The answer is dams they protect against flooding
Answer:
Low calcium levels in the <em><u>blood</u></em>
Explanation:
In primary hyperparathyroidism, one or more of the parathyroid glands is overactive. As a result, the gland makes too much parathyroid hormone (PTH). Too much PTH causes calcium levels in your blood to rise too high, which can lead to health problems such as bone thinning and kidney stones. <em> </em><em>this</em><em> </em><em>w</em><em>i</em><em>l</em><em>l</em><em> </em><em>h</em><em>a</em><em>p</em><em>p</em><em>e</em><em>n</em><em> </em><em>i</em><em>f</em><em> </em><em>p</em><em>a</em><em>r</em><em>a</em><em>t</em><em>h</em><em>y</em><em>r</em><em>o</em><em>i</em><em>d</em><em> </em><em>h</em><em>o</em><em>r</em><em>m</em><em>o</em><em>n</em><em>e</em><em>s</em><em> </em><em>g</em><em>o</em><em>t</em><em> </em><em>h</em><em>i</em><em>g</em><em>h</em><em> </em><em>i</em><em>n</em><em> </em><em>h</em><em>u</em><em>m</em><em>a</em><em>n</em><em> </em><em>b</em><em>o</em><em>d</em><em>y</em><em>.</em><em>.</em>
Answer:
9 per 1,000/yr.
Explanation:
The population growth rate is 9 per 1,000/yr.
The rate of growth of population is determined by the following formula:
<em>Growth rate = B - D + I - E</em>
<em>Where B = birth rate, D = death rate, I = immigration, and E = emigration</em>
In this case, B = 26, D = 15, I = 7, and E = 9. Substitute these values into the equation of growth rate.
Growth rate = (26 - 15) + (7 - 9)
= 11 - 2 = 9
<u>Hence, the growth rate of the deer's population is 9 per 1,000/yr.</u>
Answer: Scientists think that early amphibians had lungs becuase they needed efficient oxygen uptake to support their metabolism. Higher rates of metabolism are needed on land, becuase of this scientist think that early amphibians breathed air with lungs.
Explanation:
it will have to be B. Populations will decline since individuals will be less likely to successfully reproduce. because they will not be able to breed with other birds on the breeding grounds.
