While females have a second X-chromosome that masks the X-linked recessive allele, males do not, but instead have a Y-chromosome which does not represent the same alleles as the X-chromosomes, resulting in not being able to mask the X-linked recessive allele.
Answer:
False.
Explanation:
- Ozone is a triatomic gas.
- Each molecule of ozone is made up of three atoms of oxygen.
- Ozone is an extremely important gas in the atmosphere as it absorbs the maximum of incoming solar radiation and the ultraviolet rays of the sun.
- But Ozone is an extremely reactive gas and is highly dangerous if inhaled for a longer time.
- It causes damage to the lung tissue and cause respiratory ailments.
- On the other hand ozone is one of the components of Photochemical smog.
- Inhaling a significant amount of this gas can cause death.
- Hence the given statement is False.
- The correct sentence is:
Ozone protects us when it is high up in the atmosphere, it is harmful to us when we are breathing it.
Answer:
They are located in the retina (a layer at the back of the eye).
In a relative frequency distribution, the relative frequencies add up to the relative frequencies add up to 1.
- The frequency of a specific occurrence in a statistical experiment is compared to the overall frequency to determine its relative frequency. the proportion of favourable events that actually occur to all conceivable events; frequently used to assess probability. the percentage of a random variable's range that falls within a certain interval when it takes a specific value.
- Because the heights of relative frequency histograms can be translated into probabilities, they are significant. These probability histograms offer a graphical representation of a probability distribution that may be used to assess the probability that specific outcomes will materialise within a given population.
