From the knowledge of natural selection it is possible to say that:
A) Natural Selection
B) Industrial Pollution
C) In the clean environment the favored allel was the white winged moth. In the polluted environment the dark winged moth was favored.
What is a natural selection?
Natural selection is the evolutionary mechanism proposed by Charles Darwin, who stated that the environment acts as a selector of characteristics, perpetuating the organisms best able to survive in a given place.
A) moths are being selected because they are under pressure of Natural Selection. Selection is a composite of all the forces that cause differential survival and differential reproduction among genetic variants. Natural selection it is the machine which drives evolution.
B) The agent of selection was Industrial Pollution. Before industrialization , there were more white winged moths on trees than dark winged or melanised moths. But after industrialisation , there were more dark winged moths in the same area. The proportion was reversed.
C) In the clean environment the favored allel was the white winged moth. In the polluted environment the dark winged moth was favored. The area where industrialisation did not occur, the count of melanic moths was low. The area where industrialisation occured ,dark colored moths survived as they were able to camouflage themselves , with the tree trunks that had become dark due to industrial smoke and soot.

A. trachea
B. diaphragm
C. alevoli
D. bronchioles
Bronchioles are small, muscular tubes in the respiratory system that help regulate airflow. The correct option is B.
Bronchioles help regulate the airflow by contracting and relaxing their smooth muscles, allowing for adjustments in the amount of air entering and exiting the lungs
Their muscular walls can constrict or dilate, allowing the body to adjust the volume of air reaching different parts of the lungs based on factors like physical activity or oxygen demands. This regulation ensures efficient gas exchange and helps maintain optimal respiratory function.
Unlike the trachea and larger airways, bronchioles lack cartilage support, which gives them the flexibility to respond to the body's respiratory needs.

The moon is covered in Earth’s shadow.
Answer:
the Moon's shadow falls on Earth
Explanation:
The phenomenon in which the moon's shadow fall on earth or the earth casts its shadow on the moon is known as eclipse. During solar eclipse, moon's shadow falls on the earth. During lunar eclipse, earth's shadow falls on the moon.
٩ʕ◕౪◕ʔو
During a solar eclipse, the moon's shadow falls on Earth. Therefore, option (C) is correct.
When the Moon lines up between the Earth and the Sun, the Moon's shadow falls on the surface of the Earth. This is called a solar eclipse. This can only happen during a new moon, when the three stellar bodies are lined up in a straight line. During a cosmic event called an eclipse, the moon moves in relation to the Sun.
This causes the moon to block the Sun's light, which makes some parts of Earth temporarily darker or completely dark. Solar eclipses can be broken down into three different types: partial, annular, and total. These three types are determined by where the moon is in relation to the Sun and how big it seems to be. A solar eclipse takes place in the area where the moon's shade covers the sun. Therefore, option (C) is correct.

The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA.
Mitochondria play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.
Ribosomes are small cellular structures and are the site of protein synthesis. Ribosomes are found in all cells.
Chromosomes are very important because they contain vast majority of genetic information of organism. The organism's DNA is contained within the chromosome as a long series of nucleotides thar are organised into genes. And helps to inherit the characters of parents to their offsprings.
The nucleus is the control center of the cell. Chromosomes are structures in the nucleus that contain DNA. Mitochondria are organelles that are often called the "powerhouses" of the cell. Ribosomes are organelles that are responsible for protein synthesis.
Nucleus: It contains the cell's DNA, which is the genetic material that determines the cell's structure and function. The nucleus also contains proteins that are involved in gene expression, which is the process by which DNA is decoded to produce proteins.
Chromosomes: There are 23 pairs of chromosomes in human cells, for a total of 46 chromosomes. The chromosomes are made up of DNA and proteins, and they are responsible for storing and transmitting genetic information.
Mitochondria: They are responsible for producing ATP, which is the cell's main source of energy. Mitochondria are surrounded by a double membrane, and the space between the membranes is filled with a fluid called the mitochondrial matrix. The mitochondrial matrix contains enzymes that are involved in the production of ATP.
Ribosomes: They are made up of two subunits, and they are located in the cytoplasm of the cell. Ribosomes can also be found attached to the endoplasmic reticulum. Proteins that are synthesized by ribosomes are used by the cell for a variety of purposes, including structure, metabolism, and transport.
