Which organisms are secondary consumers in this food web? Select all that apply
Rockskipper, Pufferfish and Peacock Flounder are secondary consumers in this food web. So, the correct options are A, B and C.
What is Food web?A food web is a diagram that shows what is eaten with what in an ecological context and how food chains naturally connect to one another. Consumer-resource system is another term for the food web.
A food web is a comprehensive account of the species that make up an ecosystem and their interactions with one another. It demonstrates how energy is moved along food chains that are connected to other food chains.
After primary consumers, who are primarily herbivores, are omnivores, carnivores, and secondary and tertiary consumers. The apex predators are those animals that have no other predators save humans. They are at the highest point in the food chain.
Therefore, the correct options are A, B and C.

I need a small text (about 50 words) for the human brain.
Answer:
The human brain is the command center for the human nervous system. It receives signals from the body's sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains.The largest part of the human brain is the cerebrum, which is divided into two hemispheres, according to the Mayfield Clinic. Underneath lies the brainstem, and behind that sits the cerebellum. The outermost layer of the cerebrum is the cerebral cortex, which consists of four lobes: the frontal, parietal, temporal and occipital. [Nervous System: Facts, Functions & Diseases]
Like all vertebrate brains, the human brain develops from three sections known as the forebrain, midbrain and hindbrain. Each of these contains fluid-filled cavities called ventricles. The forebrain develops into the cerebrum and underlying structures; the midbrain becomes part of the brainstem; and the hindbrain gives rise to regions of the brainstem and the cerebellum.
Explanation:
Which of these structures are found in plant cells but not animal cells?
1. Cell membrane
2. Cell wall

Which is an example of a scientific theory?
A. On average, larger mammals sleep longer than smaller mammals.
B. If a plant receives pure water, then it will grow more than one that
receives salt water.
C. Organisms evolve over time due to changes in heritable physical
characteristics.
D. If a person takes at least one vitamin per day, then it will reduce a
person's level of tiredness.
HELP PLEASE!
Answer: Organisms evolve over time due to changes in heritable physical characteristics.
Explanation:
There are a few things to look for when distinguishing between a nonscientific theory and a valid scientific theory. One thing to consider is if there are any published literature, experimental studies, and data available to support the theory. Most scientific theories have data and information tied to them. Another factor to examine is who has developed the theory. A scientific theory will always be supported by evidence with large quantities of data and testing. An example of a scientific theory is the theory of evolution, which observes changes in heritable physical traits over time in an organism. A hypothesis might be that all organisms evolve at the same rate.
Organisms evolve over time due to changes in heritable physical characteristics is an example of a scientific theory known as evolution. Thus, option C is correct.
What is evolution?Evolution is the scientific theory that explains that "a change in the characteristics of biological populations over next generations.
According to scientists RNA is the first existing molecule on earth that replicate by itself and the process of evolution lead to advanced forms of life.
These characteristics are easily trasfered from one generation to other generation.
Therefore, Organisms evolve over time due to changes in heritable physical characteristics is an example of a scientific theory known as evolution. Thus, option C is correct.

what is chemical weathering? what are some facts?
Answer:
Chemical weathering is the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
Explanation:
1. There are four types of chemical weathering: Reaction with water, Reaction with acid, Reaction with oxygen, and Reaction with organisms.
2. Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals.
