Answer:

bicarbonate-carbaminohemoglobin-dissolved in plasma

Explanation:

Transport of CO2 in the blood occurs in three main forms. Most of the CO2 is carried in the blood as bicarbonate. It accounts for transport of about 70% CO2. In RBCs, CO2 reacts with water in the presence of the enzyme carbonic anhydrase to form carbonic acid, which dissociates into H+ and HCO3-. Bicarbonate formation also occurs in blood plasma.

About 23% of CO2 is carried in the form of carbamino-compounds. Binding of CO2 to hemoglobin forms carbaminohemoglobin. The smallest percentage of CO2 (about 7%) is dissolved in blood plasma and is diffused into the alveolar air as it reaches the lungs.

Ribosomes.
Proteins are used for cellular repairing and chemical processes. Ribosomes are one of the most important organelles in the cell, mostly part of the rough endoplasmic reticulum. It manufactures enzymes such as proteins which will be utilized by many organelles in the cell. Microtubules are one, responsible for the framework and acts as a skeleton of the cell –cytoskeleton needs proteins, also cytoplasm and other organelles of the cell. For a prokaryote or a eukaryote cell to survive, they need protein.<span> Fundamentally, the cell would cease to function and possibly die</span>

An organism that reproduces sexually has a diploid number of 30. How many
Strike441 [17]

Answer:

Gamete of organism has a haploid number of chromosomes.

2n = 30

n = 15

A diploid cell containing 30 chromosomes will result in 15 chromosomes in each of the 4 daughter cells after meiosis occurs.

After first nuclear and cellular division (Meiosis I), each daughter cell will only have 15 chromosomes as homologous chromosomes are broken apart at Anaphase I of meiosis I. Chromosomal number is halved. After the second nuclear and cellular division (Meiosis II), each daughter cell will also have 15 chromosomes. This time, instead of the chromosomal number being halved, their chromosomal contents are halved. Sister chromatids are separated at Anaphase II of Meiosis II, resulting in daughter chromosomes each.

Describe the path that oxygen travels when you breathe.
lesya [120]

Answer:

The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream, carbon dioxide leaves it.
