Create a food chain using the following: algae, tadpole, minnow, sun, Blue Heron, alligator. Make sure to include the arrows pointing in the correct direction.
Answer:
sun-->algae--> tadpole--> minnow-->Blue Heron--> alligator
Explanation:
The food chain for the following is: sun ---> algae ---> tadpole ---> minnow ---> Blue Heron ---> alligator.
What is food chain?"Food chain is the sequence of transfers of matter and energy in the form of food from organism to organism."The food chain of the given organisms is as follows:
The sun is the ultimate source of energy. In its presence the green plants and algae make their own food.Tadpole is the larva of frog which gets its nutrition from the algae.Minnow are small fishes which eats larva. These are being eaten by blue heron (bird).At last the blue heron gets eaten by alligator.The interconnection of more than one food chains are called food web.
Hence, the correct sequence is: sun ---> algae ---> tadpole ---> minnow ---> Blue Heron ---> alligator.

Aerobic and Anaerobic Cellular Respiration
Answer:
The correct answer is - aerobic cellular respiration, oxygen, anaerobic cellular respiration, energy, lactic acid and muscle fatigue.
Explanation:
The most common type of cellular respiration is aerobic cellular respiration which takes place in the condition where enough amount of oxygen is available that provides energy to the body.
In absence of enough amount of oxygen the anaerobic cellular respiration, when an individual exercise intensely his body not able to provide enough amount of oxygen to the cells so, therefore, perform anaerobic respiration to produce energy however this cause muscle fatigue due to a byproduct known as lactic acid.

A) standardization
B) reliability
C) validity
D) brevity
Answer:
D) brevity
Explanation:
A test can be defined as an examination or quiz given to a student (pupil) during an academic calendar in order to measure or determine his or her intelligence. It is usually graded based on a set of defined grades or scores.
The key characteristics of a well-designed test includes the following;
I. Standardization: it is important that test is set based on certain criteria and acceptable rules within the education community and curriculum.
II. Reliability: the questions contained in a test should be credible and backed by correct answers.
III. Validity: the test questions should be genuine and authentic across board.
However, brevity simply means succinctness or conciseness i.e the test should be brief and very short in duration.

You decide to create a composting bin for your house. While checking on it one day, you notice that the compost bin has started to smell like rotting eggs. You know that a successful compost bin should not smell like this. You take a sample of the pile and check for the presence of microorganisms under the microscope. You see that there are indeed microorganisms. Given this information, what should you do to resolve the smell of your compost?(1 point)
Creating a tent for the pile to shield it from the sun and heat will help resolve the smell.
Turning the pile to aerate the compost and expose it to oxygen will help resolve the smell.
Adding more “brown” materials to the pile to increase the amount of carbon will help resolve the smell.
Adding more “green” materials to the pile to increase the amount of nitrogen will help resolve the smell.
Answer:
Turning the pile to aerate the compost and expose it to oxygen will help resolve the smell

Sort the sentences based on the type of relationship they describe. Sea lampreys hatch eggs on fish and feed on the fish. Clown fish help sea anemones catch prey while using the sea anemones for protection. Mosquitoes suck blood from the bodies of organisms. Ants provide protection to acacia trees while receiving nutrients from the trees. Mutualism Parasitism Ants reserved PLZ HELP
Answer:
1: Parasitism
2: mutualism
3: parasitism
4: mutualism
Explanation: Hope this helps and have a great day!!
The sentences describe different types of symbiotic relationships between organisms are: Parasitism, Mutualism, Commensalism
1. Parasitism: Sea lampreys hatch eggs on fish and feed on the fish.
In parasitism, one organism benefits (the sea lampreys) at the expense of the other (the fish) by feeding on its tissues.
2. Mutualism: Clownfish help sea anemones catch prey while using the sea anemones for protection.
This sentence describes mutualism, where both clownfish and sea anemones benefit from the relationship. Clownfish protect sea anemones from predators, while they, in turn, provide a safe haven for the clownfish.
3. Parasitism: Mosquitoes suck blood from the bodies of organisms.
Mosquitoes exemplify parasitism as they feed on the blood of other organisms, taking nutrients without providing any benefit in return.
4. Mutualism: Ants provide protection to acacia trees while receiving nutrients from the trees.
This sentence represents mutualism, where ants defend acacia trees from herbivores, and in return, they receive nutrients and shelter from the trees.
5. Commensalism: Ants reserved.
The term "reserved" here seems to be incomplete, but assuming it refers to ants residing in a certain place, it would represent commensalism. Commensalism describes a relationship where one organism benefits, and the other is neither helped nor harmed significantly.
In summary, the sentences describe mutualism, parasitism, and possibly commensalism, showcasing the diverse interactions that can occur in ecological communities.

The best way to practice sustainable use of rangelands is to
Answer: 1. Rotating the rangelands that are being used.
2. Reducing overgrazing of rangelands.
Explanation:
Rangelands are the sites which are occupied and dominated by vegetation cover mostly the shrubs and herbs. It can be occupied by grasses. Overgrazing by the cattle cause a huge damage to the field of rangeland so it can cause soil erosion and can convert the rangeland on barren land. The regrowth rate is slower than that of the consumption rate of the cattle. So, reduction in overgrazing is advisable to maintain the sustainability of the land. Rotation of the rangelands being used if the cattle are taken to the different grassland for grazing on alternate days then the rangelands can be maintained sustainably.
For a population to be in Hardy-Weinberg equilibrium, the population must
be small.
not experience migration.
have new mutations.
have nonrandom mating.
Answer:
The population must be at carrying capacity
Explanation:
Hardy-Weinberg equilibrium has a set of conditions that must be met in order for the population to have unchanging gene pool frequencies. There must be random mating, no mutation, no migration, no natural selection, and a large sample size.
It is not necessary for the population to be at carrying capacity. The population can grow or shrink while maintaining the gene pool.
For a population to be in Hardy-Weinberg equilibrium, the population must not experience migration. Thus, the correct option is B.
What is Hardy-Weinberg equilibrium?The Hardy-Weinberg principle is also known as the Hardy-Weinberg equilibrium, or law, which states that the allele and also the genotype frequencies in a population will remain constant from one generation to next generation in the absence of other evolutionary influences, as well.
There are five basic Hardy-Weinberg assumptions no mutation, random mating, no gene flow, infinite population size, and no selection.
For a population to be in Hardy-Weinberg equilibrium, the population must not experience migration.
Therefore, the correct option is B.
