Answer:
From Natural Numbers to Integers
Early civilizations found different ways to write numbers, but they all started with the same set of numbers preschool children learn today: the natural numbers (also called the counting numbers). These are the numbers 1, 2, 3, and so on—the numbers we use when counting.

Answer:
D. x2000
Explanation:
magnification = image(drawing size)/actual size
magnification = 40/0.02
magnification = x2000
Answer:
<em>The correct option is D. Plants</em>
Explanation:
Plants can be described as eukaryotic organisms which are able to make their own food. The process by which plants make their own food is termed as photosynthesis. During photosynthesis, plants convert water and carbon dioxide into glucose and oxygen in the presence of sunlight.
The oxygen produced by the land plants accounts for half of the oxygen present in the Earth. Hence, option D is correct.
Other options are false because none of them can carry out photosynthesis.
Answer:
Because the gametes implemented in fertilisation are haploid in nature, in the case of humans, mature gametes contain 23 chromosomes instead of 46 which will then combine with another parents' 23 chromosomes during fertilisation, i.e: 23 (dad) + 23 (mom) = 46 (zygote)
Explanation:
A regular somatic cell has 46 chromosomes, 2n, 2 alleles but the gametes have 23 chromomes, n, 1 allele. The usual significance of this is so that there is diversity in the offspring and the offspring can gain characteristics (bad or good) from both parents.
Answer:
The correct answer will be-predator-prey relationship.
Explanation:
The predator-prey relationship is the interaction between two species where one species is hunted by a hunter. The species which hunts is known as the predator while the species which gets hunted is known as the prey.
In the given question, since the number of rabbits increases which is the food of the fox in the food chain, therefore, the number of hunters in that area also increase.
Thus, this type of interaction is a predator-prey relationship.
