jeka57 [31]3 years ago
4 0

Answer:

Temperatures gradient

Explanation:

There are distinct temperature gradient differences in the layers of atmosphere usually due to the main air molecule composition of the layers, the density of the molecules. The Troposphere the lowest layers is the densest and temperature decreases with increase in altitude. The stratosphere, on the other hand, has an increase in temperature with increase in altitude. Temperatures decrease with altitude in the mesosphere while the parameter increases with altitude in the thermosphere.

One species of plant produces flowers when nights are 10 hours long. a related species comes into flower when nights are 9 hours
STALIN [3.7K]

Temporal isolation is the type of reproductive isolation that would include this example.

Temporal isolation is a type of reproductive barrier in which two closely related species (plants or animals) are prevented from mating and producing sterile hybrids because of their different breeding time. The difference in the breeding time may be year, season (such as fall or winter) or by time of day (daytime or at night).

When you a red bird mates with a white bird mate all the offspring have pink feathers. What can best explain this observation?
MrRa [10]

Answer:

Incomplete dominance

Explanation:

Incomplete dominance is a type of non-mendelian inheritance pattern in which one allele of a gene is not dominant or recessive to the other allele, hence, both alleles combine to form a third intermediate phenotype, which is a blending of both parental phenotypes.

In this case, a red bird (RR) mates with a white bird (WW) to produce offsprings that have pink feathers (RW). This shows that the allele for red coloration is incompletely dominant to the allele for white coloration, hence, both combines to produce a PINK (RW) intermediate phenotype. This portrays incomplete dominance.

e following are important steps in the process of endochondral ossification. What is the correct order for these events? 1. Enla
creativ13 [48]

Answer:

The correct order for these events is 3, 1, 5, 4, 2

Explanation:

Endochondral ossification is referred to as the process of bone development from hyaline cartilage. Cartilage is systematically replaced by bone to form the growing skeleton. Endochondral ossification process involves chondrocytes enlarge and the surrounding matrix begins to calcify, enlarged chondrocytes die, perichondrial cells become osteoblasts and produce a superficial layer of bone, blood vessels grow around the edges of the cartilage, and osteoblasts replace calcified cartilage with spongy bone.
