It occurred during meiosis.
just took the test, hope this helps:)
Answer:
When the patch occupancy rate (c) equals the patch extinction rate (e), patch occupancy (P) is 0
Explanation:
According to Levin's model (1969):
<em>dP/dt = c - e</em>
where P represents the proportion of occupied patches.
<em>c</em><em> </em>and <em>e </em>are the local immigration and extinction probabilities per patch.
Thus, the rate of change of P, written as dP/dt, tells you whether P will increase, decrease or stay the same:
- if dP/dt >0, then P is increasing with time
- if dP/dt <0, then P is decreasing with time
- if dP/dt = 0, then P is remaining the same with time.
The rate dP/dt is calculated by the difference between colonization or occupancy rate (<em>c</em>) and extinction rate (<em>e</em>).
c is then calculated as the number of successful colonizations of unoccupied patches as a proportion of all available patches, while e is the proportion of patches becoming empty. Notice that P can range between 0 and 1.
As a result, if the patch occupancy rate (c) equals the patch extinction rate (e), then patch occupancy P equals to 0.
Answer:
<h2>B) 4, 6, 7, 1, 2, 3, 5</h2>
Explanation:
Action potential ,the change in electrical potential associated with the passage of an impulse along the membrane of exciting cell. The order of steps in generation of action potential is-4.A graded depolarization brings an area of an excitable membrane to threshold.→ 6. in excitable membrane ,after that, Sodium channel get activated,→ 7. aftre that Sodium ions enter the cell and depolarization occurs,→1.after that, then Sodium channels are inactivated,→ 2. Voltage-gated potassium channels open and potassium moves out of the cell, initiating repolarization, →3. Sodium channels regain their normal properties,→ 5A temporary hyperpolarization occurs.
Structural adaptations are biological characters of an organism like the bill on a bird or the fur on a bear. Other adaptations are behaviour.
<h3>Define adaptation?</h3>
Adaptation, the method by which a species becomes adapted to its surroundings; it is the outcome of biological selection's acting upon heritable divergence over various generations.
Thus,Structural adaptations are biological characters of an organism like the bill on a bird or the fur on a bear.

#SPJ1
He wanted to see how different traits passed through the pea plants he grew. To do this, he needed to cross polliante so that their were multiple parents affecting the genes of the new pea plant. If he self pollinated, all the new baby pea plants would Look the same as their parents and we wouldn't know as much as we do about genetics now
