The two upper parts or chambers of the heart are called Atria's,
they're separated from their lower counterparts the ventricles by an interatrial septum. All the Atria's do is receive blood returning from the heart to the body.

List 3 factors that can speed up the rate of chemical reactions
zysi [14]

Answer:

  1. Temperature
  2. Greater Surface Area
  3. Catalysts

Explanation:

Temperature

  • An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).

Greater Surface Area

  • The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. ... more particles are exposed to the other reactant. there are more collisions. the rate of reaction increases.

Catalysts

  • A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.

Hope this help!!!

Verizon [17]

Answer:

  • to have cell walls made of chitin
  • eukaryotic heterotrophs

Explanation:

Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.

The eukarya domain is composed of the Protist, Fungi, Plantae, and Animalia kingdoms.

Kingdoms include different phyla closely related.

The Fungi kingdom includes yeasts, molds, and mushrooms. All of them are characterized by the same general aspects.

All the members of the kingdom

  • Lack mobility, growing on the ground, organic matter, or other surfaces.
  • They all have a rigid cell wall composed of chitin.
  • They grow like hyphae, which are cylindrical uniformed structures that might reach many centimeters in length.
  • Heterotrophic nutrition. The species can not produce their own food, so they decompose organic matter and get the nutrients from there.
  • Reproduction is by spores, which are resistant to adverse environmental conditions.

How do we inherit traits from our parents
Masteriza [31]

Answer: Through genes

Explanation:

When a baby is made the parents both pass on traits (genes) to the baby through DNA. The traits that the baby takes are determined by dominant and recessive traits.

Example: If both parents have brown eyes which is a dominant trait the baby will have brown eyes.

Whitepunk [10]

Answer:

INTERNEUTRONS

Explanation:

INTERNEUTRONS

Interneutrons are really the highest number of neurons and spinal cord. They are accountable for the diverse communication system of the nervous system and try and resolve between inputs and outputs.

Interneurons are groups of nerve cells commonly found in nervous system integrative areas where axons & dendrites are restricted to a specific area of  brain.
