Which of the three traits considered in this film (bipedality, extensive tool use, and large brains) were present in the 3.2-million-year-old Australopithecus fossil (Lucy)?.
Answer:
The bipedality
Explanation:
One of the things the discovered fossil signified was that human bipedality was more ancient than the large brain size because Lucy actually had a small skull which could indirectly be translated to small brain size.
NOTE: Bipedality can be described to mean the ability of an organism to move about with two legs. Hence, it must have been discovered that Lucy had two legs.
Which is one function of the nucleic acid
Answer:
The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins.

7. Chemical or physical factor that determines the number
of organisms in a population
Answer:INTERSPECIFIC COMPETITION
Explanation:
The physical factor that determines the number of organisms in a population is ; Interspecific competition
Interspecific competition in a population is a competition that exists between organisms of different species, while the competition that occurs within organisms of the same specie is termed intraspecific competition.
During Interspecific competition the different species compete for food, water and Habitat which every organism needs to survive, and in most cases the stronger specie overruns the weaker species and this will lead to the depletion in the number of the organisms of the weaker specie and an increase in the number of the stronger specie within the population.
Hence we can conclude that The physical factor that determines the number of organisms in a population is ; Interspecific competition .

1. Does a scientific theory ever become a law? Explain
the difference between scientific theory and law.
Answer:
a theory cannot become a law
Explanation:
the difference between a scientific theory and a scientific law because a theory is an in depth explanation of an observed phenomenon. a law is a statement about an observed phenomenon or an unifying concept (i.e.: newtons law or gravity - no explanation on how it works or what it is just that it exists.)
according to the diagram the temperature where clouds form is?
Answer:
higher than the temperature near mountains
Explanation:
Answer: C. lower than the temperature on the ground
Explanation: Because on the chart it shows the temp on the ground is 92° but then the temp where clouds form is 60°. This means that the temp at the ground is higher than the temp at 6000ft.
Which of the following statements describes in the correct order the events that may take place after an eastern forest burns down? Bare soil is exposed, weeds and grasses colonize, perennial plants are established, shrubs appear, trees appear, and forest results Bare soil is exposed, weeds and grasses colonize, perennial plants are established, shrubs appear, trees appear, and forest results Bare soil is exposed, perennial plants colonize, grasses and weeds are established, shrubs appear, trees appear, and forest results Bare soil is exposed, perennial plants colonize, grasses and weeds are established, shrubs appear, trees appear, and forest results Bare rock is exposed, lichens colonize, grasses are established, shrubs appear, and trees appear Bare rock is exposed, lichens colonize, grasses are established, shrubs appear, and trees appear Bare soils is exposed, shrubs colonize, trees appear, weeds and grasses are established and mature forest results
Answer:
Bare soil is exposed, weeds and grasses colonize, perennial plants are established, shrubs appear, trees appear, and forest results
Explanation:
This question describes a secondary succession, which is a colonization that occurs after a natural disaster has caused damage to an ecosystem. In secondary succession, SOIL, is already present, hence, there is rapid initial recolonization by GRASSES AND WEEDS.
The colonization of grasses and weeds is soon followed by the establishment of PERENNIAL PLANTS, after which SHRUBS appear, then TREES until a stable or climax ecosystem of FOREST results.
Why did people in England feel that it was reasonable that America paid more taxes?
Answer:
See below
Explanation:
The people in England felt that it was acceptable to make to colonists pay taxes because they felt that they still owned the colonists and could push them around as they wished. They also needed the money to pay for war debt. It was also a reaction to the protests that the Americans were performing.
The slow depolarization of the pacemaker cells is caused by the opening of the:_______.
Answer:
The slow depolarization of the pacemaker cells is caused by the opening of the non selective cation channels.
Explanation:
Pacemaker cells are specialized cardiac muscle cells with the task to create the rhythmic pulses that make the cardiac muscle contract properly, functioning as a whole and not as independent contractile cells.
One of the things that differentiate pacemaker cells from regular cardiomyocytes is that pacemaker cells slowly depolarize by themselves. This happens because when these cells are in phase 4, in a state of hyperpolarization, the 'funny current' appears to begin depolarizing the cell again.
Hyperpolarization usually occurs because there's an outflux of potassium ions (which makes the inside of the cell much more negative than the outside of the cell) but, in pacemaker cells, the membrane becomes less and less permeable to potassium, which ends up decreasing the outflux of this ion. Along with this change in potassium's electrical conductance, the funny current increases the permeability of sodium, which means that there's also a sodium influx happening at the same time, helping in the depolarization process.
This mixed sodium and potassium permeability is one of the key features of the funny current, and is possible thanks to the opening of non-selective cation channels in the membrane that allow the passing of any cation following their specific chemical gradients.

Light behaves in specific ways. It can be reflected, refracted, or absorbed, and under certain conditions, run into different kinds of interference. Which explanation best describes why light is refracted as it enters water?
A. The light bends when it enters water due to its reflection.
B. The speed of light remains the same as it moves from air to water, causing the light to reflect.
C. The speed of light increases when it enters a different medium, but it doesn't bend.
D. The speed of light changes as it moves from air to water, causing the light to bend.
Answer:
D
Explanation:
Refraction is generally defined as the change in the direction of a wave as it travels from one medium to another. Light is a form of wave and light refraction is caused by a change in the speed of light as it moves from air to water, causing the light to bend in the process. The medium of travelling has to be transparent.
The change in the speed and direction is due to the variability in the refractive index of media. Light travels faster as it moves from a medium of higher refractive index to a medium of lower refractive index and vice versa.
The correct option is D.
Gram , coccus, chains, catalase -, gamma hemolysis, glucose fermentation, grows slightly on MSA (salt tolerant) other test: mannitol fermentation test results: >80% which other test(s) are recommended to further increase the accuracy of your identification This organism is .
Answer:
The name of the test which can increase the accuracy of the identification of the organism is Coagulase testing.
Explanation:
Given the points stated in the question, the organism most likely under scrutiny here is Staphylococcus Aureus. Science has shown that it is the most harmful of all of the many different staphylococcal bacteria that there is.
The best test for differentiating and identifying Staphylococcus Aureus apart from other types of other Gram-positive cocci is the coagulase test.
The coagulase test checks to see if the microbe can produce an exoenzyme called coagulase.
Coagulase - an exoenzyme, is usually produced by bacteria. This enzyme triggers the coagulation of blood or plasma.
Only the pathogenic or disease-causing forms of staphylococcus can produce this enzyme. The enzyme is qualified by the suffice "exo" because the enzyme is secreted externally and not internally. Also, its functions are external, not internal.
The Coagulase testing is of two types:
The Slide TestThe Tube TestIt is usually safer to use the test tube method. If one must rely on the slide test, the results must be read quickly as it is prone to false positives.

What is wrong with this cell diagram ? (Giving brainliest)
Answer:
C
Explanation:
It has a round shape so obviously plant cell. You can see the vacuoles, mitochondria, and E.R., but it's missing its nucleus.
Answer:
D
Explanation:
A plant cell would have a cell wall to make the cell structured and more rectangular, so the other answer is incorrect. This is an animal cell. You can tell because there is no cell wall and the vacuoles are smaller (plant cells usually only have 1 large vacuole), and there are no chloroplasts. There is no nucleus pictured and since it is an animal cell, the cell doesn't need chloroplasts. That means that the answer is D.
