Answer:

By releasing CO2 it would warm the planet and help plants grow. But realising too much would be one cause of global warming. Also, more CO2 in the atmosphere would cause the ocean water to become more acidic, putting marine life in danger.

Explanation:

Trees are big parts in life. Without them, many things can happen. For example, CO2 is not what humans breathe. We breathe in Oxygen. Deforestation can lead to bad air and soon we’d all be breathing in cO2.

Answer
A S'AGGTCAGGT 3
B
S'ACCUGAGGU 3
C 5'TGGACTGGA 3
D 5' TCCAGTCCA 3

Answers

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

     Complementary sequence:       5' TCCAGTCCA 3

Thus, the correct option is: option D. 5' TCCAGTCCA 3

Explanation:

[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.

Question:

☞ What is ecosystem?

Answer:

Ecosystem is a community of living organisms interacting with each other and their non-living environment. It means that it is an area where organisms interact with one another as well as with non-living parts of the environment. An ecosystem can be huge, such as a large forest or lake, or it can be small, such as a puddle of water or a rotting log. Hence, All things that interact in an environment make up an ecosystem.

An ecosystem has two parts:

Biotope - it includes all of the non living things in an ecosystem.

Biocoenosis - It includes all the living things in an ecosystem.

What is DNA?

Deoxyribose + phosphate group + thymine could be a nucleotide of DNA and defined as deoxyribonuclic acid and it is a polymer made up of two polynucleotide chains that arranged in foiled structure to form a double helix carrying genetic information for the various processes such as growth development  functioning and reproduction.

There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.

Friedrich miescher discovered DNA in the year of 1860.The shape of DNA is double helical structure

The main function of DNA is to carry information from one generation to another generation this is the reason due to which DNA is also known information molecule.

In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA. The shape of DNA is double helical structure.

Siblings share only about 50% of same DNA due to the reason of recombination. The life span of DNA is 521 years.

Why have plants in the alpine biome adapted to survive on limited nutrients?

Answers

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.
