Answer:

1.Oceanic crust is constantly formed at mid-ocean ridges, where tectonic plates are tearing apart from each other.The age and density of oceanic crust increases with distance from mid-ocean ridges. Just as oceanic crust is formed at mid-ocean ridges, it is destroyed in subduction zones.

2.The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.

3.A place's absolute location is its exact place on Earth, often given in terms of latitude and longitude. For example, the Empire State Building is located at 40.7 degrees north (latitude), 74 degrees west (longitude). It sits at the intersection of 33rd Street and Fifth Avenue in New York City, New York.

I need help with the image (phenotypes and genotypes).

Flauer [41]

Answer:

See the answer below

Explanation:

1. Only one phenotype is present in the F1 generation offspring. Since tallness was dominant over shortness, all the offspring in the F1 generation appeared tall.

2. Two phenotypes are present in the F2 generation - 9 tall and 3 short. The short trait reappeared at the F2 generation.

3. The genotype of the F1 offspring would be heterozygous. Assuming the purebred tall is AA and the purebred short is aa:

AA x aa

Aa Aa Aa Aa

All the F1 offspring will appear tall and their genotypes would be heterozygous.

4. Assuming that the allele for height is denoted with A (a), the genotype of the purebred tall plant would be AA.

5. In a similia vein, the genotype of the purebred short plant would be aa.

Skeletal muscle fibers are classified as ""fast"" or ""slow"" based upon what factor?

andrey2020 [161]

Answer:

Skeletal muscles fibre are classified base on how the produce energy.

Explanation:

Skeletal muscles fibres consist of bundles of cells that form muscles which contain myobrills.

Skeletal muscles are classified based on how the produce energy;

Type 1 or slow pitch muscle fibres are more efficient and last for a long period of time. They are use for postural maintenance or endurance. It use aerobic respiration to produce energy or ATP.

Type 11 or fast twitch muscle fibres use anaerobic respiration and are for short speed and fatigue more easily than type 1.
