He did this by experiment with anthrax. Using a microscope, Koch analysed the blood of cows that had failed of anthrax. He marked rod-shaped bacteria and supposed they caused anthrax.

<h3>What does anthrax do to a human?</h3>

Anthrax induces skin, lung, and bowel disease and can be fatal. Anthrax is analysed using bacterial cultures from infected tissues.

There are 04 kinds of anthrax: cutaneous, inhalation, gastrointestinal, and injection.

Anthrax is cured by antibiotics.

Thus,  He kept rod-shaped bacteria and supposed they caused anthrax.

What would have to be done to a plant oil to transform it to a trans fat in simple molecule terms?
ivann1987 [24]
<span>In order to understand trans fat, you must understand the prefix. Trans and cis are prefixes that mean opposite and same side, just like transgender people identify with a gender that is not in line with their biological sex, and cisgender people identify with their biological gender. Cis fat describes the fatty acids attached to the glycerol in triglycerides. Cis fats have hydrogen attached to the carbon chain just like trans fats, but at one, two, or more places on the chain, two hydrogen atoms attached on the same side, and the fatty acid chain gets bent, making the collection of fats less dense and therefore healthier for you and I. Trans fats have hydrogen atoms on alternating sides all the way down the chain, making them denser and solid at room temperature. In order to turn a plant oil (cis fat) into trans fat, the cis fat has to be blasted with hydrogen in order to turn the fatty acid chains from cis to trans. This adds more energy to the fats while also making them denser, which turns olive oil into a butter-like substance.</span><span />

What is the genotype of a male with red-green color blindness?
balandron [24]

Answer:

The genotype of male with red-green color blindness is XY, X chromosome possessing recessive allele of gene responsible for differentiating red-green color.

Explanation:

Color blindness is sex-linked trait and its inheritance follows criss-cross pattern. Dominant gene of allelomorpihc pair enables a person to differentiate between red and green color.

The genotype of male and female are different for the pair of sex chromosomes. Male is hetero-zygous (XY) and female is homo-zygous (XX). The gene controlling this trait is present on X chromosome.

Hope this helps (:

Each transfer RNA requires at least four specific recognition sites that must be inherent in its tertiary structure in order for
Jet001 [13]

Answer: The options are not included.

But the sites are;

Interaction with ribosomes.

Interaction with aminoacyl tRNA

synthase.

Attachment of the specific Amino acid.

Interaction with codon.

Explanation:

Transfer RNA is a type of RNA that help to translate messenger RNA sequence into protein. Each tRNA have two major areas; the anticodon and region for attaching specific Amino acids.

tRNAs function at specific sites in the ribosomes during mRNA deciding.

The four specific recognition sites of trna that must be inherent in it's tertiary structures in order for it to carry out it's role are;.

Interaction with ribosomes.

Interaction with aminoacyl tRNA synthase.

Attachment of specific Amino acid.

Interaction with codon.

You are operating a powerboat at night. Your red sidelight must be visible to boats approaching from which direction(s)?
Degger [83]
I believe the answer is head-on and port (left). The side lights are usually visible to vessels approaching from the front or the side. The red light usually indicates a vessel's port (left) side while the green light indicates a vessel's starboard (right) side. These lights ensure that there is safety at night as the vessels navigate.
