An enzyme is a catalyst for chemical reactions. Catalyst means that it "speeds up" something. This means that the answer is:
B) Increases the rate of a chemical reaction

True
Explanation:
Atoms of different elements have different masses because different atoms have a different number of subatomic particles i.e neutrons, protons and electrons.
Answer:
abundance and occurrence are linearly related
Explanation:
The core-satellite hypothesis states that several species will be widespread and several species will be scarce. This is based on the assumption or prediction that species habitation is distributed bimodally.
Hence, according to the core-satellite hypothesis, it is believed that "abundance and occurrence are linearly related."
As there is an increase in the level or number of species, the chance of occurrence or seeing their species increases.
Answer:
During translation process tRNA move from one binding site of ribosome (A site) towards P site.
Explanation:
Ribosome is composed of two sub units, one small and other large. It contain three binding sites for tRNA.
1. Peptidyl site:
It help in holding newly growing polypeptide chain of amino acid.
2. Acceptor site (A site):
It help in receiving and holding aminoacyl tRNA which hold amino acid that will be added to polypeptide chain.
3. Exit site (E site):
That site where tRNA leave its amino acid.
The process of translation consists of three main steps:
1. Initiation:
In this step mRNA bind to ribosomal sub unit.
2. Elongation:
The ribosome read the mRNA by joining with tRNA and help in the formation of polypeptide chain.
3. Termination:
When ribosome reach to stop codon translation stop.
When the process of translation is started, initiator tRNA carrier of methionine amino acid come and set on start codon (AUG) located in A binding site of larger subunit of ribosome. As ribosome move along mRNA attached tRNA to mRNA is shifted to p site from P to E site. It should be cleared that prolypeptide chain grow in nitrogen to carboxyl direction.
Mars and Earth are very different planets when it comes to temperature, size, and atmosphere, but geologic processes on the two planets are surprisingly similar. On Mars, we see volcanoes, canyons, and impact basins much like the ones we see on Earth
