What happens when scientists turn off the gene that makes beaks in birds? A) birds have a large opening where the beak should be. B) Birds do not have any opening for their mouth. C) birds grow mouths with teeth that resemble alligator teeth. D) the birds grow mouths without any teeth.
Answer:
A) birds have a large opening where the beak should be.
Explanation:
when scientists turn off the gene that makes beaks in birds, the birds have a mouth where no teeth are present. The birds have mouth because the bird resembles and closely related to the dinosaur. There are some proteins that is responsible for the occurrence of beak but when the genes are turn off these protein stop producing that leads to turn the beak place into mouth.

Question 7 of 10
The brain's complexity arises from the:
A. communication between the hind-, mid-, and forebrain.
B. functions of individual neurons.
C. division between two halves of the cerebral cortex.
D. complex connections of simple pieces.
SUBMIT
The complexity originates from the interaction of several neural circuits that operate across temporal and spatial scales, allowing the brain to adapt to a changing environment and conduct high-level mental activities. Therefore, option (D) is correct.
What is the complexity of the brain?The human brain is an intricate system that operates on multiple temporal and geographic scales, and it is this complexity that gives rise to the intricate molecular, cellular, and neuronal events that, when taken as a whole, constitute the physical and biological foundation of cognition.
This complexity is the result of the interaction of a large number of neuronal circuits that function over a diverse range of temporal and spatial scales. This interaction enables the brain to adapt to an environment that is constantly changing and to perform a variety of high-level mental functions.
Therefore, complex connections of simple pieces leads to complexity.

What is one use of hydrogen?
Answer:
early all of the hydrogen consumed in the United States is used by industry for refining petroleum, treating metals, producing fertilizer, and processing foods. U.S. petroleum refineries use hydrogen to lower the sulfur content of fuels.
Explanation:
Answer:
However, hydrogen is useful as an energy source/fuel because it has a high energy content per unit of weight, which is why it is used as a rocket fuel and in fuel cells to produce electricity on some spacecraft. Hydrogen is not widely used as a fuel now, but it has the potential for greater use in the future. So there you have it!

The correct answer is - Biotic factors are any living factors and abiotic factors are anything non-living in an ecosystem.
Explanation:
An ecosystem consists of all living organisms, non-living organisms that are present in a physical environment in a particular geographical area. The physical environment consists of several factors such as landscape, pH, climate, salinity, and other factors that represent abiotic factors.
Any living organism present in an ecosystem is biotic factor Examples of biotic factors include are mammals, birds, trees, microbes, grasses, fish, bacteria, and many more.

Which of the following would MOST LIKELY result in decreasing carbon dioxide levels in a lake?
A) an increase in the amount of precipitation
B) a decrease in competition among producers
C) an increase in the number of fish caught from the lake
D) a decrease in the amount of sedimentation entering the lake
Answer: C: an increase in the number of fish caught from the lake
Explanation:
An increase in the number of fish caught from the lake would most likely result in decreasing carbon dioxide levels in the lake. Therefore, option C is correct.
What are the effects of carbon dioxide in a lake?Carbon dioxide can have both direct and indirect effects on a lake's ecosystem. Here are some of the effects:
Acidification: When carbon dioxide dissolves in water, it forms carbonic acid, which can lower the pH of the water.
Oxygen depletion: If carbon dioxide levels are too high, it can lead to oxygen depletion in the water.
Algal blooms: High levels of carbon dioxide can also stimulate the growth of algae in the water. This can result in algal blooms, which can have negative effects on the lake ecosystem, such as oxygen depletion, fish kills, and changes in water clarity.
Thus, an increase in the number of fish caught from the lake would most likely result in decreasing carbon dioxide levels in the lake. Therefore, option C is correct.
