What is the benefit of an arthropod’s exoskeleton.
Question 5 options:
A. It allows arthropods to breathe.
B. It protects and supports the arthropod’s body.
C. It allows the arthropod to get food.
D. It allows the arthropod to see far distances.
Answer:
B
Explanation:
Beyond support, the exoskeleton provides protection against predators and strength against prey. And it protects arthropods from the environment, for example, keeping ocean-dwellers from being affected by small changes in saltiness and preventing land-dwellers from drying out.

Matter constantly cycles through the earth's spheres using many different processes. Photosynthesis and cellular respiration are
two important processes in this cycling of matter. The products of photosynthesis are reactants in cellular respiration. The
products of cellular respiration are the reactants of photosynthesis. This model shows the cycling of matter through these cycles.
The model is unlabeled. Correctly label the products and reactants of cellular respiration. Choose ALL that apply.
A)
A = ATP
B)
B = CO2 + H20
C
A = C6H1206
D)
D = 02 + C6H1206
E)
B = 02 + C6H1206
Answer:
A) A = ATP
B) B = CO2 + H2O
D) D = O2 + C6H12O6
Explanation:
The process of photosynthesis and cellular respiration mutually depends on one another. In this diagram, A represents ATP, B represents C[tex]O_2[/tex] + [tex]H_2O[/tex], C represents sunlight, and D represents [tex]C_6H_1_2O_6 + O_2[/tex].
What do you mean by Photosynthesis?Photosynthesis may be defined as a process through which plants synthesize their own food with the help of carbon dioxide and water in the presence of sunlight.
Mitochondria release energy in form of ATP, while carbon dioxide and water serve as the reactant for photosynthesis. In presence of sunlight, they convert into glucose and oxygen which is the product of photosynthesis.
Both photosynthesis and cellular respiration mediate the cycling of matter like oxygen, glucose, carbon dioxide, etc.
Therefore, it is well described above.

Which statement describes the best evidence that two species share a recent common ancestor?
A) The species are about the same size.
B) The species eat the same type of food.
C) The species live in the same ecosystem.
D) The species have similar DNA sequences.
Answer:
I hope this helps you :)
Explanation:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
The statement that describes the best evidence that two species share a recent common ancestor is that the species have similar DNA sequences, which is present in Option D, as the DNA is the genetic material.
What role does the DNA sequence play in evolution?DNA sequence comparisons have become an increasingly important tool in determining evolutionary relationships between organisms, and after comparing the DNA sequences of different organisms, scientists can determine the degree of similarity between them such as similarities in size, diet, or ecosystem may indicate some degree of similarity between two species, but they do not necessarily provide evidence for a recent common ancestor.
Hence, the statement that describes the best evidence that two species share a recent common ancestor is that the species have similar DNA sequences, which is present in Option D.

Winds blowing in opposite directions form a cylinder that might get tipped up by a supercell’s ________.
A. gravitational pull
B. eye
C. updraft
D. fog
Plz Help!!! God Bless You
Winds blowing in opposite directions form a cylinder that might get tipped up by a supercell’s updraft.
What do you mean by updraft?Updrafts are found when a wind blowing at a hill or mountain has to rise to climb over the hill. Updrafts can also be caused by the sun heating the ground. The heat from the ground warms the surrounding air, which causes the air to rise. The rising pockets of hot air are called thermals.
The definition of an updraft is a strong upward current of air. When a big gust wind comes along and catches on the umbrella on your outside table from underneath, knocking your umbrella and table over with its power, this big gust of wind is an example of an updraft.
When warm, moist air moves upward in an updraft, puffy cumulus clouds may form in the atmosphere. The moisture in the air condenses into water droplets as it rises. The cloud will continue to grow as long as warm air from below continues to rise.

What do you mean by metabolism?Metabolism is the set of life-sustaining chemical reactions in organisms. The three main purposes of metabolism are: the conversion of the energy in food to energy available to run cellular processes.
Moreover, it is the process by which the body changes food and drink into energy. During this process, calories in food and drinks mix with oxygen to make the energy the body needs. Even at rest, a body needs energy for all it does.
Hence, if your metabolism is "high" (or fast), you will burn more calories at rest and during activity. A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.

Which consequence is a direct result of human population growth
Answer:
One of the largest environmental effects of human population growth is the problem of Global warming.
Economic development, urbanization, energy consumption, transportation/motorization due to rapid population growth are major driving forces of air pollution in large cities.
In order to support the growing population, forests are being destroyed at an alarming rate. Deforestation occurs when humans clear forests to use the land either for agriculture or for habitation. This leads to soil erosion and the extinction of plant species. Land animals also decline in numbers and even face extinction due to human expansion that encroaches on their natural habitat and limits their ability to spread geographically.
Humans also continue to put a great demand on the natural resources of our planet. Many non-renewable resources are being depleted due to the unrestrained use of fuel and energy. Many parts of the world also suffer from a shortage of food and water.
The growth of the population puts larger demands on our already limited resources. The environment on earth is suffering from the growth of the global population. The depletion of resources and biodiversity, the production of waste, and the destroying of natural habitat are serious problems.
