The dorsal side of the frog is the back of the frog, where the spine is.
Answer:
Seeds are the result of plant reproduction. ... When pollen lands on the flower's stigma, it germinates and forms a pollen tube, which then quickly grows towards the plant's ovary. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation.
Explanation:
Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.
There are several key differences between prokaryotic and eukaryotic cells. Eukaryotic cells are found in multicellular plants and animals, whereas prokaryotic cells are found in bacteria and archaea which are ususlly unicellular. I have summarised the key differences below:
Prokayotic cells do not have membrane-bound organelles, such as the endoplasmic reticulum or mitochondria.
Prokaryotic cells do not have a nucleus, instead they have circular DNA that is free in the cytoplasm.
Prokaryotic cells have smaller ribosomes than eukaryotic cells.
Prokaryotic cells have a cell wall. Their cell wall is made from a different material to a plant cell, a glycoprotein called murein.
Prokaryotic cells may also have a protective layer called a capsule, flagellum to aid in movement and one or more plasmids.
Answer: they can be both
Explanation:
Because protozoan and fungi are eukaryotic and bacteria are prokaryotic
Answer:
The three basic types of adaptations, based on how the genetic changes are expressed, are structural, physiological and behavioral adaptations. Most organisms have combinations of all these types.
Explanation:
Living things are adapted to the habitat they live in. This is because they have special features that help them to survive. The development of these special features is the result of evolution due to gene mutation. These mutations aid in the survival and reproduction and passes on from one generation to the other.
