2. If a nucleus has 8 chromosomes, how many chromosomes will be present after Telophase I? 3. What advantage does crossing-over have in reproduction? 6. Compare and contrast spermatogenesis and oogenesis (where do they occur, how many gametes are formed, when do they develop, etc):
Answer:
Telophase I: 8 chromosomes composed of two sister chromatids
Crossing over refers to the mechanism of recombination, this process being characterized in that increases the genetic variation
Spermatogenesis refers to the mechanism of formation of male gametes (sperms), while oogenesis is the process of formation of female gametes (oocytes)
Explanation:
Telophase I is the final step in meiosis I. During telophase I, the nuclear membrane is formed around the decondensed set of chromosomes and the nucleoli reappear.
Spermatogenesis refers to the process by which haploid male germ cells (sperms) are generated within the seminiferous tubules in the testis, while oogenesis refers to the process of differentiation of the female egg cells (ova or oocytes) in the ovaries. Spermatogenesis is known to produce small and motile spermatic cells, while oogenesis is known to produce bigger non-motile oocytes.

Answer:
Transcription begins in the nucleus when RNA polymerase unzips a DNA molecule.
RNA nucleotides align themselves to complementary base pairs and in this manner messenger RNA is formed.
In eukaryotes must be processed before it leaves In the nucleus.
One end is modified with the addition of a cap and the other end is modified with the addition of a poly-A tail. Some sections called introns are edited out, leaving only exons remaining.
Then, the messenger RNA leaves the nucleus and enters the cytoplasm where it awaits the process of translation
Explanation:
Transcription is the process in which DNA becomes RNA. In this protein synthesis, transcription occurs in the nucleus while translation in the cytoplasm. In the first one, which is transcription, a messenger RNA is produced. In the seceond one, an amino acid sequence is produced in the ribosomes.
*Take into account there were two options missing that I added because they were the only correct answer. "In eukaryotes must be processed before it leaves In the nucleus" the only right answer is eukaryotes, because prokaryotes don't have nucleus. The other situation was in "Then, the messenger RNA leaves the nucleus and enters the cytoplasm where it awaits the process of translation" the only option given was "transcription". The right answer is "translation" because this one occurs in the cytoplasm, and transciptrion in the nucleus.
The cardiac tissue has fewer T tubules and store less calcium than skeletal muscle. What is the outcome of these two traits
Answer:
The slow arrival of contraction or the slow onset of contraction.
Explanation:
The T tubules function in the transformation of the action potential from the sarcolemma to the sarcopasm reticulum.
In the skeletal muscles, it is located at the junction of the A and I bands but in the cardiac muscles, it is located only at the z discs thus giving rise to to T tubules.
The cardiac muscles also do not possess as much calcium as the skeletal muscles thus, its calcium ion must come from outside producing the slow arrival of contraction or the slow onset of contraction.
The cardiac tissue has fewer T tubules and stores less calcium than skeletal muscle, thereby the onset for muscle contraction is SLOWER in the heart than in skeletal muscle.
The sarcolemma is the plasma (excitable) membrane of muscle cells, which are surrounded by endomysial connective tissue.The T-tubules are invaginations of the sarcolemma that enter into the muscle cell in order to form interconnected networks.These tubules (T tubules) store intracellular calcium ions under the supervision of membrane depolarization through a voltage sensor channel (i.e., DHPR).In conclusion, the cardiac tissue has fewer T tubules and stores less calcium than skeletal muscle, thereby the onset for muscle contraction is SLOWER in the heart than in skeletal muscle.

During osmosis Group of answer choices pure solvent and a solution both diffuse at the same time through a membrane.
During osmosis A) pure solvent diffuses through a membrane but solutes do not. B) pure solutes diffuse through a membrane but solvent does not. C) pure solvent and a solution both diffuse at the same time through a membrane. D) gases diffuse through a membrane into a solution and build up pressure.
Answer:
Explanation:A.
The net movements of solvent from the region of higher water potential (solvent) to a region of lower water potential(solute) through a semipermeable membrane is called osmosis. It is a peocess where the solute dissolved in the solvent and the resulting solution pass the selective permeable membrane,A selective permeable is the type which allows water,gases, and non polar molecules to pass through, but restrict polar and other large molecules through its walls.
Generally during osmosis,the water molecules and solute molecules interacts.These interaction ,due to dipole dipole effects of the water molecules, reduced the pressure of water on the solute in solution .Consequently, the water molecule of the pure water (the solvent )exerts more pressure on the weaker solution i,e higher water potential
Hence,this pressure forces water molecules across the semi permeable membrane,from higher water potential to lower water potential.It is the major biological process of plants and animals.
list the uses of gibberelin
snap id is in my bio
Answer:
A group of plant hormones, which are accountable for growth and development is gibberellins. These hormones play an essential part in the initiation of seed germination. A lesser quantity, these hormones can play an essential function in elevating the speed of germination, and they instigate cell elongation so that the plants grow taller. The following are the essential uses of gibberellins:
1. Promote flowering
2. End seed dormancy
3. Increase the size of the fruit.
For the seeds to germinate, there is a need for seed dormancy to end, and this can be done with the use of gibberellins. The hormone also promotes the process of flowering, which helps in the production of more fascinating and larger specimens of flowers.
The flowering process also influences the rate of the growth of fruits. Gibberellins are also used in the generation of seedless fruits. The spraying of the hormone helps to enhance the size of the fruit.
