Explanation:
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.

In Wakanda, in a population in Hardy-Weinberg equilibrium, the frequency of the single recessive allele controlling vibranium assimilation, which affects superhuman abilities, is 0.2. What is the percentage of the population that is heterozygous for this allele
Answer:
32%
Explanation:
Hardy–Weinberg equilibrium is also known as Hardy–Weinberg law. The idea of Hardy–Weinberg equilibrium is about the frequency of alleles in a population. The frequency of an allele in the population will always remain the same in a population if that population is not influenced by any evolutionary consequences.
Hardy–Weinberg equilibrium binomial expression formula is p2+2pq+q2=1. Suppose the frequency of recessive allele = q.
and another normal allele is = p
Here Q = 0.2 so P will be 1- Q or 0.8
By Hardy–Weinberg equation p2+2pq+q2=1, Here 2pq denotes the frequency of recessive allele, so 2pq = 2 × 0.2 × 0.8 = 0.32, if converted into percentage it will be 32%.

Which of the following statements is not true?\
A. Water is essential for life.
B. Water stabilizes temperature.
C. Water is polar.
D. Water is the most abundant atom in Earth’s atmosphere.
E. Water and ice vary in density.
Answer:
D. Water is the most abundant atom in Earth’s atmosphere.
Explanation:
An atom can be defined as the smallest particle of an element (e.g., oxygen, hydrogen, etc). Water is a molecule (H2O) because its atoms are connected by molecular bonds (i.e., water is not an atom). Water is the most abundant molecule on the Earth's surface which covers more than 70 percent of the world's surface. A water molecule contains one oxygen (O) and two hydrogen (H2) atoms which are connected by covalent bonds. Water is also a compound known as a diatomic molecule, i.e., a molecule composed of two atoms of the same type.

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.

Given the following cross TtYyRr x TtyyRr (T = tall; t = short Y = yellow; y = green R = round; r = wrinkled), what proportion of offspring would be expected to be short plants with round, green seeds. Write your answer as a reduced fraction - e.g. 1/2 proportion is
Answer:
3/32 ttyyR-
Explanation:
Cross: Tall, Yellow, Rounded individuals with a tall, green, rounded individual
Parentals) TtYyRr x TtyyRr
Gametes) TYR, TyR, TYr, Tyr, tYR, tyR, tYr, tyr (Parent one)
TyR, TyR, Tyr, Tyr, tyR, tyR, tyr, tyr (Parent two)
We need to know what proportion of offspring is expected to be short plants with round, green seeds. So we need to identify the gametes for these traits. The genotypes are:
Shot → ttRound → RR or RrGreen → yy⇒ Parent one can provide gametes tyR and tyr
⇒ Parent two can provide gametes tyR and tyr
(1/8 tyR x 2/8 tyR) + (1/8 tyR x 2/8 tyr) + (1/8 tyr x 2/8 tyR) =
2/64 ttyyRR + 2/64 ttyyRr + 2/64 ttyyRr =
1/32 ttyyRR + 2/32 ttyyRr =
3/32 ttyyR-
The branch of science which deals with the gene and inheritance is called biology.

In the population of plant K, each plant has only red flowers or only white flowers. A farmer collected the seeds from plant K with red flowers to grow new plants. Explain why the new plants will have only red flowers
Answer:
nose
Explanation:
nosenosenosenosenosenosenosenosenosenosenose
The new plants will have only red flowers because the trait for red flowers is determined by a dominant gene, and all the plants in population K have the same homozygous genotype for the flower color.
In genetics, the flower color trait in population K is determined by genes present in the plants' DNA. There are two alleles, or gene variants, for the flower color: one for red flowers (let's call it R) and one for white flowers (let's call it r). The gene for red flowers (R) is dominant, meaning that even if only one copy of the gene is present in an individual's genotype (heterozygous), it will produce the red flower phenotype. On the other hand, the gene for white flowers (r) is recessive, which means it will only produce the white flower phenotype if two copies are present in the genotype (homozygous recessive).
In population K, all the plants have only red flowers, indicating that they must have the genotype RR. Since all the plants are homozygous for the dominant red flower gene (RR), when they reproduce, they can only pass on the dominant allele R to their offspring. As a result, all the new plants that grow from the seeds collected from these plants will also have the genotype RR and, therefore, express the red flower phenotype.
Since there are no plants in population K with the genotype rr (homozygous recessive), which is necessary for white flowers, there is no chance of white-flowered plants appearing in the new generation. Thus, the new plants will have only red flowers due to the uniformity of the homozygous dominant genotype in the original population.
