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.

GOOD LUCK! ;-)

Answer:

Option B . Chemosynthesis and Marine snow.

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.

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.

Answer:

The energy from the sun is absorbed by chlorophyll and turned into chemical energy in the form of electron carrier molecules called ATP (Adenosine triphosphate) and NADPH.

Explanation:

Answer:

The answer is C, the sun's rays cause mutations in the skin cells.

Explanation:

Answer:

B. The heat from the sun interrupts the cell cycle

Explanation:

Too much UV radiation from the sun or sunbeds can damage the genetic material (the DNA) in your skin cells. If enough DNA damage builds up over time, it can cause cells to start growing out of control, which can lead to skin cancer.

Answer: boron has 5 protons and 6 neutrons

Explanation:

According to the periodic table, the model of an atom that describes an atom of boron is model A. Boron has 6 neutrons and 5 protons.

The chemical elements are arranged in rows and columns in the periodic table, also called the periodic table of the elements. It is frequently used in physics, chemistry, and other sciences, and is frequently regarded as a symbol of chemistry.

The atomic number is the number of protons, which is characteristic of a chemical element. The atomic number increases from left to right in the Periodic table.

Boron is an element with atomic number 5, which means it has 5 protons and 5 electrons, boron atom has a neutral charge.

The electron configuration of boron: ₅B: 1s² 2s² 2p¹, it has three valence electrons in 2s and 2p orbitals.

Therefore, the correct option is A, model A. Boron has 6 neutrons and 5 protons.

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!

Answer:

he produced a true-breeding parent generation, then a second generation by breeding two different true-breeding plants, then a third one by self pollinating the plants in the 2nd generation that had similar traits

Explanation:

Answer:

Carbohydrate. Carbon, hydrogen, oxygen.

Lipid. Carbon, hydrogen, oxygen.

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.

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.

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:  

Cellular respiration:  

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"

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

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.

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.
