1. A worker uses a board that is 4 m long to pry up a boulder. A small rock is used for a
fulcrum and is placed 0.5 m from the resistance end of the lever. Calculate the MA of the
I
board.

Answers

Answer:

7

Explanation:

Mechanical advantage is given by the ratio of the distance of the fulcrum from the two objects of the system.

Here the boulder is [tex]0.5\ \text{m}[/tex] from the fulcrum and the mass at the other end of the lever is [tex]4-0.5=3.5\ \text{m}[/tex] from the fulcrum.

So, mechanical advantage is given by

[tex]MA=\dfrac{3.5}{0.5}\\\Rightarrow MA=7[/tex]

So, mechanical advantage of the board is 7.

Cell theory explains how cells function rather than predicting how they function.
Cell theory has been unchanged for many decades and as a result can be accepted as fact.
Cell theory is a prediction based on observation and not a fully accepted idea.
Cell theory remains largely untested rather than being subject to testing.

planets.

C) The inner planets are hotter and relatively larger in size when compared to outer planets.

Which statement is FALSE? A. Phototropism and geotropism are adaptations of plants that allow for survival. B. Tropism is the growth response of plants to their environment due to external stimuli. C. A plant's response to moonlight is phototropism while it's response to gravity is geotropism. D. A tropism that causes a plant to grow towards the stimulus is positive.

Answers

Answer:

A. Phototropism and geotropism are adaptations of plants that allow for survival.

Explanation:

Ideally, TROPISM is the growth response of plants to their environment due to external stimuli as rightly stated in this question. However, based on what stimulus the plant is responding to, there are different types of stimulus.

Phototropism (photo-light) is the response of an organism to a light source while Geotropism (geo- gravity) is the response of an organism to gravity. Hence, based on this question, a plant's response to moonlight is phototropism while it's response to gravity is geotropism.

Also, tropism can either be positive or negative depending on whether the response is towards the stimulus (positive) or away from the stimulus (negative). Therefore, the FALSE statement is "Phototropism and geotropism are adaptations of plants that allow for survival"

For which method of determining population size is the population not aware of the sampler’s presence?

a. mark/recapture
b. direct observation
c. sampling
d. indirect observation

Answers

Answer:

The method of determining population size is the population not aware of the sampler’s presence is indirect observation.

D

The method in which the population is not aware of the sampler's presence is indirect observation (Option d).

Indirect observation refers to the collection of information obtained by other researchers in order to record it in specific informative materials (e.g., books, review/research papers, videos, etc.).

An example of indirect observation can be the record in a book of specific animal behaviors (e.g., the presence of marks on the ground).

In conclusion, the method in which the population is not aware of the sampler's presence is indirect observation (Option d).
