Ronald observes a sparrow's nest in a shrub outside his home. The table below describes his findings.
Week
Observations
1
Six eggs were laid in the nest.
3
Five eggs hatched, and one egg did not hatch.
One of the chicks disappeared.
7
Three of the chicks learned to fly, and another one disappeared.
What part of natural selection did Ronald observe?
adaptation
overproduction
selection
variation
Answers
Answer:
B. Overproduction
Explanation:
Overproduction is one of the main part of natural selection whereby an organism reproduces more offspring, of which only a few would be able to survive given the environmental condition amd factors that would be against the survival of the offspring to maturity.
From Ronald observation, we can see that the bird produces more eggs than would survive. Only 3 of the chicks survived.

Answers
Answer:
oceanic vocanoes
Explanation:
The continental drift is an idea that the continents can move. Alfred wegner in his evidence of this phenomenon used the following hypothesis:
Rocks of same age and type formed side by side and these rocks drifted apart to separate continents. Also as continents drifted apart mountain ranges separated.Alfred used movements from ancient glaciers as evidence, Fossils of dead plants and ancient animals also served as evidence. The fossils of these plants and animals were found on land areas that are now far apart. Wegner concluded that the continental drift was what separated the remains of these fossils.All of the above was used as evidence. What was not used as hypothesis by Wegner was oceanic volcanoes
Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Grooves.

Explanation:
did the quich check
The statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.
Taxonomy is a field of study focused on naming and classifying groups of organisms according to their morphological and genetic features. The taxonomic system organizes species from larger to more specific taxonomic categories in a hierarchical system.The botanical taxonomist Carolus Linnaeus is considered the father of taxonomy because he was the first person to formulate a system for classifying different species of plants and animals.Nowadays, the taxonomic system includes eight (8) categories from larger to more specific: domain, kingdom, phylum, class, order, family, genus, and species.In conclusion, the statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.

Your body uses feedback mechanisms to help maintain a stable internal environment called homeostasis. Changes can come from outside or inside the body and the body must respond to these adverse changes to return to a steady state. One such example is what happens when you go for a run on a hot summer day and your body temperature increases. According to the diagram, one of the mechanisms used to cool down is vasodilation. Similar mechanisms are also used when your body temperature drops due to a cold environment. Which of these would NOT help return a body to homeostasis by increasing body temperature?
A) shivering
B) vasoconstriction
C) muscles contract
D) increasing blood pressure
Answers
Answer:
Option D increasing blood pressure.
Explanation:
Increasing blood pressure
What is feedback mechanism in homeostasis?
Homeostasis is generally maintained by a negative feedback loop that includes a stimulus , sensor , control center , and effector . Negative feedback serves to reduce an excessive response and to keep a variable within the normal range.
What are the two feedback mechanisms which work to maintain homeostasis?
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

PHET Energy Skate Park Simulation .Consider this equation: gravitational potential energy = mgh. Which of those variables is changing as the skater moves up and down the track?
Answers
Answer:
h - height
Explanation:
gravitational potential energy = m * g * h
m stands for mass. Mass doesn't change in physics
g stands for gravitational acceleration. It is a constant.
h stands for height. When the skater moves up and down the track the height from the ground changes. Therefore this variable does change.
In the equation gravitational potential energy = mgh, the variable that is changing as the skater moves up and down the track is the variable h, which represents the height or vertical position of the skater.
As the skater moves up the track, the height increases, resulting in a higher value for h. Conversely, as the skater moves down the track, the height decreases, leading to a lower value for h.
The other variables in the equation, m (mass) and g (acceleration due to gravity), typically remain constant unless specified otherwise. Therefore, the changing variable in this equation as the skater moves up and down the track is the height (h).

Answer:
chemical
Explanation:
Respiration is a redox reaction on which sugar is oxidized to produce energy .
What is respiration?Cellular respiration is a sequence of chemical events that break down glucose to produce ATP, which can then be utilized as energy to power a variety of reactions throughout the body. Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration.
Animals and humans use breathing to get the oxygen they need for cellular respiration. In order to create ATP, the nutrients you absorb through food must be broken down by the oxygen you breathe, while carbon dioxide and water are generated as waste products.
