Explanation:
Skeleton: provides support for its body
Backbone: provides support for its body
Exoskeleton: provides support to the stem and body
provides support and gives the body of the crab its shape,
So that leaves( Fur ) is your answer.
Fur is the structures in animals has a different function than the stem in plants. The correct option is D.
What are exoskeleton?In comparison to the internal skeleton of a human, an exoskeleton is an external skeleton that endorses and safeguards the body of an animal.
Some of the larger exoskeletons are referred to as "shells" in popular parlance.
The exoskeleton is made up of two layers: a thin outer nutrient layer called the epicuticle and a tough outer inner chitin-protein layer called the procuticle.
The epicuticle of most terrestrial arthropods, such as insects and spiders, contains waxes that aid in reducing evaporative water loss.
Hair and fur are molecularly indistinguishable because they are made of the same keratin.
Thus, the correct option is D.

What is the density of a metal cube that has a volume of 2 cm x 3 cm x 1cm and a mass of 12g? *
Answer:
Density of metal cube = 2 g/cm³
Explanation:
Given:
Dimensions of a cube = 2 cm x 3 cm x 1 cm
Mass of cube = 12 g
Find:
Density of metal cube
Computation:
Volume of a cube = 2 cm x 3 cm x 1 cm
Volume of a cube = 6 cm³
Density = Mass / Volume
Density of metal cube = Mass of cube / Volume of a cube
Density of metal cube = 12 / 6
Density of metal cube = 2 g/cm³

Which of the following could limit the growth of a population of squirrels in a local park?
A. Increase in the number of trees preferred by the squirrels for nests
OB. A decrease in the number of hawks, which prey on squirrels
C, Heavy rain causing an increase in acorns that the squirrels eat
OD. An outbreak of a disease that infects squirrels in the park
Answer:
D
Explanation:
They would be dying off, or leaving to get away from the disease
An outbreak of a disease that infects squirrels in the park could limit the growth of a population of squirrels in a local park. As the disease spreads and more squirrels become sick or die, the population growth rate will decline and may even become negative, leading to a decrease in the overall population size. Hence option D is correct.
What is an infectious disease?An infectious disease is a type of illness that is caused by a pathogen, such as a virus, bacterium, fungus, or parasite. These pathogens can enter the body and cause harm by multiplying and damaging the host's tissues.
Infectious diseases can spread from person to person, through contact with contaminated surfaces, via airborne particles, or through the bite of an infected animal. Some examples of infectious diseases include influenza, HIV/AIDS, tuberculosis, malaria, and COVID-19.
When an infectious disease spreads in a population, it can weaken or kill members of that population, thus decreasing the overall population size. The spread of the disease may be more rapid and widespread in populations that are densely packed, such as the population of squirrels in a local park.
The disease could be caused by a pathogen, such as a virus or bacteria, and could spread through direct contact or through contaminated food and water sources.
Hence option D is correct.

Based on the temperature data in the table which chemical reaction should the students use for their food carrier design
Answer:
Reaction 1
Explanation:
Reaction 1 would be the most suitable in this case. This is so because in reference to the question you are wanting to keep the food warm over long periods. So in reference to the data in the chart reaction 1 continues to heat up over long periods of time. However, with the other reactions (2, 3, 4) temperatures vary and some even decrease constantly. Therefore showing that the other reactions are invalid to help reach your goal referencing back to the question.

Which of these statements best explains why a nightly breeze blows toward the ocean in coastal locations?
Cool air above the land rises and displaces the cooler air above the ocean.
Cool air above the ocean rises, making room for warmer air from the land.
Warm air above the land rises and displaces the cooler air above the ocean.
Warm air above the ocean rises, making room for cooler air from the land.
Your answer is D: Warm air above the ocean rises, making room for cooler air from the land.
But, why? The short answer would be that during the night, the ocean loses heat and that heat goes into the atmosphere. As this happens, winds from the land blow towards the ocean to replace that heat, leading to that wonderful nightly breeze at the beach.

What interaction is there between the brown tree snakes and the birds, lizards, and bats?
Answer:
Predatory.
Explanation:
This is because the tree brown snakes feed on birds while the bats feed on the lizards.
This is so that the bats can eat lizards while the tree brown snakes can eat birds. The brown tree snake bites and grips its victim to paralyze it.
What is predatory behavior brown tree snakes and other?The predators of the brown tree snake are not widely known. According to some research, monitor lizards, feral pigs, and cats prey on brown tree snakes, and other.
Investigations have revealed that the species is also vulnerable to red-bellied black snakes and cane toads.
The snake encircles its victim's body with its own and begins to chew, allowing its teeth with grooves to release venom into the area.
Since mammals are less susceptible to the venom's effects than other animals, it is considered to be rather moderate.
Therefore, predatory interaction is there between the brown tree snakes and the birds, lizards, and bats.

Together, the stages of cellular respiration break down one molecule of Choose... to generate a total of Choose... molecules of ATP. The remaining energy is released as Choose... .
Answer: 1) Glucose
2) 36
3) Heat
Explanation: Cellular respiration is a metabolic process that every living organism undergo. It is the process by which energy is obtained by living cells. In the process of celluar respiration, energy-storing food molecule called Glucose is broken down in the presence of oxygen in order to release its energy and convert it to a usable form by the cell called ATP.
Celluar respiration occurs in three distinct stages in eukaryotes viz: Glycolysis Kreb's cycle and Oxidative phosphorylation. In Glycolysis, which occurs in the cytoplasm, glucose is broken down in a series of enzymatic reaction to yield Pyruvate and releasing a net gain of 2 ATP molecules. In Kreb's cycle, which occurs in the mitochondrion, produces carbondioxide in a two-cycled reaction involving Pyruvate. 2 ATPs are also produced in this stage.
Lastly, in Oxidative phosphorylation also occuring in the mitochondrion, electrons are passed through electron acceptors to create a pump that generates the synthesis of 32 ATP molecules. In general, the three stages yield a total of 36ATP molecules from one molecule of GLUCOSE.
The rest of the energy from the oxidation of glucose is lost as heat energy, which is responsible for the warming effect we feel. braibnliest??
