Oxygen and Selenium
Explanation:
Elements will have similar chemical properties if they have the same amount of valence electrons. Core electrons are not evaluated when comparing chemical properties.
Oxygen (O), Sulfur (S), and Selenium (Se) have 6 valence electrons each. They will have the similar chemical properties.

How will the ice water mix with the salty water? Write your hypothesis below.
Answer:
See below.
Explanation:
The actual reason that the application of salt causes ice to melt is that a solution of water and dissolved salt has a lower freezing point than pure water. Ice in contact with salty water therefore melts, creating more liquid water, which dissolves more salt, thereby causing more ice to melt, and so on.
Answer: I think that the ice will go slower because salt slows down the rate of which Its melt, so the ice would last longer

What trend do you notice about the relative amount of carbon dioxide in the atmosphere over time? And for oxygen? What factors could cause changes in the carbon dioxide and oxygen gas levels of Earth’s atmosphere?
Answer:
The proportion of oxygen went up because of photosynthesis by plants. The proportion of carbon dioxide went down because: it was locked up in sedimentary rocks (such as limestone) and in fossil fuels. it was absorbed by plants for photosynthesis.
Explanation:
Due to plant photosynthesis, the amount of oxygen increased. Because carbon dioxide was trapped in sedimentary rocks (like limestone) and fossil fuels, its percentage decreased. Plants utilized it for photosynthesis.
What is photosynthesis?Carbon dioxide concentrations CO2 are expected to rise, which will raise serious concerns about how plants react to the gas. Increased photosynthesis results from elevated CO2 in plants, which increases biomass and carbohydrate production.
It varies both within and across species as to which organ receives the extra carbs. There is currently a paucity of knowledge regarding how the greater concentration of carbohydrates generated under rising CO2 affects the sugar sensing and signaling pathways of plants.
Therefore, Due to plant photosynthesis, the amount of oxygen increased. Because carbon dioxide was trapped in sedimentary rocks (like limestone) and fossil fuels, its percentage decreased. Plants utilized it for photosynthesis.

Gigantism is an extreme situation this is almost usually due to an adenoma, a tumor of the pituitary gland. Gigantism happens in sufferers who had immoderate boom hormones in childhood. The pituitary tumor cells secrete an excessive amount of boom hormone (GH), which main to many adjustments withinside the body.
How is gigantism diagnosed?
If gigantism is suspected, the prognosis is commonly shown via way of means of taking blood assessments to degree the stages of boom hormone and insulin-like boom component 1 (IGF1) circulating withinside the blood. IGF1 is launched into the blood often via way of means of the liver in reaction to boom hormone.

Explain why you think blood vessel radius can have a larger effect on the body than changes in blood vessel length (use the blood flow equation).
Here is your Answer:-
✓ While the flow rate is proportional to the length, the flow rate is proportional to the fourth power of the radius.
Blood vessel da\iameter affects the blood pressure in body because it creates vasoconstriction and vasodilation, hence blood vessel radius has a larger effect on the body.
What is the effect of blood vessel radius in the body?Blood flow increases considerably when the radius of the vessel lumen grows (a process known as vasodilation), and vice versa.
Vasodilation causes the blood vessel width to increase, making it easier for the heart to pump blood into it. However, such a blood artery has lower blood pressure than a smaller diameter or vasoconstriction blood channel.
Arterioles have the greatest increase in resistance and the greatest drop in blood pressure. Arteriole constriction increases resistance, resulting in a drop in blood flow to downstream capillaries and a bigger decrease in blood pressure.
Therefore due to blood pressure in body blood vessel radius affects larger.

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.

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.

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

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.
