The botanist wanted to produce a generation of snapdragons that all had pink flowers.
State the phenotypes of the parent plants that the botanist would need to cross.
Explain your answer.
Answers
Answer:
He would need to cross one homzygous red (RR) and homzygous white (rr)
Explanation:
Flower color in snapdragons is controlled by a gene whose alleles exhibits incomplete dominance. The allele for red coloration (R) is incompletely dominant over the allele for white coloration (r). The intermediate phenotype that is produced in an heterozygous state (Rr) is PINK.
According to this question, a botanist wanted to produce a generation of snapdragons that all had pink flowers (Rr). This means that in order to do this, the botanist would need to cross a red snapdragon plant (RR) and a white snapdragon plant (rr) to produce an 100% Pink (Rr) snapdragon in the F1 generation.

Human blood is 90% water and 10% solute. What would happen if you gave
a patient an IV of pure water (0% solute)? The patient's cells will
remain unchanged.
swell or lyse.
shrivel.
Answers
Answer:
When a person receives fluids intravenously (through an IV bag, for example), a saline solution is sometime used. Giving large amounts of pure water directly into a vein would cause your blood cells to become hypotonic, possibly leading to death.
Explanation:
The answer is B: It swells.
A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

A baker activates yeast cells with hot water, and adds sugar as their source of food. As the yeast begin their metabolic processes, the bowl it is in is covered with plastic so that no oxygen can get to them. At this point, the yeast will __ *
1 point
a. produce far more ATP than is necessary in response to the lack of oxygen
b. continue to go through aerobic respiration if enough sugar is present
c. die since all living organisms need oxygen to survive.
d. perform anaerobic respiration in the absence of oxygen
Answers
Answer:
The correct answer would be - option D. perform anaerobic respiration in the absence of oxygen.
Explanation:
Yeast is a facultative anaerobic single-cell organism that can live without oxygen. If yeast cells did not get the oxygen they use anaerobic respiration to get the energy.
If the baker activates these cells and stops them to get oxygen the yeast cells have to switch to anaerobic respiration to survive and produces ethanol and releases carbon dioxide.

Alice and her friends looked at a bunch of ladybugs. They noticed the ladybugs had different numbers of spots. They each had different ideas about why the numbers of spots were different.
This is what they said: Which person do you agree with the most?
A) Karen: I think they must all be different species of ladybugs.
B)Troy: I think each ladybug has the same number of spots as its parents.
C)Isaac: I think it depends on the age of the ladybugs. As they get older they add more spots.
D)Fred: I think it has to do with the sex of the ladybug. Males will add more spots to compete for the females.
E) Andrea: I think it depends on what each ladybug was born with.
F) Alice: I think they change their number of spots when there is a need for them to do so.
Explain your thinking. Describe your ideas about why the ladybugs look different.

Marine iguanas feed on seaweed. Seaweed contains starch Starch is digested by enzymes in the digestive system. Explain why the shape of an enzyme is important for digestion.
Answers
Answer: The enzyme is a catalyst that speed up the rate of the reaction.
Explanation:
The enzyme can be defined as the protein that is involved in the catalytic activity of the reaction. The shape of the enzyme is important as it determines to which substrate it binds to. The enzyme is specific to the substrate and binds to a specific kind of substrate. During the digestion process the enzyme binds to the specific substrate like protein, carbohydrates, fats, and other biomolecules present in the food to simplify the digestion process. Starch is digested into maltose by the enzyme salivary amylase in the mouth.

What is the effect of an increased concentration of calcium ion in the sarcoplasm?
Answers
Answer:
When calcium concentration increases during depolarization, it shifts the conformation of troponin and tropomyosin, and actin is able to associate with myosin. As calcium is taken up again by the sarcoplasmic reticulum the muscle cell relaxes.
The effect that can be associated with increase in concentration of calcium ion in the sarcoplasm is :
Changing of shape and position of tropomyosin.
Can also cause muscles stiffness.
When the Ca2+ concentration become high in the sarcoplasm, there would be change in the position of tropomyosin as result of the binding effect of Ca2+ binds on troponin.Then the tropomyosin will be moved away from myosin binding sites on actin, then a cross bridge will be formedHowever, the effect if this on muscles is muscles stiffness.

The collision between an oceanic and a continental plate, or two oceanic plates originate volcanoes. a) oceanic crust at convergent boundary b) heats up.
What are convergent boundaries?Collision area between two plates. Two continental plates might collide, or two oceanic plates, or one oceanic plate with a continental one.
In the last two cases, the thicker and older plate subduces under the other plate, and magma rises to the surface by crevices. The Himalayas and Los Andes are examples of these collisions.
Plates' movement might produce earthquakes. Also, collisions create volcanic arches and continental arches.
When one of the plates sinks under the other one, it reaches a depth where it melts and magma rises. Volcanoes get formed on the superior plate since magma flows over it.
