True, the four features formed by wave deposition are beaches, spits, sandbars, and barriers beaches.
The best answer is d - Water.
Plasma is a water solution that is pale yellow in color in which all other parts of the blood are suspended.
Plasma is made up of approximately 92 % water. Proteins, enzymes, glucose, amino acids, minerals, urea, vitamins, uric acid, antibodies, salts and hormones make up the remaining 8% .
Whole blood is composed of 55% plasma. Plasma in blood acts as a solvent for gases, electrolytes, nutrients and important proteins vital to life.
<h2>Resistance to antibiotics </h2>
Explanation:
Bacteria are single-celled organisms usually found all over the inside and outside of our bodies
- Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic
- Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections,the bacteria survive and continue to multiply causing more harm
- There are two main ways that bacterial cells can acquire antibiotic resistance,one is through mutations that occur in the DNA of the cell during replication and the other way that bacteria acquire resistance is through horizontal gene transfer
- Through the process of replication bacteria develop mutations that make them resistant to antibiotics
- Bacteria with the resistant mutation have a better chance of survival against antibiotics
- Resistant bacteria continue to multiply even when exposed to antibiotics
- In horizontal gene transfer,antibiotic resistant genetic material is transferred between different bacterial cells which can happen in three different ways: transformation,transduction or conjugation
Answer: Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are known as haploid. So 23.
Answer:
d. DNA polymerase begins adding nucleotides at the 5' end of the template
Explanation:
Polymerase DNA always works in one direction, synthesizing the new 5' to 3' oriented chains and adding nucleotides to the 3' end of a new synthesis chain by forming phosphodiester bonds between the phosphate of a nucleotide and the sugar of the anterior nucleotide.
Because DNA polymerase only acts in a 5' to 3' direction, replication along a chain, the leading chain, occurs continuously. The synthesis of the opposite chain, the delayed chain, occurs discontinuously because the DNA polymerase must wait for the replication fork to open. Over the delayed chain, short segments of DNA called Okazaki fragments (named after Reiji and Tsuneko Okazaki, the scientists who discovered these fragments) are synthesized as polymerase DNA works out of the replication fork. Ligase DNA catalyzes the covalent bonds between Okazaki fragments in the delayed chain to ensure there are no gaps in the phosphodiester skeleton. Finally, the first ones are removed and these gaps are filled by the DNA polymerase.
