Answer:A) seafloor spreading

Explanation:

According to the theory of Harry Hess, seafloor spreading hypothesis is described as formation of oceanic crust at sides of submarines zones and ridges of mountains and then tends to spread away from that surface.

Other options are incorrect because tectonic plate movement,sediment deposition measure and global climate variation is not expressed through theory of Harry Hess.Thus, the correct option is option(A).

Answer:

R = 16mm/y

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)

R = d/t

To calculate it in millimeters per year we need to convert it:

1 km = 1000 m

1 m = 100 cm

1cm = 10mm

1 km = 1,000,000 mm

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y

Which best describes the factors that affect a phenotype? A. Phenotype is only controlled by the genotype. B. The phenotype is d

Luba_88 [7]

Answer:

D. The genotype and the environment both affect phenotype.

Explanation:

Phenotype is the outward expression or make up of an organism. The phenotype is simple the physical outlook of an organism. It is as a result of the combination of two major factors which are the genetic make up(genotype) and the environment. When both combines, an organism's pheontype is built and produced.

If the environment is lacking, a gene might not successfully express itself in an organism. Also, an organism might have the right environment but the gene is lacking.
