How is codominance different from incomplete dominance?

1 answer:

7 0

With incomplete dominance we get a blending of the dominant & recessive traits so that the third phenotype is something in the middle In COdominance, the "recessive" & "dominant" traits appear together in the phenotype

What mass of water is required to react completely with 157.35 g CO2? (Molar mass of H2O = 18.02 g/mol; molar mass of CO2 = 44.0

Ghella [55]

You must use 64.43 g H₂O.

Balanced chemical equation: H₂O + CO₂ → H₂CO₃

Moles of CO₂ = 157.35 g CO₂ × (1 mol CO₂/44.01 g CO₂) = 3.5753 mol CO₂

Moles of H₂O = 3.5753 mol CO₂ × (1 mol H₂O/1 mol CO₂) = 3.5753 mol Fe

Mass of H₂O = 3.5753 mol H₂O × (18.02 g H₂O /1 mol H₂O) = 64.43 g H₂O

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.

Which of the following best explains why ionic crystals are brittle?

Natalka [10]

Packing

Explanation:

Ionic crystals are brittle due to the tight packing of their crystals. This provides little to no mobility between one another.

Brittleness implies having little to no elasticity.
Ionic crystals are held together by strong crystal lattice forces
These forces prevents crystals from freely rotating and moving space.
It holds them rigidly and fixed in place.
Ionic crystals are hard and held electrostatic forces.

When an unknown amine reacts with an unknown acid chloride, an amide with a molecular mass of 163 g/mol (M = 163 m/z) is formed.

DanielleElmas [232]

Answer:

As the molecular mass of given amine is 163 g/mol (a odd number) it means that this compound contains a odd number of Nitrogen atoms. We will first apply Rule of Thirteen to get the molecular formula.

Rule of Thirteen:

First divide the parent peak value by 13 as,

= 163 ÷ 13

= 12.53

Now, multiply 13 by 12,

= 13 × 12 (here, 12 specifies number of carbon atoms)

= 156

Now subtract 156 from 163,

= 163 - 156

= 7

Add 7 into 12,

= 7 + 12

= 19 (hydrogen atoms)

So, the rough formula we have is,

C₁₂H₁₉

Now, add one Nitrogen atom to above formula and subtract one Carbon and 2 Hydrogen atoms as these numbers are equal to atomic mass of Nitrogen atom as,

C₁₂H₁₉ -------N--------> C₁₁H₁₇N

Also, as shown in ¹³C-NMR there is one peak around 180 ppm and the peak at 1661 cm⁻¹ in IR spectrum is characteristic to carbonyl group hence, we will add one oxygen atom to the chemical formula accordingly. i.e.

C₁₁H₁₇N -------O--------> C₁₀H₁₃NO

Molecular Formula: C₁₀H₁₃NO

Also,

In NMR the the four peaks around 120 ppm are assigned to a mono substituted benzene ring.

The absence of IR peak above 3200 cm⁻³ also confirms that the amine is tertiary in nature and there is no hydrogen attached to the nitrogen atom.

It can be observed that the peaks in upfield are duplicating. This can be due to the presence of rotamers of said compound.

The most plausible structure for given data is shown below, and the resonance structure along with rotamers are also shown.

Which structures join with the cell’s membrane during exocytosis?

erma4kov [3.2K]

Answer:Exocytosis is also used to integrate new proteins into the cell membrane. In this process, the new protein is formed inside the cell, and migrates to phospholipid bilayer of the vesicle. The vesicle, containing the new protein as a part of the phospholipid bilayer, fuses with the cell membrane.
