Earth could not have supported the lives or humans and other living things. There was no oxygen in the atmosphere, and Earth's surface was extremely hot
Answer:
Starch present in A and C, starch not present in B.
Explanation:
Photosynthesis is the process by which plants synthesise sugar.
This process requires light energy, carbon dioxide, and water, and produces sugar and oxygen. This sugar can be turned into starch.
In leaf B, the chemical that absorbs carbon dioxide would mean that there is none in the air for the plant to take in and use for photosynthesis, so it would not make sugar which can be converted to starch.
This is in contrast to C and A, where there is carbon dioxide present in the bag that can be used in photosynthesis.
The provided question lack the essential part which is required to answer the question, however the correct part is attached with with the question as image.
Answer:
From the provided punnett square it is clear that the genotype of parents are Rr for each. On this basis offspring which is maria that can be either RR, Rr, or rr. Maria have chances to get RR= 25%.
There can be no 100 surety of the phenotype of maria as there is 25% chances of rr and 75% of ability of tongue rolling.
to get Rr=50% and rr = 25%
Answer: Precipitation -> evaporation -> condensation
Explanation: precipitation is when it rains, so water is delivered by the atmosphere into the ocean. Evaporation happens when water in the ocean is heated up and returned to the atmosphere. Condensation occurs when water condenses due to pressure/temp differences creating clouds.
Cell wall and chloroplast are two examples of structures which are found in plant cells but not in animal cells.
