Does the color of a leaf affect the rate at which that leaf photosynthesizes

Yes and no. If you're comparing two healthy leaves of different species that have different leaf colors, then probably not. However, a yellowed or bleached leaf (unhealthy) will photosynthesize at a different rate, if at all.

sun and shade leaves also photosynthesize at different rates, and will have different colors.

How are mitosis and meiosis similar

they both produce new cells(apex)

they both have prophase and metaphase (anaphase)

They both involve duplicating chromosomes.

they both have simular steps.

What happens during interphase

the chromosomes are duplicated.

What is the purpose of transcription

Transcription is the process in which part of the nucleotide sequence of DNA is copied into a complementary sequence RNA. Transcription is helps to preserve the spoken way that allows it to be easily stored and examined in the future. Transcription allows a piece to be referenced in the future.

What is produced by meiosis

Reproductive cells-- egg or sperm cells--or produced by meiosis.

Why did mendel use pea plants in his experiment

They produce many offspring

How are tumor cells different from normal cells

Mitosis is not regulated in tumor cells. This can cause the rapid proliferation of a large number of non-functional cells, whose only actions are to divide into more cells.

Tumor cells multiply too quickly.

What evidence did Mendel find that supported his law of independent assortment

One trait does not affect whether another trait will be passed on. -Apex

An organism that reproduces sexually has a diploid number of 40 How many chromosomes will a gamete of this organism have

20

How do the daughter cells produced by mitosis compare to the original cell

The daughter cells are identical to the original cell.

What happens directly after prophase

Metaphase

A plant can have either brown B or red b leaves Brown is the dominant trait If a plant has genotype bb which best describes the plant

Homozygous with brown leaves

A cactus can either have long needles L or short needles l A cactus grower crosses two cacti what is the result what is the phenotype ratio for the cross

3 long, 1 short

What happens right before transaction begins

Negotiation.

The table below shows the number of chromosome pairs for various organisms. Which organism can produce the highest number of genetically different gametes
