Please help to explain why pine trees have needles instead of leaves and cacti have spines instead of leaves.If possible please relate these adaptations to their habitats.

And if you want to be FABULOUS....then evaluate the pro’s and opinion, justifying your ideas of the following: Pine trees are forested as a constructional timber.

Thank you for any ideas contributed, it is very much appreciated! :3 ♥ 12 Points+Brainliest for the best answer

Answers

developed a way to protect their foliage. Instead of flat leaves, pine trees have needles. These needles are the key to the Winter survival of the pine tree. Needles cut evaporation sotrees can save water!
Cacti have sines instead of leaves because they help protect them from getting eaten and they don't need leaves because they store water inside themselves.
They both have adapteations to help them servive in very harsh conditions. Cacti use their adaptations to survive in scourching heat and pine trees can servive in freezing cold.

Which statement is one component of the cell theory?

Answers

The options attached to the question above are given below:

A. All living and nonliving things consist of one or more cells.

B. Cells and living organisms are spontaneously created.

C. Cells are the most complex unit of structure and function in living things.

D. A cell is the basic unit of structure and function of all organisms

ANSWER

The correct option is D.

The cell theory is one of the major theories in biology and it states the facts about living cells. The theory states that, the cell is the most basic unit of all organisms and all living organisms are made up of one or more cells. The organisms that are made up of only one cell are described as unicellular while those that possess many cells are described as multi cellular. The theory also states that all cells come from pre-existing cells.

the correct answer is d

An organism may be multicellular or unicellular true or false ?

Answers

True, an organism may be either multi- or uni-cellular

The triplet code can produce 64 possible codon combinations. What is an advantage of this? A. Every single codon specifies more than one amino acid. / B. Every single amino acid has more than one codon. / C. The first two bases of the codon specify the amino acid.

Answers

The answer is B. Every single amino acid has more than one codon.

There are 20 different amino acids, but there are more than 20 combinations of three nucleotide bases on DNA. There are 64 different combinations of three nucleotide bases on DNA, which is about 3 times more than the number of amino acids. Therefore, every single amino acid has more than one codon is the right answer. But, it should be taken into consideration, that 2 out of 20 different amino acids have only one codon - methionine and tryptophan.

The characteristics of all organisms and viruses are determined by the instructions carried in _______. A. hydrogen bonds B. nucleic acids C. sugar bases D. phosphoric acids

Answers

the correct answer is B. the information that decides the characteristics of all organisms are contained in their nucleic acids. Nucleics acids are DNA and RNA. DNA have genes that code for proteins which are responsible for the structural and functional characteristics of organisms. DNA is transcribed into RNA and RNA is translated to proteins. Therefore information that is in these nucleic acids determines all the characteristics of organisms

The characteristics of all organisms and viruses are determined by the instructions carried in nucleic acid.

Further Explanation:

Nucleic acid is an information molecule that plays an important role in the storage and transmission of hereditary information. They are polynucleotide that means it is composed of a long chain of molecules. It is composed of a series of nucleotides that are identical to each other. It is the primary component of the DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA is the double-stranded genetic material that is present in each living cell. RNA is a single-stranded genetic material that helps in many cellular activities such as protein synthesis.

DNA acts as a master blueprint for life. It is present inside all living organism both eukaryotes and prokaryotes. It is present in bacteria and most viruses. RNA is the genetic material that is present in the certain virus. The genetic material helps in determining the class or species of the organism.
