Answer:

The options:

A) They both have ribosomes that are used to synthesize proteins and a cell membrane that serves as a selective barrier for the cell.

B) They both have a central vacuole that stores water and food and mitochondria that releases energy from glucose molecules.

C) They both have chloroplasts where conversion of light to chemical energy occurs and a cell membrane that serves as a selective barrier for the cell.

D) They both have a cell wall that provides protection and support and a nucleus where DNA is stored.

The CORRECT ANSWER IS A)

A) They both have ribosomes that are used to synthesize proteins and a cell membrane that serves as a selective barrier for the cell.

Explanation:

A) They both have ribosomes that are used to synthesize proteins and a cell membrane that serves as a selective barrier for the cell.✔✔✔

Judging from a model of the animal and plant cells, one can infer that ribosomes and cell membranes can be found in them.

B) They both have a central vacuole that stores water and food and mitochondria that releases energy from glucose molecules.❌

Animal cells lack central vacuole that stores water and food. Even if the vacoules are present in some, it's going to be small in size which is unlike that of plant cells that as a central vacuole that stores water and food.

C) They both have chloroplasts where conversion of light to chemical energy occurs and a cell membrane that serves as a selective barrier for the cell.❌

Animal cells lack chloroplasts due to the fact that they don't undergo photosynthesis. Animal cells obtain energy via metabolism of the nutrients it derives from food.

D) They both have a cell wall that provides protection and support and a nucleus where DNA is stored.❌

Animal cell lack the presence of a cell wall. The Animal cell is built mainly of cellulose, a type of carbohydrate, that serve as a means of protection to the cell.

nadya68 [22]

Answer:

C. Diploid condition

Explanation:

A Karyotype is the pictorial display that shows chromosome arrangement and number in a cell. The Karyotype shows any abnormalities in the nuclear material (chromosomes). In a carrot plant that was cloned from carrot root, the clones should possess the same features as the original plant.

A Karyotype of both plants i.e. clone and the original plant should show that their cells have a diploid number of chromosomes i.e. Two sets of chromosomes. Since a carrot plant is a diploid organism.

Surviving in the Antarctic is extremely difficult What advantage do Emperor Penguins have that animals in the less-harsh Arctic
Savatey [412]
Emperor penguins have the ability to 'recycle' their own body heat. The arteries and veins lie close together so that blood is pre-cooled on the way to a penguin's feet, wings and bill and warmed on the way back to the heart. Emperors' feet are adapted to the icy conditions

<h3>⇝ <u>Epidermis</u> :</h3>

Protective tissues includes epidermis & cork. Epidermis is basically a simple permanent tissue, protective in function. It forms one-cell-thick covering over all the parts of plant.

<h3>⇝ <u>Characteristics of Epidermis</u> : </h3>
  • Epidermis is formed of living cells, arranged in a single layer.

  • In aerial parts, epidermis is covered with a waterproof and noncellular waxy covering called cuticle.

  • Cells form a continuous layer, but in leaves epidermis has small openings called stomata.

  • Each stoma is guarded by a pair of bean-shaped guard cells which govern opening & closing of stomatal aperture.

<h3>⇝ <u>Functions of Epidermis</u> :</h3>
  • Epidermis protects the underlying tissues from mechanical injury, chemicals & infection.

  • Cuticle of epidermis protects against water loss & desiccation. It checks the rate of transpiration & evaporation and prevents wilting.

  • Stomata in the epidermis of leaves help in gaseous exchange during respiration & photosynthesis.
