why does the cell membrane being thrown up in many folds along one side?​

Answers

Answer 1
This folding allows a greater amount of membrane to be packed into the mitochondrion.
Answer 2
Answer:

It's not clear what you mean by "the cell membrane being thrown up in many folds along one side". However, one possible explanation for a folded cell membrane is the process of endocytosis.

Endocytosis is a cellular process by which the cell takes in material from the outside environment by engulfing it with a section of the plasma membrane. This section of the membrane then folds inward and forms a small pouch, which eventually pinches off to become a vesicle within the cell. This process can occur in several forms, including phagocytosis, pinocytosis, and receptor-mediated endocytosis.

During endocytosis, the cell membrane is temporarily folded or invaginated to form the vesicle that contains the material being taken in. This can result in the appearance of a folded membrane, as observed under a microscope. Once the vesicle is formed, it can be transported to other parts of the cell for various purposes, such as digestion, recycling, or secretion.

Overall, endocytosis is an important process for maintaining the homeostasis of the cell and is involved in a variety of cellular functions, including nutrient uptake, immune defense, and cell signaling.

What is it called when a foreign gene is inserted into an organism?

Answers

When a foreign gene is inserted into an organism, it is referred to as genetic engineering.

Genetic engineering is the method of modifying the genetic material of an organism, either by direct gene transfer or by selective breeding, to obtain desirable traits or to get a better understanding of the organism's genetics. It entails inserting, deleting, or changing genes in an organism's genetic code.The foreign gene is introduced into the organism by a vector. A vector is a carrier that carries genetic material from one organism to another. Plasmids, bacteriophages, and viral vectors are some of the most common vectors used in genetic engineering.

The foreign gene, for example, is isolated from its original organism and then inserted into a vector, which then carries it into the host organism.The new genetic material is then incorporated into the host organism's DNA. If it is carried out in a gamete, it will be inherited by the organism's progeny, resulting in genetic modification or genetic engineering of the species. The introduced gene might come from a different species, a natural variant of the organism, or a totally artificial construct, such as a gene designed to treat a genetic illness. The technique has a variety of uses, including biotechnology, agriculture, and medicine.

Where are the low-energy electrons located after the electron transport chain is completed?- They are recycled to earlier steps in the process.- They are added to H+ to form H.- They are located in the cytoplasm, where they contribute to the overall negative charge of the cell.- They are located in the bonds of H2O.- They are located in the bonds of ATP after chemiosmosis.

Answers

The low energy electrons after the electron transport chain (ETC) is completed: (4) They are located in the bonds of H₂O.

ETC is a series of electron transporters present in the inner mitochondrial membrane and the thylakoid of chloroplast through which the electrons are transported. This process is coupled with the formation of proton gradient which is used to generate energy components like ATP and NADPH.

The low energy electrons are the same high energy electrons at the beginning of the ETC. After passing through the series of transporters they lose their energy and complete the process by reducing the available oxygen molecule by the formation of water (H₂O).

Therefore the correct answer is option 4.

what do researchers think is one cause of memory impairment related to growing older

Answers

One cause of memory impairment related to growing older, according to researchers is the decline in cognitive processing speed.

As we age, the rate at which we process information gradually slows down, resulting in difficulties with tasks that require us to process information quickly and accurately.

This cognitive slowing is thought to be related to changes in the brain that occur as we age, such as reduced brain volume and reduced connectivity between different regions of the brain. Additionally, factors such as stress, poor sleep, and certain medical conditions can also contribute to memory impairment.

To help maintain memory and cognitive function as we age, it is important to engage in activities that challenge the brain, such as learning new skills, reading, and engaging in social activities.

A healthy lifestyle, including a balanced diet, regular exercise, and good sleep habits, can also help support brain health and reduce the risk of cognitive decline.

Answers

When mating the white feathered trait is dominate while the red feathered is resesive so both parents would have to have red feathers for there offspring to have red feathers.

Dominant refers to the transmission of qualities that are normally carried vertically from parent to kid, where both the parent and the child are impacted by the trait or disorder linked to that gene. The most prevalent form is autosomal dominant, in which the affected person carries both the pathogenic and benign alleles of the linked gene, which is located on one of the 22 non-sex chromosomes. One harmful allele is enough to provide the characteristic in this inheritance pattern. The 50% likelihood of passing on the trait to kids is caused by an affected person having just one of two copies of the pathogenic gene.

Recessive, as it relates to genetics, describes the connection between an observed trait and the two inherited forms of a gene associated with that trait. Each gene has two alleles that an individual receives from each parent. When a trait is recessive, both of the (recessive) alleles of the gene that causes it must be present for the trait to manifest. When there is only one copy of an allele, it does not create any traits at all. In contrast, a dominant trait can only be expressed if one of the two alleles is present.

scientists hypothesize that over millions of years, the y chromosome has lost genes to the x chromosome. during what stages of meiosis might the y chromosome have transferred genes to the x chromosome? explain.

Answers

Scientists hypothesize that over millions of years, the Y chromosome has lost genes to the X chromosome. In meiosis, the X and Y chromosomes pair during the pachytene stage. As a result, DNA recombination occurs.

The non-homologous regions of the X and Y chromosomes are unpaired. As a result, the Y chromosome will act as a substrate for meiotic recombination. As a result, some genes are transferred from the Y chromosome to the X chromosome.

A mutation in the male-determining chromosome (the Y chromosome) will be passed on to subsequent generations without any opportunity for recombination, as males only have one copy of this chromosome.

As a result, the Y chromosome will be more susceptible to mutational deterioration than the X chromosome, which is more frequently recombined in both sexes. This is one of the reasons that the Y chromosome is used to track evolutionary relationships within species.

The X chromosome is also subject to mutation and recombination, but because females have two copies of this chromosome, it is not as susceptible to loss.

Why is an action potential an all-or-none response

Answers

An action potential is an all-or-none response because it is triggered when the membrane potential of a neuron reaches a certain threshold level, at which point an action potential is initiated and propagated down the axon.

The threshold level is a specific voltage that must be reached in order to trigger an action potential. Once the threshold level is reached, the action potential will always be the same size and duration, regardless of the strength of the stimulus that triggered it. In other words, the response of the neuron is "all-or-none" - it either fires an action potential or it does not, and the size and duration of the action potential are constant.

This is because the initiation and propagation of an action potential depend on the opening and closing of ion channels in the neuron's membrane. When the membrane potential reaches the threshold level, voltage-gated ion channels open, allowing positively charged ions (such as sodium) to rapidly flow into the neuron, depolarizing the membrane and initiating an action potential.

Answers

The true nature of natural selection can be best described as "d) heritable traits that promote reproduction become more frequent in a population from one generation to the next.

Through natural selection, traits that promote reproduction become more frequent in a population from one generation to the next. Natural selection is a method that leads to species and organism development by allowing the survival and propagation of organisms with desirable characteristics.

Natural selection is driven by the struggle for existence among organisms in a population, which leads to the death of certain organisms with undesirable characteristics and the growth of organisms with desirable characteristics that enable them to survive and reproduce.

Therefore, correct option is D.

Answers

The goal of antimicrobial susceptibility testing is: option (B) states that "to determine which antimicrobial drug is most effective at inhibition of the causative agent".

This is because antimicrobial susceptibility testing tests the ability of an antimicrobial drug to inhibit or kill a particular type of bacteria or microorganism. It helps determine which drug will work the best to treat an infection.

This is important because it can help doctors choose the most effective drug for the particular infection. It also helps determine the least likely drug to cause allergic reactions, toxicity, or other adverse effects in the patient.

Ultimately, the goal of antimicrobial susceptibility testing is to determine which antimicrobial drug the patient is most sensitive to, so that the most effective treatment can be used.
