The function of a flower is to carry out sexual reduplication in shops through the conformation of manly and womanish gametes.

Flowers insure that the gametes fertilise to form seeds that further help in reproducing shops. Their primary purpose is reduplication. During the reproductive process, flowers make use of their various petals to attract pollinators similar as insects and creatures. These brutes are also allured by the quencher that flowers produce in their nectaries, glands that are frequently set up at the base of their petals. By producing quencher, flowers are suitable to give food for the insects that help to pollinate the shops. After a flower is pollinated, its fertilized ovule develops into a seed that can produce a new factory; and the ovary that formed the ovule becomes a fruit. The process of plant reduplication, also, also generates food for people and creatures to eat.

The enzyme catalase is responsible for breaking down hydrogen peroxide into water and oxygen. Like many enzymes, the activity of catalase is sensitive to changes in temperature and pH leading to variations in enzyme activity.

The optimal temperature for catalase activity in humans is around 37°C, which is the average body temperature. At this temperature, the enzyme works efficiently and can break down hydrogen peroxide quickly. If the temperature is too low, the reaction rate will be slower, and if it's too high, the enzyme can be damaged, resulting in a decrease in activity.

The optimal pH for catalase activity in humans is between pH 7 and 8.  At low pH levels (acidic conditions), the enzyme can become denatured, which results in a decrease in activity. At high pH levels (alkaline conditions), the enzyme can become inactive, which also results in a decrease in activity.

Metamorphic, Sedimentary, and Igneous

Explanation:

Igneous rocks can melt and solidify again, forming another igneous rock. Igneous rocks can also change into sedimentary rocks or metamorphic rocks. Hope this helps!!

Igneous rocks can form intrusive, extrusive, and metamorphic rock.

Intrusive rocks: These form when magma cools and solidifies beneath the Earth's surface. The slow cooling allows for the growth of large mineral crystals. Examples of intrusive igneous rocks include granite and diorite.

Extrusive rocks: These form when lava or volcanic ash cools and solidifies on the Earth's surface or in shallow underground chambers. The rapid cooling doesn't allow much time for crystal growth, resulting in fine-grained textures. Examples of extrusive igneous rocks include basalt and obsidian.

Metamorphic rocks: Igneous rocks, both intrusive and extrusive, can undergo changes in texture and mineral composition due to high temperature and pressure over time. These transformed rocks are called metamorphic rocks. Examples include gneiss and marble.

Answer: Chloroplast

Explanation:

Plants and some algae have chloroplasts responsible for photosynthesis. Plants undergo photosynthesis to transform light energy into chemical energy. This energy is stored in the form of sugar to support their growth and provide energy. Chloroplasts have a double membrane, with the thylakoid membrane located within the inner membrane.

Photosynthesis occurs within the thylakoid membrane, which is folded into sacs called thylakoids. Chlorophyll, a green pigment, is present in the thylakoids and it absorbs light energy to split water molecules into hydrogen and oxygen. The oxygen is released into the atmosphere while the hydrogen is used to create ATP, a molecule that stores energy. ATP and hydrogen are then utilized to make sugar, the final product of photosynthesis.

Answer:

if humidity increases, the space in air will be less and so the transpiration rate will decrease and vice versa, as they are inversely proportional.

Answer:

We do not let it happen we always end stopping the process.

Explanation:

The legs of animals often have a wider temperature range compared to their core body temperature due to adaptations such as counter-current heat exchange, regulation of blood flow, and differences in insulation.

Animals, especially those in colder environments, often have adaptations that allow their legs to have a wider temperature range compared to their core body temperature. .

Counter-current heat exchange: Many animals have blood vessels in their legs arranged in a counter-current heat exchange system, where warm arterial blood flowing to the legs passes close to colder venous blood returning from the extremities.

Peripheral vasoconstriction and dilation: Animals can regulate the blood flow to their extremities by constricting or dilating blood vessels. In colder conditions, blood vessels in the legs can constrict, reducing blood flow and heat loss to the environment.

Insulation: Some animals have adaptations such as fur, feathers, or blubber in their core body region to provide additional insulation and retain heat.

In summary, These adaptations allow animals to maintain a stable core body temperature while tolerating wider temperature variations in their extremities.

Answer: Reason of selective pressure

Explanation:

Answer:

     The mass (increasingly bigger size) of a tree comes from the soil. Which makes sense, right? After all, we are taught that plants need soil (enhanced “dirt”) to grow. According to Michigan State University Extension, problems typically arise when asked to explain why there isn’t a big hole around a tree. If the tree is using soil, then there must be less soil around it. But studies show virtually no difference in the amount of soil in a pot when a seed is planted from the amount of soil in the same pot when the plant from that seed is harvested. So where does the mass come from?

    The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun’s energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water. Yes, the carbon from carbon dioxide in the air we breathe out ends up in “food” molecules (called glucose) each of which contains 6 carbon atoms (and 12 hydrogen atoms and 6 oxygen atoms).

The temperature and pressure conditions of surface air at the equator are characterized by high temperatures and low atmospheric pressure.

Due to the direct exposure to the sun's intense radiation, the equator receives a significant amount of solar energy. As a result, the surface air at the equator is generally warm to hot. The equatorial region experiences high temperatures throughout the year, with average temperatures often exceeding 30 degrees Celsius (86 degrees Fahrenheit).

In terms of atmospheric pressure, the equator is associated with low pressure. The intense heating of the air causes it to rise, creating an area of low pressure at the surface. This low-pressure zone is known as the Intertropical Convergence Zone (ITCZ). The rising warm air leads to the formation of convective clouds and frequent precipitation in the equatorial regions.

These temperature and pressure conditions at the equator play a significant role in driving atmospheric circulation patterns, including the formation of Hadley cells and the redistribution of heat and moisture across the globe.
