Answer:
true

remember- Haploid it sounds like half, so when you think of half, always think of sex chromosomes. 23 chrom.
diploid- well its the other one so yeah 46 chrom.
Answer:
The extraction of resources affects the environment by changing it
Explanation:
We know the environmnet changes when we see more polluted air. This happens because of the extraction of trees in our environmnet. People cut down trees to make things, they dont undertsand the importance of trees. We need them to survive. Trees provide oxegen for us to breate and live. The more trees we cut down, the more polluted air we breath in.
Answer:
Diffusion in the Lungs trades out Carbon Dioxide (CO2) for Oxygen (O2) In the Circulatory system it trades Oxygen (O2) for Carbon Dioxide (CO2)
Explanation:
As you breathe the Lungs take in air, as they do that the air travels to the bronchi, from there it goes through a process where the veins which have carried de-oxygenated blood to be diffused and reloaded with Oxygen and trade off their CO2. Then the blood flows through arteries and delivers the needed O2 to cells throughout the body and the cycle repeats.
The right answer is the promoter.
• The promoter is a nucleotide sequence that allows the transcription of the gene into mRNA. It is recognized by the RNA polymerase that initiates transcription. During the synthesis of the RNA, the promoter indicates which gene must be expressed and therefore which proteins the cell must produce. In an operon it is common to all genes.
• The operator is a segment of DNA and / or messenger RNA to which a chemical signal (a regulatory molecule) binds. It can be either a repressor signal or a transcription activating signal (DNA operator) or translation (RNA operator) of the genes of the operon. The RNA polymerase does not recognize this structure.
