A group of students wants to study the rate of photosynthesis under various conditions. They use a blender to mechanically disru

Answer:

B

Explanation:

The statement that best explains the result would be that the rate of photosynthesis is greatest for direct sunlight and least for the infrared light.

The DPIP will normally replace and play the role of NADPH in the light reaction of the process of photosynthesis. Hence, it will become colorless as a result of reduction and the rate of photosynthesis can be monitored based on the magnitude of the disappearance of the dark blue color.

It means that the more colorless the liquid in the illustration is, the more the rate of photosynthesis. The color change moved from dark blue to clear colorless under direct sunlight, from dark blue to nearly colorless under indirect sunlight, and from dark blue to slightly lighter under the infrared light. This clearly indicates that the rate of photosynthesis is highest under direct sunlight and lowest under infrared light with the indirect sunlight having an intermediate rate.

The correct option is B.

What are the differences in their hard parts, distribution, reproduction among phytoplankton of cyanobacteria, diatom, coccolith

Margarita [4]

Answer:

Explanation:

DIFFERENCES BETWEEN HARD BODY PARTS.

•Cyanobacteria have calcified sheaths.

• Diatoms have hard but porous cell wall.

• Coccolithophores have hard body parts.

• Silicoflagellates skeleton is composed of opaline silica.

• Dinoflagellates do not have hard body parts

• Green algae - no hard body parts.

• Brown algae - no hard body parts.

DIFFERENCES BETWEEN DISTRIBUTION

• Cyanobacteria are found almost in every terrestrial habitat on planet.

• Diatoms are found in oceans, freshwater, soil and damp.

• Coccolithophores are exclusively marine.

• Silicoflagellates are found in marine environment.

• Dinoflagellates are both freshwater and marine.

• Green algae grow on objects that do not move such as substrate, rock.

• Brown algae - wide distribution from tropical to polar zones.

DIFFERENCES BETWEEN REPRODUCTION.

• Cyanobacteria - asexually by binary or multiple fission, fragmentation, spore formation.

• Diatom - asexually by cell division through mitosis.

• Coccolithophores - asexually by binary fission.

• Silicoflagellates - asexually

• Dinoflagellates - asexually

• Green algae - sexually or asexually by cell division, fragmentation, spore formation.

• Brown algae - sexually and asexually.

In the following table, label each statement as true (T) or false (F). If the statement is false, rewrite it so that it is true.

iren [92.7K]

1) False. Scientists may predict something but realize a difference soon after before the test, so they could definitely change the hypothesis if they want. It’s only AFTER the experiment they cannot. Because a hypothesis is like a “guess” as to what’s going to happen, right?

2) False. A hypothesis can’t be “valid” because it’s literally a prediction.

3) True. Especially if you’re doing a chemistry lab, it’s really important things are done in order or else the product might result as something else you were expecting, or can be very dANGEROUS

4) True. The conclusion must be based on data because it’s the observation that was seen.

Hope this helps!! I could have answered in short form but I just wanted to make them understandable:)

The diagram below represents a flower, the reproductive structure of some plants. Most

Evgen [1.6K]

Answer:

The stigma, a female structure which collects pollen and passes it to the ovary

Explanation:

The structure represented by the letter A in the diagram is the stigma.

The stigma of a flower represents part of the female reproductive structure. The surface of a mature stigma is sticky and as such, it is able to attract pollen grains from the anther. A pollen that lands on the stigma germinates and its pollen tube grows through the style of the stigma down to the ovule where one of the sperm cells of the pollen fertilizes the egg cell of the ovule to form a diploid zygote and the other sperm cell fuses with the polar nuclei of the ovary to form a triploid cell that eventually becomes the endosperm.

The sepal and the petal are labeled as D and C in the diagram respectively while the stamen is made up of B and H.

An individual having two different alleles of a specific gene is described as being _________ for that specific trait.

borishaifa [10]

An individual having two different alleles of a specific gene is described as being Heterozygous for that specific trait.

You have a heterozygous genotype for that gene if the two versions differ. Being heterozygous for hair color, for example, means you have one allele for red hair and one allele for brown hair. The interaction of the two alleles influences which traits are expressed.

Being homozygous for a gene means you inherited two identical copies. It is the inverse of a heterozygous genotype, in which the alleles differ. People with recessive characteristics, such as blue eyes or red hair, are always homozygous for that gene. In genetics, heterozygous means having inherited different versions (alleles) of a genomic marker from each biological parent. As a result, a person who is heterozygous for a genomic marker has two distinct versions of that marker.
