Which statement best describes Mendelian or complete dominance?



When both the dominant and recessive allele shows.



When the dominant and recessive alleles mix to form a third phenotype.



When the dominant trait or allele completely masks the recessive allele.

Answers

Answer 1

Answer:

When the dominant trait or allele completely masks the recessive allele

Explanation:

Mendelian or complete dominance is a relationship of genes in which one allele of a gene pair that codes for a trait expresses itself over the other allele of the gene pair. The allele of the gene pair that expresses itself over the other is the dominant trait or allele, which completely mask the expression of the other allele called the recessive allele or trait.

In the pea plant experiment conducted by Mendel, complete dominance can be seen. For example, for seed color of pea plant, allele for yellow seed color was dominant over allele for green seed color.

Why do two grams of fat provide a different amount of energy than two grams of carbohydrates? (2-3 sentences)

Answers

Answer:

Fats are the slowest source of energy but the most energy-efficient form of food. Each gram of fat supplies the body with about 9 calories, more than twice that supplied by proteins or carbohydrates. Because fats are such an efficient form of energy, the body stores any excess energy as fat.

Explain how the shape of a river's stream bed can affect the river's speed and its power to cause erosion.

Answers

Explanation: The shape of a river's stream bed affects the speed and eroding power of a river by influencing the amount of friction between the water flowing through the river and the stream bed below. Friction is the force that opposes the motion of one surface as it moves across another surface. In a river, there is friction between the flowing water and the stream bed beneath it. Where a river is deep, less water comes into contact with the stream bed, so there is less friction. The reduced friction means there is less opposition to the water's motion, so the river flows at a greater speed and has more kinetic energy for erosion. On the other hand, where a river is shallow, more water comes into contact with the stream bed, so there is more friction. The increased friction means there is more opposition to the water's motion, so the river flows at a lesser speed and has less kinetic energy for erosion. Also, the roughness of a stream bed covered with boulders and other obstacles causes the water to flow through the river in a turbulent fashion. This could cause the river to move slower in some cases or erode more in other cases.

*mark as Brainliest ty*

Answer:

It changes the amount of friction there is. There is more friction where water is shallow, and less friction where water is not as shallow. The friction has the power to cause erosion as it causes movement of water.

An expiriment was done to determine if the rate at wich a patato cooked depended on the temperature of water in which it was boild. What are the independent and dependent variable??​

Answers

Answer:

The independent variable  is  the  potato   and dependent variable  will  be  the  temperature

Explanation:

When  this  experiment  is  done  it  consider  about  the  boiling  rate  of  the  temperature  which  it  helps  to  cook  the  potato.  in  other  words  when  you  do  this  experiment  you  will  try  different  temperature  levels  on  the  same  type  of  vegetable  which  is  a  potato.  so  the  variable  called  temperature  will  be  dependent  because  its  the  variable  that  we  change.  and  the  variable  called  potato  will  be  the  independent.

Anna applies a force of 84n Nto lift her baby nephew 2.0 m. How much work
does Anna do? Answer


Answers

Answer:

168 J

Explanation:

Work can be calculated using the following formula.

w=f*d

where w is work, f is force, and d is distance.

Anna applied a force of 84 Newtons, and lifted the baby 2.0 meters.

f=84 N

d=2 m

Substitute these variables into the formula.

w=84 N* 2 m

Multiply

w=168 N-m

A N-m is the same as a Joule, or J.

w= 168 Joules

Anna does 168 Joules of work.

Jordan's grandmother uses the juice from squeezed lemons to remove stains from his shirt. He hypothesizes that the juice is the only part of the lemon that is effective at removing the stains, because it’s an acid. Which two steps would help Jordan determine whether his hypothesis is scientifically supported?

Answers

Answer: I would say The hypothesis that the juice of the lemon is the only pat of lemon that is capable of removing stains from the t-shirt is because the lemon juice is acidic in nature.

1.) To test the validity of this hypothesis he should test the acidity of different parts of the lemon including the juice, pulp and skin of lemon.

2.) He should also compare the lemon juice with other juices to know weather other juices are also helpful in removing stains from the t-shirt.

Describe Lamarck’s idea about how organisms evolved. Use the giraffe’s neck as an example.

Answers

Answer

Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.

Lamarck believed that the stretching elongated the giraffe's neck, which became a useful characteristic and was passed onto future generations. This resulted in the length of the giraffe's neck increasing over time. It is now commonly accepted that Lamarck's ideas were wrong.

Answers

Answer:

A. [tex]-tan\theta[/tex]

Explanation:

Given

[tex]sin\theta\ .\ tan\theta\ .\ sec\theta .\ cot(-\theta)[/tex]

Required

Simplify

[tex]sin\theta\ .\ tan\theta\ .\ sec\theta .\ cot(-\theta)[/tex]

Substitute [tex]\frac{1}{cos\theta|}[/tex] for [tex]sec\theta[/tex]

So, the expression becomes

[tex]sin\theta\ .\ tan\theta\ .\ \frac{1}{cos\theta} .\ cot(-\theta)[/tex]

Rearrange the above expression

[tex]sin\theta\ .\ \frac{1}{cos\theta}\. \ tan\theta\ .\ cot(-\theta)[/tex]

[tex]\frac{sin\theta}{cos\theta}\. \ tan\theta\ .\ cot(-\theta)[/tex]

From trigonometry;

[tex]tan\theta = \frac{sin\theta}{cos\theta}[/tex]

So, we have

[tex]tan\theta\ . \ tan\theta\ .\ cot(-\theta)[/tex]

From trigonometry;

[tex]cot(-\theta) = -cot(\theta)[/tex]

So, the above expression becomes

[tex]tan\theta\ . \ tan\theta\ .\ -cot(\theta)[/tex]

[tex]-tan\theta\ . \ tan\theta\ .\ cot(\theta)[/tex]

From trigonometry;

[tex]cot\theta = \frac{1}{tan\theta}[/tex]

So, we have

[tex]-tan\theta\ . \ tan\theta\ .\ \frac{1}{tan\theta}[/tex]

Express as a single fraction

[tex]\frac{-tan\theta\ . \ tan\theta }{tan\theta}[/tex]

[tex]-tan\theta[/tex]

Hence, [tex]sin\theta\ .\ tan\theta\ .\ sec\theta .\ cot(-\theta) = -tan\theta[/tex]

A. A book about planning sexual activities
B. Scientific research on the body
C. The news paper
D. An age restricted site showing nudity

Answers

Answer:

B. Scientific research on the body

Explanation:

B is the most plausible answer because option A and D will not answer your research question about sexual hormones (from a scientific perspective) and option C will have information which will not help you make conclusions since newspaper take their information from other sources and sometimes leave out chunk of data or information to fit it in one page.

Therefore, best option is B to look into scientific research on body where you'll likely encounter research related to blood rushing and sexual hormomes.

why can AIDS be classified as both an infectious disease and an immune system disorder ?
