The person with skin cancer will have an abnormal karyotype and abnormal nucleus shape and size during interphase.
This is when organisms coexist by sharing different resources within their habitat.
Answer:
resource partitioning
Explanation:
Resource partitioning is the division of the limited resources to avoid the competition in ecology chain. The organisms are competing to have limited resources, so they need to find a way of coexisting together and not to endanger each other.
This partitioning is good because it shows how species who have the same needs can live together in the same ecological community.

What is the electrical charge of the nucleus of an atom that has 11 protons , 12 neutrons , and 11 electrons ?
Answer:
The 11 positive protons cancel out the 11 negative electrons, and the overall charge of the atom is zero. So it neutral
Explanation:
I hope this helps!!
The nucleus of an atom has only protons and neutrons. Since the neutrons are neutral, the charge on the nucleus, in this case, would be +11.
What is the atomic charge?The difference between the number of electrons and protons in an atom is defined as the charge on that particular atom. An atom has three sub-atomic components. These are electrons, protons and neutrons.
The electrons are negatively charged, the protons are positively charged and the neutrons are neutral.
Because the neutrons are neutral, the increase or decrease in the number of electrons or protons affects the charge on an atom. If the number of protons is higher, the atom will be positively charged. If the number of electrons is higher, the atom will be negatively charged.
The protons and neutrons are present in the nucleus of an atom and the electrons are present in atomic shells.
Therefore, in a nucleus with 11 protons, and 12 neutrons, the charge will be +11

Explanation:
your brain and neurons are in constant action, sending billions of ___________and________messages each day to keep everything, from deep recesses of the brain to the remote wilderness of your toes in touch
halp me ;-;
Answer:
Until recently, most neuroscientists thought we were born with all the neurons we were ever going to have. As children we might produce some new neurons to help build the pathways - called neural circuits - that act as information highways between different areas of the brain. But scientists believed that once a neural circuit was in place, adding any new neurons would disrupt the flow of information and disable the brain’s communication system.
In 1962, scientist Joseph Altman challenged this belief when he saw evidence of neurogenesis (the birth of neurons) in a region of the adult rat brain called the hippocampus. He later reported that newborn neurons migrated from their birthplace in the hippocampus to other parts of the brain. In 1979, another scientist, Michael Kaplan, confirmed Altman’s findings in the rat brain, and in 1983 he found neural precursor cells in the forebrain of an adult monkey.
These discoveries about neurogenesis in the adult brain were surprising to other researchers who didn’t think they could be true in humans. But in the early 1980s, a scientist trying to understand how birds learn to sing suggested that neuroscientists look again at neurogenesis in the adult brain and begin to see how it might make sense. In a series of experiments, Fernando Nottebohm and his research team showed that the numbers of neurons in the forebrains of male canaries dramatically increased during the mating season. This was the same time in which the birds had to learn new songs to attract females.
Why did these bird brains add neurons at such a critical time in learning? Nottebohm believed it was because fresh neurons helped store new song patterns within the neural circuits of the forebrain, the area of the brain that controls complex behaviors. These new neurons made learning possible. If birds made new neurons to help them remember and learn, Nottebohm thought the brains of mammals might too.
Other scientists believed these findings could not apply to mammals, but Elizabeth Gould later found evidence of newborn neurons in a distinct area of the brain in monkeys, and Fred Gage and Peter Eriksson showed that the adult human brain produced new neurons in a similar area.
For some neuroscientists, neurogenesis in the adult brain is still an unproven theory. But others think the evidence offers intriguing possibilities about the role of adult-generated neurons in learning and memory.

Which process begins with the replication of DNA in the nucleus of a cell?
A. cell division
B. energy capture
C. protein synthesis
D.cellular respiration
The process that begins with the replication of DNA in the nucleus of a cell is cell division, which is present in option A, and in the cell division phase, the cell divides to form daughter cells.
What is cell division?Cell division is a process in which the cell first grows in the G1 phase of the cell cycle, then replicates DNA in the S phase, then enters the G2 phase, and finally enters the mitosis or cell division phase. The DNA replication starts in the S phase, and in this phase, the DNA divides to form two DNA strands, so that in the division phase, each daughter cell gets parental DNA.
Hence, the process that begins with the replication of DNA in the nucleus of a cell is cell division, which is present in option A, and in the cell division phase, the cell divides to form daughter cells.

CELLULAR RESPIRATION
What happens to the energy after cellular respiration? What happens to the carbon dioxide and water?
Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP. Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid.

How do scientists plan to use copy number variants and identical twins to determine the roots of diseases? In your response, use the words: gene
Identical genes have the same genetic material and the same genes. So if they both have a disease it's likely that it's genetic.
Scientists plan to use copy number variants (CNVs) and identical twins to determine the genetic differences between them and the cause of genetic disease as CNVs are variations in the copies of a gene in an individual's genome.
What is the significance of copy number variants?Scientists use copy number variants (CNVs) to study the genetic diseases in twins and CNVs are variations in the copies of a gene in an individual's genome, but in identical twins, they have the same genetic makeup. By analyzing the CNVs in twins, scientists can identify the genes that may be involved in the disease and how they contribute to its development.
Hence, scientists plan to use copy number variants (CNVs) and identical twins to determine the genetic differences between them and the cause of genetic disease as CNVs are variations in the copies of a gene in an individual's genome.
