what is the ultimate source of electrons for photosynthesis in plants?
Answer: Water
Explanation:
What is the ultimate source of electrons for photosynthesis?
In photosynthesis, water is the source of electrons and their final destination is NADP+ to make NADPH
Photosynthesis is a plant process to make food and energy. It includes various steps to release energy. The water molecule is the ultimate electron donor in the process.
What is photosynthesis?Photosynthesis is said to be the process that converts solar energy into the chemicals that are used as the energy source in cellular respiration activities. Here, sunlight, carbon dioxide, and water act as reactants.
The carbon dioxide and water undergo splitting by the membrane pigments and then the electron produced from water is carried with enzymes to make NADP⁺. This is further used to make NADPH. As result oxygen along with the sugar molecules are produced and are rich in ATP.
Therefore, water is the foremost source of electrons for photosynthesis in plants.

what de-polymerizes microtubules to separate sister chromatids during anaphase?
Mitotic spindles depolymerize microtubules to separate sister chromatids during anaphase.
What are microtubules?Microtubules are present inside the cell. They are present in bundles, and they are together with a group of 9 to 11 microtubules. They are rigid and hollow from the inside. They are part of the exoskeleton.
Regarding how chromosomes travel during anaphase A, there are two primary theories. One is that the chromosomes are pulled along the kinetochore microtubules by motor proteins at the kinetochores using the energy from ATP hydrolysis, which causes the microtubules to depolymerize.
Therefore, the microtubules are separated or depolymerized by spindle fibers, to separate the sister chromatids into lines.

what will happen to a population of organisms that are in an oxygen rich environment. (Double click the story board to draw on it)
Answer
I'll assume this means adding additional oxygen to the atmosphere.
Paper airplanes now fly farther. With all that extra air, the air pressure near the surface increases significantly. Gliders, parachutists, birds and paper-plane hobbyists enjoy greatly improved performance.
Everyone gets better gas mileage. Oxygen-enriched air improves engine performance by producing hotter reactions and reducing the proportion of nitrogen, which reduces heat transfer (Page on Energy.gov)
Higher elevation Biomes become inhabited by more vertebrates. Areas such as the high Himalayas or high Andes are no longer off-limits to animals without special adaptations to increase their levels of hemoglobin.
Insects of unusual size. Many insects rely on gaseous diffusion to for respiration, therefore the maximum body size depends on the proportion of oxygen gas in the atmosphere. Most bugs get bigger, some smaller (see Atmospheric oxygen level and the evolution of insect body size)
Everyone feels more alert, active, and happier. All that fresh oxygen improve our cognition, alertness, and physical performance. As a result, most athletic records would likely be broken by oxygen-enriched athletes.
We get sick less often. Neutrophils, soldiers of the immune system, destroy bacteria by using NADP oxidase to pump ions into, and disrupt, intruding cell's membranes causing rupture. More oxygen, more oxidase. (Page on Nih.gov)
We die younger. Free radicals (i.e. O2-) are thought to exacerbate the aging process through Oxidative stress, which interferes in numerous cellular processes: protein production, DNA replication, intercellular communication, and are also thought to contribute to MS, Alzheimers, Parkinsons, and a host of other ailments.

1. A rapidly increasing human population is the primary driver behind what
LEADING cause of the loss of biodiversity? (SEV5.a) *
O a. Extinction
O b. Habitat Loss
O c. Pollution
O d. Overexploitation
Answer:
your answer is B. Habitat Loss
Explanation:
What is the #1 cause for the loss of biodiversity?
Habitat destruction
Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.
Habitat loss and overexploitation, driven by our rapid population growth and unsustainable consumption patterns, are the primary causes of biodiversity loss which is now happening up to ten thousand times faster than for millions of years before.

What do invasive species do when in a new area?
Breed with existing species
Get in balance with the existing food chains
"Take over" the area and become more successful than the native species
Die because they cannot survive
Answer:
"Take over" the area and become more successful than the native species
Explanation:
Invasive species are species that are introduced to a habitat they are not native to. They are environmentally problematic becasue they disrupt native ecosystems in which they are able to thrive. They do not usually breed with existing species, they can disrupt existing food chains, and they wouldn't be invasive if they died out.
how can several classification categories be used on the same object????????
Answer: Several classification categories can be used on the same object by characteristics that have been given.
Explanation:
Kingdom:
The highest category into which organisms are classified.
Phylum:
A category used in the classification that consists of one or several similar or
closely related classes. You may also use DIVISION.
Class:
One or several similar or closely related orders. Similar classes are grouped
into PHYLUM.
Order:
One or several similar or closely related families. Similar orders form a
CLASS.
Family:
One or several similar or closely related genera. Similar families are grouped
into an ORDER. The names are usually determined from a type genus (Cactus,
Equus) that is characteristic of the whole family.
Genus (pl. genera):
A number of similar or closely related species. The common name of an organism
is sometimes identical to the genus, e.g. Lilium = lily. Similar genera are
grouped into a FAMILY.
Species:
A group of similar individuals that can breed and produce fertile offspring.
Similar and related species are grouped into a GENUS. Within certain groups,
species may not mate and will under different selection pressures develop
different characteristics form the main population. This is called a
subspecies.
Hope this helps!!!
By characteristics, multiple classification categories can be applied to the same object.
How the classification is done ?
The specificity of the categories within a taxonomic classification increases.Domain, the point of origin for all species, is the most general category in taxonomic classification; One of these domains is shared by all species: Eukarya, bacteria, and archaeaKingdoms are the second taxonomic classification category within each of the three domains, followed by phylum, class, order, family, genus, and species categories.Because they are more closely related, organisms become more similar at each classification category.As inaccuracies in classifications are discovered and rectified, changes to the taxonomic classification of many species must be made as scientific technology advances.A hierarchical model is used in the taxonomic classification system, which is also known as the Linnaean system after its creator, Swedish botanist, zoologist, and physician Carl Linnaeus.The groups get more specific as they move away from the point of origin, until one branch becomes a single species.For instance, scientists divide organisms into three large domains following the common beginning of all life: Eukarya, bacteria, and archaea.A kingdom is a second category that exists within each domain.The following categories of increasing specificity follow kingdoms: family, genus, class, order, phylum, and species.Plants and animals are two types of living things.Plants can be further divided into flowering and non-flowering varieties or grouped according to other characteristics.Insects, reptiles, fishes, mammals, and others are subcategories of animals.To know more about classification check this :

Explain how kinetic energy affects each object as it changes its state of matter:
A) Water boiling:
B) Popsicle freezing:
C) Water condensing on the side of a water bottle:
Answer:
Explain how kinetic energy affects each object as it changes its state of matter:
A) Water boiling:
B) Popsicle freezing:
C) Water condensing on the side of a water bottle:
Explanation:
A) A water boiling will result in evaporation, therefore the particles will move extensively faster than liquid due to it being vapor.
B) A popsicle freezing is originally a solid so it'll have the least amount of kinetic energy as the particles remain fairly slow.
C) Due to the fact that water is condensing, while turning into a liquid. The water condensing on the side of the water bottle would produce a lower kinetic energy level due to the fact that it's becoming a liquid. Though liquids have higher kinetic energy than solids, as gases have a higher kinetic energy compared to liquids.
Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.
What is Kinetic energy?A popsicle is initially a solid, it will have the least kinetic energy because the particles are still moving slowly. Because water is condensing as it transforms into a liquid.
Because it is turning into a liquid, the water that is condensing on the water bottle's side would have less kinetic energy.
Gases have a higher kinetic energy than liquids, despite the fact that liquids have a higher kinetic energy than solids.
Therefore, Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.
