Answer:
D. The rest of the country has only evergreen trees, so autumn is much less colorful in those areas.
Explanation:
The deciduous birch forests of the eastern United States have been reducing their territory by anthropic action. Yet in Florida it still persists. In these forests, plants such as birches do not support the harsh winters and that is why they have the strategy of losing their leaves. they start to turn their yellow leaves in the fall season. In other areas of the country where there are coniferous forests, grasslands and grasslands, trees have other strategies and generally have evergreens trees.
Answer:
A., Vision. Eyes contain two types of photoreceptors called rods and cones.
The wind makes pollination possible for gymnosperms. In gymnosperms ovaries are absent and the gametophytes of these plants are present on cones rather than flowers. Unlike angiosperms that get pollinated with animal interference, wind plays a crucial role in gymnosperm pollination.
Answer:
Tt - 2/4 = 1/2 or 50% Heterozygous TALL
tt - 2/4 = 1/2 or 50% Homozygous Dwarf
Explanation:
So let's make a Punnett for this so you can see what the outcome is yourself:
Tall is <u>dominant</u> - T
Dwarf is <u>recessive</u> - t
Heterozygous means that they have one of each allele. The genotype of one parent would be then Tt.
***It is heterozygous tall because Tall is a dominant trait so if it is accompanied by the recessive trait dwarf, then the Tall allele would mask it.
The other parent is a dwarf plant. The genotype would then be tt.
*** Now for a recessive trait to appear, it should not have a dominant trait mixed with it, which could mask it. The result then is homozygous recessive or homozygous Dwarf.
So now that we know the genotypes of the parent plants, we can put it into a Punnet:
t t
T Tt Tt
t tt tt
As you can see, out of the 4 outcomes we have:
Tt - 2/4 = 1/2 or 50% Heterozygous TALL
tt - 2/4 = 1/2 or 50% Homozygous Dwarf
