Which describes a difference between bivalves and cephalopods?
Bivalves use tube feet for movement, and cephalopods use muscular feet for movement.
Bivalves live only in ocean environments, and cephalopods live in a variety of aquatic environments.
O Bivalves use a radula to feed, and cephalopods use filter-like structures to feed.
O Bivalves have an open circulatory system, and cephalopods have a closed circulatory system.
Answer: D - Bivalves have an open circulatory system, cephalopods have a closed circulatory system
Explanation: I had to research the differences to find the answer
A difference between bivalves and cephalopods are bivalve animals use a radula to feed, and cephalopods use filter-like structures to feed, that is the third option, where they both belong to the Mollusca phylum.
What is the significance of bivalves and cephalopods?Both bivalves and cephalopods belong to the mollusca phylum, and they are invertebrates, some of the bivalves, such as oysters and mussels, are important as they are a source of food for humans and as filter-feeding organisms; at the same time, squid and octopus are cephalopods. These organisms are significant in different fields of study, such as neuroscience and evolution.
Hence, a difference between bivalves and cephalopods are bivalve animals use a radula to feed, and cephalopods use filter-like structures to feed, that is the third option, where they both belong to the Mollusca phylum.

Answer:
the answer is D. all of the above
Explanation:
i got 100% on my quiz :)
Satellite imaging allows scientists to observe where deforestation has removed the trees, where deforestation has occurred but is recovering, and where deforestation has not occurred. Thus, the correct option for this question is D, i.e. all of the above.
What is Deforestation?Deforestation may be defined as the process of cutting down trees or the clearance of forests for the purpose of urbanization and industrialization. It can involve the conversion of forest land to farms, ranches, or urban use.
According to the context of this question, satellite imaging may be defined as a type of technology that gathers or collects information across the world with the help of satellites. The activity of deforestation is analyzed by this process along with recovering the surface.
Therefore, the correct option for this question is D, i.e. all of the above.

15. Explain how it would be possible to have a change in a single base of DNA, but have the protein NOT change and be functional.
Answer:
Nonsense mutation. A nonsense mutation is also a change in one DNA base pair. Instead of substituting one amino acid for another, however, the altered DNA sequence prematurely signals the cell to stop building a protein. This type of mutation results in a shortened protein that may function improperly or not at all.Sep 21, 2020

what are the inputs for photosynthesis and where are they used?
Answer:
In terms of inputs, outputs and energy transformations, photosynthesis can be summarized as follows. Inputs - Sunlight as energy source, carbon dioxide and water. Processes - Chlorophyll traps sunlight; the energy is used to split water molecules; hydrogen from water is combined with carbon dioxide to produce glucose.

The opening and closing of _____________in your heart create the lub-dub sound and prevent the backflow of blood.
What goes in the blank?
Answer:
Heart valves or the closure of the mitral and tricuspid atrioventricular (AV) valves at the beginning of ventricular systole and the closure of the aortic valve and pulmonary valve at the end of ventricular systole.
Explanation:
The heart tone “lub,” or S1, is caused by the closure of the mitral and tricuspid atrioventricular (AV) valves at the beginning of ventricular systole.
The heart tone “dub,” or S2 ( a combination of A2 and P2), is caused by the closure of the aortic valve and pulmonary valve at the end of ventricular systole.

Answer:
Which of the following statements about exponential growth curves is true?
- a. Exponential growth curves are common for R-selected species.
Explanation:
The statement that is true about exponential growth curves is as follows:
Exponential growth curves are common for R-selected species.Thus, the correct option for this question is A.
What is an Exponential growth curve?An Exponential growth curve may be defined as a type of growth curve that significantly illustrates greater increases in the population of organisms with respect to time. It immediately represents the growth with extreme fast rates.
Exponential growth is followed by the continuous breeding population which contains more individuals than a similar population breeding annually. It includes examples like some insects, r-selected species, etc.
The shape of the exponential growth curve is J-shaped. It represents only fast growth rates. While the logistic growth curve shows fast growth rates followed by slow growth rates. It possesses a shape known as S-shape. It represents the growth rate of k-selected species.
Therefore, the correct option for this question is A.
