Answer:
The activity of Bromine will reduce
Explanation:
Bromine is found in pineapple stem with pH range of 3.5- 5.2 this implies that the environment where bromine is found is acidic hence when taken to a product whose pH is 11 which is basic then its performance will be low because its can only function well in an acidic medium.
pH ranges tell whether a substance is acidic, basic or neural.
Acid range from 3.5-6
7- neutral
8 above is basic
This is about knowing the behaviour of some elements in different PH Values.
The activity of bromelain will decrease in a product with a pH of 11. .
We are told that the PH of pineapple fruit is of the range of 3.5 - 5.2. In reality, this also includes it's stems and the plants as well. This falls into the acidic range because PH less than 7 is acidic.Now, these stems, plants and fruits of pineapple usually contain bromelain. This implies that bromelain does its' work in an acidic environment since pineapple has an acidic PH.If bromelain is used in a product with a PH of 11, it means it is being used in a basic environment because a PH greater than 7 indicates a basic nature. This means bromelain will not function as well as it did in the acidic environment and as such the activity of bromelain here would decrease.We can now conclude that the activity of bromelain will decrease in a product that has a PH of 11.

The southern pine bark beetle lives in the bark of pine trees. The beetles feed on the tree and live within the bark of the tree, producing offspring. Once the beetles have infested a tree, they will spread to other trees in the same area. Eventually a pine tree infested by the beetle will die. The population of pine bark beetles can be expected to increase in a new habitat where it is introduced. The population would NOT be expected to decrease until what happens?
Answer:
The beetle population would NOT be expected to decrease until pine population decreases in size.
Explanation:
The southern pine bark beetle is responsible for some of the most important pine forests loss in the last forty years. The insect identifies a pine of a certain advanced age and digs a hole in the bark to establish in places were sugars and starch circulate. There it lays its eggs and feeds. When larvae feed, they introduce a fungus that interrupts water and nutrients circulation between roots and leaves, causing the pine death. When the pine is completely infested or is dead, the insects move to another pine, dispersing and increasing the population size.
As the beetle population size increases, the pine population decreases, after being killed by the insects. When a pine dies, it not only stops producing food for the beetles but it also becomes susceptible to being inhabited by other species that might be predators of these beetles.
The beetles' population starts to decrease when most of the pines in the forest are dying. They hardly have available food and they are more exposed to being eaten by their predators.
The beetle population would NOT be expected to decrease until the pine population decreases in size.
It is the cycle of predator-prey, where predators population affect the dinatic of prey population, and viceversa. Populations sizes increase and decrease in these cycles. Herbivory is a kind of predation, in which the prey is a plant. In this example, the predator is the beetle and the prey in the pine.
Explain why overpopulation occurs and how it impacts ecosystems.

i hope it is right if not sorry!!!!!!!!!!!!!!!!!!!!!
Answer:
Aquaculture means to foster organisms (for the most part fish) that live in water.
Explanation:
After reading Holt Enviromental Science's Food and Agricultural Section: Animals and Agriculture passage, you can define aquaculture. In the passage it reads "fish farms generally consist of many individual ponds that each contain fish at a specific stage of development." The fish grow until they are matured and then "they are harvested."

Over time, what happens to a trait that is an advantage to an organism?
When the motion energy of an object changes, there is inevitably some other change in energy at the same time. If
an object is slowing down, where is the energy going? (Check all that apply)
The potential energy could be increasing, like a ball thrown into the air.
The kinetic energy could be lost to friction or airfmsistance.
The ball could be returning to its natural resting state.
Due to the conservation of energy, the kinetic energy must stay the same.
Please help
When the motion energy of an object changes, there is inevitably some other change in energy at the same time. If the object is slowing down, where is the energy going?
1. The potential would increase since when the ball is slowing down, its kinetic energy is being transformed into potential energy and when the ball gets hit or kicked again, it releases the potential energy and it transforms into kinetic energy.
2. The kinetic energy wouldn't exactly be lost to friction or air resistance, it's merely being converted into potential energy when the ball is slowing down due to those factors.
3. The ball returning to its natural resting state is correct since according to Newton's 1st Law in which an object that is at rest or is moving will not change unless there is another force acting upon it. in this case, the ball was kicked and there are other forces acting upon it like friction and air resistance, those factors cause the ball to slow down. Eventually the ball will stop and return to its original resting state.
4. This one is incorrect since kinetic energy is not staying the same as the person or any other force that is exerted on it be increased therefore increasing the kinetic energy.

How is the epithelium suited for the substances ?
Answer:
Epithelial tissue is composed of cells laid together in sheets with the cells tightly connected to one another. Epithelial layers are avascular, but innervated.
Epithelial cells have two surfaces that differ in both structure and function.
The epithelial cells are nourished by substances diffusing from blood vessels in the underlying connective tissue. One side of the epithelial cell is oriented towards the surface of the tissue, body cavity, or external environment and the other surface is joined to a basement membrane. The basement layer is non-cellular in nature and helps to cement the epithelial tissue to the underlying structures.

Each spring when the worms reproduce, they have about 500 babies BUT only 100 of these 500 ever become old enough to reproduce. Question: What are the worms using to try to get as many of their offspring to survive? *
Answer:
If the environmental condition are suitable, the worms reproduce rapidly.
Explanation:
Environmental condition such as temperature, humidity, pH and texture of the soil has a great influence on the population of worms. If these environmental conditions are optimum, the worms reproduce rapidly and increase in population occurs. The population of worm increases because more worms start reproduction and reproduce baby worms. With the passage of time, these baby worms fully matured and start reproduction and increase the population of worms.
Answer: The keep themselves away from predation
Explanation:
The worms are mostly kept away from predators to make them survive. Some worms can be nocturnal while some are diurnal the nocturnal worm are inactive during the day keeping them away from predator but diurnal worms moves around during the day and it exposes them to predation they are been lost. The population the are survived to adult are the ones that have selective advantage of not being destroyed or feed on by preys. The Nocturnal are able to survive over a long time
