QUICK I NEED HELP !!!!!

Answer:

4) photosynthesis

5) volcanic eruptions

6) fossil fuels

7) ocean

8) The ocean absorbs more natural CO2, causing the acidity to decrease

9) All of the above

Answer:

When carbon dioxide CO2 is realised into the atmosphere from the burning of fossil fuel, approximately 50% remains in the atmosphere, while 25% is absorbed by land plants and trees, and 25% other is absorbed into the areas of the ocean.

Answer:

Natural selection would be the other source because organisms that have a beneficial trait will live, but organisms that do not have a beneficial trait might die. So the organsims that do survive will reproduce and pass on those traits to their offspring. Eventually all the organisms that do not have a beneficial trait will die out, leaving most of the population having that beneficial trait.

Answer: 1.)The gastric juice

             2.) The  acidic gastric

Explaining: The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria. The mucus covers the stomach wall with a protective coating.

Answer:

Nitrate

Nitrate is the form of nitrogen most used by plants for growth and development. Nitrate is the form that can most easily be lost to groundwater. Ammonium taken in by plants is used directly in proteins. This form is not lost as easily from the soil.

Answer:

The correct answer is - when a drug kills most of the bacteria, the ones left to breed are those that have a natural resistance to the drug.

Explanation:

When a drug or antibacterial medication used on the colony of a bacteria, the drug kills most of the specific bacteria from the host or culture, however, some bacteria remain to breed the next generation of bacteria as they had resistance to the particular drug.

The left bacteria breed and produce more resistant bacteria and after a few generations, a new form of drug-resistant bacteria develops. This follows the natural selection process and adapting the beneficial characteristic.

According to the scenario, it is difficult to find shelter in a grassland habitat. This is because grassland habitat generally consists of small grasses with a lack of space between them.

Habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. It may also be characterized as the area where the basic demands of an organism are fulfilled like food, water, space, mating partner, etc.

Grasslands habitats are generally open and continuous, fairly flat areas of grass. They are often located between temperate forests at high latitudes and deserts at subtropical latitudes. In these habitats, the availability of shelter is very low because of an abundance of small grasses across the area which is insufficient to build a shelter.

Therefore, it is difficult to find shelter in a grassland habitat. This is because grassland habitat generally consists of small grasses with a lack of space between them.

Answer:

Such cells, called cancer cells, divide uncontrollably and form masses of cells called tumors that can damage the surrounding tissues. ... Normal cells respond by not growing.

Answer:

Cancer cells do not respond to the signals that regulate the growth of most cells... What happens when cells do not respond to the signals that normally regulate their growth? Such cells, called cancer cells, divide uncontrollably and form masses of cells called tumors that can damage the surrounding tissues.

Answer:

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

Answer:

Lysine - Isoleucine - Arginine - Histidine - Alanine - Valine - Asparagine - Alanine - Leucine - Glycine - Val

Explanation:

Translation is the second process of gene expression in which a mRNA sequence is used as template to synthesize an amino acid sequence. This process, which occurs in the ribosome, reads the nucleotides of the mRNA sequence in three's called CODON. Each codon represents an amino acid, which is then added to the growing peptide chain.

According to this question, the following mRNA sequence is given: AAA AUU CGG CAU GCC GUU AAU GCC CUC GGG GUG A. Using the genetic code, the following amino acid sequence is produced:

Lysine - Isoleucine - Arginine - Histidine - Alanine - Valine - Asparagine - Alanine - Leucine - Glycine - Val

Answer:During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it. During uncoating, replication, and assembly, the viral DNA or RNA incorporates itself into the host cell's genetic material and induces it to replicate the viral genome.

Explanation:

Virus replication is the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before their replication can occur.

Viruses may be defined as infectious microbes consisting of an element of nucleic acid surrounded by a protein coat.

There are six steps that govern the replication of a virus. They are given below:

Therefore, it is well described above.
