Lynn Margulis developed the endosymbiont theory to explain the evolution of certain eukaryotic organelles, such as chloroplasts and mitochondria. According to this theory, which of these events occurred to an ancient prokaryotic cell?

Answers

Answer 1

Answer: Endosymbiosis theory suggests that eukaryotic cells emerge from prokaryotic cells.

Explanation:

Biologist Lynn Margulis was the first person who studied the endosymbiosis in 1960. According to him the chloroplasts and mitochondria have been originated from ancient bacteria which was free living. These organelles are found in eukaryotic cells. The chloroplasts are found in plant cells and they have a green pigment called as chlorophyll which helps in the process of photosynthesis by absorbing the sunlight energy. The mitochondria produce energy in the form of ATP by the biochemical oxidation of the food.

The main source of energy for both plants and animals is
A. water
B. fertilizer
C. glucose
D. carbon dioxide

Answers

Answer:

None of the above.

I'm pretty sure the Sun is the main source of energy.

Explanation:

Here is what I found:

Energy from the sun is the primary source of energy for the earth's ecosystem. The sun's energy is collected and processed by plants through photosynthesis and converted into food for animals. Without the sun, animals would not exist. Food is stored energy and essential elements like carbon, nitrogen and hydrogen.

The main source of energy for both plants and animals is glucose. Therefore, the correct option is option C.

The process of photosynthesis, which plants use to transform solar light energy into chemical energy, makes plants one of a kind. Here, plants use the energy from sunlight to change water and carbon dioxide into glucose, a simple sugar, and oxygen. Plants require glucose as a vital source of chemical energy in order to grow, reproduce, and perform other metabolic functions. The majority of life on Earth gets its energy mostly from this conversion of solar energy into chemical energy. On the other hand, sunlight cannot be used by animals as a direct source of energy. They instead rely on eating plants or other animals to meet their energy needs.

Therefore, the correct option is option C.

A motorcycle weighs 2,009 newtons. The mass of the motorcycle is
kilograms. Use g = 9.8 N/kg for gravity.

Answers

Answer: 2009 N / 9.8 N/Kg = 205 Kg.

The mass of the motorcycle is approximately 205 kilograms.

Mass refers to the amount of matter in an object, and it remains constant regardless of the location (e.g., on Earth or in space).

Mass (kg) = Weight (N) / Acceleration due to gravity (N/kg)

Given that the weight of the motorcycle is 2,009 newtons and the acceleration due to gravity is 9.8 N/kg, we can calculate:

Mass (kg) = 2,009 N / 9.8 N/kg ≈ 205 kg

So, the mass of the motorcycle is approximately 205 kilograms. The weight of an object is the force with which it is pulled towards the Earth due to gravity. In this case, the motorcycle weighs 2,009 newtons, which means it experiences a force of 2,009 newtons due to the gravitational pull of the Earth.

Amino acids, long considered simply substrates for protein synthesis, have been recently shown to act as modulators of intracellular signal transduction pathways typically associated with growth-promoting hormones such as insulin and insulin-like growth factor-1.

Explanation:

The correct tRNA with the anticodon (complementary 3 nucleotide sequence UAC) binds to the mRNA using the ribosome. This tRNA delivers the correct amino acid corresponding to the mRNA codon, in the case of the start codon, this is the amino acid methionine.
