The correct answer is: B) As land plants became more complex, animal life did as well.
This is because land could not be colonized by other organisms such as animals until land plants became established-there was nothing for animals to feed on.
So, plants were one of the earliest organisms to leave the water and colonize land.
Answer:
B. 100 percent yellow seeds
Explanation:
When a gene has two alleles and one allele is dominant over the other, the dominant allele is expressed in the heterozygous state and the expression of the recessive allele is masked. According to the given information, the allele for yellow seed color is dominant over the allele for the green seed color.
Let's assume that the allele "Y" gives yellow color to the seeds while the allele "y" is responsible for green seed color. A cross between two pure breeding yellow seeded (YY) and green seeded (yy) plants would produce all the yellow seeded progeny with genotype "Yy".
YY (Yellow) x yy (green) = Yy (yellow)
It is transplanted routinely to treat a variety of blood and bone marrow diseases, blood cancers, and immune disorders. More recently, stem cells from the blood stream (called peripheral blood stem cells) and umbilical cord stem cells have been used to treat some of the same blood-based diseases
Answer:
4 I think
Explanation:
The cytoplasm is home to many activities of the cell as it contains molecules, enzymes that are crucial in the break down of the waste. The cytoplasm also assists in metabolic activities. Cytoplasm provides shape to the cell. It fills up the cells thus enabling the organelles to remain in their position.
Answer:
because it is hard to breakdown fat in a very short time while ATP can be broken down in a very short time.Fats have a very strong bond of molecular chains and this makes it hard to breakdown quickly
