Which statement best describes the age of the seafloor?

Biology

Fittoniya [83]3 years ago

The correct option is B. The newest crust on earth is located at the actual site of the floor spreading and as new crusts are formed they replace it. Thus, the older the crust the farther it is from the mid ocean ridge. 
Sea floor spreading is a geological process in which tectonic plates splits apart from one another. It occurs at divergent plate boundaries.

What is the conversion factor from km. to ft.? If Joe traveled 12 kilometers, how many feet did he travel?
klemol [59]
We have that <span>1 kilometer (km) of length Equals 3,280.84 feet (ft) in length</span>

If we apply a simple rule of 3

1 Km------------------3280.84 Ft

12 Km----------------- X Ft

X=12*3280.84/1

X=39370.08 Ft

<span>Joe traveled 39370.08 feet</span>

Lab report on mass and motiom golf ball, rubber ball, plastic ball
Tasya [4]

Answer:

Mass and density in the increasing order among the mentioned balls are as follows: golf>rubber>plastic whereas Motion of rubber ball is higher than of golf and plastic ball due to elasticity of the rubber.

Moment of inertia of the ball is dependent on the mass and velocity of the balls which in turn will determine the motion of the balls. Elasticity property of the rubber ball will help to provide opposite force and can enhance the motion of the rubber ball as compared to golf or plastic balls.

The illustration below shows the steps of meiosis I. What is the step that is labeled D? metaphase I metaphase II telophase II t
WITCHER [35]

The right answer is metaphase II.

The process is performed in two nuclear and cytoplasmic divisions, called first and second meiotic division or simply meiosis I and meiosis II. Both include prophase, metaphase, anaphase, and telophase. First division prophase is long and consists of 5 stages: leptotene, zygotene, pachytene, diplotene, and diakinesis. It is at this point that genetic recombination takes place at the level of chiasmus.

During meiosis I, the members of each homologous pair of chromosomes are paired during prophase, forming bivalents. During this phase, a protein structure, called synaptonemal complex form, allows recombination between homologous chromosomes. Subsequently, a large condensation of the bivalent chromosomes occurs and go to the metaphase plate during the first metaphase, resulting in the migration of n chromosomes to each of the poles during the first anaphase. This reduction division is responsible for maintaining the number of chromosomes characteristic of each species.

In meiosis II, as in mitosis, the sister chromatids comprising each chromosome are separated and distributed between the nuclei of the daughter cells. Between these two successive steps, there is no DNA replication. The maturation of the daughter cells will result in the gametes.
