Answer: Other benefits that a capsules can give to bacteria includes:
--> slowing the penetration of antibiotics or chemicals,
--> it helps bacteria to adhere to surfaces
--> it prevents them from drying out as it contains water components.
Explanation:
Most microorganisms such as bacteria, virus, and parasites, are free living that benefits both plants and animals. The microorganisms that have the ability to cause disease are called pathogens. Infection occurs when pathogens are able to establish itself in a person through the use of its virulent factors. A typical example of virulent factors include the CAPSULES.
Capsules are made up of polysaccharides which lines the outer layer of a bacteria cell envelope. Example of such bacteria includes:
--> Streptococcus pneumoniae,
--> Klebsiella pneumoniae,
--> Haemophilus influnzae, and
--> Neisseria meningitis
These bacteria secrete a capsule around their cell wall which helps to prevent opsonization and phagocytosis by phagocytes of immune system of the host. This helps them to survive and cause disease. Other benefits that a capsules can give to bacteria includes:
--> slowing the penetration of antibiotics or chemicals,
--> it helps bacteria to adhere to surfaces
--> it prevents them from drying out as it contains water components.

What are some Non-examples of a Fossil record?
Answer:
Explanation:
A fossil record is a group of fossils which has been analyzed and arranged chronologically and in taxonomic order. Fossils are created when organisms die, are incased in dirt and rock, and are slowly replaced by minerals over time. What is left is a mineral impression of an animal which once existed. Many fields and specialties are utilized to categorize and arrange these fossils, including comparative anatomy, radiometric dating, and DNA analysis. Using the data from the fossil record, scientist try to recreate phylogenies, or trees describing the relationships between animals, both alive and extinct. The fossil record helps inform how different groups of animals are related through evolution.
Answer:
Fossils are the geologically altered remains of a once-living organism and/or its behaviour. There are two main types: body fossils represent all or part of the organism’s body, and trace fossils show evidence of the organism’s behaviour. The study of fossils is called paleontology, from the Greek meaning ‘ancient (paleo-) being (onto-) study (-logy)’. Scientists who study fossils are called paleontologists. Fossils are of particular interest to geologists as they can help determine the age of a particular rock compared to other rocks, or identify the environment in which the rock was formed.
what is Otis’s gene versions for body color
Answer:
giao
Explanation:
To assist in completing this question, you may reference the Animated Technique Video - Gel-Filtration Chromatography. Consider a mixture of four proteins with various molecular weights. A histone molecule weighs 15 kDa, a p53 molecule weighs 53 kDa, an actin molecule weighs 42 kDa, and an IgG molecule weighs 150 kDa. Arrange the molecules in order of their elution from a gel filtration column
Answer:
IgG molecule, p53 molecule, actin molecule, histone molecule
Explanation:
In a Gel-Filtration chromatography, the larger molecules elude faster from the gel than the small ones.
In a Gel-Filtration chromatography, there is a stationary phase and a mobile phase. The stationary phase has beads with pores. Small molecules enter the beads and descend through these beads' pores. On the other hand, large molecules do not enter the beads' pores, so they go down through the mobile phase faster than the small molecules. Since they do not have the obstacle of the pores, they descend between the beads more fluidly. As a result, the larger molecules elute first from the gel than the small molecules.

Chemical weathering erodes the land/basically sort of melts the land away due to the pollution in the rain.
Explanation:
Answer:
Chemical weathering changes the molecular structure of rocks and soil. ... Sometimes, chemical weathering dissolves large portions of limestone or other rock on the surface of the Earth to form a landscape called karst. In these areas, the surface rock is pockmarked with holes, sinkholes, and caves.
Identify the following particles as being charged or uncharged/neutral. If charged, indicate whether they are charged positively or negatively. (n = neutron, p = proton, e = electron)
*particle C
proton +20
electron -18
urgent ^^
Answer:
Particle A is negatively charged.
Particle B is neutral.
Particle C is positively charged.
Explanation:
Particle A is negatively charged because the number of electrons is more than number of protons so the particle gain negative charge. Particle A is neutral due to same number of proton and electron which cancels the effect of one another and become neutral whereas the Particle B is positively charged due presence of more number of protons as compared to number of electrons so the particle gain positive charge.
what three phases of the cell cycle are considered interphase
Answer:
The cell cycle has three phases that must occur before mitosis, or cell division, happens. These three phases are collectively known as interphase. They are G1, S, and G2. The G stands for gap and the S stands for synthesis.
Explanation:
The three phases of the cell cycle that are considered interphase include G1, S phase and G2.
The cell cycle can be divided into the interphase and mitotic (M) phases.The interphase can in turn be divided into a Growth G1 phase, synthesis (S) phase and Growth G2 phase.The synthesis of the genetic material (DNA) occurs in the S phase, whereas in G1 and G2 the cell synthesizes all materials required to enter into cell division.In conclusion, the three phases of the cell cycle that are considered interphase include G1, S phase and G2.

Another aspect of the competitive exclusion principle is that animals that compete within the same environment may eventually come to occupy their own NICHE. A niche is a way of life, and includes how the animal lives, what it eats, reproduction strategies and more. For example, a hawk and owl both eat the same kinds of food, but the owl hunts at night and the hawk during the day. How did your final ecosystem?
Answer:
Both hawk and owl share the same habitat or ecosystem.
Explanation:
According to competitive exclusion principle, two species can't coexist in the same environment if they occupy exactly the same niche but in the case of hawk and owl, it is possible because both have different times of eating habits. Hawks hunts at daytime while on the other hand, an owl hunts at night so both share the same habitat due to difference in their niche and they are present in the same ecosystem.

How are humans impacting biodiversity in ecosystems around the world? Provide two examples to support your claim.
Answer:
as humans population continues to grow, we're cutting down more trees and occupying more lands to suffice the need of citizens, therefore, decreasing the forest biodiversity. Our plastic bags, as well as wastes, are polluting the ocean and eradicating essential species that are required to sustain a balance ecosystem, therefore, decreasing the biodiversity of the ocean that are required to maintain a balance environment.
Human activities have affected in Biodiversity in the ecosystems negatively and such activities include : i) Indiscriminate hunting/fishing ii) Improper waste disposal
Humans in search of food ( meat ) engage in excessive/indiscriminate hunting of endangered species thereby reducing the Biodiversity of animal species present in the wildlife also excessive fishing activities affects the biodiversity of certain species of fishes in our oceans negatively.
When wastes are not properly disposed they degrade the environment and decrease the biodiversity of the ecosystems in the process. the burning of industrial wastes leads to the exposure of certain species to the negative effects of dangerous gases and liquids thereby making the ecosystems to become unbalanced.
Hence we can conclude that some of the human activities impacting biodiversity in ecosystems around the world include : Indiscriminate hunting/fishing and Improper waste disposal
