Answer:
D. You believe it rained when you see a mud puddle.
Explanation:
A. is incorrect because an inference is an educated guess, and counting 43 tree rings is a conclusion.
C. is also incorrect because you found the temperature with a thermometer, there was no inference made before checking it.
B. is incorrect; inferences are based on past experiences/knowledge, which looking through a telescope at craters on the moon is not doing. It does not disclose other means of reaching the conclusion.
D. is correct. Using skills of observation, you infer that the mud puddle could have been caused by rain.
You believe it rained when you see a mud puddle is an inference. Thus, option D is correct.
Inference is the process of drawing a conclusion from evidence. It is a type of reasoning that involves using existing information to make educated guesses about missing pieces of information. Inferences can be made in many different contexts, such as in everyday life, in literature, and in science.
In other words, an inference is a conclusion that is drawn from evidence. In this case, the evidence is the mud puddle, and the conclusion is that it rained.

Nucleotides from the DNA template strand complement the mRNA's codons. These codons code for amino acids. Option B is correct. CAA - CTA - TCG
What are nucleotids?Nucleotides are monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.
Several nucleotides joint by their extremes compose the nucleic acids.
Nucleotides have a certain order or sequence in nucleic acids, which is significant since these sequences carry biological information neccesary to carry out cellular functions.
What are codons?Codons are short sequences of three nucleotides that carry genetic information needed to build the protein. These units determine which amino acids are added to the growing chain during the assembly.
More than one codon might code for the same amino acid.
Different sequences of three nucleotides -codons- might code for a different amino acid. This means that the resulting proteins will not be the same, and they will accomplish different functions.
What are the template and coding strand?When DNA molecule unwinds to be transcripted, two single strands get separated,
The coding strandIt receives that name because it is the sequence that codes for each amino acid composing the proteins.
When referring to the coding strand, we are talking about the sequence that turns out to be the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.
The template strand -complementary strand-
This is the one that is used during transcription to synthesize mRNA. The template strand is the one that is going to be complemented by the mRNA.
To get to know the sequence of nucleotides in the template strand that code for the polypeptide sequence val-asp-ser, firts we need to know which codons code for these amino acids.
1)
Amino acid Codon
Val GUU, GUC, GUA, GUG
Asp GAU, GAC
Ser UCU, UCC, UCA, UCG, AGU, AGC
These are all the possible codons in mRNA that might code for these amino acids. Now, we need to identify their complementary bases on the template strand.
2)
mRNA Template strand
GUU CAA
GUC CAG
GUA CAT
GUG CAC
GAU CTA
GAC CTG
UCU AGA
UCC AGG
UCA AGT
UCG AGC

The column of the right shows all the possible nucleotides that might complement the mRNA codons. There are several combinations. Now, we need to choose among the options the correct combination.
3)
Options A and D ⇒ guu-gau-agc and caa-cua-ucg
These are not the correct options since they carry uracils instead of thymines. Remember that DNA molecules have thymine, and RNA molecules have uracil.
Option C ⇒ gtt-gat-agc
This is not correct since these sequences do not complement the mRNA codons.
Option B ⇒ caa-cta-tcg
This is correct. You can find these nucleotide sequences among the options written before for the template strand.

The energy required for organisms to respond to the environment comes from the sun.
What is the importance of the Sun in the ecosystem?Light energy, which also comes from the Sun, is essential for photosynthesis, a process in which green vegetables transform carbon dioxide and water into glucose, lipids, proteins, vitamins, nucleic acids, releasing oxygen into the atmosphere.
The sun is the basis of life, because if we analyze the food chain, its base comes from the photosynthetic beings that provide food for this chain to occur.

A. Earth's atmosphere is deep enough to allow water to cycle through
its solid, gas, and liquid states.
OB. Earth's surface is continually bombarded by comets, which add
liquid water.
OC. Earth's distance from the sun keeps the temperature just right for
liquid water to exist.
OD. Earth's atmosphere is warm enough to prevent water vapor from
condensing.

water boils at 100 degrees Celcius and freezes at zero degrees Celcius. if you want to keep water in a liquid phase, the temperature has to be between 0 and 100 therefore earth is the only planet that is able to keep water in a liquid phase as it is not too hot nor too cold
What of the following will occur after a fire burns down 100 acres of a forest?
Question 2 options:
The forest cannot recover without human intervention
Primary Succession
Secondary Succession
Adaptive Radiation
Secondary Succession will occur after a fire burns down 100 acres of a forest. thus option C is correct.
What is secondary succession?When a disturbance does not completely remove all life and nutrients from the environment, secondary succession occurs.
Despite the fact that fire, flooding, and other disturbances can devastate a landscape, drive away many plants and animals, and reset the biological community to an earlier stage, the habitat remains alive because the soil stores nutrients and seeds that were laid down before to the disturbance.
Buried seeds can sprout soon after the disruption has passed, and some may have a better chance because of less competition and less shading. Some animals may have evolved to deal with a particular disturbance on a regular basis.

Explanation:
Given what you've learned about scientific hypotheses, theories, and laws, do you think a scientific theory can become.
scientific law? Explain your reasoning.
Answer:
No. A law is something that happens without fail every time when being tested, or when it happens in nature. A law does not attempt to explain why the thing occurs, it only states it. A scientific theory is not something that can be tested on and will receive the exact same outcome each time. A theory attempts to explain an action seen in nature. Theories can be subject to change if new scientific data and research comes out, whereas laws cannot.

A. form single covalent bonds.
B. form double covalent bonds.
C. form bonds with oxygen atoms.
D. form bonds with hydrogen atoms.
Answer:
Fats with at least one double bond between carbon atoms are unsaturated fats. When some of these bonds are in the cis configuration, the resulting bend in the carbon backbone of the chain means that triglyceride molecules cannot pack tightly, so they remain liquid (oil) at room temperature.

What are Vascular tissues?Vascular tissues in plants are specialised tissues which transport nutrients and water through the plant. They are made up of two distinct kinds of tissues: xylem and phloem.
Xylem is in charge of carrying water and minerals that are dissolved from the plant's roots to its leaves. It is made up of many cell types, such as tracheids, vessel components, and fibres. Tracheids and vessel elements are long, hollow structures that create lengthy tubes when stacked end to end.
Sugars and other organic compounds are transported from the leaves to the remainder of the plant by phloem. There are two sorts of cells in it: sieve tube elements and cell companions. Sieve tube components are long, narrow cells that run end to end.
