During division, the code for the protein cytochrome-C had the code for proline
changed to the code for leucine. This type of change in the genetic material is
known as a -

A. redundant mutation

B. frameshift mutation

C. point mutation

D. chromosomal mutation

Answers

Answer:

Point Mutation

Explanation:

The type of change described, where the code for proline is changed to the code for leucine during division, is known as a point mutation. The correct option is C.

A point mutation refers to a change in a single nucleotide base of the genetic material (DNA or RNA).

In this case, the change occurred at a specific position in the genetic code, resulting in the substitution of one nucleotide for another. This substitution led to a different amino acid being incorporated into the protein sequence.

Thus, based on the description provided, the correct answer is C. point mutation, as it involves the specific substitution of one nucleotide for another in the genetic code.

An animal welfare group is curious if the effects of selectively breeding goats to produce more milk is bad for the goats. What would be the BEST question that the welfare group could ask to determine the effects of selectively breeding the goats?

A.
What does the milk of the selectively bred goats taste like?

B.
What is the diet the goats are fed in order to produce milk?

C.
Can you make more money by producing the goats with the desired traits?

D.
Are there negative traits in the selected traits on the goat population?

PLZ HELP .what are 3 pieces of evidence that abiogenesis is responsible for the origin of life?

Answers

Abiogenesis proposes that the first life-forms generated were very simple and through a gradual process became increasingly complex. Biogenesis, in which life is derived from the reproduction of other life, was presumably preceded by abiogenesis, which became impossible once Earth’s atmosphere assumed its present composition. Modern abiogenesis hypotheses are based largely on the same principles as the Oparin-Haldane theory and the Miller-Urey experiment. There are, however, subtle differences between the several models that have been set forth to explain the progression from abiogenic molecule to living organism, and explanations differ as to whether complex organic molecules first became self-replicating entities lacking metabolic functions or first became metabolizing protocells that then developed the ability to self-replicate.

The habitat for abiogenesis has also been debated. While some evidence suggests that life may have originated from nonlife in hydrothermal vents on the ocean floor, it is possible that abiogenesis occurred elsewhere, such as deep below Earth’s surface, where newly arisen protocells could have subsisted on methane or hydrogen, or even on ocean shores, where proteinoids may have emerged from the reaction of amino acids with heat and then entered the water as cell-like protein droplets.

What would happen if you did an experiment in which the iodine solution was placed in a baggie, and the starch solution was in the beaker?

Answers

The iodine would move out of the baggie and the starch would change color

If the iodine solution was placed in a baggie and the starch solution was in the beaker, and the baggie was then submerged in the beaker, a specific chemical reaction called the iodine-starch reaction would occur.

The iodine-starch reaction is a well-known test used to detect the presence of starch in a solution. Normally, when iodine solution (iodine dissolved in water) comes into contact with starch, it forms a dark blue or black color complex.

This reaction is due to the formation of an inclusion complex between the iodine molecules and the helical structure of starch.

Describe an example of fermentation that occurs in beneficial bacterial cells within animals and explain why it is important.

Answers

Fermentation is an anaerobic process in which energy can be released from glucose even though oxygen is not available. Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals. In these situations, your working muscles generate ATP anaerobically (i.e., without oxygen) using a process called fermentation. Fermentation is beneficial in that it can generate ATP quickly for working muscle cells when oxygen is scarce. Fermentation helps break down nutrients in food, making them easier to digest than their unfermented counterparts. For example, lactose — the natural sugar in milk — is broken down during fermentation into simpler sugars — glucose and galactose ( 20 ).

Microbial fermentation takes place within the gastrointestinal tract of the majority of the animals by the bacterial cells, this helps in the process of digestion and in the synthesis of certain essential components like vitamins.

• The enzymatic decomposition and the usage of food components, mainly carbohydrates by the help of microbes like bacteria anaerobically is termed microbial fermentation.

• Within the gastrointestinal tract of the majority of animals, the process of fermentation takes place, however, the intensity of fermentation depends on the quantity of bacterial cells present, which is usually greatest in the intestine.

• The process of fermentation within the intestine by bacteria primarily helps in the process of metabolism and digestion of carbohydrates that does not get digested in the small intestine like residual starch and cellulose.

• Apart from this, microbial fermentation also helps in the production of vitamin K and some B vitamins.

Thus, microbial fermentation within the intestine of the majority of the animals performs essential functions like digestion and production of vitamins.
