Why do reptiles not have to return to water to lay their eggs?

Reptiles do not have to return to water to lay their eggs because they produce eggs that are already contained with liquids.

The babies must be able to hatch themselves then return back to the water, why have the eggs be in the water and then have the baby reptile be exposed to such an environment so quickly?

Hm, there is no definite answer according to my research that I've done, possibly check out your local library.

Which best describes how waste is secreted in each system
Alex777 [14]

Answer:

The digestive system excretes a solid waste, and the excretory system excretes liquid waste.

Explanation:

The digestive system is the system of the body that breaks down food substances to enhance so that they can absorb them. But it also excretes solid indigestible substances. For excreating, they use the defecation process.

Excretory system, on the other hand, is a system in the body that removes homeostatic wastes from the body by using a process which is called excretion. Excretory includes organs such as liver, sweat glands, lungs. Among this, the liver plays a critical role in the secretion of homeostatic wastes in the form of fluids.

The excretory system collects and then filters excess water which is present in the body and then excretes it as a liquid waste either from the liver, kidneys, or sweat glands on the skin through sweating.

An amoeba reproduces by splitting itself into two amoebas. This means that the original amoeba dies and its two offspring live o
Naddika [18.5K]

Answer:

If one amoeba dies then two amoeba get born:

at different stages of the generations of the amoeba it changes accordingly and the died amoeba numbers are also change in the given manner :

          stages    dies                          born

          I               1                                2

          II              2^{1}           4 = 2^{2}

          III              2^{2}          8 = 2^{3}

At  n^{th} =  2^{n}    2^{n+1}

By the geometric series formula:

 1+a^{1}+ a^{2}+ a^{3}...+ a^{n}=\frac{a^{n+1} }{a^-1} }

so,  1+2^{1}+ 2^{2}+ 2^{3}...+ 2^{n}=\frac{2^{n+1} }{2^-1} }

Thus, total amoeba died = 2^{n+1}-1

        total amoeba died+1 = 2^{n+1} (born).... hence prooved
