Chloroplasts contain chlorophyll and carotenoids. Chlorophyll directly absorbs light for use in photosynthesis.
Carotenoids absorb light and transfer the energy from light to chlorophyll. The efficiency of photosynthesis varies with
the wavelengths of the light that illuminates the chloroplasts. In an experiment to study the relationship between the
incoming light wavelengths and the chemical reactions of photosynthesis using a species of green algae, a researcher
labeled the COt2 supply to the algae with 14C, and the H20 with 180.
Which of the following results is expected?
O More 14C is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red
light.

Answers

I believe the answer is A!!!!!

Agricultural technology has evolved over time, with significant leaps during the agricultural and green revolutions.

Agricultural revolution

Agriculture has been one of the sustainers (along with hunting) of early men and as such, has seen gradual development with time. Man has always been looking for better ways to do things in order to achieve outcomes.

With the era of the agricultural revolution, there was a huge transition of humans from the primitive lifestyle of hunting and fruit gatherings to that of agricultural settlements. Better ways to carry out crop production started receiving huge attention. from there, hand-made agricultural equipment started surfacing.

The green revolution has agriculture receiving utmost attention in terms of technological innovations. Farm machinery, agrochemicals, etc, started coming up with the result being a massive increase in crop production and general outputs.

6. In general, as both the force and velocity of impact increase, what happens to the diameter of
the resulting blood droplets?

Answers

Answer: depending on viscosity, mass and velocity of impact, if droplet integrity is maintained, as velocity increases, diameter will increase from

Approximately d*sqrt(2) to 2*sqrt(d^3/6a) where d is original diameter and a is thickness when the droplet flattens into a disc.

Explanation:

This applies generally to any liquid droplet, which by inference falls and impacts a solid surface. The impact force is mgh where m= mass, g= acceleration due to gravity, h= initial height.

A liquid droplet deforms on impact. Assume the drop is sperical, then the deformation distance, d= diameter of the droplet then the average impact force = mgh/d.

The droplet may spread, splash or bounce, depending on viscosity and force, which depends on mass and velocity immediately before impact.

All than can be said is that if the droplet maintains integrity it could achieve the shape of half a highly flattened oblate spheroid. Approximating this with a flattened disc of thickness a, and an original volume of 4/3pi(d/2)^3, the volume as a disc =a*pi*r^2 so the horizontal diameter = 2*sqrt(d^3/6a)

It is not really possible from the available data to determine whether the droplet would remain its integrity, but at sufficiently low force/velocity, the droplet could retain a near-hemispherical shape, giving a horizontal diameter of the hemisphere = d*sqrt(2)

As velocity increases, if integrity is maintained, the diameter will increase from the second approximation to the first

A scientist is using a microscope to observe a type of
bacteria.

Which two structures would the scientist most likely see?PLEASE EXPLAIN WHY

A:nucleus and DNA
B:DNA and cell wall
C:cell wall and vacuole
D:vacuole and nucleus

Answers

Answer:

The two structures most likely to be observed by the scientist when looking at a type of bacteria under the microscope are cell wall and vacuole (option C).

Explanation:

Bacteria are prokaryotic organisms that lack a nucleus, most of the organelles, and whose DNA is dispersed in the cytoplasm. Some types of bacteria have a plasma membrane surrounded by a cell wall, and may be equipped with vacuoles to perform their functions.

It is very likely that two structures that are most likely to be differentiated when a type of bacteria is observed under the microscope are the cell wall and the vacuole, according with information above.

The other options are not correct because:

    A and D. Bacteria lack a nucleus.

    A and B. Bacterial DNA is dispersed in the cytoplasm and is very difficult to observe under the microscope.

Which atom is involved in giving your heart energy to beat?
O carbon
O gold
O oxygen
O iron​

Answers

Answer:

Oxygen

Explanation:

-How fast the heart beats depends on the body's need for oxygen-rich blood. At rest, the SA node causes your heart to beat about 50 to 100 times each minute. During activity or excitement, your body needs more oxygen-rich blood; the heart rate rises to well over 100 beats per minute.

-The heart, like any organ, requires blood for oxygen and other nutrients so it can do its work. The heart does not gather oxygen or nutrients from the blood flowing inside it. Instead, it receives blood from coronary arteries that eventually carry blood into the heart muscle.

What should be happening to the sickle-cell allele in the United States, and what should be happening to it in equatorial Africa

Answers

Answer:

directional selection, stabilizing selection

Explanation:

Directional selection is a type of natural selection that favors one extreme phenotype over other phenotypes, thereby modifying allele frequency in the direction of the favored phenotype. This type of positive selection is the main cause of phenotypic diversification. In the USA, the environment created a selection pressure that favored individuals that don't have the defective sickle-cell allele, thereby reducing its frequency in this population. Stabilizing selection, also known as balancing selection, is a type of natural selection where the most common phenotype is selected in the population, thus predominating in future generations. In equatorial Africa, the defective sickle-cell allele is present in a high frequency because individuals that are heterozygous for this allele are less susceptible to malaria, and therefore balancing selection should maintain this allele in the African population.

Answers

Answer:

1) Create a hypothisis 2) Create experiment 3) collect data 4) write conclusion

The four steps that a scientist uses to solve a problem are creating hypothesis, experiment, data sorting and writing conclusion.

What are hypothesis?

A hypothesis is an elaboration posited for a characteristic. The scientific technique requires that a hypothesis be testable in order for it to be considered a scientific hypothesis.

Scientists typically base scientific hypotheses on previous findings that cannot be adequately explained by existing scientific theories.

Any process that co-ordinate system data into some defined order to make it simpler to understand, analyze, or visualize is referred to as data sorting.

The conclusion is the final section of an academic essay. The conclusion should restate your response to the question and briefly summarize key points. It does not contain any new points or information.

A scientist solves a problem by developing a hypothesis, conducting an experiment, sorting data, and writing a conclusion.

Thus, by using these steps, scientist can come to an end for the problem.
