Answer:
(E) bu cv+
Explanation:
Linkage is the phenomena in which two genes present on same chromosome have a tendency to get inherited together.
It is given that the two autosomal genes are linked and in repulsion. This means that the dominant allele of one gene is linked to the recessive allele of another gene and vice versa.
Hence, the parental type gametes will have bu cv+ and bu+ cv combination. Since in linkage parental gametes always appear in higher numbers than recombinant gametes, out of the given options bu cv+ set of genes will be present in most gametes produced by this cockroach.
Anaerobic is the physiological process occurrence where muscle cells which amount to the gradual onset of muscle fatigue.
Fatigue muscle is the intense or repeated use of muscle which leads to the performance decline. Muscle fatigue mechanism appears in the involvement of calcium leakage. The physiological factors like maximum rate of oxygen uptake determine maximum intensity exercise.
Answer:
1. Roche limit
2. hydrogen
3. atmosphere
4. Mercury
5. Venus
6. When an object passes the Roche limit, the strength of gravity on the object increases. If the density of the planet is higher, then the object can break up farther away from the planet. If the density is lower, then the Roche limit is located closer to the planet.
7. Farther out in the solar system, beyond the frost line, hydrogen was at a low enough temperature that it could condense. This allowed hydrogen to accumulate under gravity, eventually forming the Jovian planets.
Explanation:
Chemical weathering is responsible for changing the composition of a rock
