Which is a primary way that enzymes affect these reactions? *
Answer: chemical reactions
Explanation: The function of an enzyme is to speed up chemical reactions. They do this by lowering the activation energy, which is the minimum energy that must be available for a chemical reaction to occur. If the energy required is lowered, the reaction can go faster.

How does a fire help grasslands?
Choose all that apply
Answer:
In most grassland ecosystems, fire is the primary mode of decomposition
Explanation:
Grasslands burn more readily than forest and shrub ecosystems, with the fire moving through the stems and leaves of herbaceous plants and only lightly heating the underlying soil, even in cases of high intensity. In most grassland ecosystems, fire is the primary mode of decomposition, making it crucial in the recycling of nutrients. In some grassland systems, fire only became the primary mode of decomposition after the disappearance of large migratory herds of browsing or grazing megafauna driven by predator pressure. In the absence of functional communities of large migratory herds of herbivorous megafauna and attendant predators, overuse of fire to maintain grassland ecosystems may lead to excessive oxidation, loss of carbon, and desertification in susceptible climates. Some grassland ecosystems respond poorly to fire.
A fire helps grasslands through the following:
Keeps trees from overtaking the grasses.Preserve biodiversity.What is Fire?This is the visible aspect of combustion of fuel and other materials to produce heat and flame.
controlled burning increases biodiversity by increasing spatial and temporal variation and helps prevent trees from overtaking grasses.

the formula for speed is speed=distance/time, this is the formula that should be used here. 50,000/25, which equals 2,000
¿Qué tipo de proceso metabólico se realiza cuando los lípidos y los fosfolípidos y triglicéridos se forman a ser moléculas sencillas dentro de la célula?
Answer:
catabólico
Explanation:
Los procesos metabólicos pueden ser:
Anabólicos: donde se forman moléculas más complejas a partir de moléculas simples. Esta formación de moléculas o estructuras más complejas consume energía. Catabólicos: donde se degradan o descomponen moléculas grandes o más complejas en otras más simples. Este proceso libera energía, que es utilizada en otros procesos y reacciones.En base a esto, la formación de moléculas sencillas a partir de moléculas grandes como los lípidos, fosfolípidos y triglicéridos es es proceso catabólico. En esta descomposición se produce energía para ser usada en otras reacciones.

Explanation:
Which of the following is not a possible benefit of biodiversity?
a
A higher number of species in a food web creates a more stable ecosystem.
b
A greater variety of predators indicates that fewer prey survive within the ecosystem.
c
A greater number of plant species provide more available food for primary consumers.
d
A variety of habitats within an ecosystem supports a greater number of species.
Answer:
b
Explanation:
because the more predators less prey and less organisms
It seems unlikely that biodiversity will result in fewer prey animals surviving in the environment due to the diversity of predators. So, the correct option is B.
What is Biodiversity?The variety of all living things and how they interact with one another and the environment are referred to as biodiversity. Along with species diversity both inside and between them, this also refers to ecosystem and landscape diversity.
Because it helps ecosystems function and provide services like pollination, nutrient cycling, or climate management, biodiversity is significant. For human communities, it also has significant cultural, social, and economic importance.
The range and variety of life on Earth is referred to as biodiversity or biological diversity. A measure of variation at the levels of genes, species, and ecosystems is called biodiversity.
Therefore, the correct option is B.

1- how can prokaryotes be used by humans/professionals?
2- how can eukaryotes be used by humans/professionals?
3- how can digestive system be used by professionals?
Answer: 1 Fermentation processes, such as brewing, baking, and cheese and butter manufacturing. Chemical manufacturing, such as the production of ethanol, acetone, organic acids, enzymes, and perfumes. Pharmaceuticals, such as the manufacture of antibiotics, vaccines, and steroids. Energy, in the form of biogas (methane)
2 Despite the fact that we have gobs of prokaryotic cells living inside and on us, humans are still categorically eukaryotic organisms. This means that all human cells—including those found in the brain, the heart, the muscles, and so on—are also eukaryotic.
3 Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.

Explain why ecologists think the focus of conservation efforts should be ecosystems, not individual species?
It depends on the species and its primary threats, there is no universal solution. Many South East Asian species are primarily threatened by poaching ("Empty forest syndrome"), whereas many "reptiles" and amphibians from Madagascar can apparently cope with fairly high levels of collection (e.g. Golden Mantella [Mantella aurantiaca]), while the loss of their often small habitat is the primary threat.
How might a plant cope with the fact that the Calvin cycle uses more ATP than NADPH, yet produces roughly the same amount of both energy intermediates in photosystems I and II? Group of answer choices Electron flow rate can be increased, increasing both ATP and NADPH production. Plants often increase the amount of NADP reductase, thereby increasing NADPH production to match ATP output. Increase the electrochemical gradient for H+ across the thylakoid membrane, producing more ATP but not NADPH. Photosynthesis can revert from a noncyclic to cyclic electron flow, producing more ATP than NADPH. More pigment can be rapidly created for greater photosynthetic capacity, producing equal amounts of ATP and NADPH.
Answer:
Photosynthesis can revert from a noncyclic to cyclic electron flow, producing more ATP than NADPH.
Explanation:
A Calvin Cycle is defined as a process by which various plants and algae takes carbon dioxide from the air and turns it into sugar, the food which the food autotrophs needs to grow. The Calvin cycle is required for every living being on earth to survive.
Both the ATP and the NADPH are required by the Calvin cycle. It occurs in the chloroplast stroma of the plants. Calvin cycle uses more amount of ATP than the NADPH and produces roughly same amount of both the energies. Photosynthesis may revert from the noncyclic to the cyclic electron flow and it produces more ATP than NADPH.
