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
Explanation:
self explantory
please give 5 star
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.

Which of the following best describes the cytoplasm in the cell?
a watery substance where cell processes take place
a hard substance that digests food molecules
a watery substance that keeps molecules from leaving the cell
a hard substance that keeps the cell rigid
Answer: A watery substance where cell processes take place.
Explanation: Process of elimination. The 2nd and last answer choices are both immediately wrong because cytoplasm is not a hard/solid substance. And the third answer choice is wrong because the cell membrane’s job is to prevent organelles from leaving the cell, not the cytoplasm. Therefore the answer is A, a watery substance where cell processes take place.
It is a jelly-like liquid that surrounds everything inside the cell.
In the 2016 movie, The Thinning, starring Logan Paul and Peyton List, a group of
teenagers must past a standardized test or be executed. The politicians who developed
this legislation did it because society was suffering from mass population and
legislatures wanted to thin' it out. Predict which is likely to occur as a result. Select all
that apply.
A. The population of children will Demonstrate more variety of intelligence
B. The population of children will demonstrate less variety in types of intellect
C. Intellect may be lost in areas other than academics
D. This will select for more intelligent children
Answer:
B. The population of children will demonstrate less variety in types of intellect
C. Intellect may be lost in areas other than academics
Explanation:
"thinning out" a population will most definitely result in less genetic variety! Children that aren't good at taking standardized tests (but smart at other areas of intellect) will be "executed". My last answer of the day! Hope this helps :)
What is an example of a physical weathering?
A: a metal tool left outside beginning to rust
B: microscopic organisms producing compounds that break down rock
C: a rock wearing down due to acid rain
D: bits being blown off a rock by heavy winds
Answer:
D) Bits being blown off a rock by heavy winds
Explanation:
All the other answer choices are examples of chemical weathering.
Rusting is chemical weathering.
Compounds that break down rocks is chemical weathering.
Acid rain is chemical weathering.
Wind breaking rocks, however, is physical weathering.

How does the genetic code show a shared history among all organisms?
Answer:
All living organisms store genetic information using the same molecules — DNA and RNA. Written in the genetic code of these molecules is compelling evidence of the shared ancestry of all living things. ... Some mammalian genes have also been adopted by viruses and later passed onto other mammalian hosts.
Explanation:
A codon for certain amino acid is the same in every organism.
does respiration increase or decrease atmospheric carbon?
Answer:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

Explanation:
photosynthesis uses this form of energy to drive the process
Answer:
i think its the energy of light
Explanation:
Answer:
Light energy
Explanation:
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

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:

Answer:

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

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

In the Osmosis Gizmo, the cell is placed in a very small chamber. Suppose a cell is placed in a large container of water with a very low solute concentration. What do you think would happen
Answer:
If a cell is placed in a large container of water with a very low solute concentration the solution will be hypotonic in nature. The water will enter inside the cell through semi-permeable membrane of cell. The cell will swell.
