They work like a lock and key. Each enzyme is designed to fit into a specific substrate. Well let me start by explaining what an enzyme is and then a subtrate. An enzyme is a protein that speeds up the chemical reaction in a living organism. An enzyme acts as a catalyst for specific chemical reactions, converting a specific set of reactants called substrates into specific products.
<h2>Resilience of bone</h2>
Explanation:
The resilience of bone comes from sacrificial bonds in or between collagen molecules
- Three major functions of bones includes
Providing structural support to the body
Providing protection to vital organs
Providing an environment for marrow (where blood cells are produced)
- There are two types of tissues which bones are composed of:
A hard outer layer called cortical bone which is strong, compact,dense and tough
A spongy inner layer called trabecular bone,this network of trabeculae is lighter and less dense than compact bone as a storage area for minerals (such as calcium)
- Bone is also consists of:
Bone forming cells (osteoblasts and osteocytes)
Bone resorbing cells (osteoclasts)
Non mineral matrix of collagen and noncollagenous proteins (osteoid)
Inorganic mineral salts deposited within the matrix
- Bone ends up being a good example of resilience because it is not static like it is perceived to be
Answer:
X-Chromosomes.
Explanation:
Characters determined by a gene located on only the X-chromosome are said to be sex-linked. Such traits show a different pattern of inheritance in males and females. For example, a recessive allele on the X-chromosome
• would be masked in a female if the corresponding allele on the other X-chromosome is dominant;
• would always be expressed in a male because the Y-chromosome does not have a corresponding(active) allele.
Thus, the female may posses a homozygous or heterozygous allelic pair for a sex-linked character, but a male will only have one allele for it.
A biological cycle, or rhythm, that is approximately 24 hours long is called a circadian cycle
The correct answer is C. Many chemicals will not be able to move out or into the neurons, disrupting communication.
The chemicals of outer membrane of neuron if blocked then a lot of chemicals will not have the ability to move in or out of the neuron.
Neuron is termed as a nerve which electrically excitable cell transmits, processes, and receives informaion through chemical and electrical signals.
The signals which are found between neurons they occur via synapses. By connecting to each other, neurons can form neural circuits. Spinal cord and brain which are found in the central nervous system, they are the primary components for the neurons.
The other components of neurons include, somatic nervous system and autonomic nervous system.
An original neuron consists of an axon and dendrites.
