If a plant cell is placed in a solution and the cell shrivels up, what type of solution was it placed in? How do you know?
vladimir1956 [14]

Answer: The solution was hypertonic

Explanation: The reason for this is the fact that the cell shriveled up. The shriveling was caused by water moving out of the cell. This movement is likely caused by a disbalance in solutes between the cell and the surrounding, with the surrounding containing a higher concentration of solutes. Diffusion tries to balance this by moving water out of the cell, thus increasing the concentration inside and reducing the concentration outside.

Which of the following is a basic type of vaccine?
Katyanochek1 [597]

The basic type of vaccines are:

nucleic acid vaccines

subunit vaccine

live, attenuated vaccine

An easy, secure, and reliable method of preventing hazardous infections before you are exposed to them is vaccination. It boosts your immune system and builds up your body's natural defenses against particular illnesses.

Your immune system is trained by vaccinations to produce antibodies, exactly as it does when it is exposed to a disease. However, because vaccinations only include dead or weakened versions of bacteria or viruses, they do not really cause the disease or increase your chance of developing its symptoms.

In order to create immunity, vaccines act in conjunction with your body's natural defenses. Your immune system reacts when you receive a vaccination.

Six fingered offspring are formed from normal fingered parents . why?
Alex777 [14]
<span>Polydactyly in its most common form, is an autosomal dominant mutation. Let's represent the mutation as P and the normal state as +. Thus, if both parents are heterozygous (P+), both would have the mutation (and thus have six fingered). They have 3/4 chances of having a child with the extra digit, 1/4 normal. </span>
