Answer:
1.5mm
Explanation:
According to this question, Mary is trying to view 5 pollen grains under her microscope. She found out that the 5 pollen grains each with a diameter of 0.3mm could fit along the diameter of the field of view of her microscope.
This means that the diameter of the field of view of Mary's microscope can be calculated as follows:
Diameter of each pollen × no. of pollen that fit in
= 0.3mm × 5
= 1.5mm
Hence, the diameter of the field of view of Mary's microscope is 1.5mm.
The diagram presented represents hydrolysis of sucrose.
<h3>What is hydrolysis of sucrose?</h3>
The hydrolysis of sucrose generates an equimolar mixture of fructose and glucose, commercially known as invert sugar.
Sucrose is a disaccharide with the formula C₁₂H₂₂O₁₁.
On hydrolysis, Sucrose yields the two monosaccharides, namely;
- glucose (aldohexose) and
- fructose (ketohexose),
However, on dehydration Sucrose produces a complex carbonaceous solid residue.
Thus, the diagram presented represents hydrolysis of sucrose.

Your neurons carry messages in the form of electrical signals called nerve impulses. To create a nerve impulse, your neurons have to be excited. Stimuli such as light, sound or pressure all excite your neurons, but in most cases, chemicals released by other neurons will trigger a nerve impulse.
There are choices for this question namely:
a. Fungi rely on the wind to disperse their spores, whereas plants have multiple means of dispersal.
b. Spores do not have their own nutritional supply and often do not land in a suitable environment that provides nutrients.
c. Spores are produced asexually and so are less genetically robust.
d. Animals eat the developing mushrooms before they have a chance to mature.
The correct answer is that spores do not have their own nutritional supply and often do not land in a suitable environment that provides nutrients. Spores more often than not transported through air and lands randomly, usually in an unsuitable environment. Spores also do not have their own nutritional supply unlike seeds of plants which contain endosperm as nutrient source.
Answer:
Organisms such as hydra use regenerative cells for reproduction in the process of budding. In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals.
