Igenous rocks are created by lava colling and cristalization. They can be either intrusive (slow cooling) or extrusive (fast cooling). The option that includes all ingeous rocks is D). created by lava.
What is an igneous rock?Igenous rocks come straight from the interior of the Earth.
A liquid mass of silicate composition coming from the Earth's core erupts out of a volcano as lava.
Since this melted mass comes from the Earth's interior, its temperature is extremely high.
Lava begins to cool and solidify during its ascent to the Earth's surface.
Igneous rocks are produced by the magma cooling and cristalizing when they get in touch with air.
Thre are two types of igneous rocks
• plutonic rocks ⇒ close to the terrestrial crust ⇒ intrusive ⇒ slow cooling
• volcanic rocks ⇒ on the surface ⇒ extrusive ⇒ quick cooling
Among the options, there are three descriptions that match the igneous rocks,
cooled quickly ⇒ this is the case of extrusive rocks, when lava gets in contact with cold air and quickly cristalizes.intrusive origin ⇒ this is the case of magma that slowly cristalizes near the crustcreated by lava ⇒ this is the case of all igneous rocks.If we need to find only one of these options, we could choose option D, created by lava, since it involves all types of ingeous rocks.

Hormone released by the duodenum in response to acids and lipids in the duodenum.
Cholecystokinin is perspired by cells of the upper little intestine. Its secretion is stimulated by the introduction of hydrochloric acid, amino acids, or fatty acids into the stomach or duodenum.
What is Cholecystokinin?Cholecystokinin is a hormone produced in your little intestine. It recreates a fundamental role in digestive function. When fats and proteins enter your small intestine, cholecystokinin activates your gallbladder and pancreas to contract.The most recognized positions of this hormone are in digestion and appetite. It improves digestion by delaying the emptying of food from the stomach and promoting the production of bile in the liver as well as its departure from the gall bladder.CCK peptides stimulate pancreatic enzyme secretion and growth, gallbladder compaction, gut motility, and satiety, and deter acid secretion from the stomach.

The __________ is the visible aspect of characteristics passed from parent to offspring
The traits is the visible aspect of characteristics passed from parent to offspring.
Through the process of heredity, organisms inherit traits from their parents. Traits are the name for these features. Every person is distinct because they each possess a special set of characteristics. Inherited qualities are those that a parent passes on to its offspring during the fertilization process. The way the genetic features are interpreted is what causes the distinction between heredity and inheritance. The term "heredity" refers to the genetic traits that parents pass on to their children; it is frequently referred to as "genetics."Through their genes, parents transmit features or qualities to their offspring, such as eye color and blood type.

Both adult and embryonic stem cells have the potential to be used for medical treatment. Evaluate the potential use of adult and embryonic stem cells as medical treatments. You must contain a justified conclusion
Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.Research carried out with the use of these cells has demonstrated their effectiveness in the treatment of various diseases, such as leukemia, heart disease and hematological diseases. Embryonic stem cells, in turn, have the ability to form any tissue in the body.
How are embryonic stem cells used?Stem cells have the ability to differentiate and self-renew. For this reason, they can be used in the treatment of degenerative diseases. Stem cells stand out for their ability to transform into different cell types, that is, they are cells with a great capacity for differentiation.

The alternative pathway of complement cascade activation begins with ________ binding to the surface of a microbe. c5b c5a c3b c1 factor b
The correct answer is c3b.
The intrinsic C3 thioester bond of the alternative pathway (AP) is progressively hydrolyzed spontaneously by diverse proteins, lipids, and carbohydrate structures on microbes and other external surfaces [12–14], and this further activates the AP [1, 15]. A blue line pointing to C3 denotes the fluid-phase C3b promoting assembly of AP C3 convertase as the proposed mechanism for the reaction of properdin with a target on the foreign surface [27]. Thick red lines signify amplification mechanisms: Factor H regulates and inhibits the tick-over reaction, a gradual spontaneous activation involving C3(H2O) reacting with factor B.

What are activated carriers?A small molecule that has a chemical group attached to it through a high-energy linkage and can donate energy or the chemical group in a variety of chemical processes.
How these activated carriers are produced in Kreb's cycle?The inner mitochondrial membrane's electron-transport chain receives high-energy electron contributions from NADH and FADH2. The activated nucleoside triphosphate GTP, which is closely similar to ATP, is also produced by the citric acid cycle.Electrons from the combustion of carbs, lipids, and other nutrients during glycolysis and the citric acid cycle are used to power the flow of ATP production. These "high-energy" electrons are produced by activated carriers produced during these two types of catabolic events, with the citric acid cycle operating in the mitochondrial matrix producing the majority of these activated carriers. The oxidation of molecules taken from food is finished by the citric acid cycle.

Research in neuroeconomics has linked activity in the nucleus accumbens and ventromedial prefrontal cortex with a reflexive decision system and activity in the medial temporal cortex and lateral prefrontal cortex with reflective decision system.
The nucleus accumbens is considered as the neural interface between motivation and action, playing a key role on feeding, sexual, reward, stress-related, drug self-administration behaviors, etc. The nucleus accumbens is made up of an 'electrophysiological coincidence detector' or shell serially connected to a 'motor sequencer' or core, both supporting the role of the nucleus accumbens as a limbic-motor interface.
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain. It is an integrative hub for emotional, sensory, social, memory, and self-related information processing. Situated in the medial portion of the prefrontal cortex, the highly interconnected vmPFC serves as a region for binding together the large-scale networks that subserve emotional processing, decision-making, memory, self-perception, and social cognition in general.
The medial temporal lobe includes a system of anatomically related structures that are essential for declarative memory (conscious memory for facts and events). The system consists of the hippocampal region (CA fields, dentate gyrus, and subicular complex) and the adjacent perirhinal, entorhinal, and parahippocampal cortices.

Studies on identical twins have found that differences in genes explain 50% of the variability in personality traits.
According to twin studies on personality, genetic influences account for around half of personality variation, with environmental factors causing individuals from the same family to have different personalities accounting for the remaining half. However, these conclusions are supported by quantitative models of human individual differences that calculate genetic and environmental contributions as constants across entire populations.
According to genetic studies, there are 5.2 genetic mutations that separate identical twins on average. Although the same set of genes are used to create identical twins, human development is not entirely genetic. Another factor is the surroundings.
