What is the physical appearance of an animal known as?
The phenotype is the physical appearance of an organism or the different traits it expresses.
Why do animals have patterns?
The patterns or stripes present on the body of animals match with their surroundings like grass, plants etc. These prevent animals from being spotted by predators easily. For example, When Zebra hides itself behind the grass, these stripes confuse predators in identifying it thereby provides protection.
What defines animal diversity?
The diverse appearance of animals is mostly superficial; the bewildering variety of known forms, some truly bizarre, can be assorted among a mere half-dozen basic body plans. These plans are established during the embryonic stages of development and limit the size and complexity of the animals.
Which of the following is the actual physical appearance of an organism?
phenotype
The observable traits expressed by an organism are referred to as its phenotype. An organism’s underlying genetic makeup, consisting of both physically visible and non-expressed alleles, is called its genotype.
What two characteristics describe animals?
Which two characteristics do all animals have? Their cells have a nucleus and membrane-bound organelles.
Why do animals have spots or stripes?
Most animals have stripes to either hide from predators or to hide from prey. In fact, camouflage is any pattern that helps an animal to hide. These patterns also include spots and splodges. They help animals to hide by breaking-up their shape or appearance when they’re surrounded by plants.
What causes stripes on animals?
The patterns depend on a chemical process called a reaction-diffusion model, first hypothesised by Alan Turing in the 1950s. If the embryo is very small, no pattern forms. Shape also plays a role: if part of the embryo of a potentially spotted animal is elongated, that part can become striped.
What is animal diversity and its importance?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
