Answer:

What is photosynthesis?

Photosynthesis is a chemical process through which plants produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy.

Process of photosynthesis

1. Chlorophyll absorbs the sun's energy.

2. It is this energy that is used to split water molecules into hydrogen and oxygen.

3. Xylem which is found in the stem, allows water to go up the roots and into the plants.

4. Carbon dioxide enters the plant through the stomata, which are pores that allow for the exchange of gases

5. Carbon dioxide and water reach the chloroplast

6. Water and carbon dioxide are used to form glucose and oxygen for plants.

7. Glucose is converted into a starch and stored for food

How does a plant release oxygen from photosynthesis?

They release CO2 (just like us, when we breathe). But, when plants are photosynthesizing, they release more O2 during photosynthesis than they will consume in respiration. They release the oxygen through the same pores (stomata) that allow the CO2 to enter their leaf cells.

Eliminating invasive plants and replacing them with native plants is an essential aspect of urban management. Invasive plants can take over an ecosystem, causing harm to native species and disrupting ecological balance.

In contrast, native plants are well-suited to local environmental conditions and can support local wildlife. Urban management involves the planning, development, and maintenance of urban areas, including parks, gardens, and other green spaces.

The removal of invasive plants and the planting of native plants is an important part of maintaining these areas and preserving their ecological health. Replacing invasive plants with native plants can also help to mitigate the effects of climate change.

Based on this evidence of Lactose tolerance is a phenotypic trait positive selection in human populations statement is correct is Lactose tolerance is an example of gene-culture coevolution.

It should read, "Lactose tolerance is an example of gene-culture coevolution." This is so because cultures that consumed dairy products had a selection advantage if they could digest lactose into adulthood, a feature that emerged as a result of the cultural practise of dairy farming.

A character state, phenotypic characteristic, or simply trait is a unique variation of a phenotypic trait that can be inherited or acquired by environmental factors, but it usually results from a mix of the two. For instance, an organism's eye colour is a trait, but eye colours like blue, brown, and hazel are characteristics. Generally speaking, the word "trait" refers to the phenotypic manifestation of various allele combinations in various individual organisms within a single population, such as the well-known purple vs. white blossom colours in Gregor Mendel's pea plants.

Answer:

ringworms are fungis

they transmit viruses and bacteria to humans

Answer:

C. They are biotic

Explanation:

Fungi are not plants. Living things are organized for study into large, basic groups called kingdoms. Fungi were listed in the Plant Kingdom for many years. Then scientists learned that fungi show a closer relation to animals, but are unique and separate life forms.

I am not sure about the second option but I would say that it is also A. Ringworm is fungi

Ringworm is a common infection of the skin and nails that are caused by fungus. The infection is called “ringworm” because it can cause an itchy, red, circular rash. Ringworm is also called “tinea” or “dermatophytosis.” The different types of ringworm are usually named for the location of the infection on the body.

What I can conclude about ringworm is that a type of fungus causes them but I am not sure that they are classified as one too.

The effect of treating a flowering plant with plant hormones influences all aspects of plant growth, reproduction, seed germination, length of hypocotyl, ripening of fruits, etc.

Plant hormones may be defined as those chemicals which are synthesized by the plants in order to regulate their entire mechanisms of growth, development, reproductive processes, longevity, and even death. Such chemical compounds are known as phytohormones.

Auxin, cytokinin, and Gibberellin promote growth by activating cell division directly or indirectly. Gibberellin causes stem length formation that regulates the overall height of the plants. This hormone is also involved in seed germination. Ethylene is the fruit ripening hormone.

Answer:

IV flow rate (ggt/min) required for the patient = 21 ggt/min to the nearest whole number

Explanation:

To calculate IV flow rate or the drops per minute, the drop factor is needed.

The drop factor is the number of drops in one mL of solution, and is printed on the IV tubing package.

The formula for calculating the IV flow rate (drip rate) is given as;

IV flow rate (ggt/min) = {total volume (mL) / time (min)} * drop factor (gtts/mL)

From the given values in the question, drop factor = 10 ggt/mL; time in minutes = 8 hours * 60 minutes/hour = 480 minutes; volume of IV fliud = 1 litre = 1000 mL

Therefore, IV flow rate (ggt/min) = (1000/480) * 10 = 20.33

IV flow rate (ggt/min) required for the patient = 21 ggt/min to the nearest whole number

A bacterium that only possesses the ability to fermentation obtains energy by glycolysis only.

Glycolysis is the first stage of fermentation; however, it does not involve the final two phases of aerobic cellular respiration (the Krebs cycle and oxidative phosphorylation). Two NAD+ electron carriers are converted during glycolysis into two NADH molecules and two net ATPs. For glycolysis to proceed and for cells to continue generating 2 ATPs, the NADH must be oxidized again. Because oxidative phosphorylation cannot occur during fermentation due to a lack of oxygen, cells are only able to produce 2 ATP at a time. Alcoholic and lactic acid fermentation are the two forms of fermentation. We use both forms of fermentation using other organisms even though our cells can only execute lactic acid fermentation.

Homeostasis control in living things is exerted over all of the following except response to stimuli. The correct answer is C.

Homeostasis is the ability of a living organism or cell to maintain a stable internal environment despite changes in external conditions. It involves the regulation of various physiological parameters, such as temperature, pH, fluid balance, moisture level, acidity level, and glucose levels, through feedback mechanisms that help to maintain a balanced and stable state.

This allows the organism or cell to function optimally and respond effectively to environmental challenges or changes. Homeostasis is essential for survival and is maintained by complex physiological and biochemical processes that work in harmony to keep the internal environment within a narrow range of acceptable levels.

However, the response to stimuli, such as sensory input from the environment, is not directly controlled by homeostatic mechanisms but by other physiological processes such as reflexes, sensory perception, and decision making in the brain.

Two molecules are formed from the cleavage of glucose during the first step of glycolysis, each containing three carbons.

For the duration of the first step of glycolysis, glucose is transformed into two molecules of glyceraldehyde-3-phosphate (G3P) through a process referred to as cleavage. This step happens within the cytoplasm of the cellular and is catalyzed by an enzyme known as aldolase.

The cleavage of glucose includes breaking the six-carbon molecule into two 3-carbon molecules. In this step, a phosphate organization is brought to the molecule, which is then split into two 3-carbon molecules known as G3P.

Each molecule of G3P contains a phosphate institution, which lets it be converted into pyruvate in later steps of glycolysis. As for the second part of the question, every molecule of G3P includes 3 carbons.

Therefore, the ensuing molecules from the cleavage of glucose additionally include three carbons each. The carbons are numbered for every molecule beginning with the carbon closest to the phosphate institution.

The molecule can then be represented as glyceraldehyde-3-phosphate, in which the three indicate the carbon wide variety.

Explanation:

The symbiotic relationship is the relationship in which two distinct species are associated with each other. In the symbiotic relation the species may get harm or benefit of association. Parasitism can be defined as the symbiotic relationship in which one species get harmed and other one receives the benefit. For example, malarial parasite plasmodium derives the nourishment from the host body (human). Predator-prey relationship is also harmful as the predator kills the prey to obtain it as food. Competition is harmful in the sense two or more organisms of the same or different species compete for the same resource, the most dominant receives the resource the inferior organism is either killed or harmed in the fight for resources.
