The correct answer to this open question is the following.

Although there are no options attached we can say the following.

The correct answer is the Cambrian period.

By the end of the Cambrian period, all major animal lineages were present in the seas due to the great adaptive radiation of animals.

We are talking about 500 to 540 million years ago on planet Earth.

Scientists consider that during the Cambrian period, major groups of animals diversified. Marine animals such as trilobites were among the first fossils discovered by scientists. Oxford curator Edward Luhyd started to study these fossils in 1668.

In a population of pea plants, green peas are the result of a homozygous recessive condition. If the frequency of the allele for

kompoz [17]

Answer:

32%

Explanation:

Since the population is in Hardy-Weinberg equilibrium, the allele and genotype frequencies will remain constant over generations.

The frequency of the recessive allele (q)= 0.20

Since p+q= 1

so, p= 1-q

and p=1-0.20= 0.80

The frequency of heterozygous genotype (2pq) = 2 x 0.20 x 0.80 = 0.32 or 32%

Therefore, the expected frequency of heterozygous genotype in the next generation would be 32%.

Trees provide socio-economic benefits by creating a friendly environment that lures more customers to the shopping areas they are found.

Trees are very important to our environment for the following reasons:

They release oxygen during photosynthesis, thereby producing oxygen for humans
Trees take in carbon dioxide during photosynthesis, thereby purifying the atmosphere and limiting greenhouse effect.
They also beautify the environment
Trees serve as shades for humans

All these importance of trees is what will definitely lure people to go to shopping areas that have trees planted in them.

This means that, trees boost sales of businesses wherever they are planted. In this way, we can state that because trees create a friendly environment, people are lured where trees are and they spend more money there, and so therefore, it serves as social or economic benefit.
