It is called it's biomass.
Hope this helps!
Biomass refers to the total amount of organic matter present in any trophic level and plays a key role in energy transfer within an ecosystem.
Explanation:The total amount of organic matter present in any trophic level is referred to as biomass. This is the total weight, at the time of measurement, of living or previously living organisms in a unit area within a given trophic level. For instance, in an ecosystem like the English Channel, the primary producers (such as plants) account for a biomass of 4 g/m², while the primary consumers (such as herbivores) exhibit a biomass of 21 g/m².
Biomass is a significant factor in the study of ecosystems and biogeochemical cycles as it helps determine the amount of energy that is transferred from one trophic level to the next. It is essential to understand that energy flows directionally through ecosystems, from primary producers up to apex consumers.

18. Sam’s mother has type O blood. Her father is type B blood, with the genotype BO. What are the possible blood types that Sam could have? (use scratch paper to make a punnett square)
Final answer:
Sam could potentially have Blood type B or Blood type O, due to the genotypes of his parents. His mother's ii genotype and his father's BO genotype limit the possibilities to these two types, with Blood type A and Blood type AB being impossible in this scenario.
Explanation:
When considering the ABO blood groups, a person's blood type is determined by the alleles they inherit from their parents. Sam's mother has type O blood, which means her genotype is ii, as O is recessive. Sam's father has type B blood with a genotype of BO, where B is dominant and O is indicated by the allele i. To determine the possible blood types for Sam, we can construct a Punnett square. The mother can only contribute the i allele, and the father can contribute either B or i. This results in two possible genotypes for Sam: Bi (which would result in Blood type B) or ii (which would result in Blood type O). Other types, such as Blood type A or Blood type AB, are not possible with these parental genotypes.

An energy pyramid is a graphical model of energy flow in a community. The different levels represent different groups of organisms that compose a food chain. An energy pyramid’s shape shows how the amount of useful energy that enters each level. Chemical energy, in the form of food, decreases because some is used by the organisms in each level. The source of the chemical energy is the producers, that rearrange carbon dioxide and water in the presence of light to make ________ through the process of ______________.
An energy pyramid depicts the decline in energy, biomass, and organism numbers across trophic levels within an ecosystem. Producers use photosynthesis to create energy, which is then passed up the food chain with a significant loss at each step, leading to a maximum of four or five trophic levels.
Explanation:An energy pyramid is a graphical model illustrating the energy flow within an ecosystem. The various levels of the pyramid represent different trophic levels in a food chain, starting from the producers at the base to the apex predators at the top. Producers utilise sunlight to create chemical energy through the process of photosynthesis. This energy is then transferred to the primary consumers and subsequently to higher trophic levels, although with a significant energy loss at each step. Typically, about 90% of the energy is lost, mostly through metabolic processes and as heat, with only about 10% being passed to the next level. This energy loss is the reason why energy pyramids are always upright and why there are usually no more than four or five trophic levels, as there simply isn't enough energy to support additional levels.
The ecological pyramid provides a visual representation of the decline in energy, biomass, and number of organisms from lower to higher trophic levels. Assuming that producers in an ecological pyramid have 1,000,000 kilocalories of energy, only about 10% of this energy, or 100,000 kilocalories, would be available to the primary consumers. This continues up the pyramid, with further reductions at each subsequent level.
what type of sample can give information on how long someone has been exposed to a poison? Blood Muscle Hair
They would need to give a Blood sample. If someone gives a blood sample, whoever is testing it, can tell a large number of things. (ex. if you're dehydrated, how many red blood cells to white blood cells ratio, if you have a vitamin deficiency, and a ton of other things.) They will be able to tell how long you've been exposed to something poisonous because they will be able to see the changes that the poison has made to the blood stream, and the way it affects it.
Hope this helps!! (:
Final answer:
Hair samples are the most informative for determining how long someone has been exposed to a poison because they encapsulate a chronological record of exposure, unlike blood or muscle tissue which reflect recent exposures.
Explanation:
When it comes to understanding how long someone has been exposed to a poison, hair samples can provide valuable information. As hair grows, substances such as toxins can be deposited in the hair shaft, providing a chronological record of exposure. This is why hair analysis is often used in forensic toxicology when assessing long-term low-level exposure to toxins such as heavy metals, including arsenic, mercury, and lead. Blood and muscle tissues do not provide as clear a historical record of exposure because they are more reflective of recent exposures rather than a long-term timeline.

what is the relationship between the properties of water and transpiration that takes place in plants?
Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. hope this helps and plz friend me im jake and im 13
The process through which the water is released from the plant to the environment is called as transpiration. The water from the root is passed on to the leaf surface through xylem by capillary action of water.
The water exhibits capillary action due to properties such as surface tension, cohesion, and adhesion. With the help of adhesion property, the water molecules binds with the xylem wall molecules, due to cohesion, the water molecules bind with one another and facilitates continuous as well as easy movement from root to the leaf through stem.

which event does not need to take place before meiosis can begin
DNA Replication maybe?
The event not required before meiosis begins is the formation of the gametes (option A), which occurs after meiosis during gametogenesis. Instead, chromosome duplication, cytoplasm increase, and organelle production occur during interphase prior to meiosis to prepare the cell.
The event that does not need to take place before meiosis can begin is A. The formation of the gametes. Gametogenesis is the process that occurs after meiosis where haploid cells develop into mature gametes capable of fertilization. Prior to meiosis, however, the cell must undergo certain preparatory steps during interphase. These include B. The production of cell organelles, C. The production of more cytoplasm, and importantly, D. The duplication of the chromosomes. This ensures that the cell has all the necessary components for the two subsequent rounds of cell division, which will ultimately produce four haploid daughter cells from one diploid parent cell.
During interphase, specifically the S-phase, DNA duplication occurs, which is essential for providing each daughter cell with the correct number of chromosomes. The increase in cell size and organelle duplication are also part of the cell's preparation for division. However, the separation of sister chromatids does not occur during interphase; it occurs later during the actual process of meiosis.

Fernanda is working on a physics project. She is experimenting by rolling a marble down a ramp and then seeing how far it rolls along the floor after leaving the ramp.Which would be the dependent variable in Fernanda’s experiments?
The physics project on which Fernanda is working is the rolling a marble down a ramp and observing the distance marble would roll along the floor after leaving the ramp.
Each experiment has an independent and a dependent variable. Independent variable is one whose change is not controlled by the change in another variable or factor. Dependent variable is the one which is measured or determined in any experiment, it varies depending on the changes in independent variable.
In the given experiment, the dependent variable is distance the marble rolls after leaving the ramp as the distance marble rolls depends on the angle at which marble is released on the floor or the material with which the marble is made or the size of the marble. So the independent variable can be any of those, angle at which marble is released on the floor or the material with which the marble is made or the size of the marble.
Answer:
The distance the marble rolls after the ramp
Explanation:

Cnidarian bodies are either in the polyp or medusa form with tentacles surrounding the mouth. What type of symmetry do they have
a)
radial
b)
asymmetrical
c)
bilateral
Answer:- Option a radial symmetry
Explanation:-
Most of the organisms have can either of the two types of symmetry:-
1. Bilateral symmetry- A body is said to have a bilateral symmetry when it can be divided into 2 equal halves on either side of a single plane.
For e.g if you cut the letter M from middle vertically then you have two equal halves.
2. Radial symmetry - A body is said to be radially symmetrical if it can be divided into similar halves in any plane. This means that the organism has its body parts arranged around a central main axis.
The cnidarians whether in polyp or medusa from exhibit radial symmetry because if you cut them in any plane you will get equal halves.

One hypothesis regarding the extinction of dinosaurs is that a meteor hit the earth causing an explosion so powerful that dust blocked out the sun. Consider the model above and explain why would this have caused a mass extinction?
There is no model visible, but the main theory as to how an asteroid/meteor impact would cause a mass extinction is that the force of the projectile landing onto the surface of the earth would launch so much debris and material into the atmosphere that it would block out most if not all light from the sun, leading to a inevitable food pyramid crash. As the producers die and become harder and harder to find, primary consumers decline which leads to the decline of secondary consumers, and so on until you reach the apex predators in the ecosystem(s).

describes one of Isaac Newton's contributions to the world of science
Final answer:
Isaac Newton made monumental contributions to physics, including formulating the laws of motion and the law of gravity, inventing calculus, and improving the theories of light and color, which remain foundational in physical science.
Explanation:
Isaac Newton's Contributions to Science
Sir Isaac Newton (1642-1727) was a pivotal figure in the history of science, making groundbreaking contributions across several fields. His most renowned work, the Philosophiae Naturalis Principia Mathematica, laid the foundation for classical mechanics through his laws of motion and the universal law of gravity. Besides these achievements, Newton invented calculus, which is fundamental to advanced mathematics and engineering, and greatly advanced the theories of light and color, impacting the field of optics.
Newton's laws of motion established a formulaic way to predict the movement of objects both on Earth and in space, marking a significant transformation from the Renaissance to the modern era of thought about the physical universe. This was a move away from the theologically-intertwined science of the past towards a model based on empirical evidence and mathematical precision. Through his work, Newton distilled the Scientific Revolution's findings, building upon the legacies of predecessors like Galileo and Kepler, to provide a comprehensive framework that remains influential in physics today.
Newton's methods and theories emphasized the importance of basing scientific inquiry on observation and experimentation rather than on established authority or solely philosophical reasoning. This approach was integral to the advancement of the Scientific Revolution, setting the stage for the modern scientific method.

D.
all of these
A is the correct answer because we want more diversity in ecosystems and also animals going extinct is not good
Answer:
A. The water cycle ensures that water used by one organism will be available for another organism in the future.
Explanation:
Water is a crucial substance for life on earth. The water cycle is extremely important for the sustainability of living systems, because it collects, purifies and distributes the fixed amount of water on the planet. Through the water cycle the water used by one organism will be available to another organism in the future.
The water cycle is powered by the sun's energy and involves three major processes: evaporation, precipitation and transpiration. Solar radiation causes evaporation of water contained in oceans, lakes, rivers and soil. Evaporation transforms liquid water to water vapor, and later gravity causes water to return to the earth's surface as precipitation. On land, 90% of the water that reaches the atmosphere evaporates from the plant surface through the process of evapotranspiration and from the soil.
Water that returns to the earth's surface as precipitation follows different paths. Most of the precipitation that occurs on terrestrial ecosystems flows superficially and gathers to form rivers and streams. Some of this surface water seeps into the upper layers of the soil and is used by plants and some of it evaporates from the soil into the atmosphere. Some precipitation is converted to ice and stored in glaciers, usually after long periods of time. Some precipitation seeps into the soil and permeable rocks and is stored as groundwater in geological formations called aquifers. A small portion of the water is used by living things.
