Answer:
A. The d. extensor retinacula are the broad ligamentous sheets that contain the tendons of the anterior compartment muscles.
B. Inversion and dorsiflexion of the foot is achieved by contracting the a. tibialis anterior muscle.
C. The b. extensor hallucis longus muscle has a skeletal attachment on the distal phalanx of the first digit.
D. The c. lateral condyle of the tibia is a skeletal attachment site of the tibialis anterior muscle.
Explanation:
The two extra options are the f. extensor digitorum longus and the e. medial epicondyle. The first one is a muscle in the anterior part of the legs that originates in the anterior lateral condyle of the tibia and the anterior part of the fibula. Its insertion is in the four phalanges of the 2, 3, 4, and 5 digits. The first digit has the insertion of the extensor hallucis longus. The extensor digitorum longus and the b. extensor hallucis longus has the same function, the extension of the toes, the extensor hallucis longus only extends the first digit, and the extensor digitorum longus extends the other four digits simultaneously.
The second extra option, the medial epicondyle, is in the femur. It is a prominence in the distal part of this bone. The tibial collateral ligament and the Magnus muscle insert in this part of the femur.
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.
The average amino acid length of proteins in Escherichia coli is 235. Therefore, according to the video, the elongation time for an average E. coli protein would be about _______seconds.
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.

In a changing environment, which of the following would be beneficial for the survival of a species?
O offspring with a variety of phenotypes
O offspring with little variation in phenotype
O offspring that closely resemble their parents
O offspring that are adapted to a specific environment
The last one
Explanation:
Offspring that are adapted to a specific environment is the beneficial for the survival of a species.
What is species?A species is an organism's fundamental unit of classification, taxonomic rank, and biodiversity. The biggest group of organisms in which any two individuals of the right sexes or mating types can conceive a fertile offspring, usually by sexual reproduction, is referred to as a species.
A species can also be identified by its karyotype, DNA sequence, anatomy, behavior, or ecological niche. In addition, since fossil reproduction cannot be studied, paleontologists use the chronospecies idea.
There are between 8 and 8.7 million different species of eukaryotes, according to the most recent accurate estimate.
All species are given a two-part name, or "binomial," with the exception of viruses.
Therefore, Offspring that are adapted to a specific environment is the beneficial for the survival of a species.

Algal blooms, and the rapid proliferation of photosynthetic plankton can ultimately end up depleting all the oxygen from a body of water
Answer:
True
Explanation:
The proliferation of phytoplankton (microalgae) may decrease the visibility which causes oxygen (O2) depletion because they consume important amounts of O2 during the night and cloudy days. An algal bloom refers to the sudden increase in the population of algae in water bodies. These algae consume O2 and block the sunlight from underwater plants. As the algae die and decompose, O2 concentration in the water decreases, and, in consequence, most aquatic life that depends on oxygen dies.

Who do we balance a chemical equation
Answer:
We have to balance chemical equations because you need to satisfy the law of conservation of matter. That states that matter cannot be produced or destroyed in a closed system. The law of conservation of mass governs the balancing of a chemical equation.
Answer:
I think you meant how?
Explanation:
but always you balance a chemical equation by looking at how many atoms you have for each element. For example we have the chemical equation Na + Cl2----> NaCl
so there's 1 Na atom
there's 2 Cl atoms
and for the product side
there's 1 Na atom
there's 1 Cl atom
TO BALANCE THIS you have to make the reactants side equals the product side by ADDING COEFFICIENTS.
so it would be 2Na + Cl2 ---> 2NaCl

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.
