i need help finding the chi square value and please explain how u did it, can someone also explain this p value null hypothesis?
Answer:
p^2 + 2pq + q^2 = 1
0.16 + 0.48 + 0.36 = 1 (from the question)
hence, q^2 = 0.36
then, q= square root of 0.36
= 0.6

The rh allele is dominant to pch and r. The rich allele is dominant to r.
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

Explanation:
specific defence systemwhite blood cells can do 3 things = they engulf the microbe, produce antitoxins, produce antibodies to neutralise microbe
> all cells carry a small protein on their surface called antigens
> every cell has a different shaped antigen
> also meaning if lets say a virus mutates its antigen will change shape
so there are 2 types of antibodies that help fight pathogens together
1) lymphocytes : recognise antigen and make a complementary antibody to fit the antigen this will neutralise the pathogen ( basically seals the whole pathogen with antibody meaning it cannot reproduce or produce toxins if bacteria) and ALSO THEY MAKE THE PATHOGEN BIND TOGETHER so that the phagocyte can kill more pathogen at once
2) phagocytes : do not produce antibodies. and they identify the antigen and ingest and destroy the pathogen 70% of white blood cells are phagocytes
fighting diseasesphagocytosis = process of phagocytes destroying pathogenantitoxins producedantibodies producedmacrophages = specialised cell involved in destruction of pathogennon specific defence systemskin

HELP MEEEE PLS Hydroelectric power is produced using the energy of moving water.
Which description tells how this process is accomplished?
A Water flowing upstream is help in a reservoir behind a dam. The water moves up through channels in the dam where it flows past turbines, moving them and creating electricity.
B Water flowing upstream moves through a channel in a dam. The water moves though a generator that produces electricity, and then it moves to a reservoir.
C Water flowing downstream is held up in a reservoir behind a dam. Some water moves down channels through turbines connected to generators which produce electricity.
D Water flowing downstream moves through a reservoir in a dam and past turbines. It then moves through channels and cause a generator to produce electricity.

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.)
Why does ice cream placed in a plastic cooler melt slower than ice cream placed in a metal pot?
A. because metal is a better insulator than plastic
B. because plastic is a better insulator than metal
C. because metal insulates against more heat
D. because plastic conducts more heat
Answer: B
Explanation:
Because Metal is a poor conductor of heat the inside of a plastic container is insulated and the ice cream will stay cooler longer

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

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 ❤️❤️❤️

Blological evolution is the process by which populations of organisms change over time. How could natural selection lead to evolution?
Answer:
Natural selection is the process of nature selecting the fittest animals to survive and/or thrive, making the weaker ones die out. Over time, the animals with the stronger traits will evolve and adapt to its needs.

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's the difference between monosomy and trisomy?
Answer:
Trisomies and monosomies are two types of chromosomal abnormalities. Specifically, a trisomy is when a person has three of a particular chromosome, instead of the usual two. A monosomy is when they just have one chromosome instead of the usual two.
For example: A trisomy is down syndrome
Explanation:
Answer:
trisomy is when a person has three of the particular chromosome rather than two. Monosomy is when someone has one chromosome rather than the usual two.

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:
