In eukaryotes, extranuclear inheritance occurs when genetic information is transmitted by mechanisms other than through nuclear DNA. Mitochondrial DNA. (mtDNA) is an example of one mechanism by which extranuclear inheritance can occur. The statement that correctly describes mtDNA are that mitochondrial chromosomes contain genes that are involved in oxidative phosphorylation and mtDNA organization is more similar to that of prokaryotes than eukaryotes.
Mitochondrial DNA (mtDNA) is a type of DNA that is located in the mitochondria of eukaryotic cells, this DNA is not present in the nucleus of the cell. As a result, mitochondria are inherited in a unique manner, which is distinct from Mendelian genetics. Mitochondrial inheritance occurs when the genetic information is passed from mother to offspring. Mitochondrial chromosomes contain genes that are involved in oxidative phosphorylation.
Oxidative phosphorylation is the final phase of cellular respiration, it involves the electron transport chain, in which oxygen is the ultimate electron acceptor, and it results in the production of ATP (adenosine triphosphate), which is the primary energy source for cells. mtDNA organization is more similar to that of prokaryotes than eukaryotes, the genetic organization of mtDNA is relatively simple. In contrast to nuclear DNA, which can contain tens of thousands of genes, mitochondrial DNA typically contains only a few dozen genes. Additionally, mitochondrial chromosomes are circular in shape, which is more similar to the genetic organization of prokaryotes than eukaryotes.

in seed plant reproduction, when does the diploid zygote form?
In seed plant reproduction, the diploid zygote forms when the male and female gametes fuse together.
The male gamete is found in the pollen grain and is produced in the anther of the flower, while the female gamete is found in the ovule and is produced in the ovary of the flower. During pollination, the pollen grain lands on the stigma of the flower and begins to grow a pollen tube that penetrates the style of the flower and reaches the ovary. The nucleus of the male gamete then moves down the pollen tube and fuses with the nucleus of the female gamete inside the ovule. This process is known as fertilization and forms a diploid zygote. The zygote then undergoes mitosis to form an embryo, which is the first stage of the new plant. The embryo remains dormant inside the seed until conditions are favorable for it to germinate and grow into a mature plant. In conclusion, the diploid zygote forms when the male and female gametes fuse during fertilization in seed plant reproduction.

Answer:
Chlorophyll or chlorophylls
the _________ is a large, saw-toothed, flat, fan-shaped muscle positioned between the ribs and the scapula.
Answer: serratus anterior
Explanation:
why was the of rate of co2 per minute so low for 1% galactose when compared to 1% glucose?
Because yeast needs nearly an hour to reach the stage of utilising galactose, whereas glucose occurs immediately, the rate of CO2 per minute for 1% galactose was much lower than that for 1% glucose.
Although yeast and galactose can substitute glucose, it is usually the substrate for anaerobic respiration. Glucose's isomer is galactose. Only their atoms' arrangement is different between them. Stereoisomers of each other exist between glucose and galactose. The hydroxyl group's (OH) orientation at carbon 4 is the primary structural variation between galactose and glucose.

What force allows a plant to become more rigid and stand upright?answer choiceso turgor pressureo geotropismo photosynthesiso phototropism
Turgor pressure is the force that allows a plant to become more rigid and stand upright. Turgor pressure is the pressure exerted by water inside the plant's cells against the cell walls. The water enters the plant's cells through a process called osmosis, where water moves from an area of high concentration to an area of low concentration.
When the plant's cells are filled with water, they become swollen and exert pressure against the cell walls, which gives the plant its rigid structure. This turgor pressure is especially important for plants that grow upright, such as trees and flowers, as it helps them maintain their shape and resist external forces such as wind and rain.
Turgor pressure is also essential for plant growth and development. Without adequate turgor pressure, plants may wilt, and their growth may be stunted. Therefore, maintaining proper water balance and turgor pressure is critical for the health and survival of plants.

The amino acid in hemoglobin that is found to be most sensitive to pH changes and hence affects oxygen-binding process around pH 7 is histidine.
What is hemoglobin? Hemoglobin is a protein that helps in the transportation of oxygen to the tissues in your body. Hemoglobin is found inside red blood cells, which gives them their distinctive red color. Hemoglobin is a protein that can be found in the blood that is responsible for carrying oxygen to the cells of the body.
Hemoglobin is made up of four polypeptide chains, each of which contains an iron molecule. Hemoglobin aids in the transport of oxygen to the lungs and carbon dioxide to the rest of the body. The most important amino acid residues in hemoglobin are histidine and tryptophan.
Histidine plays a crucial role in the functioning of hemoglobin. Hemoglobin releases oxygen in response to low pH, which occurs in response to the buildup of carbon dioxide. His146 (also known as the "Bohr Effect") is a crucial amino acid residue in hemoglobin that is involved in oxygen binding and release.
When there is an increase in H+ concentration (lowering of pH) in the blood, His146 and other histidine residues in hemoglobin becomes more positively charged. This causes the oxygen-hemoglobin affinity to decrease, which causes more oxygen to be released to the cells.
