On the outside of the plasma membrane? Acts as signals or makers to help cells recognize one another

Biology

Outside the plasma membrane there is presence of glycoprotein which is a series of polysaccharides to form the cell coat and is used for ID or cell recognition. Each individual has a unique special code for the glycoprotein.

Lerok [7]
Well,  . . 
Let's divide the gallon into 4 Quarts.

if 1 part cleaner need to be mixed every 3 parts of water, it's means  that you need about 1/4 gallon of cleaning solution

hope this helps

Body Type: DNA code- AGTGCCTTC RNA code- ___________ Amino Acid sequence (aka protein)- ___________________ Body Type?- ________
olga2289 [7]

Answer:

The correct answer would be:

  • mRNA sequence - UCACGGAAG,
  • amino acid sequence - Ser-Arg-Lys, and
  • body type - dwarf

By central dogma, we know that nucleotide sequence of deoxyribonuceic acid (DNA) form the amino acid sequence of a polypeptide chain.

Nucleotide sequence of DNA is first decoded in the form of nucleotide sequence of mRNA (messenger ribonucleic acid) under the process of transcription. The sequence of RNA is complementary to the nucleotide sequence of template strand of DNA. In addition, uracil is present in RNA in place of thymine.

tRNA (transfer RNA) then deciphers the codon sequence of mRNA into amino acid sequence of polypeptide sequence by the process of translation.

Now, given DNA sequence is AGTGCCTTC.

so, the mRNA sequence would be UCACGGAAG.

Codon sequence is UCA CGG AAG.

So, the amino acid sequence would be Ser-Arg-Lys.

Hence, the trait of showman performer would be dwarfism.

Codon sequence chart is attached for reference.

ch4aika [34]

Answer:

C.

Explanation:

In the context of evolutionary biology, coevolution refers to the evolution of at least two species, which occurs in a mutually dependent manner. ... An example is the coevolution of flowering plants and associated pollinators (e.g., bees, birds, and other insect species)

Sound quality can be divided
iris [78.8K]
Sound quality can be divided into amplitude, timbre and pitch. If there’s an impedance mismatch between your two devices connected to the single output, you could have a large mismatch between the levels arriving at each device. If the difference is large enough, one device may have distorted or inaudible audio.

To avoid this, you should ensure that both devices connected to the split signal are similar - such as 2 pairs of headphones, 2 recorder inputs, and so on. When you place 2 devices with wildly differing load impedances on a splitter is when you’ll encounter problems - such as headphones on one split and a guitar amp input on the other.

To get around this, you can use either a distribution amplifier (D.A.) or a transformer balanced/isolated splitter - which will work over a larger range of load impedances, typically. Depends on the quality of the splitter and the exact signal path. If you’re using the splitter to hook two things into one input, and you’re using quality connectors, you probably won’t lose much quality. There can be an increase in impedance of the cable due to the imperfect continuity of the physical connection, however with unbalanced line-level signals, impedance at both ends of the chain tends to be orders of magnitude higher than the connection will create, so one split will be barely noticeable. So too, the noise increase from the additional length of cable.

Now, one source into two inputs, that will by basic math and physics result in a 3dB drop in signal strength, which will reduce SNR by about that much. By splitting the signal path between two inputs of equal impedance, half of the wattage is being consumed by one input and half by the other (the equation changes if the inputs have significantly different impedances). So each input gets half the wattage produced by the source to drive the signal on the input cable, and in decibel terms a halving of power is a 3dB reduction. Significant, until you just turn the gain back up. The “noise floor” will be raised by however much noise is inherent in the signal path between the split and the output of the gain stage; for pro audio this is usually infinitesimal, but consumer audio can have some really noisy electronics, both for lower cost and because you’re not expected to be “re-amping” signals several times between the source and output.

How can dominant-lethal alleles be passed down? (Choose the BEST answer!) a. They can’t, as they are lethal.b. They can be passe
Andreyy89

Answer: b

Explanation:

Dominant lethal alleles can be passed down if the individual can live to a reproductive age. The individual can then have children and can possibly pass down the lethal allele
