Answer: model 3 answer, choice C
Explanation: A compound is a mix of two or more elements so then your answer is narrowed down to C and D. And now you have to see which one correctly identifies the definition of a compound. So now you have to see which one correctly identifies the definition of a compound. So your answer is model 3.
How do mutations affect natural selection
Answer:
The idea of natural selection would in theory be affected by mutations because natural selection invloves a species/animal only surviving by having a certain trait. Over time, all of the animals/species would have this trait through elimination partnered with reproduction. A mutation may begin this cycle by giving an animal the ability to have an advantage over its fellow species.

List the process(es) you see in the model that take carbon dioxide OUT of the atmosphere.
Help:)
Answer:
D
Explanation:
The only process in the model that takes carbon dioxide out of the atmosphere is process D.
Process D is otherwise known as photosynthesis and it is peculiar only to green plants and blue-green algae.
During this process, the atmospheric carbon dioxide combines with another inorganic substance (water) in the presence of sunlight energy to produce carbohydrates (glucose). Oxygen is released as the by-product of the process and the equation is as below:
[tex]6CO_2 + 6H_2O + sunlight --> C_6H_1_2O_6 + 6O_2[/tex]

when equipment malfunctions, a(n) _____ needs to be initiated.
A) notification
B) paperwork
C) alarm
D) work order
Answer: Alarm
Explanation:
When equipment malfunction, the reason could be either from the person operating the equipment or there might be some error in the equipment.
As, soon as the equipment malfunctions, there should be an alarm initiated so that to vacant the place as there can be some accident associated with it.
In order to prevent the injury or any causality from taking place, there must be an alarm which is initiated.
Further, the proper paperwork and investigations can be done in order to study the whole case.
3 marks) Compare the ingredients in D5NS to plasma in real blood. List 3 ingredients that are present in real blood plasma that are not present in D5NS.
Answer: The D5NS is a fluid used for maintaining the blood glucose level whereas plasma is a liquid matrix in which red blood cells, platelets, and white blood cells are suspended.
Explanation:
The D5NS is a solution of 5% of dextrose in the normal saline in addition it also contains saline 0.9% NaCl. It is used for intravenous glucose treatment. It is used for patients that have low blood glucose level and to maintain the electrolytic balance. Plasma on the other hand has a composition of water, hormones ,electrolytes, lipids, salts, proteins, fibrinogen, clotting factors, and immunoglobulins.
The blood plasma is a liquid matrix which comprises of proteins, fibrinogen, clotting factors, and immunoglobulins (antibodies) which are not present in the D5NS.

ANSWER QUESTION PLZ TYSM!!
Answer:
Difference: Conductors are materials that permit electrons to flow freely from particle to particle. Conductors allow for charge transfer through the free movement of electrons. In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule.
Similarities: Both conductors and insulators deal with the electric conductivity of a surface or material. Everything is either a conductor or an insulator. It is a conductor if it readily allows electrons to flow across it, when there is a potential voltage differential between two points on the surface.

What is fred's genotype?
Answer:
[tex]x^{h} y[/tex]
Explanation:
Fred has inherited the colorblind trait from his mother. We know this because his spot on the pedigree is filled in. Because he is a male his genotype must be some variation of xy and because he is colorblind he must have the recessive "h" on his x chromosome. So his genotype (genetic type) is [tex]x^{h} y[/tex]

What is RNA primase's job?
-removing a few bases for DNA polymerase
-add a few bases for DNA polymerase
-removing a few bases for helicase
Answer:
The correct answer is - add a few bases for DNA polymerase
Explanation:
A short extended nucleic acid composed of ssRNA molecule. This is a molecule that synthesize a primer initialy and later again lay down a primer after the opening of replication fork by DNA helicase.
It sysntheisze before and after the helicase and follow the helicase in order to prepare for the replication process. Thus, adding a few bases for DNA polymerase is main job of RNA primase.
How would the soil biota be afected by using traditional chemical pesticides and would this difer from using transgenic methods
Answer:
The impact of pesticides on soil biota can be either positive or negative, depending on the type of pesticide used. Genetically modified organisms (GMOs) are generally designed in order to be more resistant to pesticides, thereby GMOs might have a higher impact on the soil biota (however, the evidence is not conclusive and case by case should be evaluated)
Explanation:
Traditional chemical pesticides are chemical substances used to control pests (e.g., insect pests affecting corn yield). Examples of traditional chemical pesticides include 2,4-Dichlorophenoxyacetic Acid, DDT, Atrazine, Chlordecone, etc. The impacts of these traditional pesticides on soil biota are variable according to the type of product used, the rate at which these products are applied, the target/non-target soil biota (e.g., bacteria, algae, fungi, protozoa, insects, nematodes). For example, it has been reported long-term contamination of DDT on soil microflora (i.e., microalgae and cyanobacteria), thereby these non-target species declined with increasing DDT use; however, direct effects on fungi populations were not observed. Genetically modified organisms (GMOs) are organisms whose DNA has been engineered by using molecular biology techniques. In crop improvement, GMO plants are designed to be more resistant to chemical pesticides and also to produce pesticides themselves, for example, Bt crops that produce a toxin from Bacillus thuringiensis (Bt) that can kill insect pests. GMO plants can also be designed to be more resistant to pesticides, thereby affecting soil biota at higher scale values. Nonetheless, it is important to highlight that like chemical pesticides, the effects of GMOs on soil biota are also variable depending on the type of GMO, which pesticide GMO is producing, target/non-target soil species, etc.

If the human genome is three billion base pairs long, estimate the average number of SNPs in the human genome.
Answer: 500,000
Explanation: Friend me!!! :D
SNPs are said to be found in the human DNA. They do occur almost once in every 1,000 nucleotides. There are about 4 to 5 million SNPs in a person's genome.
SNPs is found all over the human genome. It is states that about one SNP is found in every 300 nucleotide base pairs. This shows that that about 10 million SNPs within the 3-billion-nucleotide human genome.

What is the process of Asexual reproduction? Honey Bees
And
What is the process of Sexual reproduction? Honey Bees
Answer:
ASEXUAL
female worker bees are able to reproduce asexually: they lay eggs that are essentially fertilised by their own DNA, which develop into new worker bees. The team sequenced the entire genomes of a sample of Cape bees and compared them with other populations of honeybees that reproduce normally.
SEXUAL
The typical story of reproduction is that males and females of an animal species do it sexually. Generally, that's what honeybees do, too. Sperm from a male drone fertilizes a queen's eggs, and she sends out a chemical signal, or pheromone, that renders worker bees, which are all female, sterile when they detect it.

Which is NOT a force causing plates to move?
ridge push
slab pul
volcanism
ConveCtion
Ob
Plates movement also known as tectonic shift is caused by ridge push, slab pull and convection. Volcanism is not involved in plate movement. Thus, correct option is C.
Which forces causes Plates Movement?The heat within the interior of the planet causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion or tectonic shift.
The forces that drive plate movement includes convection in the mantle, ridge push and slab pull. The heat from radioactive processes within the planet's interior causes the plates to move.
Convection currents are the process in which materials inside the mantle heat up and rise to the surface and the cooler liquid sinks, as the cooler liquid sinks it then heats up and rises again. These currents cause the tectonic shift.
Slab pull is the pulling force exerted by a cold and oceanic plate to plunge into the mantle due to its weight. The theory states that difference in density causes the plate to sink into the mantle.
Therefore, the correct option is C.
