Answer:
it will reduce the ability of white blood cells to guide against disease
Answer: Well they simply would have a hard time breathing
Explanation:
Damaging your lungs can prevent your endurance. You would always have shortened breath and you couldn't do much if your lungs are becoming damaged. It will also slow the amount of oxygen you intake which can lead to other problems in your body.
We know that each parent must give one trait to a child. If that is the case, then the women has a probability of giving either an A or a B gene (since she is heterozygous AB). In order to have an A child, the child must have a genotype of either Ai (heterozygous A), or a AA (homozygous A). Since we know that the mother gave an A gene, we are now only looking for either an 'i' (recessive: stands for blood type O), or an A. Since the choices shows the phenotypes of the possible father, then their genotype could be homozygous or heterozygous (since the phenotype does not show whether an organism has a recessive gene if it's heterozygous). If that is the case, then all of them could be the father of the child.
Proof:
for letter A: mother Ai or AA x father AA or Ai = possible offspring are: AA, Ai, or ii
B) mother Ai or AA x father Bi = AB, Ai, Bi, ii
C) mother Ai or AA x father ii = Ai, ii
D) mother Ai or AA x father AB = AA, AB, Ai, B
All of them have the probability of having an A child.
Answer:
Answer 1: <em>Producers</em> represent the most biomass in an ecosystem.
Answer 2: <em>Human and animal respiration, decomposition and volcanic eruptions</em> are natural sources of carbon emissions.
Explanation:
Answer 1: <em>Producers</em> represent the most biomass in an ecosystem.
Producers refer to plants, trees, shrubs, etc., that make up the first trophic level of an ecosystem. Producers are vital to ecosystems as they produce food for themselves as well as primary consumers. Producers represent the most biomass in an ecosystem as they are the first trophic level in an ecosystem. As we go up trophic levels in an ecosystem, only 10% of energy as biomass is passed on to the next trophic level. Thus, producers represent the most biomass in an ecosystem.
Answer 2: <em>Human and animal respiration, decomposition and volcanic eruptions</em><em> </em>are natural sources of carbon emissions.
Respiration is a natural source of carbon emissions as, when humans and animals exhale, they release carbon dioxide and water vapor in the atmosphere. Similarly, when plants and animals die and decompose (decay), carbon dioxide is released in the atmosphere as part of the decomposition process. Thirdly, volcanic eruptions are also a significant form of carbon emissions as annually, 200 million tonnes of carbon dioxide is released from the earth's interior when volcanoes erupt. In this way, human and animal respiration, decomposition and volcanic eruptions are natural sources of carbon emissions.
