The food chain will be unbalanced if a whole population of robins die. I hope this helps! If this answer is wrong then I would love to recieve some feedback on what I did wrong! Thank you!
If population of robins die, the food chain will be unbalanced and this makes a large impact on the environment.
What is food chain?A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain.
Moreover, it is a linear network of links in a food web starting from producer organisms and ending at an apex predator species, detritivores, or decomposer species. A food chain also shows how organisms are related to each other by the food they eat. Each level of a food chain represents a different trophic level.
Hence, imbalance of food chain results in the extinction of robins from the environment.

Answer:
B. TT
Explanation:
I took the test
Low genetic variation or a lack of genetic diversity increases the risks of extinction. Scientists have observed this in cheetah populations. Captive feline cheetahs at a breeding colony for large cats were exposed to a viral pathogen that killed roughly 50% of the cheetah population. None of the lions in the large cat population developed symptoms or were affected. Scientists know that lions have a more extensive genetic variation, which means they had the gene variations in their immune system necessary to fend off the disease. Describe the evidence that supports how the cheetah population is likely experiencing a lack of genetic diversity. Suggest one way humans can intervene to increase genetic diversity. Predict a potential adaptation that could result from this increase in diversity. (Please be longer than a few sentences)
Answer:
Because the pathogen killed off 50% of the population that means half of the population was susceptible to the disease, meaning that genetic variation is incredibly low because 50% of the species is the same. Humans can fix this by interbreeding cheetahs with different traits, or even breed them with a different species that is compatible for reproduction.
Explanation:
Half of the population was susceptible to the disease since the pathogen killed off 50% of the population, which means that genetic variation is extremely minimal because 50% of the species are the same.
What is genetic diversity?Genetic diversity refers to the total number of genetic traits that make up a species' genetic composition.
It varies greatly depending on the number of species present as well as across species, and it can be linked to a species' longevity.
A group that is genetically homogeneous and exposed to a new pathogen without the gene variant to stop the disease could go extinct.
By performing a skin graft surgery where a portion of skin from a donor cheetah is given to a recipient cheetah, which is easily accepted if it is an inbred population, evidence to support the loss of genetic diversity of the cheetah population can be gained.
By implementing captive breeding programs, encouraging females to breed with various males in order to produce offspring with various traits, protecting the natural habitat, fostering coexistence of the cheetah species with other species and humans.
Also reducing competition for the same food source, we as humans can take action to increase the genetic diversity in the cheetah population.
Thus, these are the evidence that supports how the cheetah population is likely experiencing a lack of genetic diversity.

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.

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: 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

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

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.
