Answer:

a) and b) All the 12 plates taken by the food controller for the analysis are test plates in light of the fact that the food inspector is trying distinctive spinach from 10 unique bundles and do try different things with every one of the 12 plates.

C) and D).only #11 plate is a negative control since he utilized the spinach which isn't cleaned. so microorganisms can develop on that pate because they have the positive condition to develop themselves.

e) and f). all #1 - #10 and #12 plates are positive control plates since he swipes all the plates and spinach that can be the reason for the development of microbes so there is an excess of fewer opportunities to the defiling of spinach and he is playing it safe.

Answer:

Point A - Intrusive igneous rock

Point B - Extrusive igneous rock

Explanation:

Intrusive igneous rocks are rocks which is formed by molten magma that cools and solidifies below and within the surface of the earth, thereby forming large crystals beneath the earth surface. Examples of Instrusive igneous rocks gabbro, granite, peridotite etc.

Intrusive Ignoeus rock is formed at point A in the diagram given above.

Extrusive Ignoeus rock, on the other hand, is the opposite of Intrusive igneous rock. Extrusive igneous rock is formed when molten rocks, called magma, erupts from beneath the earth and cools and solidifies on the surface of the earth, thereby forming small crystallized rocks. Examples of extrusive igneous rocks are basalt, pumice, etc.

Extrusive Ignoeus rocks would formed at point B in the diagram above.

Which plants are likely to be infertile or to have reduced fertility? Check all that apply. Check all that apply. Species with a

Lemur [1.5K]

D. Species with an odd number of chromosome sets (triploid and pentaploid) would be infertile.

E. Aneuploid individuals (monosomic and trisomic) would have reduced fertility.

Explanation - Chromosomes generally happens to occur in the set of two. Organism that have more than two sets of chromosome are called polyploids. Polyploids that have odd or uneven count of sets of chromosome are sterile or fully infertile.

Example - triploid (3n), pentaploid (5n) because their gametes and offsprings are aneuploid. Aneuploidy is addition of entire chromosome to the already existing normal set of chromosome. Aneuploids are unable to produce viable offspring because their fertility got decreased as the zygote formed after the fertilization itself is aneuploid.
