Biomes are described in terms of abiotic factors like soil type and climate, and biotic factors factors like plant and animal life.
1. Latitude and the heat transported by winds are two factors that affect global climate.
2. Other factors, among them an areas proximity to an ocean or mountain range also influence climate.
Answer:
Option (c).
Explanation:
Eukaryotes may be defined as the organism that contains the well defined nucleus and membrane bound cell organelle. The eukaryotes contains morte cell organelles as compared with prokaryotes.
The ribosomes of eukaryotes are larger than the ribosomes of prokaryotes. The 80'S ribosomes are present in eukaryotes whereas 70'S ribosomes are present in prokaryotes.
Thus, the correct answer is option (c).
A flagella helps an animal sperm move!
Answer:
3. is activated immediately upon infection.
Explanation:
Innate immunity is the nonspecific immunity. These immune defenses are present at birth and do not involve specific recognition of a microbe. Being nonspecific in nature, it acts against all microbes. Innate immunity includes the first and second lines of defense.
Some of the examples of components of innate immunity among the first line of defenses are physical and chemical barriers of the skin and mucous membranes. Innate immune responses are the immunity’s early warning system that is generated immediately after the encounter with a pathogen to prevent them from entering the body and to help eliminate the ones that have entered the body.
Once a microbe has entered the body, secretion of antimicrobial substances and activities of natural killer cells, phagocytes, the process of inflammation, etc. serve to eliminate it from the body. All these responses are the components of innate immunity.
Answer:
4. Ribosomes are tiny glanular structures that are either floating freely in cytoplasm or are bound to endoplasmic reticulum.
5. Translation.
6. Eukaryotic ribosomes are ten times larger than prokaryotic ones.
7. Not sure about this.But they are necessary for protein synthesis as they assemble amino acids into protein chains.
8. Ribosomal RNA is part of ribosome.These complex structures catalyze the assembly of amino acids into protein chains.They also bind tRNAs and various accessory molecules necessary for proteins.
9. When a ribosome is not working,it disassembles into two smaller units.
