Answer:

a) snRNA

Explanation:

The association of small nuclear RNA  (snRNA) and some specific proteins forms small nuclear ribonucleoprotein complexes.  Some complexes are spliceosomes,  molecular machines -made up of a snRNA and about 80 proteins- that remove introns from pre-mRNAs via successive phosphoryl transfer reactions.

Rina8888 [55]

Answer:

Homolog genes with sequence identity often exhibit differences in length associated with size variations in the intronic sequences

Explanation:

In eukaryotic organisms, genes are composed by 1- coding sequences (i.e., exons) that are transcribed into precursor mRNAs, and 2-noncoding regions (or introns), which are not transcribed but contain sequences involved in the control of gene expression

What happens if you drop some type of liquid on a cable such as a phone charger? Can you get hurt? Can you still use it?
ipn [44]

It really just depends. If the liquid got in any crevices it might not work. If it wasn't plugged in, no you cannot get hurt. But I've had chargers that I spilled water on and they still work fine, but again, it depends. Like if there's a tear in the cord that liquid got in, then no it probably won't work anymore.

NeX [460]

Explanation:

Biodiversity refers to the diversity of biology or living organisms on Earth. The biodiversity is responsible for maintaining various biogeochemical on this planet.

The biodiversity has been drastically affected by the anthropogenic factors which has caused the deterioration of biodiversity.

The main anthropogenic factors are:

1. Habitat fragmentation: the human activities like construction of road passing through the habitat for organisms can lead to habitat fragmentation which could decrease the gene flow in the species.

2. Deforestation: the cutting of trees has led to the extinction of species.

3. Climate change : Global warming is the result of the industrial revolution initiated by humans in 19th century.

4. Exploitation of natural resources: the humans have continuously exploited human resources for their use.

5. Hunting of animals: The hunting of animals is one of the major factor for extinction of animals.

What are the structures in the leaves that are unutilized in transpiration? ( pls hurry)
navik [9.2K]

Answer:

Stomata – Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.
