Homeostasis is the body’s ability to maintain a stable internal environment when faced with a changing external environment. Group of answer choices True False.
Homeostasis is the ability of the body to preserve a steady inner environment when encountered with a changing outer condition. The statement is true.
What is homeostasis?The condition of the constant inner environment in the body of the living organism is balanced by the process of homeostasis. It is necessary for regular body functioning.
Homeostasis is affected by many factors like water, food, pH, temperatures etc. the level of these factors are necessary to be maintained to keep the organism fit and healthy.
It is maintained by the feedback regulations and is the response to the outer varying environment. The negative feedback maintains the response to the outer changing stimuli.
Therefore, the statement is true.

not compatible with the antigens on the blood.
Answer: Antigens on the blood determine a person's blood type. Antibodies in the blood attack foreign blood not compatible with the antigens on the blood. Still stuck?
Explanation:
Blood type is determined by the presence or absence of specific antigens on the surface of red blood cells.
What is blood type?The presence or absence of certain antigens on the surface of red blood cells is described by blood type, which is a classification system.
The presence or absence of two types of antigens, A and B, determines the four major blood types: A, B, AB, and O.
The presence or absence of specific antigens on the surface of red blood cells determines blood type.
To avoid a potentially fatal reaction during a blood transfusion, it is critical to match the recipient's blood type with that of the donor.
When a person receives blood that does not match their blood type, their immune system may recognise the foreign blood cells as invaders and mount an immune response.
Therefore, blood type matching is essential to ensure the safety and effectiveness of blood transfusions.

As citizen- scientists, what factors would you include in your letter to help educate people, including other citizen-scientists, about the importance of preserving biodiversity? thank you for whoever answers!!
Answer:
The factors I would include in my letter to help educate people is that in the niche diversity, a niche could be shared by two different species so they would compete for resources. If they are low, then one species may die out. The importance of preserving biodiversity is because of the natural resources which are often at the root of conflict.

Explanation:
and the reason i think this

neither is #2 so yea
1 and 2 are formed by underground reactions between acid in groundwater and limestone. So, the correct option is (A).
What is Groundwater?Groundwater is defined as the water which exists below the Earth's surface in the pores of rock and soil and in the fractures of rock formations. Available freshwater in the world is groundwater is about 30 percent. A unit of rock in the form of unconsolidated deposit is called an aquifer when it can produce useful quantities of water.
It is the underground water present in the saturated zones below the surface of the land. Groundwater does not form underground "rivers". But since it fills the pores and fractures in underground materials such as sand, gravel and other rock.
The upper layers of soil above the groundwater contain carbon and limestone. The water combined with the carbon becomes acidic which destroys the limestone resulting in the formation of sinkholes and caves.
Thus, 1 and 2 are formed by underground reactions between acid in groundwater and limestone. So, the correct option is (A).

List 5 reasons the wolf makes Yellowstone worse.....
Why are elk healthier if the top predator; the wolf, is healthy and hunting them?
Who is at the top of the food chain in Yellowstone.
Answer:
Temperate Zone Ecosystem
Explanation:
Yellowstone National Park has one of the largest temperate-zone ecosystems. Not to mention there is tons of diversity within the park from the wildlife, to the vegetation, and the lakes.
5 reasons why wolves make Yellowstone better:
1. Rebalanced elk & deer populations
2. Return of certain species: songbirds, beavers, eagles, & foxes
3. Vegetation species like aspen trees made a return
4. Enhanced tourism opportunities
5. They help to redistribute nutrients and provide food for other wildlife species
5 reasons why wolves make Yellowstone worse:
1. Decline of the elk herd that lives in the Northern range
2. Changed animal behaviors (mainly elk)
3. Attacking livestock & affecting ranchers
4. Reduced hunting opportunities
5. Pose a possible threat to tourists & pets
Elk are healthier because wolves prey on the sick and wounded elk since they are easy to attack. Wolves ruling out the sick elk help the herds by preventing any sicknesses/diseases. When elk aren't being hunted they spend most of their time feasting away which has negatively impacted vegetation and it can also hurt them (overeating). Now that wolves hunt them, they no longer overeat.
Wolves and bears are at the top of the food chain in Yellowstone. They prey on elk and bison as their main source of food.

Fruits and stem have lenticels. Give reason
Answer:
because lenticels permit the exchange of gases between the environment and the internal tissue spaces of the organs
Fruits and stems have lenticels. These are the specialized cells which permit the exchange of gases between the atmosphere and the plant body.
What are lenticels?A lenticel is a specialized tissue which is a porous tissue. It consist of cells with very large intercellular spaces in the periderm of the secondarily thickened organs in the plant body and the bark of the woody stems and roots of the dicotyledonous flowering plants.
Lenticels can be easily seen as they are visible on the surface of fruits, such as mango, apple, and avocado. Lenticels permit the exchange of gases between the external environment and the internal tissue spaces of the organs such as stems and some fruits of the plant body. These cells permit the entrance of oxygen gas into the plant and simultaneously the output of carbon dioxide and water vapor from it.
