Stomata. Abscisic acud is releases in exrreme conditions when water conservation is more important that water loss amd so stomatal pore closes when ABA gets attached to receptors on membrane of guard cells
Answer:
Yes, the biotechnology are associated with the genetic engineering as, the genetic engineering are the direct modification or manipulation of the organism which are using the biotechnology.
Basically, it the set of technologies which are used to modify the genetic cells including the transferring of the genes across the boundary to produced the organism. And with the help of biotechnology, new DNA are obtain by copy the genetic material by using the methods of DNA.
Answer:
Independent variable: varying amounts of light
Dependent variable: plant growth
Explanation:
The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.
The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
Answer:
Transpiration
Explanation:
Plants lose gallons of water every day through the process of of transpiration
Answer and explanation;
Contraction of skeletal muscles;
-An action potential from a motor neuron triggers the release of Ca2+ ions from the sarcoplasmic reticulum.
-Calcium ions expose the myosin heads by binding to a blocking molecule (troponin complexed with tropomyosin) and causing it to move.
-The myosin heads form a cross-bridge with actin binding sites.
-ATP binds to the myosin heads and breaks the cross-bridge.
-The hydrolysis of ATP causes the myosin heads to change shape and swivel - this moves them towards the next actin binding site.
-The movement of the myosin heads cause the actin filaments to slide over the myosin filaments, shortening the length of the sarcomere.
-Via the repeated hydrolysis of ATP, the skeletal muscle will contract.
