Answer:
Eukaryotes have membrane bound organelles, and Prokaryotes dont have a necleus.
Explanation:
Eukaryotes have membrane bound organelles, and Prokaryotes dont have a necleus.
Answer:
Prokaryotic and Eukaryotic cells differ in that Eukaryotic cells have membrane-bound organelles, and Prokaryotic cells do not have a nucleus.
Explanation:
So, Prokaryotic cells, are mainly found in multicelled organisms. They are cells whose nucleus is not held by a membrane.
Eurkroyates on the other hand, are cells that have a membrane-bound nucleus and/or organelles as their major characteristic.

Riparian zones can reduce the impact of water pollution. Please select the best answer from the choices provided True or False
Answer:
It true did the test just now
Explanation:
True. Riparian zones can reduce the impact of water pollution.
What are Riparian Zones?Riparian zones are the areas of land located along the banks of rivers and streams. They are important ecosystems that provide a variety of ecological, hydrological, and biological services, such as water filtration, flood control, habitat for wildlife, and recreation opportunities.
Riparian zones are also crucial for maintaining the overall health of river systems and for mitigating the impacts of human activities such as agriculture, urbanization, and resource extraction.

Identify the macromolecule in the figure that store genetic information in molecules DNA, and RNA?
Answer:
The correct answer is - option 2. (chemical structure of the nucleotide)
Explanation:
Nucleic acid, DNA and RNA stores genetic information which helps in produces various proteins and for the next generation of the cells. Nucleic acids are made up of monomers of nucleotides joined together to form the nucleic acids. Each nucleotide has sugar, a nitrogenous base, and phosphate in the structure that joined to form a helix structure.
Thus, the correct answer is - option 2.

How do diatoms and algae obtain their food?
Answer:
Explanation:
I don't know how diatoms obtain their food, but I do know how algae obtains it. Algae is a plant, that green stuff you find growing on rocks in creeks and lake shores. Plants turn sunlight, water, and carbon dioxide into sugars, which it uses for food. Most plants also obtain nutrients from soil and water using their roots, but algae doesn't have roots so it only gets food through the process I explained above, photosynthesis. I hope this has been helpful.
Answer:
Diatoms
Explanation:
They obtain food by absorbing nutrients from ocean water. Unlike many other types of phytoplankton and marine organisms, diatoms don’t have body parts that allow them to swim. They obtain food by absorbing nutrients from ocean water, which is a very competitive process. Diatoms are relatively large and at a disadvantage for food absorption due to their bodies’ reduced surface areas.
Which of the following is the most likely function of this shape?
The energy in glucose cannot be released by
respiration
glycolysis
burning
photosynthesis
Answer: Photosynthesis
The energy in glucose cannot be released by photosynthesis.
How Can the energy in glucose be released by photosynthesis?
During photosynthesis, “producers” like green plants, algae and some bacteria convert light energy from the sun into chemical energy. Photosynthesis produces chemical energy in the form of glucose, carbohydrate or sugar.
Thus, photosynthesis is the correct option.

Root cells of plants take in some minerals from the surrounding soil by spending energy. After the plant obtains enough minerals to maintain health, the plant will continue to absorb minerals from the soil. Which reason best explains why root cells need to spend energy in order to transport some minerals into cells?
The question is incomplete; the complete question is;
Root cells of plants take in some minerals from the surrounding soil by spending energy. After the plant obtains enough minerals to maintain health, the plant will continue to absorb minerals from the soil. Which reason best explains why root cells need to spend energy in order to transport some minerals into cells?
Root cells are unable to use sunlight energy for mineral uptake.
Mineral concentration is higher in root cells than in the surrounding soil
Cell membrane pores in roots are too small for passive uptake of minerals
Cell membranes in roots lack proteins for the passage of minerals.
Answer:
Mineral concentration is higher in root cells than in the surrounding soil
Explanation:
Mineral uptake by plant roots occurs by active transport of ions into the cells of root hairs, this process requires energy.
The concentration of minerals in the soil is quite low. The root hair cells of plants possess carrier proteins that carry mineral ions and move them into the cell against existing concentration gradient. This process requires energy and is known as active transport.

How are the particles in this picture below organized?
from high particle motion to low particle motion
from low particle motion to high particle motion
the particle motion is the same in all stages
Answer:
Solid, liquid, Gas
Explanation:
Yeet
Answer:
At this level, students are expected to 'explain the behaviour and properties of materials in terms of their constituent particles and the forces holding them together’ (VELS standards Level 6). However, the fact that students may be able to draw the usual static arrangements of particles in solids, liquids and gases does not mean that they hold a fully particulate view of matter. Research evidence suggests that many students at this age and older still hold a number of alternative conceptions about particles which prove difficult to extinguish. They often lack an appreciation of the very small size of particles, attribute macroscopic properties to microscopic particles, have difficulty appreciating the motion of particles in all states of matter and have problems understanding forces between particles.
