Answer:
The testes produce spermatocytes (sperm) while ovaries produce oocytes (ova)
Explanation:
They are produced by the process of meiosis I on the parent cell than meiosis II. In the testes, the process is called spermatogenesis while in ovaries the process is referred as oogenesis. These processes are regulated by gonadotropins Follicle Stimulating Hormone and Luteinizing Hormone.
Answer:
Explanation:
leptoteno es el estado inicial de la profase I en la meiosis.

los cromosomas aparecen como largos filamentos
cada cromosoma esta constituido por 2 cromatidas
Answer:
The answer is C. its sequence of amino acids.
The protein's shape is influenced by its sequence of amino acids or primary structure.
Explanation:
The primary structure of a protein molecule is dependent on the amino acid chain sequence it has. The amino acid chain's <u>linear</u> structure is composed of <u>covalently bonded</u> amino acids via peptide bonds. This serves as the <u>overall backbone </u>of the protein.
<h3>Additional notes: </h3>
Secondary structure of protein
It defines the 3-dimensional shape of the<u> locally folded polypeptide</u>. They come in two forms, the alpha helices and beta sheets. During the formation of the primary structure, acidic and basic amino residues may cause kinks and turns, re-configuring the 3-D shape of the local polypeptide.
Tertiary structure of protein
This determines the overall 3-dimensional structure of the protein. The structure is due to the <u>linking of the R groups</u> of the related amino acids, <u>hydrophobic bonds</u>, and <u>disulfide bonds</u>. These bonds are <u>highly stable</u> and are not easily changed or destroyed.
Quaternary structure of protein
It is a structure that consists of multiple folded polypeptide chains or subunits. This allows the protein to have m<u>ultiple functions</u>. <u>Non-covalent forces</u> keep these structures together, making it <u>prone to rapid conformational changes.</u>
Answer:
An absorption spectrum illustrates the spectrum of light or electromagnetic radiation absorbed by the plant. This relies upon the molecular and cellular build-up of the plant. An action spectrum illustrates the spectrum of electromagnetic radiation most efficient for photosynthesis.
The action spectrum of photosynthesis monitors the absorption spectrum of chlorophyll. The absorption spectrum suggests that how much of each wavelength chlorophyll will captivate, while the action potential can indicate to us about the wavelengths that are most operative for photosynthesis.
