A. Size, because it would determine if the molecule can fit though the pores.
Chlamydia is a common sexually transmitted disease caused by a bacteria called chlamydia trachomatis which can affect both sexes. In some pregnancies, this disease can cause premature labor among women. Moreover, it can cause chlamydia-related diseases among babies such as eye and respiratory tract infections. It is also a leading cause of early infancy pneumonia and pink eye or conjunctivitis. Therefore, Chlamydia is the sexually transmitted disease that can cause the aforementioned abnormalities.
From the options, the true statements about glycocalyx are : ( 1 ) and ( 3 )
- All animal cell have a glycocalyx ( 1 )
- The glycocalyx helps one cell adhere to another ( 3 )
Glycocalyx is a layer of macromolecules attached to the cell membrane of cells. they perform several functions like protecting the cell from the entrance of pathogens and also providing a medium for cell to cell interaction.
Glycocalyx are found in cells of living organisms, and they are made up of glycosaminoglycans, proteoglycans and glycoproteins as well. hence they are not comprised mostly of proteins.
Hence we can conclude that the true statements about glycocalyx are : All animal cell have a glycocalyx and the glycocalyx helps one cell adhere to another

Meiosis is important for organisms since it allows for genetic variation among organisms.
<h2>Further Explanation</h2><h3>Cell division</h3>
- Cell division is the process in which cells undergo division to form other new cells.
- There are two types of cell division;
<h3>Mitosis Division </h3>
- Mitosis is a type of division in which a parent cell undergoes division to yield two daughter cells that are similar to the parent cells.
- The daughter cells have equal number of chromosomes as the parent and are identical to the parent.
- This type of cell division normally occurs in somatic cells of organisms and facilitates growth and development of organisms.
<h3>Meiosis division</h3>
- Meiosis division is a type of division that occurs in gamete cells where a parent cell divides into four daughter cells that differ from the parent cells in terms of the number of chromosomes.
- In meiosis the daughter cells have half the number of chromosomes as the parent cells.
- Meiosis occurs in the gamete cells and facilitates sexual reproduction in living organisms.
- Meiosis occurs in two phases, that is, meiosis I and meiosis II
- During the process of meiosis several processes occurs that cause genetic variation among organisms.
- These processes include, crossing over, independent assortment of genes, among others.
<h3>Crossing over </h3>
- Cross over is the process that occurs during the prophase I phase of the first stage of meiosis known as meiosis I.
- During the process of crossing over, genetic material is exchanged between homologous chromosomes which enhances the genetic variation in organisms.

Answer:
CGTATC - DNA complementary strand- GCATG
CTTTCAAG- DNA complementary strand-GAAAGTTG
GAGACTTAC-DNA complementary strand-CTCTGAATG
Explanation:
Remember that the complementary sequence will be based on base pairing for DNA, so the A will pair with T, C with G
