Answer:
The answer is; D
Archaebacteria are early life forms on earth. They utilized the process of chemosynthesis to make organic molecules from inorganic molecules and for energy. The word archae means ‘ancient’ life forms. These single-celled organisms evolved around sulfur-rich environments of the hydrothermal vents.
B.False. Animals usually reproduce sexually, most are not made to reproduce asexually. Plants reproduce asexually.
Answer:
Air temperature
Explanation:
Air temperature is being described by Jade according the properties highlighted.
The degree of hotness or coldness of a body is known as its temperature.
- As you go higher it becomes cooler. The surface causes the warming of the air around.
- With height, the surface is distant from the body of air.
- On summer days, air temperature is higher due to more insolation.
- Weather maps gives a good description of air temperature from places to places.
Answer:
The most appropriate answer would be (3) nucleus and ribosome.
A nucleus is the controlling center of the cell which contains genetic material of the cell that is, deoxyribonucleic acid (DNA). DNA codes for mRNA (messenger ribonucleic acid) which carries the codes for protein synthesis from DNA (nucleus) to the ribosomes.
Ribosome forms the site for protein synthesis in the cell. Ribosome forms the complex around the initiation codon of the mRNA and then moves along the length of mRNA.
As ribosome moves, tRNA (transfer RNA) keeps adding specific amino acids to the growing polypeptide chain according to the codon sequence of mRNA.
Ribosome releases the mRNA and newly synthesized polypeptide chain as soon as it reaches the termination codon of the mRNA.
Answer:
A restriction enzyme is a protein that recognizes a specific, short nucleotide sequence and cuts the DNA only at that specific site.
