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.

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.

Think of two types of biomes and list them. Describe how they are similar. What are the differences between the two types of biomes?
Answer:
Dessert and tundra
Explanation:
Theses two biomes get very little rain and because of this they have a less diversity of fauna and flora.
The differences are that a tundra is very dry and extremely cold and on the other hand a desert is very arid and hot and it can go as high as 54°C (130°F).

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 process by which plant manufacture their food is called what?
Answer:
It is called photosynthesis
True/False: Cellular respiration just happens to plants because they use photosynthesis.
Numerous structures in the human body have evolved to maximize
surface area. These structures often take the form of folded anatomy
and help move important substances from the system they are found it
to the blood through the capillaries. Describe TWO examples of such
structures and EXPLAIN how they allow for the regular functioning of
the human body.
Answer:
Respiration begins at the nose or mouth, where oxygenated air is brought in before moving down the pharynx, larynx, and the trachea. The trachea branches into two bronchi, each leading into a lung. Each bronchus divides into smaller bronchi, and again into even smaller tubes called bronchioles.
4. Use your knowledge about the relationship between nutrients and photosynthesis to explain the trends you observed in the data.
Answer:
The trends go up in the presence of nutrients.
Explanation:
There is a great relationship between nutrients and photosynthesis because photosynthesis can't occur without without the availability of nutrients. Plants uses carbon from the atmosphere which is a nutrient whereas other nutrients such as nitrogen, phosphorus, potassium etc from the soil with the help of the roots. If these nutrients are available in the surrounding, the plant produced more food during photosynthesis because these nutrients are the food of plants so the trends go up in the presence of nutrients and lowers down in the absence or lower concentration of nutrients.
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.

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.
