Can someone explain the Punnett square ?

Answers

Answer 1

Answer:

so in the punnet square, you hvae the 4 squares inside the big on. on top of the square, you have 2 letters, representing the dominant and the repressed genes. On one side, typically  the left, you have another two letters, again genes. to get the gene types to fill in your squares, you take the first letter of the top set and the first letter of the side set. for this example, we are going to use Bb(top) and BB(side). you would take the B from the top, and you would pu it with the B from the side. in the top left square, you should have BB. next, you go and take that same top B and do it with the second letter of the side, B again. this again gives you BB.  next, you take the second letter of the top, b, and you join it with B. in the top right square, you would write or type in Bb. Even though the b was on top, it is after the B because in this cause, it is not the dominant gene. when you do the second top and side letters together, you again get Bb.

Explanation:

the main points.

in this example, i used B to be the dominant gene and b to be the repressed/ submissive gene. you always put the dominant gene letter before the repressedmake sure you fill the squares in properly. in this one, you should have 3 BB and 1 Bb. this shows that the gene set BB is going to showwhen you fill in the squares, the first top letter and the first side letter fill in the top left square.the first top letter and the second side letter go left bottom.second top letter and first side letter go in right top.second top and second side go in right bottom.always place the dominant gene first in the punnet square.

add me and message me if you need more help. we can also zoom to figure it out.

Answer 2
The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.

A mountain climber climbs to the summit of a 7 km mountain and then returns to his campsite located at the base of the mountain. Explain what happens to the temperature and pressure as he ascends to the summit and returns to his campsite.

Answers

Answer:

Temperature reduces and pressure increases as he ascends to the summit while the reverse of this happens when he returns to his campsite

Explanation:

When a person climbs a summit, the pressure increases but the temperature reduces. but as he returns to his campsite the normal temperature and pressure are regained which means the pressure reduces and the temperature increase.

The temperature and pressure decreases as he ascends the mountain and increases as he descends the mountain.

We know that temperature and pressure decreases with altitude. In fact, the temperature decreases by 6.5°C for every 1000 meters increase in altitude. Hence air pressure decreases with increasing altitude.

Hence, for a mountain climber, the temperature and pressure decreases as he ascends the mountain and increases as he descends the mountain.

What is true about these two brothers that have brown eyes:
One has genotype BB the other Bb.
a. they have same phenotype and genotype
b. they have different genotypes and phenotypes
c. they have same phenotype but different genotypes
d. they have same genotype but different phenotypes

Answers

C definitely c hope this helps

The truth about these two brothers that have brown eyes is they have the same phenotype (Brown) but different genotypes (BB and Bb). So, the correct option is C.

What do you mean by Genotypes?

Genotypes may be defined as a given set of alleles that an individual possesses. They are ultimate combinations of alleles.

In this situation, the allele B is dominant over the allele b, therefore, in both cases, phenotypes remain the same i.e. Brown eyes, but the genotypes differ. This defines how an allele interacts with another allele and changes the genotype.

Therefore, the truth about these two brothers that have brown eyes is they have the same phenotype (Brown) but different genotypes (BB and Bb).

Explanation:

The cell is the basic unit of structure and function of all living beings. A cell can also be defined as a morphological, functional, and reproductive unit of all living beings.

Every living organism is made up of one or more cells. All cells are created from an existing cell. A cell is the smallest unit that has all the characteristics of life. A set of cells of similar or the same appearance, embryonic origin, and function is called tissue.

The science that studies the cell is called cytology. There are organic and inorganic compounds in the cell. Of the inorganic compounds, water and salts are the most common. Organic compounds in the cell contain carbohydrates, fats, and proteins.

Question 4(Multiple Choice Worth 4 points)

Answer:

Explanation:

C. Glucose and oxygen become carbon dioxide and water during photosynthesis.

Law of conservation:

A conservation law is a statement used in physics that says that the amount of something does not change in time.

In terms of Law of conservation of mass:

The "law of conservation of mass" is the conservation law that says that the amount of mass is always conserved, even if it is changed into another form.

During photosynthesis, plants take in carbon dioxide (CO₂) and water (H₂O) from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Therefore, correct options that supports a conservation law is option C.

A population of sixteen emu grew to thirty-nine in one year. After two years, the population had grown to forty-eight. The maximum number of emu that the environment can support is approximately sixty due to limited resources such as food and water.


What is the carrying capacity of the emu population?

sixteen

thirty-nine

forty-eight

sixty

Answers

Answer: D. 60

Explanation:  Answer is correct in Edge!!! TRUST ME!!! I'm Brainly!!!  :)  

The carrying capacity is the maximum number of individuals that an environment can support given its available resources and here that is approximately sixty that is the last option.

What is emu population carrying capacity?

in the case of the emu population, the environment may have limited resources such as food and water, which could limit the population size even if there are no other limiting factors. As the population grows, competition for resources could increase, making it harder for individuals to find enough food and water to survive and reproduce.

This could cause the growth rate to slow down or level off as the population approaches the carrying capacity. Other factors that could limit the emu population size include predation, disease, and habitat destruction. If there are predators that feed on emus, the population size could be limited by the availability of prey. Similarly, if there are diseases that affect emus, the population size could be limited by the spread of the disease.

Hence, approximately sixty is the carrying capacity in this case that is the last option.
