A lasting physical change in the brain as a memory forms is called a

Answers

Answer 1

A lasting physical change in the brain as a memory forms is called a memory trace or an engram. Memory traces are created through a process called synaptic plasticity.


When we experience something new, information flows through our sensory pathways and activates specific patterns of neurons in the brain. The more we repeat or rehearse that experience, the stronger the connections between those neurons become. Over time, this creates a stable and long-lasting memory trace that can be retrieved later on when we need to remember that information.

Memory traces are not located in one specific area of the brain, but rather are distributed across various neural networks. For example, memories related to visual information are stored in the visual cortex, while memories related to language are stored in areas of the brain that are involved in language processing.

Since most of the 100 species did not actually survive when they migrated, this will bodes well for species and species have to leave a habitat when it is destroyed.

The biggest collection of creatures that can generate viable offspring, often through sexual reproduction, from any two individuals of the proper sexes or mating types is referred to as a species in biology. It is a unit of biodiversity as well as the fundamental categorization and taxonomic rank of an organism. A species can also be identified by its karyotype, DNA sequence, appearance, behaviour, or ecological niche. In addition, since fossil reproduction cannot be studied, palaeontologists employ the chronospecies idea.

There are between 8 and 8.7 million different species of eukaryotes, according to the most current accurate estimate. But by 2011, just 14% of these had been described.

The two-part designation "binomial" is given to every species (with the exception of viruses). The genus to which the species belongs is the first component of a binomial. The second component is known as the particular name or the specific epithet (in zoological and botanical nomenclature, respectively). For instance, the Boa constrictor is a member of the genus Boa and is known by the epithet constrictor.

Secondary alcohol
Ketone
Tertiary alcohol

Answers

In general, the possible products of an acid-catalyzed hydration of an alkene include both primary and secondary alcohols. Carboxylic acids and ketones can also be produced, depending on the reaction conditions and the structure of the alkene.

The mechanism of acid-catalyzed hydration involves the addition of water to the carbon-carbon double bond of the alkene, followed by protonation of the intermediate carbocation by the acid catalyst. The resulting carbocation can then react with a water molecule to form an alcohol or with another alkene molecule to form a ketone. The final product depends on factors such as the nature of the acid catalyst, the temperature, and the presence of other functional groups in the alkene molecule. Overall, acid-catalyzed hydration is a useful reaction for synthesizing alcohols and related compounds from simple starting materials.

for an uncharged molecule, the direction of passive transport across a membrane is determined solely by its concentration gradient.

Answers

Yes, that statement is generally correct. In passive transport, substances move across a membrane from an area of higher concentration to an area of lower concentration. This movement occurs because the molecules are in constant motion and will naturally move from an area of higher concentration to an area of lower concentration until equilibrium is reached.

For an uncharged molecule, the direction of passive transport is determined solely by its concentration gradient, which is the difference in concentration of the molecule between two areas. If the concentration of the molecule is higher on one side of the membrane than the other, the molecule will naturally move from the side of higher concentration to the side of lower concentration until equilibrium is reached.

This type of passive transport is often referred to as simple diffusion, and it occurs without the need for energy or any other external factor. However, the rate of diffusion can be affected by several factors, including the size and shape of the molecule, the temperature, and the characteristics of the membrane itself (e.g., its thickness, composition, and permeability to the molecule).

Emissions from power plants that burn fossil fuels increase atmospheric carbon dioxide, which is absorbed by the ocean.

Answers

An anthropogenic activity that can increase ocean acidification is the emissions from power plants that burn fossil fuels.

Anthropogenic activities, or human activities, can contribute to ocean acidification by releasing large amounts of carbon dioxide (CO2) into the atmosphere through the burning of fossil fuels such as coal, oil, and natural gas. This carbon dioxide is then absorbed by the ocean, where it reacts with water to form carbonic acid (H2CO3), which increases the acidity of the ocean water. This decrease in pH, known as ocean acidification, can have detrimental effects on marine ecosystems, including the ability of marine organisms such as corals, shellfish, and plankton to build and maintain their shells or skeletons, as well as disrupt marine food webs and ecosystems.

Functional genomic approaches are favored over biochemical approaches to determine the function of a gene for all these reasons, except "biochemical approaches are more expensive." The correct option is B.

Functional genomic approaches are favored over biochemical approaches to determine the function of a gene for several reasons.

One of the main advantages of functional genomic approaches is that they can bypass the need to isolate individual proteins, which can be time-consuming and technically challenging.

Instead, these approaches use computational methods to identify gene function from DNA sequence alone, allowing for more efficient and high-throughput analysis of gene function.

Another advantage of functional genomic approaches is their accuracy.

By examining the effects of gene expression on cellular processes, these approaches can provide a more comprehensive understanding of gene function than biochemical approaches that focus on the properties of individual proteins.

However, one of the reasons that functional genomic approaches are preferred over biochemical approaches is not that they are more cost-effective.

In fact, functional genomic approaches can be more expensive than biochemical approaches, particularly if they involve the use of high-throughput sequencing technologies or the development of new computational methods.

Nonetheless, the benefits of functional genomic approaches in terms of speed, accuracy, and comprehensiveness often outweigh the increased cost. Therefore, the correct answer is B.

The peripheral nervous system controls involuntary muscle actions, while the autonomic nervous system controls automatic functions such as breathing and heart rate. It consists of the brain and the spinal cord, which together control the entire body’s movement. The central nervous system receives information from the peripheral nervous system (PNS) and processes it before sending signals to the muscles to cause movement. The CNS also sends signals to the autonomic nervous system (ANS), which controls involuntary muscle actions like breathing and heartbeat. The CNS is responsible for interpreting and processing information from the environment and making decisions about how to respond.
