Which finding/findings would be consistent with aplastic anemia: a. reduced hematocrit b. reduced reticulocyte count c. reduced fibrinogen d. a and b e. a,b and c
Answers
(e) a,b and c. Reduced hematocrit: Aplastic anemia is a type of anemia in which the bone marrow fails to produce enough new blood cells.
The decreased number of red blood cells causes the oxygen level to decrease in the body, leading to anemia. Hematocrit is a measurement of the volume of red blood cells in relation to the total volume of blood. The hematocrit level is usually low in aplastic anemia.Reduced reticulocyte count: The bone marrow produces reticulocytes that are immature red blood cells. The reticulocyte count is usually low in aplastic anemia, indicating a failure of the bone marrow to produce new blood cells.
Reduced fibrinogen: Fibrinogen is a protein that helps in blood clotting. Reduced fibrinogen levels in the blood can lead to bleeding problems and an increased risk of developing blood clots. Therefore, it is a finding consistent with aplastic anemia.Therefore, the findings that are consistent with aplastic anemia are reduced hematocrit, reduced reticulocyte count, and reduced fibrinogen.

How does the lipid portion help maintain water concentration on each side of the bilateral?
Answers
Answer:
Explanation:The phospholipid bilayer formed by these interactions makes a good barrier between the interior and exterior of the cell, because water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane. Can water cross the plasma membrane at all?
It also helps the cell move things in and out. The cell membrane is made of what is called a phospholipid bilayer, which means it has two layers of phospholipids. ... This allows the phosphates to be exposed to water, either in the cell or the environment, while the lipids are protected from water Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible.

Trace what happens to a piece of bread as it enters the mouth to the large intestine. Be sure to mention each organ of the digestive system and what happens to the bread in each part.( This is an essay question )put in high school level)
Answers
Answer:
The mechanical digestion begins with the with and the tongue whch breaks the bread,press it staging the soft palate Chemical digestion follows with the saliva-enzyme salivary amylase. The enzymes acts on starch in the bread and converts this to Maltose.A diassacharides , and oligosaccharides This ends CHO digestion in the mouth.
The digesting bread is push by waves of contraction of the horizontal and vertical muscles of the oesophagus.This wavelike contractions is called Peristalsis.
This is push down into the stomach through the opening of the upper sphincter.In the stomach the pH of the amylase enzyme in the bread now called chyle is reduced(neutralized) by the HCL of the medium.No digestion occurs in the stomach.
In the small intestine is the enzyme pancreatic Maltase,secreted from the pancreas.This enzyme catalysis the hydrolysis of the maltose ( diasaccharides,) to some monosaccharides subunits.At this stage the digesting bread is called chyme,with its maltose content.
Still in the small intestine maltase(from the epithelial brush borders of the small intestine) converts the hydrolysis of maltose to the sub units of glucose,fructose, and galactose,making the end of CHO digestions in the small intestine.
The large intestine is for absorption of water and storage and removal of undigested foods from the body.It is made up of the cecum, colon, rectum and anus.As unwanted food passes through this.,massive water absorption occurs, it contents and structure is change to stool as it escapes through the anus, as faeces.

Why is the conservation of genetic information during DNA replication important?
Answers
Answer:
please give me brainlist and follow
Explanation:
The first method, conservative replication, had the DNA strand completely conserved. Two old DNA strands stuck together, and two new DNA strands were synthesized and stuck together. The old and new DNA did not bind to one another. Another method, dispersive replication, did have old and new DNA binding to each other.
The conservation of genetic information during DNA replication is important, as DNA replication is the process by which cells make copies of their genetic material that pass on to the next generation.
What is the significance of the conservation of genetic materials?The conservation of genetic information during DNA replication is important for maintaining the stability of the genome, preventing the accumulation of harmful mutations, and allowing evolution to occur. The genetic information must be accurately passed down from generation to generation and is also useful adapt to changing environmental conditions.

The Marcus family exhibits an inheritance pattern consistent with X-linked recessive inheritance, which cannot be explained by Mendel's original model of inheritance.
Mendel's model of inheritance was based on the idea of dominant and recessive traits, with each parent contributing one allele to their offspring. However, we now know that inheritance can be more complex than this, with multiple genes and environmental factors influencing the expression of traits.
The Marcus family has a history of red-green color blindness, with several members of the family affected. This inheritance pattern cannot be explained by Mendel's original model, as it suggests that a single gene with dominant and recessive alleles is responsible for color vision.

If an individual has a dominant allele on one chromosome but a recessive allele at the same position on the homologous chromosome, he or she is genetically __________ for the trait.
Answers
If an individual has a dominant allele on one chromosome but a recessive allele at the same position on the homologous chromosome, he or she is genetically heterozygous for the trait.
Heterozygous individuals have two different alleles for a particular gene, one dominant and one recessive. The dominant allele is expressed and determines the phenotype, while the recessive allele is present but not expressed. In this case, the individual has one chromosome with a dominant allele and one chromosome with a recessive allele at the same position, resulting in a heterozygous genotype. The phenotype will be determined by the dominant allele.

A single-stranded RNA molecule of sequence 5'-AAAAAAA-3' is treated with an enzyme that hydrolyzes the bonds between the adenines and the sugar groups. What is left
Answers
When a single-stranded RNA molecule with the sequence 5'-AAAAAAA-3' is treated with an enzyme that hydrolyzes the bonds between the adenines and the sugar groups, the result is a mixture of nucleotides and sugars. The enzyme that catalyzes this hydrolysis is known as an RNase or ribonuclease.
Specifically, the RNase will cleave the phosphodiester bonds between the 5'-carbon of one ribose sugar and the 3'-carbon of the next ribose sugar in the RNA molecule, releasing a nucleotide monophosphate and leaving the ribose sugar with a free 3'-OH group.
In the case of the RNA molecule 5'-AAAAAAA-3', all of the nucleotides are adenines, so the result of the hydrolysis will be a mixture of adenine nucleotide monophosphates and ribose sugars with free 3'-OH groups.
This mixture can be further analyzed by methods such as high-performance liquid chromatography (HPLC) or capillary electrophoresis to separate the individual components and determine their identities and quantities.
The hydrolysis of RNA by RNase enzymes is an important step in the degradation of RNA and in RNA processing events in cells.

Answers
It is true that evolution occurs when new traits accumulate, but it is false that evolution only occurs when new traits accumulate. Evolution can occur when traits are lost. Some lineages adapt to their environments by becoming less complex over time.
Evolution is a process of change in the inherited traits of a population over time. This change can occur through the accumulation of new traits, but it can also occur through the loss of traits.
For example, some lineages of cave-dwelling animals have lost their eyesight over time because it was not necessary for survival in their environment. Similarly, some lineages of animals have become less complex over time, such as parasites that have lost certain body structures because they are not needed in their host-dependent lifestyle. Therefore, it is important to understand that evolution can occur through both the accumulation and loss of traits.

The researcher who conducted an investigation on a blood disease carried by birds found out that the organism is unicellular and has a nucleus, cell wall, and the ability to produce spores. Based on this information, the organism belongs to the Kingdom Fungi.
The kingdom Fungi consists of unicellular and multicellular organisms that lack chlorophyll and reproduce asexually and sexually by forming spores. They are heterotrophic organisms, which means they depend on other organisms for their food. Fungi cells have a cell wall made up of chitin, which provides strength and rigidity to the cell wall. The cytoplasm of the fungal cells contains many specialized organelles, including nuclei, ribosomes, mitochondria, and Golgi bodies that carry out various metabolic activities.
The researcher's findings suggest that the organism is a unicellular fungus with a nucleus, cell wall, and the ability to produce spores. Spores play a crucial role in the fungal life cycle, as they allow the organism to reproduce and spread to new habitats. These spores can be transported by wind, water, or other organisms to colonize new areas.

what is the effect of Dideoxycytidine on the replication of viral DNA.
Answers
Answer:
Several 2',3'-dideoxy-3'-thiapyrimidine nucleosides were studied for their ability to inhibit hepatitis B virus (HBV) DNA replication in a HBV-transfected cell line (2.2.15). 2',3'-Dideoxy-3'-thiacytidine (SddC) and 5-fluoro-2',3'-dideoxy-3'-thiacytidine(5-FSddC) were found to be the most potent anti-HBV compounds of those examined. Both compounds resulted in nearly complete cessation of viral DNA replication at 0.5 microM, as monitored by the absence of both intracellular episomal and secreted viral DNAs. The HBV-specific RNAs were not reduced at concentrations that completely blocked HBV DNA replication, suggesting that the inhibitory target is HBV DNA synthesis. The antiviral action of SddC and 5-FSddC was reversible. The concentration of SddC and 5-FSddC required to inhibit 50% of 4-day cell growth in culture was 37 microM and more than 200 microM, respectively. Unlike 2',3'-dideoxycytidine, these two compounds do not affect mitochondrial DNA synthesis in cells at concentrations lower than that required to inhibit cell growth. In view of the potent and selective antiviral activity, both SddC and 5-FSddC should be further evaluated for the treatment of human HBV infection.
