All organisms have adaptations for their environment. Identify two adaptations that could be useful for organisms that live in a desert biome but not in a tundra biome. Explain your reasoning.
Answers
Answer:
1) The ability to burrow under sand to protect themselves from heat
2) Adaptations to conserve water
Explanation:
Many animals have adapted to dessert biomes by burrowing under the sand to protect themselves from the heat. This ability would be useless in a tundra biome because it is very cold. To maintain homeostasis animals in the tundra biome often have thicker fur to keep themselves warm.
Another adaptation in the dessert biome is to conserve water. Plants and animals such as camels have structures to help them conserve water. For example a cactus stores the water from rain in its stem and a camel is able to save water in their hump. There are very little plants in the tundra biome, but this adaptation would be unnecessary for them.

Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.
How can the presence of one species in the same ecosystem assist another?A mutualism occurs when two species have a long-term relationship that benefits both of them (+/+ interaction). Some fungi, for example, create mutualistic relationships with plant roots. The plant may photosynthesize and gives fixed carbon to the fungus in the form of sugars and other organic compounds.
The presence of several species in an ecosystem balances it. The species in an ecosystem interact with one another in some way. For example, the existence of a plant species will offer food for the numerous herbivores found in an ecosystem. A predator may consume a variety of prey. As a result, the existence of diverse prey reduces the likelihood of a species becoming extinct in the ecosystem. As a result, all creatures in an ecosystem are dependent on one another in some way.

Heavy growth in the incubator after bacterial strains were incubated in candle and anaerobic jars
Answers
Answer:
Heavy growth in the incubator refers to the significant increase in the number of bacteria that were being cultured or grown in a controlled environment. The incubator refers to the device that provides the optimal conditions, such as temperature and humidity, for the growth of microorganisms.
Explanation:
When bacterial strains were incubated in candle and anaerobic jars, it means that the bacteria were placed in two different environments to observe their growth. The candle jar is used to create a low-oxygen environment, while the anaerobic jar creates a completely oxygen-free environment. The fact that there was heavy growth observed indicates that the bacteria thrived and multiplied rapidly in both the candle jar and anaerobic jar. This means that the bacterial strains were able to adapt and survive in low-oxygen or oxygen-free conditions. Overall, the observation of heavy growth in the incubator after incubating the bacterial strains in candle and anaerobic jars highlights the ability of these bacteria to flourish in specific environments with limited or no oxygen availability.
Answer the following questions: 1) Tell the pathway of the blood from the time it first enters the heart until it leaves to go back out to the body. Be sure to include where it picks up oxygen :) 2) Briefly tell how the circulatory system and respiratory system work together. 3) Do you know what blood type you are?
Answers
Answer:
1) The pathway of blood starts when it enters the heart through the superior and inferior vena cava, which carry deoxygenated blood from the body. The blood then enters the right atrium, passes through the tricuspid valve, and enters the right ventricle. From the right ventricle, it is pumped through the pulmonary valve into the pulmonary artery, which carries the blood to the lungs. In the lungs, the blood picks up oxygen through the process of oxygenation. Oxygenated blood then returns to the heart through the pulmonary veins, entering the left atrium. It passes through the mitral valve into the left ventricle and is then pumped out of the heart through the aortic valve into the aorta. The aorta distributes the oxygenated blood to the rest of the body.
2) The circulatory system and respiratory system work together to ensure the exchange of oxygen and carbon dioxide between the body and the environment. The respiratory system, consisting of the lungs and airways, is responsible for the inhalation of oxygen and the exhalation of carbon dioxide. Oxygen enters the bloodstream through the alveoli in the lungs, where it binds to red blood cells. The circulatory system, specifically the cardiovascular system, then transports oxygenated blood to the body's tissues and organs. In return, deoxygenated blood carrying carbon dioxide is returned to the lungs to be exhaled. This continuous cycle ensures that oxygen is supplied to the body's cells and waste carbon dioxide is removed.

Highly sensitive cells within the hypothalamus that react to changes in blood composition and cause the release of antidiuretic hormone (ADH) when appropriate are called.
Answers
Answer:
osmoreceptors
Explanation:
Osmoreceptors are nerve cells (neurons) capable of detecting changes in the extracellular fluid (ECF) osmolality, i.e., in the amount of solute in free water within the ECF. Osmoreceptors are known to contribute to osmoregulation by controlling body-fluid balance. These sensory receptors are mainly localized in the hypothalamus of homeothermic animals where they detect variations in the osmotic pressure and stimulate the release of antidiuretic hormone (ADH) in blood in response to the increase in plasma osmolality.
