Answer:
The greenhouse effect is a natural process that warms the Earth's surface.
Explanation:Greenhouse gases cause the earth to warm up
Answer:
The policy for controlling environmental mercury pollution should address ways to prevent and control this pollution. Policy:
- Ban the incineration of waste
- Require that coal-burning companies remove mercury from the coal
- Allocate funds towards research and development for renewable energy resources in the hopes of switching away from coal.
- Require that products containing mercury be labeled as such.
- Set up programs that will recycle batteries and mercury-filled products.
- Set up education programs that will help inform people about mercury pollution.
This policy works by addressing the ways to prevent and control mercury pollution.
Three problems that could result from implementing this policy:
- Backlash from coal-burning companies.
- It could take a while before we completely shift away from using coal.
- Some of the programs that can be set up in this policy can be too expensive to set up and maintain.
Amoeba are the consumers that surround, engulf, and ingest their food.
<h3><u>Explanation</u>:</h3>
Amoeba is a unicellular organism that belongs to the kingdom Protista. This organism are having eukaryotic cells without any cell walls. These organisms have each and every cellular organelle that are needed to perform metabolism.
Amoeba are consumer in mode of nutrition. Whenever they senses some food, they push a part of their cytoplasm packed in cell membrane towards the food to cover it. This process is called pseupodia.
This pseupodia engulfs the food and performs phagocytosis or pinocytosis. This food is covered in a cell membrane inside the cytoplasm which is called the food vacoule or endosome. This then fuses with a lysosome to digest and then the excretory product is let off by the secondary vacoule.
Answer:
The plasma membrane is made up by a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment. Only relatively small, non- polar materials can easily move through the lipid bilayer of the plasma membrane.
Explanation:
Answer:
gDNA = "genomic DNA" and cDNA = "complementary DNA." cDNA is classically associated with being reverse transcribed either from all extracted RNA from a tissue or cell (total RNA) including (in eukaryotes) pre-mRNA, ribosomal RNA, tRNA, snoRNA, miRNA and mRNA, etc.) while cDNA obtained only from reverse transcription of the mRNA (expressed eukaryotic cytosolic mRNA) fraction (e.g., by poly[dT]n and random priming) is complementary DNA (cDNA) made from what is called the "transcriptome." Eukaryotes have introns and exons in the gDNA, while prokaryotes do not. So eukaryotic cDNA reverse transcribed from mRNA lacks introns. Prokaryotic-derived cDNA is always complementary to prokaryotic RNA and gDNA (so is always necessary to have a good DNase treatment prior to gene expression analysis by e.g., qPCR for prokaryotic transcriptome work)...
