Answer:

D

Explanation:

According to the kinetic theory of matter, option D. all the particles that make up a substance are constantly in motion.

The Kinetic Theory of Matter states that all matter is made of particles that are atoms and molecules that are constantly in motion in the substance, therefore, particles of all matter have kinetic energy.

Thus, the correct answer is - option D. all the particles.

Explanation:

Answer:

rhe answer is that the rocks of that time are buried deeply under the soil.

The factor that prevents us from finding fossils from the Precambrian era is that life-forms in this era had no skeletons.  Therefore, option (A) is correct.

The Precambrian era spans from the formation of Earth about 4.6 billion years ago to the start of the Cambrian period about 541 million years ago. During this time, life on Earth consisted mainly of simple, single-celled organisms such as bacteria and algae.

These organisms lacked the hard shells, bones, and other structures that are typically preserved as fossils. Therefore, the fossil record from the Precambrian era is relatively sparse, consisting mainly of impressions and other traces left by these early organisms in sedimentary rocks.

Answer:

The cell cycle can be thought of as the life cycle of a cell. In other words, it is the series of growth and development steps a cell undergoes between its “birth”—formation by the division of a mother cell—and reproduction—division to make two new daughter cells.

Answer: You picked the correct answer, "They all inherited their traits from a common ancestor."

Explanation: Well, one I had a test on this question too and I got it right. Second, if all species shown have something in common (structures) than they most likely got it from a common ancestor.

They all inherit their traits from a common ancestor. So, the correct option is C.

An ancestor is a parent or the parent of an antecedent, commonly referred to as a forefather, fore-elder, or forebear. Each individual from whom one is born is an ancestor. The individual who has received an estate, according to law.

Anybody we are descended from is an ancestor. To descend in a family implies to "come from." The parents, who in turn descended through their parents, who in turn descended from the parents, and so forth. The ancestors are the line of parents and kids.

Your ancestors are your mother, father, and grandparents. If matrilineal descent is practiced in the culture or civilization, your mother and grandmother are the ancestors but not your dad or grandfather. They all derive their characteristics from an in this instance.

Therefore, the correct option is C.

Answer:

Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

Answer:

1. Only small uncharged molecules can diffuse freely through phospholipid bilayers (Figure 2.49). Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes. 2. Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). 3. Objects change their motion because unbalanced forces act on them. There are four main factors that affect the motion of objects. These factors are force, friction, inertia, and momentum.

Explanation:

Hope this helps. ^_^

Answer:

Examples include steroids and Vitamins

Phospholipids ,as the name implies fall under the category of lipids. Phospholipids have a hydrophilic "head" which has a strong attraction to water molecules.The hydrophilic head contains a phosphate group which allows for reactivity with water molecules.

Phospholipids also contains two hydrophobic "tails" which has a strong repulsion to water. The tails are derived from fatty acids and are joined by a glycerol molecule. These compounds are less reactive to water molecules .

These properties make phospholipids to be soluble in both water and oil which favors the movement of molecules such as Steroids and Vitamins in and out of the cells through the process called Diffusion.

The direction of movement depends on the concentration of molecules as they usually move from a region of high concentration to a region of lower concentration to ensure there is equilibrium and proper functioning of cells.

D. An organism's phenotype is only made up of genes and alleles.​​​​​​​

An organism's phenotype is only made up of genes and alleles is the false statement about genotype and phenotype.Therefore, the correct option is D.

Genotype refers to the genetic makeup of an organism, including all of its inherited genes and variations. Phenotype refers to the physical characteristics and traits of an organism that result from both its genetic makeup (genotype) and environmental factors.

The given statement is false because an organism's phenotype is not only determined by its genes and alleles, but also by environmental factors such as diet, exposure to sunlight, and other external factors.Therefore, the correct option is D.

Answer:

The correct answer is - option B. laws that improve air quality and restrict pollution.

Explanation:

The dark peppered moths were the adaption of the light peppered moths due to the change in the environmental condition of increased pollution that made tree bark dark in color and allows birds to easily prey on the light peppered moths.

This leads to natural selection and light moths become dark but the after Clean Air Act was that there was less pollution then there is less soot in the air, so trees were less black which result in the Light-colored moths would increase, and dark-colored moths would decrease.

Answer:

decreases a plant’s weight

Explanation:

Aerobic respiration is a process of respiration in which oxygen is required and the byproducts of aerobic respiration are carbon dioxide, water and energy.

Plants undergo aerobic respiration and it is a catabolic process in which complex compounds in plants turns into simpler compounds. This process reduces the dry weight of the plants.

Glycolysis is the first step in both aerobic and anaerobic respiration so it is not a typical aerobic respiration.

Hence, the correct answer is "decreases a plant’s weight".

Answer:

B) In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.

Explanation:

CORRECT

The best statement for law of Superposition is in undisturbed layers of sedimentary rock, the lowest layers contain the older rocks. Thus option B is correct.

Law of superposition stated that a key stratigraphic concept indicating that within a sequence of sedimentary rock layers, the oldest layer is at the bottom and the layers are increasingly younger with ascending order in the sequence.

Superposition is defined as the ability of a quantum system to exist in numerous states until it is measured.

It can also be stated that an assumption that serves as a foundation for the sciences of geology, archaeology, and other fields concerned with geological stratigraphy.

Thus, the best statement for law of Superposition is in undisturbed layers of sedimentary rock, the lowest layers contain the older rocks. Thus option B is correct.
