The cell wall is semi-permeable.The membrane is permeable and controls the movement of the substance into and outside the cell. That is, it can allow water and other substance to pass through selectively. Functions include protection from the external environment.

Answer:
According to the statement of the question, this problem is solved by analyzing the sex chromosomes for the determination of sex, that is, as it does not present the problem (genotype and phenotype) of the parents, the indication that refers to the determination of sex, in women and his sex chromosomes are "XX" and the man who determines sex is "XY".
The result of sex in the offspring corresponding to the man, if the chromosome in the sperm fertilizes the ovule is "X", then the sex or phenotype of the individual will be "XX" (female) and if the fertilizing sperm is "Y" then the sex will be "XY" of male, the probability of being born female or male will be 50% and 50% and the ratio is 1: 1
Answer:
Eukaryotic cells contain a membrane-bound nucleus and numerous membrane-enclosed organelles (e.g., mitochondria, lysosomes, Golgi apparatus) not found in prokaryotes. Animals, plants, fungi, and protists are all eukaryotes.
Explanation:
The nucleus works together with a group of organelles that make up what is called the endomembrane system. They are the factories which build the cell. Ribosomes are small structures found in the cytoplasm which make proteins.
ANSWER ( Convergent plate boundaries )
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
