Triggerfish and hawks fish. They have depressed body shape and their tail is diphycercal. Their tail shape gives them manoeuvrability and their body shape allows them to fit into small places on the reefs which makes them good for adaptations.
Shark fish; they have fusiform body shape and heterocercal tail shape and their good adaptation help them to be top predators and need speed to hunt down their animal.
Stingray; they have depressed body shape and diphycercal tail shape. Their good adaptation helps them to timid fish who feed and hide along the bottom.
Answer:
9 normal : 3 striped : 3 spotted: 1 striped and spotted.
Explanation:
The F1 progeny contains no spots or stripes and are considered as normal, it means normal tail and normal head are dominant on their alternative traits. So, it means that the F1 progeny are heterozygous in nature for both of the traits.
The cross between 2 F1 progeny is dihybrid cross of lizards (heterozygous) which will produce offspring in 9:3:3:1 ratio, where 9 are normal, 3 striped which are dominant in the one character, 3 spotted which are dominant in other, and 1 will be stripped and spotted which is recessive in nature.
Answer: b. It only arrest growth of vegetative cells
Explanation: An antimicrobial agent is a substance that kills o control the growth of microorganisms, for humans this is very important in medicine or agriculture among others.
This agent should act quickly and being stable that help it to make it cheaper, also should not harm humans or other host of the microbial organisms.
The agent is not useful if only kills vegetative cells because it is not preventing the reproduction of the organism specially in fungi which use sexual reproduction as a backup for asexual cell division, so they will keep spreading across the host.
