Answer:
23 chromosomes.
Explanation:
Meiosis is the process by which the chromosome number is halved during gamete formation. So chromosomes are 46 and get halved to 23 during the process of meiosis.
<span>G1 stage is the first of four periods of the cell cycle that occur in eukaryotic cell division. In this piece of interphase, the cell orchestrates mRNA and proteins in readiness for resulting steps prompting mitosis. G1 stage closes when the cell moves into the S period of interphase.</span>
Answer – The Tide
The regular rising and falling of ocean water due to the gravitational pull of the Sun and Moon is known as the ocean tide. Primarily, it is the moon that is chiefly responsible for the rising and falling of ocean water; the gravity of the sun only reinforces the moon's gravity.
In the simulation, the prey type that will avoid capture the most is the beans while the predator that will succeed in capturing the most prey is the spoon.
<h3>What are predator-prey relationships?</h3>
Predator-prey relationships are feeding relationships in which one organism kills and eats another organism for food.
The organism that kills the other is called the predator while the organism that is killed is called the prey.
In the simulation, the prey type that will avoid capture the most is the beans since it had the smallest surface area and size.
The predator that will succeed in capturing the most prey is the spoon because of its hollow nature.

Answer: Option B
Explanation: The first line of defense acts a barrier and does not allows the foreign materials to enter inside the body. It includes chemical and physical barriers that are always ready to protect the body from infection.
Example: Skin and mucous membrane.
Skin is largest organ and it acts as a barrier between pathogens and human body. It acts a waterproof material and the pathogens cannot get inside through skin unless the skin is broken.
Mucous membranes also acts as first line of defense and breaks the cell wall of many bacteria entering through the openings of the body.
So, skin and mucous membrane are the first line of defense.
