Neither has an affect on the population.
The death rate will be larger.
Answer:
it will compare that neither has an affect on the population and it will also compare that both will be equal to one another.Hope this helps let me know if its wrong or not have a good day.
Explanation:
It will compare that neither has an affect on the population and it will also compare that both will be equal to one another.
What is population?The term "population" refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area.
Growth rates are the population changes that occur each year as a result of births, deaths, and net migration.
The total population also includes national military forces deployed overseas, merchant mariners at sea, diplomatic staff based abroad, civilian foreign nationals residing in the nation, and internally displaced people residing in the nation. Demographic tools like population predictions are frequently used.
Therefore, It will compare that neither has an affect on the population and it will also compare that both will be equal to one another.

Why have plants in the alpine biome adapted to survive on limited nutrients?
Answer:
The soil in the alpine biome is rocky and nutrient poor. Plants that live in the alpine biome must be suited to the nutrient poor soil.
Explanation:
The plants living in the alpine biome are adapted to survive on limited nutrients as the conditions in the alpine biome is harsh and not favorable. Hence, the plants have to adapt the mountain climate.
What are adaptations?An adaptation is any physical or behavioral feature of an organism that helps them to survive better in their environment. In other words, an adaptation is something that helps them in finding food, water, mates, and shelter.
The alpine climate is the typical climate for elevations above the tree line, where the trees fail to grow due to cold conditions. The climate of alpine biomes is also referred to as the mountain climate or highland climate.
Plants which are living in alpine biomes are typically low growing due to the extreme environmental conditions. There are only about 200 species of alpine biome plants which have adapted to life in cold temperatures and sparse rainfall.

which of the following statements describes a proton of an atom?
a. has a negative charge and is located in the nucleus
b. has a positive charge and is located in outer energy levels
c. has no charge and is located in the nucleus
d. has a positive charge and is located in the nucleus
Answer:
d. Has a positive charge and is located in the nucleus
Memory technique:
Think of the "p" and proton and the "p" in positive.
Think of the "neu" in neutron and "neu" in neutral.
Think about electrons and electricity. Touching something "elec"tric would hurt, or give you negative feelings.
Electrons revolve around the cell while protons and neutrons are a part of the nucleus because negative and positive things would not get along.

The correct complementary DNA sequence of 3'AGGTCAGGT 5 is - D. 5' TCCAGTCCA 3'
DNA is made of two strands of DNA strands coiled together and form a ladder-like shape. DNA molecules have four nucleotide bases that joined both strands together that are Adenine (A), Guanine (G), Thymine (T), and Cytosine(C).
Each nitrogenous base has its own complementary base in a double-helical structure.The A is complimentary T and G will have CThe complementary strand is always present in an antiparallel directionIf one strand is 3' to 5' then the complementary strand would be 5' to 3'So, in the given sequence: 3'AGGTCAGGT 5

[tex] \huge{ \underline{{ \text{Ecosystem}}}}[/tex]
No living beings can survive alone. There always exists a close relationship between living and non - living things. The environment of the earth consists of physical and biological factors. The physical and biological factors together constitute an ecosystem. The ecosystem may be natural or artificial , temporary or permanent. Thus, an ecosystem is an ecological unit which consists of both biotic ( living ) and abiotic ( non - living ) factors of the environment. The organisms and the environment are inseparably interrelated and interactive in their nature. A.G. Tansley ( 1935 ) , a British ecologist used the term ecosystem first.
