The Combined DNA Index System (CODIS) is the United States national DNA database created and maintained by the Federal Bureau of Investigation. CODIS consists of three levels of information; Local DNA Index Systems (LDIS) where DNA profiles originate, State DNA Index Systems (SDIS) which allows for laboratories within states to share information, and the National DNA Index System (NDIS) which allows states to compare DNA information with one another.
Answer:
CODIS stands for Combined DNA Index Systems and is a computer program that stores the DNA Fingerprint of convicted criminals and missing persons. This program is very useful in forensic science.
Explanation:
CODIS is a computer program maintained by the FBI, which operates databases across the country. These databases contain more than five million profiles. CODIS covers several different indices.
CODIS uses algorithms to compare 13 different locations in STRs, plus one that determines the gender of the person in question. The system has rules and safeguards to protect the privacy of people in the database. Algorithms that point to positive results - which must be confirmed by an analyst - can provide clues to the police or even identify a possible criminal. The downside of using CODIS is that it only covers the profiles it includes - and there are over a million profiles waiting to be included in the system.

the kidney is an organ that collects wastes and excess water from the blood and sends them to the bladder where they are stored before being removed from the body. which two systems work together to perform this function?
1) immune and respiratory
2) circulatory and excretory
3) skeletal and nervous
4) digestive and circulatory
The two systems that work together to filter blood, remove waste and excess water, and maintain electrolyte balance are the circulatory system and the excretory system. The circulatory system transports blood to the kidneys, where it is filtered, and wastes are excreted as urine by the excretory system.
Explanation:You're correct to identify the kidneys as playing a critical role in waste removal and water regulation. The role of the kidneys is to filter blood, produce urine, and assist in maintaining water and electrolyte balance. The two systems that work together to perform these functions, based on your provided options, are the circulatory system and the excretory system.
The circulatory system is responsible for transporting blood containing metabolic wastes from cells to the kidneys. In the kidneys, more than a million tiny units called nephrons filter this blood. This filtration involves the removal of wastes and the formation of urine. The reabsorption of water, required ions, and useful compounds back into the capillaries that surround the tubules leaves the wastes behind, and this urine is subsequently collected in the bladder. So, the circulatory system and the kidneys (part of the excretory system) work collectively to filter blood, expel wastes, and maintain water and electrolyte balance.
The excretory system includes the kidneys, ureters, urinary bladder, and urethra, and it's responsible for the removal of waste from the body. The kidneys, as part of this system, ensure that undesirable substances and excess water are excreted from the body in the form of urine, which is stored in the bladder before being eliminated from the body through the urethra.

The circulatory and excretory systems collaborate to help the body expel wastes and maintain water-salt balance. The circulatory system carries nutrient-rich blood to the kidneys, the blood is filtered, and essential substances are reabsorbed back into the bloodstream. The excretory system, specifically the kidneys, separates waste and concentrates it into urine for eventual excretion from the body.
Explanation:The two systems that work together to perform the function of collecting wastes and excess water from the blood and sending them to the bladder are the circulatory and excretory systems. The excretory system, particularly the kidneys, ureters, urinary bladder, and urethra, serve to remove metabolic wastes from the body and maintain water-salt balance through processes of filtration, reabsorption, and secretion carried out by the nephrons.
The circulatory system, on the other hand, delivers nutrient-rich blood to the kidneys, where waste products, excess water, and ions are filtered out and sent into the tubule system of the nephron. Healthy substances are reabsorbed back into the bloodstream, whereas body wastes are separated and concentrated into urine, which is then collected in the bladder for eventual excretion from the body through the urethra.

What is the general process scientists use to gather information and answer questions
Answer:
Scientists use a general process known as Scientific Inquiry to ask and answer questions about nature.
Explanation:
Scientific inquiry is best defined as a fixed process that follows the steps of question, hypothesis, and investigation, gathering evidence, and communicating results.
This process is the most widely used process by scientists around the world. It involves investing a given subject in a logical way to find evidence that supports the answer.
It is based on measurable evidence to specify the reasoning.
The general process that scientists use to gather information and answer questions is called the scientific method.
The scientific process begins with making observations or noticing something interesting or unusual about the natural world. Observations can be made through direct observation, measurements, or experiments.
Based on the observations made, scientists formulate a specific and testable question, often referred to as a research question or hypothesis. The question should be clear and focused, guiding the subsequent steps of the scientific method.
A hypothesis is a tentative explanation or prediction for the observed phenomenon. It is an educated guess that can be tested through experimentation or further observation. The hypothesis should be specific and falsifiable, meaning it can be proven wrong through evidence.

Which example best illustrates a method to show differences among Earth’s layers? Carson models how the continental crust varies in thickness.
Marisol records atmospheric and oceanic temperatures at several beaches.
Eliza analyzes seismic wave activity from an earthquake using a computer model. Oscar determines the mineral content of rock core samples at different depths in Earth’s crust.
The correct option is Oscar determines the mineral content of rock core samples at different depths in Earth’s crust
Explanation:We know that Earth layers are divided into different distances from its core. They vary from depth to depth inside the earths core. The layers of earth are basically formed by the types of rocks inside it. The very internal shape of earth contains molten rocks and the very outer layer called the crust has hard rocks so we can say that the types of rocks is responsible for the formation of earth's layers.
The Earth is made up of several layers, which are situated at different depths from the core. The method to show differences among Earth's layers is:
Oscar determines the mineral content of rock core samples at different depths in Earth’s layers.
The Earth is made up of several layers, namely, crust, core, and mantle. These layers are situated at different depths and exhibit different properties. The layers are generally distinguished based on the composition of rock materials and their depth from the core. For instance, the crust of the Earth is hard, whereas the internal layers consist of molten rocks. Thus, different types of rocks shape the Earth layers.
Reasons for incorrect answers:
Continental crust is made up of different types of rocks. However, Earth is composed of crust, mantle, and core. The different temperatures shape the properties of rocks at different layers. Although, the Marisol method cannot be used to show differences in Earth's layers. Eliza analyses seismic wave activity using a computer model. The seismic activity of different layers exhibits different properties. The waves do not determine the differences in Earth's layers.Therefore, the Oscar method determining the mineral content of rock core samples at different depths can show differences in the Earth's layers.

What is chromosomes
A chromosome is a Deoxyribonucleic acid molecule with part or all of the genetic material of an organism.
Answer:
Chromosome is the compact form of genetic material(DNA) present in the nucleus of a cell. These chromosomes are a combination of proteins and DNA. These chromosomes carry our hereditary material in the form of genes.
Each chromosomes carry many genes which are transferred to the next generation. Each chromosome divides into the S- phase and they become compact during the mitosis phase.
Chromosomes can be seen under the microscope in the metaphase stage of cell cycle. 23 pairs of chromosomes are present in each cell out of which 22 are autosomes and 23rd is the sex chromosome.
These sex chromosomes is different in both male and female because females have two X chromosomes and male have one X and one Y chromosome as sex chromosome.

Given the following phylogenetic tree, which two classes of arthropods are the least related?
5dtugyftdset45yultyfdjke5ruyf,k56ltiy
To determine which two classes of arthropods are the least related, one must consult a phylogenetic tree. Without it, we infer from general arthropod taxonomy that classes from distant subphyla, like Hexapoda (insects) and Chelicerata (spiders), would be the least related.
To answer which two classes of arthropods are the least related, it's essential to refer to a phylogenetic tree illustrating the taxonomic relationships among various arthropod groups. In the absence of a specific phylogenetic tree provided for the question, we use general knowledge of arthropod taxonomy to infer relationships. Phylum Arthropoda is divided into subphyla such as Hexapoda (insects and relatives), Myriapoda (millipedes, centipedes, and relatives), Crustacea (crabs, lobsters, crayfish, isopods, barnacles, and some zooplankton), and Chelicerata (horseshoe crabs, arachnids, scorpions, and daddy longlegs).
The two classes of arthropods that would be least related according to this classification are likely to come from distant subphyla, for example, an insect from Hexapoda and a spider from Chelicerata. However, without a specific phylogenetic tree, it is not possible to determine exactly which two classes are the least related, and this answer would only be inferred from the broader taxonomic categories.
_______ are found in BOTH viruses AND in living single-celled organisms, such as protozoans and bacteria.
You could say DNA and RNA but I would use DNA to be more specific
Answer:
DNA and RNA
Explanation:
Nucleic acids (DNA and RNA) are found in both viruses and in living single-celled organisms, such as protozoa and bacteria. They are responsible for heredity and are the basis for building proteins that are essential to the body.
Both are made up of subunits - the nucleotides. Each nucleotide is formed by a 5-carbon sugar (deoxyribose, in DNA and ribose in RNA), a radical of phosphoric acid (phosphate) and a cyclic compound with nitrogen (the nitrogenous base). There are five types of nitrogenous bases: adenine (A), guanine (G), cytosine (C), thymine (T) and uracil (U). These molecules are responsible for the formation of genes.

Carbon dioxide (CO2) combines with a five-carbon compoundIn one to three sentences, describe what happens during the reduction stage of the Calvin cycle.
We are well aware that there are two stages of photosynthesis:
Light dependent reactions Light independent reactions/ Calvin cycle/ dark reactions.Calvin cycle or light-independent reactions:
This comprise the process during which carbon dioxide enters into the leaves of plants and passes through series of steps to form sugar or food. This process depends on the supply of ATP, (the ATP that is formed previously during light dependent reactions).
Now there are three stages of Calvin cycle:
1) carbon fixation 2) reduction 3) regenerationDuring the process of carbon fixation CO2 combines with a 5-carbon compound called RuBP or ribulose-1,5-bisphosphate which results in the synthesis of a 6-carbon compound that splits up in to 2 three carbon compounds called phosphoglyceric acid (3-PGA).
Here out focus will be the process of Reduction.
Reduction is the second stage of Calvin cycle during which phosphoglyceric acid (3-PGA) is converted to glyceraldehyde-3-phosphate (G3P) that is a sugar. During the process of reduction, energy in the form of ATP and NADPH are used for the conversion of 3-PGA to G3P. As 3-PGA is reduced to G3P, therefore this process is known as reduction.
After reduction, a series of reactions occur that lead to the synthesis of glucose but since focus of our question was reduction, so you can see more details of the process in attached figure.

What must occur before cell division
The process when cell divides is refereed to as mitosis.when a cell has copied all its DNA then the cell normally divides.
Before the mitosis occurs the cell has to replicate its DNA making a copy of each chromosome this phase is referred to as inter-phase while the cell division is referred to as mitosis
SUMMARY
A cell has to replicate its DNA making a copy of each chromosome,called sister chromatids
Before cell division occurs, a cell goes through stages of the cell cycle which are the G1 phase (growth and carrying out functions), the S phase (DNA replication), and the G2 phase (further growth and preparation for division). These stages are crucial to ensure that each resulting cell after division has a complete set of genetic material.
Explanation:Before cell division can occur, a cell must pass through several stages. Collectively, these stages are referred to as the cell cycle. The first stage is the G1 phase, where the cell grows and carries out its functions. Next is the S phase, during which DNA replication occurs. Here, the cell makes a copy of its genetic material in preparation for division. This is followed by the G2 phase, where the cell continues to grow and prepares for division. Lastly, the cell enters the M phase, where cell division, specifically mitosis, actually occurs.
The processes that occur before cell division, particularly DNA replication, are crucial because they ensure that each daughter cell will have a complete set of genetic material after the cell divides.
