Answer:
D
Explanation:
mitosis creates exact copies of the starting cell
In mitosis the two resulting cells are identical to the starting cell and identical to each other. Therefore, option (D) is correct.
What is mitosis?In cell biology, the cell cycle phase known as mitosis is when replicated chromosomes are divided into two new nuclei. Mitosis, the process of cell division, creates genetically identical cells with a constant number of chromosomes. Thus, equational division is another name for mitosis.
Making additional diploid cells is the goal of mitosis. Each chromosome is copied, and the copies are then distributed to the various sides of the cell. In this method, each new cell receives a copy of each chromosome when the cell splits in half.

D. Water vapor
Hope this helps!
Answer:
D water vapors
Explanation:
When scientists examine the gases ejected during a volcanic eruption, the majority of the gas is water vapor. How does the process of subduction provide a water source for volcanic gases?
Answer: Volcanic gases are gases given off by active (or, at times, by dormant) volcanoes. These include gases trapped in cavities (vesicles) in volcanic rocks, dissolved or dissociated gases in magma and lava, or gases emanating from lava, from volcanic craters or vents.
Answer:
When an oceanic crust and a continental crust converge, the denser oceanic crust subducts under the continental crust. During this process, seawater is added to the volcano’s magma. Much of this water is heated and ejected during an eruption as water vapor.

Kidney waste from sweating is not true of the excretory system.
The correct answer is option B.
What does the excretory system do?The principal function of the urinary system is to maintain the volume and composition of body fluids within normal limits. One aspect of this function is to rid the body of waste products that accumulate as a result of cellular metabolism, and, because of this, it is sometimes referred to as the excretory system.
What are the parts of the excretory system and their functions?The primary excretory organs in the human body are the kidneys, ureters, and urinary bladder, involved with the creation and expulsion of urine. Through these organs, much of the nitrogenous waste of the body, especially urea, is expelled.

B. A type of mutation involving chromosomes
C. An environmental agent that changes DNA
D. A mutation that is inherited from parents
The answer to the question is that Mutagen is an environmental agent that changes DNA.
Types of Mutagens:
Physical mutagens: Ionising radiation, such as X-rays, gamma rays, and alpha particles, is one example. UV radiations can also act as possible mutagens.Chemical mutagens: Mutagens include arsenic, nickel, and chromium. Some organic chemicals, such as benzene, are also mutagenic in nature.Biological mutagens: Transposonas and viruses are two examples of biological mutagens. Furthermore, some bacteria, such as Helicobacter pylori, have been linked to an increased risk of stomach cancer.Thus we can conclude that A mutagen is a physical or chemical substance that permanently alters genetic material in an organism, generally DNA, increasing the incidence of mutations over the natural background level.

How can we stop the amount of emissions that contribute to greenhouse gases?
Which part of the brain keeps you from losing your balance when you are standing on a skateboard?
Transformation is a process in which bacteria take up new DNA released by dead cells and integrate it into their own genomes (see Chapter 9). In Streptococcus pneumoniae (which causes many cases of pneumonia, inner-ear infections, and meningitis), the ability to carry out transformation requires from 105 to 124 genes, collectively termed the com regulon. The com regulon is activated in response to a protein called competence-stimulating peptide (CSP), which is produced by the bacteria and exported into the surrounding medium. When enough CSP accumulates, it attaches to a receptor on the bacterial cell membrane, which then activates a regulator protein that stimulates the transcription of genes within the com regulon and sets in motion a series of reactions that ultimately result in transformation. Does the com regulon in S. pneumoniae exhibit positive or negative control
Answer:
Positive (inducible)
Explanation:
Increased levels of CSP induce the receptor to stimulate transcriptional activator functions, which allow gene expression to occur similar to what happens in positive inducible.

Patient 1 has Type ___ blood.
Answer:
A.
Explanation:
Patient 1 has Type A blood because agglutination occurs due to reaction with anti-B. We know that A blood group has antigen A and it is anti-B means that they attack on B type of blood cells while on the other hand, B blood group has antigen B and it is anti-A means that they will attack on the A type blood cells upon mixing. So according to the chart, there is nothing happens by reaction of the blood with anti-A whereas agglutination occur by reaction with anti-B so we can say that the patient has type A blood.

C. Ecosystems are complex, interactive systems that include both biotic and abiotic components of the environment. D. All of these are true statements.
Answer:
All the statements are true and the correct option is;
D. All of these are true
Explanation:
Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities
An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system
An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity
Therefore all the statements are true.

In 100 words or more, explain the role natural selection plays in causing biological resistance.
Plz help
Answer:
The ability of a microorganism to tolerate the effects of an antibiotic is known as antibiotic resistance. It's a certain kind of drug resistance. Antibiotic resistance develops naturally through random mutation, but it can also be engineered by putting a population under evolutionary stress. Bacteria will then transmit genetic information in a hominid-like manner once such a gene has been formed. Following the development of such a gene, bacteria may use plasmid exchange to transfer genetic information horizontally (between individuals). Multiresistant bacteria, also known as superbugs, carry several resistance genes. the reasons for it Transformation protocols can also be used to incorporate antibiotic resistance into a microorganism. This may be a good way to get artificial genes into a microorganism. Antibiotic tolerance is a product of natural selection in evolution. Antibiotic activity is a type of environmental pressure; bacteria that have developed a mutation that allows them to survive will continue to replicate. They will then pass this trait on to their children, resulting in a generation that is completely immune.

Finn listed two of the three steps involved in gene therapy. 1. The normal allele is removed from the chromosome. 2. The normal allele is added to the cells of a person with the disorder. Which step should he also include, and where?
Answer:
The unhealthy gene sequence is cut from the DNA before 2
Explanation:
Gene therapy refers to genetic engineering techniques aimed at introducing exogenous nucleic acids (either DNA or RNA) into the patient's cells in order to restore gene function. Gene therapy techniques hold a great promise to treat genetic diseases and disorders. Gene therapy may involve replacing defective genes with a functional copy of the gene of interest within the desired cells. For this purpose, it is required to use a DNA-specific damaging agent to knock out the defective gene and subsequently restore normal gene function by inserting a functional gene sequence into the recipient cells. Gene therapy techniques can be divided regarding target cells into 1-somatic gene therapy, where genetic modifications are applied on somatic body cells (and therefore they are not inherited by offspring), and 2-germinal gene therapy, where genetic modifications are applied on germinal cells (i.e., gametes) or undifferentiated stem cells (and therefore genetic changes may pass to the following generations).
