Answer: when conditions for survival are unfavorable
Since there is two organism involved, sexual reproduction also increase the genetic variability of the population. This makes the population could adapt in wide condition. When the condition of the habitat changes and make survival is harder for general population, there might be someone with genetic variability that become favored instead.
Answer:
Locomotion is essential for various internal and external bodily functions
Explanation:
Locomotion is the art through which our body exhibit various functions and also escapes various condition of environment.
For instance –
a) Through movement of limbs, actions such as running, walking, jumping, crawling, swimming, etc are performed.
b) Movement of body parts and joints helps in taking different comfortable postures.
c) Even some body parts move even when it is not essentially vital for the function being performed such as movement of eyeball and external ear while swallowing food.
d) Movement of nutrients and blood with in the circulation system and digestive system.
e) Movement of sense organs when exposed to extreme environmental conditions.
Answer:
Co-variation between variables
Explanation:
Based on the scenario being described within the question it can be said that this scenario demonstrates the Co-variation between variables. This refers to the measure of how much two seemingly random variables vary together as opposed to separately which would otherwise be variance. Which explains why when one variable changes in value the other changes in an un-correlated way.
NADH and FADH2 are necessities in the electron transport chain because they power the chain by moving electrons into it.
NADH and FADH2 are both generated at the initial stages of respiration (the Kreb's cycle), a process during which food materials are broken down to generate energy. NADH is generated from NAD+ as a result of the addition of electrons while FADH2 is generated from FAD also due to the addition of electrons.
Once generated, both compounds get transferred into the innermost membrane of the mitochondrion where they travel down the electron transport chain, donating their electrons in the process and creating an electrochemical gradient to generate ATP.
Without NADH and FADH2, there will not be electrons to power the electron transport chain and the generation of ATP would become impossible.
