In making an experiment their are two types of variable that should be consider, one is the dependent variable and the other one is the independent variables. I the question that dependent variable would be the result or the effect of the gender of mice and the independent is the ways in determining it. So the variables should be fair if you want your result to have no bias. Thus the answer would be letter B. because it has the same variables but different in gender

I believe the answer to be B, because they are doing the same maze, and getting the same rewards for completing the maze, so it's fair.

Mr. crab loves to fry food. but the grease often splatters everywhere making a big mess. he decides to set up a test in order to determine which dish soap is best at removing grease. he washes 20 greasy dishes with standard dawn dish soap and washes another 20 greasy dishes in his own super awesome amazing dish soap. here dawn dish soap and  super awesome amazing dish soap is the independent variable in this experiment

  • the experiment's independent variable The cause is the independent variable. Its value is unaffected by the other factors in your study.
  • The effect is the dependent variable. Its value fluctuates as the independent variable changes.

A boxer is competing in a match. Which describes the roles of endocrine and neural controls as he boxes?
andrew-mc [135]

Answer:

The correct answer is "The nervous system transmits pain, while the endocrine system elicits the fight or flight response".

Explanation:

One of the roles of the nervous system is to transmit pain to alarm the body that something is going on and that it acts accordingly. The nerve pathway is the one that carries the message of pain from the affected area to the spinal cord and up to the brain. On the other hand, the endocrine system is the one that elicits the fight or flight response. During stressful conditions, the adrenal glands of the endocrine system release epinephrine and norepinephrine that acts during the fight or flight response.

Blue flower is dominant to yellow flower. Tall plant is dominant to short. Cross BbTt * BbTt. What precenetage of the offsprings
shtirl [24]

Answer:

The correct answer would be - 25%.

Explanation:

It is given that the Blue flower is dominant over the yellow flower which means Blue is represented by allele B here and allele b for yellow and Bb is a heterozygous case with a blue phenotypic character. Similarly, the Tall plant is dominant over short and represented by T and t respectively.

BbTt is a heterozygous condition and a cross with itself will produce :

Gametes: BT Bt bT and bt

          BT       Bt       bT       bt

BT     BBTT   BBTt   BbTT   BbTt

Bt      BBTt    BBtt    BbTt   Bbtt

bT     BbTT   BbTt    bbTT   bbTt

bt      BbTt     Bbtt    bbTt     bbtt

Here 4 out of 16 offspring are heterozygous for both traits represented by bold alphabets. Therefore the correct answer is 25%

The Gulf Stream is a surface current in the Atlantic Ocean that flows northward from the Caribbean Sea and the Gulf of Mexico. I
GREYUIT [131]

Answer:

The greatest changes to the path and strength of the Gulf Stream might be caused by an increase in the volume of river water that flows into the Gulf of Mexico (Option B)

Explanation:

The North Atlantic current or Gulf Stream carries warm water from the Gulf of Mexico forward Europe, providing a relative template clime in most of the European occident.

Ocean streams are sensitive to the amount of freshwater available on the surface. An increase in overflow and precipitation over the ocean could slow or revert the north Atlantic current, blocking warm water flow to Europe.

The deposition of freshwater could cause a temporal deceleration or total collapse of the North Atlantic Current, and this interruption might lead to very cold periods in the North Atlantic.
