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.

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

Scientific investigations often lead to the formulation of new scientific questions. The observations Charles Darwin's work after he returned home from his voyage prompted him to ask which question?.
-Are the Galapagos finches and people at the mainland equal species.
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.
What are finches?The Galapagos finches are divided into 3 corporations: the floor finches, tree finches, and Warbler finches.

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.

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

Kiran wonders, "Will colored light affect the growth of a plant?" Kiran writes in her notes that adding a colored filter over a plant affects its growth because the heights of the plants under the colored filters were less than the height of the plant with no filter.

A)low,fast C) high slower
B)high,fast. D) low, slower
Leaves in areas of low humidity have a steeper concentration gradient so water diffuses out of the leaf fast.
What is humidity?Humidity is used to determine the concentration of water vapour that is available in the air.
when the vapour is high there is high relative humidity when the vapour is low there is low relative humidity and water leaves the surface of leaf fast.
Therefore, Leaves in areas of low humidity have a steeper concentration gradient so water diffuses out of the leaf fast.

How does apoptosis relate to cancer cells?
A. In cancer cells, too much apoptosis occurs, resulting in malignant cells that will not undergo programmed cell death.
B. In cancer cells, too little apoptosis occurs, resulting in malignant cells that will not undergo programmed cell death.
C. In cancer cells, apoptosis occurs only when cells grow without proper regulation.
D. In cancer cells, apoptosis occurs only when the cells receive the proper hormones.
Answer:
Apoptosis in Cancer
The loss of apoptotic control allows cancer cells to survive longer and gives more time for the accumulation of mutations which can increase invasiveness during tumor progression, stimulate angiogenesis, deregulate cell proliferation and interfere with differentiation
Many oncogenic stresses, including uncontrolled proliferation or DNA damage, trigger apoptosis; consequently, by culling cells at risk of transformation, apoptosis effectively prevents cancer. Apoptosis also suppresses tumourigenesis in various other ways.
The more malignant the tumour is, the more apoptosis shows. In this study, we propose a new theory that apoptosis plays a key role in the malignant progression and metastasis of cancer. The growth of tumour is the difference between tumour cell proliferation and attrition plus the hyperplastic growth of stroma.
What is the role of camp in the signal transduction pathway activated by epinephrine?.
Answer:
When activated, adenylyl cyclase converts a large number of ATP molecules into signaling molecules, called cyclic AMP (cAMP). Because cAMP carries the message of the first messenger (epinephrine) into the cell, cAMP is referred to as a second messenger.
Explanation:
Adenylyl cyclase turns a large number of molecules of ATP into the signaling molecules cyclic AMP when it is activated (cAMP). cAMP is referred to as a second messenger because it delivers the signal of the first messenger (epinephrine) into cell.
What is cAMP?Cyclic adenosine monophosphate, often known as cyclic AMP or cAMP, is a tiny, hydrophilic molecule that functions as an essential intracellular second messenger molecule that is controlled in a variety of physiological activities.
It is now understood that cAMP regulates cellular activity in all organisms, including amoebas, plants, and people. The biological functions of memory, metabolism, gene regulation, and immunity are all mediated by this second messenger.
Therefore, Adenylyl cyclase turns a large number of molecules of ATP into the signaling molecules cyclic AMP when it is activated (cAMP). cAMP is referred to as a second messenger because it delivers the signal of the first messenger (epinephrine) into cell.
