Answer:
A
Explanation:
The energy carried by electromagnetic waves is sometimes referred to as radiant energy. Electromagnetic waves do not require a medium for propagation hence they can travel through vacuum and are known to transmit enormous amount of energy.
Electromagnetic waves transmit energy away from the source of the wave. Hence the answer chosen in the answer section above.
Answer:
b. "C" “B” “A,” “D”
Explanation:
C is prophase because the nuclear envelope starts to disappear and the centrosomes divide
B is metaphase because chromosomes line up to form the equatorial plate
A is anaphase because the sister chromatids are separated
D is telophase because new nuclei form around the separated genetic material
Answer:
A. Pathogen- 4
B. aerobic- 7
C. hypothesis- 6
D. herbivores- 2
E. one another differentiation -5
F. homeostasis- 1
G. metabolism- 3
Explanation:
A. Pathogen- a pathogen is a living organism which can feed on other organism and can utilise their cellular components for their own survival. This affects the host cell and they get infected and the pathogen thus causes disease.
B. Aerobic- The oxygen appeared on Earth later compared to the time life originated on earth. Therefore some organism living today can use oxygen for survival and some not. The organism which utilises oxygen for their survival is known as aerobic microorganisms.
C. Hypothesis- The hypothesis is a predicted statement formulated based on the study related to the natural event which can explain the natural event.
D. Herbivores- The organism which cannot make food for themselves on their own but rely on another organism, especially the plants, are known as the herbivores.
E. Differentiation- Differentiation is the process which forms a variety of cells from a single cell and can perform different functions.
F. Homeostasis- is the mechanism which can maintain the internal conditions of the organisms.
G. Metabolism- refers to the chemical reactions which can help perform the normal functioning of the organism.
Ans. (4). protein synthesis.
Protein synthesis can be defined as a process that involves formation of polypeptides or proteins by using information present in DNA. It is divided into two steps, transcription and translation.
During transcription, DNA is transcribed into mRNA and information present in DNA is transferred to mRNA as codons. Codons represent triplet of nucleotides and each codon codes for a specific codon.
Translation involves formation of protein, during which amino acids are added to the growing polypeptide chain with the help of codons.
The given diagram represents process of translation. Thus, the correct answer is option (4).
Answer:
Chromosomal non‐non disjunction resulting in extra sets of genes
