Answer:
Binary fission is a type of asexual reproduction, and /or rather an asexual reproduction common in most prokaryotes.
This function happens when the organism divides itself producing another replica of its genetic material and now altogether as the organism itself.
B. Small Veins
C. Lymph vessels
D. Heart atria
Blood normally flows from the capillaries directly into Small Veins. Thus, option B is correct.
The Small varicose veins called spider veins show up as thin, wavy lines directly beneath the skin. They typically afflict women and are particularly prevalent on the face and legs.
Blood pooling in veins close to the skin's surface causes spider veins. Venules, which are incredibly tiny blood channels, link the capillaries and veins throughout the body.
The venules play a crucial role in transferring blood from the capillaries to your veins that is depleted of oxygen and contains trash. The blood can return to the heart from that point on.
Therefore, option B is correct.

Fossil fuels are made from decomposed plants and animals found in the Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil and natural gas are examples of fossil fuels.
A fossil fuel is defined as a hydrocarbon consisting of naturally occurring material in the Earth's crust from the remains of dead plants and animals that is extracted and burned as a fuel. The main fossil fuels are coal, oil and natural gas.
The four main types of fossil fuels are
1. Petroleum
2. Coal
3. Natural gas
4. Oil emulsions.
They normally have a variety of physical, chemical and other essential properties. The most unfair thing about fossil fuels is that they are not green. Fossil fuels are made from plants and animals that decompose.
Thus, fossil fuels are made from decomposed plants and animals found in the Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil and natural gas are examples of fossil fuels.

Fossil fuels, like coal, oil, and natural gas, are the primary sources of energy for electricity generation, transportation, heating, and industrial processes, but their use also poses environmental challenges.
The relationship between fossil fuels and energy is foundational to modern society. Fossil fuels, including coal, oil, and natural gas, serve as the primary sources of energy for many aspects of our daily lives and industrial processes. Here's how this relationship works:
1. Energy Generation: Fossil fuels are burned in power plants to generate electricity, which powers homes, businesses, and industries. They are also used as fuels in vehicles, airplanes, and ships for transportation.
2. Heating and Cooling: Fossil fuels are essential for heating homes, providing hot water, and running HVAC systems, ensuring comfort and warmth in colder climates.
3. Industrial Processes: Many industrial processes rely on fossil fuels for heat, steam, and electricity, including manufacturing, chemical production, and refining.
4. Electricity Grid: Fossil fuels play a crucial role in stabilizing the electricity grid, providing reliable power during peak demand.
However, the extensive use of fossil fuels also has environmental consequences, including air pollution, greenhouse gas emissions, and climate change.
As a result, there is a growing emphasis on transitioning to cleaner and more sustainable energy sources like renewable energy (e.g., solar, wind, and hydropower) to mitigate these environmental impacts and ensure a sustainable energy future.

Answer:
Answered below
Explanation:
Birds and mammals have a double circulatory system and a four-chambered heart which separates the oxygenated blood and the deoxygenated blood from each other in the heart. This system of circulation is necessary to serve the high energy needs of the mammals and birds.
In this system, deoxygenated blood from the body passes through the superior and inferior Vena Cava into the right atrium. From the right atrium it flows into the right ventricle. From the right ventricle, it is then pumped into the pulmonary artery to be carried to the lungs. In the lungs, the deoxygenated blood is oxygenated and returned to the heart through the pulmonary veins.
Oxygenated blood enters the left atrium from the lungs through the pulmonary veins. It then moves into the left ventricle. In the left ventricle, it is then pumped into the aorta. The aorta is a large vessel that runs the length of the vertebral column, branching off to be circulate blood in the body system.

Answer:
Abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.
Biotic factors, can be described as any living component that affects another organism or shapes the ecosystem.
Answer:
An abiotic factor is a nonliving physical and chemical composition of nature. An biotic factor is a living organisms that shapes an ecosystem.
