Tides on Earth are influenced by
both the moon and the sun
the sun only
the moon only
neither the moon nor the sun
Answer:
The moon only
Explanation:
The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.

Characteristics demonstrate that sea anemones are animals and not plants are;
The cells do not contain a membrane-bound nucleus; that is, they are prokaryotic.The organism consists of cells that perform chemosynthesis.What are sea anemones?. They are soft-bodied, sedentary colourful flower-like animals. They are attached to the sea bed with the help of a fleshy foot.
.Thus, the move of sea anemones is restricted. They are good predators and catch prey with their tentacles. Sea anemones possess features of animals thus, cell wall is absent in their cells

Which statement describes a difference between the nitrogen and carbon cycles?
The nitrogen cycle occurs entirely in the ocean.
The nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria.
The carbon cycle requires freezing temperatures.
The carbon cycle involves only plants.
Answer:
The nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria
The primary distinction between the carbon and nitrogen cycles is that the former involves recycling carbon, whilst the latter involves recycling nitrogen. There are numerous ways for both systems to recycle carbon and nitrogen. With gases, both cycles begin and end. Thus, option B is correct.
What between the nitrogen and carbon cycles?Both go through chemical changes that change the shape of the molecules they are contained in. All organisms that are living contain both nitrogen and carbon. Both entail releasing the element into the atmosphere in a molecular form. The cycles start and end as gases.
Therefore, The amount of nitrogen that can be absorbed into organic matter and then recycled rises as the flux of carbon does.Both involve releasing the element as a molecule form into the atmosphere. As gases, the cycles begin and finish.

Cell division occurs in animal cells and plant cells. The illustration below shows an animal cell and a plant cell during the same phase of cell division.
Which of the following best describes this phase of cell division?
A. The cells are completing the growth phase and entering prophase.
B. The chromosomes in each cell have just replicated, and the cells are entering mitosis.
C. Mitosis is complete and the plant cell is forming a cell plate because plants have cell walls.
D. The cells are in metaphase, and the animal cell is drawing inward where chromosomes will line up for separation.
Answer:
C
Explanation:
The membrane of the animal cell is beginning to pinch off indicating cytokinesis which is the final stage of mitosis in eukaryotes
The plant cell has entered telophase (the final stage of cell division for prokaryotes) as a cell plate has formed as well as two separate nucleus'
Which of the following is a feature of all cells?
O A. All cells have a nucleus.
O B. All cells have a rigid cell wall.
O C. All cells are spheres.
O D. All cells have a cell membrane.
All cells have a rigid cell wall is a feature of all cells. Therefore, option (B) is correct.
What are the characteristics of cell wall?A plant cell's cell wall is its outermost covering. It is a tough, pliable, and occasionally rigid layer that provides the cell with structural support and protection. There is no cell wall in animal cells.
Plant cells' tensile strength and resistance to mechanical and osmotic stress are provided by the cell wall, which encloses the plasma membrane. Additionally, it permits the development of turgor pressure, or the pressure of the contents of the cell against the cell wall.
The cell's interior contents are kept separate from the outside environment by the cell wall. It also gives the cell and its organelles shape, support, and protection. However, only a few prokaryotic organisms, eukaryotic plants, and fungi contain this cellular component.
