If the spinach leaf disks were boiled before being tested, all the leaf disks would sink which is as a result of the lack of space for gases.
What is Sink?This is referred to as the condition in which a substance goes below the surface of a material and is usually in a submerged position due to some factors.
When the spinach leaf disks is boiled, gases form which are usually in the form of vapor and therefore gives rise to it sinking as a result of there not being space for them and the photosynthetic ability is greatly reduced which is therefore why it was chosen as the correct choice.

Why would it be useful for the SAME cell to be able to make different kinds of proteins at different times? Give an example, or make one up.
The cell is a complex system with specialized organelles and cellular machinery. The cell in an organisms have the same genetic material (DNA), but each cells only produce the proteins that they need in the moment or function that they are needed, that's because the cell have a "intelligent" intrecellular signaling and organization system. Some examples of these hability of the cells to control the production and liberation of proteins is the cell differentiation and the case of cells that have the function of producing protein hormones (insulin, glucagon, pituitary hormones, and hypothalamic hormones), it is important to the cells to have the control of which they produce because one cell have more autonomy and with only one genetic code an organism com be self-sufficient (molecular) and with internal protein variability.

Which of the following is NOT a hypothesis about why the gas planets have rings?A. A moon broke apart and the debris formed ringsB. Orbiting debris from the planet's formation did not have enough gravity to formmoonsC. Small pieces of the planet broke off and were kept in orbit
All the four gas giants have rings and moons. Being theorized that the rings of Uranus, Neptune, and Jupiter are probebly a result of a meteor impact on their tiny inner satellites, forming rocky debris and dust that conitues to orbit the planet, while Saturn rings are made mostly of ice. however there is many theories, making difficult to be sure how those rings are formed. Between the alternatives the only that is not a hypothesis for why the gas planets have rings is: " Orbiting debris from the planet's formation did not have enough gravity to form moons" (b).
How does contour plowing in farming help to prevent pollution?A. Contour plowing is used to reduce the amount of fertilizers used.B. Contour plowing is used to make insecticides less toxic.C. Contour plowing is used to reduce erosion and sediment pollution.D. Contour plowing is used to treat pathogens in livestock waste.
Plowing is a farming practice, that creates as its name says, contour lines, these lines are characteristic because they are placed perpendicular to the slope, for this reason, they are a method used to prevent erosion and retain water.
With this information in hand, we can see that option A is not correct because the use of plowing is related to soil loss and not to soil richness per se. Option B is not correct either because the use of insecticides is more related to the type of crop and surrounding vegetation cover. Option C in this case is the correct answer, it is used to reduce erosion and sediment pollution because helps retain soil. Finally, option D is not correct because this method is not related to livestock.

Pelvic spurs are vestigial structures. What is a vestigial structure?
Vestigial structures are an anatomical feature that no longer has a purpose in the current form of the organism, they do not have a apparent function like the pelvic spurs, human appendix and tail bone. It is most likely to be a residual part from a past ancestor.

How does the income level of a worker impact their ability to recover from environmental disasters?
Disasters are more likely to cause lives and property damage in poor areas, and they frequently lead to an increase in poverty afterward. Poorer communities frequently do not fully recover from disasters; instead, they experience a new normal and a lower status after a crisis.
Why are the effects of natural catastrophes worse among the poor?Due to their frequent relocation to high-risk locations, poor people are more frequently impacted by natural disasters. First, regions that provide economic prospects, public services or direct comforts, as well as better productivity and salaries, may be more desirable than others.
Various economic losses result from calamities. Infrastructure and capital assets, including buildings, industries, schools, roads, dams, and bridges, are destroyed. Owing to the loss of life, the exodus of trained labourers, and the disruption of education due to the destruction of educational infrastructure
Economic losses in the form of assets and local revenue will be a result of disasters.

Which of the following statements about unsaturated fats is true?
O Unsaturated fats contain the maximum number of hydrogens along the hydrocarbon tails.
O Unsaturated fats make up the majority of animal fats
O Unsaturated fats are less healthier for you than saturated fats.
O Unsaturated fats contain one or more double bonds along the hydrocarbon tails.
Unsaturated fats are a type of lipids mostly found in plant-based food, such as in seeds (one great example is oil). These lipids are characterized for having one or more double or triple bonds between the carbons of their structure and are healthier than saturated fats (found mostly in animal fats).
Therefore, the correct answer to this question is the last option.

The given reaction represents the process of photosynthesis.
Photosynthesis is the process by which plants synthesize their food. During photosynthesis, plants use carbon dioxide and water in the presence of sunlight to manufacture glucose (sugar) and liberate oxygen.
The reaction for photosynthesis can be given by the following equation:-
6CO2 + 6H2O + light ----> C6H12O6 + 6O2
Photosynthesis generally occurs in the leaves (which contain chloroplasts) of plants. The gaseous exchange takes place by means of pores called stomata, which are present in the leaves. Water is taken by the plants through the roots with the help of a vascular system. The chlorophyll pigment that is present in the chloroplasts within leaf cells is responsible for capturing sunlight.

The correct steps through which to identify the steps of the water cycle include:
Water moves from the hydrosphere to the atmosphere through evaporation.Water moves from the atmosphere to the lithosphere through precipitation.What is the Water cycle?The water cycle, also known as the hydrological cycle or hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth.
Water cycle stages
1. Evaporation
2. Sublimation
3. Condensation
4. Precipitation
5. Infiltration
6. Runoff
The water cycle has a huge effect o climate. For example, the greenhouse effect causes the temperature to rise. Without the cooling effect of evaporation from the water cycle, the Earth's temperature will rise dramatically.
The water cycle is also an integral part of other biogeochemical cycles. The water cycle affects all life processes on Earth.

Match the cell type (sex cell or somatic cell) with the examples provided.a. white blood cellb. spermc. egg (ova)d. hepatocyte (liver cell)e. epithelial (skin) cell
Sex cell is a gamete cell, used in sexual reproduction. which means that it will have half of the amount of chromosomes that other cells does, so it can merge with another sex cell and create a daughter cell (that is somatic) that has genetic material from both sex cells.
Somatic cell is every other cell, building our organs and our body, and it contains twice the amount of genetic material that's present in sex cells.
Therefore, we can match the examples as follows:
a. white blood cell - SOMATIC CELL
b. sperm - SEX CELL
c. egg (ova) - SEX CELL
d. hepatocyte (liver cell) - SOMATIC CELL
e. epithelial (skin) cell - SOMATIC CELL
