How does parental investment help reproductive success
Answer:
Explanation: investment in offspring by the parent that increases the offspring's chances of surviving and hence reproductive success at the expense of the parent's ability to invest in other offspring.
An acid-fast staining method was performed on a bacterial smear using the dyes carbol fuchsin and methylene blue. The resulting stained slide contained only cells that appeared blue when visualized using a microscope. Which of the following could explain why only blue cells were present?
a. No acid-fast bacteria are present on the slide
b. Methylene blue was not used
c. Carbolfuchsin was not used
d. Acid-alcohol was not used
Answer: Only blue cells where present because No acid-fast bacteria are present on the slide. The correct option is A.
Explanation:
Acid fast staining method also called Ziehl-Neelsen (Zn) technique is used in the laboratory to stain samples suspected to contain Mycobacterium species. The Mycobacterium species which includes the M. tuberculosis, M. ulcerans, and M. leprae, do not stain well by the Gram technique, which is a common routine stain in the laboratory. This is because of waxy coating on its cell surface primarily due to the presence of mycolic acid.
The acid fast stain consists of:
--> A primary dye which is the carbol
fuchsin
--> A decolorizer which is the acid alcohol
--> A counter stain which is the methylene blue.
In it mechanism of action on the bacterial smear, when the primary dye is applied,the whole cell will appear red. But after decolorizing with acid alcohol, only acid fast bacteria will retain the red colour of carbol
fuchsin while the red dye from the background cells are removed. Then the counterstain (methylene blue) is applied which is picked up by non-acid-fast bacteria making the cells appear blue under the microscope.
Therefore when the bacteria smear is viewed under the microscope and only blue cells are seen, it means No acid-fast bacteria are present on the slide.

What cell parts are common to all of these cells?
Use complete sentences.
Chlamydomonas
Spirogyra
Elodea
Squamous Epithelium
Answer: All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; and (4). The cells of most Chlamydomonas species are more or less oval and feature a noncellulosic membrane (theca), a stigma (eyespot), and a usually cup-shaped chloroplast. Although photosynthesis occurs, nutrients also may be absorbed through the cell surface. Asexual reproduction is by zoospores. The filamentous masses come to the surface and become visible as slimy green mats. Spirogyra has a cell wall, nucleus, pyrenoid and spiral chloroplasts. This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis). The central vacuole takes up most of the volume of the cell. Squamous cells tend to have horizontally flattened, nearly oval-shaped nuclei because of the thin, flattened form of the cell. Squamous epithelium is found lining surfaces such as skin or alveoli in the lung, enabling simple passive diffusion as also found in the alveolar epithelium in the lungs. brainliest?

Explain the differences between Bacteria and Decomposers?
Answer: Decomposers like bacteria and fungi don't eat their food, they decompose it externally. Also, decomposers consume nutrients on a molecular level while detritivores eat large amount of decaying material and excrete nutrients. ... In addition to fungi, bacteria are also decomposer organisms. brainliest
Explanation:
There are more than 300,000 species of plants that have been identified thus far in the world today; many new species are being discovered each year. In addition to providing most of the oxygen for land animals, plants do many other things for us. you will research the Internet and use reliable and credible scientific websites to investigate a specific plant species and choose a way (other than providing oxygen) that plants are useful to humans. [NOTE: Hot topic plants like Marijuana and Opium are off limits and cannot be discussed.]
Writing a full paragraph (a 150-words minimum) for your initial blog post discussing a specific species of plant and the benefit you chose. Be sure to describe what type of plant it is. Where is it found? How does it impact humans or other species? What role does it play in the ecosystem, etc.?
Answer and Explanation:
We can mention the advantages of the plants of the Fabaceae family, also known as legumes, such as beans, soybeans, peanuts and peas. First, we must mention how these plants have high nutritional values providing high levels of iron and nitrogen that are essential elements for human health. However, a benefit that these planats produce and that is important on a worldwide scale is the fixation of nitrogen in the soil. All living beings need nitrogen in their bodies, since nitrogen is a primary element in the composition of nucleic acids and proteins. Animals are able to ingest nitrogen from the vegetable diet, but vegetables cannot absorb nitrogen from the atmosphere or nitrogen from the soil, because they are not in molecular forms that plants can absorb. To reverse this, farmers put chemical fertilizers on the plantations, but these fertilizers pollute the environment intensely. It is in this scenario that the plants of the Fabaceae family are important. This is because these plants are able to associate with bacteria that can capture atmospheric nitrogen and place it in the soil, in the molecular form that all plants can absorb. This allows plants to have the necessary nutrients for their growth, reduces environmental pollution, decreases spending on agricultural production, promotes correct levels of nitrogen for human consumption and allows agricultural products to be healthier.
