Herbicides are being used to kill weeds in a nearby field. The plants absorb the herbicides from the soil. Which organelle
in the plant will most likely store the absorbed herbicide waste?
ribosome
vacuole
chloroplast
mitochondrion
Answer:
The answer is B. Vacuole
Explanation:
As the plants have no used for the herbicides, it will be transported to it "waste bin" which is the Vacuole.
Definition of Vacuole: Vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
Also, completed a test with same question, and got it right.
Vacuole organelle in the plant will most likely store the absorbed herbicide waste.
What is Vacuole?
Animal, plant, bacterial, protist, and fungal cells all include vacuoles. It has the size of a giant sac and is one of the biggest organelles found in cells.
Vacuoles are bordered by a thin membrane and filled with fluid and any molecules they take in.
This is their basic structure. Because both are membrane-bound sacs, they resemble another organelle called vesicles, however vacuoles are substantially bigger than vesicles and are created when numerous vesicles fuse together.
Therefore, Vacuole organelle in the plant will most likely store the absorbed herbicide waste.

To protect our rights, the Constitution divides powers between the federal government's branches. This principle is called "separation of powers." Each branch of government holds distinct but equal authority. For example, Congress has the power to create laws, while the president has the power to execute these laws. The preamble states the purpose of "securing the Blessings of Liberty." Our freedoms are secured when power is not concentrated in any single branch of government. This helps our government to provide for our needs while respecting our rights.
Answer:

How the coin flip relates to the probability of inheriting genetic condition?
Answer:
A coin represents a diploid, heterozygous cell with its heads and tails sides. The act of tossing the coin to land on heads or tails, provides an apt representation of the segregation of alleles during meiosis in the formation of gametes.
or i guess you could just say its all by chance ;P
peace :)
Answer:
It is very similar to the way traits are inherited in nature, as both combinations occur by chance. Though, in the coin toss, there are only 2 possible alleles whereas in nature there may be more complicated combinations of alleles for traits.
Explanation:
Light behaves in specific ways. It can be reflected, refracted, or absorbed, and under certain conditions, run into different kinds of interference. Which explanation best describes why light is refracted as it enters water?
A. The light bends when it enters water due to its reflection.
B. The speed of light remains the same as it moves from air to water, causing the light to reflect.
C. The speed of light increases when it enters a different medium, but it doesn't bend.
D. The speed of light changes as it moves from air to water, causing the light to bend.
Answer:
D
Explanation:
Refraction is generally defined as the change in the direction of a wave as it travels from one medium to another. Light is a form of wave and light refraction is caused by a change in the speed of light as it moves from air to water, causing the light to bend in the process. The medium of travelling has to be transparent.
The change in the speed and direction is due to the variability in the refractive index of media. Light travels faster as it moves from a medium of higher refractive index to a medium of lower refractive index and vice versa.
The correct option is D.

If you ate more food from secondary consumers, how would this change the percentage of the biomass pyramid necessary to support your survival?
Answer:
would increase
Explanation:
The pyramid of biomass is a diagram that exhibits the total biomass of the organisms at different trophic levels, which are required to support life in a given ecosystem. This pyramid usually starts with producers situated on the bottom (e.g., plants), then continues with the organisms that eat these primary consumers (herbivores), after with secondary consumers (carnivores), and so successively. The pyramid of biomass indicates the amount of mass of 1-primary producers required to support the life of the primary consumers, 2- primary consumers needed to support the life of the secondary consumers, 3-secondary consumers needed to support the life of the tertiary consumers, and so successively for each trophic level. In this diagram, the trophic level with a higher amount of biomass (and energy) is usually represented by the producers (i.e., by organisms on the bottom), and this amount of biomass decreases as long as more levels are considered. In consequence, if more food from secondary consumers is consumed, it will produce an increase in the percentage of biomass that is needed to support life.

The diagram below shows the exchange of carbon dioxide (CO2) and oxygen (O2) between a cell and the blood flowing through a capillary.
In this diagram, the molecules of CO2 (represented by x’s) are moving from an area of--
Answer:
From an area of higher concentration to an area of lower concentration.
Explanation:
The molecules of CO2 are moving from an area of higher concentration to an area of lower concentration. Carbondioxide is produced as waste product in the cell during the process of respiration. This carbondioxide gas is loaded in blood cells because in the cell, concentration of carbondioxide gas is higher while on the other hand the concentration of carbondioxide is lower in the blood cells. This carbondioxide gas exchange in the lungs with oxygen which is required in the process of respiration for the production of energy in the form of ATP molecules. So from the conclusion we can say that CO2 moves from an area of higher concentration to lower concentration.
