The correct answer is option A, that is, development often causes habitat fragmentation, which can threaten biodiversity.
Fragmentation is usually illustrated as a reduction in some of all the kinds of natural habitats in a landscape, and the differentiation of a landscape into smaller and more isolated segments. With the development of the fragmentation process, the ecological influences will modify.
Fragmentation can be a result of natural procedures like floods, fires, and volcanic activity, but it is more generally caused due to human activities like an increase in the number of roads, housing developments, shopping centers, and parking lots.
With the enhancement in human activities, the effect of fragmentation become more. Eventually, it results in the devastating influences on the local species, a complete modification to the landscape, and the loss of the region's wilderness heritage.

The long bundle of neurons that carries messages to and from the body to the brain and is responsible for very fast, lifesaving reflexes is called the<u> spinal cord. </u>
<h3>
What is the espinal cord?</h3>
There are two organs involved in the central nervous system that function as control centers,
The spinal cord is a nerve tube placed in a hollow space left between vertebras along the vertebral column. The vertebrae's body protects the spinal cord.
It is made of nerves that take orders from the brain to the rest of the body and send messages from the body to the brain.
Reflexes acts are produced in the medulla, and the brain is not involved.
The nervous cells of the medulla have fibers that extend from the medulla to the body and are connected to sensory receptors.
When receptors receive stimuli, they send information to the nerve fibers, which take it to the brain. From the brain, they send a response.
The answer is spinal cord.

<span>The
peripheral nervous system (PNS) are all neurons located outside the brain and
spinal cord (which is the central nervous system [CNS]). There are two types of
peripheral nervous system: sensory (afferent) neurons and motor (efferent)
neurons. The former carries bits of information from the sense organs (touch,
smell, taste, hearing, and sight) around the body to the brain and spinal cord,
while the latter transports messages from the central nervous system (brain and
spinal cord to the muscles and glands.</span>
Answer:
<u>Active transport across membranes is like refilling an empty soda can after pouring the soda into a cup. It takes effort (energy in the form of ATP) to pour the soda back into the can, it wouldn't typically happen on its own.</u>
Explanation:
Cells use several transport mechanisms to move substances across their plasma membranes. Plasma membranes control all movement of substances through passive transport, which does not use energy; and active transport which requires chemical energy in the form of ATP.
Active transport moves substances out of cells against their gradients. In the cell, glucose can be transported inwards for respiration. However, because the internal environment is typically concentrated, (and glucose is needed in high amounts) this requires the use of transport enzymes and ATP.
