Perhaps the bird’s calls could be less attracting and disorienting to predators and the ones with the said distinctive calls could have survived to repopulate and pass down the genes.
Answer: The correct answer is-
an agent that causes a mutation in DNA.
Mutagen is an agent or a substance that causes permanent change in the genetic material of living organisms ( DNA, deoxyribonucleic acid). This process is called mutation.
A mutagen can be a chemical, physical or biological agent that causes mutation in the DNA.
Example- Physical agents such as -
- Ionizing radiations like alpha particles, gamma rays, X-rays that brings break in the DNA and cause other damages.
- Ultraviolet radiations that creates pyrimidine dimers ( T=T) and causes replication errors if damage is not repaired.
Answer:
free molecules; plasma membrane
Explanation:
-Venom are complex mixtures of molecules called "toxins"
-Plasma membrane is the membrane found in cells that separates the interior of the cell from the outside environment
Please be informed that plants which are adapted to grow in water are known as <u>aquatic</u> <u>plants</u> eg: lotus and hydrilla
However, the observable characteristics of plants which grow on water are:
- Deeply dissected and waxy leaves
- Specialized pollination mechanism variation in growth pattern.
<h3>What are living organisms?</h3>
Living organisms; be it plants or animals are any organic or living system which is composed of cells and function as an individual entity.
- Generally, all living organisms share a number of key characteristics or functions such as movement, respiration, homeostasis, reproduction, growth, evolution, competition and others.
- Animals and plants also posesses systems such as the digestive, skeletal, transport, nervous, excretory, respiratory and reproductive system.
- Living organisms are also taxonomically classified as either unicellular microorganisms or multicellular plants and animals
So therefore, please be informed that plants which are adapted to grow in water are known as aquatic plants eg: lotus and hydrilla

Triglycerides and cholesteryl esters are transported in the core of plasma lipoproteins. The intestine secretes dietary fat in chylomicrons, lipoproteins that transport triglyceride to tissues for storage. Dietary cholesterol is transported to the liver by chylomicron remnants which are formed from chylomicrons.
