Cell organelles are the subparts in a cell. Organelles are the microscopic structures.
Organelles in the cells are ultra-structures that can be visualized with the help of specialized microscopes.
Cell organelles help in performing various functions in the cell thus exhibiting division of labour.
Some of these organelles and their functions are as follows:
Nucleus – It regulates all the cellular activities. It is the control centre of a cell.Lysosomes – Lysosomes contain many digestive enzymes. It function is to degrade dead or worn out cell.Centrioles – Centrioles are present only in animal cells. It frames the cell’s skeleton and helps in cell division.Cytoplasm – It is fluid in nature and forms the matrix. It acts as a medium for many cellular reactions.Cell membrane – It is made up of proteins and lipids. It controls the movement of molecules in and out of the cell.Mitochondria – It helps in the production of energy in the form of ATP moleculesTherefore, cell organelles are important for maintaining cell structure and function.

The types of Fossils are :
Body Fossils.Molecular Fossils.Trace Fossils.Carbon Fossils.Pseudo FossilsFossilsThe importance of fossils are :
Fossils give important prove for advancement and the adjustment of plants and creatures to their situations.
Fossil prove gives a record of how animals advanced and how this handle can be spoken to by a 'tree of life'.
The types of Fossils are :
1) Body Fossils-
Body fossils were parts of the life form, such as bones or teeth
2) Molecular Fossils-
Molecular fossils are natural atoms determined from once living organisms. Body fossils were parts of the life form, such as bones or teeth.
3) Trace Fossils-
Trace fossils incorporate foot impressions, eggs, burrows, and fertilizer.

1. The carbon cycle is complex. When we breathe, we inhale some CO2, but
that CO, does not stay in our bodies. Explain how the carbon atoms in the
molecules of your body got there, indirectly from the air. How did the C get from
the air into us?
Explanation:
The carbon dioxide breathed out is a by-product of the process of cell respiration, as is water. In this process, energy is produced in the mitochondria of cells. This energy is our physical "life force". Both oxygen and glucose are required for this. Glucose contains carbon. That's where the carbon in carbon dioxide comes from. Glucose plus oxygen produces carbon dioxide, water and energy. When this process stops, the cell dies.
the amount of carbon dioxide in the atmosphere has been increasing. if this trend continues, what will happen to the temperature of the atmosphere?
Answer:
The temperature will increase in the climate
Explanation:
When more carbon dioxide in the air it will cause greenhouse effect, rising the temperature in the atmosphere.

Which statement accurately describes the role of key organelles in energy transfer
Answer:
Energy is captured and stored in the chloroplast and released in the mitochondria.Explanation:
The statement that accurately describes the role of key organelles in energy transfer is Mitochondria.
The organelles are specialized structures present in the cells and they perform various functions to keep the cell alive.
Organelles perform particular functions to keep a cell alive in the same way that organs perform specific roles to keep an organism alive.
The organelles responsible for energy transfer in the cell are Mitochondria.
Mitochondria are organelles in cell that provide the majority of the chemical energy required to fuel the cell's metabolic processes.
The key role of mitochondria is energy transfer which occurs in Oxidative Phosphorylation. Oxidative Phosphorylation produces ATP (adenosine triphosphate) by employing the energy liberated during the oxidation of the food we consumed.
Therefore, we conclude that the statement that accurately describes the role of key organelles in energy transfer is Mitochondria.

A deletion can cause the reading frame of the codons
to change affecting many amino acids of the protein
An insertion can cause the reading frame of the
codons to change affecting many amino acids of the
protein
A substitution can cause the reading frame of the
codons to change affecting many amino acids of the
protein
Answer:
I think its B because An insertion changes the number of DNA bases in a gene by adding a piece of DNA. As a result, the protein made by the gene may not function properly. But it could be C because Missense mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene.

What causes ocean water to be colder at the poles than at the equator?
A. Sunlight hits at an angle, so the warmth is spread out.
B. Sunlight hits directly, so the warmth is more concentrated.
C. Cold water currents move from the poles to the equator.
D. Seasonal winds push warm water away from the coasts.
The ocean water is colder at the poles than at the equator because
Cold water currents move from the poles to the equator.
What is an equator?
An equator a line imaginably drawn on the earth equidistant from the poles, dividing the earth into northern and southern hemispheres and constituting the parallel of latitude 0°.
The Equator is a circle of latitude, about 40,075 km in circumference, that divides Earth into the Northern and Southern hemispheres. In other words, The Equator is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles.
Locations on the equator experience the shortest sunrises and sunsets because the Sun's daily path is nearly perpendicular to the horizon for most of the year.
What are poles?Poles are the points where the earth’s imaginary axis of rotation intersects the earth’s surface and where the meridians converge.
The north pole is located in the northern hemisphere, in the central part of the Arctic Ocean. The south pole is located in the southern hemisphere, on the continent of Antarctica.
North and South poles are also defined for other planets or satellites in the Solar System, with a North pole being on the same side of the invariable plane as Earth's North pole.
Relative to Earth's surface, the geographic poles move by a few meters over periods of a few years. This is a combination of Chandler wobble, a free oscillation with a period of about 433 days; an annual motion responding to seasonal movements of air and water masses
