True or false. Every living organism on Earth has been classified.
Answer:
False
Explanation:
We know more of the moon than we do of our own oceans! There are many, many, organisms on Earth that have not been classified. We have not been able to explore deep in the ocean, extremely cold climates, and some may have even been missed in "our backyard" because Earth is so diverse! According to National Geographic, "Even after centuries of effort, some 86 percent of Earth's species have yet to be fully described, according to new study that predicts our planet is home to 8.7 million species. ... So far, some 1.2 million species are known to science."

If each parent has two sets of genes and chromosomes why do their offspring receive only one set from each parent
Answer:
Because we are diploid humans, and we have 2 chromosomes per set. We get one set from our mother, and one from out father. Each of the sets from our parents are haploid (1 ), so together they are a diploid(2) set. I can go into depth more with meiosis if you need.

How do i write a good hypothesis
Answer:
use "if...then...because"
Explanation:
a good way to write a hypothesis is using "if, then, because" statements because it fully explains your idea. you also need to make sure that your hypothesis is testable and realistic.
example/
Jimothy is testing if jazz music effects bee honey production. he writes this statement:
If jazz is played near a bee hive while producing honey, then the bees will produce more honey because the smooth music will raise their dopamine levels so that they become happier and therefore faster and more productive.
Answer:
I will write some tips in my explanation!
Explanation:
After formulating wh questions, it's time to form a hypothesis or an educated guess, but how do we do this?
First, you must gather the knowledge you already know; ad back it up with something that has happened like a study, article, etc
Example: It is a known fact that distilled water does not contain impurities, in fact, many distilled water companies boast about their water being clean and safe.
This will be the base of your hypothesis, and from here, just add the knowledge of which you know that can make up a well supported hypothesis, which you will then test.
Example:
It is a known fact that distilled water does not contain impurities, in fact, many distilled water companies boast about their water being clean and safe. Because distilled water is free of impurities, we can say that it cannot conduct electricity, but if we add salt to distilled water, the water will then be able to conduct electricity because...

Temperature-sensitive alleles are an example of conditional alleles; at the permissive temperature, the gene has normal function, whereas at the restrictive temperature, the gene has mutant function. You are studying the E2F pathway and you obtain a temperature-sensitive CDK4 mutant. At the permissive temperature, CDK4 functions normally. At the restrictive temperature, CDK4 is non-functional. Would you expect cells to continue growing or stop dividing when at the restrictive temperature? Explain your answer.
When at the restrictive temperature, we can comfortably expect the cell to stop dividing, whilst continuing to grow
The E2F pathway in a cell is responsible for the transition from the G1 stage of the cell cycle to the S stage. The G1 stage is where a cell grows and expands before the duplication of its DNA.
The S stage stands for synthesis. This is the moment in the cellular cycle in which the DNA of the cell is copied in order to prepare for cellular division.
Therefore, if the transition from G1 to S is blocked by temperature restrictions, we can expect the cell to continue growing, but not divide.

Which option distinguishes what a commodities trader would do with the information in the following scenario?
A heat wave is expected to hit the central United States and cause a drought that will kill off many wheat plants.
sell off wheat supplies immediately at their highest price
immediately buy futures contracts at their current prices
cancel all options on future sales of wheat
wait until the heat wave to make wheat purchases
The commodities trader would immediately buy futures contracts at their current prices. The correct option is C.
Thus, a commodities trader would probably predict a decline in wheat supply if they learned about an anticipated heat wave and drought that may affect wheat plants. They would then buy futures contracts at their present levels in response.
By taking this move, the trader is able to protect himself against prospective price rises brought on by the decreased supply of wheat by securing the right to purchase wheat at a certain price in the future. The trader may be able to take advantage of the predicted market conditions before the impact of the heat wave is fully felt by purchasing futures contracts.
Thus, the ideal selection is option C.

narvez 5. Everyone in Dobby's family has a long nose and they brag that they are from a purebred line. Viola has a stubby nose. Draw a punnett square to determine the possible types of noses their children could have had. (Use the genotypes from #2) a. List the possible genotypes and phenotypes for their children. b. What are the chances of a child with a long nose? out of or % c. What are the chances of a child with a stubby nose? out of st or__% d. Would their children be considered purebred like Dobby? Explain:
Assuming a single diallelic gene coding for the trait and expressing complete dominance, the phenotypes, genotypes, and probabilities of getting each of them vary according to the parentals' genotypes. See the options below.
---------------------------------
Since I do not have the genotypes from #2, I will provide different potential scenarios for this question.
I advise you to check on them and see which one matches the genotype from #2.
Let us assume a single diallelic gene is coding for the trait and expresses complete dominance.
SCENARIO 1 ⇒ long nose is the dominant traitLet us say that
L is the dominant allele and codes for long nosel is the recessive allele and codes for stubby noseSince long nose is dominant over stubby nose
LL and Ll ⇒ long nosell ⇒ stubby noseIf Dobby comes from a purebred family and has long nose, his genotype must be LL.
And if Viola has stubbi nose, her genotype must be ll.
Cross 1
Parentals) LL x ll
Gametes) L L l l
Punnett square) L L
l Ll Ll
l Ll Ll
F1) Genotype ⇒ 100% heter0zyg0us Ll
Phenotype ⇒ 100% long-nosed
There is 100% chances for a child to have a long noseThere is 0% chances for a child to have a stubby noseThese children are not purebred**********
SCENARIO 2 ⇒ Stubby nose is the dominant traitLet us say that
S is the dominant allele and codes for stubby noses is the recessive allele and codes for long noseSince stubby nose is dominant over long nose
SS and Ss ⇒ stubby nosess ⇒ long noseIf Dobby comes from a purebred family and has long nose, his genotype must be ss.
And if Viola has stubbi nose, her genotype must be either SS or Ss.
There are two possible crosses.
Cross 1 : Violet is h0m0zyg0us dominant SS
Parentals) SS x ss
Gametes) S S s s
Punnett square) S S
s Ss Ss
s Ss Ss
F1) Genotype ⇒ 100% heter0zyg0us Ss
Phenotype ⇒ 100% stubby-nosed
There is 100% chances for a child to have a stubby noseThere is 0% chances for a child to have a long noseThese children are not purebredCross 2: Violet is heter0zyg0us, Ss
Parentals) Ss x ss
Gametes) S s s s
Punnett square) S s
s Ss ss
s Ss ss
F1) Genotype ⇒ 50% heter0zyg0us Ss and 50% h0m0zyg0us recessive ss

Explanation:
Weathering is the process by which rocks disintegrate into smaller fragments. Rock expands (with heat) and contracts (with cold) in response to temperature changes.
What is Weathering?Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms.
Rock responds to temperature fluctuations by expanding with heat and contracting with cold. This is frequently observed with a weathering process known as Frost wedging, in which water freezes and thaws inside rock fissures. Salt wedging is a different type of weathering in which the salt that is left over after water evaporates can exert pressure on rock fissures.
Thus, Weathering is defined as the process by which rocks disintegrate into smaller fragments.
