Carriers of the sickle-cell allele have a genetic advantage because they have ____
Carriers of the sickle-cell allele have a genetic advantage because they have increased resistance to malaria.
The sickle cellular anemia trait is observed on a recessive allele of the hemoglobin gene. because of this you ought to have two copies of the recessive allele one out of mom and one from to have the condition. human beings one dominant and one recessive replica of the allele might not have sickle cell anemia.
Sickle cellular disorder is caused by a mutation within the hemoglobin-Beta gene observed on chromosome. Hemoglobin transports oxygen from the lungs to other components of the body. red blood cells with regular hemoglobin hemoglobin-Aare clean and spherical and float via blood vessels.
Sickle mobile sickness is a hereditary sickness visible most malaria amongst human beings of African ancestry. as a result of mutations in one of the genes that encode the hemoglobin protein, the disorder is inherited as an autosomal recessive trait.

FILL THE BLANK. in females diploid primordial germ cells that give rise to primary oocytes by mitosis are called ___
In females, diploid primordial germ cells that give rise to primary oocytes by mitosis are called oogonia.
Oogonia are the specific cells in the female reproductive system that undergo mitosis to produce primary oocytes. During early development, primordial germ cells migrate to the developing gonads and differentiate into oogonia. These oogonia are diploid cells, meaning they contain a complete set of chromosomes.
Through mitosis, oogonia undergo a series of divisions, resulting in the production of primary oocytes. Mitosis is a process of cell division in which one cell divides into two identical daughter cells, each containing the same number of chromosomes as the parent cell. In this case, oogonia undergo mitotic divisions to increase their numbers and produce a pool of primary oocytes.

what is the correct order of protein production?
1) ribosome
2) endoplasmic reticulum
3) secretory vesicles
4) golgy apparatus
a) 1,2,3,4
b) 2,4,3,1
c) 1,2,4,3
d) 3,2,4,1
Answer:
The correct order of protein production is:
c) 1,2,4,3
Ribosome: Protein synthesis begins in the ribosomes, which are located either in the cytoplasm or attached to the endoplasmic reticulum.
Endoplasmic Reticulum: After the initial stages of protein synthesis in the ribosomes, the newly synthesized protein is transported into the endoplasmic reticulum (ER) for further processing and modification.
Golgi Apparatus: The proteins synthesized in the ER undergo further processing and modifications in the Golgi apparatus. This includes sorting, packaging, and modifying the proteins to their final functional forms.
Secretory Vesicles: Once the proteins are properly processed and modified in the Golgi apparatus, they are packaged into secretory vesicles. These vesicles transport the proteins to their destination, such as the plasma membrane for secretion outside the cell.
Therefore, the correct order is 1, 2, 4, 3.
Answer:
The correct order of protein production is ribosome, endoplasmic reticulum, Golgi apparatus, and secretory vesicles. So the correct answer would be c) 1,2,4,3.
Many proteins destined for the endoplasmic reticulum, the Golgi apparatus, lysosomes, the plasma membrane, and secretion from the cell are synthesized on ribosomes that are bound to the membrane of the endoplasmic reticulum. The Golgi apparatus then distributes these proteins and lipids that it receives from the ER.
Fermentation does not produce ATP. Why is fermentation such an important process in cells
Answer:
In humans we go through Lactic Acid Fermination
Explanation:
It is important because after glycolysis we have the elctron carrier NAD+ reduced to NADH and we cant continue glycolysis until we have NADH back to NAD+ so all lactic acid fermintation does it removed the electron and allow glycolysis to continue. It should be noted that fermintation occurs when there is no oxygen / not enough to continue cellular respiration so we rely on glycolysis to produce very little ATP while oxygen is replenished,
In a species of chickens, incomplete dominance between alleles for black (B) and white(w) feathers
is observed. Heterozygotes are blue.
• If two blue chickens are crossed, what is the probability that the offspring will be blue.
Answer:
1/2
Explanation:
This question involves a single gene coding for feather color in chickens. The black allele (B) is incompletely dominant over the white allele (W). This means that the allele B will not mask the phenotypic expression of allele W, hence, a third intermediate blue phenotype (BW) will be produced.
According to the question, if two blue chickens are crossed i.e. BW × BW, the gametes B and W will be produced by each parent. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
BB, BW and WW in the ratio 1:2:1
BB is black, BW is blue, WW is white. Hence, the probability of producing a blue chicken from this cross is 1/2.

transmission of an action potential across a synapse invovles the release of neurotransmitters by the presynaptic neuron. the arrival
Transmission of an action potential across a synapse involves the release of neurotransmitters by the presynaptic neuron the arrival: of an action potential at the presynaptic neuron triggers the release of neurotransmitters."
The process of transmitting an action potential across a synapse involves several steps.
When an action potential reaches the presynaptic neuron, it depolarizes the membrane, causing voltage-gated calcium channels to open.
The influx of calcium ions into the presynaptic terminal triggers the release of neurotransmitters from synaptic vesicles into the synaptic cleft.
Neurotransmitters are chemical messengers that transmit signals from the presynaptic neuron to the postsynaptic neuron or target cell.
They are released into the synaptic cleft and diffuse across the small gap between the presynaptic and postsynaptic membranes.
Upon reaching the postsynaptic membrane, neurotransmitters bind to specific receptors, either ion channels or G-protein coupled receptors. This binding can either excite or inhibit the postsynaptic neuron, depending on the neurotransmitter and receptor type.
The neurotransmitters that are not bound to receptors are either taken back up into the presynaptic neuron through reuptake mechanisms or enzymatically degraded in the synaptic cleft.
Overall, the release of neurotransmitters by the presynaptic neuron is a crucial step in the transmission of an action potential across a synapse, allowing for the communication and integration of signals between neurons.

if the cellular response to a hormone caused an increase in rna synthesis, the hormone most likely was a steroid hormone. true or false
True. Steroid hormones are lipid-soluble and can easily cross the plasma membrane of cells.
Once inside the cell, they bind to specific receptors located in the cytoplasm or nucleus, forming a hormone-receptor complex that then binds to DNA and modulates gene expression. This can result in the activation of specific genes that lead to the cellular response, which in this case, is an increase in RNA synthesis. The increase in RNA synthesis is a result of the activation of genes that encode for RNA polymerases, enzymes that catalyze the synthesis of RNA molecules. Other hormones, such as peptide hormones, cannot directly affect gene expression as they cannot cross the plasma membrane and require specific receptors on the cell surface to exert their effects. Therefore, if the cellular response to a hormone caused an increase in RNA synthesis, the hormone most likely was a steroid hormone.

the only source of water for marine iguanas is seawater with an osmolarity of 1000 mosm. marine iguana body fluids are normally 370 mosm. marine iguanas drink seawater, but their blood osmolarity does not increase. what osmotic challenges must they overcome?
The osmotic challenge the marine iguanas must overcome is: increased concentration of body fluids by salt gain.; option E is correct.
What is the osmolarity of a solution?The osmolarity of a solution is the number of dissolved particles of a solute per liter of solution. It is a way to express the concentration of solution.
The unit of osmolarity is osmol/L or mosm/L.
The higher the number of solute particles dissolved in a given volume of solvent in liters, the higher the osmolarity of the solvent will be.
Considering the given situation where the marine iguana drinks sea water which is of higher osmolarity than blood, the marine iguana has to find a way to ensure that the excess salt is removed. This is because, due to the higher osmolarity of the seawater compared to the marine Iguana's blood, water molecules would tend to move out from the cells in order to dilute the seawater taken in by the iguana. Hence, the risk of dehydration is high.
