Where does transcription take place & what form of rna plays a role?.
Answer:
Brainliest pls
Explanation:
That's because transcription happens in the nucleus of human cells, while translation happens in the cytosol. Also, in eukaryotes, RNA molecules need to go through special processing steps before translation.

A random mutation occurs and the gga code on this change to CGA what effect does the substitution have on the amino acid being called for explain your answer
Answer:The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.
Explanation:Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into messenger RNA, called point gene mutations.
In the case presented, the substitution of the guanine base by cytosine in the GGA codon —resulting in a CGA codon— generates a change in the coding amino acid, resulting in arginine instead of glycine.
The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.
Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.

Which of the following are types of matter?
Check all that apply.
A. Substance
B. Mixture
C. Force
D. Compound
E. Sunlight
SUBMIT
Answer:
Explanation:
Gravity: You can feel its effects and it is associated with mass, yet it doesn't consist of matter. Memories: Like emotions, these are non-matter. Dreams: Again, you can't weigh them on a balance or enclose them in a container. Magnetism: Forces, in general, are not matter.
most matter is a mixture: It is composed of two or more types of matter that can be present in varying amounts and can be separated by physical means. Heterogeneous mixtures vary in composition from point to point; homogeneous mixtures have the same composition from point to point.
A substance is simply a pure form of matter. In other words, a substance is a matter that contains only one type of atom or molecule. Pure substances can be further divided into two sub-categories: elements and compounds.
Note that a compound: consists of atoms of two or more different elements bound together, can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means), has properties that are different from its component elements, and.
No, sunlight is not a matter because it does not occupy space. Sunlight is a form of electromagnetic radiation and is made of small particles called photons.

Answer:
Traits controlled by a single gene with more than two alleles are called multiple allele traits. An example is ABO blood type. Your blood type refers to which of certain proteins called antigens are found on your red blood cells.
Explanation:
Study Island
A marine biology team is studying a marine ecosystem near a shallow coral reef. For their study, they install ten stations, each supplied with a thermometer and a video camera. The thermometers measure the water temperature, and the video cameras monitor the activity of the fish in each location.
The team takes turns watching the video and determines the average activity of the different fish species at different water temperatures over many months.
After the study, the team reports the average activity and not the actual number of active fish because
A. they ran out of time to watch all the video.
B. they were too lazy to count all the fish.
C. average measurements simplify a complex system.
D. the average of a system is more complicated to measure.
Answer:
D: Average measurements simplify a complex system
Explanation:
"A marine ecosystem is too complex for anyone to accurately measure the exact number of active fish. Instead, a limited number of measurements is used to find a reliable average.
Averages help to simplify a complex system and make it more understandable. When a system is very complex, people depend on summaries, averages, and examples to improve their understanding of the system."

Write a claim predicting the future effect of global carbon emissions on Earth’s systems. Use evidence from the data and models to support your claim, along with reasoning as to how the evidence supports your claim.
Explanation:
Gregor Mendel knew how to keep things simple. In Mendel's work on pea plants, each gene came in just two different versions, or alleles, and these alleles had a nice, clear-cut dominance relationship (with the dominant allele fully overriding the recessive allele to determine the plant's appearance
Osmosis is the movement of what molecule
Answer: Osmosis is the movement of solvent molecules through a semi-permeable membrane from a region of low solute concentration to a region of higher solute concentration. It does not require energy for movement and thus are the passive type of movement.

Answer:
Nerve cells, blood cells, and reproductive cells are examples of specialized cells.
Explanation:
Nerve cells consist of three components: the cell soma, dendrites, and axon.
Blood contains cells, proteins, and sugars. The middle white layer is composed of white blood cells (WBCs) and platelets, and the bottom red layer is the red blood cells (RBCs).
Gametes are an organism's reproductive cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.

A sediment core from an ocean-going ship called the JOIDES Resolution found evidence of what type of event?
Mass flood
Earthquake
Asteroid impact
Volcanic eruption
Answer: What is the JOIDES Resolution? The JOIDES Resolution (JR) is a research vessel that drills into the ocean floor to collect and study core samples. Scientists use data from the JR to better understand geology, and Earth’s history.
Explanation: Deep ocean sediments generally have the poorest resolution, on the order of a thousand to five thousand years. Coastal ocean and sea sediments typically have resolutions of a century to a millennium, while lake cores can provide resolutions of a decade to a century
Sediment cores can provide evidence of a variety of events, including those listed (mass floods, earthquakes, asteroid impacts, volcanic eruptions), as well as other geological and environmental changes.
What is a sediment core?A sediment core is a cylindrical sample of layered sediments taken from the ocean or lake floor using a hollow coring tool. These cores can provide a record of the environmental conditions and changes that have occurred over time.
Layers of sediment can contain materials such as fossils, organic matter, and minerals that can be used to determine past climates, sea levels, and even the occurrence of geological events such as earthquakes and volcanic eruptions. Sediment cores can be analyzed using a variety of techniques, including radiocarbon dating and microfossil analysis.
