Explanation:
Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. And the parts of the brain involved in motor control lose cells over time.
Researchers found that the brain's response time begins to decline at age 24. The descent is a slow, but nonetheless, steady one.
Answer: d. The ecosystem reached its carrying capacity, and was not able to support continued population growth.
Explanation:
The carrying capacity can be defined as the maximum population size of the species that habitat or ecosystem can support or sustain on the basis of availability of food, water and other necessities. This is an important factor which keeps a balance of the population of a species in a particular region or ecosystem.
On the basis of the above information, The ecosystem reached its carrying capacity, and was not able to support continued population growth is the correct option to level off the rising populating of the birds.
Answer:A=V
Explanation:
It is used to move small or non polar molecules does not apply to facilitated diffusion. Small, non-polar molecules can diffuse directly across the phospholipid bilayer.
There are 3 sources of energy, which are also known as macronutrients ,carbohydrates, protein, and fat.
Of these three, carbohydrates are the body’s preferred source of energy. Carbohydrates break down into glucose, which is an immediate source of energy especially for the brain and muscles. The macronutrient proportions recommended for general, healthy diet are: 45-65% of energy (or calories) from carbohydrates, 10-20% of energy (or calories) from protein and 20-35% of energy (or calories) from fat.
