The 4 divisions of Gymnos:
1- coniferophyte
2- Cycadophyta
3- Ginkgophyta
4- Gnetophyta
Describe
1- Conifers : Pines , firs , redwoods
2- Coniferophyta : seeds , large
3- Cycadophyta : Tropical and subtropical
4- Ginkgophyta : Only living Meso Era survived in China .
I hope that's help !
Answer:
The thoracic cavity is "Superior" to the abdominopelvic cavity. Superior ... If an incision cuts the heart into right and left parts, a "Sagittal" plane of section was used
Explanation:
The thoracic cavity is mainly located in the chest region which also have neck and the diaphragm in it. In the thoracic cage the thoracic organs are safely placed. The thoracic cavity lies above the abdominopelvic region. The sagittal plane is the vertical plane which runs from the front to back of the body. The sagittal plane helps in splitting of two equal halves like the left and right one.
Answer:
It helps cells to make proteins.
It provides a source of water
It provides form of usable Nitrogen.
It removes carbon dioxide from the atmosphere.
It destroys harmful bacteria.
Answer: D) cAMP
Explanation:
In the absence of glucose cell can make use of other sources of carbohydrates such as lactose. In E. Coli and other bacteria utilization of lactose depends on the availability of cAMP. Bacteria accumulate cAMP only when starved. When glucose is exhausted, cAMP is available in plenty.
cAMP is necessary for the gene expression because it binds catabolite repressor protein (CAP) to form CAP-cAMP complex. CAP is a lac repressor the binds to the operator site of the lac operon preventing RNAP From binding to the promoter.
RNA polymerase can bind to the promoter site only when CAP-cAMP formed
Answer: The animal population will have a dramatic increase
