What are Vacuoles?Vacuole may be defined as a type of membrane-bound cell organelles that is present in the cytoplasm of plants, fungi, some protists, and animals. In plant cells, the size of the vacuole is comparatively larger as compared to other living organisms including animals.
In plants, the vacuole stores a large amount of sugar in order to facilitate its development and growth. Apart from this, it also regulates the storage and transport of substances in and out of the cell. It stores all sorts of impurities inside in order to protect the cell from contamination.
Therefore, the products that can be found in vacuoles are sugars, water, water-soluble pigments, etc. Thus, the correct option for this question is D, i.e. all of these are found in vacuoles.

A. The Soviet Union had pretended to be capitalist until 1945
B. The Communists did not take over until after the war
C. When Joseph Stalin took over, the relationship changed
D. Cooperation was necessary to fight Germany and Japan
Answer: D I think
Explanation:
Before 1945, the US and USSR worked well together mainly because cooperation was necessary to fight common enemies, Germany and Japan, during World War II. Thus, correct option is D.
In order to fight Nazi Germany and Imperial Japan, the US and USSR forged an alliance during World War II. The two nations momentarily put their ideological differences aside to concentrate on the shared threat, which is how the partnership came about. During this time, both countries provided one another with military assistance and basic resources.
It is crucial to remember that the alliance began to deteriorate following the war as conflicts developed between the capitalist US and the communist Soviet Union. The Cold War, which was defined by rivalry and mistrust between the two superpowers during the post-war period, heralded a substantial change in their earlier cooperative relationship.

Which of the following statements is TRUE?
A. When muscles contract they become longer.
B. Involuntary muscle can be identified by its unique striped appearance.
C. The biceps and quadriceps are an antagonistic pair.
D. The origin of a muscle is attached to the bone that does NOT move.
"The origin of a muscle is attached to the bone that does NOT move" is true among the following statements.
The origin and insertion of an attachment are the points of attachment. When a muscle contracts, the point of attachment known as the origin remains stationary. As a result, when contraction occurs, the origin bone is the more immobile of the two bones at the joint.
Skeletal muscles have two or more points of attachment to bone, or occasionally to other muscles or tissues. The attachment is said to as having an origin if the location is a bone that is stationary during an action. The attachment is referred to be an insertion if the location is on the bone that moves during the motion.
The triceps brachii has four places of attachment: three origins and one insertion on the ulna (two on the humerus and one on the scapula).

Explanation:
Within a population of butterflies, the color brown (B) is dominant over the color white (b) and 32% of all butterflies are white. Given this simple information, which is something that is very likely to be on an exam (teehee), calculate the following:
12% of butterflies in the population have homozygous dominant genetic makeup. If there were 4,216 people in the population, then there would be 48% heterozygous butterflies.
What is Hardy-Weinberg's principle?In the absence of other evolutionary factors, the Hardy-Weinberg principle asserts that allele and genotype frequencies remain constant from generation to generation.
Brown (B) outnumbers white (b) in proportion to the population's characteristics.
Recessive phenotype frequency
(Q)= 40%
Q = 0.4
According to the Hardy-Weinberg principle, the frequency is given by P and Q for a population with the dominant and recessive trait, where P+Q=1 preserves the equilibrium of the population allele.
So then, P = 1-Q
P = 1-0.4
P = 0.6
Heterozygotic butterflies = 2PQ
So, 2PQ= 2x0.6x0.4
=0.48
So, 48% of the population is heterozygous.
Homozygous dominant individual frequency = 1 - (40 + 48) = 12 i.e. 12%.

Which of the following would indicate the closest relationship.
Two organisms in the Kingdom Animalia
Two organisms in the Phylum Cordata
Two organisms in the Genus Homo
Two organisms in Domain Eukarya
Two organisms in the Genus Homo would indicate the closest relationship.
The extant species Homo sapiens (modern humans) and several extinct species categorized as either ancestral to or closely related to modern humans (depending on the species) are all included in the otherwise extinct genus Australopithecus, where the species Homo first appeared.
The most notable of these extinct species are Homo erectus and Homo neanderthalensis. The first individual of the genus, Homo habilis, emerged just over 2 million years ago. Homo, along with the genus Paranthropus, is most likely related to Australopithecus africanus, which had previously diverged from the Pan, or chimpanzee, branch.
The scientific name of the genus Homo implies that its constituent species can be categorised as humans. Furthermore, over the course of the 20th century, fossil discoveries of early human and pre-human creatures from the late Miocene and early Pliocene produced a diverse range for classification debates.

How can long term use of one drug such as aspirin increase your tolerance to a different drug such as alcohol that you have never encountered
Long-term use of one drug increases tolerance to different drugs because these compounds need to bind the same receptors for to produce a given effect.
How does drug tolerance develop?The expression drug tolerance makes reference to higher concentrations of drugs required to produce the same effect due to the rate between a drug and its receptors in the cell.
This phenomenon (drug tolerance) is associated with the increase of the concentration of a given drug to produce the same effect due to the ligand-receptor relationships between both variables.
Different drugs use the same receptors in the cell to bind and trigger a given signaling pathway, thereby one drug may increase the tolerance of another substance.
In conclusion, long-term use of one drug increases tolerance to different drugs because these compounds need to bind the same receptors for to produce a given effect.

Which describes redshifts? Check all that apply.
The light source and observer move closer together.
Observed light shifts to a longer wavelength.
They indicate receding galaxies.
Observed light shifts to a shorter wavelength.
The light source and observer move farther apart.
They indicate approaching galaxies.
Answer:
Observed light shifts to a longer wavelength.
They indicate receding galaxies.
The light source and observer move farther apart.
Explanation:
Red light is the lowest frequency visible light, violet is the highest frequency (hence INFRA-red, as in below red and ULTRA-violet, as in above violet).
Redshift is an effect where we observe light (from space) that we'd otherwise expect to be higher frequency than observed.
Redshift is an effect very similar to Doppler's effect, where we hear lower (lower frequency) sounds when moving away from a sound source.
Because we're moving away from the light source (or the light source moves away from us). Similarily, when you're driving, you'll pass more cars going the opposite way than those going along with you.
So, when a galaxy recedes (and fast!) we'll observe the light frequency to be lower than the galaxy actually emits. Lower frequency = higher wavelength.
To conclude - any answer that relates to the light being lower frequency, or higher wavelength, or the observer and source moving apart are good answers, whereas those that suggest the opposite are bad answers.
