Answer:
1. Metaphase
2. Prophase
3. Telophase
4, 5, 6, 8. Interphase
7. Anaphase
Explanation:
Mitosis is a cell division involving the formation of two genetically daughter cells. The process of mitosis involves stages including: interphase, prophase, metaphase, anaphase and telophase.
Interphase is the resting stage of the cell. It is th stage where the cell prepares for the division. Numbers 4, 5, 6, and 8 in the image are stages of interphase.
Prophase is the stage where the chromosomes become visible and arrange in pairs. Number 2 in the image depicts a plant cell in prophase stage.
Metaphase is the stage where the chromosomes align at the equator/middle of the cell. This alignment orients the chromosomes for separation. Image 1 depicts this metaphase stage.
Anaphase stage is the stage where the chromosomes separate into opposite poles of the cell. Image 7 depicts the anaphase stage of this plant cell.
In the Telophase stage, the cell plate forms to divide the plant cell into two. This is shown in image 3.
As a result of the non-selectivity of kidney's filtration of small molecules, useful substances must be selectively reabsorbed to the blood. Filtration is the mass movement of water and solutes from plasma to the renal tubule that occurs in the renal corpuscle. About 20% of the plasma volume passing through the glomerulus at any given time is filtered. Glomerulus lets fluid and waste products pass through it, however, it prevents blood cells and large molecules, mostly proteins, from passing.
Answer:
Answer 1: <em>Producers</em> represent the most biomass in an ecosystem.
Answer 2: <em>Human and animal respiration, decomposition and volcanic eruptions</em> are natural sources of carbon emissions.
Explanation:
Answer 1: <em>Producers</em> represent the most biomass in an ecosystem.
Producers refer to plants, trees, shrubs, etc., that make up the first trophic level of an ecosystem. Producers are vital to ecosystems as they produce food for themselves as well as primary consumers. Producers represent the most biomass in an ecosystem as they are the first trophic level in an ecosystem. As we go up trophic levels in an ecosystem, only 10% of energy as biomass is passed on to the next trophic level. Thus, producers represent the most biomass in an ecosystem.
Answer 2: <em>Human and animal respiration, decomposition and volcanic eruptions</em><em> </em>are natural sources of carbon emissions.
Respiration is a natural source of carbon emissions as, when humans and animals exhale, they release carbon dioxide and water vapor in the atmosphere. Similarly, when plants and animals die and decompose (decay), carbon dioxide is released in the atmosphere as part of the decomposition process. Thirdly, volcanic eruptions are also a significant form of carbon emissions as annually, 200 million tonnes of carbon dioxide is released from the earth's interior when volcanoes erupt. In this way, human and animal respiration, decomposition and volcanic eruptions are natural sources of carbon emissions.
Aerobic means “with oxygen” and anaerobic means “without oxygen”
Answer:
Iris.
Explanation:
Eye is one of the most important sense organ of the body that helps to receive the light and also helps in the maintenance of the body equilibrium. The pupils regulate the amount of the light that enters in the eyes.
The Leslie has some eye problem and doctors use a sedative in her eyes. The sedative drug has the largest effect on the iris of the eye. The iris decides the color of the eye and also regulate the proper functioning of the pupil of eye.
Thus, the correct answer is iris.
