Answer: systemic veins and pulmonary arteries; pulmonary veins and systemic arteries
Explanation:
Based on what we have learned so far about the cardiovascular and respiratory systems, blood pH should be lower in the <u>systemic veins and pulmonary arteries</u> compared to the <u>pulmonary veins and systemic arteries</u>.
<u>Answer</u>: As the growth rate increases, the population size increases more rapidly. The slope becomes steeper.
An increasing growth rate means that more and more of the offspring will survive. Thus, this leads to a cumulative effect in which with an increasing growth rate, the slope becomes steeper.
If in the beginning only 1 out of 10 offspring will survive (r=0.1), then the population will increase with only one individual. However, if r=0.5 then 5 new individuals will be added. These in turn will be able to reproduce themselves with even higher r, which results in the cumulative effect mentioned above. The more individuals survive and the higher r, the faster the population size will increase.
No ecosystem is capable of sustaining such a growth for long periods of time. The population will reach and exceed a level called carrying capacity, which is the maximum number of individuals the ecosystem can sustain. Once this happens, the growth rate will be negative until the population size is once more under this level.
From now on, the population will vary around the carrying capacity with r switching from positive to negative in a continuous cycle. Furthermore, if this level is exceeded very much, then currently available resources will be consumed and thus the population size will plummet back to extremely low levels.
Locust swarms are a good example. The population size increases rapidly and devours all available food. If no more food can be found, then the majority of the individuals will die of starvation.
Answer: water is wet becuase thats how it was made and i don't know what happens when we die
Explanation:
Answer:
It is significantly easier to be infected with cutaneous anthrax as compared to other forms of anthrax.
Explanation:
LD50 is the lethal dose that can cause adverse effects and death. The LD50 of cutaneous anthrax is too low as compared to inhalation and gastrointestinal anthrax which means that only few Bacillus anthracis endospores can cause infection via cutaneous route while other routes require at least 200 times greater quantity to cause infection.
Answer:
The formula for exponential population growth is dN/ dt = rN.
Explanation:
In this equation d is the rate of change, N is the number of existing individuals, r is the intrinsic growth rate, t is time, and dN/dt is the rate of change in population size.
