Answer:
The best description of the events occurring during Ana-phase I of meiosis:
c. Homologous chromosomes randomly separate and migrate to opposite poles.
Explanation:
Meiosis:
It is such type of cell division that occur in animals, plants resulting in four daughter cells and each of daughter cell have the half number of chromosomes from the parent cell.
- Anaphase is one of important phases of meiosis. The option a is incorrect as chromosomes go randomly to opposite poles.
- The option b is incorrect as all of chromosomes inherited from mother and father goes randomly to opposite poles.
- The option c is correct as it is the true description of anaphase I of meiosis.
- The option d is incorrect as the sister chromatids don't separate rather they remain joined.
16 neutrons are present in the most abundant isotope.
Explanation:
Phosphorus has 18 isotopes. The most common isotope has mass number (no. of protons 15+ no. of neutrons 16=) 31 .
C.) Scanning electron microscope. You would not be able to see a whole insect with one of these.
Hope this helped :)
Answer:
Nodes
Explanation:
A node is a stem zone where the leaves are attached, the stem portion between nodes are called internodes, the thricomes are like little hairs in the leave and the lenticels are spaces in the leave that helps to transpiration like the stomata.
So, the stem regions at which leaves are attached are called nodes.
Also the name nodes is really common in gardening, it helps a lot to identify which leave are they talking about.
Answer:
Explanation:
One of the functions of the muscle is the storage of amino acids which can be used for energy production when demands are high or for protein synthesis. But during muscle atrophy, this function becomes reduced which could lead to the particularly muscle been unable to stretch or contract due to weakness, it could also lead to the imbalance between protein synthesis and degradation.
