Answer:
A sporangium (plural: sporangia) is the capsule structure belonging to many plants and fungi, in which the reproductive spores are produced and stored. ... The majority of sporangia produce haploid spores through meiosis, although some are able to produce spores through mitosis.
Found this on google, hope it helps, have a great day/night and stay safe!

Let us assign the dominant allele (that of brown hair) letter R
while
We assign the recessive
allele (that of white hair) letter r
We then note down the
Hardy-Weinburg equation p2 + 2pq + q2 = 1
Brown fur population (p2
+ 2pq) = 64% = 0.64
White fur population (q2) = 36% = 0.36
Then we also remember that the frequencies of both allele
add up to 1 (p + q = 1);
Therefore q = ü.36
= 0.6
P = 1 – q = 1 – 0.6 = 0.4
The heterozygous population will be 2*0.6*0.4 = 0.48 = 48%
Homozygous domain population will therefore be (64% - 48%) =
16%
Answer:
Neural crest cell movements are inhibited.
Explanation:
Neural crest cells may be defined as the temporary group of cells that are unique for the chordata group. These cells arise from the embryonic ectoderm and give rise to future melanocytes.
Antibodies to fibronectin association is helpful to study the signalling factors. If these anitodies to fibronectin is shown in the embryonical stage. The neural crest migration is inhibited by its exposure to fibronectin and this might hinder the embryonic development.
Thus, the answer is neural crest cell movements are inhibited.
I’m pretty sure it’s tree roots :)
Here's a picture to help explain and show the steps:
