<h2>B. Carbon dioxide emissions and global warming:We have already lost some 80 percent of the coral reefs in the Caribbean over the last three decades, and losses in the Pacific Ocean are also widespread. Reefs are like cities, with some parts growing and some parts being destroyed. When the net growth is positive, reefs can persist. Amazingly, coral reefs are threatened by such atmospheric conditions as..</h2>

Which of the following is a possible cost of using renewable resources? a. loss of animal species b. land degradation c. lower a

Eva8 [605]

Answer: d. all of the above

Renewable resources are those which can be replenished or reproduced at a faster rate. But heavily decrease in the volume of these resources sometimes cannot be compensated.

a. Loss of animal species: Hunting and poaching of animal species has limited the population of endangered species to derive valuables like horns, skins from these animals for human use.

b. Land degradation: Landmass occupied by natural forests and other natural biomes are cleared for human use like agriculture, mining, urban development. These lands are loosing their natural potential and are treated as waste lands.

c. Lower availability of fresh water: Water from water bodies like lakes, rivers, groundwater, ponds are polluted by industrial, agricultural wastes making water unfit for human use. Groundwater are pumped out to maximum amount but the same level cannot be maintained by natural sources of water such as rain, agricultural field irrigation, river or any other means therefore, limiting the level of water in grounds.

Question 6

alukav5142 [94]

The statement that provides evidence of the common ancestry of all life is near universality of the genetic code (option A).

<h3>What is the genetic code?</h3>

Genetic code is the set of rules by which the sequence of bases in DNA are translated into the amino acid sequence of proteins.

The genetic code has the following characteristics:

The genetic code is universal i.e all known living organisms use the same genetic code.
The genetic code is unambiguous i.e. each codon codes for just one amino acid (or start or stop)
The genetic code is redundant i.e. most amino acids are encoded by more than one codon.

Therefore, the statement that provides evidence of the common ancestry of all life is near universality of the genetic code.

The DNA is zipped open by the enzyme DNA helicase, to form two singles strands of DNA for that specific area of the DNA.
Then RNA nucleotides are joined to the sense strand to form a complementary strand of RNA, the RNA is small enough to leave the nucleus by the nuclear pores and go to the ribosomes. This process is called transcription

Once the zygote divides into 16 cells, it becomes known as a..............

Elan Coil [88]

Answer:

morula

Explanation:

The morula is produced by a series of cleavage divisions of the early embryo, starting with the single-celled zygote. Once the embryo has divided into 16 cells, it begins to resemble a mulberry, hence the name morula (Latin, morus: mulberry).
