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
A molten, sticky rock thant forces its way through a crack in the Earth’s crust
A.Lava
B.Lahar
C.Magma
D.Scoria
Answer:
Magma.
Explanation:
This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth's surface, it is called lava. Like solid rock, magma is a mixture of minerals.

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.

What is an explanation of the endosymbiotic theory?.
Answer:
The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.

To teach an animal to perform a complex sequence of behaviors, animal trainers are most likely to use a procedure known as.
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."

An animal with a digestive _________has only one opening through which they ingest food and expel wastes.
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.
