lipids are nonpolar moecules which means their ends are not charged. Because they are nonpolar and water is polar lipids are not soluble in water. That means the lipid molecules and water molecules do not bond or share electrons in any way. Hope this helps
If nondisjunction occurs during meiosis I, how many of the daughter cells will have an incorrect number of chromosomes after meiosis I and meiosis II are complete
If nondisjunction occurs during meiosis I, then four (4) daughter cells will have an incorrect number of chromosomes after meiosis.
What is non-disjunction?Non-disjunction refers to the faulty separation of chromosomes during cell division (either meiosis or mitosis).
Meiosis is a cell division that produces four daughter cells having half of the genetic material of the parental cell.
Non-disjunction in meiosis I is known to cause an imbalance in all daughter cells (i.e., in 4 daughter cells).

What important role does water play in the function that needs to be performed by the kidneys
Answer:
Water helps the kidneys remove waste from your blood through urine. Water also helps keep blood vessels open, which lets blood flow through easier, letting the blood remove its waste through the kidney more efficiently.
Explanation:
Answer:
It helps in Osmoregulation and removal of excess liquid from the body.
Explanation:
It regulates fluid balance by excreting excess amount of water as urine while retaining the necessary amount of water in the body that is essential for living.
Osmoregulation - the process of maintaining salt and water/osmotic balance across membranes within the body.
The fluids inside and surrounding cells are composed of water, electrolytes, and non-electrolytes.
What abiotic factors affect the rate of photosynthesis.
Answer:
The rate of photosynthesis in a plant can be determined by three external factors: temperature, light intensity, and available carbon dioxide concentration. In any given situation any one of these may become a limiting factor if they are below the optimal level (Alcott and Mindorff).
Determine whether each phrase mainly describes surface ocean currents or deep ocean currents. found near the top of the ocean caused by prevailing winds caused by differences in water density caused by differences in water temperature influenced by rotation of earth found closer to the ocean floor
Influenced by rotation of Earth
caused by prevailing winds
found near the top of the ocean
The phrases that describe deep Ocean currents are :
caused by differences in water
found closer to the ocean floor
caused by differences in water density
Surface ocean currents are found near the top of the ocean, and they are caused by prevailing winds. The wind creates a force on the surface of the ocean, which causes water to move in the direction of the wind.
What are these currents responsible for ?These currents are responsible for redistributing heat around the planet, making them an important factor in regulating climate.
Deep ocean currents, on the other hand, are caused by differences in water density and temperature. Cold, dense water sinks to the bottom of the ocean, creating a current that can move across the ocean floor.
This process is known as thermohaline circulation, and it helps to redistribute nutrients and oxygen throughout the ocean, making it an important factor in marine ecosystems.
The rotation of the earth also influences ocean currents. Due to the Coriolis effect, surface currents in the Northern Hemisphere tend to flow clockwise, while currents in the Southern Hemisphere tend to flow counterclockwise. This effect is caused by the rotation of the earth and the resulting centrifugal force.
Finally, currents that are found closer to the ocean floor are deep ocean currents. These currents are slower and less visible than surface currents but can have a significant impact on the ocean's circulation and the Earth's climate.

40 chromosomes would be found in the sperm produced by heat same squirrel.
What are Chromosomes?A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code. The very long, thin DNA fibres in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.
The highest possible level of DNA and protein organisation is seen in chromosomes. Chromosomes' primary job is to carry DNA and pass genetic material from one generation to the next. Cell division involves the critical function of chromosomes. They guard against tangles and damage to the DNA.
For above given example, if 20 chromosomes are present in skin cells, then the squirrel will have 40 chromosomes in the sperm cells.
Thus, 40 chromosomes would be found in the sperm produced by heat same squirrel.

A cement factory emits 900 kilograms of CO2 to produce 1,000 kilograms of cement. A fully grown tree removes six kilograms of CO2 per day from the air. One acre of land can support 200 mature trees.
A company builds a factory that will produce 100,000 kilograms of cement. To make the factory carbon neutral, the owners need to grow
trees over an area of land measuring
acres.
Answer: To make the factory carbon neutral, the owners need to grow 15000 trees over an area of land measuring 75 acres
Explanation:
From the information;
900 kg CO2 = 1000 kg Cement
1 tree = 6 kg CO2
1 acre = 200 trees
100000 kg Cement will require;
=(900 × 100000)/1000
= 90,000 kg of CO2
But 1 tree = 6 kg of CO2
Number of trees = 90,000/6
= 15,000 trees
But, 1 acre = 200 trees
Number of acres = 15,000/200
= 75 acres of land
Therefore;
To make the factory carbon neutral, the owners need to grow 15000 trees over an area of land measuring 75 acres

Describe what would happen to human *** cells (sperm and egg) if they were not formed by meiosis, but instead, formed by mitosis. How many chromosomes would each s** cell have? How would this affect fertilization and the newly formed cell
Answer:
Normally, meiosis causes each parent to give 23 chromosomes to a pregnancy. When a sperm fertilizes an egg, the union leads to a baby with 46 chromosomes.
But if meiosis doesn’t happen normally, a baby may have an extra chromosome (trisomy), or have a missing chromosome (monosomy). These problems can cause pregnancy loss.
Mitosisis the dividing of all other cells in the body. It’s how a baby in the womb grows. Mitosis causes the number of chromosomes to double to 92, and then split in half back to 46. This process repeats constantly in the cells as the baby grows. Mitosis continues throughout your lifetime. It replaces skin cells, blood cells, and other types of cells that are damaged or naturally die.
During pregnancy, an error in mitosis can occur. If the chromosomes don’t split into equal halves, the new cells can have an extra chromosome (47 total) or have a missing chromosome (45 total).
If gametes were produced instead by mitosis each gamete would be diploid not haploid. During fertilization of diploid gametes, the zygote would become 4n=92. With each new generation the number of chromosomes would double.

Approximately
% of the available energy is passed from organisms at one trophic level to organisms at the next trophic level.
Approximately 10% of the available energy is passed from organisms at one trophic level to organisms at the next trophic level. This is known as the 10% rule or the 10% energy transfer efficiency.
What is 10% rule?Energy flows through trophic levels in an ecosystem starting with producers (plants or algae) that convert sunlight into chemical energy through photosynthesis. When herbivores consume these producers, only a fraction of the energy stored in the plants is assimilated into their bodies, while the rest is lost as waste or used for metabolic processes like respiration. This assimilated energy becomes available to the next trophic level.
As energy moves up the food chain, similar inefficiencies occur at each level. Carnivores that consume herbivores receive only about 10% of the energy stored in their prey. This pattern continues as energy is transferred to higher-level predators.
The low energy transfer efficiency can be attributed to several factors. First, organisms expend energy for basic metabolic processes, such as respiration, movement, and growth, which reduces the energy available for transfer. Second, energy is lost as heat during these metabolic processes. Additionally, not all parts of an organism are consumed or digested by predators, resulting in energy losses through waste.
