slava [35]
You need to draw a food chain starting with something small like bacteria and and getting back around the loop to bacteria again( explaining what the the previous organism does to the next for example it eats it). Then you need to underline the organisms/animals. Then write in bold the way it got the energy from the previous one( for example if it eats it )

B) Hemoglobin is an oxygen-carrying protein found in red blood cells. Describe the structure of hemoglobin.
likoan [24]

Answer:

B) hemoglobin comprises for subunits each having one polypeptide chain in one heme group. all hemoglobins carry the same prosthetic heme group iron protoporphyrin IX associated with a polypeptide chain of 141(alpha) and 146 (beta) amino acid residues.

C)sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout the body (hemoglobin).

What steps does the cell take to speed the rate of dna replication
Brums [2.3K]

Answer:

Addition of enzymes will increase the speed rate of DNA replication.

Helicase:

It is responsible for DNA strands unwinding and unzip the DNA strands from their center.

Primase:

It is responsible for 5' to 3' direction RNA primers synthesis, okazaki fragment's template.

Polymerase 3:

It synthesize the nucleotides from the 5' to 3' direction on leading end.

Polymerase 1:

It synthesize the nucleotide (okazaki fragments) on lagging strand.

Ligase:

It connects all okazaki fragments.

Topoisomerase:

Topoisomerases are used to regulate the super coiling.

Svetlanka [38]

Most efforts to identify interhemispheric differences in brain anatomy have focused on the size of three areas of cortex that are important for language, namely: the planum temporale, the frontal operculum, and  Heschl's gyrus.

One distinguishing feature of the way the human brain is organised is hemispheric specialisation, often known as cerebral dominance or lateralization of function. The Sylvian fissure's cortical region directly behind the auditory cortex (Heschl's gyrus) is known as the planum temporale.

Wernicke's area, one of the most significant functional areas for language, is centred in a triangle zone. The area of the frontal lobe that, in primates, covers the rostrodorsal region of the insula is known as the frontal operculum.

Therefore, three areas of cortex that are important for language are: the planum temporale, the frontal operculum, and  Heschl's gyrus.
