Answer: C. It has a small temperature range during summer.

Both taiga and alpine biomes are cold regions. The alpine is the coldest biome of the world. In both alpine and taiga biomes temperatures are below freezing during the winter, both exhibit low annual rainfall, both have two distinct seasons but alpine biome has a small temperature range during summer as these are present in high altitudes. In summers exhibit temperature range of -12 degree Celsius to 10 degree Celsius which is a small temperature range.

Colored aleurone in the kernels of corn is due to the dominant allele R. The recessive allele r, when homozygous, produces color
abruzzese [7]

Answer: C. It was heterozygous for both genes.

Explanation: To produce a generation that has individuals with trait for colored aleurone in the kernels, the plant being analised has to have a dominant allele R. In the same way, to have offspring with the recessive trait, it has to carry the recessive allele r. So, the unknown plant has to be heterozygous for colored aleurone in the kernels, Rr.

The same thought can be applied to plant color: Since there are green and yellow plants, the unknown plant has to be heterozygous for that trait, Yy.

In conclusion, the unknown plant is heterozygous for both genes.

Rhonda Runsalot is a 20 year old woman. She is running at VO2max. Her heart rate is 200 b/min. Her stroke volume is 100 ml blood
katen-ka-za [31]

Answer:

Cardiac output = 20 L/min

Explanation:

The cardiac output of a person refers to the volume of blood the heart pumps in a minute. The normal range for cardiac output is about 4 to 8 L/min. However, this can vary depending on the metabolic needs of the individual at any instant of time, for example, it is higher when exercising than  when resting.

Cardiac output is calculated from the product of the stroke volume in liters/min and the heart rate in beats/min

Cardiac output  = stroke volume * heart rate

For the individual who is running; stroke volume = 100 mL/beat or 0.1 L/beat

heart rate = 200 beats/min

Cardiac output =0.1 L/beat * 200 beats/min

Cardiac output = 20 L/min

How does independent assortment increase genetic variation in Meiosis?
KIM [24]

Answer:

Independent assortment produce new combinations of alleles.

Explanation:

In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis. It results in gametes that have unique combinations of chromosomes.
