- Question
Cells with similar markers stick together and function as
Options- A. Organs
- B. Tissues
- C. Systems
- D. Organisms
- Correct Answer
- Tissues
ExplanationA tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function.
Hence, Cells with similar markers stick together and function as tissues.

Correct Answer: common fibular and tibial
Explanation:
The sciatic nerve is a combination of common fibular and tibial.
The sciatic nerve divides into its two branches::
1. The tibial nerve
2. The common fibular nerve
at the popliteal fossa.
The tibial nerve, which travels down the posterior compartment of the leg into the foot.
The common peroneal nerve also called the common fibular nerve, which travels down the anterior and lateral compartments of the leg into the foot.
Correct Answer: transcription
Explanation:
Protein synthesis at the ribosome is immediately preceeded by the transcription process.
Correct Answer: FALSE
Explanation:
DNA is made of nucleotides. And these Nucleotides are made of a pentose sugar deoxyribose, a phosphate, and a nitrogen-containing bases.
Hence, the given statement 'Nucleotides are made of a pentose only' is FALSE.
Correct Answer: Mitochondria
Explanation:
Cellular respiration is the multi-step process that creates energy from nutrients and food molecules. It begins in the cytoplasm of the cell, with the mitochondria functioning as the main organelle where the rest of the process continues and finishes.
During respiration, glycolysis occurs in the cytoplasm of the cell.
Correct Answer: synthesis of DNA from an RNA template
Explanation:
A reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template by a process called Reverse Transcription.
In brief its function is that copies all or part of the virus RNA (retroviruses are RNA-only) as DNA which can then be integrated into the DNA of the host organism.
Correct Answer: All of the above
Explanation:
Single selled organisms are also known as Unicellular organisms in which they have only one cell.
Examples are :: Fungi, Algae, Amaeba, Paramaecium,...
Hence, all the above given options are single selled organisms.
Correct Answer: Replication
Explanation:
The process of copying dna is called Replication.
Correct Answer: Antidepressants work by stopping the breakdown of norepinephrine, dopamine, and serotonin They're more difficult for people to take than most other antidepressants because they interact with prescription drugs, nonprescription drugs, and some foods
Correct Answer: Stomach
Explanation:
Three main enzymes, pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids.
Hence, digestion of protein begin in stomach.
Correct Answer: The ureters are capable of peristalsis like that of the gastrointestinal tract.
