Answer:
<em>Read explanation.</em>
Mold:
Molds are a type of fungus with a multicellular growth (opposite of yeasts) and tend to grow in hot and warm but also humid environment.
Explanation:
A hypothesis is an idea of what is causing a problem or the what the origins of the problems are.
In this case, a possible hypothesis is that the "molded" side of the bread is having a different exposure to the external environment, such as hot/warm but humid/<em>wet-ish</em> conditions.

Answer:
Option (1), (3) and (5).
Explanation:
Positive feedback mechanism also exist in the environment that increases the causative effect of the environment. The environment can change the temperature, precipitation and other climatic conditions of the area.
The lack of moisture in Sahara desert and deforestation can cause the trees extinction. The temperature can be increased by the green house gases as the warm atmosphere causes evaporation. The snow gets melted due to increase in temperature and the ground becomes more darker.
Thus, the correct answer is option (1), (3) and (5).
The answer to this question is C
Answer:
Pigmented snails: A_B_; albino snails: A_bb, aaB_, aabb
This is an example of recessive epistasis. In recessive epistasis, two recessive alleles mask expression of an allele at a different locus. The 9:7 ratio observed in this question is a special case of epistasis called duplicative recessive epistasis, which means the presence of either aa or bb was sufficient to mask expression of the other gene. In this case, if snails had two copies of either allele a or allele b, pigment production was suppressed, resulting in albino individuals.
Answer:
The starch in the plant was removed
Explanation:
When a plant is placed in a dark cupboard for 24hrs it won't receive any sunlight meaning it won't photosynthesize. This results in the plant using up it's stored starch for growth. It is at this point where one can test if sunlight is necessary for photosynthesis to take place. The answer to this will then be, yes.
