Answer: Biodiversity can be decreased as a result. High temperature limits oxygen dispersion into deeper waters, contributing to anaerobic conditions. This can lead to increased bacteria levels when there is ample food supply. Many aquatic species will fail to reproduce at elevated temperatures. I hope this helps :)
Nicotine on direct application in humans causes irritation and burning sensation in the mouth and throat, increased salivation, nausea, abdominal pain, vomiting and diarrhea. Predominant immediate effects consist of increase in pulse rate and blood pressure. Nicotine also causes an increase in plasma free fatty acids, hyperglycemia, and an increase in the level of catecholamines in the blood. There is reduced coronary blood flow but an increased skeletal muscle blood flow. The increased rate of respiration causes hypothermia, a hypercoagulable state, decreases skin temperature, and increases the blood viscosity.
For amphetamine the immediate effects are quicker reaction times, feelings of energy/wakefulness, excitement, increased attentiveness and concentration, feelings of euphoria. Side effects of amphetamines can include heart palpitations, dry mouth, headache, hostility, nausea, cognitive impairment, severe anxiety, lack of appetite, teeth grinding, dizziness, increased heart rate, heart palpitations, rapid breathing rate, hypertension (high blood pressure), increased body temperature, erectile dysfunction, irregular heartbeat.
Cocaine causes a short-lived, intense high that is immediately followed by the opposite intense depression, edginess and a craving for more of the drug the side effects are Loss of appetite increased heart rate, blood pressure, body temperature, contracted blood vessels increased rate of breathing, dilated pupils, disturbed sleep patterns, nausea, hyperstimulation, bizarre, erratic, sometimes violent behavior hallucinations, hyperexcitability, irritability, tactile hallucination that creates the illusion of bugs burrowing under the skin, intense euphoria, anxiety and paranoia, depression, intense drug craving, panic and psychosis, convulsions, seizures and sudden death from high doses (even one time)
Answer:
1/8
Explanation:
The alleles that control the blood type are autosomal. The <em>A </em>and <em>B </em>alleles are codominant, and they are both dominant over the<em> i</em> allele.
<u>The possible genotypes that determine the blood types are</u>:
- Type A: ,
- Type B: ,
- Type AB:
- Type O:
<u>Color blindness is a </u><u>recessive X-linked trait</u><u>. The possible genotypes and phenotypes are</u>:
- Normal vision woman: , ,
- Color-blind woman:
- Normal vision man:
- Color-blind man:
The mom is type A and color-blind. She is and could be either or .
The dad is type B and has normal vision. He is and could be either or .
Because the daughter is type O, her genotype for blood type is <em>ii</em>. That means that both parents must have the recessive i allele. The mom is and the dad is .
To calculate the probability of having a type AB color-blind son, we need to do the Punnett Square (see attached image) and the rules of probability.
Given two independent events, the rules of probability state that the probability that both events occur is found by multiplying the probabilities of each event.
P(A and B) = P(A) x P(B)
Genes in different chromosomes assort independently, so the probability of having offspring with the genotype , is:

P= 1/4 x 1/2 = 1/8.</h2>
