Answer:
They digest without the use of teeth.
Explanation:
The food trickles from the crop into the bird's stomach (proventriculus or gizzard) where digestive enzymes are added to the mix and physical grinding of the food occurs. The gizzard is why chickens do not need teeth.
Answer:
A rise in blood carbon dioxide concentration.
Explanation:
The feedback regulation may be defined as the process in which the end product of the metabolic pathway regulates the homeostasis of the body. Two main types of feedback are positive feedback and negative feedback.
The negative feedback mechanism occurs when the end product of the reaction is responsible for the shutdown of the metabolic pathway and decreases its concentration. The breathing is controlled by the negative feedback mechanisms, the increase in carbon dioxide concentration acts as the negative sensor as this sensor is mainly responsible for the increase in amount of oxygen level and maintain homeostasis of the body.
Thus, the correct answer is option (c).
You can conclude that the father was either heterozygous for that trait or fully homozygous.
D) because those birds are scavengers and therefore there will be competition in finding food and then to fight off the other birds so that you can get the food first.
