You eat a bowl of beans as part of vour dinner. As vou digest the beans, the proteins that are present get broken down to their

component amino acids. As your body destroys the macromolecules that were present in the beans, is the energy present in those molecules destroyed?
A. Yes. By breaking down these macromolecules, some of the energy they contained is destroyed.
B. No. While the vast majority of the energy contained in these macromolecules is converted to heat, it is not actually destroyed.
C. No. The energy contained within these macromolecules is converted into other forms of chemical energy and kinetic energy, though some is lost as heat.
D. No. Breaking down molecules does not lead to the release of energy.

Answer:

Option C, No. The energy contained within these macromolecules is converted into other forms of chemical energy and kinetic energy, though some is lost as heat.

Explanation:

Breaking down of large molecules in to smaller molecules does not signify breaking down of energy stored in it and hence losing all the stored energy.  

Breaking down of large molecule is necessary to convert large molecules into small easily digestible molecules so that the food energy stored in them can be  stored  in some other form specifically chemical energy and can be used at later stages. However, in the process of conversion of large molecules into small molecules , a certain amount of heat energy is used.

Hence, option C is correct

How does scientific names impact classification
kicyunya [14]
      That is an oddly phrased question.  The scientific names we use now cam from the system of classification that spawned the way we still classify organisms today, started by Carolus Linnaeus. So the better question might be, how did classification impact scientific names?
      Of course, in all of the charges that go on in taxonomy, the answer o your question might be that, as the systems and ranks became more complicated, the additions had been made farther up the hierarchy, as to not affect the genus and species levels so much, as those levels are what we use for scientific names.

If a heterozygous plant with green seeds self-fertilizes, what is the probability that 6 seeds in a single pod of the progeny pl
nalin [4]

Here is the complete question

The seeds in bush bean pods are each the product of an independent fertilization event. Green seed color is dominant to white seed color in bush beans.

If a heterozygous plant with green seeds self-fertilizes, what is the probability that 6 seeds in a single pod of the progeny plant will consist of:

A) 4 green and 2 white seeds?

B) all white seeds?

C) at least 5 white seeds?

Answer:

A) 0.3

B) 0.0002

C) 0.001

Explanation:

Let the allele for Green plant be = P

Let the allele for white plant be =  p

Let the heterozygous plant be Pp, if self fertilization occurs we have:

                   P                    p

P                 PP                 Pp                                                              

                                                           

p                 Pp                 pp                  

From the punnet square above, we have the following  cross;

PP, Pp, Pp, pp

Since P is dominant to p; we have a phenotypic ratio of 3:1 between the dominant phenotype ( PP, Pp, Pp ) and recessive phenotype ( pp )

NOW, the probability for the green plant(i.e PP or Pp) will be: Pr(G)=\frac{3}{4}

the probability for the white plant (pp) will be: Pr (W)= \frac{1}{4}

A)

what is the probability that 6 seeds in a single pod of the progeny plant will consist of 4 green and 2 white seeds?

Pr(4G2W) = (\frac{3}{4})*(\frac{3}{4})*(\frac{3}{4})*(\frac{3}{4})*(\frac{1}{4})*(\frac{1}{4})

The probability includes the use of permutation:

Permutation(P)=\frac{6!}{(4!*2!)} * (\frac{3}{4})*(\frac{3}{4})*(\frac{3}{4})*(\frac{3}{4})*(\frac{1}{4})*(\frac{1}{4})

= 15*(\frac{3}{4})*(\frac{3}{4})*(\frac{3}{4})*(\frac{3}{4})*(\frac{1}{4})*(\frac{1}{4})

= 0.2966

≅ 0.3

B)

What is the probability that 6 seeds in a single pod of the progeny plant will consist of all white seeds?

Since probability for white seed = \frac{1}{4}

The probability that 6 seeds will consist of all white seeds will be = (\frac{1}{4})^6

=  2.44 × 10⁻⁴

= 0.000244

≅ 0.0002

C)

What is the probability that 6 seeds in a single pod of the progeny plant will consist of at least 5 white seeds?

For at least 5 white seeds, the probability will consist of  5 white seeds and 6 white seeds.

For 5 white seeds; we have:

5 White  and 1 Green  Since there are 6 permutations.

The probability For 5 white seeds will therefore be :

Pr(5 seeds)=(\frac{1}{4})^5*(\frac{3}{4})^1 *6

= 7.32 × 10⁻⁴

= 0.000732

For 6 white seeds; we have:

Only one permutation for 6 whites since there will no be any presence of any green seed.

Pr(6seeds)=(\frac{1}{4})^6

= 2.44 × 10⁻⁴

= 0.000244

∴

The total probability for at least 5 white seeds =  0.000732 + 0.000244

= 9.76  × 10⁻⁴

= 0.000976

≅ 0.001

Select the reasons that farmers typically only specialize in one breed.
Bogdan [553]
Answer options are
✅Homogeneous housing -
✅Familiarity with the breed
✅Business efficiency
✅Standardized food supply
Lack of training ❌
Time demands❌
✅Personal preference

Reasons
I’m using beef cattle to determine these answers.

I chose the ✅ answers because of the following
✅ Homogenous housing. If you live in extremely cold or hot climates, you want livestock that can withstand cold temperatures for housing reasons. Hereford and Angus are hearty and survive cold temps, Brahman are warm weather cattle.

✅Being familiar with the breed makes raising that breed easier. For example if you know Angus beef cattle and not Chalais dairy cows, you won’t know the Chalais’s unique characteristics.
✅Business efficiency - having one brand or one breed in this instance will save in time, management, food supply, medicines, etc. Different breeds will require different nutrients and feed, different housing requirements, for example.
✅ Standardized food supply. Again, different breeds require different nutrients. Having just one breed will keep food supply simple.
✅ personal preference. Although this might not be a sound business practice, people tend to stick with things they know and like.
