They have long productive lives, cows will produce 10 or more calves calving regularly. The cows show great efficiency and often wean calves that weigh 45-50% of their body mass
Answer:
humanity has a 95% probability of being extinct in 7,800,000 years
Answer:
<u>50%</u>
Explanation:
<em>Since</em> it was not a case of a Lettuce seed exposed first to <em>red light</em> and then to <em>far-red light</em> which will very likely not germinate because Pr (chromoprotein inactive form) absorbs red light efficiently, the light absorbed will convert a high proportion of the molecules to the Pfr (chromoprotein active form), thereby inducing germination. So there is a 50/50 percentage chance of of germination.
Answer:
Disadvantages.
Explanation:
A big disadvantage of sexual reproduction is that the process is much slower than asexual reproduction. For starters, the cell division, which is meiosis, is more complex and has more stages than mitosis.
Answer: Enzyme compartment cannot be used as metabolic control mechanism.
Explanation: Metabolic control or regulation employs many substrates,enzymes and byproduct to send a signal to cells to perfom or stop perfoming certain duties. Too much glucose for instance will regulate, activate and send signals using insulin to store glucose in form of glycogen using the process of glycogenolysis. Hormones and enzymes will also signal to activate the process of sleep, menstruation, digestion etc activating and regulating different kind of cells.
On the other hand enzyme cormpartmentation is there to maintain order and protect cells from lysis by making sure that each enzyme and cell works in its own confined space.
