Which of these statements expresses a scientific theory?
O A. Any cell that contains a nucleus is usually larger than any cell
without a nucleus
O B. A material that consists of one or more cells is a living organism.
O c. All living organisms have a body that consists of one or more
cells.
O D. A study of material found on a beach showed the presence of

Answer:

C is a dominant allele, c is recessive. Cc is heterozygous dominant.

Given Proposition: The Shark Population has increased. This is assuming that we only base it off of the given food tree, rather than using the food web, which is more factually correct. This means that the sharks in the area can only eat sea otters, and that sea star populations and sea otters can only eat clams.

1) In this case, the shark population increases. This generally means that the sea otter population by itself has increased, suggesting a positive net change within the given food chain. However, with increased shark populations, would mean a damage to the amount of sea otters in the area. This can create an underpopulation of sea otters, which, if sea stars were not a factor, can mean a increase of clam population.

However.

2) Sea stars are a part of the food chain given. Therefore, it can be suggested that while the sea otter population may stabilize and/or diminish, the sea star has no "predator". This means that with the decrease of the sea otter population, the sea star population may actually grow, as the competition for the same source diminishes. Again, with the demand taking over the need, the sea star population may fall once again due to overfeeding, and essentially starvation.

In essence:

Shark Population: Increased

Sea Otter Population: Decreases (is eaten)

Therefore, Clam Population is speculated to increase.

However, the Sea star population would thereby increase due to having more food.

A larger sea star population in which the clam population cannot sustain would collapse, leading to a fall.

Also, due to the smaller amounts of sea otters in the area, the shark population may also see to an decrease of population, as they die from starvation.

The sea otter population would then stabilize when the predatory amounts or less, and their competition collapses.

Of course, there will always be a "food web". Sea otters do not solely rely on clams, neither do sharks solely rely on otters.

Answer:

Yes, I think so

Explanation:

I think yes because if the father has Type O but the mother has Type AB then,  I suppose yes. However the alleles would be ABO...I'm not very sure.

"How are ABO alleles inherited by our children? Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter."

Answer:

The entire system changes or could stop working.

Explanation:

When one part of the system changes, it may affect the entire system with a systematic consequence of the effective operation of the system.

A system may be defined as the arrangement of things or objects that are gathered together and working as parts of a mechanism or an interconnecting network.

When any alteration will be made at any part of the system, it may affect the working of the whole system with respect to the type of alteration made.

Sometimes, this alteration is also responsible for the termination of the entire system.

Therefore, it is well described above.

Answer:

Parent material is the underlying geological material (generally bedrock or a superficial or drift deposit) in which soil horizons form. Soils typically inherit a great deal of structure and minerals from their parent material, and, as such, are often classified based upon their contents of consolidated or unconsolidated mineral material that has undergone some degree of physical or chemical weathering and the mode by which the materials were most recently transported.

Answer:

C

Explanation:

there are planets made of ice, rock and gas

All the planets have atmospheres, are made of rock of gas, and some have moons or rings.

• It is to be noted that in the solar system every planet exhibits an atmosphere of one kind or another. It can range from tenuous and thin like of mercury to the incredibly powerful and dense like that of the gas giants.

• The inner planets of the solar system, that is, the Earth, Mercury, Venus and Mars are made of rock, while the giant planets are not solid, they are mainly formed of hydrogen and helium. They are also known as gas giants.

• All the planets have moons except Venus and Mercury, and Saturn possess rings also.

Thus, the correct answer is option D.

B. Plankton are a food source for humans

Plankton is food for many small fish. With the abundance

of Plankton, these fish can thrive. When these smaller fish thrive they are food to bigger fish that we eat. Since the smaller fish thrive then the bigger fish that we eat also thrive. This makes bigger fish an abundant food source due to plankton supporting the smaller fish and other organisms.

Answer:

Hox genes control the timing of development and growth of embryos. Organisms A and B have very similar Hox genes, and their embryos, in the earliest stages of development, are also very similar.

Explanation:

Hox genes are a family of transcription factors that play a critical role in the development of the body plan during embryogenesis by controlling the spatial patterning of the developing embryo.

Hox genes play a critical role in embryological development by controlling the formation and patterning of the body segments in animals. These genes are responsible for specifying the identity of different regions of the body, such as the head, thorax, and tail, during the early stages of development. They do this by regulating the expression of other genes that control the differentiation and growth of cells in specific regions of the embryo.

Hox genes are arranged in clusters on chromosomes and are activated in a specific order along the anterior-posterior (front-to-back) axis of the developing embryo. This sequential activation pattern helps to establish the body plan and shape of the organism. For example, the Hox genes that are activated in the head region will determine the formation of the head and brain, while those activated in the thorax region will control the formation of the heart and lungs.
