Lactobacillus in yogurt, some Escherichia coli in the intestines of humans and animals, and Rhizobium that fixes atmosphere nitrogen are all considered beneficial bacteria. Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a True b False
Answer: a. True.
Explanation:
Lactobacillus is a genus of gram-positive, facultative or microaerophilic bacteria that produce lactic acid. They are normally found in different parts of the body such as the mouth, digestive tract and vagina. Lactobacilli usually do not cause disease, although they can cause dental caries. Some lactobacilli have a homofermentative metabolism, that is, they produce lactic acid from sugars, which makes their environment acidic and inhibits the growth of pathogenic bacteria. Some species of Lactobacillus are used in the industry for the production of yogurt, cheese and other fermented foods.
Escherichia coli is a bacterium that is part of the microbiota of the gastrointestinal tract of various animals. It is a gram-negative bacillus, facultative anaerobe, and the most abundant commensal of the microbiota of the gastrointestinal tract where, together with other microorganisms, it is essential for the correct functioning of the digestive process. It also participates in the production of B and K vitamins.
Rhizobium is a genus of gram-negative soil bacteria that fix atmospheric nitrogen and live in symbiosis with certain plants (such as leguminous plants) in their roots, after a process of infection induced by the plant itself through the secretion of lectin, to which they provide the nitrogen necessary for the plant to live and which in return gives it shelter. Fixation is the combination of molecular nitrogen (N2) with hydrogen or oxygen to give ammonium or oxides that are incorporated into the biosphere. Molecular nitrogen, which is the major component of the atmosphere, is inert and not directly usable by most living things. Therefore, it involves the incorporation of a significant amount of nitrogen into the biosphere.
Therefore, all three are considered beneficial.
explain the factors that contribute to the success of class insecta.
Answer:
It is believed that insects are so successful because they have a protective shell or exoskeleton, they are small, and they can fly. Their small size and ability to fly permits escape from enemies and dispersal to new environments. ... In addition, insects can produce large numbers of offspring relatively quickly.
There are a number of important aspects that contribute to the success of the Class Insecta, which includes insects. The factors are their size, thin exoskeleton, reproduction, etc.
First off, because of their modest size and effective body composition, they may occupy a variety of environments and fill a variety of biological niches.
Insects have a thin exoskeleton that allows for flexibility and motion as well as protection and support.
Because of their diminutive size, they can access a variety of microhabitats, cracks, and supplies that larger species cannot.
In addition, insects have remarkable methods and capacities for reproduction. The majority of insects reproduce quickly and give birth to numerous young.
They use a variety of reproductive techniques, such as internal fertilisation and complex courtship rituals.
Thus, the small size, effective body structure, variety of reproductive techniques, flexibility, and resilience of Class Insecta are factors in their success.
Thus, these elements have made it possible for insects to survive in a variety of habitats, use a range of resources, and play essential roles in ecosystems as pollinators, decomposers, predators, and prey.

Examine the mechanism of carbonic anhydrase. If the Zn2 were removed from the active site, and replaced with either Cu , Cd2 , or Fe3 would you expect the enzyme to still be functional
Answer: No
Explanation:
Carbonic anhydrase (CA; carbonate hydro-lyase) is a zinc-containing enzyme that catalyzes the reversible hydration of carbon dioxide: CO2+ H2O<-->HCO3(-)+H+. The enzyme is the target for drugs, such as acetazolamide, methazolamide, and dichlorphenamide, for the treatment of glaucoma.
The zinc ion is located in a cone-shaped cavity and coordinated to three histidyl residues and a solvent molecule. Inhibitors bind at or near the metal center guided by a hydrogen-bonded system comprising Glu-106 and Thr-199. The catalytic mechanism of CA II has been studied in particular detail. It involves an attack of zinc-bound OH- on a CO2 molecule loosely bound in a hydrophobic pocket. The resulting zinc-coordinated HCO3- ion is displaced from the metal ion by H2O. The rate-limiting step is an intramolecular proton transfer from the zinc-bound water molecule to His-64, which serves as a proton shuttle between the metal center and buffer molecules in the reaction medium.

Immune responses can be either innate (nonspecific) or adaptive (specific). Suppose a person comes into contact with bacteria that cause a disease that the person has experienced previously. The production of antibodies to fight off the infection is considered an _____ response, while the development of a fever to inhibit bacterial growth is considered an _____ response. (the possible answers to the blanks are "Adaptive" and "Innate")
Answer:
adaptive; innate
Explanation:
The adaptive immune system refers to a specific type of immunity which is found only in vertebrates. Adaptive immunity is defined by the presence of specialized immune cells (i.e., lymphocytes such as T and B cells). The B cells produce molecules known as antibodies which destroy specific pathogenic microorganisms (e.g., bacteria, viruses) and thus prevent diseases in the future. On the other hand, the innate immune system is the first (and evolutionary more ancient) defense line against pathogenic infections or tissue injury. Innate immunity includes, among others, physical barriers, anatomical barriers, phagocytic enzymes (i.e., lysozymes), phagocytic cells (i.e., macrophages), inflammation, etc. Inflammation is defined as an innate immune response composed of complex biological processes that protect the body by eliminating harmful microorganisms and intracellular danger signals, thereby regulating signaling pathways of many diseases.

The Nutrition Facts panel provides valuable nutrition information such as serving sizes, nutrient quantities, and Daily Values to assist individuals in making informed food choices. Use the Nutrition Facts panel from a container of cereal below to answer the following questions. Based on one serving, how many grams of total sugar do not come from an added sugar source?
Answer:
The right answer is "3 grams".
Explanation:
Yet another portion doesn't supply about 3 g of sugar from such an increased proportion.
That would be the reason why sugar has been biologically active throughout the cereal's static environment.All cereals that are given above 6 g of sugar for each serving are determined to be harmful as well as reacted by either a cereal that has very little sugar.do roots have guard cells and therefore stomata?

How is the small ribosomal unit positioned to allow for translation to start at the proper start codon?Choose one:
A. Shine-Dalgarno sequence
B. The start codon sequence is specifically attracted to the P site.
C. Initiation factors position the mRNA accordingly.
D. The small ribosomal subunit starts at the far 5' end of mRNA where the start codon is located.
Answer:
approximately 15 seconds
A. Shine-Dalgarno sequence
Explanation:
In Escherichia coli, it has been shown that the translation elongation rate is approximately 16 amino acids per ribosome per second (16 x 15 = 240). On the other hand, the Shine-Dalgarno sequence is a polypurine stretch of variable length present in prokaryotic cells and acts as a ribosomal binding site for the messenger RNA (mRNA). This sequence can base-pair to a complementary sequence known as the 'anti-Shine-Dalgarno sequence' at the 3' end of the bacterial 16S rRNA subunit and is required to initiate the process of translation by which a polypeptide chain is synthesized. Generally, the Shine-Dalgarno sequence is located from 10 to 8 nucleotides upstream of the start codon (AUG codon). In E. coli, the Shine-Dalgarno sequence is AGGAGGU.
Two normal parents produce a child affected with the autosomal recessive disease homocysteinuria. They want to have 3 more children. You tell them the chance of 1 OR MORE affected among the next three children is:
Answer:
Zero
Explanation:
Because in a situation whereby both parents are carriers of an autosomal recessive condition there is a 1 in 4 chance of them having an affected child.
Hence, given that these two normal parents have already had one affected child with the autosomal recessive disease homocystinuria. There is ZERO chance of having an affected child in the next three kids they will be having.

Answer:
Heterogéneas.
Explanation:
Se denomina "heterogénea" a toda aquella cosa que, por sus características particulares, no puede ser asimilada a otras sino que posee una individualidad particular que impide dicha asimilación. Así, por ejemplo, una piedra y una canica son heterogéneas entre sí, en tanto no poseen las mismas características y por lo tanto son claramente diferenciables.
Give three reasons why you might have a situation in which bacterial colonies were found on the first section of a streak plate, but not on sections two and three.
Hi. You have not shown the sections this question refers to, nor have you provided more information about those sections. This makes it difficult for your question to be answered. However, I will try to help you as best I can.
Generally speaking, we can consider that there was no growth of bacterial colonies in sections 2 and 3, because, for some reason, the bacteria was not inoculated in sections 2 and 3. What could also have happened, is that the bacteria in the sections 2 and 3 were eliminated, but the bacteria from section 1 managed to survive and form colonies.
Another possibility is that after inoculating the bacteria in section 1, you didn't handle the bacteria correctly in the other sections, leaving that bacteria to dry out and die.
Finally, the culture media in sections 2 and 3 could be inappropriate for bacteria to develop and form colonies.
