which structure is found in the cytoplasm of a prokaryotic cell
Answer:
By definition, prokaryotes lack a membrane-bound nucleus to hold their chromosomes. Instead, the chromosome of a prokaryote is found in a part of the cytoplasm called a nucleoid. Prokaryotes generally have a single circular chromosome that occupies a region of the cytoplasm called a nucleoid.

5. Which process usually results in offspring that exhibit new genetic
variations?
Answer:
It's the first choice that is fertilization
The process that usually results in offspring that exhibit new genetic variations is known as fertilization. Thus, the correct option is 1.
What is Genetic variation?Genetic variation may be defined as the occurrence of differences in sequences of genes between individual organisms of a species. The most prominent causes of genetic variation are mutations, sexual reproduction, gene flow, genetic drift, etc.
The first option describes the process of successful fertilization between male and female gametes. Thus, this sexual reproduction is the most characteristic process of inducing genetic variations among individuals of the same species.
The option third illustrates the process of budding in hydra, and the option reveals the process of binary fission in amoeba. Both are types of asexual reproduction in which the offspring is produced by a single parent only. And hence, they produce identical types of offspring without much genetic variations.
Therefore, the process that usually results in offspring that exhibit new genetic variations is known as fertilization. Thus, the correct option is 1.

What is evolution? How can evolution be scientific when no one was there to see it happen?
Answer:
Evolution is looking back and using scientific inference to make a timeline on adaptation of a species over time.
Explanation:
Looking at skulls, skeletal remains and carbon footprints left behind, we can compare and date remains of early humans and other species from years ago and compare them to late and modern remains. Thus making a timeline and showing the slow evolution of our adapting species.

How does nuclear fusion make life on Earth possible?
A. creates the sun’s magnetic field
B. blocks radiation from reaching Earth
C. releases energy that warms Earth
D. creates Earth’s magnetic field
Answer:
C
Explanation:
Nuclear fusion is the process by which the Sun produces its energy. It converts mass into energy, which is radiated over most of our solar system. The pressure from the fusion reactions keeps the star from collapsing.
Without the Sun's energy, in the amount we receive, the Earth would likely be entirely frozen and beyond deathly cold. Take Pluto as an example :)
Nuclear fusion make life on Earth possible by releasing energy that warms Earth.
SIGNIFICANCE OF THE SUN:
The sun is the ultimate source of energy needed directly or indirectly by every living organism on Earth. Sun provides the energy which autotrophs use to synthesize food.HOW DOES THE SUN GET ITS ENERGY?
The sun, which is a giver, however, also requires energy to do the needful. The sun gets its energy from a process called NUCLEAR FUSION, which is the coming together of the nuclei of two atoms.Nuclear fusion generates a large amount of energy for the sun when it occurs. This energy is used by the SUN, whose life on Earth is dependent on.Therefore, nuclear fusion make life on Earth possible by releasing energy that warms Earth.

Sulfur dioxide is considered a serious air pollutant. SO2 emissions that lead to high concentrations of SO2 in the air generally also
lead to the formation of other sulfur oxides (SOx). SO, can react with other compounds in the atmosphere to form small particles, and
these particles contribute to particulate matter (PM) pollution. Small particles may penetrate deeply into the lungs and in sufficient
quantity can contribute to health problems. Which of these is NOT a source of SO2 pollution?
A)
manufacture of cement
B)
extracting metal from ore
