A farmer wants to know if adding antibiotics to cow feed will fatten them up. He takes two groups of 25 cows each. One group is given an antibiotic pill and the other group is given a placebo (empty pill). Both groups were fed the same food, given the same amount of water, and were provided with the same level of activity. They were weighed at the end of a month. Hypothesis: Independent Variable: Dependent Variable: Control Group: Experimental Group:
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.

If the RNA is UAU what will the amino acid be?
Answer-Tyrosine
The genetic code contains the STOP codons UAG, UAA, and UGA. These codons serve as a marker for the end of the polypeptide chain during translation.Because they do not encode an amino acid, these codons are often known as nonsense or termination codons.
What are the amino acid in the genetic code?Codons are trinucleotide based units of genetic information found in DNA or RNA that either code for a particular amino acid or signal the completion of protein production (stop signals). There are 64 different codons, of which 61 identify amino acids and 3 act as stop signals.
Therefore, If the DNA is GAT what will be the amino acid-Leucine. If the DNA is TAG what will be the amino acid be -Isoleucine. If the RNA is UAU what will the amino acid be-Tyrosine.

Water-Glucose- Starch- pores in Dialysis tubing- IKI.
Living cells need to obtain nutrients from their environment and get rid of waste materials from their surroundings. This exchange of materials between the cell and its surroundings is crucial to its existence. Cells have membranes composed of a phospholipid bilayer embedded with proteins.This cell membrane can distinguish between different substances, slowing or hindering the movement of other substances and allowing others to pass through readily. This property of the cell is known as selective permeability (Ramlingam, 2008).Water is the smallest size among the given substances i.e. about 0.27 nanometers followed by glucose whose size is 1.5 nanometers. The size of starch ranges from 2 to 10 nanometers whereas the size of pores present in the dialysis tube ranges from 0.1 to 10 nanometers.The last IKI has the largest size of 138.5 km² which is an Island located in Japan so we can conclude that the above rank is based on the smallest molecule to the largest one.

By looking at a map, how can you tell where the profile will be the steepest in a topographic map?
Answer:
The contour lines will be closest together.
Explanation:
When contour lines are closer together, the slope is steep. When contour lines are farther apart, the slope is gentle. This is because contour lines indicate altitude. The closer the contour lines, the faster the increase in altitude, and therefore the steeper the slope.

ATP synthase is an enzyme that helps convert ADP into ATP. Highly active ATP synthase in muscle cells directly increases which of the following?
Answer: pretty sure it’s the number of mitochondria in muscle cells
Explanation:
Highly active ATP synthase in muscle cells directly increases the number of mitochondria.
What is ATP synthase?ATP synthase may be defined as a type of enzyme that significantly catalyzes the formation of the energy storage molecule known as adenosine triphosphate (ATP) through the utilization of adenosine diphosphate (ADP).
According to the context of this question, ATP synthase is an enzyme that performs its function by adding one inorganic phosphate to the ADP molecule. This enzyme belongs to the complex V of the electron transport chain that is mainly produced in mitochondria that provides energy for use by cells.
This complete reaction is accomplished in order to synthesize energy which is needed by the body to do metabolic activities.
Therefore, highly active ATP synthase in muscle cells directly increases the number of mitochondria.

Organisms require nitrogen to make which of the following?
Answer:
amino acids
Explanation:
All organisms require nitrogen to make amino acids, which in turn are used to build proteins.
Nitrogen is required by living organisms to synthesize amino acids. These amino acids unite to form polymers which make proteins.
What are Amino acids?Amino acids are the organic compounds which contain both the amino and carboxylic acid functional groups in it. This is reason, these acids are called amphipathic acids. Although hundreds of amino acids still exist in nature, by far the most important acids are the alpha-amino acids, which comprise proteins. There are only 22 alpha amino acids which appear in the genetic code.
In the structure of an amino acid, the R represents a side chain specific to each amino acid. The carbon atom next to the carboxyl group is called the α–carbon atom. Amino acids which contain an amino group bonded directly to the α-carbon are referred to as the α-amino acids.

Answer:
the answer is dna replication
DNA replication is the process in which all of the nuclear DNA is copied.
What is DNA replication?DNA replication is defined as the biological process of making two identical copies of DNA from a single original DNA molecule that occurs in all living organisms, serving as the most essential part of biological inheritance.
In this process, DNA makes multiple copies of itself which is a biological polymerization, which proceeds in the sequence of initiation, elongation and termination. DNA replication is an enzyme-catalyzed reaction where DNA polymerase is the main enzyme in the replication process. DNA replication is a highly enzyme-dependent process.
Thus, DNA replication is the process in which all of the nuclear DNA is copied.

what happens to p-waves and s-waves at a depth of 2,500 km
Answer:
P-waves pass through both mantle and core, but are slowed and refracted at the mantle / core boundary at a depth of 2900 km. S-waves passing from the mantle to the core are absorbed because shear waves cannot be transmitted through liquids. This is evidence that the outer core does not behave like a solid substance.The compression waves or the P waves exert force in the path of propagation whereas, in shear waves, the action of the medium is vertical to the path of propagation of waves.
P waves can move at a faster rate as compared to the S waves.P waves can move both in the fluid as well as the solid media while S waves can move only through the solid media.At a bottom of 2,500 km, the P waves reach both the mantle and core but grow slower at the mantle-core frame.The S waves on another hand get absorbed during travelling through the mantle and core because shear waves cannot travel through the liquid state.Therefore the P wave can travel easily while the S wave will get absorbed.

Explanation:
The water droplets/rain dissolves the fertilizers and make it easier for the plant to suck it.The bacteria present in the roots of the plant takes up the nitrogen and helps the plant to grow.The cow eats the plant and the nitrogen is in the cow's body.After some years the cow dies and its body is eaten up by animals and when it decays, the nitrogen in its body mixes with the earth and thus is taken up by plants and used. The plant gives out air and vapours containing nitrogen through transpiration and other processes which then results in the release and mixing of nitrogen with other gases and thus resulting in rain.Hope you got it... :)
