<h3>What is a constant factor?</h3>
In an experiment, a constant factor is one that is not allowed to change al through the experiment. This one must be held as the same and not allowed to vary. A constant factor could be the dose of the drugs and the species of the rats used.
The factor that would be different for the experimental group and the control group the administration of the new drug.

Answer:
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, to spawn refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and reptiles, reproduce through the process of spawning.
Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mosquitoes and corals, which are actually small aquatic animals—not plants. Fungi, such as mushrooms, are also said to "spawn" a white, fibrous matter that forms the matrix from which they grow

A polysaccharide called starch consists entirely of glucose molecules. during early stages of starch digestion, starch would be broken down into<u> Maltose
</u>
<u>Explanation:
</u>
The start of the digestion happens in the mouth which is the first organ of the digestive system; the mouth contains salivary amylase that is present in the saliva.
<u>The complete hydrolysis of starch yields, in successive stages, glucose:
</u>
<em>starch → dextrins → maltose → glucose
</em>
This amylase breaks down starch into several units of Maltose and sends it to the next organ. This partially digested starch is completely digested into several glucose molecules in the intestine by various enzymes.
Maltose or malt sugar, is a disaccharide comprised of two glucose molecules. The most well-known disaccharide is sucrose, which is made of glucose and fructose.

Answer:
While on his voyage on the Beagle,while in Galapagos Island he observed that Finches(birds) across the island are similar but different in the structure of their beaks. This mystified him and he puzzled on thus on why there were differences in the beaks shapes.
He therefore postulated from the observation that beak shapes of these birds must be responsible for the adaptation to their habitats.Thus these birds must have come from common ancestors,(and the need to survive by adaptations to different environments is responsible for the beak shapes). The driving force for these phenomena is Natural selection.Therefore,where the size of beaks is the needed adaptation for survival,birds with larger sizes will be selected over those with smaller beaks for eating Feeds(selection pressure) and therefore will be better adapted and naturally selected than smaller birds.
Darwin predicted that the dormant traits(large beaks) will remain in the population as the parents pass these to their offspring from generation to generation,while the population smaller beaks which could not resist the selection pressure will fizzled out.
Thus the better adapted larger beak population will dominate and evolved after a long period of time.Thus all organisms with adaptations and naturally selected on earth must have evolved from a common ancestor.
Although Darwin proposed these,he lacks knowledge of genetics,therefore he could not explain how dominant traits for adaptation are inherited from one generation to another.However,mutation which gives rise to variations is driving force for the changes in structural characteristic for adaptation.Gene flow,gene drifts,together with natural selection are the driving forces.
