<u>Answer:</u>

<em>A constant is something whose value cannot be changed and is used for comparison purpose. </em>

<u>Explanation:</u>

The controlled variable is a type of variable whose value is kept constant during the experiment to get the desired or expected result. The difference between constant and a control variable is that the constant can never be changed.

However, the value of control variable can be changed but is kept constant with a purpose in an experiment to get the data. The controlled variable in a battery can be the multi meter that should be used for all the batteries.

Test One: All short fur
Phenotype ratio: 4:0
Test Two: three short fur and one long fur
Phenotype ratio: 3:1
Test Three: all long fur
Phenotype ratio: 4:0
Genotypes for fur length dominant
G: FF, and Ff (These are the genotypes for short fur, short fur is a dominant gene.
P: Short fur is dominant
Genotypes and phenotypes for fur length recessive
G: ff
P: Long fur is recessive
If you have a hamster with short fur, the possible genotypes the hamster could have is FF, and Ff
If you have a hamster with long fur, the possible genotype is ff.

The Hubble constant measures distance in?
PIT_PIT [208]

GIVE ME BRAINLIEST PLS LOL    

The value of the Hubble constant is estimated by measuring the redshift of distant galaxies and then determining the distances to the same galaxies (by some other method than Hubble's law). Uncertainties in the physical assumptions used to determine these distances have caused varying estimates of the Hubble constant.

Which of the following is not a part of the process of translation?a. initiator tRNA binding to the ribosome b. removal of intro
inna [77]

Answer: b. removal of introns from mRNA

The process by which Ribosomes   attached to ER or lying freely in the Cytoplasm  synthesize  proteins from the transcribed mRNA of  the DNA is called Translation.

Explanation:

It is made up of three stages;

1. INITIATION;Options C   mRNA binding to the ribosome

2. ELONGATION ;Option D joining large and small ribosomal subunits

3, TERMINATION;Option E chain termination at a stop codon

However, Introns are non coding  region  of RNA base sequence  transcribed from the DNA, or  sections  of DNA encoding  the RNA. It is  an unwanted part which must be sliced out  before translation. Therefore it is not a relevant  steps of translation, and  hence   Option B is  the wrong answer.

Note the coded part of RNA trancripts is called EXONS. this the part with the needed information.
