Answer: Whereas an atom whose outermost electron shell is completely filled is least likely to bond with other atoms as the atom is stable due to completely filled shell.
Explanation:
dont question my anwser just know its right
Answer:
All the statements are true except the second i. e. the soil quality in an ecosystem Does not matter as much as soil quantity.
Explanation:
In an ecosystem both quality and quantity of water is very important. If the quality of water is not suitable, that it contains polluted substances so the health of the organism such as fishes and other aquatic animals will adversely affected and sometimes dealth occurs and the ecosystem will be negatively affected.
What the larva and pupa stages have in common is that both stages take place in water.
This is where the insect evolves until it becomes fully grown and then leaves water.
A phylogeny is an evolutionary ”tree” of related
organisms that can be constructed by using
information obtained from the genetic material.
Genetic information is contained in all living cells,
in the form of long DNA molecules that take the
shape of connected double- stranded spirals
(DNA stands for deoxyribonucleic acid). DNA
spirals, or “helixes”, are tightly compressed in the
nucleus of every cell. Their information is
organized into a code made up of four small
molecules — the building blocks of DNA. The
molecules, called nucleotides, are labelled:
A (adenine), C (cytosine), G (guanine) and T
(thymine).
It is possible to draw conclusions about the
evolution of a group of plant or animal species,
and the relationships among them, by comparing
selected pieces of DNA.
The factors that affect temperature or altitude latitude and distance from sea the height measured from sea level is called altitude when the latitude increases the distance from the Sun Also increases so the temperature gradually decreases
