Bacteria such as E. coli and Salmonella produce invasins that bind host cells, thus causing the cells to_____________.

Answer: Option A.

Invasins cause the cell to engulf bacteria.

Explanation:

Invasins is an enzyme or protein that allow pathogens to penetrate into the host cells. Inavasins allow Salmonella to gain entry into the host cells and bind it to it thereby engulfing the bacteria during the stage of infection. Salmonella and E.coli produce invasins enzymesso as to penetrate the host cells and enqulf the bacteria.

Answer:

A) Engulf the bacteria.

Explanation:

Invasins are basically enzymes (protiens) which act to damage the host cells locally. As E.Coli and Salmonella are the invasive bacteria , they need to invade the body cells in order to causes infection . It is involved in pathogenesis.  So as the enter the body they release invasins ,bind to host cells and cause them to engulf the bacteria which is then carried to the desired location and cause disease.

Hence a) Engulf the bacteria is the right option

Saccharomyces cerevisiae is a diploid yeast species that can reproduce either sexually or asexually. An experiment was performed
Savatey [412]

Answer:

D. The first division will reduce the number of chromosomes by half for each daughter cell, and the second division will move single chromatids to each daughter cell.

Explanation:

Gametes are formed by meiosis in diploid gamete mother cells. During gamete formation, the gamete mother cell in the yeast would undergo meiosis I. During first division (meiosis-I), the process of crossing over during prophase-I creates genetic variations and movement of homologous chromosomes to the opposite poles during anaphase-I reduces the chromosome number to half in each daughter cell.

Two daughter cells are formed by the end of meiosis-I each of which enters meiosis-II. Splitting of centromere and separation of sister chromatids during anaphase-II of meiosis-II results in the movement of single chromatids to the opposite poles of the cells.

The muscles of a recently deceased human can remain in a contracted state, termed rigor mortis, for several hours, due to the la
forsale [732]

Option A is correct. These ions then have interaction with actin and myosin filaments to purpose muscle contraction. The muscle groups stay in the shriveled state until adenosine triphosphate (ATP) binds to myosin, releasing the myosin and actin filaments from one another.

<h3>How long after a individual dies does rigor mortis set in?</h3>

Rigor mortis appears approximately two hours after dying in the muscle groups of the face, progresses to the limbs over the subsequent few hours, finishing between 6 to eight hours after death. [10] Rigor mortis then stays for some other 12 hours (till 24 hours after death) and then disappears.

<h3>Why does a body go into rigor mortis stiffen within 36 hours of death?</h3>

Rigor mortis is the 1/3 stage in which the muscle mass harden and become stiff, prompted with the aid of the lack of adenosine triphosphate (ATP), which gives electricity to the muscles. Rigor mortis is a extensive tool to any dying examination because it can narrow down the timeframe of death.

Leni [432]

Answer: D.)Biotic and Abiotic factors

Explanation: <em><u>The living things in an ecosystem are called biotic factors. Living things include plants, animals, bacteria, fungi and more. The non living parts of an ecosystem are called abiotic factors. In an ecosystem some abiotic factors are sunlight, temperature atmospheric gases water and soil. These would not limit pop growth as much as predation and disease. </u></em>
