what is it called when an environmental factor changes the shape of an enzyme so that it no longer works to catalyze a reaction? a) killing the enzyme b) lowering the activation energy c) induced fit d) denaturing the enzyme
Answer:
c) infused fit
is correct option ...
Answer:
[tex]\boxed {\tt D. \ Denaturing \ the \ enzyme }[/tex]
Explanation:
Enzymes are special proteins that speed up chemical reactions. They have specific shapes that correlate to their functions. They also have optimal temperature and pH ranges. They should be in the range for the best results.
If an enzyme is placed in an extreme temperature or pH, the enzyme will become denatured. The enzyme will fold in a different way and its unique shape will be altered. As a result, the enzyme will slow down or stop working.
Therefore, the correct answer is D. denaturing the enzyme.

Which statement provides the best explanation for the difference in biomass of organisms found at each trophic level?
A. Organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels.
B. Organisms at higher trophic levels require smaller habitats than organisms at lower trophic levels.
c. Organisms at lower trophic levels provide less energy than organisms at higher trophic levels.
D. Organisms at lower trophic levels outcompete organisms at higher trophic levels.
Answer:A
Explanation:
The statement provides the best explanation for the difference in biomass of organisms found at each trophic level is: organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels.
WHAT IS TROPHIC LEVEL:Trophic level of an organism refers to the position of the organism in the flow of energy in an ecosystem. Organisms feed on one another in an ecosystem to obtain energy needed for their metabolic activities. More energy is contained in lower trophic levels than that of higher trophic levels. This means that, according to this question, more energy is in the producers than tertiary consumers.Therefore, the statement provides the best explanation for the difference in biomass of organisms found at each trophic level is: organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels.

What biome receives the least rainfall
Answer:
deserts
Desert biomes are the driest of all the biomes. In fact, the most important characteristic of a desert is that it receives very little rainfall. Most deserts receive less than 300 mm a year compared to rainforests, which receive over 2,000 mm.

Who were the earliest Astronomers
Answer:
The Ancient Greeks developed astronomy, which they treated as a branch of mathematics, to a highly sophisticated level. The first geometrical, three-dimensional models to explain the apparent motion of the planets were developed in the 4th century BC by Eudoxus of Cnidus and Callippus of Cyzicus.

5. If a galaxy is moving away from us, what would happen to the wavelengths of light that we see? How
would that change what we see?
The visible light spectrum. Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. ... When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer.
How do your interactions
with nonliving systems affect your
environment?
Explanation:
Interactions between different organisms are numerous and are usually described according to their positive (beneficial), negative or neutral effect on others.
The interactions between living things and their non living environment makes up a total ecosystem; understanding any one part of it requires knowledge of how that part interacts with the others. Ecosystems do not ‘collapse’ but do change in function, structure and composition over time due to natural or human disturbance (examples include the impact of drought, flooding, mowing and herbicides).
3. Which people require knowledge of Earth science and chemistry in order to do their job? astronauts O chefs O artists O sound technicians

A focus of environmental science not studied in ecology is the
Answer:
The influence of human activities on the environment
Explanation:
Anthropogenic activities may have negative effects on the environment by declining its biodiversity and by reducing natural resources. Human activities affect the environment through the use of fossil fuels (greenhouse gases), by contributing to the pollution of extensive areas, by overpopulation, eutrophication, deforestation, etc. The most significant effects of anthropogenic activities include the loss of biodiversity, climate change (global warming), habitat fragmentation, environmental degradation (e.g., ocean acidification), the introduction of invasive species, species extinction, etc.
Answer:
Ecology is the study of all organisms in an environment
Environmental science is the study of the interrelatedness of everything in that environment

Which of the following statements regarding restriction enzymes is NOT true?
A) Most restriction enzymes recognize sequences of 20-25 bp in length.
B) Bacteria can add methyl groups to their DNA to prevent digestion by endogenous restriction enzymes.
C) Most restriction enzymes recognize palindromic sequences in host DNA.
D) Restriction enzymes may produce either sticky or blunt ends when digesting host DNA.
Answer:
The correct option is option A
Explanation:
Restriction enzymes are endocleases that cleave DNA fragment (of usually four, five or six nucleotide long) at specific sites to produce blunt or sticky ends. They recognize palindromic sequences of host DNA when cleaving the specific sites. The sequences below (on complementary strands) give an example of a palindromic sequences.
5'-CCC║GGG-3'
3'-GGG║CCC-5'
As can be seen above, when read from 5' to 3', the two sequences are the same despite being on opposing strands. And when cut between the guanine (G) and cytosine (C) (as shown above), it produces a blunt end. But when cut as shown below produces a sticky end.
5'- G║AATTC -3'
3'- CTTAA║G -5'
The explanation above shows options C and D are right while option A is wrong (hence the correct option).
Also, bacteria prevent their own DNA from been digested by restriction enzymes by adding methyl group to their restriction sites which prevents restriction enzymes from recognizing restriction sites of their DNA; this generally makes bacterial DNA to be highly methylated. This explanation makes option B right also.
What is the composition of hair?
Answer:
The hair is made up of 95% keratin, a fibrous, helicoidal protein (shaped like a helix) that forms part of the skin and all its appendages (body hair, nails, etc.). Keratin is synthesized by keratinocytes and is insoluble in water, thus ensuring impermeability and protection for the hair.
Explanation:
Autism is a neurological disorder thought to be caused by mutant alleles of one or more genes. Scientists had been wondering why the number of children diagnosed as autistic increased dramatically in a decade, from 1 in 500 in 2002 to 1 in 88 in 2012. Researchers now think that they might have found at least part of the answer: Men are fathering children at later and later ages. A paper published in the journal Nature in 2012 showed a correlation between paternal age and the incidence of autism; the age of the mother was not a factor. How does this observation provide a possible explanation for the apparent increase in the rate of autism?
Answer:
There is an accumulation of genetic mutations in the DNA of sperms due to its constant mitosis.
Explanation:
The germinative cells that will become sperms are under constant mitosis. During this process, DNA mutations can happen and be transmitted from one generation of cells to the other as the years go by, and more cell divisions take place, more mutations the DNA in the sperm will have. When the number of mutations reaches a certain level, his child will express these mutations and have autism.
The egg of the mother is not a factor because the germinative cells in women are not under constant mitosis, so there is not an accumulation of gene mutations. Women are born with an exact number of eggs for all their life.
