Answer: cell membrane
Explanation: Substances that were produced inside the cell that have to get out of the cell have to go through the cell membrane, because the cell membrane is the structure of cell.
Answer: C) GMOs, genetically modified foods engineered in a lab to produce desirable traits.
Explanation:
The genetic engineering involves the insertion of genes from other organism to the host organism so as to make up genetically modified organism. Some unwanted and default genes are also removed from the organisms so that their body function properly.
The genetically modified foods are the examples of genetic engineering. This is done to produce desirable traits in the food crops. In plants both plants and animal genes are inserted to improve the yield of crops, and to improve their quality. In animals, the insertion of genes of other animals is likely to improve the milk and meat yield.
Answer:
We can determine the past arrangement of leaves on a bare twig by looking at the arrangement of axillary buds and leaf scars.
Explanation:
- The arrangement of leaves on a branch or stem is called phyllotaxy.
- Leaves are formed at stem nodes.
- They bear axillary bud on their axil.
- Axillary bud give rise to flowers and new branches.
- When leaves shred off we can determine their phyllotaxy by looking at the axillary buds on the nodes.
- When leaves fall off the stem, they leave scars at the nodes, these scars can also be considered to find out the attachment of leaves and phyllotaxy.
Common leaf arrangements are:
- Alternate.- When one leaf arises at each node and successive leaves develop on alternate sides .se.g. As seen in Barberry
- Opposite- When two leaves arise at one node and on the opposite side of the stem. E.g as seen in maple.
- Whorled.- When three or more leaves arise at a node forming a whorl.
