Which of the following describes the order in which traits and practices evolved in human ancestors?
A. bipedalism, tool use, large brains, modern behavior.
B. large brains, bipedalism, tool use, modern behavior.
C. large brains, tool use, bipedalism, modern behavior.
D. tool use, bipedalism, large brains, modern behavior.
E. bipedalism, modern behavior, large brains, tool use.
Answer:
The order of development has been large brains, bipedalism, tool use, modern behavior.
Explanation:
A is not correct because the human ancestors had large brains before they become bipedal, which is not weird considering the fact that all primates have proprtionately large brains, even for mammals.
B is correct because the large brains were already a trait of the human ancestors, with the change of environment they developed bipedalism, with the further growth of the brain and anatomic changes in the fingers the humans developed tools, and last but not least came to modern behavior.
C is not correct because bipedalism occurred before the usage of tools.
D is not correct because the tool usage did not occur at the beginning of human evolution, but several million years later.
E is not correct because the bipedalism occurred later than the large brains, and the modern behavior came the last, not in the early stages.

Why do roadside plants die frequently after salt trucks salt the roads?
A. Plants lose water to the soil because there is more water there
B. Plants can't take up water in their roots because the solute balance is "off"
C. All of these
D. Plants don't like salt, but take it into the roots anyway
Answer:
B.
Explanation:
Nature loves balance
due to the salt, and inbalance the plant will die of dehyration, same as people drinking sea water
Plants can't take up water in their roots because the solute balance is "off" so roadside plants die frequently after salt trucks salt the roads
How does plant take up water from soil ?
Osmosis is the process by which water moves into the roots of plants. The amount of salts in the water in the plant and the water in the soil determine how much water moves into the roots.Water may flow back into the soil from the plant roots if the salt level in the soil water is too high. The plant becomes dehydrated as a result, decreasing its yield or even dying.Even though the effects of salinity may not be obvious, crop yield losses may occur. The capacity of a particular crop to extract water from salinized soils determines its salt tolerance.By interfering with nitrogen uptake, reducing growth, and stopping plant reproduction, salinity affects crop, pasture, and tree production.The plant becomes poisoned and dies as the concentration of some ions, like chloride, that are toxic to plants rises.The salinization of rivers that were previously clean is dryland salinity's most significant off-site effect. This has serious financial, social, and environmental repercussions for both urban and rural communities, affecting the quality of water used for drinking and irrigation.The taste of drinking water may be affected by high salt concentrations. Particularly chloride has a low taste threshold. The levels of sodium and magnesium sulfate in drinking water may cause constipation and make it less suitable for grazing animals.

occurs during
the G1 phase
the S phase.
O the G2 phase.
mitosis.
Answer:
Rapid cell growth in preparation for cell division occurs during the G₁ phase.
Explanation:
G₁ phase is the first of three phases into which the interphase is divided and corresponds to the phase where rapid cell growth, molecule and organelle synthesis occurs prior to cell division.
The interphase is a resting or non-dividing phase of the cells, where preparation events occur prior to the M-phase or division.
Regarding other options:
In the S-phase of the interface, DNA replication occurs. Phase G₂ completes cell growth, with organelle and protein synthesis. Mitosis or M phase is the cell division.Answer:G2

Which of the following functions does active transport perform in a cell?
Distributing enzymes throughout the cytoplasm
Packaging proteins for export from the cell
Moving substances against the concentration gradient
Equalizing the concentration of water inside and outside the cell
Answer:
fourth option (D)
Explanation:
Equalizing the concentration of water inside and outside the cell
Active transport has been defined as the movement of ions and molecules at the expense of energy. "They move the substances against the concentration gradient." Thus, option C is correct.
What is active transport?Active transportation has been defined as the process that moves substances across the plasma membrane of the cell. It uses enzymes and cellular energy to drive the ions and molecules in and out of the cell.
The active transport has been moving the ions from the region low in the electrochemical gradient towards the region that is higher in solute concentration. It moves the substance against the gradient (lower to higher). It uses ATP to move the ions through the protein pump.
Sodium-potassium pump is the best example of the active transport that transports the potassium ions inside the cell and the sodium towards the exterior of the cell. It uses ATP as the fuel that moves ions against the gradient.
Therefore, option C. the active transport moves the ions and molecules from lower to higher solute concentration region.

White blood cells engulf bacteria through what process?
Answer:
Phagocytosis
Explanation: Phagocytosis occurs in the scavenging white blood cells of our body. They prowl around looking for invading bacteria and viruses which they engulf and destroy. Pinocytosis ("cell drinking") is almost the same process as phagocytosis, except it involves liquids instead of solids.
What estimated impact on energy use of food production would the water table in the valley that is pumped for irrigation falls, and water must now be pumped twice the depth to irrigate crops, does it increase or decrease and why?
Answer:
Irrigated agriculture constitutes the largest consumer of freshwater in the Mediterranean region and provides a major source of income and employment for rural livelihoods. However, increasing droughts and water scarcity have highlighted concerns regarding the environmental sustainability of agriculture in the region. An integrated assessment combining a gridded water balance model with a geodatabase and GIS has been developed and used to assess the water demand and energy footprint of irrigated production in the region. Modelled outputs were linked with crop yield and water resources data to estimate water (m3 kg−1) and energy (CO2 kg−1) productivity and identify vulnerable areas or 'hotspots'. For a selected key crops in the region, irrigation accounts for 61 km3 yr−1 of water abstraction and 1.78 Gt CO2 emissions yr−1, with most emissions from sunflower (73 kg CO2/t) and cotton (60 kg CO2/t) production. Wheat is a major strategic crop in the region and was estimated to have a water productivity of 1000 t Mm−3 and emissions of 31 kg CO2/t. Irrigation modernization would save around 8 km3 of water but would correspondingly increase CO2 emissions by around +135%. Shifting from rain-fed to irrigated production would increase irrigation demand to 166 km3 yr−1 (+137%) whilst CO2 emissions would rise by +270%. The study has major policy implications for understanding the water–energy–food nexus in the region and the trade-offs between strategies to save water, reduce CO2 emissions and/or intensify food production.

Which organism should have the largest population, and why?
Answer:
i think it is the cells
Explanation:
When is it appropriate to use a line graph, bar graph and a pie chart?
Answer:
When your graphing to data from an experiment.
Explanation:
You use any type of graph when you're doing an experiment because, in the beginning, you start by marking where you started then as time goes on you mark it accordingly. For example, say your starting at 5cm on a plant so on the line/bar graph you make 0 you 5 since that is where you're starting at. when you water the plant you decide to give it 10cm of water and put it in the sun constantly. A week later of sun and water it grew 10cm, so you mark it on your line/bar graph to show how much it grew over time. Make a little bit more sense?
If you buy two plants of the same species that have the same-colored flowers, they must have different genotypes. True or false and why
Answer:
False
Explanation:
They are displaying the same phenotype. That doesnt mean they have the same genotype.
For example lets say the plants colours are purple (P)
one plant may have the geneotype of PP, (two dominant purple coloured alleles), the other plant may have the genotype Pp, (one dominant purple allele and one recessive allele for another colour lets say pink). Because purple (P) is the dominant allele they are both the same colour displayed but they have different genotypes.
The statement "two plants of the same species that have the same-colored flowers, they must have different genotypes" is definitely true.
What is Species?Species may be defined as collections of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. These individuals actually or potentially interbreed in nature. In this sense, a species is the biggest gene pool possible under natural conditions.
When two plants of the same species have the same-colored flowers, it means that they have the same phenotypes. But it does not mean that they possess similar genotypes.
For example, one plant may have the genotype of homozygous dominant (PP), and the other plant may have the genotype heterozygous dominant (Pp). This is both cases the genotypes are different and the phenotypes are the same.
Therefore, the statement "two plants of the same species that have the same-colored flowers, they must have different genotypes" is definitely true.

what factor will most likely decrease the rate of glucose production
Hello. This question is incomplete. The full question is:
What factor will most likely decrease the rate of glucose production?
A. decreasing in availability of oxygen B. decreasing in availability of carbon dioxide C. increase in availability of water D. decrease in plant-eating organisms
Answer:
B. decreasing in availability of carbon dioxide
Explanation:
According to the answer options, we can say that this question is related to the formation of glucose through photosynthesis, which is the process that uses carbon dioxide and water to generate glucose. In this case, we can confirm that for the photosynthesis process to occur fully and the plant to achieve a large glucose production, a large availability of water and a large availability of carbon dioxide are required.
Therefore, we can conclude that a decrease in the availability of carbon dioxide would decrease the production of glucose.
