Name five adaptations to a land environment that plants have developed

Explain three differences between apomictic and automictic parthenogenesis.

a_sh-v [17]

Apomictic refers to plants and it means the offspring is genetically identical to the parent. Automictic means that gametes fuse after meiosis - which means offspring are genetically not identical to parents.

Can you identify the class of organic molecule to which these molecular structures and examples belong? Part A Sort these items

sattari [20]

There are four classes of organic molecules that are essential to all living organisms.

1. Carbohydrates:

Components: monosaccharides. Functions: energy for cell, raw material, energy storage, and plant cell support Ex: glucose, starch, glycogen, cellulose

2. Lipids (dont form polymers): Components: glycerol, fatty acid, components of a fat molecule Functions: energy storage, cell membrane components, and hormones Ex: fats, phospholipids, and steroids

3. Proteins:

Components: amino group, carboxil group, R group, and amino acid Function: enzyme, structural protein, movement, transport, communication, defense, storage, receive signals Ex: lactose, hair, tendons, muscles, hemoglobin, signal proteins, antibodies, egg albumin, receptor protein

4. Nucleic acids:

Components: phosphate group, nitrogeneous base, ribose or deoxyribose, nucleotide Functions: heredity, DNA

Ex: code for proteins, DNA and RNA

What kinds of traits do not evolve through natural selection?

Harrizon [31]

Natural selection doesn't favor traits that are somehow inherently superior. Instead, it favors traits that are beneficial (that is, help an organism survive and reproduce more effectively than its peers) in a specific environment. Traits that are helpful in one environment might actually be harmful in another.

(one again, I hope this helps ^^)

Which features are created by deposition from rivers? Check all that apply. rills deltas floodplains alluvial fans oxbow lakes

algol13

The features which create deposition from rivers are found in food plains, alluvial fan, and deltas.

Deposition is termed as a process whereby the transported materials by a river are being deposited.

When a river losses energy we say that there is deposition.

Where there is high flow of water in a river deposition is likely to occur because more sediments are being carried as well as erosion which is being caused.

1. Natural selection is the best of the organisms to live past hardships and survive, leaving the weakest to die. Survival of the fittest.

2. Adaptation is an organism changing to better themselves in a certain environment.

3. These moths were adapted to blend into their surroundings, so as to not be seen by predators.

4. Because of the pollution from the city, the tree’s bark turned from a lighter shade brown to a darker shade brown.

5. A majority of the moths were a lighter gray. With the changing color bark they were seen more by predators.

6. Adaption caused the first darker moths to appear because they learned they needed to blend into the new tree bark color.

7. The change from light to dark gray was very needed for moths. It explains natural selection for those moths who did not adapt to different color gray. Adapting the new tree bark color helped moths been less seen by predators therefor keeping their species more alive.
