Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels.
Answer:
By breathing.
Explanation:
Humans inhale oxygen, and when they need to release it, (exhale) that oxygen is no longer oxygen and is now carbon dioxide. Trees and plants are what helps oxygen to exist in our world even though we breathe it in and convert it to carbon dioxide. Hope this helps ^^
Leaves are modified as tendrils for climbing as in

d)Bougainvillea
Answer: pea
Explanation:
In the garden pea, it is only the terminal leaflets that are modified to become tendrils. In other plants such as the yellow vetch (Lathyrus aphaca), the whole leaf is modified to become tendrils while the stipules become enlarged and carry out photosynthesis.
H-E-L-P! ASAP! Describe two ways that plants respond to their environment, giving an example of each. Your answer can include ways that plants respond to seasonal changes, light, gravity, or touch.
Plants have evolved to respond to critical changes in the environment by either growing their roots, or leaves towards/away from any stimulus. This response, is called a tropism.
For example, The plant's stem and leaves bend toward sunlight. Their roots grow toward Earth's gravity.
Plants have complicated systems to detect and then respond to changes in light, gravity, temperature, and or even physical touch.

how will climate change affect the habitat distribution for the baltimore oriole?
Climate change has a great effect on the habitat distribution of Baltimore orioles bird.
Climate change will adversely affected the habitat distribution of Baltimore orioles because climate change causes heat waves, wildfires and intense downpours which is harmful for Baltimore orioles.
The climate changes will limit the populations of ranges of Baltimore oriole as well as changes the habitat. These Baltimore orioles moved to other places where the climate is favourable so we can conclude that climate change has a great effect on the habitat distribution of Baltimore orioles bird.

Which organism carries out autotrophic nutrition
Answer:
Autotrophs is the answer
Example : plants
Plants and some bacteria (e.g., cyanobacteria) carry out autotrophic nutrition, synthesizing their own organic molecules using light or inorganic substances.
Organisms that carry out autotrophic nutrition are capable of producing their own organic compounds and energy sources using inorganic substances. One example of an organism that performs autotrophic nutrition is plants. Plants possess specialized structures called chloroplasts that contain chlorophyll, a pigment responsible for capturing sunlight energy.
Through the process of photosynthesis, plants convert carbon dioxide and water into glucose, a form of stored energy. This energy is then used by the plant for growth, development, and other metabolic processes. Additionally, some bacteria and protists are also capable of autotrophic nutrition. These organisms utilize different mechanisms such as chemosynthesis or photosynthesis to synthesize their own organic compounds and derive energy from non-organic sources, such as inorganic chemicals or light, respectively.

Answer:
1. C
2. A
3. A
4. B
Explanation:
hope this helps. ♥️
Parasitism is the type of symbiosis that occurs between a deer and the tick. So, the correct option is C. This is because bacteria infect their host cell which is found in Deer.
What do you mean by Symbiosis?Symbiosis may be defined as a relative ecological association between the individuals of two or more different species.
The type of symbiotic relationship found between oxpecker and zebra is Mutualism. This is because oxpecker is able to get its prey (food), while zebra is benefitted from the removal of insects from their body. So, the correct option is A.
The type of symbiotic relationship between Humans and bacteria living in their digestive tract is Mutualism. This is because Humans are benefitted from bacteria as they assist in digesting food, while bacteria also benefit to find a proper place where unlimited food is available. So, the correct option is A.
The type of symbiotic relationship between Barnacles and whales is Commensalism. This is because Barnacles are benefitted from excess food and easy transportation, while whales are neither benefitted nor harmed by this relationship. So, the correct option is B.
Therefore, each of the questions are properly described above.

at the most basic level, schizophrenia is best conceptualized as a/an ____________ disorder.
At the most basic level, schizophrenia is best conceptualized as a neurodevelopmental disorder.
It is characterized by a complex interplay of genetic, environmental, and neurobiological factors that disrupt brain development and function during early stages of life.
While the exact causes are not fully understood, research suggests that abnormalities in brain structure, neurotransmitter imbalances, and genetic predisposition contribute to the onset of schizophrenia.
These disruptions may affect cognitive processes, emotional regulation, and perception, leading to symptoms like delusions, hallucinations, disorganized thinking, and social withdrawal.
Understanding schizophrenia as a neurodevelopmental disorder highlights the importance of early detection, intervention, and holistic treatment approaches to improve outcomes and quality of life for individuals affected by this condition.
