Answer:
The options include:
1. degrade rust into a usable form of iron
2. secrete proteases that degrade host factors such as hemin or hemoglobin in order to access the released iron
3.invade cells in order to access iron within degradative lysosomes
4.use adhesins to bind free iron within the host
5.secrete lactoferritin that binds iron at very low concentrations
The answer is
2. secrete proteases that degrade host factors such as hemin or hemoglobin in order to access the released iron.
Due to the abundance of the pathogenic bacteria in their host , they are able to secrete enzymes known as protease which acts on protein component of the blood called Hemoglobin. This subsequent enzymatic action results in the release of iron for their use.
Answer:
The solar system is host to two broad categories of planets. The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres. The gas and ice giants — Jupiter, Saturn, Uranus and Neptune — are outliers. They are much larger than the terrestrial planets, but their cores are small and icy. Most of their size is formed by a combination of gases that become denser and hotter as you get closer to the core. Scientists count eight planets overall. Pluto was reclassified as a dwarf planet in 2006.
Explanation:
Energy cannot endlessly cycle through living systems, because energy is ONLY PARTIALLY transferred.
Answer;
both positive and negative
Explanation;
-The elephant are keystone species, playing an important role in maintaining the biodiversity of the ecosystems in which they live. They may have both negative and positive interactions to the environment. For example, during the dry season, elephants use their tusks to dig for water, which has a positive impact to the surrounding.
-They clear large amounts of vegetation, which removes habitats for some organisms but makes the area inviting for other organisms. This has both positive and negative impact to the ecosystem.
