Answer: 1. Magnetic lines of force start from the North Pole and end at the pole, they're continuos through the body of the magnet
, Magnetic lines of force can meet up with iron more easily than air.
, Two magnetic lines of force can't intersect one another, they have a tendency to contract longitudinally., they have an inclination to expand laterally.
Answer:
Experiment to prove the necessity of carbon dioxide in photosynthesis - definition. Insert a part of the leaf of a destarched plant into a conical flask containing potassium hydroxide. Potassium hydroxide solution absorbs the carbon dioxide gas from the air present in the glass bottle.
The mitosis process of the cell will be inhibited in the saline environment.
Due to the response to water and salt stress that occurs via ABA which increases the expression of ICK1 that interacts with CDKA and inhibits histone H1 kinase activity (a protein involved in chromatin formation during phase S of the interphase).
This phenomenon is applied to highlight in the living cell the existence of chromosomes at the interphase, thus demonstrating the permanence of the chromosomal structure.
In eukaryotes, ribosomes become associated with endoplasmic reticulum membranes when a signal sequence from the RNA is given. <span>In the cytoplasm, ribsomal RNA (rRNA), a type of RNA, and protein
combine to form a nucleoprotein called a ribosome. The ribosome serves as
the site and carries the enzymes necessary for protein synthesis. They are
often takes the shape of small round particles attached in the endoplasmic
reticulum. The ribosome attaches itself to m-RNA and provides the stabilizing
structure to hold all substances in position as the protein is synthesized. An example of a eukaryote is the protists. </span>Protists belong to the group eukaryotes (having their DNA enclosed
inside the nucleus). They are not plants, animals or fungi but they act like
one. They can be in general subgroups such as unicellular algae, protozoa and
molds. They thrive in environments with little sunlight.
