During the early days of deciphering the human genome, scientists were surprised to find that the number of genes appeared to be
Alekssandra [29.7K]

Given what we know, we can confirm that the aspect of nucleic acids and transcription that can help explain this discrepancy is that of alternative splicing.

<h3>Alternative Splicing.</h3>
  • This process allowed the cells to use a single gene for the creation of various proteins.
  • This process includes the separation of RNA at splicing sites to create new versions of the mRNA strand.
  • This helps to increase the diversity of mRNA's available and create more proteins.

Therefore, given that alternative splicing allows the cells to create multiple forms of distinct proteins from a single gene, this allowed our organisms to develop the vast number of proteins we use, without the need for a much larger genome.

Name three social benefits provided by biodiversity.
damaskus [11]

There are many benefits provided by biodiversity. It can be in our biological resources, ecosystem services and also social benefits. The three social benefits provided by biodiversity would be the following:

1. Research, education and monitoring 

2. Recreation & tourism 

3. Cultural values 

Explanation:

Biodiversity is “the variability among existing animals from all causes including temporal, marine and other aquatic ecosystems, and the environmental complex.

Pollinators, including bees and butterflies, contribute meaningful environmental and economic advantages to agricultural and essential ecosystems, including adding heterogeneity and productivity to food crops. As many as one-third of the world's food production relies directly or indirectly on insect pollination.

seeds that are planted upside down are still able to grow into mature plants which explanation best explains this phenomenon?​
pav-90 [236]

Answer:

This question is incomplete but the completed question is below

eeds that are planted upside down are still able to grow into mature plants. Which explanation best explains this phenomenon?

(a)The roots change into branches, and the branches turn into roots.

(b)The roots grow toward the force of gravity, and the shoots grow away.

(c)The plant will become a smaller version of a mature plant.

(d)Roots always grow toward the dark, and shoots grow toward the light.

Two options appear to be correct here: options B and D

Explanation:

Regardless of the direction the seed is planted, the seed has the ability to re-position itself via the help of growth hormones that respond to gravity and redirect the seed into the proper orientation. However, after re-orientation of the seed, the root grows toward the direction of gravity (a process known as gravitropism) while the shoot grows toward the direction of sunlight (a process known as phototropism). Even though two options appear to be correct here, the most correct option based on he question is b
