Answer:
The classic tool to predict the patterns of heredity is using a <u>Punnett Square</u>.
Explanation:
In genetics, a trait can be considered dominant or recessive. Since the important discoveries of Gregor Mendel, scientists use a <u>capital letter (D) to indicate a trait is dominant, and a lowcase letter (d) to show a trait is recessive. </u>
Assuming that a scientist knows the genotype for the desired trait they want to predict on the offpsring, a Punnett Square is<u> a reliable tool and a graphic representation that permits them to visualize the potential features of the offspring by showing how the alleles may be exhibited and passed on the offspring and will determine the possible combination of genotypes.</u>
<em>How does it work?</em>
For example, as we can observe in the image below, both parents are homozygous for a trait <em>PP=Purple; pp=white</em>. P is dominant and p is recessive (the color purple will be dominant, and the white will be recessive). So, we put one parent's genotype in the top row (PP) and the other parent's genotype in the left column (pp) and combine one of each letters on the squares, <em>i.e</em>. one of each parent's alleles. Then, we can observe in the results that 3 of the offspring will exhibit the purple color (PP, Pp, Pp) and only one will exhibit the white recessive color (pp); or more properly known as a genotypic ratio of 3:1.
If it is always expressed it is dominant, also dominant allele is a possible answer. If it is not expressed unless both alleles are the same, it is recessive.
Protists = eukaryotic organisms tgat are mostly classfies as unicellular/ mostly seperate nuclear division phases of mitosis doesnt occur
for now we know that it is not d (bacteria) or a (too board)
c and b show describe a word called 'cell specialisation'
i think the answer is c since it is said to be mostly unicellular and we know that single cell doesnt have much specilaised cell
idk
They store energy for the body cells with the difference that carbohydrates give the cells short-term energy while lipids give them long-term energy, meaning it takes more time for that energy to be lost
A mold was developing in some of the culture dishes used by Sir Alexander Fleming and was eliminating some of the bacterial population. The hypothesis is that the mold was generating a chemical, which was toxic to the bacteria in the dishes and killed them.
The hypothesis was examined by separating the Penicillium and administering it into the solution of nutrient broth. After the growth of Penicillium it was withdrawn from the broth. The broth was then eventually supplemented to the bacteria and the bacteria died. Thus, it can be concluded that the hypothesis is supported.
