Answer:

when small molecules pass through the lipid bilayer of a cell membrane simple passive diffusion occurs

Explanation:

Diffusion is one form of passive transport that doesn't require the expenditure of cellular energy. A molecule can diffuse passively through the cell membrane if it's lipid-soluble, uncharged, and very small, or if a carrier molecule can assist it. ... The assisted process is known as facilitated diffusion.

Answer:it was heated and under pressure

Explanation:

Metamorphic rocks are formed from existing rocks, under high temperature and high pressure. This process is called metamorphism.

Metamorphic rocks are those rocks that are formed from different kinds of rock like igneous, sedimentary, or gneiss rock under high pressure and intense temperature. They are rigid in nature.

In the formation of metamorphic rocks, firstly existing rock is broken down into small particles by physical, chemical, or biological agents. The process of breaking down rock is called weathering.  Then erosion and transportation of these particles take place by the wind, water, or any biological agent.

The next step involves compaction after sedimentation. Thus, metamorphic rocks are formed from existing rocks.

Answer:

Postharvest physiology plays a fundamental role in extending the shelf-life and quality of plant products. An example of postharvest physiology methodologies is by reducing the temperature to improve shelf-life before consumption

Explanation:

Postharvest physiology refers to the methodologies used for extending shelf-life and quality, thus being a critical issue in food systems. Postharvest approaches include chemical treatments, temperature reduction, cleaning and disinfection methods, etc. Crop varieties are genetically selected in order to maintain nutritional qualities of stored seeds for a long time after harvest. These seeds are also controlled during storage by using postharvest handling practices (e.g., chemical and enzyme inhibitors that extend shelf life).

C. by radio observations of Jupiter's rapidly spinning magnetosphere

Explanation:

Jupiter refers to one of the planetary bodies in the solar system. It is considered to be the largest (twice as large or big as every other combined) planetary body and the fifth (5th) from the Sun.

Jupiter is a planet that rotates rapidly and as a result it is referred to as being noticeably oblate. It has the fastest rotation rate among the planets of the solar system because it completes a rotation about an axis in 9.9 hours.

The rotation rate of Jupiter's core was determined by radio observations of Jupiter's rapidly spinning magnetosphere.

Answer:

The correct answer would be - ions will move from solution 1 to solution 2 so the cell will shrink.

Explanation:

The concentration of CaCl2- = 200mM

CaCl2 dissociates in the three different ions in a solution and each has the same osmolarity

The concentration of glucose = 15 mM

So, the osmolarity of solution 1 would be:

3 × 200 + 15= 615 mM

Similarly, the osmolarity of the second solution would be

The concentration of NaCl = 140 mM

The concentration of glucose = 150 mM

NaCl dissociates in the two different ions in a solution and each has the same osmolarity

140×2+ 150= 430 mM

The solution has more concentration of ions than solution two so the movement of the calcium ion of the CaCl2- would be possible only and therefore, the cell in solution 1 will shrink.

Answer:

The answer is option A "A decrease in the kangaroo rat population will cause a decrease in the coyote population"

Explanation:

Climate is a significant ecological impact on environments. Changing Climate influences biological systems in an variety of ways. For example, warming may constrain species to relocate to higher scopes or higher rises where temperatures are more helpful for their endurance.

Environmental change not just influences biological systems and species straightforwardly, it likewise communicates with other human stressors, for example, advancement. Although a few stressors cause just minor effects when acting alone, their combined effect may prompt emotional natural changes. For example, environmental change may worsen the pressure that land improvement puts on delicate water front zones. Also, as of late logged forested zones may get defenseless against disintegration if environmental change prompts increments in substantial down pour storms.

Answer:

Nonsense mutation. A nonsense mutation is also a change in one DNA base pair. Instead of substituting one amino acid for another, however, the altered DNA sequence prematurely signals the cell to stop building a protein. This type of mutation results in a shortened protein that may function improperly or not at all.Sep 21, 2020

Answer:

Five different types of heterotrophs are carnivores, herbivores, omnivores, scavengers, and detritivores.

Carnivores eat the meat of other animals. Example: Bear

Herbivores eat vegetation. Example: Deer

Omnivores eat a combination of both meat and vegetation. Example: Humans

Scavengers eat things left behind by carnivores and herbivores. Example: Raccoon

Detritivores eat small bits of organic matter, such as soil. Example: Worms

Edit: If you'd rather substitute one of those for a decomposer, Decomposers break down dead or decaying organisms. Example: Mushroom, or fungi.
