The coccus refers to the bacteria that are spherical in their shape. They can be present in the pairs forming a row of chains of the spherical cells. The bacillus refers to the bacteria that are rod shaped. The bacillus bacteria are disease causing pathogens and are gram-positive. The aerobic bacteria uses oxygen and are generally rod-shaped. The spirillum refers to the spiral shape of the bacteria. They are rigid in their structure.
Hence, the answer is 'spirillum'.
Answer:
increase
Explanation:
The mevalonate pathway is known to generate isopentenyl pyrophosphate and dimethylallyl pyrophosphate, which are used to synthesize diverse compounds including cholesterol and steroid hormones. The levels of mevalonate in human plasma may be used as a measure of cholesterol synthesis. When the cholesterol level is low, it stimulates its endogenous production by the mevalonate pathway. Since it is well known that the vegetarian diet reduces cholesterol, this diet also increases mevalonate levels.
Answer:
The correct answers are
Question a) "50%".
Question b) "66%".
Explanation:
Achondroplasia is caused by a dominant allele, which means that a person with a "A" allele will develop this condition. In this case, all the people with Achondroplasia are heterozygotes "Aa" because the dominant genotype "AA" causes prenatal death. If a person with achondroplasia "Aa" mates with a person of average height "aa", the expected percentage of children with average height will be 50%, since there are 50% of chances of having "aa" children and 50% chances of having "Aa" children. Also, If two persons with achondroplasia have children ("Aa" x "Aa") , the expected percentage of children with achondroplasia will be 66%. The probability of having children with the "Aa" genotype is 50%, however since the "AA" genotype causes prenatal death, this genotype is not considered in the percentage.
<span>The answer would be: new combinations of the HA and/or NA proteins on the surface of the virus during viral evolution
</span><span>Antigenic shift is a mutation in the antigen that causes its shape changed. This change is dangerous because the white blood cells will not recognize them as the old virus, make the strong immune response delayed. This changes mostly caused by a random mutation.</span>
If a bacterium cannot use citrate agar will not change its color (stays green). On the other hand, if bacteria have the ability to use citrate, the medium will change its color from green to blue.
This happens because citrate agar contains pH indicator such as bromothymol blue which transforms from green to blue in alkaline conditions.
