What are the reproductive structures of gymnosperms? What are the characteristics of the phylum Anthophyta? What characteristics do algae share with plants? What are the characteristics of the phylum Chordata? What are the general characteristics of the phylum Annelida?
An ecosystem is a community held together by complex interactions between the biotic and abiotic factors in a given area. The biotic factors of an ecosystem are the living portions such as plants, animals, bacteria and fungi. The abiotic factors include the soil, water and other nonliving items...
Spores are the main reproductive units for fungi and are usually single cells. They may be produced either directly by asexual methods or indirectly by sexual reproduction. Spores are commonly formed by the fragmentation of the mycelium or within specialized structures (sporangia, gametangia, sporo...
Antheridium: A Multicellular sex organ in the male that produces sperm. An antheridium is just like a testis in human males because both generate haploid sperm cells. Both antheridia and archegonia are normally microscopic structures. Are gemmae haploid or diploid? The gemmae are small discs o...
Tetraspores are red algae spores produced by the tetrasporophytic (diploid) phase in the life history of algae in the Rhodophyta as a result of meiosis. The
“unhealthy bodies” beautiful is a disservice, becausecriticisms of weight can motivate overweigh people to improve their bodies and, ultimately, their health. One difficulty with this argument against body positivity lies in the assumption that bigger bodies are not healthy, but “bigger” is ...
Asexual reproduction in fungi occurs by what process? A. Binary fissionB. MeiosisC. Nuclear fusionD. Mitosis Fungal Mating Types: Fungi are capable of both asexual and sexual reproduction. When undergoing sexual reproduction, there are not "male" or "female" ...
These lymphocytes are one of many types of leukocyte, or white blood cell. The immune system also includes the spleen, the bone marrow and a gland called the thymus. The immune system can learn to recognize antigens— proteins on the surface of bacteria, fungi and viruses — and alert the...
C. globosumis the species most commonly found indoors. This species is of particular interest because it appears to produce mycotoxins, compounds which are detrimental to human health. These fungi have been definitively linked with allergies in people who are sensitive to molds, and they appear to...
So, Mean, Median, Mode - what exactly are they and how are they different from one another? We hear about them a lot, and three of them feel somehow related. However, each has a distinct role in helping us make sense of data sets and numbers more easily. While we won’t go into ...
