A student wants to find the benefit of a certain structural trait in mice. What is the first step the student should follow?
A. Design a classroom experiment.
B. Generate a graph of the results of this experiment.
C. Breed me with and without the trait together.
D. Observe the survival rate of mice with the trait in nature.
Help ASAP please
The answer is A. Design a classroom experiment as a first setup starts with an experiment.
Design of experiments, also known as randomized experiments, is characterized by two distinctive features: (i) the deliberate manipulation of treatment, or more generally, the independent variables of interest to the researcher, and (ii). Random assignment of units to treatment and control groups.
What is a mice trait experiment?Studies in mice allow mothers to pass traits to their offspring via bacterial DNA. Summary: A new study in mice has shown that the DNA of bacteria inhabiting the body can pass traits to offspring in a manner similar to that of the parents themselves.
Hence concluded that mice trait is to be performed first.

What are the differences between three types of inertia?
Answer:
Explanation:
Inertia of rest - An object stays where it is placed, and it will stay there until you or something else moves it. ( Dust particles stay at rest until you shake a carpet.)
Inertia of motion - An object will continue at the same speed until a force acts on it. ( Body going forward when a car stops.)
Inertia of direction - An object will stay moving in the same direction unless a force acts on it. ( One's body movement to the side when a car makes a sharp turn.)

The following diagram shows a system of the human body. What is the main function of this system?
Explanation:
B. to break down food so that it can be used by the body
The diagram shows the digestive system of humans system. The main function of this system is to break down food so that it can be used by the body. The correct option is B.
What is the digestive system?The digestive system is the system that starts from the mouth to the intestine of the body. It includes the esophagus, liver, intestines, and small and large intestines, pancreas, etc.
This system is responsible for breaking down food material, and this breaking down release energy. This system provides energy to the body. This system contains enzymes and acids that break the food into small forms and release energy in the bloodstream of body.
Therefore, the correct option is B. to break down food so that it can be used by the body.

a. Gina has a rabbit with the genotype rr. Identify the phenotype of Gina's rabbit.
Answer:
she has a rabbit with alleles rhr not rr
so would be the himalayan as rh is dominant
if it was rr as you say (not what the question reads if I am reading it right) then her rabbit would be white fur only

Both the liver and kidneys are organs of the excretory system. How do the two organs work together to complete a task?
Answer:
When the liver has broken down due to harmful substances, its by-products are exerted into the bile or blood. Bile by-products enter the intestines and leave your body in the form of feces. Blood by-products are filtered out through the kidneys and leave the body in the form of urine.
Explanation:
When the liver is damaged by harmful substances, their by-products move into the bile or blood, where the by-products of bile enter the intestines and leave your body as feces and by-products of the blood. -products are filtered through the Kidneys and leave the body as urine.
What is Excretion?Excretion is defined as the process in which metabolic waste is eliminated from an organism, this is done by the lungs, kidneys and skin in vertebrates.
This is in contrast to secretion, where matter may have specific functions after leaving the cell where excretion is an essential process in all forms of life.
Through excretion organisms control osmotic pressure which is defined as the the balance between inorganic ions and water and maintain acid-base balance.
Thus, when the liver is damaged by harmful substances, their by-products move into the bile or blood.

Q: Which image shows the most likely path of a barrel floating down a meandering river?
Answer:
C
Explanation:
A meandering stream has a single channel that snakes through its valley, so the distance 'as the stream flows' is greater than the distance 'as the crow flies.'
Image C is the most likely path of a barrel floating down a meandering river.
What is the meandering of a river?A meandering stream has a single channel that snakes through its valley, so the distance 'as the stream flows' is greater than the distance 'as the crow flies.' The outer edge of the water moves faster than the inner as it flows around these curves.Meanders form as a result of both deposition and erosion, and they gradually migrate downstream. Because of the decreased friction, the force of the water erodes and undercuts the river bank on the outside of the bend, where the water flow has the most energy.To learn more about : Meanders

A wildfire in a forest causes a population of deer to flee to a nearby field. This field is home to a population of rabbits. Which is an effect
of the deer moving to the field?
Answer:
C
Explanation:
They both eat the same thing which is plants this will either cause one of the species to flee to new land with plants or a fight among them for survival
Answer:
Overabundant deer can spell trouble for people, including frequent car collisions and the spread of zoonotic diseases. But deer can also disrupt wildlife communities -- such as forest songbirds -- by eating away their habitat. In a new study, researchers show that areas in the eastern US with high deer numbers tend to have fewer birds that need forest shrubs.

What happens to the cell’s genetic information during the cell cycle?
Answer:I think During most of a cell's life cycle, DNA, along with proteins, is a mass of loose strands called chromatin (KROH-muh-tin). Before cell divion, DNA is duplicated, or copied. Then, in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes (KROH-muh-sohmz).Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.During interphase, the cell obtains nutrients, and duplicates (copies) its chromatids (genetic material). The genetic material or chromatids are located in the nucleus of the cell and are made of the molecule DNA. hope this helps have a nice night ❤️❤️❤️

Answer:
Yes, I belive in evolution because of how muech the world has changed it's form over they years. To break it down a little more take humans for an example we weren't always like this we didn't have all these citys, buildings, tec, and so on. Back in the days when we still have native tribes and explorers they didn't have a house to sleep in they slept in tents or in carrages but as time evolved so did our minds and our brains thats when cabins started then after that houses then cars, power, and even more, but they had to learn how to do this. They evolved their minds to create they evolved to make it throught bad times they had to evolve along with mother nature her self. we all made it this far thanks to the great mind of evolution adn thats why I believe.

How do owls relate to biotechnology?
Answer:
Owls hunt throughout the night in deserted places such as cemeteries, run-down farms, and other open areas. The diet of many owls consists mainly of rodents and other small animals. Prey is usually eaten whole, but the whole prey is not digested. An owl's digestive tract compresses the undigested portions of the prey, such as fur and bone, into a compact pellet that the owl coughs up and expels through its mouth.Explanation:
Genes are located in the nucleus of a cell. But which structures in a cell are they ON?
