Answer:
The correct answer is option A.
Explanation:
Striated muscle tissues are muscle tissue that made up of repeated long functional units known as sarcomeres. The long bands of sarcomeres along with muscle fibers provide it a striated appearance. Striated muscles have more mitochondria in it and also contain cells that are multinucleated, unlike smooth muscles. The major function of these muscles is to generate force and contract. Heart and respiratory organs have such muscle.
Thus, the correct answer is option A.
Answer:
The correct answer would be C, abdominal.
Explanation:
This is true because the pelvic cavity is protected by the pelvis, the cranial cavity is protected by the skull, the spinal cavity is protected by the skull as well as the vertebral column, and the thoracic cavity is protected by the rib cage. Leaving the abdomen the only body cavity not being protected by some sort of bone.
I hope this helps! :)
Answer: option D) It produces four genetically identical gametes.
Explanation:
Meiosis DOES NOT produces four (4) genetically identical gametes RATHER four (4) offspring cells that are genetically DISSIMILAR with half of the parent chromosome, due to the exchange of material that occurs between homologous chromosomes during crossing over (a distinguishing feature of meiosis).
This exchange is the basis for variation that is observed among offsprings.
So, all options are true except option D
Answer: & Explanation:
The overall for equation for gluconeogenesis is
2 Pyruvate + 4 ATP + 2 GTP + 2 NADH+ + 2 H+ + 4 H2O → 1 Glucose + 4 ADP + 2 GDP + 6 Pi + 2 NAD+
From the equation
2 molecules of pyruvate is needed to generate one molecule of glucose.
No NADH is produced, but 2 molecules of NADH are used during the glyceraldehyde-3-phosphate dehydrogenase reaction in glycolysis.
No ATP is produced, but 4 molecules of ATP are used to generate one molecule of glucose. During the carboxylation of pyruvate to oxaloacetate in the mitochondria by pyruvate carboxylase one ATP is required for each pyruvate molecule. Also during the phosphorylation of 3-phospho glycerate to 1,3- Bisphospho glycerate, 1 ATP is required for each molecule.
6 Pi are produced in the generation of a molecule of glucose.
