Answer:
Cellular respiration occurs in both plant and animal cells.
Explanation:
Cellular respiration occurs in both plant and animal cells, and is an essential process that organisms need to survive.
Cellular respiration is the main way that organisms create energy from the food that they eat.
It occurs in both plant and animal cells because both plants and animals need a way to convert their food into energy forms, such as ATP.
So, the correct answer is that cellular respiration occurs in both plant and animal cells.
Answer:
Both parents are heterozygous
Explanation:
Assuming the allele for colour in the sheep is represented by S.
A white sheep will have a genotype of SS or Ss assuming S is dominant over s and a black sheep will have a genotype of ss.
Over the couse of several years, a cross betweem two white sheep (SS or Ss?) produced three white and one black offspring. For them to have produced one black offspring (ss), it thus means that the two white sheep are heterozygous:
Ss x Ss = SS (white), Ss (white), Ss (white) and ss (black).
<em>The best explanation is that both parental sheep are heterozygous for the trait.</em>
This hypothesis is incorrect. A good hypothesis must have the word if or then. This hypothesis contains neither of these words.
Answer:
25% or 1/4
Explanation:
The gene for colour in Heliodors is controlled by two contrasting alleles that codes for Red (R) and Yellow (Y) colours. However, these two alleles exhibit incomplete dominance, which is a phenomenon whereby a combination of both alleles gives rise to a third intermediate phenotype that is a blending of the other two parental phenotypes. In this case, both colours gives rise to a heterozygous Orange coloration (RY) in Heliodors.
However, if two orange Heliodors (RY) are crossed, four possible offsprings will be produced with the genotypes: RR, RY, RY, YY. This shows a phenotypic ratio of 1 red: 2orange: 1yellow. Hence, the probability of having a child with red coloration is 1 out of 4 possible offsprings i.e. 1/4.
Expressing this in percentage, we have 1/4 × 100 = 25%.
