<h3><u>Answer;</u></h3>

The above statement is <u>false </u>

<h3><u>Explanation</u>;</h3>
  • The chordae tendineae are a group of tough, tendinous strands in the heart.
  • <em><u>The chordae tendineae play a vital role in holding the atrioventricular valves in place while the heart is pumping blood</u></em>.
  • The chordae tendineae connect the papillary muscles to the tricuspid valve and the mitral valve in the heart.
  • Papillary muscles are located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves via the chordae tendineae and contract to prevent inversion or prolapse of these valves.

How are homeostasis and cellular respiration mutually dependent on one another?
Arturiano [62]

Cellular respiration describes the process of oxygen and glucose and converting into water and carbon dioxide. Homeostasis is a term which refers to biological processes in which living things must maintain stable and equal conditions for survival. Cellular respiration which uses oxygen and glucose must be able to sustain life by releasing energy which is called ATP, the ATP which is produced enables many biological processes that keeps organisms alive. Cells need energy to grow, move, and function. The process of homeostasis enables cellular respiration to produce enough molecules which can sustain the development of the cell. Without homeostasis cellular respiration would cease to function and without cellular respiration the process of homeostasis would not occur. Homeostasis regulates how much molecules have to be expended in order to produce energy for the process of cellular respiration.

Protists with the capabilities to perform photosynthesis and to absorb nutrients from dead organisms are called ______________.
alisha [4.7K]

Answer:

mixotrophs

Explanation:

Myxotrophism or myxotrophy, in biology, is the name given to the quality of the living being with autotrophic and heterotrophic characteristics. That is, it is capable of producing its own food from carbon dioxide fixation (through photosynthesis or chemosynthesis), but it can also feed on other inorganic or organic compounds. Mixotrophic can be either eukaryotic or prokaryotic.

Carnivorous plants are commonly cited as myxotrophic organisms in the wrong way because all their food comes from photosynthesis. These plants only depend in part on the nitrogen contained in animal proteins that they digest. This dependence occurs because the carnivorous plant is native to areas with poor, soggy soil, scarce of nitrates, essential for the synthesis of the chlorophyll molecule.
