Answer:

The correct answer is option A (Dead plants and animals).

Explanation:

Fossil fuels are hydrocarbon-containing materials like natural gas, fuel oil, coal which act as a source of energy. These fossil fuels are formed from the remains of dead animals and plants of Carboniferous Period about 360 to 286 million years ago.

At that time the remains of plants and animals along with micro-organisms were decayed which were later covered by sand and silt and trapped it under the rocks. Over time heat and pressure compressed it and changed it into coal, oil and some trapped pockets of gases known as natural gas.

Thus, option A (Dead plants and animals) is the correct answer.

Which statement accurately describes how scientists collect data

Debora [2.8K]

Answer:

The statement that accurately describes how scientists collect data is the method used to collect data depends on the desired data.

Explanation:

When a scientist decides to conduct research, he or she must consider the purpose of the research and the best way to conduct it. Once the purpose of the research has been defined and the hypothesis has been put forward, data collection becomes one of the most important steps.

Data collection must be adapted to the needs of the phenomenon to be studied, taking into account the most appropriate and reliable methods to achieve the objective.

<em>An adequate data collection method means choosing the best option to collect the necessary information and obtain the expected results in the investigation.</em>

g 20. Name two bones connected by an interosseous membrane found in the crus and/or sural region. Which one is the medial bone

slamgirl [31]

Answer:

Tibia and fibula. Tibia (medial bone)

Explanation:

The tibia is the medial bone of the lower leg (it is the second-largest bone next to the femur), whereas the fibula is the lateral bone of the lower leg. The tibia functions to transmit the majority of the force in the lower leg. The tibia articulates at the proximal end with the femur and fibula; where this bone (tibia) articulates at the distal end with the fibula and the talus bone of the ankle. The tibia and fibula are connected via an interosseous membrane, which is a thin sheet of connective tissue that spans the space between two bones.

Which of the following accurately describes nutrient limitation?

Studentka2010 [4]

When an ecosystem has a scarce nutrient, that is when there is a nutrient limitation.

So the answer is C. <span>Nitrogen is typically the limiting nutrient in freshwater environments.

This is because Nitrogen is the "scarce" nutrient </span>

Answer:

A transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length,that serves as the physical link between the mRNA and the amino acid sequence of proteins. Transfer RNA does this by carrying an amino acid to the protein synthetic machinery of a cell (ribosome) as directed by the complementary recognition of a 3-nucleotide sequence (codon) in a messenger RNA (mRNA) by a 3-nucleotide sequence (anticodon) of the tRNA. As such, tRNAs are a necessary component of translation, the biological synthesis of new proteins in accordance with the genetic code.

Each mRNA molecule is simultaneously translated by many ribosomes, all reading the mRNA from 5′ to 3′ and synthesizing the polypeptide from the N terminus to the C terminus. The complete mRNA/poly-ribosome structure is called a polysome.

tRNAs in eukaryotes

The tRNA molecules are transcribed by RNA polymerase III. Depending on the species, 40 to 60 types of tRNAs exist in the cytoplasm. Specific tRNAs bind to codons on the mRNA template and add the corresponding amino acid to the polypeptide chain. (More accurately, the growing polypeptide chain is added to each new amino acid bound in by a tRNA.)

Therefore, tRNAs are the molecules that actually “translate” the language of RNA into the language of proteins.
