eukaryotes are organisms that contain more than one cell with membrane-bound organelles and a nucleus.
Eukaryotes are organisms with cells that contain a membrane-bound nucleus and organelles. They can be unicellular or multicellular and are distinct from prokaryotes, which lack a nucleus and membrane-bound organelles. Eukaryotic cells are typically larger and more complex than prokaryotic cells.
Organisms that contain more than one cell with membrane-bound organelles and a nucleus are known as eukaryotes. These organisms can be made up of a single cell or can be multicellular. They are characterized by having a nucleus that contains the organism's genetic material and is surrounded by a complex nuclear membrane. Additionally, eukaryotic cells contain several other membrane-bound organelles, such as mitochondria, endoplasmic reticulum, and Golgi apparatus, which perform specific functions necessary for the cell's survival and operation.
Eukaryotic organisms include a vast array of life forms including protozoa, fungi, plants, and animals. A significant difference between eukaryotes and prokaryotic cells, such as bacteria, is the presence of a nucleus and other membrane-bound organelles in eukaryotes, which are not found in prokaryotes. Eukaryotic cells are typically larger than prokaryotic cells and are the building blocks of complex organisms.

Which statements describe Newton and the law of universal gravitation? Check all that apply
Newton's Universal Law of Gravitation states that each particle in the universe attracts every other particle with a force that is directly proportional to their masses and inversely proportional to the distance squared between them. Newton's formulation is essential for understanding gravitational forces in classical physics and is foundational for calculating planetary orbits and terrestrial gravity.
Understanding Newton's Law of Universal Gravitation
Sir Isaac Newton formulated the Universal Law of Gravitation, which revolutionized our understanding of how objects in the universe interact through gravity. This law states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses. This gravitational force is also inversely proportional to the square of the distance between the particles.
The formula for Newton's universal law of gravitation can be expressed as F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two particles, and r is the distance between them. This law has been key to understanding celestial mechanics and is a cornerstone of classical physics. It is also the fundamental principle understanding the orbits of planets and the behavior of objects under the influence of gravity on Earth.
However, it's important to recognize that Newton's law was later supplemented by Einstein's theory of general relativity, which gives an even more accurate description of gravitational phenomena, especially near very massive objects or at very high velocities. Nonetheless, Newton's law of universal gravitation remains a crucial tool for common gravitational calculations in everyday situations where general relativity has negligible impact.

As the algae and other plants begin to die, they cause the bacterial population to explode. The bacteria exhaust the supply of dissolved oxygen needed by animals living in the water. What will happen to the minnow population?
Answer:
The population of these fish will decrease, because they will end up dying from lack of oxygen.
Explanation:
The low concentration of oxygen in the water is very harmful to fish.
Fish, when exposed to a low concentration of oxygen in the water, even for a short period of time, do not face so many problems as long as other water quality parameters such as pH, ammonia, and nitrite are at acceptable levels. However, a permanent value below 60% saturation is intended to cause problems in fish health. Most survive a few days with a saturation of 40%, but if the oxygen concentration drops quickly, the fish will begin to feel the effects of the lack of oxygen and will eventually die.

In a deck of cards, with 52 cards and 4 suits, what is the probability of getting an ace?
There are four aces in a deck of 52 cards, one of each suit. Out of 52, you have 4. So... 4/52. We reduce this by dividing the numerator and denomerator by 4 to get 1/13.
Answer:
1/13
Explanation:
Match the following terms and definitions.
1. a waxy substance covering most surface areas of plants; helps to retain water gametophyte
2. plant that produces gametes vascular plant
3. plant lacking conductive tissues within it, using osmosis or diffusion to obtain nutrients; also called bryophytes cuticle
4. a process in green plants that involves the use of carbon dioxide and water in the production of glucose and oxygen using the Sun's energy nonvascular plant
5. transfer of pollen from male to female cones in gymnosperms, or from the anther to the stigma in flowering plants pollination
6. root-like projections of nonvascular plants which help it stay anchored to the ground rhizoids
7. plant that produces spores by meiosis sporophyte
8. plant that has true conductive tissues within it; usually has true roots, stems, and leaves photosynthesis
Answer:
The correct match would be:
1. Cuticle: It is a wax like substance made up of lipids and integrated hydrocarbon polymer usually synthesized by epidermal cells. It prevents or reduces the excessive loss of water.
2. Gametophyte: It is a sexual phase of plants in which they produce haploid gametes by the process of meiosis.
3. Nonvascular plant: As the name suggests, they are the plants which lack vascular system. They are also known as bryophytes and are divided into three types namely mosses, liverworts and hornworts.
4. Photosynthesis: It is the process by which producers or green plants make their food from carbon dioxide and water with the help of sunlight and chlorophyll.
5. Pollination: It is the process by which pollen grains are transferred from anther to stigma in flowering plants. Air, water, insects etc help in this process.
6. Rhizoids: It is a filamentous outgrowth found in some lower plants which serves the purpose of anchoring and conduction of water.
7. Sporophytes: These are the diploid plants which produces haploid spores by the process of meiosis.
8. Vascular plants: These are the higher plants which have fully developed vascular system i.e. they contain fully developed and functional xylem and phloem.
The gametophytes are the is the sexual phase present in the life of algae and plants. The haploid gametes are produced from the parents.
The vascular plants are those which have specified tissues for the transport of the minerals and water.
The bryophytes do not have cuticle present and hence, they absorb the nutrients through their dermis.
The non vascular plants are those which do not have specialized tissue for the transport of water and minerals.
Pollination can be defined as the transfer of the pollen grain from the anther to the stigma of the same or different flower of the same species.
Rhizoids can be defined as the filamentous growth present in lower plants on their underside.
Sporophyte is the reproductive stage in algae and plants when the haploid male and female gametes fuse together to form zygote.
Photosynthesis is the process by which the plants develop their food using the sunlight, water and carbondioxide.
Hence, the given terms and definitions can be matched as follows:
All annelids and arthropods have a body plan. Unlike annelids, arthropods also have . The circulatory system of annelids is , while the circulatory system of arthropods is .
All annelids and arthropods have a SEGMENTED body plan. Unlike annelids, anthropoids have also have an EXOSKELETON. The circulatory system of annelids is CLOSED AND INCLUDES BLOOD VESSELS, while the circulatory system of arthropods is OPEN AND USES HEMOCYANIN.

List and explain three of the factors that determine how quickly rock is weathered
So here are some factors:
- Height: the lower to the ground, the more particles wind carries, which is where we'll notice weathering the most.
- Type: there are different types of rocks, each of them with a different hardness, and the harder a rock, the more difficult it'll be to weather.
- Location climate: a rock in a place with weak winds and not that much rain will take longer to weather.

Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind, and ice.
The factors that determines how quickly are:
CLIMATE: The amount of water in the air and the temperature of an area are both part of an area's climate. Moisture speeds up chemical weathering. Weathering occurs fastest in hot, wet climates. It occurs very slowly in hot and dry climates.Rainfall and temperature can affect the rate in which rocks weather. Minerals in a rock buried in soil will therefore break down more rapidly than minerals in a rock that is exposed to air.Which of the following could be considered both a renewable resource and a no renewable resource A)iron ore B) sea water C) solar energy D) wheat crop

A Mercator projection map shows?
Mercator projection, type of map projection introduced in 1569 by Gerardus Mercator. It is often described as a cylindrical projection, but it must be derived mathematically. The meridians are equally spaced parallel vertical lines, and the parallels of latitude are parallel horizontal straight lines that are spaced farther and farther apart as their distance from the Equator increases. This projection is widely used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course. It is less practical for world maps, however, because the scale is distorted; areas farther away from the Equator appear disproportionately large. On a Mercator projection, for example, the landmass of Greenland appears to be greater than that of the continent of South America; in actual area, Greenland is smaller than the Arabian Peninsula.
Answer:
Navigation or locations with constant true bearing
Explanation:
Mercator maps are maps that are used for projecting the world on a piece of paper that has certain number of parallel horizontal and vertical parallel lines. Therefore, exact location of any point can be derived from such maps in terms of constant geographical bearings. The parallel lines are called latitude and the vertical lines are called longitude.
Think about the two words that make up the term reproductive isolation. How do you think reproductive isolation affects the evolution of a species?
Answer:
Reproductive isolation refers to the inability of an organism or species to breed successfully with other organism or species.
It may arise from various factors such as:
Geographical isolation such as river, mountain, etcBehavioral changes such as mating time or season, mating rituals, mating location etc.Physiological differences such as change in shape of sex organs which causes lack of fit between copulatory organs.Genetic differences.Reproductive and geographical isolations between two populations (of same species) inhibit the flow of genes among them. Slowly, these isolations increase the variations in the gene pools of the two populations.
These genetic variations keep on increasing with time. In addition, as an adaptation to their surrounding or habitat the two populations would develop different behavioral and physiological changes
With time, these differences will increase up to such an extent that the two populations would not be able breed with each other. Hence, it would lead to the evolution of one or both the populations into new species.
PLATO:
Reproductive isolation refers to populations of organisms that have become isolated from each other. A geographical barrier or a genetic change can cause this isolation. As a result, the organisms are not able to successfully reproduce with each other. The two populations evolve separately from each other, likely developing different frequencies of genetic mutations and possibly selecting different traits.
consider the Wetland habitat pictured here imagine a very hot summer with very little rain what would the limiting factor for the populations of all the animals living here
Well, there wouldn't be really any water for the animals to drink.If it's very hot, and there is litte to no rain can cause bodies of water to evaporate so there will be less water to be drinken by the animials.If there in a drought there's not much they can do, just they can try consuming water when needed the most.If there is a good amount of water then they can drink whenever.If there would've been a bunch of rain they wouldn' have to worry, but in this case they have to worry because they don't have much water.
Limiting factors:
Little to no water due to drought.
Animals might die due to thirst.
The limiting factor for these animals is water. It is what they are missing because there is no rain.
