Vernon is studying the population of deer in a tract of forest. He gathers the following data. Birth rate:-50 deer/year
Death rate:- 70 deer/year
Which additional observation would support the conclusion that the deer population is NOT changing size from year to year, meaning that trat net
population change is 0?
A About 20 deer per year immigrate to the tract of forest.
0
O
B. About 20 deer per year emigrate from the tract of forest
С
The average life span of a member of the deer population is 20 years.
O
D
If a deer survives its first year of life, its average life span is 20 years.

dna is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).

wha is what i will use to get my free points

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

the answer is d p: cell, q: organ, r: organ system, s: tissue
