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.

Answers

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 a push or pull that can cause motion known as

Answers

Answer: A force is a push or a pull that causes an object to move, stop, or change speed or direction.  Every time you push or pull something you apply a force. Forces transfer energy.

Explanation: In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

A push or pull that an object experiences as a result of interacting with another item is known as a force. Every time two items interact, a force is exerted on each of the objects.

Therefore, A force is a push or a pull that causes an object to move, stop, or change speed or direction.  Every time you push or pull something you apply a force. Forces transfer energy.

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

Answers

Archaea often live in more extreme conditions that bacteria
Archaea does not have a nuclei which is a prokaryote. It rapidly moves to different areas . I hope I’m right

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?

Answers

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.

what is a roan color in cattle is controlled by codominant genes for both red and white hair. if a roan cow is crossed with a white bull, what percentof offspring would be white?

Answers

Answer:

50%

Explanation:

Roan color is controlled by two codominant alleles. Let us assume that the red color allele is R and the white color allele is W. Thus, the roan color would be RW.

Roan color cow is crossed with a white bull;

    RW   x   WW

RW   RW   WW   WW

RW = roan = 50%

WW = white = 50%

1/2 or 50% of the offspring would be roan color while the remaining 1/2 or 50% would be white in color.

Sexual reproduction in animals depends on the production of gametes.
Which of these processes produces gametes in animals? *
Mitosis
Fertilization
O Meiosis
Binary fission

Answers

I believe it’s O Meiosis

The process that produces gametes in animals is meiosis.

What is Meiosis

Meiosis 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.

Which evolutionary mechanism increases inheritable variations

Recombination of genes
Bottleneck ig of genes
Gene flow
Genetic drift

Answers

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.

Answers

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.
