describe and explain the adaptations of sperm and ovum that enables fertilisation and early development of the embryo to occur​

Biology

The adaptations of the sperm and egg that allow fertilization to take place, and copulation occurs for the sperm to be deposited. These sperm penetrate the cervix and travel to the fallopian tube. There, they must find an oocyte, which is released in the process of ovulation.

<h3>What is fertilization and embryo development?</h3>

In the first weeks after fertilization, the zygote makes many changes and develops rapidly. The first eight weeks of development is known as the organogenic period and is the embryonic stage of development. This period is a crucial phase of development for the embryo's organs.

With this information, we can conclude that The first three days of embryonic development occur in the fallopian tube as the embryo moves from the ovary to the uterus. Cell division continues and forms a hollow ball of cells (the blastocyst). Six days after fertilization, the embryo begins implantation into the lining of the uterus.

Why are some molecules polar and others non polar
Gennadij [26K]

Answer:

Polarity and Non-polarity of molecules depend upon the electronegativity. The theory of electronegativity lies in entire inorganic chemistry. The more electronegative an atom, the more it seeks electrons. If one atom is more electronegative than others, it can form an ionic bond or a polar covalent bond.

During mitosis, the ________ breaks down and the duplicated ___________ are separated and evenly distributed to opposite sides o
JulsSmile [24]
During mitosis, the <em />nuclear membrane breaks down and the duplicated chromosomes are separated and evenly distributed to opposite sides of the cell. Cytokinesis involves the division of the cytoplasm and the organelles that are contained within. 

This describes the process of cell division. All of these events happen in the M phase of mitosis. The breaking down and fragmentation of the nuclear membrane to expose the genetic material is in the prophase. The next phase is the metaphase when the duplicated chromosomes align in a straight line (metaphase plate). Anaphase involves the separation of chromatids and by the time the chromatids reach the opposite side then the cell enters telophase. Lastly, cytokinesis involves restoration of the nuclear membrane, division of the cytoplasm, and production of two daughter cells.
