Explanation:

The cardiac conduction system are specialized cardiac muscle cell that are located in the walls of the heart and sends signals to the heart muscle. These signals cause the heart to contract. The main components of this system are AV node, bundle of His, SA node, bundle branches, and the Purkinje fibers.

Answer:

six

Explanation:

There are 6 oxygen atoms present in the products of photosynthesis.

Photosynthesis is a process by which green plants, algae, and some bacteria convert carbon dioxide and water into glucose (a sugar) and oxygen, using energy from light. This process takes place in chloroplasts within the cells of plants and is essential for life on Earth, as it produces the oxygen that other organisms breathe and the food that supports the food chain.

The glucose produced by photosynthesis is used by the plant as a source of energy or stored for later use. Additionally, the glucose can be converted into other sugars, starches, and cellulose, which are used to build plant tissues.

Explanation:

Answer:

ANSWER FOR NUMBER 14 The arrows show in the food web what animals eat/get eaten by, and why the arrows can't point the other way is because if they were to point the other way it would be unaccerate, for example if we switch the arrows that means that a hawk would be eaten by a rat.

Answer: (Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure

(Function) mRNA: carries the information in the DNA to the ribosomes where it is translated into amino acids of proteins, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain during protein synthesis, tRNA: acts as an adaptor molecule, which identifies correct amino acids corresponding to the anticodon present on it

Explanation: Plato, you're welcome

(Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure.

(Function) mRNA: carries the information in the DNA to the ribosomes, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain, tRNA: acts as an adaptor molecule.

mRNA carries instructions from the DNA to the ribosome work site. rRNA forms part of the structure of the ribosome and helps to connect pieces together. tRNA brings in the amino acids, which are the pieces that get strung together to make the final protein.

Moreover, the three major types of RNA are: mRNA (messenger RNA) : it provides the template for protein synthesis during translation, tRNA (transfer RNA) : it brings amino acids and reads the genetic code during translation, rRNA (ribosomal RNA) : it plays a structural and catalytic role during translation.

Therefore, the main difference between mRNA and tRNA is that mRNA serves as the messenger between genes and proteins whereas tRNA carries the specified amino acid into the ribosome in order to process the protein synthesis.

Answer:

It's D

Explanation:

I had it on my quiz

Endosperm regulates seed development and facilitates the transmission of maternal nutrients to the embryo. Therefore, option (D) is correct.

The endosperm is a type of tissue that develops during fertilization and is found inside the seeds of most angiosperm plants. It gives the embryo the nutrients it needs to grow.

Endosperm is produced when the two sperm nuclei that are contained within a pollen grain make their way into the interior of a female gametophyte.

The endosperm contains carbs, protein, and minor amounts of B vitamins and minerals. These components affect our bodies differently: Bran and fiber inhibit starch digestion, preventing blood sugar increases.

Answer:

I guess it would not grow??

Explanation:

Answer:

When plants lose more water than they can take up from the soil, they become water stressed. ... Such drought conditions certainly inhibit the growth of plants. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive, so the long-term effect is that the plant will die if the drought continues.
