Well , I think the answer is B

This represents a closed system,and one benifit is that the risk of passing disease between other species is lower than in open system

A bacteria in a hypotonic solution will tend to:
Reptile [31]

Answer:

C) Stay the same

Explanation:

Bacteria have rigid cell walls around their cell membrane. When placed in a hypotonic solution, water enters into the bacterial cell by the process of endosmosis. However, the rigid cell wall resists the increase in the volume of the cytoplasm.

The entry of water into the bacterial cell results in the build-up of turgor pressure inside the cell. Build up enough pressure inside the cell prevents the entry of water into the cell. So, when placed in a hypotonic solution, bacterial cells stay the same due to the presence of rigid cell walls.

3. From problem 2, suppose another boy, Boy C pulls the heavy cabinet with 5 N
kykrilka [37]

Answer and Explanation:

As you can see the boys are pulling in the same direction. This means that we have an example of an unbalanced force, also called the resulting force, since the forces are not canceling out. This whole situation will have a result which is to create an unbalanced net force to move the object or keep it in repayment and that is what we will discover.

First, let's find out what force the two boys exerted. This is very simple, we only need to add the force exerted by the two. 5N + 5N = 10N

The cabinet will be able to move if the force exerted by the two boys (10N) manages to overcome the resistance and the force exerted by the cabinet itself. If they manage to overcome the resistance of the cabinet, the cabinet will move towards the force applied by the boys.

Suppose the human trait for hair type is controlled by a simple dominant and recessive relationship at one locus. Curly hair, C,
Zepler [3.9K]

Answer:

The frequency of the dominant allele, C = 0.2234

and the heterozygous genotype, Cc= 0.1736

Explanation:

Given -  

Curly hair, C, is the dominant allele, and straight hair, c, is the recessive allele

Thus, C is dominant over c

The genotype frequency of curly hair is 52 in 131 students

so, remaining 131-52 = 79 are straight hair students.  

Since straight hair is a recessive allele , the genotypic frequency of "cc" is  

\frac{79}{131}\\0.6030

Frequency of "cc" is represented by q^{2}

Thus frequency of allele "q"  

= \sqrt{0.6030} \\= 0.7765

As per Hardy Weinberg's I equation -  

p+q=1\\p + 0.7765=1\\p = 0.2234

As per Hardy Weinberg's II equation -  

p^{2} +2pq + q^{2} =1\\0.2234^2+2pq+0.6030=1\\2pq= 0.1736

Hence,  

The frequency of the dominant allele, C = 0.2234

and the heterozygous genotype, Cc= 0.1736
