If you were an electron, and your home town was your nucleus, what would you need to do in relation to your home town to emit li
Scilla [17]

Answer:

Option B, Move closer to your home town

Explanation:

The options for the given question are as follows -

A) Knock down your previous house and build a bigger one.

B) Move closer to your home town.

C) Move further away from your home town.

D) Stay where you are but speed up your daily life

Solution -

Electrons carry negative charge while nucleus carries positive charge due to the presence of positively charged proton ions and neutral ions (which has no charge). All the electrons are attracted towards the nucleus due to its positive charge. The orbit on which an electron revolves around a nucleus has higher energy level as compared to the energy levels located in between the space of electron and nucleus.  

While moving from a high energy orbital to a low energy level orbital, an electron releases some energy.  Hence, in order to move closer to home, electron needs to push itself toward the nucleus by releasing energy

Hence, the given option is B

Evgesh-ka [11]

Answer:

Explanation:

Proteins are involved in almost every function of cell and inside the body and each protein is specific for its role. Some of them are  

1) Protein constitute major part of structure of cell. Proteins are major constituent of cell membrane along with lipids.  

2)  Enzymes which are proteins in nature catalyze all the important chemical reactions inside and outside the cell e.g transporting material across the cell, synthesizing and repair of DNA

3) Hormones which are proteins play important role in the regulation of metabolic reactions inside the cell

4)  Regulation of cell division is performed by DNA-associated proteins  

5)  Proteins plays important role in storage of iron inside the cells

6) Proteins can be stored as fats inside the body and used as energy when needed by cells for its metabolic activities.

Based on this diagram, do you think that organisms of the same order will share a stronger evolutionary
dlinn [17]

From the diagram above, I dont think that organisms of the same order share a stronger evolutionary relationship than organisms in the same phylum. This is because, after kingdoms, the subsequent categories of increasing specificity are: phylum, class, order, family, genus, and species.

<h3>Levels in taxonomic classification</h3>

At each sublevel in the taxonomic classification system, organisms become more similar.

Organisms that share similar physical features and genetic sequences tend to be more closely related than those that do not.

Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among living organisms.

<h3>Phylogenetic tree</h3>

A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms

<h3>Taxonomical classification</h3>

Taxonomy is the scientific study of naming, defining and classifying groups of living organisms based on shared characteristics. There are seven main taxonomic ranks:

  • kingdom
  • phylum ( in animals )or division ( in plants )
  • class
  • order
  • family
  • genus
  • species.
