The correct order of events during meiosis is:
prophase I,
metaphase I,
anaphase I,
telophase I,
cytokinesis, and
meiosis II.
In DNA, adjacent nucleotides are linked by a phosphodiester bond: a covalent bond is formed between the 5' phosphate group of one nucleotide and the 3'-OH group of another.
Hence, in this manner, each strand of DNA has a "backbone" of phosphate-sugar-phosphate-sugar-phosphate.
Glycolysis is the first step of cellular respiration. This process breaks down glucose into two pyruvic acids, and produces 2 ATP and 2 NADH.
In eukaryotic cells, glycolysis and fermentation reactions occur in the cytoplasm.
The small intestine is the main area of the GI tract for absorption.
The small intestine has three separate sections. Theyare :
1. The duodenum
2. Jejunum and
3. Ileum.
Hence, the majority of nutrient absorption occurs in the duodenum and jejunum of small intestine.
Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). During translation, an mRNA sequence is read using the genetic code, which is a set of rules that defines how an mRNA sequence is to be translated into the 20-letter code of amino acids, which are the building blocks of proteins.
In short, during the process of translation source language text is conveyed to destination language.
A tertiary consumer is an animal that obtains its nutrition by eating primary consumers and secondary consumers.
Usually tertiary consumers are carnivorous predators, although they may also be omnivores, which are animals that feed on both meat and plant material.
Tertiary consumers often occupy the top trophic level, and so are predated by no other animals; in this case they are called "apex predators". However, when they die their bodies will be consumed by scavengers and decomposers.
Spongy, porous bone tissue is also called cancellous bone.
Cancellous bone is found in bones that aren't generally under significant stress like in the shoulder blades, ribs, parts of the skull, and at the ends of long bones.
Emphysema is a condition that involves damage to the walls of the air sacs (alveoli) of the lung i.e, primarily causes shortness of breath due to over-inflation of the alveoli.
First, emphysema causes holes to gradually form inside the lungs' air sacs, thereby weakening their internal structure and inhibiting the exchange of oxygen and carbon dioxide.
The given statement that all cells divide at the same rate is FALSE.
No, all cells do not divide at the same rate. Cells that require frequent replenishing, such as skin or intestinal cells, may only take roughly twelve hours to complete a cell cycle. Other cells, such as liver cells, remain in a resting state (interphase) for up to a year before undergoing division.
