What is the difference between food chains and food webs? Food webs show the flow of energy from producers to consumers, and food chains show the flow of energy from consumers to producers. Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem. About ten percent of the energy is passed on to the next trophic level in food webs, but in food chains, about ninety percent is passed on to the next trophic level. Heat is lost when energy is passed on to the next trophic level in food chains, but in food webs, heat is not lost when energy is passed on to the next trophic level.

Answer:

Built well where water table present nearer to surface.

Explanation:

My advice for them about determining the placement and potential effectiveness of the well is that the well should be installed where the groundwater present nearer to the surface, the reason behind this advice is that minimum work and energy will be used for digging well. If the water table is present very deep, more work and energy will be utilized on the digging of the well. Those areas where more rainfall occurs, the depth of water table is less as compared to arid zones because due to more rainfall more water goes inside the soil and the water table rises.

Answer:

Genetic = yes

Infectious = no

Potentially lethal = yes

Inherited = yes

Explanation:

"Sickle Cell Disease" is a blood disorder that is mostly inherited. An example of this is the "Sickle Cell Anemia," which means the body of the person is lacking in red blood cells. In order for an infant to carry such disease, both of his parents must pass the defective gene to him. It is a potentially lethal or deadly disease because if not given remedy, it may lead to several complications such as organ damage, leg ulcers, blindness, etc.

It is not infectious, which means that a person with a Sickle Cell Disease cannot transfer it to another person. It is not likely to spread as well.

Answer:

The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).

Explanation:

Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.

- Claim: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.

- Evidence: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.

- Reasoning: cohesion in water depends on the force of attraction between H₂O molecules, adhesion is the capacity of H₂O molecules to join other different molecules and —together with surface tension— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.

The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.

Answer:

B. All of the fish, bacteria, and mammals that live in a lake

Explanation:

In terms of biology an individual make population, population makes a species and interaction between different species makes community. Interaction of living and non-living things make an ecosystem.

Community involves interaction between all the living organisms present in a given environment. Hence, interaction between fish, bacteria, and mammals that live in a lake is a community.

Hence, the correct answer is "B. All of the fish, bacteria, and mammals that live in a lake".

Explanation:K12

Answer:

Genes are portions of DNA that contains information to encode proteins

Alleles are different forms of one gene

Chromosomes are closed circular DNA molecules that contain the genetic material of an organism

Explanation:

Genes can be defined as regions of DNA which are transcribed to produce messenger RNAs (mRNAs) by a process known as transcription. Subsequently, these mRNAs are translated into proteins. In diploid organisms, each gene contains two different forms called alleles. A chromosome is a long DNA molecule that contains part or even the entire genetic material of an organism. In diploid organisms, one chromosome contains one allele (inherited from one parent), while its homologous chromosome pair contains another allele of the same gene (inherited from the other parent).

Explanation:

Answer: In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP +, respectively.

Answer:

Glucose is a reactant of cellular respiration.

Carbon dioxide and water are both products if cellular respiration.

Note: The question is incomplete. The complete question is given below:

Identify whether each item is a reactant or a product of cellular respiration. glucose carbon dioxide (co2) water (h2o)

Explanation:

Cellular respiration is the process by which glucose is broken down by the cells to produce the energy molecules, ATP.

The various reaction steps of cellular respiration include glycolysis- where glucose is broken down into two molecules of pyruvate, the citric acid cycle- where two acetylCoA molecules produced from the oxidation of pyruvate are converted to carbon dioxide molecules, and finally the electron transport chain- where the electron-donors NADH and FADH2 produced in the citric acid cycle donate their electrons to oxygen to produce water molecules.

The overall chemical reaction for cellular respiration is represented as follows:

C6H12O6 + 6O2 → 6CO2 + 6H2O

1 molecule of glucose reacts with six molecules of oxygen to produce six molecules of carbon dioxide and six molecules of water.

Therefore, glucose is a reactant while carbon dioxide and water are both products of cellular respiration.

The answer is they passed the Jim Crow Laws, D

The 14th and 15th Amendments protected African Americans' right to citizenship and the right to vote. Southern States passed "Jim Crow laws" to suppress black voters and maintain segregation. Thus option D  is correct.

During  the 1880s and 1960s, a majority of American states are forced to segregation through a law called jim crow law which was applied From Delaware to California, and from North Dakota to Texas, many states   impose legal punishments on people for consorting with members of another race.

some of the common types of laws forbade intermarriage and ordered business owners and public institutions and separate their black and white clientele.

This law is a part of  of American history with having been enacted at the state and local levels to mandate and maintain racial segregation in the southern United States.

The  Jim Crow Laws are economic, social, and educational woes that blacks living in the South have been forced to live with for decades.

Answer:

Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome .

The process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.

In conclusion, the process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.
