Answer:
its a metal chain not a food chain, (steel to be more specific)
Explanation:
Answer:
Genotype: SsBb
Phenotype: Spotted, black
Explanation:
Homozygous, true-breeding brown spotted will have the genotype SSBB while a homozygous, true-breeding solid black rabbit will have the genotype ssbb.
Crossing the two to produce offsprin:
SSbb x ssBB = All SsBb
<em>All the offspring will have SsBb genotype and since S and B are dominant over s and b respectively, the offsprings will appear black and spotted.</em>
<em>See the attached Punnet's square analysis.</em>

<h3><u>Answer;</u></h3>
Whereas segregational petites exhibited Mendelian inheritance, both neutral and suppressive petites followed non-Mendelian patterns that were consistent with the involvement of an extranuclear agent
<h3><u>Explanation</u>;</h3>
- Mutations that yield defective mitochondria are expected to make cells grow much more slowly. These mutants were called petites to describe their small colonies compared to large wild type colonies.
- Petite mutants could not grow when cells had an energy source requiring only metabolic activity of mitochondria - needed sugar as well which is part of glycolytic pathway.
- Segregational petites, segregated in mendelian manner during meiosis. mutations cause defects in genes in cell nucleus encode proteins necessary for mitochondrial function.
- Vegetative petite mutants do not segregate in mendelian manner; two types: neutral and suppressive; carry mutations in mitochondrial genome itself; when two yeast cells are mated, daughter cells inherit mitochondria from both parents.
- Neutral petites lack most of their mitochondrial DNA; when mated with wildtype, the wildtype give their mitochondria so all cells display a normal phenotype.
As a cell gets larger, the internal volume enlarge and consequently the cell membrane has to expand.And so when the volume increases, the amount of surface area that is available to surpass the materials in a cell steadily decreases.So,the surface area to the volume ratio would get smaller if the cell gets bigger. The answer is C.
Answer:
Hydrogen bonds
Explanation:
it should be hydrogen bonds, correct me if I'm wrong
