Phototropism occurs when a plant bends in the direction of a light source. A common light source is the Sun. The plant hormone auxin is released in response to the Sun. What causes the plant to bend toward the light?
A.The hormone auxin causes cells on the shady side of the plant to elongate.
B.The hormone auxin causes cells on the lighted side of the plant to elongate.
C.The hormone auxin causes cells on the shady side of the plant to shrink.
D.The hormone auxin causes cells on the lighted side of the plant to shrink.
Answer:
A.
Explanation:
Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs.
A hurricane passes through the Gulf of Mexico and destroys many of the coastal regions of Northwest Florida,
Which of the following is a likely impact of this catastrophic event on biodiversity?
Species brought in by the storm surge will displace species native to the coastal wetlands.
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of
habitat.
Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity
will increase in these areas.
Excessive salt from the storm surge will flood coastal wetlands and raise salinity to intolerant levels for the
local species, causing a decrease in biodiversity
Answer:
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of
habitat.

A kid on a trampoline has 1,000 J of potential energy when they are at the top of a jump. How much kinetic energy will the kid have when they come halfway down?
A. 100 J
B. 250 J
C. 500 J
D. 1000 J
Answer:
C. 500 J
Explanation:
Given;
potential energy of the kids at the top of the trampoline, P.E = 1,000 J
⇒At the top of the trampoline, the kids have only potential energy.
⇒On half way down, the kids have both kinetic energy and potential energy.
⇒At the bottom of the trampoline, the kids have only kinetic energy.
Based on the statements above, the kinetic energy of the kids half way down is calculate as;
P.E + K.E = 1000 J
Base on law of conservation of energy, P.E = K.E
2 K.E = 1000 J
K.E = ¹/₂ x 1000 J
K.E = 500 J.

A man with blood group B marries with a woman with blood group AB and the daughter has blood group AB. Is this information enough to tell you which of the traits – blood group B or AB is dominant? Why or why not?
Answer:
YES. This information is enough to assume that neither of the blood groups dominates over the other one.
Explanation:
Available data:
A man with blood group B ----> Genotype IBIB or IBiA woman with blood group AB ---> Genotype IAIBTheir daughter has blood group AB --> Genotype IAIBThe fact that the daughter´s genotype is IAIB tells us that she got the IA allele from the mother, who is IAIB, and the IB allele from his father, who is IB-.
If blood type B was dominant over A or AB, then the daughter should have Blood type B. If blood type A was dominant over B or AB, then the daughter should have Blood type A. Blood type AB tells us that both types are being expressed, A and B.The fact that the daughter inherited one type of allele from each parent, but she is expressing the blood type AB, suggests that neither of the alleles dominates the other one. This is an example of co-dominance, where the heterozygote phenotype is an additive expression of both of the parents' genes.
This is enough information to assume that neither of the blood groups dominates over the other one.
Which of the following does not exist during prophase?. Single choice.
A. Condensation of chromatins
B. Disappearance of nuclear membrane
C. Pairing of homologous chromosome
D. Chromosomes lined up in the middle of the cell
Option 2
Answer:
Option B.
Disappearance of nuclear memberane.
Explanation:
This is because Prophase is marks the beginning of mitosis, and it is the process where replicated genetic contents are separated into daughter cells. During prophase, ttgere is condensation of chromatin. The chromatin coils and it become compact, which lead to the formation o chromosomes that are visible. The sister chromatids are joined together at the centromere. The mitotic spindle begins to form. The mitotic spindle is consist of long proteins called microtubules that firms at opposite end. The spindle separate the two sister chromatids.

EXPLAIN HOW A DEER TICK COULD INFECT YOU WITHOUT YOU REALIZING IT
Answer:
Because ticks stay attached to hosts, blood feeding for several days, they secrete novel pain killers, called kininases, in their saliva which help them go unnoticed. If you have been bitten previously, you may notice a small red bite mark, which can be itchy.
Explanation:
Answer:
The deer tick is tiny, no larger than a pencil point.
Explanation:
Most tick bites are harmless and don't need medical treatment. But some ticks (like the deer tick, wood tick, and others) can carry harmful germs that cause diseases like Rocky Mountain spotted fever and Lyme disease. The deer tick is tiny, no larger than a pencil point. Which mean it could bite you without you realizing it.

Helium has an atomic number of 2. Is the model of the helium atom above is
showing an ion? Explain why or why not.
Answer:
Yes, the model of the helium atom is showing an ion.
Explanation:
Helium, with an atomic number of 2, should have 2 protons and 2 electrons; however, the model only depicts 1 electron. That means the helium must have lost an electron, making it a +1 charge and an ion.

Can you tell me about cellular respiration and photosynthesis? I do not understand.
Answer:
Photosynthesis is the process in which plants make their on food; Cellular respiration is the process through which cells convert sugars into energy.
Explanation:
Answer:
the job of photosynthesis is to turn energy from the sun into chemical energy that can be used for food. Cellular respiration is the cycle that occurs in the mitochondria of organisms to break down sugar in the presence of oxygen to release energy

What is the main characteristic of the bacteria domain?All living things are classified into kingdoms based on specific characteristics found in organisms in that kingdom.
For the bacteria kingdom, the main characteristic present is that they lack a well defined nucleus as well as nuclear membrane.
Organisms without a well-defined nucleus are known as prokaryoytes.

As a cell grows larger, what happens to the surface area-to-mass ratio?
Answer:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. ... That is why cells are so small.
Explanation:
If the cell expands beyond a certain size, not enough material can cross the membrane quickly enough to accommodate the increased cellular volume.
What is surface area-to-mass ratio?The surface area to volume ratio is simply the surface area divided by the volume of an object. It expresses the proportion of surface area per unit volume of an object, such as a sphere or cylinder.
Smaller single-celled organisms have a high surface area to volume ratio, allowing them to survive by diffusing oxygen and material into the cell and waste out.
The greater the surface area to volume ratio, the more efficient this process can be.
Smaller cells have a much higher surface area to volume ratio, allowing material to diffuse quickly and efficiently throughout the entire volume of the cell.
Thus, the surface area to mass ratio will be smaller as a cell grow larger.
