Answer: True
Explanation:Carbon dioxide is transported is transfer in 3 basic ways to human cells.
About 20 % of C0 2 is transported as Carbaminohemoglobin to reach the lungs carbon dioxide binds directly to the amino acid moieties on the globin portions of the haemoglobin to form carbaminohemoglobin. This is a reversible reaction as shown below.
CO2 + Hb ↔ HbCO2.
The reversible binding of C02 to the haemoglobin is due to the the partial pressure of carbondioxde. In the lungs the partial pressure of C02 is low. Therefore C02 is unbounded from the HB and leaves in the lungs, thus the blood leaving the lungs for the body tissues has low partial pressure C02. Compare to the blood in the tissues with high partial pressure of C02 from metabolic activities of cellular respiration. The C02 therefore diffuses from the tissues to bind with HB to form Carbaminoheamologbin.
In addition C02 is transported by other means.
1. As bicarbonate 70% of the Co2 in the blood is transported and bicarbonate buffer.
CO2 + H2O CA ↔ H2CO3↔H+ + HCO3
2, As soluble carbon dioxide which dissolves directly in to the blood stream; this is about 7-10%
The alleles of offspring vary, some are dominant and some are recessive, meaning that some traits get passed down and some don't, for example,: a dominant trait might be blue eyes, a parent would have blue eyes, and pass that dominant trait to their child so that the child would also have blue eyes, recessive traits are traits that skip a generation.
For example a grandparent might have black hair, but their child won't have black hair, however, their grandchild will have black hair, therefore the black hair trait is recessive and skipped a generation

Fermentation is an anaerobic process in which energy can be released from glucose even though oxygen is not available. Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals. In these situations, your working muscles generate ATP anaerobically (i.e., without oxygen) using a process called fermentation. Fermentation is beneficial in that it can generate ATP quickly for working muscle cells when oxygen is scarce. Fermentation helps break down nutrients in food, making them easier to digest than their unfermented counterparts. For example, lactose — the natural sugar in milk — is broken down during fermentation into simpler sugars — glucose and galactose ( 20 ).
Since, the options have not been given the question is incomplete. The complete question is as follows:
The island of Guam traditionally has not had any snakes that prey on birds; however, brown tree snakes that prey upon birds were introduced. Use your knowledge of wolf-moose population dynamics to determine what happened to the population dynamics of birds and the new snakes on Guam. Which statement is probably one of the results of the snake introduction?
Because prey was abundant and few predators existed, snakes spread throughout the island.; Snake populations increased exponentially as they preyed upon birds that had no defenses against the predators.; As snake populations became very large, they reached the carrying capacity of Guam and caused bird populations to crash.; Because bird populations crashed, one of the birds' main prey items, spiders, increased their population size.
Answer: Because bird populations crashed, one of the birds' main prey items, spiders, increased their population size.
Explanation:
The wolf-moose population dynamics suggests that if the population of the moose increases the wolves will get more food and will increase in number whereas if the population of moose decrease the wolves will also decrease. This describes the predator-prey relationship.
According to the given situation, all the statements describes the predator prey relationship between birds and snake. The snake population will increase in the Island due to the availability of birds as food. But the statement, Because bird populations crashed, one of the birds' main prey items, spiders, increased their population size. is not directly related to the predator prey relationship between bird and snake. This is one of the consequences of the decline or crash of the bird population after the introduction of the snake population.
Molarity =
Moles of Caffeine = Mass of Caffeine/Molar Mass
Mass = 100 mg = 0.1 g
Molar Mass = 196 g/mole
Moles of Caffeine in one cup = 0.1/196 moles
= 5.102 * 10^-4 moles
If one cup of coffee is ingested (A typical adult contains about 40 liters of water),
Molarity of caffeine = [(5.1 * 10^-4)/ 40] M
= 0.012755 mM
The toxic molarity of caffeine in the body 10mM
How many cups will be toxic?
= Toxic Molarity/ Molarity of 1 cup
= 10/ 0.012755
= 784
In other words, you would have to drink
784 cups of coffee to reach the dose required to interfere with the DNA replication checkpoint mechanism.
