Answer: Stratigraphy and Biostratigraphy
Relative dating is a method of determination of age, in which one object or organism is compared with the other object or organism found in the heap of strata. It is a method for determining the relative order of the past events, without stating the absolute age.
Stratigraphy is a branch of geology that studies the relative position of the sediments and rocks in the strata with respect to the geological timescale. Biostratigraphy is the branch of stratigraphy which deals with the relative aging of fossils with respect to the strata in which these are found defining a particular period of geological time scale.
Answer:
Matter
Explanation:
Everything in our world is made of matter.
Answer:
Yes, <em>the random alignment of the tetrads along with the equatorial plate occurs during metaphase I.</em>
Explanation:
After the crossing-over in prophase I, and during metaphase I, fibers of the <em>spindle apparatus</em> capture chromosomes and <em>take them toward the center of the cell, to the </em><u><em>metaphase plate.</em></u><em> </em>The homologous pairs of chromosomes get aligned in the metaphase plate for their posterior separation in <u>anaphase I.</u>
<em>Each chromosome of the pair joins with a microtubule of only one of the spindle poles</em>, so the two equivalent chromosomes join the fibers of opposites poles.
When they align in the center of the cell, their orientation is random.
Thanks to what we know about muscles and the fibers they contain, we can confirm that the statement in the question is in fact true.
Muscle is a type of tissue which due to coordinated systems that make up their composition, have the ability to contract. This ability allows for greater efficiency. In humans, the muscle systems are classified into three kinds:
- Cardiac muscle
- Skeletal muscle
- Smooth muscle
Despite the different classifications and functions of each muscle type, each of these muscles contains a combination of three types of muscle fibers, which are the fibers listed in the question:
- Slow oxidative
- Fast oxidative
- Fast glycolytic.
