Answer:
Structure of a leaf
The cuticle helps retain water inside the leaf cells. The epidermis houses the guard cells which regulate the movement of water into and outside the cell. Guard cells do so by controlling the size of the pores also called stomata. Mesophyll: This forms the middle layer of the leaf.

how to determine if a molecule has a dipole moment
Answer:
Explanation:
The larger the difference in electronegativity between the two atoms, the more electronegative that bond is. To be considered a polar bond, the difference in electronegativity must be large. The dipole moment points in the direction of the vector quantity of each of the bond electronegativities added together.

How is the goal of evolutionary classification different from linnaean classification.
Answer:
The goal of evolutionary classification
Explanation:
The goal of evolutionary classification is to group species into larger categories that reflect lines of evolutionary descent, rather than overall similarities. The goal of linnaean classification is to group species into larger categories based on physical characteristics
During mitosis, a single cell divides to produce two daughter cells. What
must happen in the original cell so that each of the daughter cells has a
compiate set of chromosomes?
Answer:
DNA replication
Explanation:
DNA replication creates duplicates of the existing chromosomes, so that when the cell splits to create two new cells, they will each have their own set of DNA.

A- ultraviolet radiation causing skin cancer
B- a longtime smoker developing cancer in the lungs
C- exposure to a chemical that affect cell formation
D- exposure to a chemical that affects the nervous system
Answer:
C- exposure to a chemical that affect cell formation
Explanation:
Hope this helps
The situation that is most likely to result in a mutation that is passed on to an offspring is exposure to a chemical that affects cell formation. The correct option is C.
What is mutation?A mutation is changing or modification in the nucleic acid or DNA sequence of a person. This is a natural process that occurs due to mutagens.
Mutation can also be artificially induced to bring out changes in the gene sequences for specific reasons. An example is an aneuploidy is a condition of the presence of more or less number of chromosomes than normal. For example, there are 45 or 47 chromosomes are present.
There are different types of mutations somatic mutation occurs in the body cell and chromosomal mutation occurs in the structure of chromosome coin mutation changing the nucleotide.
Therefore, the correct option is C. exposure to a chemical that modifies cell formation.

What type of cell transport is shown in the figure below?
Facilitated diffusion
Active transport
Endocytosis
Simple diffusion
The type of cell transport which is shown in the figure in question is Facilitated diffusion. The diffusion in this transport is carried out with the help of a protein such as carrier protein or channel protein. Thus, the correct option is A.
What is Facilitated diffusion?
Facilitated diffusion is a type of diffusion where the movement of solute and solvent particles takes place from the region of higher concentration to the region of lower concentration.
The cell membrane is selectively permeable in nature as it allows the movement of selected substances through it. The molecules which are impermeable such as large, charged polar molecules cannot cross the membrane on their own and hence requires a protein which facilitates their movement. Thus, for this purpose the carrier and channel proteins which are present in the membrane facilitate this diffusion of substances.
Therefore, the correct option is A.

What is the difference between a benign tumor and a malignant tumor? View Available Hint(s)for Part A Benign tumors will not kill you; malignant tumors will. A benign tumor is a mass of essentially abnormal cells; a malignant tumor is an abnormal mass of essentially normal cells. Benign tumors do not metastasize; malignant tumors do. Benign tumors metastasize; malignant tumors do not.
Answer:
These cells can form a mass called a tumor. A tumor can be cancerous or benign. A cancerous tumor is malignant, which means that it can grow and spread to other parts of the body. A benign tumor means that the tumor can grow, but it will not spread.
what part of the plant holds the most water
Answer:
Stem
Explanation:
Main Stem - Holds up the plant and carries water throughout the plant. Secondary Stem - A stem that grows out from the main stem and holds the leaves. Chlorophyll - The green matter that is needed to make food for the plant.
Answer:
vacuoles
Explanation:
Plant cells are unique in that they have a large central vacuole. A vacuole is a small sphere of plasma membrane within the cell that can contain fluid, ions, and other molecules. Vacuoles are essentially just large vesicles. They can be found in the cells of many different organisms. However, plant cells characteristically have a large vacuole that can take up anywhere from 30% to as much as 90% of the total cell volume.

The steps of mitosis are in the order of prophase, metaphase, anaphase, telophase.
What are mitosis and its four stages?Mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei.
Mitosis comprises four basic phases: prophase, metaphase, anaphase, and telophase. These phases occur in this strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. The mitotic phase is a relatively short period of the cell cycle. It alternates with the much longer interphase, where the cell prepares itself for the process of cell division. Interphase is divided into three phases: G1 (first gap), S (synthesis), and G2 (second gap).
Thus, the order of phases in mitosis is in the order of prophase, metaphase, anaphase, telophase.
