The figure describes what kind of evolution method?

A. Natural selection

B. Gene flow

C. Genetic Drift

D. non-random mating

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.

Offspring that are adapted to a specific environment is the beneficial for the survival of a 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.

The correct answer is - B. false.

Explanation:

A section or segment of the DNA that contains the genes for the proteins needed for a  specific metabolic pathway is called an operon. Gene regulation on other hand is the process of an organism to control which genes are transcribed.

Gene regulation is the ability of turning the genes on or off for transcription. It is regulated by various ways such as chemically modifying genes and using regulatory proteins.

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.

Fat cells burn energy quickly when other food source is available, so being expandable would help with the rapid burn.

The relationship between the expandability of fat cells and a fat cell's function is ; ( A )  Fat cells store energy for the body to use later, so being expandable would help with storage.

Fat cells specialized for the storage of energy in human body is the Adipose tissue which can expand between 60 to 70% of the weight of the human body in response to changes in the energy balance of the body.

Adipose tissues store energy in form of triglycerides and in order to store more energy for later use the Adipose would need to be expandable to accommodate the required amount of energy.

Hence we can conclude that the relationship between the expandability of fat cells and a fat cells' function is Fat cells store energy for the body to use later, so being expandable would help with storage.

The correct terms or tissues are :

mesenchyme

chondrocytes

fibrocartilage

stratified epithelia

reticular connective tissue

Explanation:

1. Mesenchyme is comprised of loose cells embedded in a mesh of proteins and fluid that makes the middle portion of the unspecialized mesoderm from which cartilage, bone, and blood develop.

2. The mature cells that live in cartilage and maintain the matrix around them are chondrocytes.

3. Fibrocartilage is a type of cartilage with a net of collagen fibers to help resist compression and tension.

4. Any tissues that exist in layers and form linings or coverings fall into the category of stratified epithelia.

5.. Reticular connective tissue is the type of connective tissue that is a supportive structural network fibre to support other cells.

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.

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.

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.
