Answer:
oxygen because that's one of the substance that plants produce.
You can also do this by the process of elimination. Knowing that atrazine impedes the production of substances in plants, we know that it can't be DNA and Phospholipid. Carbon Dioxide is used by plant, not produced; thus, oxygen is the answer.
<u>Answer:</u> A. Tissues
<em>Cells that perform similar functions combine to form tissues.
</em>
<u>Explanation:</u>
Cells are the smallest units in the body of an organism. Based on number of cells in an organism’s body they can be classified as unicellular or <em>multicellular organisms</em>.
It is the group of cells performing similar functions that form a tissue. Group of tissues performing similar function forms an organ. <em>Tissue structure and function may differ in plants and animals. </em>
Animal tissues are classified into four. They are epithelial tissue, connective tissue, nervous tissue and muscle tissue. In plants there are three tissue systems namely the <em>epidermis, vascular tissue and the ground tissue.
</em>
Gneiss typically has a banded, foliated or platy texture.
Answer:
in phagocytosis, the cell membrane surrounds the particle and engulfs it. ( credit: Mariana Ruiz Villareal) Phagocytosis (the condition of “cell eating”) is the process by which large particles, such as cells or relatively large particles, are taken in by a cell.
Explanation:
Answer:
3. into ice, which is denser than liquid water.
Explanation:
Water molecules are held together by hydrogen bonds. The bonding is usually between the hydrogen atoms of one water molecules, and oxygen atom of neighboring water molecules. Structurally, both oxygen and hydrogen atoms pulls the electon towards themselves.Thus both atoms share electron by covalent bonding.
However, because oxygen has a strong positively charged nucleus it pulls the electron more to itself than oxygen. Thus oxygen is partially negative and oxygen is partially positive. This interactions take place among all the oxygen and hydrogen atoms in water molecules. . The unequal charge distributions is called dipole and the attraction between oxygen and hydrogen is called hydrogen bonding .
The orientation of hydrogen and oxygen molecules from dipole -dipole interactions of hydrogen bonding makes the oxygen and hydrogen atoms in ice to be pushed apart well spaced out in ice, making them less dense than liquid water where they were aggregated. Thus from the question option C is correct.
