Over the years, bacteria have become less sensitive to antibiotics used for medicinal and sanitation purposes. This lack of sensitivity is termed antibiotic resistance. How is antibiotic resistance an adaptation?
A.
Antibiotic resistance has caused antibiotics to become more specialized, thus adapting the antibiotics to particular bacteria species.
B.
The trait giving bacteria antibiotic resistance has reproductively isolated groups of bacteria.
C.
The trait giving bacteria antibiotic resistance has become common, giving bacteria with the trait a selective advantage.
D.
Antibiotic resistance makes it more difficult for bacteria to infect hosts, thus is a selective advantage for the host.

to allow movement of the tendons within the carpal tunnel zone, each tendon is encased in a __________.
To allow movement of the tendons within the carpal tunnel zone, each tendon is encased in a sheath.
The sheath is a fibrous but at the same time serous element that is composed of a viscous liquid called the synovium, which is designed in order to allow the tendons to move with the bones.
The function of the sheaths is to allow a correct sliding between the tendon where it meets the bone through which it passes.
The importance of sheaths for the biomechanics of movements is that if they were not located in the tendons, these tissues would wear out very easily, thus causing injuries such as tenosynovitis.
The best known synovial sheaths are those of the flexor apparatus of the hand, that is to say to the internal and external digitocarpal, in the fibrous band of the foot, and in the long tendon of the biceps muscle.
Therefore, we can conclude that to allow movement of the tendons within the carpal tunnel zone, each tendon is encased in a sheath.

If a recessive trait is beneficial to an animal, what happens to the trait's proportion in the population?
It becomes more common
It becomes less common
It doesn't change much
Answer:
It becomes more common
Explanation:
Even if the trait is recessive if it is beneficial to a population then it will become more common because those with the trait are more likely to survive. For example, if a population of beetles lives on green grass and the dominant trait is for the beetles to be black and the recessive trait is green then the green ones will survive because the black beetles will be eaten first.

In chloroplasts, when the two photosystems work in series, electrons ejected from the photosystems do not return to them, which is known as ______. Multiple choice question. oxygenic photophosphorylation cyclic photophosphorylation noncyclic photophosphorylation NADPH based photophosphorylation
When electrons do not return to the photosystems, it is because of a process known as oxygenic photophosphorylation, a process that is key to photosynthesis.
Photosynthesis is the process by which plants get their energy. This process involves many steps taken in order to turn energy from light, into sugar and molecular energy known as ATP, needed for plants to survive. This process uses a variety of important and complex steps, among which is included oxygenic photophosphorylation.
Oxygenic photophosphorylation is one of the key processes to photosynthesis. It involves the use of photosystems one and three, located in the thylakoid membrane of plant cells, in order to produce NADPH and ATP. These systems enter a state of photoactivation, releasing an electron to be carried by the NADPH molecule towards the Calvin cycle where the electron can be placed onto a carbon atom, for long-term storage, often as a carbohydrate.

what is the primary pigment that makes leaves green in land plants?
Chlorophyll is the primary pigment that makes leaves green in land plants, by absorbing red and blue light.
What is chlorophyll?It is a pigment present in the plant leaves, through which plant leaves apers green in observation, it plays several roles in the plants other than the green appearance of the leaves.
During photosynthesis, this chlorophyll pigment is responsible to form reaction center through which light is absorbed and leads to a process through which light converts into chemical energy for the synthesis of food.
It is present in the chloroplast, which is the site of photosynthesis, and provides the necessary components for plant food synthesis.
Therefore, the primary pigment that makes leaves green in land plants is known as chlorophyll.

what is a major difference between messenger rna molecules and transfer rna molecules?
Answer:
1) Messenger RNA molecules contain ribose, and transfer RNA molecules contain deoxyribose.
2) Messenger RNA molecules function in carrying coded information to the ribosomes, and transfer RNA molecules function in carrying amino acids to the ribosomes.
The major difference between messenger RNA molecules and transfer RNA molecules is that messenger RNA carries the genetic information, while tRNA carries the amino acids.
What is RNA?RNA is ribonucleic acid. In the cell, different types of RNA are found, such as mRNA (messenger RNA), tRNA (transfer RNA), rRNA (ribosome RNA), SnRNA, miRNA, etc. mRNA, or messenger RNA, is formed from DNA. It carries the information of a cell. The three consecutive nucleotides of mRNA make up a codon. An example of a codon is AUG.
tRNA has a cloverleaf-like structure. It has different domains such as the TΨC loop, the DHU loop, the anticodon region, and at the 3' end it is attached to an amino acid. The anticodon of the tRNA reads the codon sequence of the mRNA and attaches the amino acids. For the AUG codon methionine is attached.
Hence, the main difference between the messenger RNA and transfer RNA molecules is that mRNA carries the message of the genetic material, while tRNA carries amino acids to express the genetic material on mRNA.

the chemiosmotic hypothesis states that the energy for the production of atp during photosynthesis comes from
The chemiosmotic hypothesis states that the energy for the production of ATP during photosynthesis comes from the Mitochondria.
The mitochondria is regarded as very important and the power(energy) house of the cell as a lot of ATP synthesis activities takes place in this organelle.
The hypothesis was used to prove that most of the ATP production that takes place in respiring cells comes from the electrochemical gradient present across the inner membranes of mitochondria.
ATP is formed from the break down of the molecules rich in energy such as glucose and the use of energy of NADH and FADH₂ which are formed from its breakdown.
