What is the job of tRNA
exis [7]

Answer:

To make our mRNA

Explanation:

I think it is this one, but I am not sure, sorry if it is wrong. :(  

But I do know this, I think it might help you:

A transfer RNA (tRNA) is a special kind of RNA molecule. Its job is to match an mRNA codon with the amino acid it codes for. You can think of it as a kind of molecular "bridge" between the two. Each tRNA contains a set of three nucleotides called an anticodon.

All of the following are examples of environmental influences on the development of personality disorders except __________. A.
Elden [556K]

The answer is C. This is because the other choices involve experiences (most during childhood a significant phase in humans development) that are environmental factors that impact on the human personality. In choice C, there is little development since its adulthood phase and on the other hand, refusing to display warmth and emotion is not an experience.

write a 5-7 paragraph explaining what you think is happening to the earths co2 levels through the year.
jeka57 [31]

Answer:

Climate change has been described as one of the biggest problems faced by humankind. Carbon dioxide is is the primary driver of global warming. Prof Joanna Haigh from Imperial College London explains why this gas has played a crucial role in shaping the Earth's climate.

Carbon dioxide (CO2) has been present in the atmosphere since the Earth condensed from a ball of hot gases following its formation from the explosion of a huge star about five billion years ago.

At that time the atmosphere was mainly composed of nitrogen, CO2 and water vapour, which seeped through cracks in the solid surface. A very similar composition emerges from volcanic eruptions today.

As the planet cooled further some of the water vapour condensed out to form oceans and they dissolved a portion of the CO2 but it was still present in the atmosphere in large amounts.
