An object becomes charged when the atoms in the object gain or lose
Answer:
Both
Explanation:
An uncharged object can become charged by gaining or losing electrons.
If an object loses electrons, it is left with more protons, which gives it an overall positive charge.
If an object gains electrons, it will have an overall negative charge.
The build-up of charges on an object is called static electricity.

A pseudogene is a Group of answer choices second copy of a gene that functions when the original copy becomes damaged. gene that is unrelated in sequence to another gene but has the same function. gene that evolved by gene duplication and the acquisition of mutations to yield a gene product that has a slightly different function from that of the original gene product. gene that arose through gene duplication, but by acquiring mutations became nonfunctional.
Answer: Gene that arose through gene duplication, but by acquiring mutations became nonfunctional.
Explanation:
A gene is a functional unit of heredity formed by DNA. They possess a sequence of nitrogenous bases that during translation is read by ribosomes to produce molecules called proteins. A pseudogene is a DNA sequence that resembles a gene, but which has been inactivated in the course of evolution by mutations in its sequence. Thus, it is a gene that derives from other known genes and whose functions are different, may have lost their functionality or have radically changed it. To this day, it is not known exactly how pseudogenes are created, however some theories are as follows:
1. A gene duplication can generate two copies of a gene when only one is needed. A mutation would then occur that deactivates one of the copies. In addition, the duplication event may not be complete, so that the copy has incomplete promoters.
2. They may be fragments of the messenger RNA transcript of a gene may be spontaneously reverse transcribed and inserted into the chromosomal DNA. They lack the promoters of normal genes, so they are not expressed normally.
3. A gene may become non-functional or inactivated if such a mutation becomes fixed in the population. This can occur by normal means such as natural selection or genetic drift.
Hardwired characteristics of the brain that attempt to keep us in balance by correcting deficiencies are referred to as:
Hardwired characteristics of the brain that attempt to keep us in balance by correcting deficiencies are referred to as homeostatic mechanisms.
Homeostasis is the body's ability to maintain a stable internal environment despite external changes.
In the context of the brain, homeostatic mechanisms involve various processes that regulate physiological functions and maintain optimal levels of essential substances.
These mechanisms can include feedback loops that detect imbalances and initiate corrective actions.
For example, if there is a deficiency in a particular nutrient or hormone, the brain may activate mechanisms to increase its production, decrease its consumption, or enhance its absorption from the environment.
Homeostatic mechanisms play a crucial role in ensuring the body's overall stability and functioning, helping to maintain proper levels of various substances and promoting overall well-being.

which is not a way that ancient people classified plants and animals
One way that ancient people did not use to classify plants and animals is based on their genetic or evolutionary relationships.
Ancient classifications of plants and animals were typically based on observable characteristics such as appearance, behavior, and usefulness. They relied on morphological features like shape, size, color, and habitat to group organisms together.
Ancient classifications often focused on practical aspects such as medicinal uses, edible properties, or cultural significance. For example, plants might have been classified based on their healing properties or their suitability for food or construction materials. Animals might have been categorized based on their physical traits, such as their ability to fly or swim.
However, ancient people did not have access to the scientific understanding of genetics or the tools to study DNA sequences, which are fundamental in modern taxonomy. They lacked the knowledge of shared ancestry and evolutionary relationships that form the basis of modern classification systems such as cladistics and phylogenetics.
Therefore, the genetic or evolutionary relationships between organisms were not considered in ancient classifications, distinguishing them from the approach used in modern biological taxonomy.

one day after a biology class four of your friends argue about the difference between phylogeny and systematics. which friend is right? multiple choice friend a states that systematics and phylogenies are really the same, one is more recent than the other, but basically they are the same. friend c argues that systematics is the actual collecting and cataloguing of specimens into museums that can be used later by scientists to construct clades and phylogenies. friend d says that the way she remembers is that systematics is the reconstruction and study of phylogenies. friend b says that systematics is the same as cladistics and cladistics is reconstructing clades, which ultimately lead to the development of phylogenies.
The correct option(A). Friend A states that systematics and phylogenies are actually something very similar, one is later than the other, but fundamentally they are something very similar.
Recognize phylogeny and systematics. Phylogeny - > The transformative history of animal categories or gathering of related species. Systematics - > The investigation of natural variation in an ecological setting, enveloping scientific categorization and including the reproduction of phylogenetic history.
Significance. Phylogeny relates to the transformative history of a scientific categorization of organic entities and it is utilized as a premise in phylogenetics as the last option manages the connections of an organic entity to different organic entities as per developmental similitudes and contrasts.

How does osmosis of water occur across the cell membrane?Plz help I need it ASAP
Answer:
In osmosis, molecules cross the cell's plasma membrane to achieve equilibrium.
Explanation:
A bilipid layer called a plasma membrane typically surrounds cells. Here, lipid molecules are arranged tail-to-tail, with their heads facing outwards. The heads of the lipids, are water soluble, while the tails are insoluble. Proteins and cholesterol also help maintain membrane fluidity.
With the use of its transport proteins, pores and gated channels, embedded among the lipids the membrane maintains its concentration of substances through selective permeability.
Simple diffusion occurs in cells through plasma membranes as a means of passive transport. In osmosis, molecules of water move across the membrane, down their concentration gradient- i.e. they try to balance their concentration or number of water particles.
The water particles move from regions of high concentration to regions of low water concentration. Typically these 'destinations' or regions have large amounts of solute which contributes to the formation of this gradient.
