In rats, gene B produces black coat color if the genotype is B–, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D–, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. Determine the genotypes of parents of litters with the following phenotype distributions. Part A 4 brown, 4 black, 4 yellow, 4 cream

Answers

Answer:

Bbdd and bbDd

Explanation:

From the illustration:

B_dd - black color

bbD_ - yellow color

B_D_ - brown color

bbdd - cream color

In order to produce litters in the ratio 4 brown, 4 black, 4 yellow, and 4 cream; the genotypes of the parents must be Bbdd and bbDd. The cross between the two parents would be such that:

      Bbdd    x    bbDd

4 BbDd - brown color

4 bbDd - yellow color

4 Bbdd - black color

4 bbdd - cream color

See the attached image for the Punnet's square analysis of the cross.

Why does a gummy bear soaked with water shrink after being soaked with salt water?

Answers

Answer: Because they were placed in a hypertonic solution, there was a natural tendency for water to leave the gummy to create an isotonic solution. The greater amount of salt in the salt water solution would cause more water to leave the gummy. Therefore, the gummy would shrink more in a higher concentration of salt water

Explanation:

The gummy bear shrinks after being soaked with salt water because the gummy bear loses water to the environment.

OSMOSIS:

Osmosis is the process whereby water moves from a region of higher concentration to a region of lower concentration through a semipermeable membrane.

The salt water in this question represents a hypertonic solution that contains high salt conc. but low water concentration.

This means that if the gummy bear is placed in a salt water, water will move from the cells of the gummy bear (low concentration of salt) to its environment (high salt concentration) based on osmotic principle.

Therefore, gummy bear shrinks after being soaked with salt water because the gummy bear loses water to the environment.

1. What did Linnaeus use to classify living things?

Answers

Answer:

Perhaps the single greatest contribution Linnaeus made to science was his method of naming species. This method, called binomial nomenclature, gives each species a unique, two-word Latin name consisting of the genus name and the species name. An example is Homo sapiens, the two-word Latin name for humans.

Explanation:

Can I have brainliest

It is from Google

Binomial nomenclature, which Carolus Linnaeus created, is a system for categorizing living things. Linnaeus was a Swedish botanist and biologist.

Binomial nomenclature is a biological system for naming organisms.

It is quite difficult to identify an organism internationally and keep track of the number of species when it has multiple local names.

Some of the features of binomial nomenclature that Linnaeus used to classify living things are:

Latin names are used because they are universal and consistent.

The process of naming each organism uniquely using the two words "genus" and "species."

The arranging of living things into a hierarchy, with each organism being given a position based on how similar it is to others.

Humans, for instance, are known as Homo sapiens. Its name, Homo, translates to "man" in Latin. The name of the species, sapiens, means "wise".

Therefore, Binomial nomenclature is used by Linnaeus to classify living beings.

If you are looking at an object that measures 0.5 mm and the image you see is 10 mm long. Your friend is looking at an object that is 0.1 mm long using the same magnification. What is the size of image does your friend see?

Answers

Your friend sees it as 2mm. Have a nice day

The size of the image seen by a friend has been 2 mm.

What is magnification?

Magnification can be given as the process of enlarging the image to a degree unlike the physical and the apparent size. The use of magnification glass has been forming the enlargement of the images or objects.

The magnification can be given as:

m = v/u

Where, m = magnification, v = object height, and u = image height

The size of the object (v) = 0.5 mm

The size of the image seen (u) = 10 mm

The magnification (m) of the image seen by a person has been:

m = 0.5 mm / 10 mm

m = 0.05

The image seen by a friend of the object (u) of 0.1 mm with a magnification (m) of 0.05 is:

0.05 = 0.1 mm/ u

u = 0.1 mm/0.05

u = 2 mm

Thus, the size of the image seen by a friend with the magnification same as the person has been 2 mm.

Why must dioecious organisms find mates in order to reproduce?

Answers

Answer:

Most familiar is biparental reproduction (sometimes called dioecious reproduction). ... Dioecious reproduction leaves the greatest genetic variability among offspring (an advantage under changing conditions or in competition or when faced with disease), but the organisms must find mates.

Most of the dioecious organisms find mates  in order to reproduce because they are unisexual in nature and they always need a partner to reproduce.

What are the two types of reproduction ?

The two types of reproduction are sexual and   It is the mating between two partner that happens in the case of sexual reproduction. In the case of asexual it is the single parent giving rise to its younger ones.

In the case of dioecious animals that is the organisms bearing either of males or either of females and in this case it is hard for organisms to give birth to their younger ones individually.

dioecious animals need to find the partners as per the compatibility and the specificity. The individuals with the compatibility and the specific orientations give rise to their younger ones and this process is called as reproduction.
