Bears and salmon have a predator-prey relationship. What would most likely happen to the bear population if the salmon population increased?
stay the same
decrease
increase
become extinct

Answers

Answer:

Increase

Explanation:

When there is enough food there is always excelling Reproduction

Bears and salmon have a predator-prey relationship, if the salmon population increased, it is most likely that the bear population would increase; that is the third option, as bears rely heavily on salmon.

What is the predator-prey relationship?

Bears are opportunistic feeders, and their diet varies according to what is available in their environment, and in areas where salmon is abundant, bears rely heavily on this food source to meet their nutritional needs. When salmon populations increase, there is a greater availability of food for bears, which can lead to improved body condition, increased survival rates, and higher reproductive success, and with more food available, female bears can produce larger litters of cubs.

Hence, bears and salmon have a predator-prey relationship, if the salmon population increased, it is most likely that the bear population would increase; that is the third option.

Take a look at the two boxes below. Each box has the same volume. If each ball has the same mass, which box 1 or 2 would weigh more? Why?

Answers

Answer:

Box 1.

Explanation:

The box 1 have the more mass because there are more number of balls present in the box while on the other hand, box 2 has less number of balls in the box. The volume of box boxes are the same as well as weight of the both boxes before placing of balls in it. Placing of balls changes the weight of both boxes because of the presence of different number of balls in each boxes that increases its weight.

a. The herbicide company lost its formula and started selling poor-quality herbicide.
b. Natural selection caused pigweed to mutate, creating a new triazine-resistant species
c. Triazine-resistant pigweed is more efficient at photosynthesis.
d. More triazine-resistant individuals survived each year, soi more individuals were triazine-resistant.
e. Some individuals acquired triazine resistance during their lifetimes, and were able to pass it on to offspring

Answers

Answer:

e. Some individuals acquired triazine resistance during their lifetimes, and were able to pass it on to offspring

Explanation:

The term resistance in the exposed example refers to an inheritable change in the weed population sensitivity, which is reflected in the consecutive failure of the chemical effects on the herb population.  

Herbicide might produce a genetic modification in the weed, leading individuals to survive under the effects of the chemical. The plants evolve with the capability of tolerating the chemical dose that is usually used to destroy a normal population of plagues.  

Resistance to the toxic is associated with mutations in some of the genes.

A mutation is a change in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.  

The selective pressure or modeling environmental factor is the triazine herbicide The weed´s response to herbicide is the survival of only those that carry mutations.  Natural selection benefits these mutations.  The mutated herbs survive, become more resistant, and pass the mutation to their offspring.

Describe a control for the above experiment. The factor, the presence of starch (if the process of photosynthesis has taken place or not) needs to be left out. How would you do this?​

Answers

Hi their here is the Answer

During photosynthesis a plant absorbs light energy using the pigment chlorophyll. This allows it to convert carbon dioxide and water into glucose. This glucose is:

transported to the growing parts of the plant for use in respiration
transformed into cellulose, proteins and oils
turned into starch for storage
Therefore, to test if a plant has been photosynthesising, you can test the leaf to see if starch is present.

Iodine solution is used to test leaves for the presence of starch. You need to:

heat a plant leaf in boiling water for 30 seconds (this kills the leaf, stopping any chemical reactions)
add the leaf to boiling ethanol in a water bath for a few minutes (the boiling ethanol dissolves the chlorophyll and removes the green colour from the leaf - it turns white so it is easy to see the change in colour)

wash with water to rehydrate and soften the leaf and spread onto a white tile
add iodine solution from a dropping pipette
After a few minutes, the parts of the leaf that contain starch turn the iodine from brown to blue/black.

The first trophic level is usually primary producers and herbivores are the primary consumers placed in the second trophic level.

There are some plants that depend on insects and small organisms for their nutrition.

Habitat is the living area of an organism it can be understood as address.

Biotic factors are the living organisms of the ecosystem while sunlight, soil, temperature are abiotic factors.

A food web is complex as it is made up of several food chains interconnected.

Normally there are only three or four trophic levels in most of the ecosystem.

In an experiment, two populations of one species of fruit flies were raised for several generations on different nutrients (starch and maltose). Then the members of the two populations were reintroduced and the mating frequencies of flies from the two different populations were recorded. Fruit flies fed on starch were more likely to mate with other starch fruit flies. The same was the case for maltose fruit flies. When they did mate, their offspring were infertile. The fruit flies are physically indistinguishable and genetically similar.

Match the characteristic with the correct species concept definition.

If you move a plant further and further away from a light source the level of O2 production would _______________ because the process of _____________________ slows and the process of _____________________ speeds up.

Answers

Answer:

1. Decrease

2. Photosynthesis

3. Cellular respiration

Explanation:

Photosynthesis in a plant requires light source to occur. The photosynthetic process gives oxygen gas (O2) as a waste product. This means that the production of oxygen is dependent on the intensity of light.

On the other hand, cellular respiration uses up or consumes oxygen in a plant. Hence, an increase in respiration reduces oxygen level if photosynthesis does not produce.

According to this question, If you move a plant further and further away from a light source, the level of O2 production would DECREASE because the process of PHOTOSYNTHESIS slows and the process of CELLULAR RESPIRATION speeds up.

Containers of ice cream are sold by volume, not by weight. Some ice cream manufacturers pump air into the ice cream before packaging it. Why does this practice make the ice cream more expensive to the consumer?

Answers

Ok so say a pint of ice cream is 7 dollars. And we have two different brands. Same price, same flavor, same package. One pint is filled to the top and is very dense. The other is filled an inch away from the top and is light and easy to scoop through. In processing they both were filled to the top but the lighter ice cream had air pumped into it. This air settles at the top as the air is less dense than the ice cream and still gets trapped in the ice cream as well. This costs the company nearly nothing to do and nearly doubled the mass of the ice cream in production. Leading to them saving a lot of money while charging the same price. Technically this brand is more expensive because you are getting less than what you are paying for.
