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:
i will try my best here goes
Explanation:
i believe it is O Cytokinesis in an animal cell because there is the formation of a cleavage furrow.
Answer:
No. Instead they contain enzymes.
Answer:
Oil and gas production are among the main culprits of air pollution – one of the world's biggest killers according to the United Nations. When fossil fuels are burned by power plants, automobiles and industrial facilities, they generate toxic gases.
<h2>Co-evolution </h2>
Explanation:
A series of reciprocal adaptations in predator and prey populations describes co-dependence or co-evolution
- In co-evolution, two species which are in association evolve together due to their relationship
- Both the species have different ancestry
- Interactions exhibited by co-evolution are: host parasite interaction, prey predator association, evolution of long proboscis in insects for taking nectar from flowers
- Predation is a very short term behavior in which two different species interact with each other for the demand of energy, one is prey and the other is predator
- For successful predation, predator wants minimum energy investment and maximum energy
- Increase in prey population in any given area attracts predator population, hence population of predator also increases in that area
- Increase in predator population results in decrease in prey population after some time decrease in prey population leads to decrease in predator population also
