When a person is sleeping, the body moves into 5 different stages which is characterized by a Rapid Eye Movement and a Non- Rapid Eye Movement sleep. The body usually spends 90 minutes in each of the stages. First stage is called the Transitional Phase, second stage is called a Non Rem phase, stages 3 and 4 are known as the deep stages of sleep and the 5th stage is the only Rapid Eye Movement.

What levels of protein structure would be affected if all hydrogen bonding interactions were prevented? check all that apply?

fgiga [73]

The proteins exhibit four levels of organization:

1. Primary structure: It refers to a sequence of amino acids join together by the peptide bonds to produce a polypeptide chain.

2. Secondary structure: It is a localized twisting of the polypeptide chain by producing a hydrogen bond. Two types are formed, that is, the alpha helix and beta pleated sheet.

3. Tertiary structure: It refers to the three-dimensional composition of a polypeptide chain. The folding is not regular as it is in secondary composition. It produces ionic bonds, hydrophobic interactions, disulfide bond, and hydrogen bond amongst the polypeptide chains.

4. Quaternary structure: It comprises an amalgamation of two or more polypeptide chains that functions as a single functional unit. The bonds are identical as in tertiary composition.

Thus, the levels of secondary, tertiary, and quaternary protein structure would get affected if all the hydrogen bonding associations were inhibited.

Now that you have had a chance to delve into epigenetics, think about how it applies to the argument between those who say we ar

jeka94

What we eat (our environment) and genetic variables come together in epigenetics.

Describe epigenetics.

A branch of genetics called epigenetics investigates how variations in the environment might affect how genes are expressed.

DNA methylation, histone alterations, and non-coding RNA pathways are examples of epigenetic mechanisms.

In conclusion, epigenetics is the fusion of genetics and environment.

Which choice best describes the relationship between biodiversity and invasive species?

german

Answer:

b. As invasive species increase, it causes biodiversity to decrease

Explanation:

Invasive species refers to those species of organisms that are foreign (non-native) to a particular environment or habitat with the tendency to outgrow and outcompete the native species in that habitat. Due to their fast reproductive and growth rate, they tend to diminish the population of native species by using up the available nutrients.

Biodiversity is the richness of organism species on Earth. When invasive species increase in a particular habitat or ecosystem, they cause the biodiversity in that habitat to decrease because they tend to take charge and dominate, causing harm to every other species. Hence, As INVASIVE SPECIES INCREASE, it causes BIODIVERSITY TO DECREASE
