I would make a spray that is not harmful to the environment, but instead it kills mosquitoes. If any other animals eats this, they will not die. It is for mosquitoes specificly.
Answer:
Both show the characteristic of a living organism
Explanation:
A thing can be considered a living thing if it fulfills the criterion of a living organism or in simple terms the characteristics of a living organism. In the given question, the two features that are growth in the mass and size of the sliver are measured and observed through the microscope.
Since the growth is the characteristic feature of the living organism and the substance fulfills this condition therefore the specimen is considered a living organism.
Thus, both show the characteristic of a living organism is correct.
The answer is protein synthesis
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
Answer:
Potassium
Explanation:
Potassium is the major cation of intracellular fluid and is involved in the normal functioning of neurons and muscles. Adequate intracellular levels of potassium are also required for many vital metabolic activities.
Nerve and muscle cells need to balance the intracellular potassium ion concentration as relative concentrations of potassium ions in intracellular and extracellular fluid regulate their resting membrane potential. Increased extracellular concentration of potassium depolarizes these cells while its reduced levels cause hyperpolarization making the nerve cells and muscle cells non-responsive.
Similarly, heart cells need to maintain the potassium levels as its imbalance disrupts the electric conduction in the heart and may even cause sudden death. Being a part of buffer system of cells, potassium ions maintain the pH of body fluids.
