¿Cual de las siguientes especies se reproduce por fecundación interna ?

Alexxandr [17]

Which of the following species reproduces by internal fertilization?

a) cats

(b) Toads

(c) The fish

(d) alternative b and c

Answer:

(a) Los gatos

Explanation:

Only cats are capable of internal fertilization from the given choices above.

Internal fertilization is the fusion of gametes within an organism. This process occurs during sexual reproduction within the female.

Toads and fishes exhibit external fertilization.
External fertilization occurs where the male sperm externally fertilizes the eggs of the female.
This usually takes place in a moist or wet place especially water bodies. The liquid medium will transport the sperm to the egg.

In cats, the female specie takes in reproductive cells from the male during coitus and it fertilizes the her eggs to produce a zygote.

Between species DNA show

djyliett [7]

<h2>Answer and Explanation</h2>

DNA is called deoxyribonucleic acid. DNA is different in all plants and animals but according to the chemical structure, it is the same as double helix strand that is separated from each other. In a person body, all the DNA are the same but they are different if the cells, tissues, and organs are different. There are some mammals have slightly similar DNA that is humans have 99.6% same DNA as the chimpanzees.

In hamsters, we can examine the genes for coat color and eye color which are linked:B = brown coat, b = white coat, G = green ey

Inessa [10]

Answer:

10.2 cM

Explanation:

Given,

pure breeding parent 1 : BBgg = brown coat and pink eyes

pure breeding parent 2 : bbGG = white coat and green eyes

BBGG X bbgg = F1 = BbGg ( All are brown with green eyes )

When F1 progeny is test crossed with white coat and pink eyes hamster:

BbGg X BbGg = F2 =

brown, pink eyes = 99 = parental

white, green eyes = 103 = parental

brown, green eyes = 12 = recombinant

white, pink eyes = 11 = recombinant

Recombination frequency =

(total number of recombinants / total progeny ) * 100

= [( 11 + 12 ) / ( 99 + 103 + 12 + 11 )] * 100 = (23/225)*100 = 0.102 * 100 = 10.2 %

1 % recombination frequency = 1 cM distance between genes

Hence, the distance between B and G gene is 10.2 cM

A selectively permeable membrane separates two solutions. Water is able to pass through this membrane; however, sucrose (a disac

NNADVOKAT [17]

Answer:

a. Nothing happens because the two solutions are isotonic to one another.

Explanation:

Two solutions of the same molarity are separated from each other by a membrane that allows water molecules but not the glucose or sucrose to move across it. Movement of water across the selectively permeable membrane occurs only when two solutions have different concentrations of solutes. In that case, water moves from a hypotonic solution towards a hypertonic solution. Since both sucrose and glucose solutions have the same tonicity, there would not be any change in the solution.
