How did kettlewell determine if moths lived longer than others?.
Answer:
He placed light and dark moths on tree trunks where he could observe them and then he recorded the times a bird found the moth.
Explanation:
How did Kettlewell determine if moths lived longer than others? By monitoring the amount of dark and light-colored moths on the light and dark trees and seeing how many were caught by birds
Kettlewell determines if moths lived longer than others through the fact that it considerably analyzes the amount of dark and light-colored moths on the light and dark trees and observes the number of many that were caught by birds.
How did Dr. Kettlewell determine the fact?Dr. Kettlewell test his hypothesis of the evolutionary mechanism of industrial melanism, he directly studied bird predation on moths. Kettlewell placed light and dark moths on the trunks of trees from where they can be observed. Then the number of times a bird found the moth on the tree trunk was calculated.
According to the question, he recorded the times a bird found the moth. He found that on dark tree trunks, birds were twice as likely to eat a light moth as a dark moth. The same birds would find the dark moth twice as often if the bark on the tree was light.
This supported the idea that dark moths had a survival advantage in a dark forest. He placed light and dark moths on tree trunks where he could observe them and then he recorded the times a bird found the moth at a given place.

Answer:

Explanation:
trust me bro
In a pedigree, an affected male would be designated by a shaded square. The correct answer is option 3.
A pedigree is a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors from one generation to the next.
In a pedigree, an affected male would be designated by a shaded square. This is because squares represent males in a pedigree, and shading indicates that the individual is affected by the trait being studied. In contrast, an open square would represent an unaffected male. Similarly, a shaded circle would represent an affected female, while an open circle would represent an unaffected female.
Therefore, a pedigree would show a shaded square for an affected man. Option 3 is the right answer.

Why is ocean acidification important to us?
What will happen to the pH of the water when CO2 is added?
What does the abbreviation “pH” stand for?( briefly explain)
#1
Ocean acidification is harmful for aquatic ecosystemThis is being reason for death of many aquatic creatures#2
CO_2 will form carbonic acid which is acidic in nature
So it will decrease the pH#3
PH stands for potential of Hydrogen .
If pH is less than 7 it's acidic and if greater than 7 it's basicExplanation:
Acidification reduces the availability of carbonate ions in ocean water, which provide the building blocks these organisms need to make their shells and skeletons, significantly reducing the chances for their offspring to survive.
when carbon dioxide is dissolved in water, the release of hydrogen ions in carbonic acid is what lowers the pH. As CO2 levels increase around Earth, the amount of dissolved CO2 also increases, which increases the amount of carbonic acid, therefore decreasing the pH.
pH stands for "power of hydrogen." The "H" is capitalized because it is the hydrogen element symbol. pH is a measure of how acidic or basic an aqueous solution is. It is calculated as the negative logarithm of hydrogen ion concentration.

Plants, like animals and other organisms, must adapt to their changing environments. While animals are able to relocate from one place to another when environmental conditions become unfavorable, plants are unable to do the same. Plants must deal with changes in their environment in a different way. Plant tropisms are mechanisms plants use to respond to their environment. A tropism is a growth toward or away from a stimulus. Common stimuli that influence plant growth include light, gravity, water, and touch. Evaluate each of the tropisms. Select ALL of the choices that correctly pairs the type of tropism with its environmental stimulus.
A) phototropism: growth toward light
B) hydrotropism: growth in response to water
C) thigmotropism: growth in response to touch
D) geotropism: growth in response to soil conditions
E) thermotropism: growth in response to temperature
Answer:
A,B,C, and D
Explanation:
Forms of tropism include phototropism (response to light), geotropism(response to gravity), chemotropism (response to particular substances), hydrotropism (response to water), thigmotropism (response to mechanical stimulation), traumatotropism (response to wound lesion), and galvanotropism, or electrotropism (response to electric current).
