Pollination occurs at the ovary of a pistil, the female reproductive organ of a flower. true or false.

What evidence for the endosymbiotic hypothesis

Whitepunk [10]

Answer:

The evidence suggests that these chloroplast organelles were also once free-living bacteria. The endosymbiotic event that generated mitochondria must have happened early in the history of eukaryotes, because all eukaryotes have them

36. Breezes are named

77julia77 [94]

The correct answer is - D- for the feature they blow from.

The breezes have all sorts of names, most of which tend to be derived from the feature they flow from. Lot of winds are named after the side of the world that they come from, so there's easterlies, westerlies, northern winds, southern winds. Some are maned after a river, as they flow along side it, like Vardarec. Some may be named after a mountain, or just have a name similar to a mountain, like mountain wind, forest wind, gorski vetrec.

Some winds, on the other hand, have names that describe their force, especially that goes for the strong ones, like bura along the Croatian coast on the Adriatic Sea.

A group conducted a survey of two different plots on campus. Both plots had 100 trees in them. Plot 1 had 85 maples, 5 birch, 5

nirvana33 [79]

Answer:

d. The species diversity of plot 2 is greater than that of plot 1.

Explanation:

Species diversity of an area depends on its species richness and species evenness. Species richness is the number of species present in that area. Species evenness measures how evenly these species are distributed.

Here, both plot 1 and plot 2 have same number of species. They both have four species of trees ( maple, birch, oak and pine) hence their species richness is same. However plot 1 has 85% maple trees and the rest three species make the remaining 15%. Plot 2 has more even distribution as 35% of trees are maple trees and birch and oak also have similar frequency with 25% and 35% respectively. Hence, plot 2 has more evenness.

Species diversity depends on both richness and evenness. Since plot 1 and 2 have same richness but plot 2 has more evenness, plot 2 has more species diversity than plot 1.

In the previous question, you used the Hardy-Weinberg equation to determine the frequencies of the genotypes for HH, Hh, and hh,

Oxana [17]

The expected number of each organism in the population is HH = 60, Hh = 48, hh = 96.

<h3>What is the Hardy-Weinberg equation?</h3>

The hardy-Weinberg equation is a mathematical equation used to calculate the genetic variation of a population at equilibrium.

The given frequencies are HH = 0.04

Hh = 0.32

hh = 0.64

So, the percentages are HH = 4%, Hh = 32%, hh = 64%.

The total percentage will be (4 + 32 + 64 = 100)

The total size is 150

Now,

The number of HH genotype is 0.4 × 150 = 60

The number of Hh genotype is 0.32 × 150 = 48

The number of hh genotype is 0.64 × 150 = 96

The total is 6 + 48 + 96 = 150

Thus, the expected number of each organism in the population is HH = 60, Hh = 48, hh = 96.
