Answer: In the stomach, oesophagus and intestines.
Explanation: Parastalsis is an involuntary wave-like movement of the bolus(food) and chyme by muscle contractions in the digestive tract. It occurs in the oesophagus, stomach and intestines. This happens by relaxation of circular smooth muscles allowing the bolus to pass and contract again to propel it forward. It goes on like that until it is secreted in the anus. Parastalsis is not limited to the digestive tract but also takes place in other hollow tubes in the body.
Increases in both macropredator populations and wildlife killing cattle have been noted.
<h3>When the top predators are eliminated, what happens?</h3>
Due of their ability to control prey populations, predators are crucial to ecosystems. Prey can overpopulate if there are no predators. It may also cause disease outbreaks that spread to domesticated animals and harm to nearby plants and plants.
<h3>What impact does the absence of predators have on the ecosystem?</h3>
It was observed that the absence of significant predators in forest ecosystems has allowed game animal numbers to skyrocket, stunting the growth of young trees and lowering biodiversity. Less carbon is sequestered as a result of this, which raises the possibility of climate change and contributes to deforestation.

The common function of antennae in arthropod is to smell
Explanation
Antennae are a long sensory appendages on the head of insects, crustaceans and some arthropods. They are usually covered with alfactory receptors that can detect odor molecules in the air that is the sense of smell, therefore they are the noise of insects and some arthropods

Answer: (C) The production of tissue-specific proteins.
Explanation:
The cell differentiation is the process in which the cell change from one cell place to another place. It basically occur due to the process of gene expression.
The cell differentiation involve the production of the specific tissue protein known as muscle actin. In cell differentiation, the pluripotent stem cell basically go in the specific differentiation level and then reach in the state of fully differentiation.
The fully differentiation produced a specific function that the production of the protein. Therefore, option (C) is correct.
