Answer:(1) TIGHT JUNCTIONS
(2) DESMOSOMES
(3) GAP JUNCTIONS
(4) GAP JUNCTIONS
(5) DESMOSOMES.
Explanation: TIGHT JUNCTIONS also known as OCCLUDING JUNCTIONS are junctions present between adjacent cells,tight junctions prevent the passage of materials between the extracellular space of cells.
DESMOSOMES are adhesive intracellular junction connecting adjacent cells,they are also known as anchoring joints which are known to present in tissues where stress are expected.
GAP JUNCTIONS are junctions between cells which allows the movement of ions and small molecules and present in electrically exciteable tissues.
In general, the most abundant gas in earth is oxygen, since it's one of the elements in water. However if specifically in the atmosphere, nitrogen is the most abundant gas with 78%.
Answer:
reacting with nitrogen and oxygen atoms in DNA, these compounds modify certain nucleotides so as to distort the normal pattern of base pairing. If these modified nucleotides were not repaired, they would allow an incorrect nucleotide to be incorporated during replication.
Explanation:
Answer;
-Non-foliated metamorphic rocks
-Metamorphic rocks that don’t have layers are called non-foliated metamorphic rocks.
Explanation;
-Metamorphic rocks are rocks that go through heat and pressure and change form. They can be formed by pressures deep inside the Earth, by tectonic processes such as continental collisions, or when they are heated up by an intrusion of hot molten rock called magma from the Earth's interior.
-Foliated metamorphic rocks have a layered or banded appearance that is produced by exposure to heat and directed pressure, they include rocks such as gneiss, phyllite, schist, and slate.
-On the other hand,Non-foliated metamorphic rocks do not have a layered or banded appearance, they include rocks such as hornfels, marble, quartzite, and novaculite.
