A birdwatcher wants to identify an eastern bluebird. What feature of a bird should the birdwatcher evaluate first to identify an eastern bluebird?

Answers

Answer 1

Explanation:

In this case, I would suggest looking at the overall color of the bird as well as notable color patches on the wings, tail, or the head.

Also note whether or not the edges where colors meet are blurred or smooth/blended.

How and why does the surface of the earth change
of the earth has changed?

Answers

Answer:

How and why does the surface of the earth change

of the earth has changed?

It can be hard to describe change on the surface without bringing up the interior. Earth is a system of constantly changing interactions between interior, surface conditions, and external events.

Volcanoes bring up new material and even create land. The Hawaiian islands, for instance are a chain of volcanoes on the surface, but the underlying structure is a single magma plume. In a way, the entire chain of islands is a single volcano that breaks through different places as the crust moves over it.

On that note: plates. Earth is made of tectonic plates that constantly move. Some grind against one another, others collide, and some pull apart. Depending on direction and interaction, you get anything from mountains, to spreading valleys, oceans, and anything else you care to name. Mountains can almost be viewed as something akin to the ridges of build up ice on a window scraper.

Erosion by water, wind, sand, chemicals, and living things changes the surface too. Materials on the surface face an incredible number of forces breaking them down and dragging them away, even as those same forces in different places and situations deposit those materials in other places, building things back up.

“Stardust” is also a thing. Rocks, dust, debris, and all sorts of random, natural cra.,p is constantly hitting our atmosphere. Regardless of whether or not it stays mostly intact, some material breaks off, and most of it does tend to make it to the surface, adding tiny amounts of matter all the time. …of course something BIG enough hitting the surface can throw rocks and chunks of surface clear into space, so that’s a thing too.

Remember when I mentioned living things? Living things D.,IE! Gac.k! And when they do, they break down into organic gunk. Soil - the stuff we grow crops in - is basically minerals and dead things that are decaying into nutritious, yummy, dir.,t.

Weather changes things too. Rain erodes, but rain that soaks a rock, and then is frozen by low temperatures, breaks the rock. Too much rain can create flooding, which results in a lot of sediment moving downstream. Heat can dry things out, crack the ground, and even slowly cook one kind of soil into another. Lightning can make glass out of sand, snow can collapse weak ground, not enough rain can dry out ground that could si.nk down without the extra pressure, and too much rain can literally move mountainsides if enough water adds its weight to the rocks and dir.t.

It’s always changing, and there is always more complexity to go into when studying it. There’s seldom a single cause, or reason, or effect for anything.

Explanation:

Have a great day!

The surface of the earth is constantly changing.

Explanation:

Wind, water,and ice break down large rocks and move sediments on the surface. Some events, though, change earth's surface much more quickly. These include volcanic eruptions, earthquakes, and landslides.

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.

what is condensation ?

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.

What is the most valid conclusion regarding ocean depth temperature, based on the data? The temperature and salinity increase with increasing depth. The salinity increases as the depth goes closer to zero. The bottom of the ocean is frozen and salinity levels are low. The ocean temperature never rises above 10°C and salinity remains constant.

Answers

The most valid conclusion concerning ocean depth temperature is B. The salinity increases as the depth go closer to zero.

 

Effect of Salinity on Water Depth

Decreasing ocean temperature increases ocean salinity. These occurrences put pressure on water as the water depth increases with decreasing temperature and increased salinity.

 

What is Ocean Salinity?

Ocean Salinity refers to the saltiness or amount of salt dissolved in a body of water. The salt dissolution comes from runoff from land rocks and openings in the seafloor, caused by the slightly acidic nature of rainwater.

 

Thus, the most valid conclusion one can draw regarding ocean depth temperature is Option B.
