What are the reactants for photosynthesis?
Answer:
well the chloroplasts are the part of the cell that make photosynthesis happen
Answer:
light energy, water, carbon dioxide, and chlorophyll.
Explanation:
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.
O More 180 is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red
light
O More 14C is found in the algae when it is illuminated by blue-violet and red light than when it is illuminated by green
light.
O More 180 is found in the algae when it is illuminated by blue-violet and red light than when it is illuminated by green
light

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

c. Suppose a large population of turtles consists only of two species, snapping turtle and box turtle, but the percentage of the species in the population are unknown. What is the maximum possible value of the diversity index D for the population
Answer:
[tex]D_m=1/2[/tex]
Explanation:
From the question we are told that
2 species
Assuming that questions a and be are solved
Diversity index D=2p_1p_2
with [tex]p_1 +p_2 =1[/tex]
Mathematically
[tex]D=2p_1(1-p_1)[/tex]
[tex]D=2(p_1-p_1^2)[/tex]
[tex]D=2({\frac{1}{4} -(p_1-1/2)^2}[/tex]
Therefore
[tex]D=\frac{1}{2} -2(p_1-1/2)^2[/tex]
Giving
[tex]D_m=1/2[/tex]
[tex]p_1=1/2[/tex]
Mike created the following table... what needs to be corrected
Answer:
The outer core is liquid and the inner core is solid.
Explanation:
This statement is true, the inner core is not liquid it's solid.
The outer core is liquid and the inner core is solid. The opportunity cost of 1 chair is 1/5 table for Mike and 1/3 table for Sandy.
What is cost opportunity?Opportunity cost of the next best option forgone when one alternative is chosen over other alternatives. In order to determine the opportunity cost of making chairs, divide the number of tables made for each person by the number of chairs.
Mike's opportunity cost in making one chair = 4/20 = 1/5
Sandy's opportunity cost in making one chair = 6/18 = 1 / 3
Petrifcation can be defined as the process in which the organic material of the dead living being becomes fossil by the replacement of mineral deposition in the bony, hard material. Thus, although the body components gets decomposed wiped out due to this process. The body shape of the dead organism remains the same as that was in living.
Therefore, The is liquid and the inner core is solid. The opportunity cost of 1 chair is 1/5 table for Mike and 1/3 table for Sandy.

Flagellants atoning for sinsGovernments quarantining all those who fell illShutting down tradePrayingWhat is a plague?A plague is a highly infectious and often fatal disease caused by the bacterium Yersinia pestis. The most infamous outbreak of the plague occurred in the 14th century in Europe, killing an estimated 25 million people, or one-third of the population. The disease is typically spread through the bite of an infected flea, although it can also be transmitted through contact with infected animals or humans.
There are three forms of the plague: bubonic, septicemic, and pneumonic. Bubonic plague is the most common form and causes swollen lymph nodes, fever, chills, and fatigue. Septicemic plague affects the bloodstream and can cause fever, chills, abdominal pain, and vomiting. Pneumonic plague affects the lungs and can cause fever, cough, chest pain, and difficulty breathing.
Today, the plague is rare but still exists in some parts of the world, including Africa and Asia. Early diagnosis and treatment with antibiotics are essential for successful treatment of the disease.

1. A dominant gene (A) causes yellow color in rats, the dominant allele on another independent gene (R) produces black coat color. When the two dominants occur together (A_ R_) they interact to produce gray coat color. Rats of the genotype aa are cream-colored. If a gray male and a yellow female, when mated, produce offspring approximately 3/8 of which are yellow, 3/8 gray and 1/8 cream, and 1/8 black, what are the genotypes of the parents
Answer:
Parents: Yellow (Aarr) and Grey (AaRr)
Explanation:
Given:
allele A = yellow
allele R = black,
Heteroozygous = gray
Genotypes of the parents:
yellow (Aarr) - female
gray (AaRr) - gray
cross between these
Parents: Yellow (Aarr) and Grey (AaRr)

Explanation:
At what points in the progression from gene to protein do these methods act (i.e., what processes do they prevent)
Answer:
Genes are translated, transcribed and after these two steps, the formation of a protein takes place.
DNA is translated, that is, read, in the form of codes and thanks to the machinery of intracellular transcriptases, after this an RNA is encoded that will be made with the assembly of amino acids that together will form proteins.
Proteins can be structural or functional.
Explanation:
There are different methods to intervene in these processes, it can be by means of macromolecules, drugs and also by microbiological factors, that is, by microorganisms such as viruses that take advantage of the human transcription machinery to replicate.

Which animals are the main consumers of the Pan dropseed (Sporobolus ioclados) ?
Answer:
elephants
Explanation:
The animals that are the main consumers of the Pan dropseed are all animals have complex organ systems. Especially Seed-eating birds including American sparrows, and elephants.
What is Sporobolus ioclados?The grass family contains a nearly universal genus of plants called Sporobolus. The genus' members are frequently referred to as dropseeds or sacaton grasses.
They grow in numerous sorts of open habitat in warmer temperatures and are typical grassland and savanna plants. At least one species, as well as another, are endangered.
Only alkali sacaton has the little moth Bucculatrix sporobolella's caterpillar been discovered (Sporobolus airoides).
On Laysan Island, it appears that the local elimination of S. virginicus by feral rabbits led to the extinction of the Laysan dropseed noctuid moth (Hypena laysanensis).
All of the animals that eat the Pan dropseed most frequently have intricate organ systems, including seed-eating birds including American sparrows, and elephants
Thus, these are the animals that are the main consumers of the Pan dropseed.
