Answer:
B There will be blue colonies only
Explanation:
This screen in called the blue white screening. This is a rapid test that allows scientist to check for their insert of choice in the colonies at a glance. The concept is that where the insert is located the <em>lac Z </em>gene in the vector is interrupted and therefor Xgal, a reporter can be produced. Where there are blue colonies being formed the plasmid has self-ligated and the <em>lac Z</em> gene is not interrupted and the X-gal can be formed rendering a blue color.
Answer:
Structure. The IVC is formed by the joining of the left and right common iliac veins and brings collected blood into the right atrium of the heart. It also joins with the azygos vein (which runs on the right side of the vertebral column) and venous plexuses next to the spinal cord.

Answer:
- Organism A is most likely a herbivore
- Organism B is most likey a carnivore
Explanation:
Based on feeding habit, organisms, usually animals, can be classified into three categories namely: herbivores, carnivores and omnivores.
- Herbivores are those organisms that feed on vegetative matter i.e. plants while carnivores are those organisms that feed on flesh of other animals or organisms. Based on what they feed on, herbivores are adapted to possess blunt teeth (for chewing) like Organism A in this question while carnivores are adapted to possess sharp teeth (for tearing flesh) like Organism B.
Based on the above explanation, organism A is most likely a HERBIVORE while organisms B is most likely a CARNIVORE.
- Another notable point of difference between herbivores and carnivores, which is likely to differentiate organism A and B as well, is that herbivores possess digestive enzyme- amylase in their saliva while carnivores do not. Herbivores need AMYLASE to break down complex carbohydrate (starch) in the plants they feed on.
It is called a gene, so the answer is b. gene
Answer:
B. Fossils showed that all species are the result of gradual changes over time.
