There is only 50 % chance that offspring have a sleep defects. The simplest test to distinguished between the two possibilities is the complementation test.
When two recessive organism are crossed then mutation are in the same gene , both copies of gene will be mutant in F1 offspring and they will exhibit the same phenotype as their parents.
The exact mutation may be different but both allele of single gene are mutant and the recessive phenotype will be observed.

When b cell receptors are brought close enough together to cause b cells to be activated, the brcs are said to be:_____.
When B cell receptors are brought close enough together to cause B cells to be activated, the BRCs are said to be Crosslinked.
What are B cell receptors?
The B cell receptor (BCR) is a transmembrane protein on the surface of a B cell. A B cell receptor is composed of a membrane-bound immunoglobulin molecule and a signal transduction moiety. The former forms a type 1 transmembrane receptor protein, and is typically located on the outer surface of these lymphocyte cells. Through biochemical signalling and by physically acquiring antigens from the immune synapses, the BCR controls the activation of the B cell. B cells are able to gather and grab antigens by engaging biochemical modules for receptor clustering, cell spreading, generation of pulling forces, and receptor transport, which eventually culminates in endocytosis and antigen presentation. B cells' mechanical activity adheres to a pattern of negative and positive feedbacks that regulate the quantity of removed antigen by manipulating the dynamic of BCR–antigen bonds directly. Particularly, grouping and spreading increase the relation of antigen with BCR, thereby proving sensitivity and amplification. On the other hand, pulling forces delinks the antigen from the BCR, thus testing the quality of antigen binding.To learn more about B cell receptor: https://brainly.com/question/15076966

Following meiosis I, the daughter cells are ________; following meiosis II, the daughter cells are ________; and following fertilization and mitosis, the daughter cells are ________.
Following Meiosis I, the daughter cells are Haploid. Following Meiosis II, the daughter cells are Haploid and following Fertilization and Mitosis, the daughter cells are Diploid.
In a diploid cell containing a complete set of chromosomes and DNA content, After Meiosis I, the number of chromosome reduces by half thereby producing two daughter cells that are haploid which is termed as the Reductional Division due to the reduction in the number of chromosome and reduction of DNA content by half. Hence, the cell becomes Haploid after Meiosis I.
After Meiosis II, the number of chromosomes remains half as compared to the Diploid cell and only the DNA content reduces to one fourth as compared to the diploid cell. It is similar to Mitosis or Equational Division since no change occurs in the chromosome number as compared to the daughter cell obtained after Meiosis I. Hence, the cell remains Haploid after Meiosis II
After Fertilisation of two haploid cells formed after completion of Meiosis, the cell become Diploid (due to the fusion) containing complete set of chromosome and DNA content. After Mitosis of the newly formed Diploid cell, the number of Diploid cells increases due to the formation of two daughter cells produced continuously. No change in the chromosome number or DNA content occurs.

Gluconeogenesis uses the same enzymatic reactions of glycolysis except for the?
With the exception of the three irreversible events in glycolysis, gluconeogenesis utilizes the same enzyme processes as glycolysis.
Glycolysis & Gluconeogenesis:
In contrast to gluconeogenesis, which is crucial for sustaining blood glucose levels during hunger, glycolysis is a catabolic process that hydrolyzes glucose to produce energy and biosynthetic intermediates.In the catabolic route of glycolysis, glucose is converted to pyruvate. The anabolic route known as glucose conduction produces glucose from non-carbohydrate sources like glycerol and glucogenic peptides. Pyruvate turns into glucose during the process of gluconeogenesis.The general consensus would be that glycolysis and gluconeogenesis don't happen at the same time within similar cells, instead, that metabolic circumstances or allosteric effectors that drive flux along one pathway repress flow in the other direction.Original question:

Breathing into and out of a paper bag for a long period of time will lead to?
Breathing into and out of a paper bag for a long period of time will lead to respiratory acidosis.
What is respiratory acidosis?When the lungs are unable to expel all of the carbon dioxide the body produces, a condition known as respiratory acidosis develops. Body fluids, particularly the blood, become too acidic as a result.The main causes of respiratory acidosis are inadequate ventilation and carbon dioxide buildup. The main issue is an increase in arterial carbon dioxide partial pressure (pCO2) and a decline in the arterial bicarbonate to arterial pCO2 ratio, which causes a drop in blood pH.When there is acute respiratory acidosis, the body initially tries to make up for it. If the acidosis lasts more than 12 hours, a reaction known as metabolic compensation2 takes place. By increasing the release of hydrogen ions through ammonium, the kidneys will lower the blood's acidity.Too much carbon dioxide in the body can result in general symptoms including headache, exhaustion, and twitching muscles. Frequently, it goes away fast on its own. But in cases of severe hypercapnia, the body is unable to return to a stable CO2 level, and the symptoms are more severe.

The arrangement of subunits in the pdh (pyruvate dehydrogenase) complex ensures that?
The arrangement of subunits in the pdh (pyruvate dehydrogenase) complex ensures that in the inner mitochondrial membrane.
By turning pyruvate into acetyl-coenzyme A, the pyruvate dehydrogenase complex (PDHc) connects glycolysis to the citric acid cycle. The pyruvate dehydrogenase complex (PDHc), consists of the three enzymatically active subunits pyruvate dehydrogenase, dihydrolipoyl transacetylase, and dihydrolipoyl dehydrogenase, which links the citric acid cycle and subsequent oxidative phosphorylation to the pathways for glycolysis, gluconeogenesis, and lipid and amino acid metabolism. E1 is a part of PDH and catalyzes pyruvate's oxidative decarboxylation. Dyhydrolipoyl transacetylase, also known as E2, catalyzes the addition of an acetyl group to coenzyme A to produce acetyl CoA. The oxidative decarboxylation of pyruvate, a -keto acid, by the pyruvate dehydrogenase complex produces carbon dioxide (CO2) and the acetyl group of acetyl-coenzyme A or acetyl-CoA with the release of two electrons, carried by NAD, in five successive processes.

When is cell-to-cell communication particularly important in regulating gene expression?
Answer:
during embryonic development
Explanation:
Cell-to-cell communication is particularly important in regulating gene expression during the embryonic development.
Cells in the developing embryo are constantly communicating with their neighbors. The molecules used by them in sending and receiving signals are crucial for normal embryogenesis. Various intracellular signaling pathways have been discovered, some of which are activated in response to secreted growth factors.
However, a few important signaling pathways are used often during embryonic development to regulate various cellular processes that shape the developing embryo.
Embryonic development is marked by the thorough regulation of cellular functioning so that the cells proliferate, migrate, differentiate, and form tissues at the correct place and time. These processes are genetically controlled and depend both on the history of cells, their lineage, as well as on the activities of signaling pathways, which coordinate the cell interactions leading to organogenesis.

Aquatic animals are extremely harmful to DDT. DDT has an impact on a number of aquatic animal systems, including the heart and brain. Fish are extremely harmful to DDT.DDT is difficult for fish to detect in water. When an animal eats food that contains DDT residue, the DDT builds up in the animal's tissue through a process known as bioaccumulation.
