Answer;

-Parfocal

Parfocal is the word that describes a microscope that remains in focus when the objective lenses are changed.

Explanation;

Parfocal means that when one objective lens is in focus, then the other objectives will also be in focus.

Parfocalling compound microscope objectives is a procedure which allows one to adjust each objective lens so that it will remain in relative focus with the other objective lenses on the microscope when switching from one magnifcation to the next.

Temperature versus Photosynthesis Temperature in Celsius degrees Photosynthetic Rate 0 20 10 40 20 100 25 150 30 200 35 125 40 0
nignag [31]

Answer:

A) Temperature

Explanation:

Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response.

In this question given, the data is portraying the Temperature versus Photosynthetic rate. This means that the experimenter is testing to see the effect of varying temperatures on the photosynthetic rate. Hence, the TEMPERATURE is the independent variable because it is the variable being changed.

A botanist has acquired a group of pea plants. All of the pea plants have yellow pea pods (the recessive form of this trait) exc
Mekhanik [1.2K]

Answer:

Hetezygous

Explanation:

<em>The genotype of the initial green pod plant would be heterozygous.</em>

Let pea pod color be represented by C (c) alleles.

First, let us assume that the genotype of the green pea pod plant is homozygous dominant, CC. This was crossed with homozygous recessive, cc.

           CC   x   cc

      Cc   Cc   Cc   Cc

<u>All the progeny will have Cc genotype with phenotypically green color. </u><u>This is in contrast to the result obtained from the test cross in the illustration, hence the genotype of the initial green pea pod plant cannot be homozygous dominant.</u>

Now, let us assume that the genotype is Heterozygous, Cc.

       Cc   x   cc

 Cc   Cc   cc   cc

<u>50% of the progeny has Cc genotype with phenotypically green color while the remaining 50% has cc genotype with phenotypically yellow color. </u><u>This is consistent with the result from the illustration.</u>

Hence, the genotype of the initial green pea pod plant is heterozygous.

How far will a baseball travel if it's speed is 10 m/s and it comes to a stop after 3s
Inessa05 [86]
We know, v = d / t
Here, v = 10 m/s
t = 3 s

Substitute their values, 
10 = d / 3
d = 10 * 3
d = 30 meters

In short, Your Answer would be 30 m

Hope this helps!
