Assessment of genetic risk for distribution of total interstitial white matter neurons in dorsolateral prefrontal cortex: role in schizophrenia
It has been demonstrated that tissue engineering scaffolds with oxygen generating components can boost the amount of oxygen and cell viability under some circumstances. In this study, direct-write assembly (robocasting) was used to create biphasic calcium phosphate (BCP) scaffolds with a composition of 60% hydroxyapatite (HA) and 40% beta-tricalcium phosphate (-TCP), which have demonstrated a high potential for bone tissue engineering applications. The three-dimensional (3D) printed scaffolds were then dip-coated with various concentrations of calcium peroxide (CPO), an oxygen releasing agent, and employed for in situ oxygen synthesis in the implanted sites. CPO was contained within a polycaprolactone (PCL) matrix. Different methodologies were used to describe the created scaffolds' morphology, content, and structure.

Explanation:
In a test-cross, an individual that exhibits a dominant trait but has an unknown genotype is mated with an individual that is homozygous recessive.
To assess if an organism expressing a dominant characteristic is homozygous or heterozygous, a test cross can be used.
Back crosses are made between F1 generation plants and any of the parent plants, whereas test cross is made between F1 generation plants with dominant phenotypes and the homozygous recessive parent.
The phenotypes of the children can be used to identify the unknown genotype. If combining the recessive phenotype individual with the unknown dominant phenotype (PP or Pp genotype) results in solely dominant phenotypes (no recessive), then the unknown individual is homozygous dominant.
No matter if you are examining one gene or several genes, test crosses work on the same principle: you are pairing a person with a dominant phenotype but an unknown genotype with a person who is homozygous recessive for all relevant genes.

What is the most likely effect of a mutation that changes the repeat sequence found in terc from 3’-cccaau-5’ to 3’-ucaggacg-5’?.
If the repeat sequence of telomere changes from 3’-cccaau-5’ to 3’-ucaggacg-5’ due to any mutation in TERC gene then the telomerase enzyme will be unable to attach to the 3' overhung of the telomere sequence and cannot elongate new DNA strand [telomeric part]. As a result, the telomeres of chromosomes cannot be elongated and the entire chromosome or the cell will be lost after a few rounds of division.
Telomere: They are short repeating sequences found at the end of the chromosome whose function is to save the chromosomes from degradation. But after each round of replication, the length of the telomeres becomes shorter than the previous and after a certain number of cell divisions, the telomeres become so short that they trigger the cell to stop dividing or to self-destruct (undergo apoptosis).
So, to prevent the shortening of telomeres, the TERC gene codes a telomerase enzyme which is a type of reverse transcriptase made up of two components: an RNA part that is complementary to the repeated telomeric sequence and a protein part that can add the nucleotides to the 3' end of the telomere.
After every cell division, the telomerase enzyme gets attached to the 3' end of the shortened telomere end and synthesizes the complementary DNA to the RNA part of the enzyme until the length of the telomere is restored again.

LDLs contain _______. LDLs contain _______. steroid hormones cholesterol protein cholesterol and protein cholesterol, protein and steroid hormones
The correct option is (c) LDL consists of cholesterol and protein.
One of the five main categories of lipoproteins, low-density lipoprotein (LDL), transports cholesterol throughout the body to the areas where it is required for cell repair and deposits it inside the artery walls. They need to be bound to proteins in order to pass through the hydrophilic blood.
The hydrophobic core of the LDL particle is made up of fatty acid esters of cholesterol, while the outer membrane is made up of unesterified cholesterol. The membrane contains a single copy of the hydrophobic apo-B protein, which facilitates the binding of LDL particles to particular cell-surface receptors.
Hence, LDL consists of cholesterol and protein.

Describe the structure of a neuron. Include the cell body, dendrites, and axon in your description. How does the structure of a neuron help it carry out its function efficiently?
Answer: A neuron has three main parts: dendrites, an axon, and a cell body or soma , which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells. Dendrites branch as they move towards their tips, just like tree branches do, and they even have leaf-like structures on them called spines.
The axon (tree roots) is the output structure of the neuron; when a neuron wants to talk to another neuron, it sends an electrical message called an action potential throughout the entire axon.
The features of neurons help them to carry out their function efficiently:
they have a long fibre (axon) so they can carry messages up and down the body over long distances
in a stimulated neuron, an electrical nerve impulse passes along the axon
the axon is insulated by a fatty (myelin) sheath - the fatty sheath increases the speed of the nerve impulses along the neuron
at each end of the neuron are tiny branches (dendrons), which branch even further into dendrites - the dendrites receive incoming nerve impulses from other neurons

Explain how warm atmospheric conditions lead to severe storms.
The warm atmospheric conditions lead to severe storms is Thunderstorms
Layers of warm, moist air rise in a strong updraft to cooler areas of the atmosphere, whereupon thunderstorms form. At that location, the updraft's moisture condenses to create imposing cumulonimbus clouds and, eventually, precipitation.
Thunderstorm development requires three basic components: moisture, an unstable atmosphere, and a method to get the atmosphere moving. To create thunderstorm clouds and precipitation, moisture is required.
The warm air cools and condenses as it ascends, generating tiny water droplets. When there is sufficient instability in the atmosphere, warm air rises swiftly, and the water vapor condenses quickly to form cumulonimbus clouds. Usually, it takes less than an hour for these cumulonimbus clouds to form.
