The idea that the brain of an infant is like a blank slate is known as: ____
a- tabula rasa
b-dry cup
c-cogito ergo sum
d-the empty brain
Answer:
a
Explanation:
The idea that the brain of an infant is like a blank slate is known as Tabula rasa. It is given in Locke's philosophy. Thus, the correct option is A.
What is Tabula rasa?Tabula rasa is the theory which describes that individuals are born without a built-in mental content, and therefore all the knowledge comes from experience or perception in life. The epistemological proponents of the tabula rasa disagree with the doctrine of innatism, that holds the fact that the mind is born already in possession of certain knowledge eithout experience.
In Locke's philosophy, tabula rasa was the theory that at birth the infant mind is a blank slate without rules for processing data, and the data is added and rules for processing are formed solely by one's sensory experiences in life.
Therefore, the correct option is A.

Match each graph with its correlation coefficient.
+1.0
+0.85
+0.15
-0.50
-1.0
Answer:
-0.50
Explanation:
For the graph displayed, the most probable value of the correlation Coefficient is - 0.50 ; the line of best fit has a negative skoe and hence will have a negative relationship as the correlation Coefficient is a statistical value which measures the degree of relationship between two variables. Also, the distribution of data in the plot does not give a perfect fit, hence a correlation Coefficient of - 1.0 isn't possible for the distribution shown.
Answer:
fist graph: -0.50
second graph: +0.85
third graph: +0.15
fourth graph: +1.0

Will give brainliest
Answer:
C, D, E. F
Explanation:
My best guess...
The pH of a solution is a measure of how acidic or basic it is. The greater the pH, the more basic the solution is. Corals and other marine invertebrates require less energy to make their exoskeletons and shells when ocean water is slightly basic. As carbon dioxide concentrations in Earth’s atmosphere rise, ocean water absorbs carbon dioxide and becomes more acidic. This process is called ocean acidification. How do you think ocean acidification will affect the coral reef?
Explanation:
Because coral reefs have limestone (calcium carbonate), the coral reefs will be greatly affected. The increase in hydrogen ions in the ocean will corrode the coral reef, making it inhabitable for species. This will affect the crabs that get their food and the community that lives within in it. Making countless of species to loose their lives and their way if living.

Forest A
Forest B
Two forest communities are shown here at different stages of succession. The different plant species and their relative abundance are
indicated by the diagrams. Researchers find that rodent populations are more abundant in forest A while deer populations are more
abundant in forest B. What describes the difference in the populations observed by the researchers?
es ))
A)
Forest A has is in an earlier stage of succession and does not have as many
mature trees upon which deer feed.
B)
Forest B lacks grasses due to lower light levels at the ground, removing a
species that is toxic to most deer populations.
0)
Forest B lacks the canopy closure required for protection of rodents from
predators, which decreases the rodent populations.
D)
Forest A is at a later stage of succession, allowing for more rodents to
migrate into the area and be found at a higher abundance.
Answer:
a, forest a is correct answer
