Hemoglobin has tetrahedral structure containing four heme groups that surround a globin group.
Heme is ringlike organic compound also known as a porphyrin to which an iron atom is attached. There are four iron atoms that bind four oxygen atoms and transport them to tissues.
The leaves are smaller, meaning the plant cannot photosynthesize as fast as before. This means that the plant cannot produce as much energy and grows slower as a result.
Answer:
Most adult amphibians can breathe both through cutaneous respiration and buccal pumping though some also retain gills as adults.
Explanation:
The blood cell will lose water and will undergo lysis.
Cell membrane is permeable to water and can get/lose water via osmosis. Osmosis is induced by the gradient of concentration of the solution. In this case, the 10M salt solution has a very high oncotic pressure that it will attract nearby water. That means the water inside the cells will be taken into the solution and cell will continue to shrink and then die.
Answer:
1. Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups.
2. The DNA double helix. The two sides are the sugar-phosphate backbones, composed of alternating phosphate groups and deoxyribose sugars. The nitrogenous bases face the center of the double helix.
3. A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
4. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
5. In genetics, the term junk DNA refers to regions of DNA that are non-coding. Some of this noncoding DNA is used to produce noncoding RNA components such as transfer RNA, regulatory RNA and ribosomal RNA
