Answer: red and green is the most common color blindness
Explanation:
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.

2. Glucose
3. Water

Explanation:
this is the order for smallest to biggest
Ranked the molecules below from smallest to

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.

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.

Which of the following is NOT a disadvantage to precision agriculture?
lack of inexpensive satellite systems
lack of space for farming
lack of understanding of technology
lack of satellite image variability
Answer:
space for farming I guess
Answer: The correct answer is lack of space for farming
Explanation: This answer has been confirmed correct.
Precision agriculture requires less space through optimization, so it is not a disadvantage. The other items (high cost of satellites, high technology curve, and lack of image variability/definition) are all recognized disadvantages.
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.

What is the process in which all of the nuclear DNA is copied?
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.
