Answer:
Pretty sure its #3
Explanation:
Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. ... The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.
Answer:
A
Explanation:
The darker moths would be harder for the bird to see due to the amount of soot on the trees. The darker moth population would thrive and continue to grow, while the lighter colored moth population would decrease.
Answer:
Sun > Grass > Deer > Lion
Explanation:
The sun begins a food chain because its light is needed for a plant, in this case grass, to grow.
An animal that eats grass is the deer, who is a primary consumer.
An animal that eats deer is the lion, who is a tertiary consumer in this case.
The lion has no natural predator, and thus is at the top of this food chain.
This ecosystem can be one found where grass, deer and lions exist, for example, the deciduous forest in the eastern United States.
39%. Adenine would have the same percentage as Thymine, meaning it would he 32% A and T and then subtract that from 100 giving you 72 divide that by 2 and you get part Guanine and part Cytosine.
Answer:
E
Explanation:
Gregor Mendel discovered the principles that governs heredity. In one of his experiments, he discovered that an organism receives two forms of a gene called ALLELE from each parent. He realized that one allele is capable of masking the expression of its variant pair in a gene. He called the allele that masks or is expressed, DOMINANT allele while the allele that is masked, RECESSIVE allele. He termed this principle the LAW OF DOMINANCE.
The above explained law of dominance is what applies in the question here. When the homozygous round allele and wrinkled allele were crossed, the allele for round seeds are dominant over the allele for wrinkled seeds (recessive) i.e. in a heterozygous state (combination of the different alleles), the round allele will mask the phenotypic expression of the wrinkled allele, expressing itself over it.
