One of the functions of the muscular system is pumping blood. <span>The cardiac muscles in our body control the pumping of blood throughout arteries and veins. The contraction of the heart muscle is involuntary and is controlled by the hearts own electrical system. The right side of the heart receives blood from the body and pumps it to the lungs. The left side of the heart receives blood from the lungs and pumps it out to the body.</span>
The correct answer is d.) protista
Answer:
The correct option is A) laws that banned the hunting of passenger pigeons to sell in new markets
Explanation:
All other options describe ways that enabled passenger pigeons' extinction. Laws to ban hunting these pigeons had the opposite effect, that is saving the species from extinction.

Answer:
If radioactive deoxythymidine triphosphate (dTTP) is added to a culture of rapidly growing bacterial cells, you will find the greatest concentration of radioactivity in the Nucleoid.
Explanation:
Deoxythymidine triphosphate (dTTP); is one of the four nucleoside triphosphates that are used in the in vivo synthesis of DNA. Unlike the other deoxyribonucleoside triphosphates, thymidine triphosphate does not always contain the "deoxy" prefix in its name
Radioactivity; decay is the process by which an unstable atomic nucleus loses energy by radiation
Answer: 4/16 yellow Labradors, 9/16 black Labradors and 3/16 brown Labradors.
Explanation: Two dihybrids would have BbEe alleles. Using Mendel's chess table of independent segregation to show the offspring, we have the following results:
BBee - 1/16 - yellow
BBEe - 2/16 - black
BBEE - 1/16 - black
BbEe - 4/16 - black
Bbee - 2/16 - yellow
BbEE - 2/16 - black
bbEe - 2/16 - brown
bbEE - 1/16 - brown
bbee - 1/16 - yellow
If the offspring presents B_E_ phenotypes, it will have black pigment deposition. If the offspring presents bbE_ phenotypes, it will have brown pigment deposition. Otherwise, if it presents _ _ee phenotypes, there won't be any pigment deposition, therefore they are yellow.
Adding up all the phenotypes ratios, we have <u>4/16 yellow Labradors, 9/16 black Labradors and 3/16 brown Labradors</u>.
