Answer:

a. My list is the following:

1. presence of photosynthetic pigments

2. presence of cell wall

3. body symmetry pattern

4. presence of cell nucleus

5. presence of specialized organelles

6. presence of hair

7. presence of mammal glands  

8. niche (e.g., terrestrial or marine habitats)

9. diet (food habits)

10. position of a particular muscle

Explanation:

b. In the list above, traits such as the presence of a cell nucleus or specialized organelles can be used to classify organisms at the kingdom level (since these phenotypic features are observed in eukaryotic organisms but not in prokaryotes). In a similar mode, animals may exhibit two different body symmetry patterns: radial (around the central axis) and bilateral (two sides: left and right), thereby symmetry body can be used to classify organisms within the animal kingdom. Other features used to classify species at high levels include the presence of photosynthetic pigments in green plants (chlorophyll) and bacteria (xanthophyll), presence of cell walls in plants (composed of cellulose,)  and fungi (composed of chitin), presence of hair and mammal glands (mammals), etc. On the other hand, ecological differences (e.g., food habits, niche) and minor anatomical differences (e.g., the position of a particular muscle) are helpful to classify species at the family/genus level.

Hi,

I am Nucleus of the cell. I am the most important part of the cell and i have genetic material that is transferred to the offspring upon reproduction. I also supervise many important processes of cell like synthesis of proteins.

I will take you on the trip of our whole cell where you will be able to meet different organelles and know a little about their roles in cell. Let us meet them one by one:

1) Nucleolus: It is a darkish and roundish structure that resides inside me. Its role is in the synthesis of an important type of RNA called ribosomal RNA.

2) Nuclear membrane: This membrane surrounds me and is contains small pores for the movement of ribosomal RNA and proteins. Due to this surrounding DNA stays inside me and donot leaves me.

3) Golgi Complex: This is like a packaging and storing organelle of cell that processes and packs the proteins and exports them outsise or inside the cell. Their secretions include digestive glands, saliva, oils etc.

4) Rough Endoplasmic Reticulum: It consists of several long canals that form a series running throughout the cell and contains ribosomes attached with them. They are the organelles which transport proteins to the golgi complex for their packaging.  

5) Smooth Endoplasmic Reticulum: It has an important role in the detoxification process converting toxic substances into less toxic forms. They are in structure similar to rough endoplasmic reticulum except that they donot have ribosomes attached to them.

6: Centrioles: They are important in the process of cell division and are present in animal cells only.

7:Mitochondria: This is called as power house of the cell because all the processes that convert food into energy take place in this part. You can see it has two membranes outer is smototh while inner forms foldings.

8: Ribosomes and Free Ribosomes- They are freely floating in the cell or attached with endoplasmic reticulum, They have role in protein synthesis.

9: Lysosomes: They have an important function because they remove worn out and old organelles by digesting them. Therefore, they contain good digestive enzymes.

Hope it helps!

Help me in my hw ,An air bubble in a jar of water shines brightly.Why?Correct answer will get brainlest and thx but plz don't sp
Amanda [17]

Answer:

As the bubble is a spherical entity, the probability of total internal reflection from the watery films is high due to its curvature. As a result, most of the light rays get reflected and therefore the air bubble shines brightly with some sparkling in water

What factor is described as sexual
mr Goodwill [35]

Answer:

The correct answer is - D. natural selection.

Explanation:

Sexual selection takes place due to competition between individuals of the intraspecies same-sex and of mate choice which driving the evolution of reproductive traits.

Sexual selection is a mode of natural selection as it leads to the evolution of specific traits. Other examples or options are not related to sexual selection directly and are not affected by sexual selection.
