Selective breeding.

Find a cow that produces lots of milk because its in its genes. Then find another cow with the same gene that would produce lots of milk also.

Then you should breed the two cows together ultimately producing a cow that produces lots of milk.

Of the following lists of electron transport compounds, which one lists them in order from the one containing electrons with the
notsponge [240]

Answer:

B) FADH2 -- FMN of Complex I -- Fe-S of Complex II -- Q -- Fe-S of Complex III -- Cyt c -- Cyt a of Complex IV -- O2

Explanation:

FADH2 and NADH give their high energy electrons to the terminal electron acceptor molecular oxygen via an electron transport chain. As the electrons move through electron carriers of the electron transport chain, they lose their free energy. Part of the free energy of the electrons is used to pump the protons from the matrix into the intermembrane space. Therefore, part of the energy of electrons is temporarily stored in the form of a proton concentration gradient.

NADH gives its electrons to FMN of complex I while FADH2 gives its electrons to the Fe-S center of complex II. Both the complexes are oxidized by coenzyme (Q) which in turn reduces Fe-S centers of complex III. Cyt c of complex IV obtains electrons from complex III and passes them to CuA center, to heme "a" to heme "a3-CuB center" and finally to the molecular oxygen.

So, the compounds arranged with respect to the energy content of electrons in descending order are as follows: FADH2 -- FMN of Complex I -- Fe-S of Complex II -- Q -- Fe-S of Complex III -- Cyt c -- Cyt a of Complex IV -- O2.

The first step leading to angiotensin II production is the secretion of what by the kidneys? Multiple Choice Calcitriol Angioten
Pachacha [2.7K]

Answer:

The correct answer is "Renin".

Explanation:

The secretion of the enzyme renin by the kidney is one mechanism used by the kidneys for blood pressure regulation. The secretion of renin is the first step leading to angiotensin II production, in what is known as the renin–angiotensin system (RAS). Renin catalyzes the conversion of  angiotensinogen to angiotensin I, which is subsequently converted to angiotensin II by the angiotensin-converting enzyme (ACE).

While most bacteria are eliminated by antibiotics, some can possess mutations that are resistant to antibiotics, leading to more
Papessa [141]

Answer:

The trait must make the individual more fit to survive. True

Explanation:

Darwin proposed that genetic variations are present in natural populations. Some genetic traits become beneficial under the changed environmental conditions. The organisms with these genetic traits are able to survive and reproduce better than the organisms that lack them. This results in an increased proportion of the beneficial genetic traits in the population over generations as the individuals having those traits reproduce more.

The presence of antibiotic resistance is a beneficial genetic trait that allows bacteria to survive in the presence of antibiotics. Natural selection favors the bacterial having antibiotic resistance and increases their proportions in the population over generations.

Which term applies to the biological aspect of a woodchuck living in underground burrows, eating plant food, and feeding often i
Fantom [35]
"C. Ecosystem"

An ecosystem is described by the interaction between living organisms in a given area, interacting with others, and non-living aspects of the environment where they are in. By considering the living place of a woodchuck, what they eat, and where they feed, we are talking about an ecosystem.
