What are the behavioral adaptions of an animal from the ocean, animal from the desert, animal from antartica and animals from rain forest
Answer:
1. Some fish like stargazer fish hide in rocks and sand to catch prey; some paralyze other fishes or some other ocean animal for safety and food, some like remora fish attach to larger fishes like sharks for protection and food.
2. Some desert animals like kangaroo rats can survive their whole lives without drinking water as they obtain all the moisture they need from the food in their diets.
3. Emperor penguins found in Antarctica form large, ever-moving huddles that allow them to share body warmth, and shelters them from the cold wind.
4. The sloth, an animal found in treetops uses camouflage and moves very slowly to make it difficult for predators to spot.
Explanation:
Adaptation refers to characteristics that help an organismmto be better suited for survival in their environment. Some adaptations may be physical such as the possession of limbs for movement by some animals, physiological such as production of toxins by some plants to avoid being eaten, or behavioural such as building a nest by birds
1. Fishes are animals that live in the ocean. Behavioural adaptations are the way different fish act to survive. Some fish like stargazer fish hide in rocks and sand to catch prey, some paralyze other fishes or some other ocean animal for safety and food, some fish like remora attach to larger fishes like sharks for protection and food.
2. Animals from the desert adapt to the hot desert environment by only coming out at night while hiding in burrows during the day. Some desert animals like kangaroo rats can survive their whole lives without drinking water as they obtain all the moisture they need from the food in their diets.
3. Antarctica is found in the world's coldest region, the South pole. Animals found in this region show various adaptations in order to survive the extreme cold conditions. Antarctic animals have unique behavioural adaptations that help them survive the harsh winter. Emperor penguins found in Antarctica form large, ever-moving huddles that allow them to share body warmth, and shelters them from the cold wind.
4. The rainforests are known for plenty of rainfall, abundance of animal and plant life. Due to these unique characteristics of the rainforests, animals have learnt to survive due to the competition for food and abundance of predators. The sloth, an animal found in treetops uses camouflage and moves very slowly to make it difficult for predators to spot.

As the carbon moves around from sink to sink, what are some effects that could result?
The effects of carbon moving from sink to sink is that there is decrease of carbon in the atmosphere.
Carbon sinks and it's effects to the atmosphereCarbon is one of the atmospheric elements that is being recycled in nature through a process called carbon cycle.
Carbon sink is defined as the an environment or an entity that has the ability to absorbs carbon than it can return to the atmosphere. A typical example is the green plants.
These sinks are very important in keeping the levels of carbon dioxide in the atmosphere at manageable level.
Human activity in managing farmland affects the amount of carbon dioxide removed from the atmosphere by plants.
These sinks of carbon dioxide affect the carbon cycle by decreasing the amount of carbon dioxide in the air.
Therefore, the effects of carbon moving from sink to sink is that there is decrease of carbon in the atmosphere.

which two adaptations of herbivorous enables them to digest cellulose
Answer:
Cellulose Digestion in Herbivores
By means of the symbiotic gut bacteria, cellulose can be digested by herbivores with the help of monogastric digestion. Herbivores are less efficient than ruminants in the case of extracting energy from the digestion of cellulose. Here, cellulose is digested by microbial fermentation.
Explanation:
Their molar and premolar teeth help to crush and grind the food and bacteria present in their caecum help in the digestion of cellulose.
How does herbivorous digest cellulose?Cellulose is a polysaccharide made up of repeating glucose units linked by β-1,4-glycosidic bonds, only herbivores are able to digest this biomolecule.
Herbivores have molar and premolar teeth, this flat molars (back teeth) with rough surfaces, which are used for chewing up tough plant tissues. Ruminants have rumen having bacteria which are enabled animals to digest cellulose.
Inside the rumen of cattle, certain bacteria and protozoans are able to secrete the enzymes, which break the cellulose and convert it into glucose units to provide energy.
Therefore, teeth and bacteria two adaptations of herbivorous enable them to digest cellulose.

Which group of organisms can display the most significant adaptations to their environment in the shortest period of time?
A. Bacteria
B. Fish
C. Insects
D. Mammals
Answer:
A. Bacteria
Explanation:
Displayed by how rapidly antibiotic resistance can develop, bacteria are the organisms that can make the quickest, significant adaptations.
Bacteria also reproduce by binary fission, where one bacteria becomes two.
This method of reproduction occurs rapidly, meaning that bacteria grow exponentially, as each bacteria will double. Over time, this will create a huge population.
This ability to reproduce quickly into a large population means that there is a greater chance for diverse mutations to appear. Some of these mutations will be helpful, and allow the bacteria to survive and reproduce when there are changes to their environments.
These mutations will lead to quick adaptations to the environment.
So, the correct answer is A. Bacteria
Bacteria can display the most significant adaptations to their environment in the shortest period of time.
What are bacteria?Bacteria are the species that can make the quickest, most substantial modifications, as demonstrated by how quickly antibiotic resistance can emerge.
Bacteria can also divide in two through a process known as binary fission.
As a result of this quick process of reproduction, bacteria multiply exponentially since each bacterium doubles in size. This will eventually result in a vast population. With such rapid population growth, there is a higher likelihood that different mutations will manifest themselves.
Therefore, Bacteria can display the most significant adaptations to their environment in the shortest period of time.

The amount of energy required to heat 0.5 kilograms of water until the temperature increases 12° C is about
Answer:
Q = 25104 / 4.184 = 6000 Calories or 6 Kcal
Explanation
Energy can be calculated by the equation
Q = m x Cp x delta T
where
m = mass = 0.5 kg
Cp = specific heat of water = 4184 J
Delta T = 12 degrees
Multiplying all
Q = 0.5 x 4184 x 12 = 25104 Joules
Converting it to Calories
Q = 25104 / 4.184 = 6000 Calories or 6 Kcal
From about 4 billion years ago to about 2.5 billion years ago, oxygen gas became more common in Earth's atmosphere. Oxygen was a toxic compound to most life forms from that time period. Today, oxygen is required by all but some of the most primitive life forms. Which statement best explains how early life forms that were harmed by oxygen evolved into today's life forms that require it?
Warming temperatures allowed the colonization of land environments, where oxygen was more plentiful.
Carbon dioxide-using species all became extinct, which allowed oxygen-using life forms to flourish in shallow oceans.
Over time, many species gradually adapted to a more oxygen-rich environment, allowing them to survive in shallow water and on land.
The growth of seas allowed early species to survive by using dissolved carbon dioxide in seawater rather than using it directly from the air.
Answer:
Over time, many species gradually adapted to a more oxygen-rich enviroment, allowing them to survive in shallow water and on land.
