Write a set of directions for a red blood cell to deliver oxygen to the brain. Lungs heart-brain aorta arteries veins
Answer: How does oxygen get into the bloodstream? Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.OK Our typical red cell passes from the capillary into the venules, and then into veins. It flows back to the right side of the heart, completing the second loop of its circuit [music out]. As we saw, it then travels back to the lungs.The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

Which statement about oogenesis is correct?
A. Diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body.
B. Two diploid secondary oocytes undergo meiosis II to form four haploid ootid cells.
C. Haploid secondary oocytes undergo meiosis I to form a haploid ootid cell and a polar body.
D. Haploid secondary oocytes undergo meiosis II to form a diploid ootid cell.
The statement which is true about oogenesis is that the diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body. Thus, the correct option for this question is A.
What is Meiosis?Meiosis may be defined as a type of cell division in which each parental cell is divided into four daughter cells. These daughter cells are genetically unique to the parental cells and are haploid in nature. Germ cells (gamete cells) are typically divided through this mode of cell division.
Oogenesis may be characterized as the process of female gamete formation including the formation of an oocyte from an oogonium followed by meiotic division. During the process of oogenesis, a haploid ootid cell and a polar body are formed with the help of meiotic division.
Therefore, the statement which is true about oogenesis is that the diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body. Thus, the correct option for this question is A.

What is the effect of an increased concentration of calcium ion in the sarcoplasm?
Answer:
When calcium concentration increases during depolarization, it shifts the conformation of troponin and tropomyosin, and actin is able to associate with myosin. As calcium is taken up again by the sarcoplasmic reticulum the muscle cell relaxes.
The effect that can be associated with increase in concentration of calcium ion in the sarcoplasm is :
Changing of shape and position of tropomyosin.
Can also cause muscles stiffness.
When the Ca2+ concentration become high in the sarcoplasm, there would be change in the position of tropomyosin as result of the binding effect of Ca2+ binds on troponin.Then the tropomyosin will be moved away from myosin binding sites on actin, then a cross bridge will be formedHowever, the effect if this on muscles is muscles stiffness.

Explanation:
North Carolina’s biotech industry is quickly expanding.
Within the state, there are more than 600 life science companies employing 61,000 people at an average salary exceeding $81,000 a year – which is nearly twice the state’s overall private sector wage, according to the North Carolina Biotechnology Center.
In total, life science companies and institutions in North Carolina generate $73 billion in economic activity, which is an increase of 23 percent in two years, and account for 228,259 direct and indirect jobs, says North Carolina Biotechnology Center.
Furthermore, while employment in the nation’s life science industry rose by 7.4 percent from 2001 to 2012, North Carolina’s grew at a surprising 31 percent, even with setbacks from the Great Recession of 2008.
Following closely behind California, North Carolina outpaced life science industry growth in other states, including Texas, New York, Massachusetts and Florida, between 2009-2012, according to the U.S. Bureau of Labor Statistics. In the chart below, North Carolina's life science industry grew 5.2% from 2009 to 2012. While California's life sciences industry increased even more at 5.5% during the same time period, other states such as Pennsylvania and New Jersey actually saw their life sciences sectors shrink by 7% and 7.3%, respectively.
Isometric training is ideal for immobilized rehab situations, they facilitate recovery and reduce muscle atrophy and strength loss
Answer:
An isometric training is a static contraction of a muscle.
Explanation:
An isometric training is a type of exercise which involves the static contraction of a muscle where no visible movement in the angle of the joint occur. Isometric exercises helps in maintaining and recovery of strength of our body. They can also build strength, but not very effectively like other exercises. During isometric training, the muscles doesn't change its length and the affected joint doesn't move from its place.
A baker activates yeast cells with hot water, and adds sugar as their source of food. As the yeast begin their metabolic processes, the bowl it is in is covered with plastic so that no oxygen can get to them. At this point, the yeast will __ *

a. produce far more ATP than is necessary in response to the lack of oxygen
b. continue to go through aerobic respiration if enough sugar is present
c. die since all living organisms need oxygen to survive.
d. perform anaerobic respiration in the absence of oxygen
Answer:
The correct answer would be - option D. perform anaerobic respiration in the absence of oxygen.
Explanation:
Yeast is a facultative anaerobic single-cell organism that can live without oxygen. If yeast cells did not get the oxygen they use anaerobic respiration to get the energy.
If the baker activates these cells and stops them to get oxygen the yeast cells have to switch to anaerobic respiration to survive and produces ethanol and releases carbon dioxide.

Answer:The option are not given, here are the options gotten from another website.
A. Aerobic respiration
B. Electron Transport Chain
C. Anaerobic respiration
D. Krebs cycle
The correct option is C.
Explanation:
This is because anaerobic respiration is a type of respiration that produced ATP. pyruvate are metabolize in the absence of oxygen by a process called fermentation and fermentation us anaerobic respiration. And fermentation is the chemical process where glucose or substrates are broken down in the absence of oxygen by the activities of enzymes. When pyruvate are metabolize in the absence of oxygen , it will produce lactate.
In the presence of oxygen, all cells synthesize ATP via the process of glycolysis. Many cells also can metabolize pyruvate if oxygen is not present, via the process of fermentation.
In biology, an incomplete oxidation process is called fermentation, which does not require oxygen to take place, and which produces an organic substance as a result.
Fermentation consists of a process of glycolysis (breakdown of the glucose molecule) that produces pyruvate (pyruvic acid).
As it lacks oxygen as a receptor for the excess electrons of the NADH produced (nicotin adenine dinucleotide), it uses an organic substance that must be reduced to reoxidize the NADH to NAD +, finally obtaining a derivative of the initial substrate that is oxidized.
In this process, then, neither the mitochondria nor the structures linked to the cellular respiration process are involved.Only 2 molecules of ATP are produced per molecule of glucose consumed.It is carried out by the muscle cells that ferment glucose when the oxygen input is not enough to continue breathing.Therefore, we can conclude that many cells also can metabolize pyruvate if oxygen is not present, via the process of fermentation.
