Would an amphibian that lacks lungs and breathes entirely through its skin likely be larger or smaller than an amphibian that ha

s lungs? A. Smaller because its larger surface area to volume ratio would allow it to breathe sufficiently through its skin alone. B. Larger because its smaller surface area to volume ratio would allow it to breathe sufficiently through its skin alone. C. Larger because its larger surface area to volume ratio would allow it to breathe sufficiently through its skin alone. D. Smaller because its smaller surface area to volume ratio would allow it to breathe sufficiently through its skin alone.

1. Can a single organism change its traits to become better suited for its environment during its lifetime? (highlight one) YES
Burka [1]

Answer:

check explanation

Explanation:

If you are talking about adapting to an environment then yes, like how we train to strengthen our muscles to get stronger. If you mean by evolving then no, a single organism can not evolve their traits in a lifetime, like a human can't naturally grow gills to breathe underwater

Ampicillin is an antibiotic that kills bacterial cells by disrupting the formation of cell walls. However, the pARA-R plasmid ha
Pani-rosa [81]

Answer: To eliminate bacteria that failed to take in the plasmid.

Explanation:

Research shows that plasmid DNA is only taken in by small percentage of bacteria in a large population.

Therefore, the need of growing transformed bacteria in the presence of ampicillin is very important. The main reason of this process is to kill off or eliminate bacteria that have failed to take in the plasmid, due to their possession of recombinant DNA plasmid pARA-R (an ampicillin resistance gene), that allows them to survive.

However, after completion of the aforementioned procedure, the bacteria that have been transformed will be able to take in the plasmid.

What role do photosynthesis and respiration play in the distribution of gases in seawater?
nydimaria [60]

Answer and explanation;

-The most important life processes in the oceans or sea water are photosynthesis and respiration. Photosynthesis by plants and  other lower organisms uses sunlight to convert CO2 and H2O to a carbohydrate compound; O2 is a by-product of that reaction. Respiration is the process that all organisms use to recover the chemical energy stored in organic compounds. O2 is used to oxidize organic matter and release chemical energy; CO2 and H2O are by-products.

-The rates of photosynthesis and respiration are nearly balanced.all of the organic matter produced by photosynthetic algae is respired by consumer and decomposing organisms.

construct a dichotomous key which can be used to identify the five antelopes shown in figure 1.1 use only visible features.​
Bas_tet [7]

The dichotomous key used to identify the antelopes might be based on the presence/absence of certain muscles, weight, etc.

<h3>What is a dichotomous key?</h3>

A dichotomous key is a system to classify species and/or taxonomic groups by using two different choices.

For example, the presence/absence of certain physical features can be used to identify the antelopes.

Moreover, the threshold in certain features such as weight/height can also be used to classify species.

The allele for white eyes is located at loci 12 while the allele for hairy body is located at loci 16 on one chromosome. The all
Darina [25.2K]

Answer:

white eyes and hairy body

Explanation:

Based on the scenario being described within the question it can be said that the allele combination that has the greater map distance would be white eyes and hairy body . This is mainly due to the fact that this combination have four map units between them, when compared to the other same chromosome combinations which, the next runner up would be red eyes and normal body with two-units between them.
