Answer:
D. pigments; starch.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
A chromoplast can be defined as a heterogeneous organelle or plastids that is typically responsible for pigment synthesis and their storage in a plant. The pigments include red, orange, yellow or chlorophyll.
On the other hand, leucoplast is a colorless plastid i.e plastic lacking photosynthetic pigments that are typically found in storage organs, underground stems, cotelydons, roots, tubers, seeds, or endosperm etc., used for the storage of starch in the absence of sunlight.
Hence, a chromoplast stores pigments while a leucoplast stores starch.
Answer:
There will be null activity for a gene within in the deletion, this means if a genotype has similar phenotype. This suggests that mutant allele and the allele with deletion has the same level of activity.
Explanation:
The limitation of such interpretation is that the phenotypes have the enzymatic activity according to a threshold level. This means that the mutant phenotype is visible till the enzymatic activity is lower than a threshold. If the level rises above the threshold the wild type phenotype is observed.
Answer:
- Genotypes: 50% (Ww) and 50% (ww)
- Phenotypes: 50% will have white wings, and the other 50% will have yellow wings.
- Percent chance: 50% (heterozygous - Ww - yellow) and 50% (homozygous recessive - ww - white)
Explanation:
To answer this question, we make a Punnett square which looks like this:
You cross a heterozygous butterfly (Ww) and a homozygous recessive butterfly (ww), and it gives you:
Ww ww
Ww ww
As you can see from this Punnett square, 2 out of 4 have Ww, which makes it heterozygous and since they have the dominant W trait on them, they result to have white wings. The other 2 have yellow wings, since they have only w on them (recessive trait). Calculate percentages, you get 50% Ww and 50% ww.
<span>There are 4 electron pairs (3 bonding and 1 lone pair) so the angle is 107 degrees. The 4 electron pairs are repelled to give a tetrahedral arrangement but the molecule has a pyrimidal shape due to the lone pair. </span>
