a key feature of enzymes is that they _____.
a. interact generally within cells
b. are changed by reactions
c. are carbohydrates
d. are not used up in reactions
e. force reactions to occur
Answer:
d. Are not used up in reactions
Explanation:
This is a property of enzymes. They are not used up since they don't participate in reactions. They just help increase the rate at which it occurs
A key feature of enzymes is that they force reactions to occur. Thus, the correct option for this question is E.
What are Enzymes?Enzymes may be defined as biocatalysts that increase the rate of a chemical reaction without being changed in the overall process. It may be thought that all sorts of cellular reactions or processes are mediated by enzymes.
Most of the enzymes are proteins. They are highly specific in nature. Enzymes also exhibit enormous catalytic power. They do not alter the equilibrium state of biochemical reactions.
Enzymes typically speed up the rate of a chemical reaction by lowering the activation energy of a particular reaction. Thus, it leads to the conversion of reactants into products at a faster rate.
Therefore, a key feature of enzymes is that they force reactions to occur. Thus, the correct option for this question is E.

The heart pumps oxygenated blood to the _____ and deoxygenated blood to the _____. A) body:liver B) body:lungs C) brain:lungs D) lungs:nose Eliminate
Answer:
The Answer is B) body:lungs
Explanation:
The body sends oxygenated blood (blood enriched with oxygen) to the body where oxygen is used and blood becomes deoxygenated. This blood when received in heart is pumped to Lungs where oxygen is taken up by blood through alveoli in our lungs. This way deoxygenated blood gets oxygenated and is pumped to the rest of the body and the cycle repeats.
All other options are wrong as blood can only get oxygenated at lungs through small air chambers called alveoli where oxygenation takes place.

The Benefits of Communism
Theoretically, there are many benefits that can be achieved through a communist society. Communist ideology supports widespread universal social welfare. Improvements in public health and education, provision of child care, provision of state-directed social services, and provision of social benefits will, theoretically, help to raise labor productivity and advance a society in its development. Communist ideology advocates universal education with a focus on developing the proletariat with knowledge, class consciousness, and historical understanding. Communism supports the emancipation of women and the ending of their exploitation. Both cultural and educational policy in communist states have emphasized the development of a “New Man”—a class-conscious, knowledgeable, heroic, proletarian person devoted to work and social cohesion, as opposed to the antithetic “bourgeois individualist” associated with cultural backwardness and social atomization.
Other theoretically beneficial ideas characteristic of communist societies include:
People are equal. In a communist regime, people are treated equally in the eyes of the government regardless of education, financial standing, et cetera. Economic boundaries don’t separate or categorize people, which can help mitigate crime and violence.
Every citizen can keep a job. In a communist system, people are entitled to jobs. Because the government owns all means of production, the government can provide jobs for at least a majority of the people. Everyone in a communist country is given enough work opportunities to live and survive. Every citizen, however, must do his or her part for the economy to receive pay and other work benefits.
There is an internally stable economic system. In communism, the government dictates economic structure; therefore, economic instability is out of the question. Every citizen is required to work in order to receive benefits, and those who don’t have corresponding sanctions. This creates an incentive to participate and to encourage economic growth.
Strong social communities are established. In communism, there are certain laws and goals which determine resource and responsibility allocation. If the citizens abide by these laws, this leads to a harmonious spirit of sharing one goal. Consequently, this builds stronger social communities and an even stronger economy.
Competition doesn’t exist. In communist societies, everyone can work harmoniously without stepping on each other’s toes. Work, responsibility, and rewards are shared equally among the citizens. If people have no sense of envy, jealousy or ambitions that counter the goals of the state, then a harmonious economic development can be maintained.
Efficient distribution of resources. In a communist society, the sense of cooperation allows for efficiency in resource distribution. This is very important, especially in times of need and in emergency situations.

Cual seria el recorrido de una molecula de glicosa desde que es absorbida en el intestino delgado hasta que es metabolizada en el cerebro ?
Answer:
Del intestino delgado ---- torrente sanguíneo --- célula u órgano de almacenamiento.
Explicación:
Después de la absorción de glucosa por el intestino delgado, las moléculas de glucosa se difunden por un gradiente de concentración hacia la sangre capilar dentro de las vellosidades y estas moléculas de glucosa se liberan en el torrente sanguíneo. Cuando las moléculas de glucosa se agregan al torrente sanguíneo, la glucosa puede usarse para la producción de energía o almacenarse en nuestros cuerpos, que puede usarse cuando sea necesario. Si nuestro cuerpo necesita energía esta glucosa es absorbida por las mitocondrias de las células para la producción de energía mientras que por otro lado, si no se requiere energía, estas moléculas de glucosa se almacenan en diferentes órganos en forma de glucógeno.

7. The diagrams show stages in the passage of water through a plant,
The circles are the starting points for arrows to show the direction in which the water moves.
Which circle must have an arrow pointing downwards only?
From the understanding of how water moves through plants, the only circle that can have a downward pointing arrow only is A.
Water moves through a plant in the following direction:
Soil ----> root -----> stem ----> leaves
Once water gets into the root from the soil, a conducting tissue known as xylem conducts the water upward through the stem of the plant branching off into the leaves through the petiole. from the petiole, water is then conducted to the mesophyll cells.
Circle D represents the root, so the arrow must be upward.
Circle C represents the stem, the arrow continues upward towards the leaves
Circle A and B represent the leaf. The movement of water within the leaf might requires that it is from circle A to circle B. Hence, the only circle that must have an arrow pointing downward only can only be A.

6 Which of the following statements about shark teeth fossil evidence is not consistent with the scientific theory of evolution? (7 Points) A. Many fossils of Shark teeth have recently been found that are all the same size and color compared to modern sharks. B. Many fossils of Shał teeth have been found that show different sizes and serrations (saw-like edges). These fossil teeth have distinct differences and similarities to modern sharks. C. Many fossils of Shark scales have been found that have features of enlarged scales that resemble a brush. Our modern sharks do not have or need this type of scale to survive. D. A new shark fossil has been found that has characteristics in the size of the teeth and the serrations (saw-like edges) that are in between the older fossils found and the modern shark.
Answer:
A. Many fossils of Shark teeth have recently been found that are all the same size and color compared to modern sharks.
Explanation:
Evolution is the change in characteristics of a species over time and it relies on the process of natural selection.
The theory of evolution states that all species are related and gradually change over time.
Since all options except A show a change in the characteristics of shark teeth in the fossils found in relation to modern sharks, option A is the answer. Since, there is no change in characteristics between the Shark teeth in the fossils and that of modern sharks.
So, option A is the answer.
