Answer:
Option (3).
Explanation:
The homeostasis of the body is maintained by the feed back loop system. Two main types of the feedback loop system of the body are positive feedback system and negative feedback system.
Positive feedback system may be defined as the feedback in which the final product increases the output of that product. Pepsinogen is an zymogen that helps in the activation of pepsin enzyme. This enzyme helps in the digestion of protein. The digestion of pepsinogen by pepsin result in the more production of pepsin.
Thus, the correct answer is option (3).
It seems that this question is fairly simple, as you may know kinetic energy is stored and used as potential energy, therefore the answer is B. some of the potential energy is transformed to kinetic energy...
Answer:
1. A locatable region of genomic sequence, corresponding to a unit of inheritance which is associated with regulatory regions, transcribed regions, and/or other functional sequence regions.
2. Were historically defined as the unit of hereditary material that causes a phenotype.
3. May be composed of a union of genomic sequences encoding a coherent set of potentially overlapping functional products.
Explanation:
A gene is a sequence of nucleotide present on a chromosome which determines a trait of an organism. The gene term was provided by the Wilhelm Johannsen in 1909 to refer to the hereditary unit of the organisms.
The genes in eukaryotes are not necessary that they will code for the protein as there are some RNA molecules which are not translated into the protein like rRNA and tRNA molecules.
The sequence of a gene in eukaryotes is a union of the regulatory of the functional and transcribed genes.
Thus, the selected option is correct.
Strands of tough connective tissue connect the skeletal muscles to bones. These strands of tissue are called tendons. When a muscle that connects two bones gets shorter, the bones are pulled closer to each other. (I got this answer from google sorry if it doesn’t help your problem)
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.
