armigera and Spodoptera litoralis (Lepidoptera: Noctuidae) lacking the Or42 and Orco genes, respectively, could not detect their host plants 42••, 43. After an odorant binds to a receptive OR, it triggers a cascade that sends signals to the brain; moreover, odorants must be deactivated...
Mitosis and cytoplasmic division function in ___. a. asexual reproduction of single-celled prokaryotes b. development and tissue repair in multicelled species c. sexual reproduction in plants and animals 1. Why are cells from a blastula used to examine mitosis? \\ 2. How fast do you think...
There are two main types of reproduction, or how organisms make more of themselves, sexual and asexual. During sexual reproduction gametes from two organisms fuse to make a new cell called a zygote.Answer and Explanation: Somatic cells reproduce asexually. Somatic cells are any cells that are ...
As you might already know,cellsact as the building blocks of life, whether they compose our own tissues or a tree branch outside of your window. Humans, animals and plants have cells with genetic information contained in a type of membrane called a nucleus. These types of cells, called euk...
Natural polyploidy has been known for a very long time in plants, but long considered virtually impossible in nature in animals because of the so-called “Müller's rule” (Müller, 1925), until a few researchers started surveying natural populations for ploidy. Numerous cases of allopolyploid ...
You may not have heard of the euglena, but they are bizarre microscopic creatures. They are a crossover between plant and animal, managing to create food through photosynthesis just as plants do, and eat food like an animal, too. The battle between zooologists and botanists to claim euglena...

If reproduction is not necessary for survival, how did it come into the process of evolution? Why is sexual reproduction important in the evolution of plants and animals? Why don't more species reproduce both sexually and asexually...
How is meiosis similar to mitosis? a. Both produce daughter cells that are genetically identical. b. Both produce daughter cells that are genetically different. c. Both occur in human, other animals, and plants. d. Both occur asexually. ...
