Answer 1

Scientists can determine the exact age of a fossil by a technique called  Radiometric dating. Radiocarbon dating involves the determination of how much carbon is left in the fossil.

In radiocarbon dating, it is possible to determine how much carbon is left in the fossil, by looking at its half-life period.

Radiocarbon dating (also known as carbon dating) refers to the technique aimed at determining the age of a fossil by exploring the properties of a radioactive carbon isotope called radiocarbon.

Radiocarbon or carbon-14 (14C) is a radioactive carbon isotope of carbon that contains 6 protons and 8 neutrons, whose amount in a sample can de be used to determine the age of a given organic material.

how did the psalmist express his awe and thanksgiving to god for his abiding presence and love for him?​

Answers

The Psalmist expresses his awe and thanksgiving to God for his affection by continually singing Him songs of praise.

The simplest way to thank God is to see Him everywhere and appreciate His presence in our life. It's important for us to remember that we are living because of Him.

The Psalms contain powerful quotes for giving thanks and finding blessings. Psalms 1 - 150 showed how the Psalmist was thanking God by singing praises to Him. The unifying theme of Psalms is praise for God.

HELP QUICKLY Why are the deepest high tides so deep and the shallowest low tides so shallow? Hint: how are the Earth, Sun, and Moon aligned?

Answers

There are different kinds of tides. This change occur because  when the gravitational pull of the sun works along with the gravitational pull of the moon on Earth, it leads to the oceans bulging out.

This result above makes the high tides as been little higher and low tides been little lower than normal.

Spring tides are known to be the deepest as oceans levels are highest in this kind of tide. The neap tides are known to be the shallowest.

This often occurs when the moon, earth, and sun are said to be at a right-angled plane.  Therefore, the gravitation pull of the moon and sun on the oceans do counteract each other making its net effect is smaller.

Transcribe the following Strand of DNA:
GTCCTTTACCATCGATTGGAAAACGTTAAAATCCAGTTCCAT

Answers

Answer:

CCGATAGGT

Explanation:

got this for my hw.

Answer:

So the central dogma of molecular biology describes the journey from DNA to protein product:

DNA --transcription--> mRNA --translation--> Protein

Assuming the DNA sequence provided is the template strand (rather than the complimentary coding strand), we start by transcribing the sequence into mRNA starting on the 3' end of the DNA towards the 5' end (which would build the mRNA 5' to 3'). This process involves the enzyme "RNA polymerase," which can only add nucleotides to the 3' end of the mRNA, just like how DNA polymerase can only synthesize DNA in the 5' to 3' direction. The RNA polymerase will bind to the template DNA strand and synthesize the complimentary mRNA, substituting uracil for thymine (since RNA does not contain thymine like DNA).

In terms of transcribing the sequence given to you, we'll have to work backwards + flip it around to get the 5' to 3' mRNA since the DNA is given 5' to 3' rather than 3' to 5'. Due to the length and the fact that we'll have to use triplets in translation anyways, it can help to break the sequence into triplet codons now.

5’-AAG | TTA | ATG | AGA | AAT | CGA | CAT | GGG | GCG | CCG | AAA | GTA | TAA | CCG | TCT | TAG | AAT | AGC-3’

We can then cross out each codon as we transcribe it and flip the sequence to be 5'-3' mRNA:

mRNA: 5'- GCU | AUU | CUA | AGA | CGG | UUA | UAC | UUU | CGG | CGC | CCC | AUG | UCG | AUU | UCU | CAU | UAA | CUU -3'

Normally, mRNA sequences start with "AUG" which is the start codon (and codes for Methionine), but I'll assume this is just for practice translating + transcribing in general. There's also a stop codon before the end but I'll assume the same again.

Translation involves three main steps - initiation, elongation, and termination. Initiation involves the translation ribosome assembling around the mRNA starting at the 5' end start codon, and tRNA carrying an amino acid binding to the complimentary section of the mRNA. As each tRNA attaches and the ribosome moves along the mRNA, the amino acids on each tRNA are bonded into a longer and longer peptide chain and the now amino acid-less tRNA are ejected (elongation). Termination occurs when a stop codon is reached, the ribosome will end elongation and help fold the protein into its final structure.

To translate the mRNA sequence here we'll need an amino acid/mRNA codon chart. I don't believe I can attach an image here, but looking up those exact words should yield the right results in images.

5'- GCU | AUU | CUA | AGA | CGG | UUA | UAC | UUU | CGG | CGC | CCC | AUG | UCG | AUU | UCU | CAU | UAA | CUU -3'

Ala - Ile - Leu - Arg - Arg - Leu - Tyr - Phe - Arg - Arg - Pro - Met - Ser - Ile - Ser - His - STOP - Leu

Amino acids are often abbreviated into three letters (Ala = alanine, Met = methionine, etc), and sometimes are abbreviated as single letters, though I've only seen that for sequencing databases.

In terms of locations for each of these processes, transcription occurs in the nucleus for eukaryotes and translation in the ribosomes/cytoplasm.

Unmanned marine vehicles are useful because they help with marine tasks, completing them in less time, reducing risks, reaching deeper areas.

Unmanned marine vehicles (UMV) are robotic vehicles controlled from afar that allow us to explore the sea and perform tasks with minimum risks.

UMV is useful because:

They substitute people working at the sea in risky tasks,They allow deeper exploration of the sea.They do tasks in less time than humans.

An example of how useful these marine vehicles are is during the construction of ports. They replace divers who have to do the job manually, spending many hours and risking their lives. With a UMV, there is no need for humans to go under the water, experts control the robot from the surface.

In conclusion, UMVs are useful because they are practical tools that save time and reduce risks.

It is the process by which water vapor is converted into liquid water. It is an integral part of the water cycle.

It shows how water continually converts into three forms solid, liquid, gas throughout the earth surface.

The boiling point and the condensation point are same and take place at 100 degrees Celsius.

The temperature range of condensation occurs between 0 degree Celsius to  100  degree Celsius.

In water cycle due to condensation  water molecule  forms a cumulous clouds and fog followed by fall down of water droplets on the  Earth’s surface as precipitation, which is commonly called rain.

Rain water enters the earth’s waterways, soil absorbed by plants or   freeze into its solid form ice form.
