Answer:

C

Explanation:

A. is incorrect because the cell displayed is an animal cell not a plant cell, so it cannot photosynthesize. The organelle shown is actually the ER.

B. is incorrect because the structure labelled is the nucleus, not a vacuole. Vacuoles store substances like waste, not DNA.

C. Is correct because the pickle-like organelle is the Mitochondria, also known as the powerhouse of the cell due to cellular respiration taking place there.

D. Is incorrect because the cellular membrane of the animal cell is not rigid like the cell wall of the plant cell, instead it is more semi-permeable.

Hope I could help! :)

Which of the following are NOT correct based on Darwin's theory of evolution?
Black_prince [1.1K]

Answer:

D variations in individuals are not heritable

Explanation:

Genetic variation in individuals is what drives evolution. In a population of individuals in an environment, with the adequate resources, overpopulation can occur. However, resources are usually a limiting factor for population growth: there is not sufficient food/shelter etc. for everyone to survive.

Some individuals are better suited to success in the environment. This is because of random variation in their DNA that has arisen that give them a selective advantage. This allows them to thrive, take advantage of the limited resources over other members of the population, and be more likely to survive to reproductive age. This is natural selection.

Because this variation is genetic (in the DNA), they can then pass it on to their offspring. Over time, this leads to evolution over time.

Which combination describes the plasma membrane?
lilavasa [31]

<u>Answer</u>: C) Hydrophobic interior, hydrophilic exterior

<u>Explanation</u>:

  • The <em>plasma membrane</em> of the cell defines its boundary and separates its internal components from the external environment.
  • The basic components of the plasma membrane include phospholipids, carbohydrates, proteins, and cholesterol.
  • The plasma membrane is a phospholipid bilayer, with <em>hydrophobic</em> tails of the phospholipid projecting <em>inwards</em> and the <em>hydrophilic</em> exterior in contact with the external environment.
  • <em>Due to this, the plasma membrane has a hydrophobic interior and hydrophilic exterior. </em>

Monocot seed vs. dicot seed characteristics ?
mash [69]
Monocots have only one seed leaf inside the seed coat. It is often only a thin leaf, because the endosperm to feed the new plant is not inside the seed leaf. Dicots have two seed leaves inside theseed coat. They are usually rounded and fat, because they contain the endosperm to feed the embryo plant. [Credit to: Monocots and Dicots - The seed site]
