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.

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

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.

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

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.

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

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.

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:
