Answer:
Hardy-Weinberg equilibrium
Explanation:
The Hardy-Weinberg law is established in it is that in a sufficiently large population, in which the matings occur randomly and that is not subject to mutation, selection or migration, the gene and genotype frequencies remain constant from generation to generation, once a state of equilibrium has been reached that is reached after one generation at autosomal loci. A population is said to be in equilibrium when alleles from polymorphic systems maintain their frequency in the population through generations.

Answer:
Book lungs are within small openings in the abdomen of the arachnid. The book lungs themselves consist of a series of haemolymph filled plate-like structures. Between the plates there is an air space and this allows air to circulate around the plates. Gaseous exchange then occurs through the surface of the plates.

Which organelle converts sugars into energy?
A. lysosome
B. mitochondrion
C. nucleus
D. ribosome
The organelle that converts sugars into energy is the mytochondrion, which is the powerhouse of the cell, so the correct option is B. mitochondrion
Which organelle converts sugars into energy?The mitochondrion is often referred to as the "powerhouse" of the cell because it is responsible for generating energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration.
During cellular respiration, glucose (a sugar) and oxygen are metabolized within the mitochondria to produce ATP, which serves as the primary energy currency of the cell. The mitochondria are present in most eukaryotic cells and play a crucial role in energy production.

A student is observing an image of an object that could be a comet, meteoroid or asteroid. Which of the following questions
would BEST confirm that the object is a comet?
A. Does the object contain ice?
B. Does the object contain metals?
C. Where is the object found?
D. How big is the object?
Answer:
A does the object contain ice
Explanation:
The BEST question that would confirm that the object is a comet is "Does the object contain ice?" Hence the correct option is A.
What are comets?Comets are small, icy celestial bodies that originate from the Kuiper Belt and the Oort Cloud. As they approach the Sun, they heat up and release gas and dust in the form of a coma and a tail, which can be observed from Earth. Therefore, if the object contains ice, it is most likely a comet.
Meteoroids, on the other hand, are smaller rocks that travel through space, and asteroids are larger rocks that orbit the Sun between Mars and Jupiter. Neither meteoroids nor asteroids typically contain ice.
As for the other options, whether the object contains metals or how big it is does not provide enough information to determine whether it is a comet, asteroid, or meteoroid. And while the location of the object may provide some clues about its origin, it is not a definitive factor in determining whether it is a comet.
