Answer:
B. functional body cavity lined by tissues derived only from endoderm
Explanation:
From the word "Pseudo" means false i.e something that is not true or literally acting in place for a particular real subject.
Coelom on the other-hand is an fluid-filled hollow cavity that act as the skeletal structure for an organism. They act helps serves as cushion effects for the organism.
Ceolomates are organism that have ceolom and the body tissues are derived from the mesodermal layer that lined the body cavity of organism possessing these ceolom.
But in pseudocoelomate they do not have a true ceolom, but there functional body cavity lined by tissues derived only from the endoderm.
The answer is D 49%. I hope this helps.
Darwin was offfered a position as a naturalist on the HMS Beagle, one of the Britsh Royal Navy's survey ship.
<span>F- allele for freckles
f- </span><span>allele without freckles
1) The man is heterozygote and has freckles, its indicating that the allele for freckles is dominant.
A cross between him and a woman who is also </span><span>heterozygote: Ff x Ff
it would result in the following probabilities:
- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
Their son would have a probability of 75% of being born with freckles.
2) The cross resulted in this probabilities:
</span><span><span>- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
So, the chance of being born heterozygote for this gene is 2/4, which is the same as half (50%).
