Answer:
True
Explanation:
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
They're the smallest form of life on earth.
Answer:
Explanation:
Mitosis takes place in somatic cells of the body while the meiosis takes place in the germ cells. The mitosis is the equational division while the meiosis is reductional division.
The meiosis has 2 cell divisions i.e. meiosis I and meiosis II. The mitosis is a single division.
The pairing between the homologous chromosome/synapsis occurs in meiosis. It is not found in mitosis.
During the pachytene stage of meiosis, crossing over takes place. The homologous chromosome exchanges its genetic materials in crossing over.
In mitotic cell division, the chromatids do not exchange their genetic material.
The chromosome numbers are always the same as the parent cell in the mitotic division. In meiosis, the number of the chromosome turns to half of their parent cells.
There are 4 haploid chromosomes/tetrads forms at the end of meiosis. In meiotic division 2 chromosomes form from the parent cells.
Answer:
Reactants are gathered in chloroplasts.
Explanation:
Photosynthesis is a process unique to autotrophic organisms like plants. It is the process whereby plants use energy from sunlight to make their own food (chemical substance). The photosynthetic process occurs in two stages in the Chloroplast viz: Light dependent stage and light-independent stage.
In the light dependent stage, the plant captures energy from sunlight via its Chlorophyll pigment and uses it to break down water molecules (H2O) in a process called PHOTOLYSIS OF WATER. This process brings about the electrons and protons needed to form NADPH and ATP molecules respectively. This process occurs in the thylakoid membrane of the CHLOROPLAST.
In the light independent stage, also known as Calvin cycle, the plant uses the NADPH and ATP molecules produced in the light stage to reduce Carbondioxide (CO2), which enters through the stomata of the plant, and power the formation of glucose molecule (C6H12O6).
Hence, based on the steps listed by Jeremy for the photosynthetic process, the gathering of reactants (CO2, H2O and light energy) in the Chloroplast of the plant best classifies those steps.
