________ proteins or channel proteins are used to aid substances across the cell membrane in passive transport
Answer: channel proteins
Explanation:
Water channel proteins (aquaporins) allow water to diffuse across the membrane at a very fast rate. Ion channel proteins allow ions to diffuse across the membrane. A gated channel protein is a transport protein that opens a "gate," allowing a molecule to pass through the membrane.

Write a grammatically correct sentence that compares the reactants and products of photosynthesis with the reactants and products of respiration.
Answer:
The reactants needed for respiration are produced during the photosynthesis process, while the products of the respiration process are used during photosynthesis
"The reactants needed for respiration are produced during the photosynthesis process, while the products of the respiration process are used during photosynthesis" is a grammatically correct sentence that compares the reactants and products of photosynthesis and respiration.
Photosynthesis and respiration depend on one another as products of photosynthesis act as reactants in cellular respiration, whereas products of cellular respiration react as reactants of photosynthesis.
Photosynthesis:
Photosynthesis is the process takes place in green plants that produce sugar molecule and oxygen by reacting carbon dioxide and water in presence of the light. Energy (sunlight), H₂O, and CO₂ are reactants of this process that come from respiration. Sugar and O₂ are released as products that use in cellular respiration as reactants.Cellular respiration:
Process of cellular respiration use sugar molecule and oxygen to react together to form energy in the form of ATP by releasing carbon dioxide and a water molecule. Sugar and O₂ are reactants of this process that come from the photosynthesis process. Energy (ATP), H₂O, and CO₂ are released as products that use in photosynthesis as reactants.Thus, the grammatically correct sentence "The reactants needed for respiration are produced during the photosynthesis process, while the products of the respiration process are used during photosynthesis"

The enormous genetic diversity of HIV is largely the result of its______, and it has made it especially difficult to create a(n) ________ against the virus.
A. high mutation rate; antibiotic
B. high mutation rate; vaccine
C. low mutation rate; antibiotic
D. low mutation rate; vaccine
Answer:
B. high mutation rate; vaccine
Explanation:
The enormous genetic diversity of HIV is largely the result of its high mutation rate, and it has made it especially difficult to create a vaccine against the virus.
This ultimately implies that, the high mutation or replication rate of the human immunodeficiency virus (HIV) owing to its enormous genetic diversity has made it extremely difficult to develop an effective and accurate vaccine against the virus.
Hence, the human immunodeficiency virus (HIV) possesses a high error rate

Which evolutionary mechanism increases inheritable variations
Answer: Natural Selection. Natural Selection leads to an evolutionary change when some individuals with certain traits in a population have a higher survival and reproductive rate than others and pass on these inheritable genetic features to their offspring.
Explanation:
A new pest is found that only feeds on corn plant leaves. Livestock eat corn cobs. Which promoter would you choose if the modified gene produces toxins that are not safe for livestock to ingest?
Answer:
Promoter 2
Explanation:
Promoter 2 is the best choice because the resistance gene will only be expressed in the leaves of the corn plant. Promoter 3 only expresses genes in the corn roots, so the toxin would not be available in the leaves for the pest to eat. Promoters 1 and 4 would express the resistance gene in the leaves of the corn plant, but the toxins would be expressed in the corn cobs as well, which may then be fed to livestock.

-The name of the enzyme is lipase
-The enzyme speeds up the reaction
-The enzyme is made of RNA molecules
-The enzymes is degraded in the reaction
-The enzyme is involved in an anabolic reaction
Answer:
I think the second one
The name of the enzyme is lipase
Explanation:
because enzyme is a catalyst not because of breakdown of lipids but because it speeds up the biochemical reaction
this is a fact that enzyme speeds up the reaction.it is not because of lipids
enzymes is not degraded in the reaction.
anabolic reactions are the reactions that synthesizes larger molecules to smaller ones, not related to breakdown of lipids.
enzymes is not made up of RNA molecules. They are made up of proteins

Blue color of the periodic table image represent transition metal. Thus, option A is correct.
What are transition metal ?The metal which have valence electrons that can participate in the formation of chemical bonds called as transition metal.
In a periodic table the position of transition metal is the long middle portions of the periodic table and form Groups 3 elements through 12.
These are paramagnetic metals, a good conductors of heat and electricity, in a solution their compounds are brightly colored when hydrated.
Every transition metal has multiple positive oxidation states, hard solid with high melting points and boiling points.
The elements are dense, less reactive but are good catalysts which form complexes with molecules called ligands.
Transition metal ions have incomplete filled d-orbitals, except for scandium
Some of the transition metals are iron, chromium, vanadium, titanium, cobalt, nickel, tungsten, gold, and platinum.
Thus option A is correct.
