrogen, Nitrogen, Phosphorous and Sulfur, or CHNOPS for short. We can see that only option A has nitrogen listed. Nitrogen is absorbed by plants through the soil, and by animals through food. It is absolutely essential for many forms of life, especially plants and animals. Many biomolecules contain Nitrogen. Only one choice on this list contains nitrogen and that is option A. Therefore option A is the answer.

Which of the following processes
describes a cell undergoing exocytosis?
A. cell eating
B. diffusion
C. removing water and waste
D. moving molecules along a concentration gradient
Answer:
C. removing water and waste
Explanation:
Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin.
Hope this helps
Answer:
[tex]\boxed {\boxed {\sf C. \ Removing \ water \ and \ waste}}[/tex]
Explanation:
We are asked to find a description for a cell undergoing exocytosis. First, let's define the process.
Exocytosis is a type of active transport, so ATP or energy is required to initiate and complete the process.
This process moves substances from the inside of a cell to the outside. Molecules are packaged into vesicles. The vesicle moves to the cell membrane and attaches. The vesicle fuses with the membrane and the molecules inside the vesicle are released.
Essentially, substances are removed from the cell. This is especially useful because it can rid the cell of any waste or excess water. Therefore, the correct answer is choice C.

From left to right, the correct order of the minerals from the least hard to the hardest is ⇒ Graphite, Talc, Gypsum, Calcite, Fluorite, Apatite, Magnetite, Pyrithe, Feldespat, Quartz.
Theoretical frame:
Hardness is one of the physical properties of minerals and is a significant one when identifying and recognizing them.
Hardness measures the resistance level of a surface to abrasion. In the specific case of minerals, it measures how minerals resist being scratched or penetrated.
The hardness level is determined by an attempt to scratch or produce a mark on an unmarked surface using sharp elements, such as nails, copper coin, glass, or a steal knife. Notice that these elements also vary in their hardness.
There are different methods used to define hardness, and they are not comparable to each other. The Mohs hardness method defines an ordinary qualitative scale that characterizes the mineral according to their resistance to being scratched by a harder element.
According to the Mohs hardness scale, the level in which the given minerals are placed is as follows,
Graphite ⇒ 1 - 2Talc ⇒ 1Gypsum ⇒ 1.5 - 2Calcite ⇒ 3Fluorite ⇒ 4Apatite ⇒ 5 Magnetite ⇒ 5 - 6.5Pyrithe ⇒ 6Feldespat ⇒ 6 - 6.5Quartz ⇒ 7Link to a related question:

What is the effect of these currents on Earth's temperatures?
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
