<u>Answer</u>:-
It is option c:
“He build sit underneath a tree”.
Explanation:
The second fire goes out because the man makes a mistake:
He builds the fire under a Pine tree. Although this makes it easier for him to collect sticks to feed the flames, it ultimately proves fatal. Eventually, the snow falls onto the fire itself, extinguishing it and leaving in its place a pile of fresh ❄️ snow.
True, plants undergo cellular respiration because they need ATP.
Plants are known as primary producers in the ecosystem because they are able to directly harness the energy from the sun and convert it into complex energy molecules. This process requires ATP.
On the other hand, plants also undergo cellular respiration which is the process by which ATP is produced because the plant also needs ATP to perform the functions of cells.

Answer:
c. 1:2:1
The results are consistent with incomplete dominance for this trait, with pink flowers being heterozygous.
Explanation:
If flower color were determined by a gene showing incomplete dominance, the possible genotypes and phenotypes are as follows:
- RR- red
- ww - white
- Rw - pink
If pink sweet peas are self-pollinated, then a cross between two heterozygous individuals is done (Rw x Rw).
<u>From this cross the expected ratios are:</u>
- 1/4 RR (red)
- 2/4 Rw (pink)
- 1/4 ww (white)
So the null hypothesis is that the observed results exhibit a 1:2:1 ratio.
<h3><u>Chi square test</u></h3>
<u>The observed frequencies were:</u>
Total 150
<u>The expected frequencies for our null hypothesis are:</u>
- 1/4 x 150 = 37.5 Red
- 2/4 x 150 = 75 Pink
- 1/4 x 150 = 37.5 white
The degrees of freedom (DF) are calculated as number of phenotypes - 1; in this case DF = 3-1 = 2.
If we look at the Chi square table, for 2 DF and a probability of p0.05, the critical value is 5.991
Our X^2 value of 0.5067 is less than the critical value, so we do not reject the null hypothesis. The results are consistent with incomplete dominance for this trait, with pink flowers being heterozygous.
Answer:
D
Explanation:
Just trust me.
it's not A because there's no such thing as favorable traits whenever it comes to incesticide and for B the majority of Beatles and future generations will also die that's only to the ones that died but that can not happen, which means that D is the one that will be the correct answer because if one lives, then the rest of the generations live due to immunity in the generation that started it.
A small flowerless green plant with leaflike stems or lobed leaves, occurring in moist habitats. Liverworts lack true roots and reproduce by means of spores released from capsules.
