In a mangrove swamp, mangrove tree crabs consume the leaves of mangroves and are food for other animals. By eating decaying mangrove leaves, animal wastes, and dead animals, they help create detritus that forms the base of many of the swamp's aquatic food chains. In addition, they burrow in the wet soil, which mixes air containing oxygen with the soil. What is likely to happen to the stability of the community if a disease destroys the population of mangrove tree crabs? (1 point) Think about how a community adjusts when one species is negatively affected.
The stability of the community if a disease destroys the population of mangrove tree crabs will be reduced.
What is a Community?This is referred to as a place where organisms who share certain characteristics live and interact.
The importance of the mangrove tree crabs such as food sources will reduce the stability as other organisms will be affected if its population declines. The community adjusts when one species is negatively affected through exploring different substitutes available.

B. mRNA delivers DNA code to the ribosome and tRNA delivers amino acids to the ribosome
C. tRNA delivers DNA code to the nucleus and mRNA delivers proteins to the ribosome
D. mRNA delivers DNA code to the nucleus and tRNA delivers proteins to the ribosome
Answer:
The right answer is D.
Explanation:
The messenger ribonucleic acid, messenger RNA, or mRNA is a transient copy of a portion of the DNA corresponding to one or more genes. mRNA is used as an intermediate by cells for protein synthesis. Jacques Monod, François Jacob, and their collaborators issued and showed the concept of messenger RNA in 1960.

Which DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells?
The DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells is nucleus.
What is nucleus?The part of a cell that houses the chromosomes in biology. The membrane-enclosed nucleus is where RNA is synthesised from the chromosomal DNA.
DNA is organised into chromosomes in the nucleus, which is located in the centre of the cell.
The double nuclear membrane (outer and inner) that separates the nucleus from the cytoplasm, known as the nuclear envelope, envelops it. The rough endoplasmic reticulum and the outer membrane are one unit.
The nucleolus' main job is to facilitate ribosome biogenesis by assembling and digesting rRNA into preribosomal particles.
Bacterial cells lack the nucleus, the primary cell structure that houses DNA, that is present in plant and animal cells.
Thus, nucleus is only present is eukaryotic cells.

All of the major components of the light reactions, including the pigment molecules
clustered in photosystems I and II, are located in the thylakoid membrane. What is the advantage of
having these components confined to the same membrane rather than dissolved in the stroma or the
cytosol/cytoplasm? Explain your argument. (up to 5 points)
Answer:
Having the light reaction components in close proximity speeds up the process. Electrons move from one protein to the next in sequence. If the proteins had to 'swim' around to find the next part of the electron transport chain, then the ATP would form at a much slower, inefficient rate.

Which is the BEST example of an organism using behavior to maintain homeostasis?
AO A chameleon's skin becomes green when it sits on a leaf.
B
An alewife turns when other members of its school turn.
C
A snake moves from a sunny area to a shady area to cool down.
D. An elephant uses low-frequency sound waves to find its herd.
C
A snake moves from a sunny area to a shady area to cool down.
Homeostasis is a process to regulate and maintain the temperature and internal body environment. A snake moving from a sunny to a shady region to cool down is behavioral homeostasis. Thus, option C is correct.
What is homeostasis?Homeostasis has been defined as the process that maintains the relative equilibrium temperature of an internal environment so as to regulate physiological processes. They are essential for maintaining optimal functioning.
A snake shows behavioral homeostasis when it moves from a sunny area to a shade region so as to cool its body temperature. The mode of temperature regulation is behavioral homeostasis which regulates the body temperature.
Therefore, option C. the snake moving to a shady area from a sunny area is behavioral homeostasis.

Calculate the distance to the ocean floor if a sonar signal takes 6 s to return to a ship's receiver
Answer:
If it takes the sound 6 seconds to get to the floor and back, then it takes 3 seconds to reach the floor. So all you would need to do multiply (3 seconds) x (the speed of sound in water) = distance to sea floor. The internet can tell you the speed of sound in water, though just make sure you look for it in the units (feet or meters) that you want. I hope that helps.
Answer:
2500.
Explanation:
All you would need to do multiply (3 seconds) x (the speed of sound in water) = distance to sea floor.

Ecologists study both biotic and abiotic factors and how they interact. Therefore, ecologists often use methods and data from other areas of science, such as geology, geography, climatology, chemistry, and physics.
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals

Through geology and geography, we can study biotic and abiotic factors within an ecosystem.
How can you study biotic and abiotic factors within an ecosystem?The interactions between biotic factors, such as organisms like flora and fauna, and abiotic factors.
For example, all animals (biotic factors) breathe in oxygen (abiotic factor). All plants (biotic factor) absorb carbon dioxide (abiotic factor) and need water (abiotic factor) to survive.
Thus, geology and geography, are the two ways to study biotic and abiotic factors within an ecosystem.
