Answer:
a. hox genes.
Explanation:
HOX genes have the following functions:
- HOX genes are the homeobox subset.
- They specify the areas of the embryo's body plan along the animal head-tail axis.
- They are encoding Hox proteins that specify the position characteristics and ensure that the right structures form at the right position in the body.
- They regulate high-level executive genes, such as transcription factors and intracellular signaling molecules, which adhere, number, form, and growth to cells.
The vertebrates are highly preserved.
The clusters and other genes occur uninterrupted.
Evolutionary, the heterogeneous regulatory areas between the genes most previously present are larger and more preserved than those present at the other ends of the clusters.
The characteristical feature is that these are homeodomain proteins with a highly preserved area of DNA binding encoded with homeobox gens.
Answer:
On the Moon, regolith occurs as a mixture of powdery dust and broken rock. Lunar regolith is formed by the impact of meteorites on the body's surface. The force of the collision melts some of the impacted regolith to form objects known as agglutinates and heaves debris (ejecta) outward from the point of impact. need brainliest pls
Explanation:
I think d is the correct answer or not
Answer:
Yes, it can hurt one depending on the species, such as land animals having to be in the water for too long, it may drown, but it takes a certain amount of time to do so which means that for the most part, it is harmless.

The answer is an abdominal cavity.
The abdominal cavity refers to a space that comprises various essential organs including the stomach, the lower part of the esophagus, colon, small intestine, gallbladder, liver, rectum, bladder, spleen, and kidneys.
The abdominal cavity is a big cavity found in humans and various other animals. It is a component of abdominopelvic cavity. It is situated above the pelvic cavity and below the thoracic cavity. Its dome-shaped roof is the thoracic diaphragm, a thin sheet of muscles beneath the lungs, and its floor is the pelvic inlet, opening into the pelvis.
