Information from the taste buds travels to an area of the.
Information from the taste buds travels to an area of the frontal and temporal lobes of the brain.
What are taste buds?Taste buds are present in the tongue. They are responsible for the taste of whatever we eat. Taste buds are of different types. Like bitter, sweet, salt, and sour. They are different taste buds and are present in the different regions of the tongue.
The frontal and temporal lobe of the brain is responsible for the taste of food and other things. The frontal lobe is present in the frontal part of the brain, and the temporal lobe is on the side of the brain above the ears.
Different lobes of the brain are responsible for different works of the body.
Therefore, the frontal and temporal lobes of the brain get information from the tongue.

What is the main difference between natural selection and
selective breeding? in selective breeding
humans allow nature to control the reproduction of species
humans choose plants or animals for reproduction
the strongest will survive and have more offspring
the organisms with the most genetic variation will reproduce
Answer:
humans choose plants or animals for reproduction
Explanation:
This can be seen in the farming industry with livestock and crops alike. Crops are usually chosen for a genetic resilience (like to arid, dry areas) and are reproduced with intervention from humans. This doesn't happen in the wild, therefore it is natural vs the unnatural and purposeful human intervention.
The testes and ovaries both release the hormone testosterone. Please select the best answer from the choices provided T F.
Testosterone is a hormone that regulates puberty, function and the development of the male and female organs. The testes and ovaries both release the hormone testosterone.
What is the role of testosterone?In males, the Leydig cells of the testis and in females, the ovaries produces and releases the hormone testosterone. Also, some amount of the hormone is released by the adrenal gland.
It is major reproductive growth, functioning and stimulating hormone that is also responsible for the physical development of the organism during puberty.
Males have high levels of this hormone as females as they are essential for sperm development and some male physical characteristics.
Therefore, the statement is true.

A person starts to eat a hamburger. As she takes a bite and chews, an enzyme called salivary lipase helps to begin the process of fat digestion. Which of these is the BEST description of the role of enzymes in digestion?
Answer:
Role of enzymes in the human body
Explanation:
The chemical reactions that keep us alive - our metabolism - rely on the work that digestive enzymes do. They help to accelerate (catalyze) chemical reactions in the human body.
In some cases, they can cause a chemical reaction millions of times faster than they would without them.
Important functions of enzymes:
Digestive enzymes help the body break down larger complex molecules into smaller ones such as glucose, so it uses them as fuel.
Every cell in our body contains DNA. Each time the cell divides, this DNA must be copied. The process is called DNA replication . Enzymes help in this process by developing the DNA helix and copying the information.
Liver enzymes break down toxins in the body.
Enzymes are especially needed for respiration, digestion, muscle and nerve function, among other important roles.
Answer:
C. Enzymes are proteins that speed up the process of chemcially breaking down food molcules.

Answer:
[tex]\huge\boxed{\sf Endocytosis}[/tex]
Explanation:
B-cells engulf an antigen by endocytosis.
Endocytosis:
The process by which cell takes up external materials by fusing them with plasma membrane is called endocytosis.
After engulfing the antigen, B-cells become sensitive to the pathogen.

Green algae are divided into two main groups, the charophytes and the __________.
Answer:
The green algae are subdivided into the chlorophytes and the charophytes.
Explanation:
This type of receptor, once bound by ligand, can change conformation to allow specific substances to flow down their concentration gradient. This type of receptor is referred to as ____________ . This type of receptor is not an enzyme itself, but is bound to a protein that can exchange GDP for GTP and then stimulate effector proteins, which are usually enzymes. This type of receptor is referred to as ____________ . This type of receptor is a transmembrane receptor. It has an extracellular domain that binds to ligand, and an intracellular domain that can directly phosphorylate other proteins. This is an example of ____________ . This type of receptor binds to hydrophobic ligands. This type of receptor is referred to as ____________ .

11. Make a checklist for
a client to use to
determine normal and
abnormal behaviors of a
pet. Include & label
behaviors that require an
owner to seek veterinary
attention.
Veterinarians have a great opportunity to save pets’
lives by recognizing that behavioral medicine is as
important as any other field of veterinary medicine,
and can routinely be incorporated into each veterinary
visit. Because most veterinarians never received education in veterinary school about feline behavior, and do
not have the time and resources to study all the latest
research and develop behavior protocols, the panelists
have worked to develop a concise, updated and “user
friendly” document that can be easily implemented.
The guidelines include the following information:
• Emphasis is on prevention, from pre-adoption or the
first veterinary visit, through senior life. Preventing
behavior problems should be an important part of total
wellness care. A list of behavior questions intended for
inclusion in the medical history questions used at each
appointment is provided to aid in early detection and
intervention of behavior problems.
• An outline is provided for guidance regarding how to
create realistic expectations about living with a cat. This
will encourage cat owners to provide positive outlets to
allow normal behavior, but in ways that clients will consider acceptable.
• Several of the appendices can be used for both prevention and treatment and can be made into client
handouts; these will delegate client education to the
veterinary support team and be used to facilitate the
veterinarian’s role in client education.
• A developmental table specifying home and veterinary
care needed at different stages of life is included. This
can serve as an excellent poster or client information
handout to help clients understand their responsibilities for home and veterinary care.
• Detailed information on behavior and environmental
enrichment is included to help prevent many of the
most common behavior problems.
• Suggestions regarding prevention and treatment of
obesity, the most common consequence of domestication of cats, are provided.
• To help veterinarians better handle routine behavior
concerns (eg, inappropriate elimination) a rational first
approach to the problems seen day-to-day is included.
• Behavior counseling and treatment, including behavior
modification and environmental enrichment, are discussed in detail. For cats needing medical treatment,
important drug information including dosing and
tapering of medication is provided. Information on
where to refer if needed is also provided.
• Information is provided that will promote comprehensive, state-of-the-art, holistic care that incorporates
both the physical and psychological well-being of our
feline patients.
• These guidelines will help veterinarians raise client
awareness that they should turn to the veterinary profession for advice regarding behavior, just as they do
with any medical concerns.
How does the scientific method attempt to reduce observer bias when explaining natural phenomena?
Explanation:
The scientific method is focused on experiments to prove/disprove a hypothesis.
A number of experiments start with a question;example/ what caused mold to grow on human skin?
this is when u organize a "control group,"
( recieving a placebo, or told information they have to follow).
your second group, gets a medication or a scenario to prove the hypothesis is true or false.
once both sides document their findings, scientists discuss which one is true..
