Answer:

The cell structures that are common to all cells include the DNA or the genetic material; the cytoplasm, which is the fluid where the organelles are suspended in it; plasma membrane, also referred to as the cell membrane that serves as the cell's barrier to the external environment; and the ribosomes, which are the organelles in charge of producing proteins

Answer:

i think its carbon dioxide.but not sure

Explanation:

remembering from like 3 months ago

Answer:

D. Carbon Dioxide

Explanation:

It is D. because trees absorb carbon dioxide and release oxygen into the air. So with out the tree's the Carbon Dioxide levels increase because there is nothing to absorb it.

Answer:

The correct answer is -

ADP has less potential energy than ATP

ADP can be created when an ATP breaks or releases a phosphate bond.

Explanation:

ADP is adenosine diphosphate which means adenosine bound with a sugar molecule and two groups of phosphate molecules that also play an important role in cellular energy flow like ATP.

In ATP, there are three phosphates and two high energy bond that provides much energy in breaking whereas, in ADP, only one high energy bond and two phosphates present there.

When an ATP molecule breaks or releases one of its Phosphoanhydrous bonds and release energy and one of the phosphate groups, adenosine diphosphate or ADP created.

The answer is: Both of them are False

Explanation:

Cytoskeleton helps the cells to maintain its shape and size, due to this they are like the girdles and beams of a warehouse.  

• A composition within the cell, which helps the cell to maintain their internal organization and shape is known as the cytoskeleton.  

• It also provides mechanical support, which allows the cells to perform essential activities like movement and division.  

• In the eukaryotes, the cytoskeleton within the cell is formed of filamentous proteins.  

• The three prime classes of elements, which differ in size and in composition of protein forms the cytoskeletons.  

• These are microtubules, actin filaments, and intermediate filaments.  

Thus, due to the properties of the cytoskeleton, they can be considered as the girders and beams of a warehouse.

Answer:

Explanation:

The major problem with this experiment is that he should have had a constant variable (in the form of the surrounding temperature) for his groups. Meaning, he should have had both groups planted in full sunlight and/or a shadier location since his prediction was on water intake by the plant and not the surrounding temperature.

The independent variable here is the type of soil (moist and dry) used while the dependent variable here is the time it took the fruit to develop and ripen on the plants in each garden location.

NOTE:

Independent variable can be described as the variable that is not dependent on any variable in the course of an experiment. It is also changed by the researcher during the course of the experiment.

Dependent variable can be described as the variable that is been tested during the course of the experiment.

Answer:

Calcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys. Calcium is essential to all living things, particularly for the growth of healthy teeth and bones. Calcium phosphate is the main component of bone. The average human contains about 1 kilogram of calcium.

Explanation:

Answer: Climate change would affect the ocean ecosystem, when heat rises due to greenhouse gases, the ocean would absorb more heat, which can result an increase temperature on the ocean's surface.

Answer:

The oceans are absorbing more heat, resulting in an increase in sea surface temperatures and rising sea levels.

Answer:

Karl von Frisch is best known for two major discoveries about honey bees. First, he demonstrated that honey bees have color vision, and published these findings in 191*. Second, in 193* he showed that honey bees use a dance language to communicate food locations to other bees.

Explanation:

Figure 1. Grids for the color vision test. The training color, marked with T, is blue in both cases; all other squares are shades of gray. The left box shows how the grid appears to an animal with color vision. The right box shows how the same grid may appear to an animal without color vision. The training square appears to be the same shade of gray as other squares in the grid. If the test animal cannot see in color, it will confuse the training square with other squares matching its shade of gray.

This clever test for color vision can be applied to any animal which can learn to recognize a feeding station using visual patterns.

The dance language

von Frisch observed that once one honey bee finds a feeding station, many other soon appear at the same station. This suggests that the first bee recruits other bees to the food. How might honey bees recruit help in collecting food? von Frisch¹s discovery of the dance language of the honey bee required careful determination of the correlations between movements of bees inside the hive and the locations of feeding stations. He found two types of dance. The round dance (Figure 2A) causes bees to look for food a short distance (up to about 50 meters) from the hive. The waggle dance (Figure 2B) tells bees the direction and distance to fly to find more distant food sources. Scout bees use these dances to recruit assistance in collecting food resources.

Answer:The short film Some Animals Are More Equal than Others: Trophic Cascades and Keystone Species opens by asking

two fundamental questions in ecology: “What determines how many species live in a given place? Or how large

can each population grow?” The film then describes the pioneering experiments by Robert Paine and James Estes,

in the 1960s and 1970s, which started to address them. Paine’s experiments on the coast of Washington state

showed that the starfish is a keystone species, having a disproportionately large impact on its ecosystem relative

to its abundance. Estes and colleague John Palmisano discovered that the kelp forests of the North Pacific are

indirectly regulated by sea otters, which feed on sea urchins that consume kelp. The presence or absence of sea

otters causes a cascade of direct and indirect effects down the food chain, which in turn affect the structure of

the ecosystem. These early experiments inspired countless others on keystone species and trophic cascades in

ecosystems throughout the world.

Level 4 responses should show potato/food arrows entering the mealworm, feces (and possibly urine) arrows leaving the mealworm and CO2 arrows leaving the mealworm.

Level 2 or 3 responses may show a variety of forms of matter without focusing specifically on molecules containing carbon atoms.

Energy Change: Explain your ideas about energy changes that are taking place inside the mealworms.

Level 4 responses should describe chemical energy moving from the potato into the mealworm and possibly chemical energy in the feces leaving the mealworm.

Level 2 or 3 responses may show a variety of forms of energy without focusing specifically on molecules containing high energy carbon bonds.

Answer:

Binomial nomenclature is basically the scientific classification of organisms, or taxonomy, using a latin name. It uses the genus and the species. For instance, the bacteria Staphylococcus aureus uses binomial nomenclature because Staphylococcus is the genus, while aureus is the species.

Biology Dictionary states, "The genus name is also called the generic name and always begins with a capital letter. For example, binomial name for cats is Felis catus. The genus name must be unique within each kingdom (see image below) but the same genus can be used in more than one kingdom. [. . .] The species within the genus is known by other names depending on the discipline. For general usage, the species is also called the specific descriptor. In botany, it is called the specific epithet and specific name in used in zoology. A species name can be used more than once within a kingdom.The species name always begins with a lower case letter. It can be a noun or an adjective and it must agree with the Latin gender of the genus name; masculine, feminine or neuter. For example, if the gender of the genus is masculine, the species name should end in -us, -a or -um. An example of this is Passer domesticus, the house sparrow, in which Passer has a masculine gender. Endings for feminine species names include -is and -e and -or is used for neuter genders."
