Answer: Enzymes are incredibly versatile, each catalyzing a huge number of biological reactions.
An enzyme behaves like both a heterogeneous and a homogeneous catalyst.
Explanation:
Enzymes are the biological catalyst they speed up the rate of the reaction without being consumed in the reaction. It is versatile in terms of catalyzing huge number of biological reactions but every enzyme has a specificity for a reactant or substrate. An enzyme can work as both homogenous and heterogenous catalyst. Homogenous catalyst is the one which is similar in properties as that of the substrate and heterogenous catalyst is the one which is dissimilar in properties as that of the substrate.
The correct characteristics is that of the action of an enzyme, enzymes are enormously efficient, much more so than synthetic catalysts.
Uses of enzymesEnzymes are biological substances that has the ability to increase the rate of a chemical reaction without changing at the end of the reaction.
The features of an enzyme include:
They possess great catalytic power and a small amount can easily catalyze a chemical reaction.They speed up reactions but remain unchanged during the whole reaction.There are synthetic and biological enzymes. The biological enzymes are enormously efficient, much more so than synthetic catalysts because biological enzymes has more affinity for its substrate than the synthetic enzymes.

genetic engineering is widely used in the field of agriculture and medicine. justify the impact of genetic engineering on humans and the environment.
Answer:
Biotechnology is the use of biological techniques and engineered organisms to make products or plants and animals that have desired traits.
Explanation:
People have used biotechnology processes, such as selectively breeding animals and fermentation, for thousands of years. Late 19th and early 20th century discoveries of how microorganisms carry out commercially useful processes and how they cause disease led to the commercial production of vaccines and antibiotics. Improved methods for animal breeding have also resulted from these efforts. Scientists in the San Francisco Bay Area took a giant step forward with the discovery and development of recombinant DNA techniques in the 1970s. The field of biotechnology continues to accelerate with new discoveries and new applications expected to benefit the economy throughout the 21st century.
In its broadest definition, biotechnology is the application of biological techniques and engineered organisms to make products or modify plants and animals to carry desired traits. This definition also extends to the use of various human cells and other body parts to produce desirable products. Bioindustry refers to the cluster of companies that produce engineered biological products and their supporting businesses. Biotechnology refers to the use of the biological sciences (such as gene manipulation), often in combination with other sciences (such as materials sciences, nanotechnology, and computer software), to discover, evaluate and develop products for bioindustry. Biotechnology products have made it easier to detect and diagnose illnesses. Many of these new techniques are easier to use and some, such as pregnancy testing, can even be used at home. More than 400 clinical diagnostic devices using biotechnology products are in use today. The most important are screening techniques to protect the blood supply against contamination by AIDS and the hepatitis B and C viruses.

See Concept 40.4 (Page) determined when the organism is vigorously exercising after consuming a fatty meal the total amount of energy an animal uses in a unit of time typically higher in an ectothermic animal than in an endothermic one the amount of heat gained by an animal in a unit of time directly proportional to body size
Answer:
The correct answer is ''the total amount of energy an animal uses in a unit of time''
Explanation:
The general metabolism or metabolic requirements can be defined as the energy demands that an organism requires for the set of biochemical reactions and physicochemical processes that occur in its cells. This set of reactions allows living beings to grow, reproduce, keep their physical structures in order and respond to external stimuli, among other things. Basal metabolism or Metabolic Rate (BMR) refers to the rate of energy expenditure (the amount of energy [expressed in kilocalories or megajoules (MJ)]) per unit of time that is spent when endothermic animals are in physical rest full. In other words, it is the amount of heat (expressed in calories) that is generated in one hour by an endothermic animal kept at rest. Also, it can be expressed as kilocalories per hour or per kilogram of weight.
Compare the movement of oxygen and carbon dioxide across the cell membrane. (4 marks)
help pls answer in paragraph form :)
Answer:
Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.
The mitochondria creates carbon dioxide (CO2) as a waste product of cellular respiration (the process that makes energy for your body). Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell. It too is small and uncharged so it can pass through cell membranes easily.
These movements require no energy (in the form of ATP) on behalf of the cell.

A small number of birds arrive on an island from a neighboring larger island. About twice a year, one or two more birds from the neighboring island arrive. These new arrivals: Group of answer choices tend to speed up adaptation to new food plants speed up the process of speciation accelerate differentiation between the two populations tend to slow divergence of the two populations
Answer:
Hello. None of the answer options is correct, as the new arrivals delay adaptation to new food plants.
Explanation:
The arrival of new birds increases competition for food. This makes the birds that have just arrived have some difficulty in accessing food, as they will have to compete with the birds that are already on the island. This makes the novice birds look for food plants they already know, which delays their adaptation to feeding new plants they do not know.

What environmental condition contributed to the heat wave experienced in Europe and the thousands of deaths in France? a. polluted water b. sewage c. air pollution d. a and b
Answer: c. Air pollution
Explanation:
There was a heatwave in Europe during the early years of the 21st century that killed tens of thousands across the continent and thousands in France.
Air pollution was blamed for having made the situation worse because the pollutants in the air acted to prevent heat from escaping back into the atmosphere which led to increased heat on ground and therefore a heat wave.

water.
Explain what will happen to each of these two cells when they are placed into distilled water.
When plant cells are placed in salt solution their appearance is different to when they are placed in distilled water. ... Therefore, water moves out of the cell across the partially permeable membrane by osmosis and the cell becomes flaccid as the cell membrane peels away from the cell wall

Yeast undergo anaerobic respiration (fermentation), where glucose is broken down into two (2) ATP and two (2) pyruvate. This pyruvate is then used to form what waste product?
The pyruvate is then used to form Ethanol [tex][C_2H_5OH][/tex] and Carbon dioxide [tex][CO2_][/tex].
What is Anaerobic respiration?Anaerobic respiration is defined as respiration using an electron acceptor other than molecular oxygen where oxygen is not the final electron acceptor, the process still uses the respiratory electron transport chain.
Anaerobic respiration is described as the process in which there is incomplete oxidation of glucose in the absence of oxygen which is commonly known as fermentation.
One type of fermentation is alcohol fermentation where the pyruvate is decarboxylated [tex](CO_2 leaves)[/tex] to form acetaldehyde. Hydrogen atoms from NADH+. H+ are then used to help convert acetaldehyde to ethanol. NAD+ results.
Thus, the pyruvate is then used to form Ethanol [tex][C_2H_5OH][/tex] and Carbon dioxide [tex][CO2_][/tex].
