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?
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.

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
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.

Why is a female skeleton smaller, and not as wide a male skeleton?
Can someone please explain?
Answer:
A male's skeleton is usually thicker, rougher and appears more bumpy. ○ Due to the fact that males have larger muscles and therefore their skeletons require stronger attachment sites. Women who have borne children have scars on the surface of their pelvis. The femur (thigh bone) of a male is thicker than a females.

Transpiration pull will be stronger on a hot, humid day more than on a hot
dry day.
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.
Group of answer choices
hybrids are fertile
[ Choose ] biological ecological morphological phylogenetic
physiologically similar
[ Choose ] biological ecological morphological phylogenetic
genetically similar

Answer:
Hybrids are fertile --- biological concept.
Physiologically similar ---- morphological concept
Genetically similar ---- phylogenetic concept
Feed on starch or maltose ---- ecological concept.
Explanation:
Hybrids are fertile is a biological characteristics of an organism, physiologically similar is a morphological characteristic of a specie, genetically similar is a phylogenetic characteristic of a specie and feed on starch or maltose is a ecological characteristic of an organism. The ability of two individuals to successfully produce fertile offspring is biological species concept whether individuals look similar is a morphological species concept closely related individuals are evolutionarily or phylogenetic species concept.

Answer:
Pumas, lobos y coyotes, águilas, serpientes, halcones, búhos y perros.
Explicación:
Pumas, lobos y coyotes, águilas, serpientes, halcones, búhos y perros son los animales que matan al gato y se alimentan de ellos. Estos organismos son los depredadores de los gatos y dependen del gato y de algunas otras especies para cumplir con su requerimiento de alimento. Algunos animales matan directamente al gato a través de sus dientes fuertes, mientras que otros matan al gato a través del veneno que está presente en su boca.

Answer:
The correct answer is -
26. false
27. true
28. false
29. false
30. true
31. true
32. false
Explanation:
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.
Energy is not recycled in ecosystems like water or carbon.

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.
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.

A farmer uses triazine herbicide to control pigweed in his field. For the first few years, the triazine works well and almost all the pigweed dies; but after several years, the farmer sees more and more pigweed. Which of these explanations BEST describes this observation?
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
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?
