Answer:
The Microscope
Explanation:
Before the 1600s, every living thing was a part of a two kingdom classification system derivative of binomial nomenclature. This was proposed by Linnaeus, a Swedish Naturalist, who split all living things into either the animalia or plantae kingdom. After the invention of the microscope however, a new detailed classification system was put in order to accommodate for microscopic life. This new system recognizes the existence of 6 kingdoms: eubacteria, archaebacteria, prostista, fungi, plantae, and animalia.

According to the graph, which statement best describes the effects of increasing ozone on human health?
Lung function increases when ozone gas moves above 0.1 ppm.
O Lung function decreases as ozone gas moves below zero ppm.
Lung function increases at a faster rate for older people.
Lung function decreases at a faster rate for young people.
Answer: D) Lung function decreases at a faster rate for young people.
Explanation:
Look at the slope of the graph. If you look at it the other way, you will see that it is decreasing at an extreme rate.
For young people, lung function declines more quickly. Your lung function will typically deteriorate over time as you get older, starting around the age of 35.
What role does the lung play?The process of exchanging gases, known as respiration, is the lungs' primary purpose (or breathing). During respiration, carbon dioxide, a metabolic waste product, exits the blood and oxygen from the incoming air enters. A diminished ability of the lungs to exchange gases is referred to as a lowered lung function.
How many components are there in the lungs?Summary There are lobes on each lung. Alveoli, bronchi, and the windpipe make up the bronchial tree that runs through your lungs.

List 3 different proteins that can be made by a ribosome and explain their functions.
Answer:
Ribosomes receive information from the cell nucleus and construction materials from the cytoplasm. Ribosomes translate information encoded in messenger ribonucleic acid (mRNA). They link together specific amino acids to form polypeptides and they export these to the cytoplasm.
hope i m correct
Proteins are made by ribosomes. Examples of some proteins are insulin, glucagon, and keratin protein . Insulin and glucagon are glucose regulators in blood and keratin is structural protein.
How are proteins synthesised?Ribosomes are responsible for protein synthesis. The process of protein synthesis is called translation. For this process, ATP, translation enzymes, mRNA, and ribosomes are required.
In the cell, there are two types of ribosomes. Some are attached to the endoplasmic reticulum, and some remain free in the cytosol. The attached ribosomes give the endoplasmic reticulum its rough structure. Hence, this is called the rough endoplasmic reticulum ( RER).
The RER contains proteins or polypeptides that are destined to exist outside of the cell's synthesis. The proteins that remain in the cell are formed by the free ribosomes.
Examples of some are insulin, glucagon, and keratin proteins. Insulin is synthesised by beta cells of the pancreas and goes outside of the cell. Insulin maintains the blood glucose level. Glucagon increases the blood glucose level by breaking down glycogen. Keratin protein is the structural protein present in the hair.
Hence, three proteins are insulin, glucagon, and keratin that are made by ribosomes.

Describe the function of each organelle.
Nucleus
Endoplasmic reticulum
Golgi
apparatus
Ribosome
Answer:
Nucleus: The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material.
Ribosome: the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.
Endoplasmic reticulum: is a large complex of RNA and proteins. Ribosomes are the cell structures that make protein. They are found in the endoplasmic reticulum.
Golgi apparatus: The Golgi is the receiver of the entire output of the endoplasmic reticulum (ER), where proteins and lipids are processed, sorted, and packaged into vesicles and transport carriers for delivery to their final destinations inside or outside of the cell

An atom with 9 protons and 8 electrons is what kind of atom?
Hint: Cations have more positive charges than negative charges. Anions have more negative charges than positive charges. A neutral atom has the same number of positive charges to negative charges.
A
an anion
B
a cation
C
a neutral atom
Answer:
B. A cation
Explanation:
An atom is the smallest indivisible component of a matter including an element. An atom contains three particles called SUBATOMIC PARTICLES (PROTON AND NEITRON in the nucleus and ELECTRON surrounding the nucleus). The proton is positively charged while the electron is negatively charged.
The number of protons and electrons determine whether an atom will be postively charged (cation) or negatively charged (anion). In this question, an atom with 9 protons and 8 electrons will be A CATION because the protons (9) are more than the electrons (8), hence, making it a positively charged atom (cation).
N.B: The cation atom will have a +1 charge

Which of the following is most directly responsible for water's unique properties?
A It contains oxygen atoms.
B It contains hydrogen atoms.
C It is an ionic compound.
D It forms hydrogen bonds.
E It is nonpolar.
Answer:Water molecules are polar, so they form a hydrogen bond(s). This gives water unique properties, for example a relatively high boiling point, high specific heat, cohesion, adhesion and density.
Explanation:
The unique properties of water can be attributed to the fact that it forms hydrogen bonds.
HOW IS HYDROGEN BOND FORMED IN WATER:
Water is regarded as a special molecule because of its unique properties such as cohesion, adhesion etc. This unique properties of water can be attributed to the hydrogen bonding molecules of water. Water is made up of two hydrogen atoms and one oxygen atom. The hydrogen atoms of one water molecule forms an HYDROGEN BOND with the oxygen atom of another water molecule.Hence, the unique properties of water can be attributed to the fact that it forms hydrogen bonds.

When Darwin visited the Galapagos islands he determined that the small flocks of finches that existed there have been very much like the finches that existed withinside the mainland of South America besides for his or her beak form and feeding habits.
• This brought about him to invite the query that 'Are the Galapagos finches and mainland finches the equal species?'
• Later on research made it glaring that some corporations of mainland finches migrated to the Galapagos island and occupied unique niches.
They adjusted themselves to the island surroundings and developed with new variations in beak shape and feeding habits.
• They at the moment are labeled into 14 corporations out of which thirteen exist withinside the Galapagos island.
