Answer:
Plant species it eats
Explanation:
The 1st, 3rd, and 4th are describing its surroundings not the individual grasshopper.
<h2>J-shaped growth curve</h2>
Explanation:
- J- shaped growth curve A curve on a graph that records the circumstance wherein, in another condition, the population thickness of a living being increments quickly in an exponential or logarithmic structure, yet then stops unexpectedly as ecological opposition (for example regularity) or some other factor (for example the finish of the reproducing stage) unexpectedly gets compelling.
- Population numbers regularly show extraordinary variance, giving the trademark 'blast and bust' patterns of certain bugs, or the ones seen in algal sprouts.
- This kind of population development is named 'thickness autonomous' as the guideline of development rate isn't attached to the population thickness until the last accident
George is lifting weights. He starts by doing biceps curls
which involves flexing his
elbows. His elbow is able to bend
because the humero-ulnar joint is a hinge
joint. Sam is doing leg presses, extending his knees as he pushes
against the weights. Meanwhile, Jane is doing "lat pulls" by pulling
downward on a weighted bar. This movement involves adduction of her arms.
Her shoulder joint is a ball-and-socket joint, allowing
a wide range of movements.
Answer:
a. + glucose, + lactose = On
b. - glucose, - lactose = Off
c. + glucose, - lactose = Off
d. - glucose, + lactose = On
Explanation:
Lac operon has both types of control, repressible and inducible.
Whenever glucose level is low in the cell, an enzyme known as adenylyl cyclase raises the level of cAMP which forms a dimer with CRP protein and they both act as activator of lac operon and cause expression.
Apart from this, when lactose is present in the cell, β-galactosidase enzyme metabolizes lactose to form allolactose which causes allosteric repulsion in the lac repressor and causes its removal from the operator. As soon as repressor is removed lac operon gets activated.
In wild type lac operons, the expression of lac operon occurs when glucose level is low in the cell and lactose is present but in this mutant presence or absence of glucose will not make a difference because CRP will bind Plac promoter independent of cAMP level i.e. activator CRP will work even in high glucose concentration. If lactose is present then lac operon will always express so in option 'a & d' lac operon will express but in option 'b & c' it will not express.
Hmm.this one is complicated .many factors affect the amount of solar energy an area receives but mainly the length of the solar rays.places close to the equator are hotter because the rays are short and the travel less distance.but away from the equator the rays are longer
