Mollusks and arthropods can detect stimuli from their environment, while jellyfish and sponges cannot.
B.
Mollusks and arthropods exhibit cephalization, while jellyfish and sponges do not.
C.
Mollusks and arthropods exhibit segmentation, while jellyfish and sponges do not.

The correct answer is option D

The model organisms is a species that researchers use to understand certain biological features. These species are arthropods and Mollusks tend to respond to environment better as compared to the jellyfish and sponges.

Jelly fish and sponges lack nervous system and they do not respond to the stimuli generated by the environment.

A rheumatologist specializes in diagnosing and treating diseases and disorders involving the bones, joints, and muscles.
Lera25 [3.4K]

Answer:

False.

It is not true that a rheumatologist specializes in diagnosing and treating diseases and disorders involving the bones, joints, and muscles.

Explanation:

  • A rheumatologist is a doctor who examines the internal medicine of patients in case of treating inflammatory conditions.
  • The rheumatologist treats and diagnoses the patients with problems related to different aspect that affects the joints, tendons, ligaments, bones, and muscles.
  • It is a basic fact that rheumatologist do not perform any surgery instead they treat musculoskeletal conditions.
  • So they do not treat any disorders of bones or joints but they diagnose the inflammatory conditions affecting the bones and joints.

What should be done to correct positioning on an anteroposterior (AP) elbow with lateral rotation, when the radial head is sligh
natka813 [3]
<h2>Functions of elbow joint </h2>

Explanation:

  • The elbow joint should be rotated laterally.
  • This is because the elbow is basically a pivoted joint, however, it has the extraordinary capacity to turn the distal arm in pronation and supination
  • These exceptional movements, alongside a wide scope of dynamic exertional powers, incline the elbow and its structures to critical wounds, especially with tedious movements
  • Understanding the life systems and the physical powers of development will help in diagnosis
  • Hence, the right answer is "elbow joint should be rotated laterally on an (AP), when the radial head is slightly superimposed over the proximal ulna on the first effort"

During conjugation, one gene (A) is found to transfer to the recipient bacteria 26 minutes following the start of conjugation, w
AnnyKZ [126]

Answer:

a. All of the answers are correct.

Explanation:

During conjugation a bacteria transfers it's genetic material to another bacteria. The genetic material has genes in a particular order so we can easily know the order of the genes through experimentation. The transfer of genes occurs as per the time allowed. If two genes are nearby then they will be transferred one after the other.

For example in the given question, gene A was transferred to recipient bacteria in 26 minutes, gene M was transferred in 37 minutes while gene T was transferred in 45 minutes, it simply means that the order of genes is A M T. Gene M was transferred to another bacteria after A was transferred because time required to transfer it is 37 minutes which is less than time required to transfer A which is 26 minutes. Gene T took maximum time to get transferred so it will be last to be transferred.

After calculation, we can easily infer that the genetic distance between A and M is 11 minutes (37 minutes - 26 minutes = 11 minutes). Similarly we can get genetic distance between A and T as 19 minutes and between M and T as 8 minutes. So all the given options are correct.
