The above is not an example of sexual selection because sexual selection is about differential success in acquiring males.In sexual selection one biological sex chose mates of other sex to mate with. and compete with members of the same sex for access of members of opposite sex
I would say C. Remember, in anaphase the spindle fibers pull the chromatids apart. If it were meiosis then chromosomes would be separating (homologous chromosomes.) Hope I helped :)
Explanation:
where is the option of the Question first u have to give me options so I can do it for u☺☺
<u>Answer</u>:
The enzyme activity decreases due to the denaturation of the enzymes.
<u>Explanation</u>:
Enzymes are built with proteins. Enzymes catalyze a reaction by binding to the substrate molecule in its active site. As temperature increases the rate of the enzyme activity increases because kinetic energy of the molecules get increases.
But when the temperature crosses approximately 37-40 degrees Celsius the structure of enzyme denatures due to breakage of its intra- and intermolecular bonds. The active parts of an enzyme changes and it can no longer bind to its substrate hence the enzyme activity decreases.
Answer:
The correct match is given below:
Explanation:
- The condition of having gametes similar in shape, but different in size – anisogametes.
- The condition of having anisogametes - anisogamy
- The part of the stamen of a flower that bears the pollen – anther
- An organ in simpler plants that produces sperm cells – antheridium
- An organ in lower vascular plants, gymnosperms, mosses, and liverworts which produces an egg cell - archegonium
- A reproductive organ of gymnosperms having a central axis with radiate scales and bracts; can either produce pollen or ovules – cone
- An act of fertilization involving the transfer of cell contents to another cell; usually occurs in simpler organisms – conjugation
- A large gamete with stored food - Egg
- A long, whip-like structure extending from a cell used for locomotion- Flagellum
- An organ of lower plants, some protists and some fungi that produces gametes - gametangium
- Gamete producing organs in animals – gonads
- Cone-bearing plant; often called evergreen – Gymnospers
- Incapable of independent movement - immotile
- Gametes that are the same in size and shape - isogametes
- Capable of independent movement- motile
