Explanation:

The statement that best describe the carbon cycle is a carbon source is a process that returns carbon to the environment. Thus, option C is correct.

The carbon cycle refers to the movement of this element (carbon) between biotic and abiotic factors. Carbon is a harmful greenhouse gas present in the atmosphere which is associated with climate change. A carbon source is a process that returns carbon to the environment and the carbon can be used only if large amounts of heat are added to a system that carbon sink is a process that stores carbon.

The carbon cycle shows the continuous movement of carbon atoms between the biosphere, atmosphere, hydrosphere, and geosphere. Some processes store carbon while others release it.Photosynthesis is a process in which carbondioxide gas that is present in the atmosphere moves into the plant body for the production of food in the presence of sunlight.

Therefore, The statement that best describe the carbon cycle is a carbon source is a process that returns carbon to the environment. Thus, option C is correct.

Answer:

Yes, Jamal’s respiratory system is working, but his digestive system is not breaking down starch molecules into glucose for his cells.

Explanation:

Jamal ate a meal of rice before seeing his doctor. Jamal has been feeling tired because his body cannot breakdown the starch molecules into glucose and thus has low levels of glucose in the blood.

A healthy diet is a diet which maintains or improves the overall health of an individual. A healthy diet provides the body with all the essential nutrients in sufficient amount. A healthy diet contains fluids, macronutrients such as protein, micronutrients such as vitamins with adequate amount of fiber and food energy.

Jamal is eating a meal of rice before seeing the doctor. He is feeling tired. After the test, it was observed that the oxygen level is normal however he has a low level of glucose. This is because rice contains high amount of starch, which is a polysaccharide of glucose. This starch is broken down by the body into glucose units which are used by the cells in producing energy. However, Jamal's body cannot break down this starch into glucose molecules and thus show low levels of glucose molecules.

The Hawaiian Islands are nearly entirely made of basalt lava, the most abundant type of rock on the planet.

Hot, molten rock crystallizes and hardens to produce igneous rocks, which are named after the Latin word for fire. The melt begins deep inside the Earth around hot regions or active plate borders, then it rises toward the surface. Depending on where the molten rock hardens, igneous rocks are classified as either intrusive or extrusive.

Thus, Hawaiian islands are made up of basalt ; the most common rock on the earth.

Explanation:

Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.

The law of conservation of energy says that energy is neither created nor destroyed but only converted from one form to another, such as from the kinetic to the potential and vice versa. Here, the ball is placed at the top, where it has no motion, but the ball has potential energy, and that potential energy gets converted into kinetic energy when the ball starts to roll down the hill. After sometime, the ball spontaneously stopped on the ground, and the kinetic energy was converted into potential energy.

Hence, Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.

Insular biogeography or island biogeography is a field within biogeography that examines the factors that affect the species richness and diversification of isolated natural communities. The theory was originally developed to explain the pattern of the species–area relationship occurring in oceanic islands.

The reptile population decreases as arthropods decrease with their habitat

Migrating species are more likely to find larger habitats over smaller ones. Explanation: The concept of island biogeographical model establishes that larger islands and habitats will have a larger number of species than a smaller island. Larger islands have more tendency to attract new species.The species–area relation, whereby the number of species in a spatial unit increases with that unit’s area, well predates the MacArthur and Wilson theory of island biogeography, having been documented for about 150 years. Two general kinds of models for this relation have been proposed. The first has number of species predicted from an assumed species–abundance distribution and the total number of individuals of all species combined (assumed proportional to area). The second develops species–area relations from MacArthur and Wilson’s species-equilibrium approach.

Claudius Ptolemaeus (85-165 AD) or Ptolemy believed Aristotle's theory that the Sun, Moon, and planets circled the Earth.

However, he improved it to account for the fact that planets sometimes appear to travel backward across the sky, called retrograde motion.

Galileo Galilei used various pieces of evidence to support Copernicus's heliocentric model and challenge the geocentric model proposed by Aristotle and Ptolemy. Some of the key evidence and observations that Galileo put forward include:

Thus, it's worth noting that while Galileo provided empirical evidence to support the heliocentric model, his ideas and evidence faced strong opposition from the religious and cultural beliefs of the time, as they contradicted the established dogma of a geocentric universe.

Because limiting factors affect plant growth

Explanation:

A limiting factor is a condition that limits the population's growth in an ecosystem by slowing or stopping its growth. These factors are generated by the lack or excess of a particular resource. In plants, limiting factors include, among others, light, water, temperature, oxygen, food, (i.e., nutrients and minerals), space, etc. In this case, the farmer must know which greenhouse conditions are limiting factors in order to ensure the survival and optimal development of the plant population.

stem cells are manipulated to specialize into specific types of cells, such as heart muscle cells, blood cells or nerve cells. The specialized cells can then be implanted into a person. For example, if the person has heart disease, the cells could be injected into the heart muscle.

Daughter cells are created when stem cells divide properly in the body or a lab to create more cells. These daughter cells either develop into fresh stem cells or into differentiated cells with a more specific role, such as bone, blood, brain, or heart muscle cells.

According to research, cardiomyocytes made from pluripotent stem cells can develop into beating human heart muscle cells that both produce the required signals and restore muscle lost during a heart attack.

Stem cells have the ability to multiply and develop into a variety of relatively mature cells. When inserted into a blastocyst, embryonic stem cells have the ability to develop into any organ in the human body.

Therefore, theoretically, every organ in the body might be replaced using embryonic stem cells.

There was more erosion in the Colorado Rockies scenario where there was steady rain compared to the scenario in the same area where there was only a drizzle. There is more erosion because the steady rain increased the volume of the river more than the drizzle did. Because there was more water added to the river, the river flowed faster. The faster a river flows, the more sediments it transports or erodes.

Endoplasmic reticulum, and ribsome

Both of them are in the production of proteins

Rough endoplasmic reticulum is a membrane-bound organelle that uses ribosomes on the membrane surface to carry out its function of producing proteins. Thus, option A,C is correct.

Generally speaking, the endoplasmic reticulum's function is to produce proteins that allow the rest of the cell to function. It can be smooth or rough.

These proteins are made by tiny, circular, elongated organelles called ribosomes, which are located on the rough endoplasmic reticulum.

On the rough ER, proteins are made. The ER receives those that have been processed translationally.

A signal peptide at the N terminus, which is recognized by a particular receptor (docking protein) on the ER membrane, is necessary for this insertion.

Therefore, both endoplasmic reticulum and ribosome are involved in the protein formation.
