Testosterone and oxytocin
Answer:
Initial age of ghost shrimp and water temperature
Explanation:
In an experiment, there are several variables (alterable factors) that determine the outcome of the experiment. A CONTROLLED variable or CONSTANT is a variable that is kept constant or unchanged throughout the experiment. The constant is not changed because it can affect the other variables (outcome) of the experiment.
For this experiment conducted by Mary Beth on the effect of size of the tank on the size of the shrimp after 6months, the constants are INITIAL AGE OF GHOST SHRIMP and WATER TEMPERATURE. This is so because the ghost shrimps of the same initial age must be used to start the experiment, so as to be able to measure the actual effect on the growth. Also, the water in the respective tanks must be the same Temperature so that one experimental group will not be favored over another.
B. The Geosphere is also known as the Lithosphere which is disturbed during this process along with the hydrosphere which pertains to the oceans.
Answer:
Explanation:
A female mouse has white fur; a male mouse has brown fur. The two mice have a litter of seven pups, five of the pups have brown fur, two pups had white fur.
The female mouse fur which is white is inherited in the recessive condition i e it is recessive to the brown fur which is that of the male and the female is purebred meaning she has this gene in the homozygous form. The male that has brown fur seeing that the mating produces both brown and white, the male has inherited this gene as a hybrid (combination of the two alleles: one allele for brown and one for white). This has given us a little idea of what genetics is all about.
