The excretory structures of terrestrial arthropods are slender projections from the digestive tract that are attached at the junction of the midgut and hindgut. These are called:.
The excretory structures of terrestrial arthropods are slender projections from the digestive tract called malpighian tubules.
What are Malpighian tubules?The malpighian tubules are channels in the digestive system of the alimentary canals present in arthropod species.
The Malpighian tubules function to provide an excretory system and osmo-regulatory system to arthropods.
These slender tubules are fundamental for the survival of many species of insects (i.e., arthropods).

What are two lesser-known functions of the kidneys (via released hormones and
prostaglandins)?
reproductive cell transportation and bone marrow production
aiding in digestion and extracting carbon dioxide from blood
white blood cell production and repairing nerve cells
O red blood cell production and destroying pathogens
I believe the answer would be aiding in digestion and extracting carbon dioxide from blood.
Explanation: Bone marrow production stops when a child reaches maturity. White blood cells are produced from bone marrow, and O red cells are produced from red bone marrow, leaving the only answer left by process of elimination as B. Kidneys are also responsible for keeping ph balance, sodium and electrolyte balance, along with the balance of other vitamins and minerals in the blood.
If the ability to roll one’s tongue is dominant (r) and the inability to roll one’s tongue is recessive (r), what are the possible genotypes for someone who can roll their tongue? only rr rr and rr rr and rr only rr
The possible genotypes for someone who can roll their tongue are RR or rr, where the R allele is dominant over the r allele.
What do you mean by Genotypes?Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for a particular study or interest.
If R represents the dominant allele and a person rolls their tongue having this allele, while the r represents the recessive allele and a person can not roll their tongue having this allele. To roll their tongue, a person needs only one dominant allele. Thus the person could have genotypes of RR or Rr.
Therefore, the possible genotypes for someone who can roll their tongue are RR or rr, where the R allele is dominant over the r allele.
