Bilaterians, for example, are all triploblastic.

<h3>Comparative embryology</h3>

Comparative embryology is a major branch of embryology that deals with comparison of the embryo of different species, thereby showing there relationships.

Triploblastic animals are those animals that have three embryonic germinal layers which include ectoderm, endoderm and mesoderm.

Which of these processes does not require the cell to use energy A cell division b protein synthesis c DNA replication D diffusi
weeeeeb [17]

Answer:

D diffusion across a membrane

Explanation:

Based on whether or not energy input is required, there are two types of processes viz: passive and active. Passive processes are those that do not require energy input in form of ATP while active processes require energy input to occur.

An example of passive process is DIFFUSION, which is the movement of molecules from a region of high concentration to a region of low concentration across a membrane. Diffusion is passive i.e does not require energy, because movement occurs down a concentration gradient.

Other processes in the options like cell division, DNA replication and protein synthesis all require energy input to occur.

In a flowering plant, blue flower (B) trait is dominant to white flower (b) trait. A true-breeding blue flower plant (BB) is cro
scoundrel [369]

Answer: D. 100%

Explanation:

One parent is with is a true breeding blue flowering plants this means the two alleles of the genotype are homozygous dominant alleles (BB).

The other parent is a true breeding with flowering plant, this means the two alleles of the genotype are homozygous recessive alleles (BB).

When both parents are crossed, the possible genotype outcome is

B B  *  b b

Bb Bb Bb Bb

Therefore since the blue flowering plant allele (B) is dominant to the white flowering plant allele (b) the probability of an offspring outcome to be a blue flowering plant is 4/4 which is 100%.44

Answer is 100%

How does the mining industry make use of bacteria?
blagie [28]

Answer:

Using Bacteria such as Acidithiobacillus ferrooxidans to leach copper from mine tailings has improved recovery rates and reduced operating costs. Microbial leaching is especially useful for copper ores because copper sulfate, as formed during the oxidation of copper sulfide ores, is very water-soluble.

16. Explain why pollution caused the shift in the phenotypes of the peppered moth during the Industrial Revolution. (2pts)
andrey2020 [161]

Answer/Explanation:

Pollution during the industrial revolution caused trees to become covered with soot, making them darker. This dark appearance meant that the peppered moth, which usually had a light colour, was clearly visible against the tree. This meant it was easier for predators to identify. As a result, their numbers decreased because they were an easier target.

However, there was also a rarer form of the moth, which was dark in colour. These were initially very rare. However, because of the change in the tree colour owing to the industrial revolution, these moths were better suited to the environment, as they were more camouflaged against the dark tree. This meant it was easier for them to avoid predators, and so they were more likely to survive to reproductive age and pass on the genes that produce the dark colour.  This meant that the dark moths increased in number.
