Answer:
natural selection
Explanation:
According to the evolutionary theory, natural selection can be understood as the process of differential survival and reproduction of individuals due to phenotypic differences, which may be associated with different colors, sizes, behaviors, etc. The only prerequisite is that these phenotypic differential traits must be heritable, which means that they must be passed by genes from one generation to the next. For example, in the white-throated sparrow, it has been discovered two morphs that differ in behavior due to a chromosomal inversion in sex chromosomes.

How is mRNA or protein synthesis in general related to communication?
Answer:Three general classes of RNA molecules are involved in expressing the genes encoded within a cell's DNA. Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein synthesis. In eukaryotic cells, each class of RNA has its own polymerase, whereas in prokaryotic cells, a single RNA polymerase synthesizes the different class of RNA. Other types of RNA also exist but are not as well understood, although they appear to play regulatory roles in gene expression and also be involved in protection against invading viruses.

After a forest fire what would be the first change in a forest?
Pioneer species are established
A climax community is established
Wind carries seeds to the area and plants grow from these seeds
New soil forms from rock
c because
The first plants to move into the new bare ground after a wildfire are wildflowers or “weeds.” These fast-germinating, leafy herbaceous plants are also known as “forbs” or “ephemerals.” They quickly germinate, grow and produce a new crop of seeds.
Answer:
Pioneer species are established
Explanation:
A forest fire would represent the process of secondary succession.
In secondary succession, the first stage is the growth of pioneer species. The soil still remains, so no new soil needs to be made.
This rich soil allows for pioneer species to grow in the forest.
What are the reactants of photosynthesis? carbon dioxide and hydrogen hydrogen, oxygen, and water light energy, water, and carbon dioxide oxygen and glucose
Answer:
Explanation:
glucose and oxygen (D)
The reactants of photosynthesis are light energy, water, and carbon dioxide. The correct option is C.
What is photosynthesis?Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.
Photosynthesis is crucial because it is the process by which plants convert carbon dioxide into oxygen using sunlight.
Animals require oxygen to survive, and plants serve as nature's air filter, filtering out harmful carbon dioxide.
Photosynthesis is the conversion of light energy by phototrophs into chemical energy, which is then used to power cellular activities. Sugars, which are formed from water and carbon dioxide, are used to store chemical energy.
Carbon dioxide and water are the photosynthesis reactants. Plants require carbon dioxide and water to produce food.
Thus, the correct option is C.

explain the relation between cell tissue organ and system
Answer: Animals and plants are made of cells. Tissues are made from cells of a similar type. Organs are made from tissues, and systems are made from several organs working together.
Explanation:
Answer:
In plants, just as in animals, similar cells working together form a tissue. When different types of tissues work together to perform a unique function, they form an organ; organs working together form organ systems.

How is co2 converted to glucose?
Answer:
Photosynthesis
Explanation:
Atmospheric carbon dioxide is converted to glucose during the Calvin-Benson cycle. This requires the overall reduction of CO2, using the electrons available from the oxidation of NADPH. Thus the dark reactions represent a redox pathway. NADPH is oxidized to NADP+ and CO2 is reduced to glucose.

Detailed information about the processes and tectonic plate interactions that are causing the volcanos to occur. Include an explanation of convection currents.
Answer:
Tectonic plates recurring over and over again cause a rupture in the Earth's crust. This agitates the magma in volcanoes, causing the volcano to erupt.
Explanation:
Answer:
These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.

What are the (exact) products and reactants for the electron transport chain in cellular respiration?
Answer:
Cellular respiration is the process responsible for converting chemical energy, and the reactants/products involved in cellular respiration are oxygen, glucose (sugar), carbon dioxide, and water. While the exact steps involved in cellular respiration may vary from species to species, all living organisms perform some type of cellular respiration. The equation for aerobic respiration shows glucose being combined with oxygen and ADP to produce carbon dioxide, water, and ATP
Explanation:
How are photosynethis and cellular respiration similar? And how are they different ?
Answer:
Photosynthesis, carried out by sunlight-reliant producers, requires carbon dioxide and releases oxygen and glucose, while cellular respiration (carried out by animals) requires oxygen and releases carbon dioxide and ATP. However, they both are biological processes that supply the organism in question with energy.
Explanation:
Answer:
The answer will be listed below.
Explanation:
The two processes, photosythesis and cellular respiration, are similar in that they both produce energy. These are ways for organisms to produce their food. Although, these two processes are completely different from each other. Cellular respiation occurs in all living organisms while photosythesis occurs only in phototrophs. Photosythesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into ATP, and then release waste products.
What is the name of a double layer of phospholipids (called lipid bilayer)?
The name of a double layer of phospholipids is called a lipid bilayer.
The lipid bilayer is a fundamental component of cell membranes and plays a crucial role in maintaining the integrity and function of the cell. It consists of two layers of phospholipids arranged in such a way that the hydrophobic (water-repellent) fatty acid tails are sandwiched between the hydrophilic (water-loving) phosphate heads.
This arrangement creates a barrier that controls the passage of substances into and out of the cell, allowing for selective permeability. The lipid bilayer also houses various proteins, cholesterol molecules, and other components that contribute to the overall structure and function of the cell membrane.
Thus, the correct option is lipid bilayer.
