What are the TWO processes during decomposition?
Answer:
Decomposition occurs through two primary chemical processes: autolysis and putrefaction. They often occur in tandem, but one may predominate in certain conditions. Autolysis (or “self-digestion”) is the destruction of cells through the action of their own enzymes.

The region of Earth’s magnetic field shaped by the solar wind is called what?
The region of Earth's magnetic field shaped by the solar wind is called the magnetosphere.
Answer:
magnetosphere
Explanation:
A magnetosphere is that area of space, around a planet, that is controlled by the planet's magnetic field. The shape of the Earth's magnetosphere is the direct result of being blasted by solar wind. The solar wind compresses its sunward side to a distance of only 6 to 10 times the radius of the Earth
The solar wind drags out the night-side magnetosphere to possibly 1000 times Earth's radius; its exact length is not known. This extension of the magnetosphere is known as the Magnetotail
Which statement best describes an example of selective breeding?
A. Scientists use lab techniques to combine pieces of DNA from different sources
B. Gardeners choose which plants they let reproduce based on the plant's traits
C. Farmers produce organisms using genes from more than one species
D. Doctors insert a correct version of a gene into cells to treat a disease
B. Gardeners choose which plants they let reproduce based on the plant's traits is the best example of selective breeding.
What is Selective breeding ?Selective breeding is the process of breeding plants or animals for specific desirable traits. In this process, individuals with the desired traits are chosen and bred together to create offspring that are more likely to inherit those traits. Over time, this can lead to significant changes in the characteristics of a population.
Gardeners often use selective breeding to develop plants with desirable characteristics such as larger fruits, disease resistance, or better flavor. By selecting plants with these traits and breeding them together, they can create new varieties of plants that are better suited for specific purposes.
In contrast, the other options provided involve genetic engineering techniques that involve the direct manipulation of genes or DNA.
Scientists use lab techniques to combine pieces of DNA from different sources in genetic engineering, farmers produce organisms using genes from more than one species through genetic modification, and doctors insert a correct version of a gene into cells to treat a disease through gene therapy. These techniques do not involve the selective breeding of organisms.

What happened to the red blood cells after the sugar was added to the solution?
The red blood cells released water through osmosis. The release of water helped the blood cells take in more sugar for energy
The red blood cells absorbed water through osmosis. The absorption of water helped the blood cells take in more sugar for energy.
The red blood cells released water through osmosis. The release of water helped the blood cells keep a similar concentration of solutes as the outside solution.
The red blood cells absorbed water through osmosis. The absorption of water helped the blood cells keep a similar concentration of solutes as the outside solution
С
D
lol
Answer: C. The red blood cells released water through osmosis. The release of water helped the blood cells keep a similar concentration of solutes as the outside solution.
Explanation:
Osmosis is a process whereby water molecules move from an area where they are in higher concentration than a solute to an area where they are in lower concentration. They do this by moving through a selectively-permeable membrane.
With sugar added to the solution, the water in the red blood cells will have a higher concentration of water in the cells than the solution so water molecules will move from the cell - through the cell membrane - to the solution. They will keep doing so till the concentration of solutes are more or less similar in both the cells and the solution.

Answer: false
Explanation:
Archaea and bacteria both are prokaryotes and reproduce through binary fission, which results in offspring that are genetically identical to parents.
Answer:
I believe the answer is false.
Explanation:
Prokaryotes (Archaea and Bacteria) reproduce asexually through binary fission, in which the parent organism divides in two to produce two genetically identical daughter organisms.

Answer: Proteins
Explanation:
The process where ribosomes use the mRNA to make proteins is called translation.
Ribosome receive direction's from hereditary material to make certain Protein
Ribosome is a Centre for the synthesis of proteins and they get their orders for protein synthesis from the nucleus.Messenger Ribonucleic Acid(mRNA) carries the genetic information to Ribosome where the information is translated to a functional protein, the information is translated using genetic code which are set of triplets codes that represent an amino acid. These amino acids are the building block of protein.
Therefore, Ribosome receive direction's from hereditary material to make certain Protein

4. List and briefly explain the categorical elements of food security. 8 marks
5. Dan consumed a plate of food that contained 345g of carbohydrate, 80 g of protein and 45g of fat. He also drank a glass of drink that contained 12g of alcohol. Calculate the total caloric content of the food and drink. 6 marks (show calculations). PLEASE HELP ME OUT ITS URGENT!!
Answer:
Food refers to any nutritious substance whereas diet refers to the food eaten by organisms daily.
Explanation:
1. Food refers to any nutritious substance that an organisms eat in order to survive and maintain growth whereas diet refers to the sum of food that is consumed by an organism.
2. Malnutrition refers to a condition that occurs from eating a diet which does not supply a healthy amount of nutrients to our body whereas hunger refers to a feeling of discomfort that is caused by lack of food.
3. No, it is not possible to be over-nourished and under-nourished at the same time because a person can attain one condition at a time whether he can be over-nourished or under-nourished.
4. The three elements of food security are availability, access and consumption of food. Availability of food means having sufficient quantities of nutritive food available to a person, access means having sufficient resources to have access to the food and consumption means having taking sufficient amount of nutrients and the ability to absorb and use nutrients in the body.
5. 2,110 calories are taken by consuming 345g of carbohydrate, 80 g of protein, 45g of fat and 12g of alcohol.
In starches the glucose units are joined together by
Answer: glycosidic bonds
The glucose units in starches are joined together by α-1,4 glycosidic bonds.
Starch is made up of two types of polysaccharides: amylose and amylopectin. Amylose is a straight linear chain of glucose molecules linked by α-l,4 glycosidic linkages. Starches have a lengthy, chain-like structure because of the linear arrangement of their -1,4 glycosidic linkages.
Amylopectin is a branched chain of α-d-glucose molecules linked by α-1,6 glycosidic linkage. These bonds are located at the places where the starch molecule branches, and they contribute to the branching structure of starches. Starches are more water soluble than other forms of carbohydrates, such as cellulose, due to their branching structure.
Therefore, In starches, α-1,4 glycosidic linkage bind the glucose units together.
