A hypothesis does all of the following EXCEPT A) attempt to answer the question

B) be evaluated through experimentation

C) a be refined after evolution

D) acts as a universal principle

Answers

Answer 1

Answer:

D) acts as a universal principle

It's D because a hypothesis is just an educated guess(sort of) of what you think happens. A universal principle is the exact opposite of that.

Answer 2

Answer: D)
Because a hypothesis is an "Educated Guess" so it obviously cannot be a principal that is used in Science. For Example, I could say my hypothesis on Men and Women is that Women are smarter. This is not necessarily true because I don't have any facts yet. In order to discover the answer, I must A) Attempt to answer and see if this is true, B) Evaluate this by doing experiments, and C) I must change my hypothesis so it is correct. I cannot say this is a "Universal Principle" by stating it.
Hope I helped :-)

Describe how enzymes affect chemical reactions and explain why this makes enzymes important to living thing.

Answers

Enzymes boost the speed of chemical reactions.

They are very important because in absence of that, process of digestion would take place in several months.....

Enzymes speed up reactions such as digestion. Without them, we'd take weeks to digest our food, which means we wouldn't be able to survive.

Round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. What is the probability of having offspring that have wrinkled seeds and yellow seed color for the cross RRYY ´ RrYy?

Answers

The answer is 0 percent.

Let's represent alleles and genotypes:
R - dominant allele for round seeds,
r - recessive allele for wrinkled seeds,
Y - dominant allele for yellow seeds,
y - recessive allele for green seeds.

RR - dominant homozygote with round seeds,
rr - recessive homozygote with wrinkled seeds,
Rr- heterozygote with round seeds,
YY - dominant homozygote with yellow seeds,
yy - recessive homozygote with green seeds,
Yy * heterozygote with yellow seeds.

So, in order to have wrinkled seeds, the offspring's genotype must contain rr, and to have green seeds, the offspring's genotype must contain either YY or Yy.
According to the image, all of the offspring will have round, yellow seeds (RRYY, RRYy, RrYY, RrYy).

If RRYY and RrYy is crossed the probability of the offspring having wrinkled and yellow seed is none (zero).

Further Explanation:

Dominant character is the trait that masks the effect of the other character and is phenotypically shown. Whereas, the characters which is been masked is referred to be as recessive character.

In the given case,

• R- Denotes the dominant round seed character.

• r- Represents wrinkled recessive character.

• Y- Shows the dominant character of yellow colored seeds.

• y- Is used to represent the green color recessive trait.

Mentioned below are the possible homo and hetrozygotes of the trait;

 YY – Dominant homozygote which represents the yellow seeds.

 yy – Recessive homozygote representing green color seed.

 Yy – Dominant hetrozygote that represents yellow seeds.

 RR – Dominant homozygote representing round seeds.

 Rr – Dominant hetrozygote representing round seeds.

 rr – Recessive homozygote representing wrinkled seeds.

In the given instance for the offspring to have wrinkled and yellow seed it should have the genotype of rrYy or rrYY.

If the cross of RRYY and RrYy is done as shown in the punnett square; the required condition is not possible.

In a balanced ecosystem, the number of______ is far greater than the number of________ .first blank: (producers, tertiary consumers, herbivores)
second blank: (consumers, omnivores,secondary consumers)

Answers

Ecological balance always require that there must be more producers than the number of consumer. When the equation for ecological balance will be reverse there will be ecological imbalance which is called the disturbances. This will later on cause the scarcity of resource and extinction of one species.

Answer:

Producers / Consumers

Explanation:

From ody ssey assignment 6 page 8 (if printed) under Balance of Nature.
