Answer:
A science teacher asked students to describe and explain an internal adaptation that allows for a specific function. Students wrote the following:
Student 1: Leaf frogs can change their appearance to match their surroundings.
Student 2: Birds have hollow bones, enabling them to fly.
Student 3: Penguins live together in groups.
Student 4: Musk ox have thick, shaggy hair to protect them from cold temperatures.
Which student’s answer describes and explains an internal adaptation that allows for a specific function?
Explanation:
As internal adaptation refers to anatomical adaptation so correct option is B - Student 2: Birds have hollow bones, enabling them to fly.
The bones of birds have hole openings inside. Therefore, chicken bones are much less dense than human bones. These hole areas purpose the chicken to have lighter mass, permitting a less difficult raise for flight. Birds additionally have air sacs which can be extensions of their lungs. Hollow bones also are referred to as pneumatized bones, which means they may be full of areas for air. It is the notion that this shape allows for oxygen consumption throughout the flight. Air sacs are connected to the hole regions in a chicken's bones.What is the use of feathers?Birds have feathers that assist them to fly. The lengthy flight feathers at the wings and tail assist birds' stability and steering. In addition, birds have a device of air sacs of their frame that hook up with the lungs. The air sacs permit birds to extract plenty greater oxygen from every breath of air than different animals can.
Thu it is clear that birds have hollow bones, enabling them to fly is an internal adaptation.

Bird guides once listed the myrtle warbler and Audubon's warbler as distinct species because of differences in color patterns of the feathers and size of the beak. Recently these birds have been reclassified as eastern and western forms of a single species, the yellow-rumped warbler, based on the observation that the two forms interbreed often in nature and the offspring have good survival and reproduction. The earlier classification into two species was using a species concept; the reclassification is using the species concept. _________
Answer:
morphological; biological
Explanation:
The morphological species concept highlights the importance of physical traits to delimit species. This concept is useful for classifying asexually-reproducing organisms and where lack information on interbreeding (for example, to classify fossils). On the other hand, the biological species concept states that one species represent a group of organisms that can interbreed (or potentially can interbreed) in order to produce fertile offspring. The biological species concept is nowadays the most widely accepted concept to define species.
Food and territory are balancing
factors in an ecosystem. What type
of phenomena balance these
factors?
A. anthropogenic
B. unnatural
C. natural
D. reproductive
Answer:
The correct answer is C. Natural phenomena.
Explanation:
Food and territory are two factors that clearly influence the development of life within an ecosystem: the abundance or lack of these factors will clearly be decisive in the normal development of life within the ecosystem, that is, the greater the territory and food, the better the quality of life of the living beings in said ecosystem.
In turn, food and territory are affected by various natural phenomena, which condition the abundance or lack of these factors: thus, phenomena such as earthquakes, floods, fires, etc., cause the territory and food to fluctuate as soon as to their quantities.
Answer:
C. natural
Explanation:

Joseph sets up an experiment growing corn in three containers. Each container has the same amount of
potting soil and fertilizer. Each corn plant is five centimeters (cm) tall. The containers are all placed so thatthey
receive the same amount of light. All of the plants are grown at the same temperature. The plants are
watered once a week: container #1 receives 10 ml of water, container #2 receives 20 ml of water, and
container #3 receives 30 ml of water. Joseph measures the growth of each plant for six weeks.
Which hypothesis is being tested?
The amount of water supplied will affect plant growth.
The temperature will affect plant growth.
The type of fertilizer will affect plant growth.
The amount of light exposure will affect plant growth.
Answer:
The amount of water supplied will affect plant growth is the hypothesis being tested.
Explanation:
Because that is the only variable being altered or changed, every other variable remains consistent. In any experiment what your testing is what's altered between each subject or test group.

Good morning guys , I have a question : why is height not controlled by one gene ?
Answer:
Because the gene is an inheritance of our ancestors, weight is something you gain or lose depending on how balance your health is. The reason why our weight can't be controlled by the gene is because the gene has different traits coming from each parents(50%) and grandparents(25%), and either parents has different weight, so it will be hard for the gene to capture one specific weight from both sides.
Answer:
Height and other similar features are controlled not just by one gene, but rather, by multiple (often many) genes that each make a small contribution to the overall outcome. This inheritance pattern is sometimes called polygenic inheritance
