Natural gas may also be produced from organic material at high enough pressure. The two basic factors that convert biological matter into fossil fuels are heat and pressure.
What transforms extinct animals into crude oil and natural gas?Algae and plants inhabited shallow oceans millions of years ago. The organic material was buried when it perished and sank to the bottom, where it mingled with other materials. The remnants of these animals were converted into fossil fuels over millions of years under extreme pressure and heat.
Layers of clay and sand have been covering dead creatures that were buried in the water millions of years ago. These decomposing organisms became petroleum and natural gas as a result of the lack of air, the high temperature, and the high pressure.
Only carbon and hydrogen are necessary for the conversion of organic matter (OM) into petroleum.

If a coil is placed in pure water (0% concentration), using osmosis describe what will happen. Keep in mind there are concentrations of solutes in cells
Red blood cells will osmotically absorb water from a solution (such as pure water) that has a greater water concentration than their contents, swell up, and rupture. A higher concentration of water outside the cell will diffuse into a lower concentration of water inside the cell.
What impact does water concentration have on osmosis?Osmosis happens when there is an inverse relationship between the concentration of solutes and the gradient in water concentration across the membrane. Osmosis continues to take place until the water concentration gradient is zero or the hydrostatic pressure of the water equals the osmotic pressure.
An animal cell would swell and explode if it were put in a drop of 100 percent pure water. This would occur because osmosis is permitted by the semi-permeable nature of the cell membrane.
At normal pressure and temperature, the water potential of pure water is always assumed to be zero. The kinetic energy that water molecules contain may be used to explain it.

A.The temporal lobe of the cerebrum
B.The temporal lobe of the cerebellum
C.The occipital lobe of the cerebrum
D.The occipital lobe of the cerebellum
Answer: C
Explanation:
The occipital lobe is one of the four major lobes of the cerebral cortex and it sits at the back of the brain, therefore at the back of the head.
so the answer is C. The occipital lobe of the cerebrum
The occipital lobe of the cerebrum is located at the back of the head. Therefore, option C is correct.
The occipital lobe is located at the back of the head and is part of the cerebrum, which is the largest and most highly developed part of the brain. The occipital lobe is primarily responsible for processing visual information, including visual perception, interpretation of images, and color recognition.
It plays a crucial role in vision and is situated at the posterior (back) region of the cerebrum. It also contains the primary visual cortex, which is responsible for the initial processing of visual stimuli received from the eyes.

Read each example and decide what the resulting effect on the gene pool of that population would be.
A zebra migrates to join a different herd of zebras.
Competition for sunlight leads to taller trees.
The DNA of a snake changes to make its venom stronger.
A grassfire randomly sweeps through a population of buffalo
and kills most of the animals.
Being a migratory mammal, the zebra moves to several herds as it acquires newer alleles from other populations.
Taller trees result from the fight for sunlight, which may benefit particular alleles. New alleles may be produced from DNA when a snake's DNA is altered to make it deadly. Buffalo rushed across the grass, picking random alleles.
What impact do changes in a population's gene pool have?The size of a population's gene pool is assumed to have some bearing on its capacity for adaptation and evolution. For instance, a population's potential for future adaptability to shifting environmental conditions may be increased by a broad and diversified gene pool.
Genetic variety can be increased by new genes and alleles being created as a result of gene duplication, mutation, or other events.
When individuals leave their family unit or herd to join other populations, this is known as gene flow in animals. New alleles are introduced into populations when people move in and out.

i have to make a model for class and i don’t understand anything i have to do, can anyone help me complete the model?Part 2 and 3.
Answer: I think maybe you could make an illustration about the process of photosynthesis and cellular respiration. Maybe you could print some images like the sun, leaves, and molecules. In the molecules like oxygen, carbon dioxide, water, you could just make small circles. You can put it all together by adding arrows to show the next step of the process.
2. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP. Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. The bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds. Carbon dioxide and water are created as byproducts. This process occurs in mitochondria.
3. In the two processes, we can see that the products of one process are reactants of another – and vice versa. Glucose and oxygen – which happen to be the products of photosynthesis, are required to facilitate cellular respiration, while carbon dioxide – which is a by-product of cellular respiration, is required to facilitate the process of photosynthesis.
