The level that is used in nuisance contaminations that are
present and requires the lowest form of chemical or respiratory protection is
the level d. This level requires use of protection that are only minimal such
gloves, booths, safety glasses, mask or shield.
♥Bacteria
♥Dehydration
♥The nutrients could be sucked out
♥Plant diseases
♥Dead plants
♥Hope this helps!
Answer:
A nutrient can be described as a substance which is used for the survival, growth and reproduction of an organism.
Three nutrients which plants require are:
NITROGEN (N): Nitrogen is important for growth and immunity. Without nitrogen, the plant will not be able to grow or produce immunity.
PHOSPHORUS (P): Strengthens root systems, capacity for seed creation, disease resistance, and pest prevention. Improves flowers and blooming. Also strengthens tissues and flavors in edibles and veggies. Without phosphorus, plants will not be able to produce sweet fruits.
CALCIUM
Strengthens and fortifies overall tissues everywhere. Also helps neutralize acidity, both within the plant and in its surrounding soil, for optimal health.
Answer:
The correct option is : b. centrosome
Explanation:
Centrosome is a cell organelle, which acts as the microbule organizing center and also regulates the cell cycle progression in an eukaryotic cell.
During the prophase stage of the cell cycle, the centrosomes are associated with the membrane of the nucleus. The nuclear membrane ruptures during the mitosis and the interaction of the centrosome nucleated microtubules with the chromosomes leads to the formation of the mitotic spindle.
<u>Therefore, mitotic spindles arise from the centrosome.</u>
Answer:
the fact that rod functioning predominates during dark adaptation, therefore poor acuity
Explanation:
- Rods and cones are the photoreceptor cells present in the eye that perform the function of converting the light received into signals that stimulate the biological processes.
- Out of the rods and cones, the rods are more sensitive and they are so sensitive that they can be activated even under low light conditions.
- However the cones can be stimulated only under bright light conditions, but the visual acuity is higher for the cones as compared to the rods.
- <em>Therefore under conditions of dim light, the rods are activated and hence it results in a poor visual acuity and a person experiences difficulty in reading. </em>
