Answer:

1) alternate, opposite and whorled

2) the primary functions Of the stem are to support the leafs to conduct water and minerals to leafs, where they can be converted into usable products by photosynthesis

3) stesms stores food, water, and nutrients. cells of steam , meristems, produce new living tissues. underground stem, aerial stem and subaerial steam are three different stem

4) the are six elements 1 nodes 2 internodes 3 terminal or apical bud 4 lateral or axillary bud 5 petiole 6 pedecel. while the two organd are 7 leaves and 8 flowers

5) roots = in botany that parts of vascular plant normally underground FUNCTIONS are anchorage of plant absorption of water and dissolved minerals and conditions of these to stem, and storage of reserve foods

Explain in detail how galen, a physician during the middle ages, expanded on hippocrates’ theory of the four humors and explain

Ann [662]

<span>Hippocrates believed that there are four humors in human body which need balance for a healthy being. These were:
Blood, phlegm, yellow bile, and black bile.</span>
Galen expanded the idea of the humors and introduced four temperaments which were these:
choleric (hot / dry), melancholic (cold / dry), sanguine (warm / moist), and phlegmatic (cold / moist).
Another expansion Galen did was that he gave each humor/temperament physical and psychological qualities and said that even the food items have an association with the certain humor, those foods can effect certain humor in certain ways.

Kisachek [45]

One hypothesis that explains the result is : A) Two genes are involved with 12:3:1 epistasis, such that A_B_ and A_bb are black, aaB_ is brown,and aabb is green.

Explanation:

This is a case of Dominant Epistasis.
When two genes are involved and presence of dominant allele of one gene masks the effect of either allele of the second gene then the epistasis is termed as dominant epistasis.
In the given case black :brown: green ratio is approximately equal to 12:3:1.
Here presence of a dominant A allele that is responsible for the black colour masks the effect of either allele of B. Therefore A_B_ and A_bb produces black beetles
Again , absence of dominant A allows B to express itself and Brown beetles are produced thus aaB_ is brown.
When both the genes are present as recessive alleles, neither brown nor black colour is expressed and the beetles are green.Thus, aabb are green.
