Answer: Proteins
◍ Unsaturated.
Answer: Double bond in their hydrocarbon tail. LIQUID at room
temperature.
◍ What is DNA made of?.
Answer: nucleotides
◍ Exocrine action.
Answer: Those hormones which secrete their essential product by way of a
duct to some environment external to itself, either inside the body or on a
surface of the body
◍ Cell division occurs most rapidly in?.
Answer: Cancerous tissue
◍ What are the female parts of a plant?.
Answer: Pistil (female reproductive organ)Stigma (top part of pistil)Style
(slender stalk below the stigma)
◍ The plasma membrane is made of/ composed of what?.
Answer: lipids, proteins, and carbohydrates
◍ During aerobic respiration, which one of the following substances is
released?.
Answer: 36ATP
◍ In contrast to triglycerides phospholipids are lacking what component ?.
, Answer: Fatty acid
◍ Cytosol.
Answer: The cytosol is the fluid in which organelles of the cell reside. This
is often confused with cytoplasm, which is the space between the nucleus
and the plasma membrane.
◍ What is a single cell that results from the fertilization of an egg cell by a
sperm cell?.
Answer: zygote
◍ Polygenic Inheritance.
Answer: Combined effect of two or more genes on a single character
◍ Telophase.
Answer: Gather on either side of the now separating cell. END of mitosis.
◍ Metabolic pathway.
Answer: In a cell, it's a reaction that takes place in a series of steps
progressing from a standpoint of high energy to low energy. All reactions
are catalyzed by the use of enzymes.
◍ The plasma membrane is soluble to?.
Answer: Lipids
◍ The utilization of the products of digestion for production of energy or
synthesis of cellular material is called:.
Answer: Assimilation
◍ The process of making mRNA using DNA as a template is called.
Answer: Transcription
◍ How does asexual reproduction differ from sexual reproduction?.
Answer: sexual reproduction involves two cells that contribute genetic
material to daughter cells, resulting in significantly greater variation
◍ Saturated.
Answer: Clogs arteries. NO DOUBLE BONDS in their hydrocarbon tail.
SOLID @ room temperature.
,◍ What is the site of cellular respiration? (eukaryotic cells).
Answer: mitochondria
◍ Which gives the order of four taxonomic categories from least to most
specific?.
Answer: Kingdom phylum class order family genus species
◍ What is represented by this formula 6CO2+6H2O=>C6H12O6+6O2.
Answer: Photosynthesis, carbon dioxide pairing with water to form a simple
sugar and oxygen
◍ Phototrophs.
Answer: "plants" feed themselves with light.
◍ What drives the cell/ pushes it forward?.
Answer: propulsion
◍ The smallest known microorganisms are?.
Answer: Viruses
◍ Codominance occurs when?.
Answer: Both the alleles in a heterozygote are expressed phenotypically in
an individual
◍ Mitochondria.
Answer: Found in Eukaryotic cells and are the site of CELLULAR
RESPIRATION
◍ Which pair of organelles is responsible for energy supply to eukaryotic
cells?.
Answer: Chloroplast and mitochondria
◍ Interphase is the phase of a cell cycle in which?.
Answer: The cell performs its unique functions
◍ The two catabolic pathways that lead to cellular energy production are:.
Answer: cellular respiration and fermentation
◍ T-rna.
, Answer: TRANSFERS appropriate amino acids to the ribosome for building
the protein.
◍ Which of the following is true with regard to eukaryotic and prokaryotic
cells?.
Answer: Eukaryotic cells have mitochondria.One of the major differences
between eukaryotic cells and prokaryotic cells is that eukaryotic cells
contain organelles, such as mitochondria, whereas prokaryotic cells do not.
◍ How is mitosis different from meiosis?.
Answer: Meiosis creates sex cells with half the # of chromosomes of the
parent cell where as mitosis creates cells that are exact copies of each other,
down to the number of chromosomes
◍ Which color of light is least effective at driving photosynthesis?.
Answer: Green
◍ A cellular organelle found in typical plant cells but not in typical animal
cells is the?.
Answer: Chloroplast
◍ With which organelle is the synthesis of ATP associated?.
Answer: Mitochondrion
◍ Virtually all chemical reactions of the cell are catalyzed by?.
Answer: Enzymes
◍ The mRNA strand is what DNA strand?.
Answer: identical except T is replaced with U
◍ What is the main component of blood plasma?.
Answer: water
◍ Which part of cellular respiration produces the greatest amount of ATP?.
Answer: electron transport chain
◍ Properties of Water.
Answer: 2 Hydrogen bonds Covalently bonded to Oxygen.Hydrogen
Bonding between molecules.- High specific heat- Large bodies or water
