It is true that r-related species have a short life span and an early reproduction cycle. R-related species also known as r-strategist have a short and simple life span. Due to their simple life span, their nutrient exchange rate with the environment is rapid. Unlike K-selected species, they have the ability to reproduce at a young age. They reproduce a large number of off-springs, but many of their off-springs tend to die before attainment of their reproductive age.
During the S phase, DNA is replicated.
Answer:
The correct answer would be calcium ion and cAMP.
Secondary messengers refers to the intracellular signaling molecules which pass the signals from the receptors located on the surface of the cell to the target molecule present within the cell.
The secondary messengers can be classified into three major class:
- Cyclic nucleotide for example cAMP (cyclic adenosine monophosphate), cGMP (cyclic guanosine monophosphate)
- DAG (diacylglycerol) and IP₃ (inositol triphosphate)
- Calcium ions (Ca⁺⁺)
Hence, from the given options, calcium ion and cAMP would make the correct choice.
<span>Hysterectomy codes are first divided in the CPT manual based on the approach and then on any secondary procedure(s) that were done.
The Current Procedural Terminology (CPT) medical manual set by the American Medical Association (AMA). It contains several codes for each domain, included the surgery, which includes the hysterectomy.
Hysterectomy is a surgical procedure that involves removing all or part of the uterus. It may also involve the removal of the cervix, ovaries, fallopian tubes, and other surrounding structures.

---C---- if brown snails are mostly eaten that most likely means they are more common. If less than snails are eaten then stripedsnails would eventually over populate brown snails and then brown snails would overpopulate striped snails ..... so elminate b and d and snails probably won't go extinct..... so I would have to go with c
