If a new beetle was found you would know if it was a invasive species depending on where you found it. A invasive species may be found on a eaten plant or a eaten tree. Although you would have to find a few to be sure.

Anton [14]

Answer:

The mismatch is on the statement that says "Bacillus anthracis produces antioxidants to combat lysosomes."

Explanation:

A. Bacillus anthracis produces antioxidants to combat lysosomes.

This is incorrect. Bacillus anthracis is a bacterium that forms aerobic spores, whose structures contain the genetic material of the bacteria and that resist long periods without water or nutrients, in conditions of extreme heat or cold. Bacillus anthracis is found in some forms, one of this, is the cutaneous anthrax. Cutaneous anthrax is a skin infection caused by direct contact with the bacterium.

B. Coxiella burnetii produces an endospore-like structure.

Coxiella burnetti is a bacterial zoonosis and produces structures similar to endospores, which are cells or forms of resistance that develop certain bacilli against heat, desiccation, radiation and chemical influences.

C. Trypanosoma cruzi cloaks itself in host proteins to avoid immune recognition.

Trypanosoma cruzi is characterized by being a parasite with great antigenic variability. In the host infected with Trypanosoma cruzi, the membrane protein called cruzipain, is a response used in favor of the parasite. The humoral response to the cruzipain antigen, the largest antigen of Trypanosoma cruzi, is implicated in the pathogenesis of experimental Chagas disease.

D. Borrelia burgdorferi changes its surface antigens to avoid immune recognition

Borrelia burgdorferi is a bacterium that produces Lyme disease, once infected, the bacterium recombines by altering the antigens of its membrane, preventing immune recognition.

If two women have identical alleles of the suspected 20 height-associated genes, why might one of those women be 5 feet 5 inches
Fofino [41]
Since there are 20 heigh-associated genes and only two of the alleles are identical to both of them, the other genes could have different effects on the development of their bone and muscle cells which can result to the two women having different heights.

xz_007 [3.2K]

The right answer is B) crossing over.

Crossing-over is a genetic phenomenon that occurs during meiosis and contributes to genetic mixing during reproduction (genetic recombination).

At the end of prophase 1 (early metaphase 1) of meiosis, the homologous chromosomes (i.e. of the same pair) overlap thus forming characteristic features called "chromatid tetrads" and exchange fragments of chromatids. The result is the intra-chromosomal mixing of the alleles
