Answer:
Gravity.
Explanation:
Gravity is what causes stuff to fall. It also keeps us on the ground, If there were no gravity, life wouldn’t exist as we know it today. Brainliest please! I need brainlest in order to keep answering questions!!
Hi!
The correct option would be A. There's lower biodiversity among birds
Biodiversity refers to the variety of organisms (species) that inhabit a particular place, such as in our case different species of birds.
From the graph we can see that over time, the bird species are declining. From roughly 1700 bird species, the number has fallen to about 200 bird species by the middle of the fourth year.
Hence, we can deduce, and it would be accurate to say, that there is a relatively lower biodiversity amongst the birds with regard to that in the beginning.
Option B is incorrect because if the birds had a higher reproductive rate, they would be able to make up for the loss of bird species from the habitat. From the graph, we can assume that there's a moderately low reproductive rate among the birds.
Option C is incorrect because we do not know the affect of this pollution on the producers (photosynthesizing plant lifeforms). It may be possible that they might be declining, but we cannot conclude that solely from the graph.
Hope this helps!
What six and seven please say me
Exercise is very vital to the body,it a form of physical activity.the sole aim of excercise is to maintain stamina, flexibility,keep fit and be overly healthy and well.
When we excercise, our heart rate increases and then it returns to the normal rate when with rest,when we take a break.there is reflection of vasoconstriction in the fingers as the blood is shunted to only the exercising muscles because it is noted that the pulse amplitude of the heart is always small after excercise and and increases slowly during recovery.
The amount of blood the heart pumps in a minute,that is the amount of blood ejected by the contraction of the left ventricle into systemic circulation increases when we are exercising and resistance to blood flow by skeletal muscles decreases.the blood vessels will try to adapt to the condition (exercise) inorder to control blood flow and as well meet energy demands.
When we finish exercising,our body temperature increases which will inturn cause increase in the pulse rate and the blood in our body makes way to our skin,hands and legs inorder to clear off the energy that was generated by the body(muscles) during exercise
