stepladder [879]

Answer:

We live in an era of unprecedented road and highway expansion — an era in which many of the world’s last tropical wildernesses, from the Amazon to Borneo to the Congo Basin, have been penetrated by roads. This surge in road building is being driven not only by national plans for infrastructure expansion, but by industrial timber, oil, gas, and mineral projects in the tropics.

Few areas are unaffected. Brazil is currently building 7,500 kilometers of new paved highways that crisscross the Amazon basin. Three major new highways are cutting across the towering Andes mountains, providing a direct link for timber and agricultural exports from the Amazon to resource-hungry Pacific Rim nations, such as China. And in the Congo basin, a recent satellite study found a burgeoning network of more than 50,000 kilometers of new logging roads. These are but a small sample of the vast number of new tropical roads, which inevitably open up previously intact tropical forests to a host of extractive and economic activities.

Explain how ionic balance is maintained in the human body​
krek1111 [17]

Answer: Our kidneys filter out excess ions from our blood so that they can be excreted through urine. If the concentration of ions is too high, the kidneys make sure to filter as much of them as they can out of the body. If there are not enough ions, the kidneys will filter them back into the system.

Hope it helps

Point where crossing over takes place between chromatids of the homologous chromosomes during prophase 1
Free_Kalibri [48]

Answer:

Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.

Explanation:

When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.

Discribe the processes of transcriotion and translation
gogolik [260]

Answer:

Please find the explanation of transcription and translation below using the key words.

Explanation:

Transcription is the process whereby a gene in a DNA template is used to synthesize a messenger RNA (mRNA) molecule in the nucleus of the cell. This process of transcription occurs with the aid of an enzyme called RNA POLYMERASE, which adds the nucleotides complementary to the one it reads in the gene to the growing mRNA strand.

Translation, on the other hand, is the second process of gene expression involving the synthesis of proteins from the mRNA sequence. This process occurs in the RIBOSOME where a group of three nucleotides in the mRNA called CODON is read by another group of complementary nucleotide in the transfer RNA (tRNA) called ANTICODON. The tRNA then carries amino acids corresponding to what is read in the codon to the growing polypeptide chain.
