Over a period of several years, a large hospital kept track of the number of births of babies displaying the trait achondroplasia. Achondroplasia is a very rare autosomal dominant condition resulting in dwarfism with abnormal body proportions. After 120,000 births, it was noted that there had been 27 babies born with achondroplasia. One physician was interested in determining how many of these dwarf babies result from new mutations and whether the apparent mutation rate in his area was higher than normal. He looked up the families of the 27 dwarf births and discovered that 4 of the dwarf babies had a dwarf parent. What is the apparent mutation rate of the achondroplasia gene in this population? Is it unusually high or low?
Clamworms and earthworms both belong to phylum Annelida. Curiously, earthworms have a thin cuticle outside of their epidermis and clamworms do not. Considering the relationship between an organism's form/function and its environment, which of the following provides the MOST logical explanation for this difference?a. The cuticle maintains salt balance in a marine environment.b. The cuticle provides protection against predators.c. The cuticle prevents water loss in a terrestrial environment.d. The cuticle allows for improved gas exchange.

Mycoplasma A. lack peptidoglycan.B. are the smallest free-living organisms.C. have sterols in their membranes.D. are killed by penicillin.E. lack peptidoglycan, are the smallest free-living organisms AND have sterols in their membranes.

Answers

Answer:

E. lack peptidoglycan, are the smallest free-living organisms AND have sterols in their membranes.

Explanation:

Mycoplasmas are also called pleuropneumonia-like organisms (PPLO) are the smallest free-living, prokaryotic organisms. They do not have a cell wall and is bounded by a plasma membrane which contains sterol.

Since cell wall is absent in them, they lack peptidoglycan. These are present in animals, plants, insects, soil and sewage. They grow better in the aerobic environment but can also live as facultative anaerobes.  

Mycoplasma cause infection, affects cell metabolism, gene expression.

The scientist anneals a mutant oligonucleotide to the original M13 DNA. Then DNA polymerase replicates the M13 DNA. After DNA synthesis, the scientist adds a restriction enzyme, EcoRI, that recognizes the DNA sequence 5′−GAATTC−3′5′−GAATTC−3′ and cuts after the guanosine nucleotide. Following the restriction digest, the scientist adds exonuclease III for a short period of time. Another round of DNA polymerase‑catalyzed DNA synthesis completes the procedure. What is the nucleotide mixture required by the DNA polymerase reaction in this procedure?

Answers

Answer:

The mixture of nucleotides required for this procedure is called dNTPs.

Explanation:

When the polymerase is used in a PCR procedure, to replicate a molecule or DNA fragment, use a combination of nucleotides called dNTPs.

DNTPs are nothing less than DNA nucleotides, applied as reagents in a PCR solution, which provide the material necessary for the polymerase to replicate DNA, even outside a biological system.

The diagram shows a basic food chain. Which is the primary consumer? rabbit grass snake hawk

Answers

Answer: The correct answer is-

Rabbit.

Food chain describes a linear path of energy transfer (in the form of organic matter) between different organisms present within an ecosystem.

The different organisms in the food chain occupy specific positions called trophic levels ( such as producers, primary consumers, secondary consumers, tertiary consumers, decomposers).

Primary consumers ( second trophic level of food chain) are the organisms that consume producers ( which occupy the first trophic level) for obtaining energy.

They are generally herbivores as they are dependent on plants (autototrophic organisms that synthesize their own food through photosynthesis).

Rabbits eat grass, various plants, and vegetables ( such as carrot), therefore  it is a primary consumer.

the correct answer is rabbit

Identify structures found in fungi

Answers

Answer:

Histopathology uses tissue samples to identify fungal structures by microscopy. If fungi are suspected, the specimens are first colored with stains that highlight the fungal wall as Gomori methenamine silver (GMS) or periodic acid-Schiff (PAS). This method, although is an important tool for the microbiologist, has also several limitations.

Explanation:

Hopes this helps you. But it is probably 1,2, and 3. Or it can be all of them.

What is the phase that not all cells enter, but it is a phase where cells are not actively dividing
Keeping in mind the life cycle of bacteriophages, consider the following problem: During the reproductive cycle of a temperate bacteriophage, the viral DNA inserts into the bacterial chromosome where the resultant prophage behaves much like a Trojan horse. It can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. Several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. Insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. As stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?
