penicillin is harmful for other fungies and fungal diseases?
Answer:
The antibacterial effect of penicillin was discovered by Alexander Fleming in 1929. He noted that a fungal colony had grown as a contaminant on an agar plate streaked with the bacterium Staphylococcus aureus, and that the bacterial colonies around the fungus were transparent, because their cells were lysing.

Explanation:
where do the light-independent reactions take place in cam photosynthesis?
Answer:
Explanation: In plants, carbon dioxide (CO2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells. Once in the mesophyll cells, CO2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis.
The place from where the light-independent reactions occur in cam photosynthesis would be:
Chloroplast stroma
PhotosynthesisThe chloroplast stroma is where CAM photosynthesis takes place. It starts when the plant's stomata open at night, allowing CO2 gas to flow into the cytoplasm of CAM mesophyll cells.
Carbon dioxide is exclusively collected in CAM plants at night, when the stomata open.
Malic acid is turned back to carbon dioxide during the day.
When the sun shines, light reactions produce energy for the Calvin cycle, which allows carbon dioxide to be transformed into sugars.

Linnaeus' classification of life only included two categories: animals and plants. Which three kingdoms did he leave out? ( point)
O Insecta, Fungi, and Monera
O Monera, Bacteria, and Protista
O Fungi, Monera, and Protista
O Bacteria, Insecta, and Protista
Answer:
C
Explanation:
These are the three missing kingdoms
Fungi, Monera, and Protista are the three kingdoms he neglected to mention.
What Linnaeus classification?The Linnaean system is based on similarities in apparent physical qualities. This system is a hierarchy of taxa, from the kingdom to the species. Each species is given a unique two-word Latin name. The domain, which was just added and is a larger taxon, is smaller than the kingdom. Seven levels make up Linnaeus' hierarchical classification scheme. They are kingdom, phylum, class, order, family, genus, and species, in order of largest to smallest. Linnaeus created a hierarchy for nature in Systema Naturae. He suggested that the entirety of nature may be divided into three big categories known as kingdoms. Animals, plants, and minerals made up these three kingdoms. He categorizes each of these kingdoms.To learn more about Linnaeus classification refer to:

Describe an example of how island biogeography principles were used to explain biodiversity changes in areas that were not specifically islands.
Answer:
How Biogeography Affects Biodiversity
Alfred Russel Wallace, Father of Biogeography
Figure 1: Alfred Russel Wallace, Father of Biogeography
Some places contain more species than others. For example, Antarctica has fewer species than a temperate deciduous forest, which in turn has fewer species a tropical rainforest. For over 150 years, researchers have sought to make sense of the gross and fine scale spatial patterns in biodiversity, and to elucidate both the proximate and ultimate causes for these patterns.
This article describes some of the major geographic patterns in species richness, and the processes and theories that are thought to account for these patterns. Much of this knowledge has emerged from the tremendous body of work from one scientist, Alfred Russel Wallace (Figure 1), widely regarded as the “Father of Biogeography.” Aside from co-originating the process of Natural Selection with Charles Darwin, Wallace spent extended periods studying the distribution and diversity of plants and animals in Amazonia and Southeast Asia in the mid 1800s. Many of the patterns and processes featured in this article were initially described by Wallace, and careful study of his work indicates that his ideas presaged many of the discoveries made by his numerous successors.
Many of the spatial patterns in biodiversity are overt, others are subtle and yet additional patterns remain undetected. While the existence of these patterns may be obvious — and changes in the environment that are paired with these patterns may also be obvious — the mechanisms that cause the differences in biodiversity along environmental gradients are under still the subject of scientific debate. Because large-scale patterns are the emergent result of complex interactions at many spatial and temporal scales, no single answer is likely to ever emerge, but with continued research our understanding of the processes shaping these patterns increases.
Historical Processes Affecting Biogeography
Darwin's finches of the Galapagos Islands are a classic example of adaptive radiation.
Figure 2: Darwin's finches of the Galapagos Islands are a classic example of adaptive radiation.
All species occurring in at a given place and time either arrived from another place or originated in that location from ancestral species. This fact applies to extinct species that were ancestors of all extant species. Species richness in a given location is the result of three factors — the rate of speciation, the rate of extinction, and the dispersal of species from other locations. In principle, if biogeographers could understand how the current and past environment has shaped these three factors, we would then obtain a comprehensive understanding of what generates all biogeographic patterns of species richness. However, numerous environmental and organismal parameters can drive these historical factors, in both complex and interacting fashions.
why do most cells in the human body divide infrequently?
antigen-presenting cells usually display processed antigens to t cells in the _____________.
Antigen-presenting cells usually display processed antigens to T cells in the LYMPH NODES. These nodes are regions of the body where lymphocytes are activated.
T cells are white blood cells (lymphocytes), which form part of the immune system.
These cells (T cells) develop in the bone marrow.
The lymph nodes are secondary lymphoid organs in which naive T cells that search for specific antigens examine antigen-presenting cells (APCs) for their activation.
