Answer: Amniotic eggs
Explanation:
Amniotes are the characteristic feature of tetrapod vertebrates comprising the birds, mammals and reptiles. The amniotes lay their eggs on the land and retain the fertilized egg inside the mother.
They are differentiated from the from the organism which lay eggs in water. Anamniotes are the organism which are specialized to live in water and they cannot survive on land.
Hence, the correct answer is Option 4
The organism that is most affected by increasing the acidity of water is the clam.
One of the factors that affect aquatic organism is the pH of the water. The pH is a measure of the acidity or alkalinity of the water body. The pH of water bodies could be increased by phenomena such as acid rain, industrial waste disposal etc.
The organism that is most affected by increasing the acidity of water is the clam because acidity of water affects the availability of CaCO3 in water which is necessary for the formation of a carbonaceous shell.

Answer:
No, it is not.
Explanation:
Looking at this chart, this looks to me to be a case of an x-linked recessive disease. (If you want to know how to tell, or got some context that this is not the case, let me know)
Remember that females have two x chromosomes and males have one x and one y chromosome. As this disease is recessive, this means that for a female to exhibit the disease, she must have both x chromosomes have the disease. If she only has one x chromosome with the disease, she's considered a carrier.
On the other hand, males are completely binary, as they only have one x chromosome - either their x chromosome has the disease, and they exhibit it, or their x chromosome does not, and they do not have the disease, nor do they carry it. Thus, males can also not be carriers.
A square on the chart is representative of a male, while a circle is a female. IV-2 is a square, thus he is a male. This means that he cannot be a carrier, so your answer is no.
If any of this doesn't make sense, feel free to let me know! Hope this helps.
Answer:
E. are a dormant form of a bacterium AND are formed by members of medically relevant groups of bacteria.
Explanation:
Endospore is a structure formed by some bacteria when exposed to unfavorable conditions like lack of nutrition. It is a dormant non reproductive structure. When the bacteria is exposed to favorable condition, it regains its natural vegetative state. Endospores contain a large amount of dipicolinic acid which helps in the bacteria's dormancy.
Endospores are medically important because they are resistant to all the methods of destroying bacteria like UV radiation, desiccation, disinfectants and freezing. Two endospore forming genus, Bacillus and Clostridium are reason for many diseases. <em> Bacillus anthracis </em>causes anthrax which is very fatal to humans. <em>Clostridium botulimum</em> causes botulism and <em>Clostridium tetani </em>causes tetanus.
