Answer:
C is the answer for the question
Why do the blood vessels going to the skin and internal digestive organs constrict and get smaller during a fight-or-flight response?
a to let in more light
b to allow the body to take in more oxygen
c to redirect blood to the areas that are involved in the panic response
d to increase blood flow
Answer:
Theres the answer.
Explanation:
The sympathetic division can be thought of in a general way as helping the body to mount a “fight or flight” response, with an overall increase in heart rate and blood pressure. Pressure increases because blood vessels constrict under sympathetic stimulation.

Answer:Soils' properties vary with the soil depth. The surface soil, or topsoil layer (O and A horizon in Figure 1–2), usually contains less clay, but more organic matter and air, than the lower soil layers. Topsoil is usually more fertile than the other layers and has the greatest concentration of plant roots.

When is now-casting used?
15 days from now
Severe Weather Events
Clear Sky Days
Sunny Days
Answer:
Severe Weather Events
Explanation:
JUST TOOK THE QUIZ
Now-casting is most commonly used during severe weather events to provide up-to-date information and warnings.
Now-casting is a type of short-term weather forecasting that focuses on the current and immediate future weather conditions, typically up to a few hours or a few days ahead. It is used to provide real-time updates and predictions for weather events that are occurring or expected to occur in the near term.
Now-casting is commonly employed during severe weather events such as thunderstorms, hurricanes, tornadoes, or heavy rainfall. It helps meteorologists monitor the current conditions, track the progression of the weather system, and issue timely warnings or advisories to the public.
While it may also be employed during clear sky days and sunny days, its focus is primarily on dynamic weather situations and short-term forecasts rather than stable weather patterns.
Therefore, now-casting is most commonly used during severe weather events to provide up-to-date information and warnings.

Answer:
Ecosystems have the potential to be sustainable over long periods of time. Something is sustainable if it can continue indefinitely depending on nothing but itself. The concept has become increasingly well-known as it has become evident that current human uses of resources, mostly fossil fuels, are unsustainable.
Explanation:

A region where the flora, fauna and microorganisms together with the abiotic factors live together is called an ecosystem.
The ecosystem has a flow of energy and nutrients. Ecosystems have the potential to sustain over a longer duration.
Sustainability is a source or resources that can be used indefinitely without compromising future needs.
The nutrient cycle of the ecosystem can be recycled but the energy flow of the system cannot be.
If the particular ecosystem can maintain its function and structure over some time will be sustainable.

A biology teacher placed a chicken egg in vinegar to dissolve the shell exposing the cell membrane. the teacher then placed the egg in a solution of sodium chloride in water in order to demonstrate cellular transport what type of cellular transport is the teacher demonstrating?
A. facilitated diffusion
B. active transport
C. filtration
D. Osmosis
I would assume osmosis, as sodium chloride is just salt and salt travels to water, which is abundant in the egg.
Option D. osmosis is the cellular transport is the teacher demonstrating in the given case.
Osmosis is the flow of water through a semi-permeable membrane from an area of higher water concentration to an area of lower water concentration. When the egg was placed in a solution of vinegar,
vinegar reacts with the eggshell, bubbles surround the egg and dissolve the shell.It is known vinegar is a weak acid diluted with lots of waterWater moves from the vinegar, through the egg’s semi-permeable membrane, into the egg due to osmosis.When the egg was placed in the salt solution that had a higher concentration of water than was inside the egg,
water moves into the egg.The egg will become larger when placed in the salt solution due to the solution’s low salt concentration and sinks in the solution.Thus, the correct answer is - option D. osmosis.

One of the primary problems in evolutionary biology has been how to maintain genetic diversity in qualities that are important for adaptation. Selection in diverse environments has been proposed as a means of facilitating the maintenance of genetic variation, taking into account the pattern of increasing genetic variation linked with environmental clines and heterogeneous habitats.
What is Genetic variation ?Genetic variation is the variance in DNA sequences among members of a population. Germ cells, such as sperm and eggs, as well as somatic (all other) cells, are prone to variation.
Examples of genetic variants that can exist in a human population include skin colour, hair colour, dimples, freckles, and blood type. The altered leaves of carnivorous plants and the evolution of flowers that resemble insects to entice pollinators are two examples of genetic variation in plants.Learn more about Genetic variation here:

Some cells have multiple dendrites and/or axons. What advantages does this have for the nervous tissue?
Answer:
It receives information from several cells.
Explanation:
The main advantage of cells having multiple dendrites and/or axons is that it receives information from several cells as compared to those cells which have one dendrite and receive information from only one cell. If neurons have hundreds or thousands of dendrites, so these dendrites allow the cell to receive information from thousands of other cells. So we can say that dendrites number plays a key role in nervous tissue.

how do enzymes play a factor into cellular respiration and photosynthesis? Name 2 instances where you use enzyme was inhibited/ plugged?
Answer: Enzymes are proteins that catalyze, or affect the rate, of chemical reactions without themselves being altered in the process. Specific enzymes catalyze each cellular reaction. The main role of enzymes during the respiration reaction is to assist in transferring electrons from one molecule to another.
There are two types of inhibitors; competitive and noncompetitive inhibitors. Competitive inhibitors bind to the active site of the enzyme and prevent substrate from binding.

lohmann, k. j. et al. regional magnetic fields as navigational markers for sea turtles. science 294, 364–366
The discussion of lohmann, k. j. et al. regional magnetic fields as navigational markers for sea turtles science 294, 364–366 is given in below paragraph-
Young loggerhead sea turtles (Caretta caretta) migrate across the North Atlantic Ocean from eastern Florida before making their way back to the North American coast. Here, we report that hatchling loggerhead turtles responded to magnetic fields by swimming in directions that would, in each case, help keep the turtles within the North Atlantic gyre currents and facilitate movement along the migratory pathway. These magnetic fields simulated those found in three widely separated oceanic regions. These findings suggest that juvenile loggerhead turtles have a navigational system whereby local magnetic fields serve as navigational markers and trigger changes in swimming direction at significant geographic borders.
What are magnetic fields?An electric charge, an electric current, and magnetic materials are all affected magnetically by a magnetic field, which is a vector field. A force perpendicular to the magnetic field and its own velocity acts on a moving charge in a magnetic field. The magnetic field of a permanent magnet attracts or repels other magnets and pulls on ferromagnetic materials like iron. A magnetic field that changes depending on the location will also exert a force on a variety of non-magnetic materials by influencing the mobility of their outer atomic electrons. By using electric currents, like those found in electromagnets, and by altering the electric fields over time, magnetic fields are produced that surround magnetized things.
