It is the “parent” generation, or the “paternal” one which the rest are observed from.
ECM is the extracellular matrix, or the set of extracellular molecules secreted by cells with the purpose to support surrounding cells. In plants the cell wall is the ECM and in mammals ECM can be in the form of fibrils and may constitute a significant portion of the bulk of the organism and it also referred as connective tissue.
Answer:
i think its vestigial, but if not then it is homologous.
hope that hepls!
Answer: diffusion
Explanation:
water is used many different ways in photosynthesis. if you know how diffusion works than that’s pretty much what waters job is. It’s part of the equation which is the cycle of a plants life. Hoped this helped
Answer:
1. Carbon is moving from the living things in the tank into the air when they respirate, and from the air back into plants via photosynthesis
2. The amount of carbon in living things is increasing as plants use the carbon in the atmosphere, and animals eat the plants.
Explanation:
According to the question, a well sealed tank contains air, plants and animals. Since light can get into the tank, plants can perform photosynthesis. Living things in the tank release carbon in form of carbondioxide (CO2) gas through respiration. Plants then make use of this carbondioxide (CO2) to synthesize carbon-containing food (glucose) in the presence of sunlight. This process is called PHOTOSYNTHESIS.
Animals eat those plants and the stored carbon in the plants gets transferred to them. The animals release this carbon into the air again in the form of carbondioxide when they respire. Hence, carbon in the tank moves from the living things (respiration) into the air and back into plants (photosynthesis).
2. Since the amount of carbon in the air is decreasing, the carbon is being used by the living things in the tank. Plants absorb the carbon in the atmosphere for photosynthesis, then animals eat the plants to get the carbon. Therefore, the amount of carbon in the living things is increasing.
