In the text area below compare and contrast a cell membrane and cell wall.

Answers

Answer 1
Answer:

Both cell wall and cell membrane are important parts of the cell, although they each have unique properties and purposes.

Cell membrane:

  • Found in both animal and plant cells.
  • Consisting of a protein-embedded phospholipid bilayer.
  • Flexible and selectively permeable, with the ability to control substances entering and leaving the cell.
  • Plays a role in cell signaling, cell identity, and interactions with the outside world.
  • Essential for maintaining the integrity and appearance of cells.
  • Provides no structural support to the cell.

Cell wall:

  • Found in various protists, bacteria, fungi and plant cells.
  • Chitin is composed of complex polysaccharides such as cellulose or peptidoglycan.
  • Stiffens and provides structural stability and protection to the cell.
  • Allows preservation of cell structure and prevents osmotic pressure-induced cell rupture.
  • Provides protection against contamination and external shocks.
  • Compared to cell membrane, less elastic and selectively permeable.

Answer 2
Answer:

A cell membrane, seen in plant and animal cells, is selectively permeable and made of a phospholipid bilayer.

The cell membrane and cell wall control what enters and leaves the cell.

The cell wall is seen in a plant cell, gives shape to the cell, and stores carbohydrates.

The cell wall is selectively permeable and made of cellulose, which causes plants to have a rigid structure.

Before DNA was discovered, in which materials did scientists think the genetic material was stored?

Answers

Answer: We all know that DNA act as repository of genetic information in most organism. But before the discovery of DNA it was thought that proteins act as a genetic material because protein is the final product of the cell dogma of cellular system and proteins helps in the formation of tissues and organs.

The alleles BB for black hair and LL for long hair are part of that cat’s

Answers

Is it the Genes? ???????

Hungaaroons can have straight hair, wavy hair, or curly hair. Straight hair is caused by having two of the same allele (SS). Curly hair is the resultsof having two curly hair alleles (CC), Wavy haired individuals are heterozygous. What type of inheritance pattern does this trait follow?

Answers

Answer:

Wavy haired would be SC, seeing as it is "heterozygous," meaning it has one of each allele. This is called incomplete dominance, where neither allele is expressed fully over the other.

Mr. Morales is teaching a lesson on classification. He says that spiders are classified as a different group than insects because they have eight legs instead of six legs. He explains that spiders evolved first. Mr. Morales also says that having eight legs is the derived trait that separates the two groups. Antonio thinks Mr. Morales is wrong. Which piece of information is Antonio considering?

Answers

Answer:

answer is C

Explanation:

antonio is considering that since the spiders came first, it cannot have 'derived traits' from anything. spiders themselves are the ancestralspecies of the insects

Which of the following neuronal pools leads to a long lasting output from a single input and so may be involved in higher order thinking? 1) parallel-after-discharge 2) converging 3) reverberating 4) diverging

Answers

Answer:

1) parallel-after-discharge

Explanation:

Neural circuits are defined as the connections between neurons. These neural circuits are of four types:

  1. Diverging circuits, found in sensory and motor neurons, diverge a single nerve impulse to multiple neurons in the circuit, amplifying the original signal.
  2. Convergent circuits, also found in sensory and motor pathways, converge multiple nerve impulses into a single one. These pathways are predominantly involved in inhibition and stimulation.
  3. Reverberating circuits, involved in control of sleep-wake cycle and breathing, consist of a neuron chain along which the impulse travels.
  4. Parallel after discharge, involved in cognition and mental processing, are a combination of convergent and divergent circuits. They result in an output impulse that lasts at least 15 m/s after the input impulse ends.
