A reflex pathway stimulates the sympathetic nervous system to increase the heart rate. In this reflex pathway, the heart is the target.
Reflex pathway is the path travelled by a reflex action. A reflex is an involuntary action produced due to a sudden stimulus to the body. Any pathway consists of following 5 steps: sensor, sensory neuron, control center, motor neuron, and muscle.
Sympathetic nervous system is the part of the brain responsible for activating the flight-and-fright responses of the body. This is responsible for increasing the heart rate of the body, dilation of pupils, piloerection, etc. The hormones that help in activating this nervous system are: the epinephrine and the norepinephrine.

Enzymes are proteins capable of recognizing and binding to very specific small molecules, such as glucose. Which level of protein structure most directly leads to this binding specificity?.
Enzymes are proteins capable of recognizing and binding to very specific small molecules, such as glucose. The tertiary structure of protein leads to this binding specificity.
The tertiary structure of proteins helps in building complex three-dimensional structures proteins. This three-dimensional structure allows proteins to represent their functional groups on the outer side which can then easily interact with other molecules such as glucose.
The specificity of the proteins is maintained by the three-dimensional structure that it gets as a result of the tertiary structure.
The specific three-dimensional structure of enzymes where specific molecules can fit is referred to as the active site of the enzyme. Due to this specificity, only the right molecules can fit into the active site.

Transmission of nerve impulses relies on the concentrations of ______ in the neuron.
Transmission of nerve impulses relies on the concentrations of sodium and potassium in the neuron.
Why is conduction at synapses one way?Conduction at synapses is always one way because, at each synapse, only one neuron has neurotransmitter (which is released into the synaptic cleft), while the other has the neurotransmitter receptors that open Na+ ion channels. Therefore, the transmission can never be in the opposite direction.
The sodium potassium pump maintains an electrical gradient across the plasma membrane of a neuron when it is not actively transmitting a nerve impulse.

Translation of mRNA- There are two main components to it: a big and a small subunit. The transfer RNAs, or tRNAs, that are floating in the cell are brought together with the mRNA to be translated by the ribosome. mRNA and the polypeptide chain that the cell must assemble are coordinated by adaptor molecules called tRNAs.
Translation of amino acid- As ribosomes move along an mRNA strand during translation, they assemble the sequence of amino acids specified by the mRNA to create a protein with the aid of proteins known as initiation factors, elongation factors, and release factors.
UAC serves as the anticodon for AUG. This tRNA is bringing in a methionine at its other end and has the anticodon UAC. No water molecule is produced as UAC is the first amino acid.

After cellular replication, a nucleolus failed to reform in the nucleus. What would be the most immediate implication of this failure?
If after cellular replication, a nucleolus failed to reform in the nucleus, the most immediate implication of this failure would be the inability to make ribosomes.
The nucleolus, which is the location of rRNA transcription and processing as well as ribosome assembly, is the most noticeable substructure within the nucleus. As was covered in the chapter before, cells need a lot of ribosomes to produce all the protein they need. Mammalian cells that are actively growing, for instance, need to produce between 5 million and 10 million ribosomes during every cell division. The nucleolus was created as a ribosome manufacturing facility to meet the demand for extensive rRNA production and ribosomal subunit assembly.
Inability to make ribosomes is the most immediate implication when a nucleolus is failed to reform in the nucleus.

What is Genes?The term "gene" can refer to a variety of biological concepts. Mendelian genes are the fundamental building blocks of heredity, and molecular genes are DNA sequences that are translated to create functional RNA. Noncoding and protein-coding genes are the two different categories of molecular genes.
The DNA is initially transcribed into RNA when a gene is expressed. A protein that fulfills a function can be directly generated from the RNA or it can serve as the intermediary template. Phenotypic qualities are passed down through gene inheritance from an organism to its progeny. Numerous DNA sequences known as genotypes are composed of these genes. What the phenotypes will be depends on the genotypes as well as the environment and developmental variables.

The egg will hatch when it reaches a temperature of 36°C. Zone of Hatching Potential is the official name of this region. It ranges from 35 to 40.5°C.
What exactly is a zone of potential for a hatch is "Temperatures between 35 and 40.5°C (84.5 and 104.9°F) are permissible for egg emergence"
The ideal temperature (for hens) is 37.5 degrees Celsius (99.5 degrees Fahrenheit); above this temperature, the hatch rate will be reduced and there will be a greater proportion of deformed and crippled chicks.
Any temperature increase above 40.5°C (104.9°F) will result in the death of all embryos.
Growth will be hindered and mortality will rise at constant temperatures in this range, although below the optimal.
