Answer: Staphylococcus aureus is a gram positive bacteria which is round shaped bacterium that is usually found in the body. They are located in the respiratory track of the body.
Saccharomyces cerevisiae is a yeast species which is used in the brewing, wine making and baking long time ago.
When both of the species were observed under microscope then Saccharomyces cerevisiae will be larger than Staphylococcus aureus.
Grasshopper and cricket are two organisms in the food web would MOST LIKELY be affected by a decrease in producers, or the plants, at the bottom base of the food web.
D) grasshopper and cricket
<u>Explanation:</u>
A food web comprises of many food chains. An evolved way of life just follows only one way as creatures discover food. It is an enormous number of plants and creatures things. A food web shows a wide range of ways plants and creatures are associated with one another for their prey.
Though Grasshopper and cricket are two living beings in the nourishment web that would be generally influenced by a diminishing in makers, or the plants, at the base of the nourishment web.
Like every living life form, crickets and grasshoppers assume a significant job in keeping up the equalization of the biological system. They breakdown plant material, restoring soil minerals. They are also an important source of food for other animals.
Answer:
C) the three-base sequence of mRNA
Explanation:
Three-base sequence of mRNA is called codon. One codon specifies a single amino acid. There are 64 codons in eukaryotic cells and three of them are stop codons (non-coding).
tRNA have three-base sequence called anticodon which is complementary to specific codon. During the process of translation codon and anticodon are paired which leads to addition of amino acid to growing polypeptide chain. Newly added amino acid is carried by tRNA.
Answer:
RNA
Explanation:
CRISPR system was discovered by a Japanese scientist. Naturally <u>bacteria and many other prokaryotes</u> have <u>CRISPR system in their genome</u> which they use as a<u> self defense against a pathogen</u> which is invading them. It consists of<u> inter spaced, short palindromic nucleotide repeats </u>which <u>encode a guide RNA (gRNA)</u>. This guide RNA (gRNA) recognizes the<u> target sequence</u> on the pathogen. The <u>gRNA is followed by Cas9 enzyme</u> which along with the gRNA plays a very important <u>role in breaking genome</u> of the pathogen. Once the target gene is cut down the rest of the DNA can be rejoined by<u> non homologous end joining. </u>
But nowadays, scientists are using this system for <u>genome editing</u> and <u>incorporating desired gene</u> between the two ends which are cut down by <u>CRISPR Cas9 system.</u>
