Answer:
-Cytokinesis.
Explanation:
Cell cycle can be defined as a series of cyclic events, which leads to formation of two daughter cells from a single parent cell. It is divided into two steps, interphase and M phase or mitotic phase.
During interphase, cell replicates its genetic material and prepares for cell division. Mitotic phase is divided into karyokinesis and cytokinesis.
During karyokinesis, division of nucleus takes place to form two daughter cells with same genetic composition. During cytokinesis, division of cytoplasm takes place that completes the cell division and forms two daughter cells.
Thus, the correct option to be filled in the blank is 'cytokinesis.
A good way for someone to identify similar substances is to measure their densities. true or false?
By how much did carbon dioxide levels increase from 1980 too 2000
The client is 24 weeks pregnant. how much have her daily calorie needs increased over her first trimester needs?
The male structure called the _____ is comparable to the ovaries in females
Which two structures of plants and fungi perform similar functions?
1.leaves and fruiting body
2.stem and hyphae
3.root and mycelium
4.stem and fruiting body
Answer: 3. root and mycelium
Plants are autotrophic organisms, which means they utilizes sunlight, atmospheric carbon and water, to prepare their own food in the form of carbohydrates. But these plants also requires some minerals like phosphorus, magnesium, nitrogen which are needed for their proper growth and metabolism. These plants obtain these minerals by absorbing them from the soil by the roots. Fungi are saprophytic organisms, which means they derive their food by decaying and decomposing the dead plants and animal traces. These fungi have thread like structures called as hyphae. The hyphae is responsible for penetrating the dead matter and obtaining nourishment. It functions like that of roots in plants. The aggregate of hyphae is called as a mycelium .
Therefore, both root and mycelium has a function in absorption of nourishment in the plants and fungi respectively.
Identify the producers in a terrestrial ecosystem compared to those in an aquatic ecosystem
Terrestrial producers are mainly land plants such as trees and grasses, while aquatic producers include algae and phytoplankton.
Producers, or autotrophs, are organisms that produce their own food using energy from sunlight or chemical sources. They play a crucial role in the ecosystems by serving as the base of the food chain.
Terrestrial Ecosystem Producers
In terrestrial ecosystems, such as forests, deserts, and tundras, the primary producers are land plants. These include trees, shrubs, grasses, and other plants that utilize sunlight through the process of photosynthesis to create organic compounds.
Aquatic Ecosystem Producers
In aquatic ecosystems, like oceans, lakes, and rivers, the main producers are algae and phytoplankton. These microscopic organisms perform photosynthesis and are responsible for a substantial portion of the Earth's oxygen production. They are quickly consumed by other aquatic organisms, contributing to high productivity despite their small biomass.
Both terrestrial and aquatic ecosystems have unique producers playing vital roles. While terrestrial ecosystems have larger, longer-lived plants, aquatic ecosystems rely heavily on microscopic phytoplankton, which are swiftly consumed but indispensable for marine life.
What important changes are occurring in the nucleus during the longest phase of mitosis?
Do you think ex-felons should be allowed to vote? If so, under what circumstances? If not, why not?
Answer:
Should ex-felons be allowed to vote? I honestly do not see a problem with ex-felons voting. I feel like we are taking away a basic right/amendment from our citizens if we do not allow them to vote. Especially if they have already been released from prison I cannot find much reason to not allow them to vote. I think that they should be allowed to vote only if they were released from prison. I mean I don’t really understand why they cannot vote, but in conclusion I think they should be able to vote.

what type of cloud is associated with hail
Hail is associated with cumulonimbus clouds, which are large, tall clouds that can span up to the stratosphere and are known for causing severe weather such as thunderstorms.
Explanation:The type of cloud associated with hail is the cumulonimbus cloud. These clouds are also known for producing thunderstorms, and they have a distinctive anvil shape at their tops due to high winds at higher altitudes. Hail forms when updrafts in thunderstorms carry water droplets upward into extremely cold areas of the atmosphere where they freeze into ice. The process of the water droplets being carried up and down through various levels of the storm, accumulating layers of ice, eventually results in the formation of hailstones. When the hailstones become too heavy for the updrafts to support them, they fall to the ground as hail.

Jose's lunch contains 121 grams of carbohydrate, 40 grams of protein, and 25 grams of fat. what percent of kilocalories in this meal come from fat?
Answer:
[tex]25.89[/tex]% is the percent of kilocalories in this meal that come from fat
Explanation:
Amount of calories in one gram of carbohydrate [tex]= 4[/tex]
Amount of calories in one gram of protein [tex]= 4[/tex]
Amount of calories in one gram of fat [tex]= 9[/tex]
Now total calories in [tex]121[/tex] grams of carbohydrate
[tex]= 121*4\\= 484[/tex]
Now total calories in [tex]40[/tex] grams of protein
[tex]= 40*4\\= 160[/tex]
Now total calories in [tex]25[/tex] grams of fat
[tex]= 25*9\\= 225[/tex]
Total calories [tex]= 225 + 160+ 484\\= 869[/tex]
one kilocalories is equal to [tex]1000[/tex] gram calories
Total kilocalories is [tex]= 0.869[/tex]
Total kilocalories in fat [tex]= 0.0.225[/tex]
Thus, percent of kilocalories in this meal come from fat
[tex]\frac{0.225}{0.869}* 100\\= 25.89[/tex]%
Explain three ways that human activity negatively affects Earth’s natural resources.
Natural resources are the resources that are present in environment for the use of human. There are many ways in which the human activity is negatively affecting the natural resources. Among other activities, three activities are:
1 Deforestation : Cutting down of trees in large numbers leads to deforestation. Trees are of great importance in terms of oxygen, medicine, wood and other products. Human interventions is leading to destruction of natural resources. Trees are cut in large numbers for the sake of these products from it and the rate at which the deforestation is increasing, it will lead to some serious issues in future.
2 Water Pollution : Water is a vital substance for the life of organisms. Human interventions are polluting the water at a very high rate.The aquatic life is hampered by water pollution. The percentage of water available for human consumption is decreasing due to wastage and pollution of water.
3 Over consumption of coal and petroleum: The coal and petroleum are consumed by the humans in such a way that there are possibilities that the future generation might not see it. The over consumption of fossils fuels is a very serious problem caused by human activity.
If carbon dioxide and water were abundantly available to a heterotrophic prokaryotic cell, would it be possible for the cell to use them as a food source?
Answer:
No, it would be impossible
Explanation:
Heterotrophs are so called because they cannot synthesize their own food, they depend on an external source. The synthesis of food is unique to a particular set of organisms called AUTOTROPHS. They have the ability to capture the energy from sunlight using pigments called CHLOROPHYLL and use this energy to synthesize their food in their Chloroplast. This process is called PHOTOSYNTHESIS. Autotophs combine CO2 and H2O (water) to produce glucose (organic molecule).
Heterotrophs like animals, do not possess this ability to capture sunlight energy or fix carbon to produce their food. Hence, in an abundance of CO2 and water, their cells would be unable to utilize these molecules, as only the Chloroplast of autotophs can undergo this process.

Compare the biodiversity in an oligotrophic lake with a eutrophic lake
Oligotrophic lakes have low nutrient levels and lower biodiversity, with clear water and fewer plankton. Eutrophic lakes have high nutrient levels leading to algal blooms, which can cause oxygen depletion and disrupt aquatic life. While eutrophic lakes may have diverse ecosystems initially, their long-term health can be compromised by excessive nutrient input.
Explanation:Comparing the biodiversity in an oligotrophic lake with a eutrophic lake involves examining the differences in their ecosystems due to nutrient levels. An oligotrophic lake has low nutrient concentrations, resulting in clearer water with fewer phytoplankton. The low levels of nutrients such as nitrogen and phosphorus mean that these lakes often have less overall biological productivity and hence lower biodiversity. In contrast, eutrophic lakes are characterized by high levels of nutrients, often attributed to runoff containing fertilizers or sewage. This leads to a rapid growth of algae and phytoplankton, known as algal blooms, which may eventually result in oxygen depletion as dead algae decomposes. Consequently, eutrophic lakes often have higher initial biodiversity, but the excessive growth and subsequent oxygen depletion can lead to dead zones, significantly harming aquatic life.
For example, eutrophication in Dianchi Lake, China, caused by fertilizer pollution, led to fish kills due to oxygen depletion. This illustrates the negative impact of nutrient overload on lake ecosystems. Another impact is that deep zones in eutrophic lakes may become aphotic and unable to support photosynthetic plant life. However, in the open-water and littoral zones of lakes, sunlight promotes plant growth and supports various organisms such as fish, snails, and insects.

List examples of carbohydrates, lipids, proteins, and nucleic acids and name the function of each
Biological macromolecules play a crucial role in the structure and function of living organisms. They are divided into four main categories: carbohydrates, lipids, proteins, and nucleic acids.
Carbohydrates are composed of carbon, hydrogen, and oxygen, and they serve as the body's primary source of energy. Examples include glucose, sucrose, and starch. Their function is to provide energy and structural support in cells.Lipids are nonpolar molecules that include fats, oils, and cholesterol. They serve as long-term energy storage, make up cell membranes, and can be hormones. Examples of lipids are triglycerides, phospholipids, and steroids.Proteins are made of amino acids and perform a wide range of functions such as acting as enzymes, hormones, and antibodies. Examples of proteins include hemoglobin, insulin, and antibodies.Nucleic acids include DNA and RNA, which store and transmit genetic information. DNA holds the instructions for protein synthesis while RNA translates these instructions to produce proteins.Many diseases are best understood as disturbances of
