How the respiratory system and circulatory system work together to supply oxygen and remove carbon dioxide from the cells?
The role of the respiratory system is to help in gaseous exchange and the role of the circulatory system is to supply oxygen and remove carbon dioxide from the tissue.
The respiratory system aids in the inhalation of oxygen and the exhalation of carbon dioxide. Additionally, the circulatory system is the system that aids in removing carbon dioxide from tissues by way of the lungs and supplying oxygen from the lungs to tissues. This method of oxygen supply and carbon dioxide waste removal is made possible by both of these processes.
The oxygen that is inhaled first travels to the lungs where it is exchanged with the blood that carries the waste (CO₂) from the tissue via the heart. From the heart, the oxygen in the oxygenated blood is delivered to the tissues. And the deoxygenated blood tissue carries the waste products from the tissue.

Compare and contrast the difference between the Upper mantle and the lower mantle.
The Upper Mantle is the uppermost portion of the Earth's mantle. It is composed of relatively cool rocks such as peridotite and basalt. The temperature is typically between 500 and 1000 degrees Celsius. It is mainly composed of minerals such as olivine, pyroxene, and garnet. It is relatively rigid and is the main source of orogeny.
The Lower Mantle is the portion of the Earth's mantle located below the upper mantle. It is composed of hot, dense rocks such as eclogite and dunite. The temperature is typically between 1000 and 2000 degrees Celsius. It is mainly composed of minerals such as bridgmanite, ferropericlase, and magnesiowüstite. It is ductile and is the main source of convection, which drives plate tectonics.

State a reason why the water lily lacks a waxy cuticle.
One reason why the water lily (Nymphaea spp.) lacks a waxy cuticle is because it is adapted to living in an aquatic environment. A waxy cuticle is a layer of cutin, a waterproof, protective coating found on the surface of plant leaves and stems. It helps to prevent water loss through evaporation and protect the plant from dehydration.
However, water lilies are adapted to living in an aquatic environment, where they are constantly surrounded by water. As a result, they do not need to worry about water loss through evaporation and do not have a waxy cuticle to prevent it. Instead, water lilies have evolved other mechanisms, such as thick, succulent leaves and stems, to help them absorb and store water.
Hope This Helps You!
The water lily lacks a waxy cuticle because it is generally present in the water, so it does not have the adaptation to save water, so it does not have the waxy cuticle, while these are the adaptations of the desert plants.
What is the significance of the water lily?The water lily is significant as it has an important role in aquatic ecosystems because it provides food for a wide variety of aquatic animals, such as insects and fish, while its roots can help stabilize shorelines, prevent erosion, and purify water by removing excess nutrients. Its seeds are of great interest to humans due to their high demands.

What is the motto of energy conservation?
Energy Conservation slogans make no unwise moves. Conserve fossil fuels. Burn fossil fuels right now to avoid becoming one tomorrow. Conserve fuel to save money.
By using fewer energy services, energy conservation aims to cut down on unnecessary energy use. This can be accomplished by modifying one's behavior to use less service or by using energy more efficiently (using less energy for continuous service) (for example, by driving less). Through effective energy use, which has a number of benefits, including a decrease in greenhouse gas emissions and a lower carbon footprint, as well as cost, water, and energy savings, energy conservation can be accomplished.
In the planning and construction of buildings, energy conservation is crucial. Since the 1970s, its prominence has grown. Recently, the significance of energy conservation has been highlighted by worries about the implications of climate change and global warming.

Each daughter cell will contain 46 chromosomes, if a cell has 46 chromosomes before mitosis.
Cell Division:
Cell division is important for a variety of biological processes, including gamete formation, body tissue repair, and healing of damaged tissues.
Mitosis means that the cells formed after division have the same number of chromosomes as the parent cell. The first stage of mitosis is prophase, in which chromosomal material condenses. The final stage is telophase, when the cell divides into her two cells. Both daughter cells after telophase have the same number of chromosomes.

Much like human skin color, violets' color is driven by proteins, especially in the case of violets, by enzymes. Enzymes (generally like proteins) need to function at a specific temperature. Outside this temperature, the enzyme cannot reach its correct form and eventually its function in vivo changes.
Regarding the above question, the plants were in a greenhouse that changed the natural temperature of the environment, so the violets' color change was due to the enzymes involved in flower color shrinking appropriately at low temperatures and the greenhouse being warm in the middle.

Which of the following best explains the differences in flower color of the African violets in the greenhouse?
A Warmer temperatures result in genotypic alterations, which result in flower color differences.
B The plants along the walls of the greenhouse are homozygous recessive and therefore have white flowers.
C An enzyme responsible for flower color does not fold correctly in cooler temperatures, and the greenhouse is warmest in the center.
D More light is available along the walls of the greenhouse, so the flowers need less pigment to absorb sunlight for photosynthesis.
What is the probability of the offspring being purple and white flowers answer in percentage?
These would have phenotypes (PP and Pp) of 75% purple and 25% white (pp). The colour of the pea plant's blooms was one of the important characteristics Mendel examined.
When two heterozygous tall pea plants with purple flowers are crossed, it is possible that one of the offspring may be short with white flowers. This is similar to the monohybrid cross and depends on the individual probabilities of the traits. This means that there is a 1/4 chance that one of their progeny will be short and a 1/4 chance that one will have white flowers (in case of monohybrid cross). The genotypes of the offspring born from the union of a heterozygous purple flower (Rr) and a recessive white flower (rr) are (Rr), (Rr), (rr), and (rr). Consequently, half of the progeny have purple flowers (Rr), while half have white blooms (rr).

eats mainly apple snails, have to do to
adapt to its environment? (Please
explain)
If the apple snail population were to decrease, the limpkin, a secondary consumer that eats mainly apple snails, would have to find an alternative food source in order to adapt to its environment. This could involve finding other types of snails or mollusks to eat, or potentially switching to a diet that includes other types of prey. The limpkin may also need to range over a larger area in order to locate sufficient food, or it may need to change its foraging behavior in order to more effectively locate and capture its preferred prey. Ultimately, the limpkin's ability to adapt to a decline in the apple snail population will depend on the availability of other suitable food sources and the flexibility of its foraging behavior.

The theory of spontaneous generation stated that life happens to originate from non-living matter. A lot of scientists were in support and also against the theory. Louis Pasteur conducted an experiment using the swan-necked flask to disprove this theory.
In his experiment, he took a swan-necked flask which was shaped like an "S" and in that flask he put a nutrition rich broth. After this, he boiled the broth in order to kill any microorganisms which were already present in the broth. The broth was exposed to the air left undisturbed.
