i believe the answer is c, cell wall^^

Cell wall supporting part of the plant cell. So, the correct option is C.

What is Cell wall?

A cell wall is defined as the structural layer surrounding certain types of cells present outside the cell membrane which can be rigid, flexible and sometimes rigid. The cell wall provides both structural support and protection to the cell which serves as a filtering mechanism.

Cell wall present only in plants and some fungi, bacteria and algae. The plant cell wall is arranged in 3 layers which are composed of carbohydrates, such as pectin, cellulose, hemicellulose and other small amounts of minerals, which form a network with structural proteins to form the cell wall.

Thus, Cell wall supporting part of the plant cell. So, the correct option is C.

Which statement best predicts why a cell's progression through the cell cycle might be halted by the G1/S checkpoint?

Answers

Answer:

The missing options are:

A. Spindle fibers have not correctly attached to chromosomes.

B. Damage occurred to DNA when it was being copied in G1.

C. There are not enough nucleotides available to construct new DNA.

D. Proteins necessary for M phase of the cell cycle have not been produced.

The correct option is C.There are not enough nucleotides available to construct new DNA.

Explanation:

During the G1 phase, the cell grows in size since it prepares its organelles and molecule combinations for the next phase of the cell cycle, the S phase. Before the cell transitions to the S phase, it has to pass through a checkpoint that makes sure that there are no mutations, it has grown enough, and has the necessary molecules for the next phase, which is the synthesis of DNA. If there are not enough nucleotides, the cell will not be able to synthesize new DNA in the S phase, so the checkpoint stops the cells from moving to this phase till it has all the necessary things to do it.

Based on the living things in the pyramid, please tell me what examples would fit into these categories
Primacy Producers, primary consumers, secondary consumers, and tertiary consumers.

Answers

Answer:

Primacy Producers----- Oak tree , primary consumers------ Caterpillars , secondary consumers ------- blue jays, and tertiary consumers ----- hawk.

Explanation:

Oak tree refers to the primacy Producers in this pyramid because it produces food by using the solar energy. Caterpillars are primary consumers that feeds on the producers and also known as herbivores, blue jays are the secondary consumers that feeds on the primary consumer which is the caterpillar, and tertiary consumers are the hawk that feeds on the secondary consumer i.e. blue jays. In this way, energy flows in the food chain of an ecosystem. During this flow of energy, only 10% of energy is transferred from one trophic level to another while the remaining releases in the environment in the form of heat energy.
