Answer:
The correct answer is-
Hypothesis: Antibiotics cause weight gain in cows.
Independent Variable: Antibiotic pill
Dependent Variable: Weight of cow
Control Group: a group of cows gets a placebo pill
Experimental Group: a group of cows gets an antibiotic pill
Explanation:
The Independent variable is the variable that causes the response from the dependent variable or affects the dependent variable in this study the antibiotic pill affects the weight of cows so The independent variable is an antibiotic pill and the dependent variable is the weight of cows.
The control group is the group of subjects that did not get the treatment in a scientific study in the case of this study group of cows that receives the placebo pill is the control group and the experiment group is subjects that receive the treatment which is a group with the antibiotic pill.
RNA and DNA-RNA hybrids are more dense than simply DNA if the density of different nucleic acids is tested using a CsCl gradient.
The primary technique employed in molecular biology is the extraction of DNA, RNA, and protein. Scientists can separate materials according to size, shape, and density by using density gradient centrifugation. Isopycnic centrifugation, a sort of density gradient centrifugation that Meselson and Stahl developed, employed a cesium chloride solution to separate DNA molecules solely on the basis of density. Because DNA has hydrogen bonds between its strands, which makes it less dense than RNA, RNA has a far larger density than DNA. RNA can be obtained at the test tube's bottom using a CsCl density gradient and high centrifugation, whereas DNA can be recovered in the middle layer.

Answer:
The answer is "0.42"
Explanation:
Please find the complete question in the attached file.
Coastal community striped allele intensity 
Landlocked community, strip intensity allele
Its eliminated allele frequency for movement 
community And now in the sturdy vineyard optimum communities, genotype frequency of stripped characteristic (heterozygous device) in coasts
Heritable (striped) allele frecency:
(round up to the closest cent) is therefore the only frequency of coastal people.
The genome of pulling function in host population
Heterozygous feature regularly.
Therefore the inland community rate of recessed (striped), allele rate:
Following migration;
Its percentage of coastal migrants:
Coastal population Non-immigrant percentage of coastal residents:
Stripping coastal community of allele rate after immigration:

[b] The sporangia are knob-like structures.
They are present at the top of the thread-like structures called hyphae.
They are dispersive, i.e. they are scattered by rain, wind or insects.
