The doctor who is concerned that wilma may have a brain tumor recommends that a(n) positron emission tomography (PET) scan.
PET scan is a scan imaging test that allow doctor to check disease in human body. This scan uses a special dye that contain a radio active tracer.This scan provide information about blood flow and how body is using oxygen and sugar.
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:
March and September
Explanation:
It is true because neither end of the axis is tilted toward the sun in those months. They are in spring and autumn, which are balanced unlike winter and summer. Hope this helps!
Because cellulose is required for the stem growth as cellulose is the main constituent of the cell wall and also provides toughness to the stem.
When less sunlight is in those months the photosynthesis also lowers, resulting in the use of stored energy i.e starch. Hence the starch level decreases.
Explanation:
Cellulose is required for the growth and toughness of the stem. During spring the budding and growth is fastest in plants hence supply of cellulose increases.
The starch is the energy stored in plants. It is a polymer of glucose. When sunlight decreases in some months the rate of photosynthesis lowers down and plant starts using the stored form of energy ie. starch, required for various physiological activities and growth of the plants. This is the reason the starch level decreases in plants sometimes.
II and III only. The fungus is a heterotroph, since it's not making it's own food, but it's also a Saprotroph (since it externally digests dead organic materials; saprotrophs are a special subset of heterotrophs).
