One difference between algae and plants is that _____.
Zolol [24]

Answer: plants have roots, stems, or leaves

Algae and plants are similar organisms because both are autotrophic organisms which are able to produce their own food by the process of photosynthesis. The main difference between the two is the level of complexity. Algae are comparatively simple organisms, their structure ranges from single celled to multi-cellular organisms. They do not exhibit true roots, stems and leaves like plants. The plants exhibit complex specialized structure for transport of water, nutrients and to perform reproduction. The smallest to largest plant will exhibit roots, stems and leaves.

Population A consists of 100 hens that are fully isogenic and that are reared in a uniform environment. The average weight of th

Answer:

a. the environmental variance (VE) = 3.5 g ²

b. 17.5 g ² for population

c. the heritability of broad sense (H2) = 0.83

Explanation:

a.With the information we have we can infer that environmental factors influence A, which is considered isogenic, thus, the environmental variance (VE) = 3.5 g ²

b.When studying population B, comparing it without environmental changes with respect to population A, we found that its total variance (VT) = 21.0g ²

We generate the following formula with the data obtained previously to find the genetic variation

VT = VE + VG

then VG = VT-VE

replacing data:

VG = 21.0 - 3.5 = 17.5 g ² for population

c. Regarding the heritability of broad sense (H2) in population B, we can reach the result with the data previously obtained like this:

H2 = VG / VT = 17.5 / 21.0 = 0.83
