The answer is a, both animals have tails as embryos.
Both chicken and the cat begin with a tail, though eventually for the chick, it looses its long tail. Unlike the cat it keeps the tail it had when it was a fetus. That’s a shared characteristic embryo until they are fully developed.
There are several specific characteristics for procaryote and eucaryote:
- Procaryotes has a cell wall, in addition to the cell membrane.
- procaryotes has chromatin in the cytoplasm, they do not have a nucleus.
- Procaryotes are small cells visible only at the microscope with x100 objective.
About the eucaryotic cells:
- Eucaryotes have mitochondria,
- Eucaryotes have endoplasmic reticulum
- Eucaryotes have a nucleus with DNA chromatin and nucleoli inside it.
- Eucaryotes are visible in the microscope x40
The answer is e towards your question
Answer:
Option A) Protein carrier
Explanation:
The carrier proteins are those proteins that are involved in transfer of substances from one side to other side through plasma membrane. These are present in chloroplast, mitochondria and nucleolus.
The lipid carriers increases the absorption and solubility. These allows the transfer of non-polar molecules. The lipid carriers are used in drug delivery systems. So, this is an incorrect option.
The Porin carriers are present in the membrane of the bacteria. It allows the passive diffusion of molecules due to its large size. It only allows movement of hydrophillic substances.
The Polar molecules and ions moves across the biological membrane with the help of protein carrier. Thus, option A is correct.
Answer:
a. Men and women differ physically in some limited ways.
Explanation:
The concept of physical superiority is a relative one, so to say that one gender is physically superior to another is wrong not only socially, but also biologically. That being said, there are still some physical differences between men and women. For instance, men in average, tend to be taller and stronger than women, while women tend to have a higher pain threshold than men. Therefore, the most appropriate statement is that a. Men and women differ physically in some limited ways.
