Answer:
Characteristic of the Carboniferous period (from about 360 million to 300 million years ago) were its dense and swampy forests, which gave rise to large deposits of peat. Over the eons the peat transformed into rich coal stores in Western Europe and North America. The name "Carboniferous" refers to this coal.

Question 2 of 7
What is a product in photosynthess
Carbon diokide
glucose
Answer:
glucose
Explanation:
The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas.
Which organelles work together to get glucose into the cell for energy to be made?
A The cell wall lets the glucose into the cell. The glucose moves across the cytoplasm to the chloroplast so that energy can be
created
B The cell wall lets the glucose into the cell. The glucose moves across the cytoplasm to the mitochondria so that energy can be
created
DC The cell membrane lets the glucose into the cell. The glucose moves across the cytoplasm to the chloroplast so that energy can be
created
OD The cell membrane lets the glucose into the cell. The glucose moves across the cytoplasm to the mitochondria so that energy can
be created
Answer: The cell wall lets the glucose into the cell, the glucose then travels through the cytoplasm to the mitochondria to create energy
Explanation:
What is the function of the cell membrane in a cell?
Answer: The plasma membrane or cell membrane provides protection for a cell
Explanation: it also provides. Functions
The function of the cell membrane in a cell is that the plasma membrane or cell membrane provides protection for a cell or we can say that the function of cell membrane is to protect the cell.
What is cell membrane?The cell membrane has been defined as the structure found in the cell and the function of cell membrane is to provide protection to the cell. The cell contain several cell organelles and these are ribosomes, golgi appratus, nucleus, and the cell organelles have different functions.
When movement of molecules is takes place then it is called active transport. Active transport movement is always from lower concentration to a region of higher concentration gradients. So we can say that substance are moving their own concentration gradients.
Therefore, The function of the cell membrane in a cell is that the plasma membrane or cell membrane provides protection for a cell or we can say that the function of cell membrane is to protect the cell.

What process do cells use to release energy without oxygen? *
cellular respiration
O digestion
O fermentation
O photosynthesis
Photosynthesis is a process which uses light energy, convert it into chemical energy and uses it to release energy without oxygen. Therefore, option (D) is correct.
What is photosynthesis?Photosynthesis is a process that plants and other organisms utilize to transform the energy from light into chemical energy. This chemical energy can then be used to fuel the activities of the organism later on through a process called cellular respiration.
Plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis. Water is oxidized, meaning it loses electrons, while carbon dioxide is reduced, gaining electrons, within the plant cell. This converts water to oxygen and carbon dioxide to glucose.

What is the purpose of Mitosis? *
A. To produce an egg and a sperm cell.
B. To produce a new organism (like bacteria).
C. To produce a new cell (NOT a new organism).
D. To differentiate.
Answer:
C.
Explanation: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
Hope this helps! Have a nice day!
Answer:
C. to produce a new cell
Explanation:
Mitosis consists in replicating the genetic material of a mother cell in order to make two identical daughter cells; this is a diploid process. In order to make an egg or sperm cell and eventually a new organism, the correct process would be meiosis, since it combines the DNA between two cells and it is an haploid process.

What direction will the particles move across the cell membrane?
Answer:
Simple Diffusion across the Cell(Plasma) Membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobicmolecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.

It is already clear that behavior is rarely controlled by – . Rather, almost all behavior involves – , and often specific – factors influence how genes are expressed.
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of options but the complete question is in the attached picture below.
The human genome is the basic genetic code, or blueprint, for the transfer of traits from parents to offspring through -hereditary transmission- . Studying this code -has revealed- ways to partially correct genetic defects after birth. It is already clear that behavior is rarely controlled by -a single gene- . Rather, almost all behavior involves -multiple genes- , and often specific -environmental- factors influence how genes are expressed.
It would be noted that some of the options were not chosen at all, this is because this question focuses on genes and it's expression. "Nurture and education" and "psychological" are not factors that actually affect gene expression. Also, studying genetic codes has already revealed partial ways to correct genetic defects and hence it would be wrong to choose "may in time reveal". For instance, there are procedures used to identify genetic defects in the spermatozoa of a male which can be screened out and the "good" sperm used to fertilize an egg in-vitro.
