Sperm are much smaller than eggs Why Check all likely explanations 1 Sperm need only provide DNA whereas eggs must provide cytoplasm proteins and mitochondria for the embryo 2 Sperm contain only half the DNA of an egg 3 Smaller sperm were selected because they could swim faster and reach the egg first 4 Sperm seem smaller because they are long and thin but they actually contain an equal amount of cytoplasm 5 Sperm are small to avoid being recognized by the female s immune system

The sperm of frog population A cannot fertilize the eggs of frog population B because the receptors on the egg for the arriving sperm do not recognize it. Thus these two closely related species of frogs cannot produce offspring. The isolating mechanism is: 
A prezygotic 
B. postzygotic 
C. temporal/chronological 
D. alopatric

Which statement is factual?
Asexual reproduction produces offspring that are identical to the parent.
Sexual reproduction allows for diploid gametes to combine to increase genetic variation.
Asexual reproduction leads to the formation of haploid gametes.
Sexual reproduction does not require the production of gametes.

E - Which evidence best supports the claim that jellyfish reproduce? 1. Jellyfish can make more jellyfish to continue their species. This is done with female jellyfish making eggs and then releasing the eggs when mature, at the same time male jellyfish will fertilize the eggs floating by. 2. Jellyfish babies are called "planulae". Soon the free-floating planulae will sink to the bottom of the ocean and attach on a hard surface, like a rock. They will develop tentacles and become a polyp and then soon a medusa, which is an adult jellyfish. 3. Jellyfish use their tentacles to obtain their food. If something swims by, it could get caught by the stinging cells on jellyfish. The jellyfish will then bring their food up to their mouths to ingest it. Why is your chosen evidence the best evidence for reproduction as a characteristic of life: R- Which reasoning supports the claim that jellyfish are living? 1. Jellyfish are alive because the evidence supports the claim. 2. The reason why jellyfish are alive is because they have all of the characteristics of life and to be considered living, organisms must have all characteristics. 3. The jellyfish eating is the jellyfish obtaining and using energy which is a characteristic of life and if a thing has at least one characteristic of life, it must be living.
