Hydrophobic effect is the tendency of non polar molecules (hydrophobic) in a solvent that is polar to interact with each other resulting to a hydrophobic interaction. These non polar molecules are called hydrophobes and are made of long chains of carbon that are water hating (do not interact with water). In this case,the hydrophobic interactions are most likely to occur on the core of a water soluble protein.
Answer:
A-Weight
Explanation:
Genes, genders, and parents will be the same in identical twins.
A medical patient is suffering from mysterious fainting spells. A medical team works to get to the bottom of the problem and identify the cause. So the correct option is B.
<h3>What is the scientific method?</h3>
The start of a scientific investigation is observation. This means anything that catches the attention of the scientist. For example, for a cancer biologist, a certain kind of cancer might be an observation that can't be treated with chemotherapy and he would wonder why it is so.
For all the sciences, the core is a problem-solving approach which is called the scientific method. There are five basic steps in the scientific method. These are:
- Observation of a phenomenon
- Questioning the reason or cause for it.
- Hypothesizing or giving a testable explanation
- Making a prediction based on the hypothesis.
- Testing the prediction.
- Using the results to develop new hypotheses or predictions.
Therefore, the correct option is B.

Site-specific recombination systems all of the choices are correct i.e.
A. do not depend on extensive nucleotide sequence homology.
B. depend on enzymes that are often specific for sequences within the host.
C. are features of some viruses.
- An exchange between two specified sequences (target sites), either on the same DNA molecule or on two separate DNA molecules, is known as site-specific recombination.
- DNA sequences may be integrated, excised, or inverted as a result of the exchange.
- A site-specific recombinase that can work by itself or with the aid of additional components or enzymes shapes the DNA target during recombination.
- The recombinase is chemically bonded to the ends of the intermediate DNA after DNA breakage at the recombination site; when this process is reversed, the intermediate DNA is resealed to form the recombinant and the recombinase is released.
- During this recombination process, neither replication nor repair are necessary.

Answer:
b. "C" “B” “A,” “D”
Explanation:
C is prophase because the nuclear envelope starts to disappear and the centrosomes divide
B is metaphase because chromosomes line up to form the equatorial plate
A is anaphase because the sister chromatids are separated
D is telophase because new nuclei form around the separated genetic material
