What type of reaction does catalase facilitate- synthesis or decomposition? Why?
Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.
Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.
What is catalase?
An enzyme called catalase causes (catalyzes) the process by which hydrogen peroxide is broken down into water and oxygen.
Catalase, which is widely distributed in organisms that live in the presence of oxygen, inhibits the buildup of peroxide, which is continuously created by multiple metabolic reactions, and shields cellular organelles and tissues from harm. Catalase is primarily found in the liver of mammals.
Numerous industrial uses exist for catalase. It is used with other enzymes in the food industry to preserve foods, make particular dishes and beverages, and preserve foodstuffs.
Therefore, Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen.

• How does precipitation affect the topology of the earth?
Answer: Global Climate Change. comes from precipitation. Too little precipitation can result in dry soil, shallow streams, and shortages of municipal water supplies. However, too much precipitation can also have a negative impact on human activities, business and industry, agriculture, and the environment. As moist air is forced up the windward slope it expands and cools, eventually causing water droplets to condense when the air is saturated. These droplets form clouds and grow to produce rain or snow that typically falls out on the windward side of the range. ... As air approaches the topography, it slows down.
Explanation:
Precipitation affects the topology of the earth positively and negatively ( excess precipitation leads to soil erosion while moderate precipitation repairs broken/dry soil surfaces making it fertile )
Precipitation has a positive and negative effect on the topology of the earth because excessive precipitation like heavy rainfall causes flooding and the heavy movement of flood water, washes away the surface soil ( erosion ) which affects the topology of the earth negatively. while
Moderate precipitation repairs dry and broken soil surfaces making the topology of the earth fertile, supporting the growth of plants and inhabitation of animals .
Hence we can conclude that precipitation affects the topology of the earth positively and negatively.

Describe the different types of traits that exist.What factors can affect these traits?
Answer:
Cardinal traits, central traits, and secondary traits.
Explanation:
There are three types of traits according to the Gordon Allport which organized traits into three levels that is cardinal traits, central traits, and secondary traits. Factors that affect these traits are the environmental factors as well as genetic factors. Some of these traits acquire by an individual through inheritance while on the other hand, other traits can get by the people through the exposure to environment that leads to the presence of that traits.

What makes the distribution of traits in a population change?
Answer:
The Genetic Variation in a Population Is Caused by Multiple Factors. Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing environmental circumstances.
Explanation:
The distribution of traits in a population are subject to change due to genetic variations and the environmental factors. Mutations also play an important in change of traits in a population.
What are mutations?Mutations are described as the sudden change or variation in the heredity material - DNA of an individual. Mutations leads to change in the genetic composition of an individual. Such mutations can be favourable by the environment or can be discarded by the nature or remain unaffected.
Mutations can occur during the cell-division or during the replication of DNA. It can be also occur due to some external agents. The occurrence of mutation is not predicted however it is identified only after a considerable change is observed in the phenotypic character of an individual.
Mutations are of four main types:
Point mutationsChromosomal mutationsSomatic mutationsGerm line mutationsThus, there are various agents that probably cause mutations upon exposure. Such agents are called mutagens.

Refer to the Biochemistry in Focus section of your text for this chapter to answer this question. A mutation in Complex I decreases the efficiency of the electron transport chain. However, not all components of the electron transport chain are affected by this mutation. Which component of the electron transport chain will remain unaffected by a mutation in Complex I
Answer:
Complex II
Explanation:
The electron transport chain refers to a group of electron transporters embedded in the inner mitochondrial membrane that transfer electrons from electron donors to electron acceptors which undergo redox (reduction and oxidation) reactions. The energy released during the transfer of electrons is coupled to the transfer of protons (H+) from the mitochondrial matrix into the intermembrane space, generating an electrochemical gradient that is then used to synthesize ATP. Complex I and Complex II are membrane-bound complexes that act as mitochondrial redox carriers. Complex I is a proton pump that uses energy from the electron transfer chain to pump protons, while Complex II sends H+ onto Complex III in the form of the reduced ubiquinol. Complex I receives electrons from NADH and transfers them to ubiquinone, while Complex II directly receives the redox cofactor FADH2 that does not pass through Complex I.

Earth's polar regions have cold, dry climates because the Sun's rays are at a
1
low angle, and upper atmospheric air is sinking
2
low angle, and upper atmospheric air is rising
3
high angle, and lower atmospheric air is sinking
4.
high angle, and lower atmospheric air is rising
Answer:
1. low angle, and upper atmospheric air is sinking
Explanation:
Weather can be defined as the atmospheric conditions of a particular area over a short period of time. Some of the elements of weather are wind, humidity, temperature, air pressure, precipitation and clouds.
Basically, the weather of a particular area or region may change hourly, daily, monthly or even annually.
On the other hand, climate refers to the change in the atmospheric conditions and manifestation of weather in a particular area over a long period of time usually 30 years.
In Science, Earth's polar regions refer to the areas that are typically located between the North Pole and the Artic Circles or South Pole and the Antarctic Circles.
The very cold temperatures found in polar regions causes the air to be very dry and as such there's no much atmospheric moisture; reducing the amount of precipitation (rain, sleet, snow or clouds) drastically.
At higher altitudes (heights above sea level), the angle of incidence of the sun's ray (sunlight) is usually at a low angle striking the tilted surface of the Earth.
Hence, Earth's polar regions have cold, dry climates because the Sun's rays are at a low angle, and upper atmospheric air is sinking, which leads to an increase in the amount of heat received.
Earth's polar regions have cold, dry climates because the Sun's rays are at a low angle, and upper atmospheric air is sinking.
Climate of a Polar RegionThe two most important factors in the climate of an area are temperature and precipitation. The temperature of Polar areas are in negative because the sun's rays strike these areas at very low angles.
Due to very cold temeperature there is no moisture in the air, and hence the air is very dry, this is why the Precipitation in Polar areas is too low. Hence, the polar region have cold, dry climates. Therefore, as per above statment we can say that the correct option is 1. Low angle, and upper atmospheric air is sinking.

Which of the following is not a characteristic of enzymes?
Each is used to break down substances.
Each has a specific substrate.
Each has an optimal temperature and pH.
O
Each has an active site.
Answer:
Each is used to break down substances.
Explanation:
Enzymes merely speed up a chemical reaction, not necessarily break down substances.
Each enzyme is used to break down substances is not a characteristic of enzymes. The correct option is A.
Thus, enzymes aren't just utilized to degrade things. Enzymes perform additional crucial tasks in addition to being essential for the breakdown (catabolism) of substances. In living things, enzymes operate as biological catalysts to quicken chemical processes.
Enzymes achieve this by reducing the activation energy needed for a reaction to happen and thereby speeding up the reaction rate. While some enzymes are engaged in the breakdown of chemicals, others are involved in the synthesis or modification of other molecules (anabolism).
Thus, the ideal selection is option A.

Question 7 0410
The process of
releasing energy
is when two stoms combine to form a larger atom,
Answer here
Answer:
Nuclear fusion
Explanation:
Nuclear fusion is a process whereby the nuclei of two smaller atoms combine to form a much larger atom, accompanied with the release of energy. This is opposed to nuclear fission where a larger atom splits into simpler and smaller atoms.
According to this question, the process of releasing energy when two stoms combine to form a larger atom is called NUCLEAR FUSION. A very common example of nuclear fusion is the combination of hydrogen atoms in the sun to produce Helium atom, with the release of heat energy.
Let’s think about mutations in the context of selection and evolution. Normally, random mutations are very rare, but this process can be accelerated by using DNA damaging agents. Imagine you are working with yeast. Normally, high levels of salt kill yeast. However, you are conducting a random genetic screen to find salt-tolerant mutants. You use a DNA damaging agent (like EMS, or UV light) to damage the yeast DNA, then look for growth on plates with salt.
a. Does putting the yeast on salt cause the beneficial mutation? Why or why not?
b. If you screened your mutagenized yeast cell population on caffeine (another substance that normally kills them), could you find caffeine tolerant ones? (assume there is the potential for genetic resistance to caffeine).
a. Does putting the yeast on salt cause the beneficial mutation? Why or why not?
When the logarithmic growth of cells is interrupted by exposure to a 0.5 to 2 Molar salt solution the aueous solution consisting of KCl, NH4Cl, NaCl, MgCl2 are basically mutagenic in yeast .
Stationary phase cells are not mutated by the treatment.
b. If you screened your mutagenized yeast cell population on caffeine (another substance that normally kills them), could you find caffeine tolerant ones? (assume there is the potential for genetic resistance to caffeine).
For normal tolerance to caffiene the sty1 and pap 1 pathways are not necessary, but generally only sty1 is activated by mutation hence making yeast sensitive for caffiene.

How does a medicine like Benadryl (a medicine taken to suppress allergy symptoms) affect the immune system?
Research the effect of insulin on blood sugar after a meal. You may use outside sources. Select the correct statement. Insulin has no effect on blood sugar. Insulin increases blood sugar. Insulin reduces blood sugar.
Answer:
Insulin reduces blood sugar.
Explanation:
Insulin is an hormone produced naturally in the pancreas organ of the body. Insulin is majorly involved in digestion where it helps in the absorption process. Insulin aids the absorption of glucose by cells.
When a meal is eaten, the food digests and breaks down into GLUCOSE, which enters into the blood stream via the small intestine. Insulin ensures that the sugar (glucose) content in the blood REDUCES by moving glucose into cells for respiration (energy production) and storing the excess glucose as glycogen in the liver cells.
