Thermoregulation. The integumentary system keeps body temperature within limits even when environmental temperature varies; this is called thermoregulation.
in an ecosystem, lion eat gazelles and gazelle eat wild grasses. What happen if the population of lion is decline?
Answer: gazelle populaton would increase, and wild grasses would decrease
Explanation: becuase lions are decreasing, less and less gazelles are being eating, giving room for more gazelles to be born, increasing their population, and beause there are more gazelles, they are eating more and more grass, deacreasing the grass.

differentiate between circadian rhythms which are entrained and circadian rhythms which are free-running.
Answer:
Free-running rhythms are characterized by a consistent delay in the timing of the circadian cycle by as much as 60 to 70 minutes per day and can be detected by measurement at regular intervals of a marker rhythm, such as the daily rise in the plasma melatonin concentration.

how changes in the atmosphere effect to the plants growth?
Answer:
Mark brainliest please!
Explanation:
Climate change affects the growth of plants in many ways but as we know its 3. The first, as CO2 levels increase, plants don't need a lot of water to do photosynthesis. Scientist have now discovered a third effect: As CO2 levels go up higher, it amps up photosynthesis. Plants in more of this heat, CO2-rich environment grow bigger and better, with more plant like leaves and such.

Which statement describes how humans can decrease an ecosystem's ability to support life?
A. People cut down the trees in a forest, leaving less habitat for squirrels.
B. People build and put up bird houses, giving bluebirds needed nesting space.
O C. People allow small fires to burn in a grassland, returning nutrients to the soil.
D. People remove non-native species from a lake, allowing other plants to grow.
Answer:
A. People cut down the trees in a forest, leaving less habitat for squirrels.
Explanation:
A large percentage of the depletion of an ecosystem can be attributed to anthropogenic or human activities. Ecosystems are naturally known to support or inhabit life. For example, many trees in an ecosystem are homes to living organisms such as birds, insects, snakes etc.
However, according to this question, an exemplary description of how humans can decrease an ecosystem's ability to support life is when "people cut down the trees in a forest, leaving less habitat for squirrels". This act will decrease the forest's ability to support life.

how are fungal cells different from plant and animal cells?
Answer:
Fungus, A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, those being Plantae, Animalia, Protozoa, and Chromista.
Explanation:
Fungi and animals are very different from each other and classified as completely separate kingdoms. At the cellular level, both animals and fungi are composed of eukaryotic cells. Fungal cells differ from plant cells in that they do not have chloroplasts and cannot carry out photosynthesis to make their own food.
The_____hypothesis states that selection favored skin in populations under conditions of high uv radiation (environmental stressor) because those individuals were protected against the consequences of_____destruction and were more likely to have children who could reproduce. Unlike the hypothesis, the folate hypothesis involves as a result of natural selection.
Answer:
Folate
Dark
Folate
Explanation:
As per the Folate hypothesis of Vitamin D, the photosensitive vitamins are protected by the two clines of skin pigmentation. These clines of skin pigmentation maintain vitamin D level and folate which is essential for the preservation of the reproductive health

disturbance destroying an area through the climax of ecological succession
Answer:
hope this helps
secondary succession
Explanation:
Large, low intensity disturbances, such as plowing in conventional agriculture, result in moderate amounts of succession, where species can survive in the soil and quickly recolonize areas after a disturbance. This type of succession is often called secondary succession

Select ALL of the abiotic factors
lesson 5.01
Question 1 options:
fungi
air
soil
light
salinity
Answer:
light
Explanation:
An abiotic factor is a non-living component in the environment. This can be either a chemical or physical presence. Abiotic factors fall into three basic categories: climatic, edaphic and social. Climatic factors include humidity, sunlight and factors involving the climate. Edaphic refers to soil conditions, so edaphic abiotic factors include soil and geography of the land. Social factors include how the land is being used and water resources in the area. Five common abiotic factors are atmosphere, chemical elements, sunlight/temperature, wind and water.
Temperature and Light

•••
Temperature of the air and water affect animals, plants and humans in ecosystems. A rise in temperature has the potential to change the way a living thing develops, because it changes the metabolic rate of the organism. All living organisms have a tolerance level for temperature range. For example, a human being would die if he stood out in minus 50 degree temperatures for any length of time. Light exposure often affects the temperature. Areas with direct sunlight are warmer

How is a whale more like a human than a fish? CHOOSE ALL THAT APPLY 1.warm blooded 2.breast feeds its young 3.spends much time out of the water 4.can hold its breath for long periods of time
Answer:
1. warm blooded, 2. breast feed its young
Explanation:
Whales are warm blooded, which means they keep a high body temperature that does not change in the cold water. Fish are cold-blooded, so their body temperature changes depending on the temperature of their environment. AND hales are other mammals that feed their young milk too, although it takes plenty more to feed them than human babies
