Electron and molecular geometry of a molecule matches when : The central atom has no lone pairs of electrons

The electron geometry of an atom is the various arrangement of the electrons in an atom while the molecular geometry of an atom is the 3D structure of atoms in a given molecule.

For the electron and molecular geometry to be the same the central atom has to possess no lone pairs of electrons.

Hence we can conclude that Electron and molecular geometry of a molecule matches when : The central atom has no lone pairs of electrons.

nucleus mitochondria and chloroplasts.

Answer:

1- Substance X is needed by the cell. If Substance X wasn't there then the cell may not be balanced out.

2-It depends. If the cell becomes larger then Substance Y will go into the cell; On the other hand if the cell shrinks or becomes smaller Substance Y will move out of the cell.

The feature of this ridge is Moraine, which is formed by the reformation of glaciers.

It is a type of erosion that leads to the formation of sediments in the shape of grains.

Moraine forms a ridge-like structure due to the gradual deposition and weathering of sand, stones, pebbles, and other compounds. Moraines are also found over the surface of glaciers in sheet form.

Therefore, the feature of this ridge is Moraine, which is formed by the reformation of glaciers.

Answer:

Free radicals are atoms or molecules with an odd (unpaired) number of electrons. They can be formed when oxygen interacts with certain molecules. Many free radicals are necessary for life and are used by our body's cells to kill invading bacteria.

Explanation:

A balance between free radicals and antioxidants is necessary for proper physiological function. If free radicals overwhelm the body's ability to regulate them, a condition known as oxidative stress ensues. Free radicals thus adversely alter lipids, proteins, and DNA and trigger a number of human diseases.

Answer:

1.cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

2.

Explanation:

Green leaves synthesize food woth the help of air, sunlight and water by a process called photosynthesis

3.Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.

THIS FOLLOWING ANSWER IS ONLY FOR QUESTION ONE:

      Cellular respiration is what cells do to break up sugars to get vitality they can utilize. Cellular respiration takes in food and employments it to create ATP, a chemical which the cell employments for energy. More often than not, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain. This produces ATP which supplies the vitality that cells have to be compelled to do work. When they do not get sufficient oxygen, the cells use anaerobic respiration, doesn’t require oxygen. In any case, this process produces lactic acid, and isn't as productive as when oxygen is utilized.

      Aerobic breath, the method that does utilize oxygen, produces much more energy and doesn’t create lactic acid. It too produces carbon dioxide as a squander item, which at that point enters the circulatory system. The carbon dioxide is taken to the lungs, where it is traded for oxygen. The rearranged equation for aerobic cellular respiration is:

[tex]C6H12O6 + 6O2 = 6CO2 + 6H2O + Energy (as ATP)[/tex]

DNA holds genetic information in the body

The type of evidence for common ancestry is genetics. The correct option is A.

The research of genes and inheritance. Genetic characteristics and qualities (such eye color and a higher likelihood of contracting a certain disease) are passed from parents to children through heredity.

Learning more about promoting health and preventing disease requires an understanding of genetic variables and genetic abnormalities.

The likelihood of having a kid with a birth defect, a developmental disability, or a condition like cancer or heart disease has been linked to several genetic abnormalities.

Since humans and chimpanzees share more than 92% of their DNA, this indicates that we are closely related and have a common ancestor. Genetics is the type of proof supporting this shared ancestry.

Thus, the correct option is A.

A - "Climate Change.

2.

Q - "What is the difference between a mass extinction and a regular (background extinction?"

A - ("Mass extintion involves many species over a short period of geologic time.)

3.

Q - "After the K-Pg mass extinction event, mammals were able to survive and proliferate. Which of the following factors contributed to this success the least?"

A - ("Most mammals being nocturnal, allowing them to see better in the darkened conditions.")

4.

Q - "How is climate change today similar to the major K-Pg extinction event that ended the reign of the dinosaurs?"

A - ("Individuals that can't adapt are dying, and species are going extinct.")

5.

Q - "Fossils provide evidence that best helps scientists determine changes over time in ____?"

A - ("the emergence or extinction of species.")

The major environmental change that is occurring today that could cause the next mass extinction is climate change, which is the last option as climate change is the major environmental change.

Climate change is caused by the increase of greenhouse gases in the atmosphere, primarily carbon dioxide from burning fossil fuels. This increase in greenhouse gases leads to global warming, which in turn causes changes in temperature and weather patterns around the world. These changes have significant impacts on ecosystems and can lead to the extinction of many species. Climate change can cause more frequent and severe extreme weather events such as droughts, floods, and hurricanes.

Hence, the major environmental change that is occurring today that could cause the next mass extinction is climate change, which is the last option as climate change is the major environmental change.
