A charity group wants to give away insect-resistant corn seeds to farmers in poor countries. One of the main insects that harms corn crops in these countries is the corn rootworm.

To decide which type of corn to give away, the charity group tests 4 types of corn to see which one the corn rootworms like least.

Data from Rootworm Test

Corn Sample
Name Plant Height
(in feet) Attacked by
Rootworm? Ear Length
(in inches) Pounds per
acre
A 7 yes 8 650
B 4 no 4 2400
C 6 yes 5 1260
D 5 yes 7 450


Some of the farmers receiving the seeds want to grow the corn with the biggest ears because they think this corn will produce the most food per acre. Other farmers think that the tallest plants will produce the most food per acre.

Based on the group's research, which type of corn resists the corn rootworm best and therefore produces the most corn per acre?
A.
Sample B
B.
Sample A
C.
Sample C
D.
Sample D

Answers

Answer 1

Answer:

Sample B

Explanation:

The rootworms don't attack it

Answer 2

Answer:

Sample B

Explanation:

When people put time, money, or effort into reaching a goal, such as helping feed people in poor countries, they need scientific evidence to help make decisions. This is because the solution that seems right might not actually be the best one once all the evidence is studied.

While it seemed that the tallest plants or the plants with the largest ears would produce more corn, the scientific evidence showed that this was not true, at least when the corn was attacked by the corn rootworm.

The charity group's research shows that Sample B resists the corn rootworm best and therefore produces the most corn per acre.

In science, the prefix “homo” means same. Homologous structures are structures that are set up the same way. Analyze the picture below of the limbs of a human, dog, bird and whale.
Do these homologous structures support the theory of evolution (the idea that organisms evolve from a common ancestor)? Explain your answer.

Answers

Answer: There are many examples of body structures that are formed in similar ways during embryonic

development and that share similar patterns of bone structure, even though they take on

different forms and perform somewhat different functions. These structures are called

homologous structures. Homo- means same, and -logous means information, so homologous

means “same information”. Homologous structures mean that the animals share a relatively

recent common ancestor.

In a cross between two heterozygous tall and purple flowers (TtPp x TtPp), what would the
ratio be?

Answers

Answer:

9:3:3:1

Explanation:

This question involves two different genes coding for height and flower color respectively. The first gene posseses allele T (dominant) and t (recessive) while the second gene possesses allele P (dominant) and p (recessive).

According to this question, two heterozygous tall and purple flowers are crossed i.e. (TtPp x TtPp). Each parent will produce the following gametes combination:

TtPp - TP, Tp, tP, tp

Using these gametes in a punnet square, the following proportion of offsprings will be produced:

T_P_ (tall, purple) = 9

T_pp (tall, white) = 3

ttP_ (short, purple) = 3

ttpp (short, white) = 1

Hence, the ratio of this cross is 9:3:3:1

Explanation:

The nucleotide sequence on the DNA template that codes for this amino acid sequence b.  TAC AAG GGT AGG GTG.

The DNA template that codes for this amino acid sequence are TAC-methionine, AAG -phenylalanine, GGT -proline, AGG - serine, GTG- histidine.

What is a sequence of amino acids?

The sequence of amino acids causes the polypeptide to fold into an active biological shape. It is encoded in genes.

Hence concluded that protein has the sequence of amino acids: methionine-phenylalanine-proline-serine-histidine, the nucleotide sequence on the DNA template that codes for this amino acid sequence are TAC AAG GGT AGG GTG.

What is the genotypic ratio of a cross between a mother who is heterozygous Type A and a father who is heterozygous Type B?

A. 1 AB : 1 A0:1 Bo : 1oo

B. All AB

C. 2 AA: 2 BB

D. 1 Ao: 2 00:1 Bo​

Answers

Heterozygous means having two different alleles.
The A allele and B allele are dominant. This means that they will be the main allele to express itself. If someone has an A and an o allele, which is recessive, the A allele would express itself over the o allele. A and B are codominant - meaning that if someone had both A and B alleles they’d have type AB blood, as they’d both express.

The mother is heterozygous type A - that means she has one A allele and one o allele
The father is heterozygous type B - meaning he has one B allele and one o allele. I know that it is Bo because if it was BA then he’d have type AB blood because the A and B alleles are codominant.

The genotype ratio is a ratio saying what the chances are of having one type of something (ex blood type, eye color) given the alleles of parents. To find this out make a punnet square with A o on top and B o on the side. Fill it in. I’ve attached a pic of what it will look like.

As you can see 1/4 is AB, 1/4 is Ao, 1/4 is Bo and 1/4 is oo. So the ratio will be letter A: AB:Ao:Bo:oo

Why would injecting more red blood cells into their bodies create an advantage for athletes?

Answers

Answer:

It would be a advantage because red blood cells would carry oxygen and like alot I mean, and the athletes won't run out of breath :3

Explanation:

:3

Answer:

Considering that it is the correct version of the red blood cell (i.e. it is the type they currently have), having more red blood cells can be advantages for athletes. Oxygen plays an important role in exercising. The more oxygen a person has, the harder they can push onward. In this case, as red blood cells carry oxygen and carbon dioxide, more oxygen can be brought to the muscles and other parts of the body, while carbon dioxide can be removed at a much higher and faster rate, allowing for the athletes to continue forward. Just think of it this way, the more oxygen you have, the more you can do.
