Protein. Carbon, nitrogen, oxygen, hydrogen, sometimes sulfur.
Nucleic Acid. Carbon, nitrogen, oxygen, phosphorous, hydrogen.
Explanation:
Organic means that biological macromolecules contain carbon. They may also contain hydrogen, oxygen, nitrogen, phosphorus, sulfur, and other minor elements.
What are biomolecules?A biomolecule, also known as a biological molecule, is any of the synthetic substances created by cells and living creatures.
Biomolecules come in a variety of sizes and constructions, and they serve a wide range of functions. Carbohydrates, lipids, nucleic acids, and proteins are the four major types of biomolecules.
Biomolecules are chemical molecules that are required for life to exist. These molecules serve critical roles such as a source of energy, materials for constructing new body mass.
Including such muscles, and other molecules that serve important functions such as hemoglobin, which transports oxygen in the blood.
Organic refers to the presence of carbon in biological macromolecules. They may also contain minor amounts of hydrogen, oxygen, nitrogen, phosphorus, sulfur, and other elements.
Thus, these are the elements that make up biomolecules.

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.

Explain the process of nuclear fusion. How many hydrogen atoms combine to form a single helium atom?
Answer:
The Hydrogen Fusion Process In the basic Hydrogen fusion cycle, four Hydrogen nuclei (protons) come together to make a Helium nucleus. This is the simple version of the story. There are actually electrons, neutrinos and photons involved that make the fusion of Hydrogen into Helium possible.
Explanation:
Answer:
This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy

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:
How are mutations and natural selection related?
Answer:
The genetic variation that occurs in a population because of mutation is random — but selection acts on that variation in a very non-random way: genetic variants that aid survival and reproduction are much more likely to become common than variants that don't. Natural selection is NOT random!

The process whereby plants capture energy and make complex carbon based molecules is known as
a. photosynthesis.
b. development.
c.evolution.
d. homeostasis.
Answer:
I'm not exactly sure cause I learned this along time ago, but I think its D.
Explanation:
Evolution is not accurate, and development has nothing to do with creating energy or making complex carbon. Photosynthesis seems like the right answer but that's when a plant absorbs sunlight and water to make glucose and oxygen.

Which statements describe the breakdown of lipids?
-The enzyme is a catalyst
-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

Explanation:
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

What is true about the molecules shown in the models? A. They are molecules of the same substance. B. They are molecules of two substances with the same properties. C. They are molecules that join together. D. They are molecules containing the same kind of atoms.
Answer/Explanation:
CO and CO2 are both carbon poisoning. They both are odorless, colorless, and potentially deadly. But the chemical difference(extra oxygen molecule) causes it to be a different substance. CO is carbon monoxide while CO2 is carbon dioxide. CO2 is common because it is what we exhale after a breath, it is used to keep plants alive. On the other hand CO is caused by gas emissions and lack of oxygen. They may sound the same but they are just two different molecules containing the same types of atoms.

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"

Which color on the image of the periodic table
corresponds with the transition metals.
Blue
Red
Black
Orange
So yellow is mostly the classification of Metal, But I don't see that option here. Answer-Blue
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.
