This is because plants has cell wall while dog doesnt have. <span>A </span>cell wall<span> is a structural layer surrounding some types of </span>cells<span>, situated outside the </span>cell<span> membrane. It can be tough, flexible, and sometimes rigid. It provides the </span>cell<span> with both structural support and protection, and also acts as a filtering mechanism.</span>

Do autotrophs need to perform cellular respiration?
nydimaria [60]
Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.

Technological advances had helped reveal that the ocean floor was not flat, as once believed, but instead was marked by 50,000-k
poizon [28]
<span>By the late 1960s, scientists had developed the theory of plate tectonics based on a range of new evidence. Technological advances had helped reveal that the ocean floor was not essentially flat, as once assumed, but instead was marked by 50,000-kilometer-long (31,000-mile), 3,000-meter-high (9,800-ft) ridges and 11-kilometer-deep (7-mile) trenches. Scientists found striking patterns related to these features. They found that the youngest oceanic crust is located nearest the mid-ocean ridge and the oldest crust is nearest the trenches. They also detected a pattern of alternating magnetic polarity along the ocean floor, which emanated from the ridge tops. These two pieces of evidence, coupled with the fact that volcanic activity and island-building occurred most commonly at ocean trenches, suggested that new crust was created at mid-ocean ridges and destroyed at ocean trenches. Scientists Harry Hess and Robert Dietz used this evidence to revive and expand Holmes' convection theory into the theory they called "seafloor spreading." Finally, Wegener's notion of continental drift was coupled with a mechanism that could explain the movement of tectonic plates.</span>

You are operating a powerboat at night. Your red sidelight must be visible to boats approaching from which direction(s)?
Degger [83]
I believe the answer is head-on and port (left). The side lights are usually visible to vessels approaching from the front or the side. The red light usually indicates a vessel's port (left) side while the green light indicates a vessel's starboard (right) side. These lights ensure that there is safety at night as the vessels navigate.

Define the five systems. Be sure to include enough information to distinguish each system from the others. (Site 1)
VladimirAG [237]
By definition, a body system is primarily comprised of different organs and tissues that work one another to achieve a common body process. These body systems would include:

Circulatory system - concerns with the circulation of blood
Digestive system - breaking down of food particles 
Skeletal system - composed of bone structures serving as our body's framework
Nervous system - composed of nerve cells that responds to different stimuli
Respiratory system - concerns of utilising the entry of oxygen and the exhalation of carbon dioxide.
