Why do identical twins have the same physical characteristics, whereas regular siblings are not identical?

Biology

It’s because unlike twins the regular siblings aren’t born on the same date or a couple minutes apart, but rather a couple years old or younger.

Which best describes the offspring of protists?
Hunter-Best [27]

Options found elsewhere:

-always genetically identical to one parent

-always genetically identical to both parents

-never genetically identical to one parent

-sometimes genetically different than both parents

Answer:

-sometimes genetically different than both parents

Explanation:

Protists are eukaryotes that cannot be classed as animals, plants, or fungi. They are quite diverse. Examples include amoeba, plasmodium, and slime mould.

Because they are so diverse, protists also have very different modes of reproduction. Some protists undergo asexual reproduction, where they simply make a copy of themselves without a mate. Others undergo sexual reproduction.

Therefore, the only option that can be correct is "-sometimes genetically different than both parents" .

If they were always genetically identical to one parent or both parents, that would mean that sexual reproduction could not be possible. If they were never genetically identical to one parent, that would mean that asexual reproduction could not be taking place.

Hello?? Can anyone help me??! PLEASE
kolezko [41]

Answer:

The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.

I don't think I put enough detail into that explanation but I hope this helps your problem.

a cell is placed in a solution of 3% starch and 3% glucose. After several hours, glucose is detected outside of the cell, but st
Alex17521 [72]

Answer and Explanation:

The cell was placed in a hypertonic solution. Glucose is a monosaccharide while starch is a polysaccharide. The concentration on the outside is higher compared to that on the inside. The cells have cell membrane that is semi-permeable.

Movement of molecules is dependent on the concentation gradient. However, the size of molecules determine the diffusion rate. Small and light molecules diffuse faster than large and heavy molecules thus glucose diffused faster than starch.

The cell membrane being permeable suggested that it allows molecules of small sizes to pass but not large ones.
