Answer:
A. Northern tropic, equator, Southern tropic (I think Im not double sure)
B. Because the sun's rays hit the earth's surface at a higher angle at the equator
C. If earth did not tilt and orbited in an upright position around the sun, there would be minor variations in temperatures and precipitation throughout each year as Earth moves slightly closer and farther away from the sun
D. It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.

It is a barrier that prevents materials from moving from one side to the other.
It is a barrier that allows materials to move freely from one side to the other.
It is a barrier with tiny openings that let some, but not all, materials pass through.
It is a barrier that helps materials move from one side to the other.
Answer:
C
Explanation:
Semi means partly
permeable means allowing liquids or gases to pass through it
Semipermeable means allowing some, but not all, liquids or gases to pass through it.
Answer:
c) It is a barrier with tiny openings that let some, but not all, materials pass through.
Explanation:
The prefix "semi-" means "some; partially". "Permeable" means "allow to pass through". Using your knowledge of the purpose of the membrane and the meaning of the word "semi-permeable", you would use context to come to the conclusion that the correct answer is c) It is a barrier with tiny openings that let some, but not all, materials pass through.

which of these is most important for the testing of a new drug to determine?
A. its name
B. its effectiveness
C. its cost
D. its flavor
Answer:
B. its effectiveness
Explanation:
Obviously, a drug (or any medical treatment) should be used only when it will benefit a patient. Benefit takes into account both the drug's ability to produce the desired result (efficacy) and the type and likelihood of adverse effects (safety).
Answer:
When dealing with drugs like Corona virus vaccines i think the effectiveness is most important in that case but when dealing with may be children's syrups the flavour could be most important

Available data:Single diallelic gene codes for hair in Guinea pigsAllele H is dominant and codes for having hairAllele h is recessive and codes for not having hair
For this gene we will assume complete dominance, meaning that the dominant alele completely hides the expression of the recessive allele.
According to this information, we can say that
Genotype Phenotype
HH Hairy pig
Hh Hairy pig
hh Hairless pig
9) Geneviene does not have hair ⇒ Its genotype is hh
10) Fred has hair ⇒ Its genotype is HH or Hh
Possible crosses
11 and 12)
Cross1: If Fred was genotype HH and bred with Genevieve
Parentals) HH x hh
Gametes) H H h h
Punnett square) H H
h Hh Hh
h Hh Hh
F1) 100% of the progeny is expected to have hair and be heter0zyg0us, Hh.
13 and 14)
Cross2: If Fred was genotype Hh and bred with Genevieve
Parentals) Hh x hh
Gametes) H hh h h
Punnett square) H h
h Hh hh
h Hh hh
F1) 50% of the progeny is expected to have hair and be heter0zyg0us, Hh.
50% of the progeny is expected to be hairless and be h0m0zyg0us recessive, hh.
15)
• If the individual with the unknown genotype (Fred) is heter0zyg0us, the phenotypic rate of the descendants is 50% heter0zyg0us -Hh- and 50% h0m0zyg0us recessive -hh-.
• But if the individual with the unknown genotype is h0m0zyg0us dominant, the phenotypic rate of the descendants is 100% heter0zyg0us for the trait, Hh.
16)
The weakness is that even if Fred is heter0zyg0us for the trait, when making the cross it might occur that all individuals in the progeny are born h0m0zyg0us recessive, and there is a risk of missinterpreting the results.
So in that situation, many crosses must be done between fred and genevieve to se sure about Freds genotype.

The letter N in the most common elements for life CHONP indicates (B) Nitrogen.
Elements are the smallest unit that cannot be broken down further. Each element comprises of specific protons, neutrons and electrons. These elements are essential for living organisms as well. The most common elements inside living body are: CHONP, i.e., Carbon, Hydrogen, Oxygen, Nitrogen and Phosphorus.
Nitrogen is the element in the periodic table with an atomic number 7. It is a very essential element in living organisms because it acts as an important constituent of compounds like nucleic acids, amino acids, proteins, etc. In plants it is a part of chlorophyll.

What effect does increase salinity have on the density of water?
1. No affect unless temperature also changes
2. Decreases density
3. Increases density
Answer:
3
Explanation:
For example,The density of seawater depends on the content of salt. It is known that the density of salt is 2.165g/cm3, so the more salt, the greater the density of mixed liquid.
Answer:If you know that dissolution of salt only marginally affects the volume of the solution, how would you expect the density to evolve? It should reasonably increase.
Explanation:
at a given temperature, Should salts be dissolved in the water, and the volume remains reasonably constant, the density
. A solute binds water molecules around itself in a coordination sphere, and should a salt be dissolved, both anion and cation must be solvated; hence an increase in solution density with respect to water.
escribe ONE way that the use of rodenticides affects the kit fox population AND explain how the size of the kit fox population is affected.
One way that the use of rodenticides affects the kit fox population will be a
reduction in the population.
Foxes are secondary or tertiary consumers which feeds on smaller animals
such as rodents in the ecosystem. The use of rodenticides will kill and
reduce the number of rodents available for food.
The reduction in the rodents means lesser source of food for the foxes and a
decrease in the population. The size of the kit fox population is affected
because a larger size being more affected than the ones with a smaller
size/population.
