Restriction enzymes: A) act at the membrane to restrict the passage of certain molecules into the cell. B) are highly specialized ribonucleases that degrade mRNA soon after its synthesis. C) are sequence-specific DNA endonucleases. D) are very specific proteases that cleave peptides at only certain sequences. E) catalyze the addition of a certain amino acid to a specific tRNA. c The biological role of restriction enzymes is to: A) aid recombinant DNA research. B) degrade foreign DNA that enters a bacterium. C) make bacteria resistant to antibiotics. D) restrict the damage to DNA by ultraviolet light. E) restrict the size of DNA in certain bacteria.
Answer:
C) are sequence-specific DNA endonucleases
Explanation:
Restriction enzymes represent a type enzyme capable of recognizing short nucleotide sequences to cut at specific restriction sites in the DNA, these sites are known as target DNA sequences. Some of the most commonly used restriction enzymes are EcoRI, BamHI and HindIII, isolated from Escherichia coli, Bacillus amyloliquefaciens and Haemophilus influenza, respectively. Restriction enzymes are endonucleases because these enzymes only cleave the phosphodiester bond within the DNA chain, conversely to exonucleases, which cleave nucleotides from the end of the polynucleotide DNA strand.

What impacts would suburban development have on undeveloped deciduous forest and meadow ecosystems?
Answer:
Impacts of suburban development on undeveloped deciduous forest and meadow ecosystems are - : loss of biodiversity , excessive land use , deforestation , degradation of air quality , increase in the amount of greenhouse gases , therefore leading to environmental loss .
Explanation:
SUBURBANIZATION -: Suburbanization is a demographic change, resulting in the creation of (sub)urban sprawl, from core urban areas to suburbs. Low-density, peripheral urban areas are increasing as a consequence of the migration of households and companies out of the city centers. (Urbanization, which signifies a demographic change from rural areas to urban centres, is inversely related to suburbanization.)
Within the central urban area, many residents of metropolitan regions work and prefer to live in satellite communities called suburbs and commute to work by car or mass transit. Others have taken advantage of advances in technology to operate from their homes.
Environmental Implications -: This can have negative effects on the community with the growth of suburbanization and the spread of individuals living outside the city. Suburbanization has been related to an increase in the mileage of automobiles, an increase in land usage, and an increase in the use of residential electricity. These suburbanization factors then induced air quality deterioration, increased use of natural resources such as water and oil, and increased quantities of greenhouse gases. This causes increased use of oil and gas as well as an increase in pollution as the use of cars to drive to and from the workplace grows. This will then cause air pollution and degrade the air quality of a region with a rise in emissions from vehicles. Suburbanization is increasing, leading to an increase in housing growth, which causes the consumption of land and land available to increase.
Carrie is conducting an experiment on a solution. The solution’s initial pH is 10. Then, as Carrie gradually adds Compound X into the solution, the pH decreases to 5. Which is the most likely identity of Compound X? *
Answer:
Compound X must be an acid
Explanation:
Acids have a lower pH than alkaline solutions. When you add an acid to a solution, the pH drops, as has happened here. If the pH did not change, we would assume compound X was neutral. If the pH increased, we would assume compound X was even more alkaline than pH 10.

Explain what would happen to the food chains if:
a.) A toxin was released into the local water supply, and the mice in the meadow died.
b.) There was an increase in the hawk population.
a. The hawks would die because the mice died, since the bottom part of the food chain was taken out, the whole food chain would fall apart;
b. All the mice would die; since there are more hawks to eat the mice, the mice would be eaten faster than they could reproduce, and they would slowly die out.

Fat and ATP are different molecules that can both be described as molecules that store
energy. Compare the functions of these molecules in terms of energy storage.
A) O ATP molecules are made when where there is an excess amount of energy,
while fat molecules are used immediately.
B) O ATP molecules are used for long-term storage, while fat is used for
immediate energy
C) O Fat molecules are stable and can be stored for a long time, while ATP is not.
D) O Fat molecules are unstable and can be stored short-term, while ATP
molecules are stable and stored long term.
Answer:
C) Fat molecules are stable and can be stored for a long time, while ATP is not.
Explanation:
ATP is short-term energy, and fat is long-term energy and is used when when there is no more energy. Fat molecules are also highly stable because of the many covalent bonds
Answer:
C, i think
Explanation:
ATP is short term storage due to the fact that it is produced rapidly and used up just as fast in cells. Fat is long term, usually when there is no energy, fat is burnt up (during exercise is the most common) and used for energy
Explain how we know organisms evolved, beginning with how complex molecules were first created. At which point must science speculate about how life began? Why is that? Do you think we will ever figure out the missing clues?
Answer:
Untangling the origins of organisms will require experiments at the tiniest ... as scientists are hoping to discover, the path to it cannot be so hard. ... To understand how life might begin, we first have to figure out ... Some scientists think that life originally used simpler molecules and only later evolved RNA.

Why must dioecious organisms find mates in order to reproduce?
Answer:
Most familiar is biparental reproduction (sometimes called dioecious reproduction). ... Dioecious reproduction leaves the greatest genetic variability among offspring (an advantage under changing conditions or in competition or when faced with disease), but the organisms must find mates.
Most of the dioecious organisms find mates in order to reproduce because they are unisexual in nature and they always need a partner to reproduce.
What are the two types of reproduction ?The two types of reproduction are sexual and It is the mating between two partner that happens in the case of sexual reproduction. In the case of asexual it is the single parent giving rise to its younger ones.
In the case of dioecious animals that is the organisms bearing either of males or either of females and in this case it is hard for organisms to give birth to their younger ones individually.
dioecious animals need to find the partners as per the compatibility and the specificity. The individuals with the compatibility and the specific orientations give rise to their younger ones and this process is called as reproduction.
