Answer:
<u>Option-(C,A):</u>Archaea must undergo meiosis prior to cell division, and Each chromosome in a polyploid organism has distinct genetic information.
Explanation:
- <u> Archaea are polyploid:</u>
Archea are prehistoric organisms who can be also termed as the prokaryotic living cells, as they developed from a less developed form to a more complex shape or system. As the feature of being a polyploid makes it easy for any archea to survive in the most severe conditions. As the polyploids contain a number of genetic materials in pair, as each pair is very distinctive in features or more independent in regulating a function then the other. Giving it a more diversity of genetic sequence its genome.
Along, with that the process of meiosis occurs prior to the process or event of cell division. Which is for production of the copies of the parent cell, which posses the same genetic material as that of the parent cells.
Answer:
Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.
Explanation:
Answer:
the hormone receptor is a heterotetramer composed of two subunits with 95 kDa and two subunits with 135 kDa
Explanation:
In this case, the heterotetramer is composed of two heterodimers, each composed of two subunits that held together by disulfide bonds. These heterodimers bind together through hydrophobic interactions in order to form a tetramer. The Sodium Dodecyl Sulfate (SDS) is a denaturing detergent that dissociates both heterodimers by interfering with hydrophobic interactions that hold heterodimers together. It is for that reason that only a single band of 230 kDa is observed (135 kDa + 95 kDa = 230 kDa). Moreover, 2-Mercaptoethanol breaks disulfide bonds, thereby separating the two subunits in the heterodimer. In consequence, after the use of this chemical compound (2-Mercaptoethanol), two different bands with 135 kDa and 95 kDa can be observed.
Answer:
The correct answer is option (d)-"All of these are found in the fossil record and have been used by scientists to understand human evolution".
Explanation:
There is plenty of evidence that supports the proposal of how humans has evolved during past times. The fossil records that scientists has used understand human evolutionary patterns include the following. Ardipithecus ramidus bones that revealed advances in upright walking, even tough they had a small brain that measured between 300 and 350 cm3. Australopithecus lack of an opposable big toe suggest that they lived on the ground instead of in trees. Homo erectus was the first species to use and control fire, as suggested by evidence of microscopic traces of wood ash.
Answer:
Water and polymers.
Explanation:
Dehydration reaction may be defined as the reaction in which a water molecule is released during the process of reaction. Large molecules are joined together by the process of dehydration.
Polymers are formed by reacting the monomers together with a release of small molecules like water. Hence, water and polymers are formed by dehydration reaction.
Thus, the correct answer is option (3).
