When determining the taxon based on morphology, a scientist is relying on genetic similarities. True or False

Answers

The answer is true.

 

In morphology, the scientist relies on genetic similarities in determining taxon based.

Morphology is the branch of science which deals with the study of structure and form of organisms and also the organism’s specific structural features.

From the information provided here, it can be said that both the types of organisms contain exactly the same four nitrogen bases, but in different sequences and numbers. Thu, the correct option is C.

What is the genetic code in different organisms?

The genetic code is a set of rules which defines how the four-letter code of the DNA is translated into the 20-letter code of amino acids in an organism, which are the building blocks of proteins in that organism.

The genetic code is almost completely universal across all the different life forms, with a few minor differences in some of the bacteria such as Mycoplasma and in the bacterial-derived lineages such as mammalian mitochondria and chloroplast of plant cells. The variation is due to the codon usage.

The genetic code consists of the sequence of bases in the DNA or RNA molecules. Groups of three bases form codons, and each codon in this stands for one amino acid. The codons are read in the sequence following the start codon until a stop codon is reached in that sequence. The genetic code is universal, unambiguous, and redundant.

Therefore, the correct option is C.

i'd say C is correct.

A zoology student is investigating whether it is true that the gender of turtles depends on the temperature at which the turtle eggs are kept before they hatch. He will test if turtle eggs incubated at 29–30 degrees Celsius produce females, and eggs at 24–26 degrees Celsius produce males. Which of them is the independent variable?a. time
b. gender
c. species
d. temperature

Answers

I think the correct answer from the choices listed above is option D. The independent variable is the temperature. The dependent variable is the gender. The independent variable is the factor that is being varied and measured in the experiment so it must be the temperature.
d temperature is most likely your asnwer

What is the driving force of photosynthesis

Answers

The driving force of photosynthesis is SUNLIGHT ENERGY.

Green plants have the capacity to manufacture their own foods, through the process of photosynthesis, as the result of chlorophyll which their cells contain. The chlorophyll has the ability to trap the energy from the sun and use it to drive the process of photosynthesis. The major function of sunlight in photosynthesis is to break down the water molecules and turn them into high energy electrons that are capable of forming ATP molecules.

The driving force of photosynthesis is the energy that is contained in sunlight. This energy is transformed to energy that plants and other organisms use to live. 

Which of the following carries amino acids to the site of protein synthesis

Answers

Transfer RNA (tRNA) carries amino acids to the site of protein synthesis.

In general , tRNA is responsible for carrying amino acids to the ribosomes, the site of protein synthesis, during the process of translation. Each type of tRNA molecule is specific to a particular amino acid. The tRNA binds to the appropriate amino acid and delivers it to the ribosome, where it is incorporated into the growing polypeptide chain according to the sequence of codons in the messenger RNA (mRNA) molecule.

This process ensures that the correct amino acids are assembled in the correct order to form a functional protein. Transfer RNA is a type of RNA molecule that plays a crucial role in protein synthesis. It has a unique cloverleaf-like secondary structure, with three important regions: The acceptor stem: This region is at the bottom of the cloverleaf and is where the specific amino acid attaches to the tRNA.

The anticodon loop: This region contains three nucleotides that are complementary to the codon on the messenger RNA (mRNA) during translation.
