What is the difference between heterozygous and homozygous?

Chemistry
1 answer:
Yuri [45]4 years ago
5 0

we can differentiate a heterozygous individual from a homozygote by analyzing their alleles. If the alleles in the homologous chromosomes are the same, we say that it is a homozygote. If the alleles are different, the individual is heterozygous.

Activities that shows the nature and goals of anthropology,Sociology and Political Science​
frez [133]

To answer the question effectively, we will talk about the key words in the question.

ANTHROPOLOGY, SOCIOLOGY AND POLITICAL SCIENCE.

ANTHROPOLOGY; This is the study of human kinds in all times and places,it also entails humanistic study which includes our prehistoric origins and contemporary human diversity as well as topics like social change,globalization,human origin and the world history.

The activities that shows the nature and goals of anthropology includes;

- Looking at ones own culture in a more objective way like an outsider.

- Discovering the things that make people more different from one another.

- Producing new theories and knowledge about human home and their behaviors.

- Discovering/finding out what all people have in common.

There are four fields of anthropology; Linguistic anthropology, Biological anthropology, Archeology and cultural anthropology.

SOCIOLOGY; This is the scientific study of human civilization.

It is systemic and studies of groups and societies that people build

and the effect these have on their behavior.

Sociology greatly focuses on various social connections,

structures, organizations, processes and institutions.

The activities that show the goals and nature of sociology includes;

- Broadening our familiarity on facts about sociology.

- Critically studying the nature of humanity.

- Exposing our minds to the diverse perspectives on attaining the truth.

- Obtaining possible theories about the society.

- Understanding and appreciating that all things in the society are interdependent with each other.

Sociology brings together inputs that are composed of frequent forms and manners,they include; view points, consolidated values, attitudes and the norms of social institutions.

The different branches of sociology are; social psychology,social organisation, applied sociology, population studies, sociological theory and research,human ecology,social change.

POLITICAL SCIENCE; This is a discipline in academics that deals with the study of political processes, institutions, governments and behaviors of people.

It studies the complex behaviors of the people in power, various political actors, such as the government administration, opposition ad the subjects which are the masses.

Why is the sun's renewable energy important to animals?
shepuryov [24]

Answer:

2. they eat plants that get their energy from the sun

Explanation:

Based on the way energy flows through an ecosystem, animals could not survive if they did not have the source of plants. So, the sun's renewable energy is important to animals because the sun helps them grow their food.

I hope this helps and makes sense!

Determine the pHpH of an HFHF solution of each of the following concentrations. In which cases can you not make the simplifying
PIT_PIT [208]

The question is incomplete, complete question is :

Determine the pH of an HF solution of each of the following concentrations. In which cases can you not make the simplifying assumption that x is small? (K_a for HF is 6.8\times 10^{-4}.)

[HF] = 0.280 M

Express your answer to two decimal places.

Answer:

The pH of an 0.280 M HF solution is 1.87.

Explanation:3

Initial concentration if HF = c = 0.280 M

Dissociation constant of the HF = K_a=6.8\times 10^{-4}

HF\rightleftharpoons H^++F^-

Initially

c          0            0

At equilibrium :

(c-x)      x             x

The expression of disassociation constant is given as:

K_a=\frac{[H^+][F^-]}{[HF]}

K_a=\frac{x\times x}{(c-x)}

6.8\times 10^{-4}=\frac{x^2}{(0.280 M-x)}

Solving for x, we get:

x = 0.01346 M

So, the concentration of hydrogen ion at equilibrium is :

[H^+]=x=0.01346 M

The pH of the solution is ;

pH=-\log[H^+]=-\log[0.01346 M]=1.87

The pH of an 0.280 M HF solution is 1.87.

Free-energy change, ΔG∘, is related to cell potential, E∘, by the equationΔG∘=−nFE∘where n is the number of moles of electrons t
mart [117]

Answer:

a)\Delta G=372490 J

b)\Delta G=-568614 J

Explanation:

a) The reaction:

Mg(s) +Fe^{2+}(aq) \longrightarrow Mg^{2+}(aq) + Fe(s)

The free-energy expression:

\Delta G=-n*F*E

E=E_{red}-E_{ox]

The element wich is reduced is the Fe and the one that oxidates is the Mg:

-0.44V=E_{red}-(-2.37V)=1.93V

The electrons transfered (n) in this reaction are 2, so:

\Delta G=-2mol*96500 C/mol * 1.93 V

\Delta G=-372490 J

b) If you have values of enthalpy and enthropy you can calculate the free-energy by:

\Delta G=\Delta H - T* \Delta S

with T in Kelvin

\Delta G=-675 kJ*\frac{1000J}{kJ} - 298K*-357 J/K

\Delta G=-568614 J
