Answer:
Sun is classified as a G2 V star, with G2 standing for the second hottest stars of the yellow G class of surface temperature about 5,800 kelvins (K) and the V representing a main sequence, or dwarf, star, the typical star for this temperature class.
Answer:
According to NASA, the sun's temperature ranges from roughly 27 million degrees Fahrenheit (15 million degrees Celsius) in its core to just around 10,000 degrees Fahrenheit (5,500 degrees Celsius) at its surface.
The Sun is classed as a G2 V star, with G2 denoting the second hottest stars in the yellow G class—surface temperatures of roughly 5,800 kelvins (K)—and the V denoting a main sequence, or dwarf, star, which is the most common star in this temperature range.

What is genetic biodiversity?
Genetic biodiversity refers to the variety of genes and genetic traits that exist within a population or species. It is a fundamental aspect of biodiversity, as it underpins the ability of species to adapt to changing environmental conditions and to maintain resilience in the face of threats such as disease, climate change, and habitat loss.
Genetic biodiversity arises from mutations, genetic recombination, and other processes that generate new genetic variation within populations. This diversity provides the raw material for natural selection to act upon, allowing organisms with advantageous traits to survive and reproduce.
Genetic biodiversity is important for ecosystem functioning and for the conservation of species, as it helps to ensure that populations are able to adapt to changing conditions and maintain their long-term viability. The loss of genetic biodiversity can have significant negative impacts on populations and ecosystems, making it an important focus of conservation efforts.

Describe how a carbon atom is released from a fossil fuel like coal and travels into the atmosphere as a gas. How does it then end up in living things like plants and animals? Explain how carbon ends up back in the ground. Use the following terms in your typed response: CO2, C6H12O6, atmosphere, lithosphere, hydrosphere, biosphere, carbon sink, carbon source.
Explanation:
Animals and plants need to get rid of carbon dioxide (c02), this process is called respiration. Respiration happens when the plant/animal breaths in air and releases it as carbon, carbon then moves from fossil fuels to the atmosphere where they are burned. When humans burn fossil fuels to power cities, power plants, cars, and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
What is it called when an aquifer gets refilled/replenished? if you answer correctly i’ll make you brainliest:)
Answer:
A recharge zone usually occurs at a high elevation where rain, snowmelt, lake or river water seeps into the ground to replenish the aquifer. A discharge zone can happen anywhere. ... Many people with wells are accessing an unconfined aquifer layer for drinking water. This can be an issue when there is a drought.

All Archaea and bacteria are microscopic, prokaryotic organisms. However, Archaea and bacteria differ in significant ways. Which of the following is the MOST important reason that Archaea and bacteria belong to separate biological domains?
Archaea are often resistant to antibiotics
O Archaea do not have a nucleus
O Archaea are found as single cells or colonies
O Archaea often live in more extreme conditions than bacteria
The most important reason that Archaea and bacteria belong to separate biological domains is Archaea often live in more extreme conditions than bacteria.
What are the examples of biological domains?There are three domains of life, the Archaea, the Bacteria, and the Eucarya. Organisms from Archaea and Bacteria have a prokaryotic cell structure, whereas organisms from the domain Eucary encompass cells with a nucleus.
Examples include memory, mate choice, relationships between kin, friendship and cooperation, parenting, social organization, and status.
This phylogeny overturned the eukaryote-prokaryote dichotomy by showing that the 16S rRNA tree neatly divided into three major branches, which became known as the three domains of (cellular) life: Bacteria, Archaea and Eukarya.

How can we tell histologically that skeletal muscle tissue is highly vascular?
Answer:Muscle tissue is composed of cells specialized for contraction. Muscle is classified into three types according to their structure and function:
Skeletal muscle cells - striated, voluntary control
Cardiac muscle cells - striated, involuntary control
Smooth muscle cells - nonstriated, involuntary control
Skeletal and cardiac muscle cells are called striated because they show an alternating series of bands. The repeating arrangement of their basic contractile unit, the sacromere, produces these striations.
In all types of muscle, contraction is caused by the movement of myosin filaments along actin filaments.
The terms muscle cell and muscle fiber are synonymous.

Sexual reproduction in animals depends on the production of gametes.
Which of these processes produces gametes in animals? *
Mitosis
Fertilization
O Meiosis
Binary fission
The process that produces gametes in animals is meiosis.
What is MeiosisMeiosis is a specialized type of cell division that occurs in the reproductive cells, or germ cells, of animals. It involves two rounds of cell division, resulting in the production of four haploid daughter cells, each with half the number of chromosomes as the parent cell.
During meiosis, the genetic material is shuffled and recombined through processes such as crossing over and independent assortment. This genetic variation contributes to the diversity of offspring produced through sexual reproduction.

Explain enzyme-substrate specificity.
[tex]\purple{\tt{\huge{Answer}}}[/tex]
substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.
Answer:substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.
Explanation:Enzymes and substrates share specificity in that an enzyme will only react with a specific substrate • This is because the active site is complementary in both shape and charge to a given substrate • The model by which this is known is ‘lock and key’ as the substrate is a precise structural fit for the enzyme, much like a lock and key • When the enzyme and substrate bind, they form an enzyme-substrate complex, before the substrate is catalytically converted into a product

Which evolutionary mechanism increases inheritable variations
Recombination of genes
Bottleneck ig of genes
Gene flow
Genetic drift
Answer:
Recombination Of Genes
Explanation:
Recombination of the gene's evolutionary mechanism increases inheritable variations, hence option A is correct.
What are genetic variations in a population?Gene flow, recombination, and mutation are mechanisms that enhance genetic variety. There are more mechanisms that work to promote genetic diversity, but fewer that work to reduce genetic diversity.
Demographic bottlenecks tend to decrease genetic diversity by intensifying genetic drift, but because genetic drift is random and has local impacts owing to recombination, mutation, and selection, the overall impact may vary along the genome.
Because it introduces new variety into the population, the mutation is the only mechanism of evolution mentioned that increases the amount of genetic variation. Genetic drift is the haphazard loss of genetic variation over time.
Therefore, option A is correct.

Which of these factors affects how fast a sound wave moves? the kind of material it is moving through the kind of material it is moving through the amplitude of the sound wave's vibrations the amplitude of the sound wave's vibrations the wavelength of the disturbance in the medium the wavelength of the disturbance in the medium the type of motion that caused the sound wave to form the type of motion that caused the sound wave to form
Answer:
the kind of material it is moving through
Explanation:
Sound wave is a type of mechanical wave, which requires a medium to travel, unlike longitudinal waves that can travel through vacuums. Since, sound waves travel through mediums, the KIND OF MEDIUM/MATERIAL it is traveling through has a role to play on how fast it moves.
Sound waves move faster in materials whose molecules are closely packed together than those with loosely packed molecules. This is why sound waves naturally travel faster in SOLID materials. Therefore, the the kind of material the sound wave is moving through affects how fast it moves.
