Answer:
Products of photosynthesis are used in cellular respiration
Explanation:
Photosynthesis is a process performed by the plants (also some algae and bacteria) in which the energy of sunlight is transformed into chemical energy usable by those plants. Necessary components of this set of reactions are sunlight, water and CO2, while resulting products are glucose and oxygen. Products of photosynthesis are then used in the metabolic processes known as cellular respiration. During the cellular respiration, glucose and oxygen are used for the production of ATP, CO2 and water. Cellular respiration is performed in mitochondria of all living organisms.
Photosynthesis occur in the chloroplast, membrane organelles with photosynthetic pigments (such as chlorophyll).
Joint Firs are the plants in which division can live as long as 1500 to 2000 years.
Answer:
IN OLDEN TIMES:
A girl, when she reaches puberty is barred from entering the prayer room or performing any religious prayers during her menstruation. The only reason mentioned in our scriptures is that she is (ashudha) unclean during that period.
During ancient days, women would take bath in the river, pond or near the well. During the time when the girl would be menstruating, it would be awkward to bathe outside in the river as it would probably ‘pollute’ the water.
So, the ladies did not take bath. Since the ladies did not take bath, they were naturally termed ‘unclean’ during that time. Hence, their being barred from the clean’ places in the house, namely the prayer room or the kitchen.
However, Science has a different meaning for the menstruation. As per science, a woman is more irritable during those days because of a hormonal imbalance. Psychics claim that there is a different aura around a menstruating woman, maybe again a chemical reaction.
Segregating to pray requires a positive attitude and people tend to respond to the negative virations of a person standing with you; maybe that was the reason why a woman was barred from public places and the kitchen.
TODAY:
Times have changed,
It is the old saying of old people. But of a girl cooks during periods then it is not to become bad in taste or it won't get spoiled. The taste of food is going to be same as she cooks on other days. So I think this saying is wrong and girls can cook during their mensuratl days. It is a natural cycle and they r not responsible for it
the . answer to this question is b They had food sources that were low to the ground
Answer:
The correct option is <em><u>A. Over time, due to evolution by means of natural selection, resistant weeds survived, reproduced, and passed on their herbicide resistant genes. </u></em>
Explanation:
Herbicides can be described as substances which are used to kill unwanted plants such as the weeds. Nowadays, selective herbicides are produces which are effective in killing the weed species and do not harm the crop plants.
But over time, the weeds get resistant to the herbicide. As the theory of natural selection says, 'survival of the fittest', the herbicide which are resistant are better adapted to live hence, they pass their genes to the offsprings. This results in the production of more herbicide resistant weeds.
