Explanation:
why would one gene work as a barcode for one species and not for another
One gene work as a barcode for one species and not for another because for different species different barcodes are used.
Every specie is different than another organism genetically so it also needs different barcodes for every other specie. If all the species are made up of the same gene then we can say that one barcode is used for all of them but its not the case.
Every organism has different and its own gene so one gene barcode is not acceptable for all species but for the original one so we can conclude that one barcode is used for one species and not for another.

Cetaceans (whales, dolphins, and porpoises) are all Mammals. Whales usually are larger and slower in the water. Porpoises normally do not have a pronounced beak as a dolphin would. Dolphins have a curved dorsal fin. Dolphins and Porpoises are extremely intelligent. They are warm-blooded. All dolphins are whales, but not all whales are dolphins. Different animals live in different areas. Killer whales are adapted to colder areas, and they stay in the colder water. Bottlenose dolphins are best suited for warmer areas such as the Atlantic Ocean, so they will have less body fat or flubber because they live in a warmer climate. The Killer Whale will need more body fat because of the colder temperatures. They have smooth bodies to help them swim. They have tiny hairs, but as they age, the hair disappears. They can stay underwater longer based on their breathing and extract oxygen from water; they make super high pitch noises that Bounce off objects in the water Back towards the Dolphins to help determine the location; this is called Echolocation.

d. The skull is flexible which allows the brain to grow
Answer:
c. The skull is hard which protects the brain from being injured
Explanation:
Answer:
The one that makes sense is C.) "The skull is hard which protects the brain from being injured." here's why:
Explanation:
The skull performs vital functions. Mainly, it supports and protects the head's soft tissues. The baby's skull is soft but as the bones developed, the bones of the skull form a tough, fibrous membrane and slowly fuse to form a single skull. The mandible is the only bone that separates from other parts of the skull. The skull or known as the cranium in the medical world is a bone structure of the head. It supports and protects the face and the brain. The adult skull has a total of 22 individual bones. They don’t move and united into a single unit. The skull performs vital functions. Mainly, it supports and protects the head’s soft tissues. The baby's skull is soft but as the bones developed, the bones of the skull form a tough, fibrous membrane and slowly fuse to form a single skull.

What would happen to skin cells if mitosis did not take place
Answer:
Skin cells would die and not be replaced.
Explanation:
Which term refers to the microscopic physical gap between the presynaptic and postsynaptic neurons at a chemical synapse
The gap between the presynaptic and postsynaptic neurons at a chemical synapse is the Synaptic cleft.
The neurons are the smallest units of the nervous system. They are equally referred to as the nerve cells.
The presynaptic neurons that receives the fired action potential through its axon terminals.
This leads to release of neurotransmitters found in the synaptic vesicles of the presynaptic neurons.
These neurotransmitter are released into the physical gap between the presynaptic and postsynaptic neurons called the Synaptic cleft.
The neurotransmitters are then received by the postsynaptic neurons.
Therefore, the gap between the presynaptic and postsynaptic neurons at a chemical synapse is the Synaptic cleft.

What is Respiratory System?The respiratory system is the network of organs and tissues which helps with breathing that includes the airways, lungs, and blood vessels. The muscles that power the lungs are also part of the respiratory system. They work together to move oxygen throughout the body and to clean up waste gases like carbon dioxide.
Respiratory system consists of following parts like
Nose--> Mouth--> Pharynx --> Larynx --> Trachea --> Bronchi --> Bronchioles --> Alveoli
The respiratory system has many functions others than inhaling (breathe in) and exhaling (breathe out), it:
It allows talking and smelling.It warms the air to match the body temperature and moisturizes it to the moisture level the body needs.It transports oxygen to the cells in your body.It removes waste gases, including carbon dioxide, from the body when you exhale.It protects the airways from harmful substances and irritantsThus, following are the parts of Respiratory system:

To maintain homeostasis, ADH functions via a ______ feedback mechanism that responds to blood ______ concentration.
Answer:
negative, salt
Explanation:
ADH functions via a negative feedback mechanism that responds to blood salt concentration to maintain homeostasis.
What is homeostasis?In order to maintain a constant state between internal conditions and the external environment, a cell's response to its environment is known as homeostasis.
Because of their complexity and uniqueness to living things, the coordinated physiological responses that keep the majority of the body's dynamic equilibrium in place have been given the name "homeostasis."
Ex: When it's cold outside, we start to shiver and use energy to stabilize our body temperature. This is where the cell regulates cell temperature, fluid balance, sugar balance, etc. through it.
Therefore, there is negative feedback that responds to blood salt concentration.

Kinetic energy is described as
Question 1 options:
Decreasing energy
Stored energy
Elastic
Movement
Answer:
elastic
Explanation:
The kinetic energy of a body can be decreased in two cases: When it is stored in the form of potential, for example: elastic or gravitational energy. Or when there are dissipative forces capable of transforming it into other forms of energy, as does the friction force. Which transforms kinetic energy into thermal energy.
