Which characteristic would be most useful in determining if a cell is a plant cell?
Answer:
cell wall
Explanation:
Raul wants to study how pot size affects the growth of plants. To do this, he intends to purchase three different pots of varying diameter. Then, he will fill each pot with the same amount of soil and plant different kinds of flowers in each pot. Finally, he will place the pots side by side in a sunny location and water each pot daily with the same amount of water.
Answer:
No
Explanation:
Based on the exact methodology that Raul is using he will never produce valid results. This is mainly due to the fact that there are too many changing variables in his experiment. In order to produce valid results, the experiment can only have one changing variable (independent variable) at a time, while all of the other variables need to be controlled/constant. This would allow Raul to isolate which change is actually causing the desired effect in the plants. The way that Raul has his experiment set-up he will not be able to pinpoint exactly what variable or aspect is actually causing the growth of the plants.

Which of the following is NOT a form of active transport? A) cyclosis B) phagocytosis C) diffusion D) pinocytosis
Diffusion is not active and instead a form of passive transport. So the correct option is option C.
Because diffusion is a non-electrical process, small particles move faster than larger ones. For example, molecules such as oxygen, CO2, and glucose move through cells.
Active transport involves moving molecules from a low-concentration region to a high-concentration region. In contrast to diffusion, active transport involves moving molecules against a concentration gradient.
The term “active” refers to the fact that transport is energy-dependent. Active transport is energy-intensive, whereas diffusion is energy-free.

what is one reason cell biology is important? explain
Cell biology helps in understanding the state of cell, its functioning, which further helps in understanding the living things more clearly.
Cell biology• A branch of biology, which examines and studies the function, structure, and behavior of cells.
• All living things are formed of cells, and a cell is the fundamental unit of life, which is accountable for living and working of organisms.
• Cell biology is important as by knowing how the cell functions in both diseased and healthy conditions, the cell biologists can work with plant, animal and medical science and will be able to create novel vaccines, plants with better qualities, and more efficient medicines.
Thus, cell biology is a branch that deals with the study of cells, which can further help in better understanding of the living things around us.

Where and how do hurricanes form?
Explanation:
Hurricanes form over the warm ocean water of the tropics. When warm moist air over the water rises, it is replaced by cooler air. The cooler air will then warm and start to rise. This cycle causes huge storm clouds to form.
Hurricanes can be defined as a serious type of storm which forms over
tropical or subtropical waters.
Hurricanes typically forms in the warm ocean water of the tropical or
subtropical regions
Hurricane involves the warm moist air over the water rising due to
evaporation which is then replaced by cooler air. The cooler air then warms
up and start to rise and then the cycle continues. This continuous cycle
makes huge storm clouds to form.

5. What do porifera use their flagella for?
(1 Point)
O swimming
O eating
reproducing
Answer:
Porifera use their flagella to eating.
Explanation:
Porifera are immobile animals, typical of marine ecosystems, also called sea sponges and characterized by a lack of true tissue.
Coanocytes are one of the main cells of the porifers, and they are endowed with flagella that allow them to mobilize the water with food particles towards the microvilli, structures that trap them to be later absorbed.
The flagella play an important role in the feeding of the porifers, by conducting the food to the structures responsible for its absorption and processing.
The other options are not correct:
Porifera is immobile, so the flagella do not participate in swimming.Flagella do not participate in the reproductive process of marine sponges.True or False: Metals have a higher melting point than water.

3. Evaluate Information Sodium is an example of an alkali metal. The alkoli metals are
found in the leftmost column of the periodic table, known as Group 1. Use the interactive
periodic table to explore the properties of the following alkali metals: lithium (Li), sodium
(No), potassium (K), rubidium (Rb), and cesium (Cs). The animations demonstrate a chemical
property common to alkali metals: they react with water. How does the reactivity vary
among this group of elements? Why might patterns like this be useful to scientists?
Answer: This might be helpful because t is a good basis for organizing elements because each element has a unique number of protons and atomic mass is an indirect way of organizing elements by number of protons.
