Compare and contrast the functions of carbohydrates and lipids.
Compare and contrast Proteins and Nucleic Acids
Which nutrition label will provide more quick energy, but have the fewest amount of calories?
An advertisement for a health supplement for dogs claims to build lean muscle and strengthen tendons and ligaments, as well as provide energy. Which two biomolecules must the supplement contain to provide these benefits?
Carbohydrates
Lipids
Protein
Nucleic Acid
One of the main functions of the semi-permeable cell membrane is to maintain homeostasis for the cell. Semi-permeable means that only some molecules are allowed to cross the membrane and others are not.
Which biomolecule molecule enables large molecules to cross the membrane?
(a)
Both prokaryotes and eukaryotes have small, free-floating organelles. The cell makes these organelles from nucleic acids and amino acids found in food. Without these organelles, the cell could not make proteins.
These organelles are called (a)
Match the cell structure with its primary function.
Move the correct answers to the correct boxes.
(a) - controls cell activities
(b) - protein synthesis
(c) - controls what goes in and out of the cell
(d) - support
(e) - provides energy for the cell
Which type of movement across a cell’s plasma membrane requires energy supplied by ATP?
Passive Transport
Simple Diffusion
Active Transport
Osmosis
Passive transport is represented in three different forms. (a) is the movement of water across a semipermeable membrane. (b) , like when someone sprays perfume, is the movement of molecules down or under a concentration gradient. (c) is the movement of molecules down a gradient with the help of special protein channels.
Correctly label the image
No, because the excess water would accumulate and burst the cell.
Yes, because the paramecia would simply become bigger organisms.
Yes, because just like all living things, paramecia need water to survive.
No, because the excess water would create a balance between the inside and outside of the cell.
What are the 3 functions of the cell membrane?
Maintain Homeostasis
Protect the inside of the cell from the external environment
Allows specific things to enter or exit the cell (semi-permeable)
Keep all solutes out of the cell, only allows water in
Which statement best describes how a virus replicates?
A virus divides into two identical virus particles before infecting the host cell.
A virus enters a host cell and uses the materials from the host cell to produce new virus particles.
Multiple virus particles fuse and form a large particle that breaks apart, releasing new virus particles.
Multiple virus particles break down in component parts, which then reassemble into new copies of the virus.
Which part of the virus will be used to attach to a host cell receptor?
cell growth
G1
DNA Replicates
S
Interphase
G1, S, G2
M Phase
Cell Division
division of nucleus
Mitosis
Put the following phases into the correct order
Interphase
Prophase
Metaphase
Anaphase
Telophase
Which letter in the image represents metaphase?
Cancer is a disease of uncontrolled cell division. Cancer cells behave differently than normal cells, and function incorrectly during the cell cycle. Which of these best describes how cell division irregularities might lead to cancer?
Cancer cells become "stuck" in G1 of Interphase, which causes each cell to grow excessively large.
Cancer cells keep dividing and do not stop when overcrowded, leading to tumor formation.
Cancer cells remain too long in the DNA Replication part of Interphase, which creates excessive copies of new cells.
Cancer cells divide far less than normal cells, allowing each individual cell to increase in size.
Patients who have lymphoma, a cancer effecting blood cells,
are frequently prescribed a medication called Bleomycin.
This medication stops the growth of cancer cells in the body,
preventing them from dividing or growing.
What phase(s) of the cell cycle would likely be most heavily impacted by Bleomycin?
G1 and Prophase
Mitosis only
S
(DNA Replication)
G2 and Mitosis
What do all living things have in common?
have DNA
maintain homeostasis
able to reproduce
have identical proteins
Match the complementary nitrogen bases together
Adenine
Thymine
Guanine
Cytosine
Thymine
Adenine
Cytosine
Guanine
Label the nucleotide
Label the image
DNA molecules contain the genetic information that determines the characteristics of a living organism. How do DNA molecules express the genetic information they contain?
by breaking down proteins within the cell
by directing the process of protein synthesis
by regulating the storage of cellular proteins
by controlling the movement of protein molecules
In Texas Longhorn cattle, coat coloration is an inherited trait. What is the genetic basis of coat-color variation in Texas Longhorn cattle?
Differences in the nucleotide sequences of genes
Differences in the numbers of chromosomes in cells
Differences in the diets of individual cattle
Differences in the environmental conditions of different geographical areas
Label the diagram
AUG codes for the amino acid Methionine and AAA codes for Lysine in cucumbers. What do those two codons code for in birds?
Valine and Aspartic Acid
Serine and Glutamic Acid
Isoleucine and Histadine
Methionine and Lysine
Using the Codon chart attached, drag and drop the corresponding amino acid to its mRNA base
AAA : (a)
GUU : (b)
UAA : (c)
AGU : (d)
Which type of mutation is represented in the image?
a point mutation
an inversion mutation
a deletion mutation
an insertion mutation
Which type(s) of mutations will most likely change sequence of nitrogen bases in a codon?
Insertion
Substitution
Deletion
Translation
Label the diagram
Each cell in the human body, with the exception of gametes, contains the same number of chromosomes and the same genetic sequences. Which process determines cell differentiation or cell specialization?
Gene Expression
Mutation of the Genes
Different methods of cell division
the host chooses
