Amino acids with hydrophobic R groups are most often found in the interior of folded proteins. true false
Answer:
True.
Explanation:
Amino acids with nonpolar, hydrophobic R groups combine together inside the protein, thereby making hydrophilic amino acid that is outside to interact with the water molecules that surrond it. The hydrophobic molecules tend to avoid water by coalescing to form an oily or waxy droplet. This then make hydrophobic and amino acids to come together in the interior of proteins, which is far from the aqueous environment.
Explain what a karyotype is and
how it can be used to evaluate
the genetic health of an
individual.
Explanation:
Clinical cytogeneticists analyze human karyotypes to detect gross genetic changes—anomalies involving several megabases or more of DNA. Karyotypes can reveal changes in chromosome number associated with aneuploid conditions, such as trisomy 21 (Down syndrome).
Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause problems with a person's growth, development, and body functions.

describe the following Characteristics of Life display organization growth development requires energy reproduction respond to stimuli and maintains homeostasis
Answer:
These characteristics of Life are very important.
Explanation:
Organization growth, development requires energy, reproduction respond to stimuli and maintains homeostasis are the characteristics of Life. These characteristics are very important for survival and for a good life. In the absence of these characteristics, the organisms will die. Energy is required for the growth and development of an organisms. Equilibrium is maintained in the body of organism by maintaining homeostasis in the body which resist change in the body.
how the animals and plants of a healthy ecosystem are organized and interact.
Answer:
A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). ... Decomposers break down dead plants and animals, returning vital nutrients to the soil. Plants take up these nutrients, along with water, through their roots.
Explanation:
Answers please help!
Answer:
Heterozygous = When the offspring inherits two different alleles
Probability = The mathematical chance that something will happen
Trait = Characteristics of an organism that makes it unique
Dominant = The allele that always shows up and hides the weaker allele
Recessive = The allele that is always masked in the presence of the stronger allele
Heredity = The passing of traits from parent to offspring

What do you mean by human population?"Population is the whole number of inhabitants occupying an area and continually being modified by increases (births and immigrations) and losses (deaths and emigrations)." As of now, the rate of birth and immigration is higher than that of death and emigration, due to which population is increasing rapidly.The current human population estimated to have exceeded 7.9 billion.Hence, the correct option is C. The time required to double the population is going down.

jill made the table below during her research on aquatic zones and living organisms. Based on jills observations, which conclusion can you draw? (ik the answer i just need the explanation)
Answer:
B. There are no producers in the benthic zone that relay on photosynthesis.
Explanation:
There are no producers present in the benthic zone because benthic zone is located in higher depth where there is no sunlight so no photosynthesis occurs there. We know that photosynthesis only occurs in the presence of sunlight, if there is no sunlight then there is no photosynthesis occurs and as a result no producer can survive there so we can conclude that there is no producers present in the benthic zone .

Vegetarians (people who do not eat meat) do not need to
worry about fat intake.
O True
O False
Answer:
false.
Explanation:
As you probably know, fat can be used by the body as an energy source – both the fat you consume as food and the fat that is already stored in your cells, depending on circumstances.
If you eat an assortment of whole plant foods, you don't need to worry about saturated fats. If you get 100% of your fats from coconut milk and fake meats, then I'd definitely incorporate more variety into your diet.
Healthier, unsaturated fats are mainly from plant sources such as fruit, seeds, nuts and vegetables. Sources of monounsaturates are olive oil and rapeseed oil. Sources of polyunsaturates are sunflower, soya, sesame and corn oils.
Nuts and Nut Butters. Nuts are a great source of protein, healthy fats and calories, making them an excellent choice if you're looking to gain weight. ...
Avocado. ...
Quinoa. ...
Tahini. ...
