Answer:

Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.

The study and record of fossils as done by planetologists has evolved greatly... from using hands to dig up bones and other fossil types to the use of machinery and from guessing possible ages of those fossils to the use of technology for more accurate data and results.

Nitrogen fixation, the process of making nitrogen usable for living things, happen most in

Nady [450]

Answer:

The nitrogen gas must be changed to a form called nitrates, which plants can absorb through their roots. The process of changing nitrogen gas to nitrates is called nitrogen fixation. It is carried out by nitrogen-fixing bacteria. The bacteria live in soil and roots of legumes, such as peas.

When godfrey hardy and wilhelm weinberg described the factors that affect genetic equilibrium, they first had to define what it

Vitek1552 [10]

Answer - A. Mating Must occur randomly

Reasoning - Since mating must occur randomly are helps with the balance or equilibrium in genetic without any changes within that population since we do not want genetic drift, mutation and especially do not want any foreign or different species mating with the species we are targeting. So A is your best answer.

You perform a co-transduction experiment with pro+ gal+ arg- man- donor and pro- gal- arg+ man+ recipient. On master plate 1, yo

vladimir2022 [97]

Answer:

arg---pro---gal---man.

Explanation:

The co transduction frequency is directly proportional to the distance between two genes.

The recombination frequency can be calculated as follows;

A - B = (A - B / A ) x 100

Here, A and B represent the different genes.

For plate 1 :

Pro- gal = A - B = (1000 - 400/1000) x 100 = 60% . Here, A is Pro and B is gal.

Pro - Arg = A - C = (1000- 290/1000) x 100 = 71% . Here, C is Arg.

Pro - Man = A - D = (1000-1000/1000) x 100 = 0%. Here D is Man.

For Gal transductants of plate 2

Gal - Pro = A - B = (1000 - 390/1000) x 100 = 61% . Here A is Gal and B is Pro.

Gal - Arg = A - C = (1000- 289/1000) x 100 = 71% . Here, C is Arg.

Gal - Man = A - D = (1000-900/1000) x 100 = 10%. Here D is Man.

From the recombination frequencies it is clear that the location of genes are in the order of

Thus, the correct answer is option (B).

What is most helpful in increasing the rate of plastics recycling

sleet_krkn [62]

It makes sense that increasing the rate of plastics recycling is helpful for eliminating waste. Think about it, when something can be reused, then it should be. Recycling allows this to happen and prevents landfills from being filled too quickly.
