Which kind of force do you exert on an object when you pull it toward you?
A applied force

B.
attractive force

c. drag force

D
normal force

Answers

Answer:

I would say B is the answer.

Explanation:

An applied force is a force that is applied to an object by a person or another object. Example: pushing a box to the other side of a room.

A normal force is a force that surfaces exert to prevent solid objects from passing through each other. Example: resting a book upon a table.

Drag is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This doesn't really match the force we use.

However, an attractive force is a force by which one object attracts another. Example: two magnets pulling/colliding together. This is a good example of a force we exert on objects when it is pulled toward us.

Plants lose __ % water to transpiration resulting in 10% increase in atmospheric water vapor which increases relative humidity and chance of precipitation.

A: 90
B: 10
C: 100
D: 45​

Answers

Answer: A

Explanation: Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem. Transpiration is caused by the evaporation of water at the leaf–atmosphere interface. Up to 90 percent of the water taken up by roots may be lost through transpiration as only a small amount of that water is used for growth and metabolism.

Associate specific relationships between science and/or technology and human population growth.

Answers

The relationship between population growth and technological change has been debated since the end of the eighteenth century a debate whose main configuration has proved remarkably persistent. During the ensuing 200 years, historically unprecedented rates of change have been observed in both variables: in industrial, commercial, and communications revolutions spreading out from Europe, North America, and Japan; in parallel (though spatially and temporally uneven) revolutions in the technological base of agricultural production; and in a demographic transition–in which mortality decreased and fertility first increased, then decreased that is still underway in many developing countries. Interconnections there must be, yet the attribution of primacy and direction of causation among these variables, not to mention the nature of the mechanisms involved and means of influencing outcomes in the interest of meeting social goals, remain controversial. Meanwhile, a new awareness of the emergence of complex social-environmental systems, whether at local or global levels, has extended the debate beyond the discipline of economics, and broadened its emphasis from the welfare of the human race to that of the planet.

There are 100 ants in an ant farm that is 10 inches by 5 inches. What is the population 1 density? (Show your work)​

Answers

The population density would be 2 ants/square inch

Population density is defined as the population size of a species of organism per unit area of the habitat occupied.

In this case, the population size of ants in the ant farm is 100 while the dimension of the ant farm is 10 inches by 5 inches.

Area of the ant farm = Length x breadth

                                   = 10 x 5

                                   = 50 square inch

Population density of ant = population size/area

                                           = 100/50

                                           = 2 ants/square inch

What can you infer about the position of the galaxies 100 million years
before this telescope photo was taken? How does this relate to the big bang
theory?

Answers

Although the picture for this question is not given, if we have the possibility to view galaxies from 100 million years ago and compare them to the photos we have today, we would see that their positions would be different.

Why would the position of the galaxies have changed?

This has to do with the fact that the universe is always expanding.

The idea of an expanding universe means that galaxies are moving farther away all the time.

However, due to the effects of gravity, some galaxies pull each other in and form groups or clusters.

Therefore, due to the formation of galaxy groups or clusters, the position of galaxies may have changed in relation to others from outside its groups in the last 100 million years, while remaining the same relative to other galaxies in its local group.

above?
A. Point A
B. Point D
C. Point B
D. Point C

Answers

Answer: the correct answer is D

Explanation:Carrying capacity is characterized as the maximum populace size that a domain can continue inconclusively.  For most species, there are four factors that factor into figuring the carrying capacity of an individual population: food accessibility, water resources, habitat, and ecological conditions.

In a graph representation of population size in a time period increases until it reaches carrying capacity, carrying capacity is representing in the graph where the increase in curve becomes stable and makes a plateau.

This model chose to include certain features and exclude other features. For example, this simulation only includes rabbits, wolves, and grass but there are other predators of rabbits and other food sources for rabbits. Why do you think the creators focused on these data elements and not others

Answers

The creator focused on these data elements and not others because he was trying to create a food chain instead of a food web.

In the ecosystem, the living and non-living things interact over time leading to exchange of energy.

A food chain can be defined as the steps through which energy transfer occurs in an ecosystem.

The energy flows from the producers (grass), primary consumers, (rabbits) and then the secondary consumers (wolves).

The energy flow is indicated with an arrow thus,

grass ---> rabbit -----> wolves.

Food chain, therefore includes linear sequence of organisms.

Food web on the other hand illustrates a complex feeding relationship within the ecosystem.

The food web is made up of a prey that can be eaten by more than one predator.

Therefore, even though there where other predators of rabbits and other food sources for rabbits, he chose only few features to create a food chain.

Vegetative propagation

Cutting is a form of vegetative propagation attribute of some organisms.

Cutting a tissue off a plant and the tissue developing its own root to become a new plant happens by mitosis.

Mitotic division of the cut tissues leads to the formation of roots and the eventual growth to a new plant.

Mitotic growth means that the new plant will be genetically and physically identical to the parent plant, provided they grow under the same conditions.
