Answer:Option C. gravitational, electric, and magnetic fields
Explanation:
An electron is a negatively charged particle having mass, m = 9.1 × 10⁻³¹ kg and charge, q = -1.602 × 10⁻¹⁹ C. Gravitational field is created all bodies having mass. Hence, a moving electron also creates gravitational field.
A charged body creates electric field around it. And when the charged body moves, it also creates magnetic field. Hence, a moving electron creates gravitational field, electric field and magnetic field.
Therefore, the correct answer is option C.
b. habitat loss
c. oil spills
d. all of the above
Answer:
D is the correct answer
Explanation:
B.Open meadows help to filtr out pollutants in the water.
C. Dense vegetation allows for biological magnification in the water.
D. Open meadows allow for biological magnification in the water.
Answer:
a
Explanation:
B. Blood components are continuously circulated through the blood vessels.
C. Blood components are continuously produced in the bone marrow.
D. Blood components are continuously digested by enzymes.
Answer: The correct answer is- C. Blood components are continuously produced in the bone marrow.
Formation of blood cells is a continuous process that occurs in the bone marrow ( a gelatinous, soft tissue present within bones) of adults.
This process is called as hematopoiesis, in which undifferentiated precursor cells ( also called stem cells) are developed and differentiated into particular blood cell type ( having specific function).
Thus, through this continuous process, all the components of blood can be replenished whenever they are required.
Therefore, when a person donates blood, he never run out of it.
The correct order of events during the synthesis of a specific protein would be:
The first step in the synthesis of protein is that genetic information for s specific trait on DNA is transcribed to messenger RNA in a process known as transcription.
Thereafter, the mRNA moves into the cytoplasm and gets attached to the ribosome. Another RNA, a tRNA that carries the amino acids that correspond to the genetic codes on the mRNA, moves to bind to the mRNA using its anticodon.
The codons are read in groups of 3s and the amino acids corresponding to each codon will get released from the tRNA at their respective turns. The released amino acids are joined together by a peptidebond to form protein.

Answer:
The correct order is: b), e), a), c) and d)
Explanation:
Messenger RNA leaves the cell nucleus and moves through the cytoplasm. During protein synthesis, the ribosome reads the base sequence of messenger RNA, and uses DNA to translate each codon triplet, into its respective amino acid. The RNA is synthesized in the nucleus and then later leaves the cytoplasm for the translation process. In general terms, DNA is transcribed into a messenger RNA molecule, so that a certain protein is produced
