Answer:
Heart attack
Explanation:
Heart attack is the death of a part of heart muscles and severe pain that causes heart constriction having pain in the chest which spread to the left shoulder and down the arm thereby causing the feeling of pressure in the chest.
This is caused when a blood clots blocks blood flow to the heart thereby leading makes the tissue to loss oxygen and die.
The symptom of heart attack are;
pain in the chest, neck, back or arms, fatigue, lightheadedness, abnormal heartbeat and anxiety, nausea.
Treatment ranges from surgery, medication , rehabilitation e.t.c.
Most plants grow from seeds. These seed plants fall into two groups, <u>angiosperms</u> and <u>gymnosperms</u>.

Answer:
La diversidad de un ecosistema depende de dos factores, el número de especies presente y el equilibrio demográfico entre ellas. ... Por otra parte, entre dos ecosistemas que tienen el mismo número de especies, consideraremos más diverso al que presenta menos diferencias en el número de individuos de unas y otras especies.

Answer:
Option (3)
Explanation:
Unconformity is defined as the gaps in the sequence of geological rocks. It is a geological contact that marks the boundary between the different types of rocks. In simple words, they are also known as the time of non-deposition. These unconformities have great significance in the field of geology. They are of 4 types, namely-
(1) Angular unconformity- The sedimentary rocks are initially formed and deposited in an area, after that the area is tilted and erosion takes place. Now, the new sediments are deposited forming an angle, which is commonly known as an angular unconformity.
(2) Non-conformity- When the sedimentary rocks are deposited over the igneous or metamorphic rocks, then it is known as the non-conformity.
(3) Para conformity- When the sedimentary rocks are deposited parallel to the ground surface, and absence of erosion activity, then these surface appears to be a normal (simple) bedding plane. This is known as the para conformity.
(4) Disconformity- When the sedimentary rocks are formed and undergoes erosion, then new sedimentary rocks are deposited over this and diminishes the unconformity. This forms a discontinuity.
Thus, the unconformity arises due to both erosion and lack of rock deposition.
Hence, the correct answer is option (3).
All of the above are true.
A is correct, because, well. We can’t see atoms directly, at least not with our current levels of technology.
B is correct because a model is a representation of something by nature.
C is correct because our knowledge of the atom is still growing, and as we still don’t know about some future atomic developments, it’s called a model so that there’s still flexible room for new discoveries.
Hope this helps!
