Answer: Echidnas: With a keen sense of smell, an echidna uses its long, hairless snout to search for food, detect danger and locate other echidnas. Termites are the preferred food, which is why the animal is often called the 'spiny anteater'. After finding food, an echidna catches the prey with its long, sticky tongue
Crocodiles: Crocodiles are mostly nocturnal animals. They are predators and spend most of their time in the water; although they are also known to make journeys of several kilometres over land. ... Crocodiles capture water animals in their jaws with a sideways movement of the muzzle
Explanation:
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
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).

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.
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.

The most basic concepts of cell theory are that cells are the basic units of life and that all living things are made of cells.
Which answer correctly explains why these concepts are the basis of a theory and not a hypothesis? (5 points)
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.
Answer:
Cell theory explains how cells function rather than predicting how they function.

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.
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"

How is editing the genetic code different from artificial selection?
Answer:
Editing genetic code is when you take something already born and editing its dna. Artificial selection is when you edit somethings dna before it's born.
Editing genetic code creates new trait in the species but artificial selection select the trait already present in the species.
What are genetic code editing and artificial selection?Humans can transform a species' members through genetic engineering and artificial selection to make them better suited to human demands. The method for transformation, however, is distinct.
Artificial selection selects for existing qualities in a species, whereas genetic engineering develops new traits. Following the cutting of the DNA, researchers employ the cell's own DNA repair mechanism to add or remove fragments of genetic information.
Artificial selection differs from natural selection in that it refers to selection used by people to generate genetic change. When artificial selection is used, the characteristics or traits are modified.
Therefore artificial selection selects species having new traits already present and genetic code editing creates new traits.
