In seizure disorders, electrical activity in the brain is periodically interrupted, resulting in some temporary impairment of brain function.
What in the brain causes seizures?Nerve cells (neurons) in the brain generate, send, and receive electrical impulses that allow nerve cells in the brain to communicate. Anything that interferes with these communication paths can lead to seizures. Genetic mutations may be the cause of some types of seizure disorders.In seizure disorder, the brain's electrical rhythms tend to become unbalanced, leading to recurrent seizures. In patients with seizures, normal electrical patterns are disrupted by sudden, synchronized bursts of electrical energy that can temporarily impair consciousness, movement, or sensation.Which parts of the brain are affected during a seizure?The temporal lobe is the area of the brain most likely to lead to seizures. The mesial (middle) portions of both temporal lobes are of great importance in epilepsy. It often causes seizures and is susceptible to damage and scarring.

A reptile lives on both land and water, unlike a fish, which only exists in water. A fish is a type of cold-blooded or ectothermic aquatic vertebrate. The reptile, which has scales or scutes covering it, is a cold-blooded creature as well. Scales are a feature of fish, though cartilaginous fish lack them.

Microaerophiles are group of microbes must have oxygen to grow .
Microaerophiles are those microbes, that require oxygen for growth, are unable to grow at normal atmospheric oxygen tensions, they also adopt particular environment with low oxygen tension .
Microaerophiles need oxygen because they cannot ferment or respire anaerobically. They Produce ATP via aerobic respiration or fermentation. Microaerophiles gets poisoned by high concentrations of oxygen. for example Lactic acid bacteria (LAB) are well defined as a group of microaerophilic.

which antibody isotype to antigen can inhibit naive b lymphocyte activation of pre existing (already present)?
IgG antibody isotype to antigen can inhibit naive b lymphocyte activation of pre existing (already present).
What is Antibody ?Proteins called antibodies defend you when your body comes into contact with an unwelcome chemical. Antibodies, which are made by your plasma, bind to these foreign substances and drive them out of your body.
Immunoglobulin is another name for an antibody.
Antigens have molecules on their surfaces that are different from those your body naturally produces. Therefore, as soon as an antigen enters your body, your immune system immediately recognises it. Your immune system requests antibody defence in order to combat this antigen invader.
The B cell produces antibodies (specialized white blood cells). A B cell multiplies and clones when it comes into touch with an antigen. These plasma cells, also known as cloned B cells, unleash countless amounts of antibodies into your lymphatic and blood systems.
Your body has antibodies in a number of places, including your skin, lungs, tears, saliva, and even breast milk. In actuality, colostrum contains significant amounts of antibodies. Because of this, breast- or chest-feeding can strengthen your baby's immune system.

two competing theories about the source of oxygen in photosynthesis were tested in the 1940s-50s using radioactive isotopes. about what did the theories disagree?
Theories that were obtained while doing research using radioactive isotopes disagree as to whether the [tex]O_{2}[/tex] produced during photosynthesis came from [tex]CO_{2}[/tex] (carbon dioxide) or [tex]H_{2}O[/tex] (water).
Most scientists believed that plants produced [tex]O_{2}[/tex] by removing it from [tex]CO_{2}[/tex] in the 1800s. In the 1950s, researchers tested this theory by tracking the fate of oxygen atoms during photosynthesis using the heavy oxygen isotope [tex]^{18}O[/tex].
There was two experiments:
1. A plant exposed to [tex]^{18}O[/tex]-containing carbon dioxide produced no labeled oxygen gas ([tex]^{18}O[/tex] containing).
2. A plant given [tex]^{18}O[/tex] water produced tagged [tex]O_{2}[/tex].
These investigations demonstrated that the [tex]O_{2}[/tex] produced during photosynthesis is derived from [tex]H_{2}O[/tex] rather than [tex]CO_{2}[/tex].

These crosses could result in genotypes with homozygous dominant, homozygous recessive, or heterozygous genes.
What is the genotype of this cross's progeny?The genetic makeup of the sex cells or gametes (ova and sperm) that were combined during conception to create an offspring determines its genotype. Each parent contributed one sex cell. Normal sex cells only have one copy of each gene for each characteristic.
How can the genotype of a test cross be determined?By examining the phenotypes of the offspring, the unknown genotype can be identified. If mating the unknown recessive phenotypic individual with the unknown dominant phenotype (PP or Pp genotype) results in solely dominant phenotypes (no recessive), then the unknown individual is homozygous dominant.

This outer covering is formed during a process called budding off and the outer covering comes from the infected host cell. Newly created virus cells get enveloped in an outer coat, made of small piece of plasma membrane of cell during the budding process.
The vial genome is released inside host cell due to uncoating of the viral cell. During Uncoating, the capsid gets removed, thereby releasing the viral genome into host cells, after which gene replication and transcription takes place.

By attaching to receptors on target cells, hormones differs cellular functions. A target cell's number of receptors may rise or fall in response to hormone action. Through intracellular or plasma membrane hormone receptors, hormones can directly or indirectly impact cells. A receptor can respond when a hormone or many hormones are present, which starts a cascade of signaling.
The hormone receptor interacts with several molecules to cause a range of changes, including an up-or down-regulation of nutrition sources, growth, and other metabolic processes. The steroid hormones activate cell signaling pathways that control certain genes in the DNA of the cell.

Palaeoanthropology is the scientific study of human evolution
Human evolution is the lengthy process of change by which people originated from apelike ancestors
It can occur by natural selection, when certain traits created by genetic mutations help an organism survive/reproduce. These mutations will pass onto next generation.
On our recent study of DNA, we can see evidence that natural selection has recently made changes, so evolution will never stop.
There are several signs of human evolution-
1. The adaptation to the threat of infectious diseases and High prevalence of diseases like sickle cell disease and thalassemias
2. Also. deviations from expected allele frequencies provide clues that genes have undergone selection.

The expected scenario would be that only male silk moths would be attracted to the paper.
The female silkworm moth releases the pheromone bombykol to draw males to her. Additionally, the wild silk moth, Bombyx mandarina, uses it as its sex pheromone. When this pheromone is spread on to the paper, only male silk moths would get attracted to it to find their mates.
