<span>When pregnant and expecting mother should gain between 15 and 25 pounds of weight, which is considered normal and healthy.

A student decides to set up an experiment to see if detergent affects the growth of seeds. he sets up 10 seed pots. 5 of the see
Black_prince [1.1K]

By placing the pots with detergent in the sun and the pots without detergent in the shade, the student is not comparing the effects that detergent has in the growing rate of the seeds under the same conditions; besides, he does not have a control group. Therefore, he will not be able to determine if the growing rate of the plants were affected by the detergent, the lack of sunlight, or a combination of both factors.

Heart muscle cells would tend to separate without ________
Hitman42 [59]
The answer is intercalated discs. They allow the heart muscle cells to function as one organ due to a phenomenon known as syncytium. This is where uninuclear cells fuse to form an apparent multinucleate cell. This way the heart muscle cells can contract in synch. Intercalated discs appear in the sarcomere's (of the muscle fibres) Z line.

In a population of grasshoppers, the color green (G) is completely dominant over the color brown (g). If 23% of the population i
barxatty [35]
The answer is 49.92%

Let's use the <span>Hardy-Weinberg principle:
p + q = 1
p</span>² + 2pq + q² = 1
<span>
where:
p - the frequency of dominant allele G
q - </span>the frequency of recessive allele g
p² - the frequency of homozygous dominant individuals GG with colour green
2pq - the frequency of heterozygous individuals Gg with colour green
p² - the frequency of homozygous recessive individuals gg with color brown

23% of the population is brown: p² = 23% = 0.23
p = √(p²) = √0.23 = 0.48

p = 0.48
p + q = 1
0.48 + q = 1
q = 1 - 0.48 = 0.52

<span>The percentage of the population that is expected to be heterozygous is 2pq:
2pq = 2 * p * q = 2 * 0.48 * 0.52 = 0.4992 = 49.92%</span>
