Answer:
In plants photosynthesis occurs in two steps light-dependent stage and light-independent stage.
ATP is energy carrier and NADPH is electron carrier and both are produced during the first step from the sunlight as they carry the energy and electron to the next step which is light-independent step. In this step both ATP and NADPH are used in the formation of sugars from carbohydrates.
Therefore, these molecules connect the light-dependent and light- independent reactions of photosynthesis.
Answer:
Differentiation of heterochromatin and euchromatin decreases
Answer:
The specific distant organ which is affected by a specific hormone secreted by a endocrine gland is called the target organ. For example, oxytocin secreted by the posterior pituitary affects the contraction of the walls of uterus resulting in parturition. Here, the uterine wall is the target organ.
Explanation:
- Endocrine system is a system of ductless glads that secrete and pour chemical messengers into the blood and control various metabolic activities of the body.
- Hormones are signal molecule that are produced by endocrine gland and are directly poured into the blood.
- According to current scientific definition : Hormones are low molecular weight, chemically heterogeneous non-nutrient substances which produced in trace amounts and act as inter-cellular signal molecules.
- Even though blood distributes hormones throughout the body, only specific target cell can respond to each hormone because only the target cell have receptors for binding with particular hormone.
percolation maybe. percolation in the water cycle would be when the water soaks into the ground and joins the groundwater.
