a. in a punnett square, demonstrate a cross between a homozygous black/homozygous rough with homozygous white/homozygous smooth. Describe the genotype and phenotype as fractions
Answer:100% black with rough for both phenotype and genotype;4/4,1
Explanation:
so if a black coat and rough coat are dominant and a guinea pig that is a purebred(homozygous)black coat with rough coat and a homozygous white coat with smooth coat breed the dominant allele will show up for both so as a result since the black coat and rough coat are dominant the result will be 100% black with rough coat.

The following factors will affect the current oxygen and carbon dioxide levels.
Burning fossil fuels increases the output of CO2 outside of organisms that perform cellular respiration-CO2 is a green house gas and is a cause of global warming. burning fossil fuels will increase CO2 in the atmosphere which cannot be balanced by the natural sinks like forests and oceans.Deforestation reduces the number of photosynthetic organisms able to produce oxygen and consume carbon dioxide. Deforestation causes habitat loss and hence a large amount of tree cover is lost which will reduce the amount of oxygen generated and CO2 absorbed.When land is deforested for agriculture, the photosynthetic productivity of crops is not equivalent to the forests being replaced. This is so because forests have large trees and plants which have a greater photosynthesis capacity however new crops which are small and are removed annually are not able to compensate for the loss of large forest trees.learn more about oxygen and carbon dioxide levels here:

1. Erythropoietin will be higher at low altitude. Erythropoietin or EPO level will be higher because of the raised blood oxygen training but its lasting period will depend on the training content as here it is only 2 months.
About high erythropoietin:
Among the objectives of altitude training is to improve athletes' sea-level endurance performance by raising blood oxygen carrying capacity. The attainment of improved haematological variables is mostly due to the augmented erythropoietin (EPO) production in hypoxia. The duration of exposure and degree of hypoxia affect the level of the erythropoietin EPO rise and the rate of erythropoiesis acceleration. The haematological response to altitude training may also be influenced by a wide range of additional factors.
2. 100 ml of blood contain 27.8 mL of oxygen. This can be said as it has been shown that a healthy person typically possesses 20 grammes of haemoglobin in every 100 millilitres of blood.
Procedure:
=20∗1.39
=27.8mL
Amount of oxygen found in 11 grams of hemoglobin is equal to 1.39 milliliters of oxygen.
Thus, the total amount of oxygen in milliliters would be equal to product of total weight of hemoglobin and the total amount of oxygen in ml in one gram of hemoglobin.
3. Athletes training at high altitude have more oxygen molecules. They have an advantage as a result of having more red blood
Why so:
Higher elevations have thinner air, which has less oxygen molecules per volume of air. The body therefore makes more red blood cells when athletes workout at these high elevations. For up to 20 days, these additional blood cells remain in the body. Also as a result of having more red blood cells, their blood can carry more oxygen. When they compete at lower elevations, their muscles naturally get a boost from more oxygen.

During an action potential, the rapid decrease in sodium permeability and simultaneous increase in potassium permeability is responsible for __________.
During an action potential, the rapid decrease in sodium permeability and simultaneous increase in potassium permeability is responsible for Repolarization.
K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization known as repolarization.Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is is greater inside the cell than outside.
