Answer:
binary fission
Explanation:
The process by which Prokaryotic cells divide is known as binary fission.
prokaryotic cells are cells that do not have a nucleus and replicate through the process of binary fission
first step
A copy is made of one side of the DNA segment where a particular gene is located. This copy is transferred to the cytoplasm.
second step?
This mirror like copy of a DNA segment is called messenger RNA (mRNA)
third step?
Each group of three bases on the mRNA segment codes for one amino acid.
fourth step?
The mRNA segment is fed through the ribosome.
fifth step?
Molecules of transfer RNA (tRNA) deliver amino acids from the cytoplasm to the ribosome.
sixth step?
The amino acids are dropped off at the ribosome.
seventh step?
The amino acids are joined to make a protein. Usually, one protein is produced for each gene.
Answer:
a network of proteins that holds homologues together.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
The synaptonemal complex is a network of proteins that holds homologues (homologous chromosomes) together.
Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.
Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;
I. SC protein-1 (SYCP1).
II. SC protein-2 (SYCP2).
III. SC protein-3 (SYCP3).
In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.
<span>The
correct answer is pharyngeal pouches.</span>
<span>All
chordates for at least some period of their life have pharyngeal pouches (pharyngeal
slits). Those are the openings in the pharynx with the function in the
filter-feeding. Pharyngeal slits are present during the embryonic stages of
tetrapod development. They <span>develop into gill arches (bony fish) and into the jaw and inner ear (terrestrial
animals).</span></span>
Answer:
21 m
Explanation:
La energía potencial de un cuerpo es la energía que posee el cuerpo en virtud de su posición.
La energía potencial se da como;
E = mgh
Dónde;
m = masa del cuerpo
g = aceleración por gravedad
h = altura del cuerpo
Aquí necesitamos obtener la altura del cuerpo.
h = E / mg
h = 10500/50 * 10
h = 21 m
