How does earths rotation help to maintain its temperature? Please help!!!
Answers
Answer:
Earth returns an equal amount of energy back to space by reflecting some incoming light and by radiating heat (thermal infrared energy). Earth's average surface temperature is maintained by two large, opposing energy fluxes between the atmosphere and the ground (right)—the greenhouse effect.

Only about 10 percent
of the energy from each
level of an energy
pyramid is available to
the trophic level above
it. (The rest is used to

is lost as heat.)
If the primary producers
have 10,000 units of
stored energy, how
much energy would you
expect to be transfered
to first-level, second-
level, and third-level
consumers?
Answers
Answer:
First leve consumer: 1,000 energy units
Second level consumer: 100 energy units
Third level consumer: 10 energy units
Explanation:
First level consumer: 1,000 energy units. Second level consumer: 100 energy units. Third level consumer: 10 energy units.
What is trophic level?The group of species in an ecosystem that are at the same level in the food chain is referred to as a trophic level. A food chain has five basic trophic levels, each of which has a different nutritional relationship to the main energy source.
The Sun is any ecosystem's main source of energy (although there are exceptions in deep sea ecosystems). Primary producers, sometimes referred to as autotrophs, receive their energy input from the Sun's solar radiation.
The first trophic level is made up of primary producers. Consumers, also known as heterotrophs, make up the remaining trophic levels; heterotrophs are unable to reproduce.
Therefore, First level consumer: 1,000 energy units. Second level consumer: 100 energy units. Third level consumer: 10 energy units.

All of the following are classified as abiotic factors EXCEPT
a pH
b. bacteria
b. salinity
d. oxygen concentration.
Answers
Answer:
In the group of terms, the exception to abiotic factors is bacteria (option b).
Explanation:
Abiotic factors correspond to the elements of an ecosystem that are not considered alive, such as soil, wind, temperature, pH, among others.
All living beings in an ecosystem are biotic elements, including microorganisms such as bacteria. The dynamics of living beings influence the ecosystem, just as abiotic factors influence both the biotic elements and the development of the ecosystem.

What type of clinical diagnosis can be
made by examining a karyotype?
Answers
Answer:
Down syndrome is one (I think)
Explanation:
Clinical cytogeneticists analyze human karyotypes to detect gross genetic changes—anomalies involving several megabases or more of DNA. Karyotypes can reveal changes in chromosome number associated with aneuploid conditions, such as trisomy 21 (Down syndrome).
Karyotyping is the process of pairing and ordering all the chromosomes of an organism, thus providing a genome-wide snapshot of an individual's chromosomes. Karyotypes are prepared using standardized staining procedures that reveal characteristic structural features for each chromosome. Clinical cytogeneticists analyze human karyotypes to detect gross genetic changes—anomalies involving several megabases or more of DNA. Karyotypes can reveal changes in chromosome number associated with aneuploid conditions, such as trisomy 21 (Down syndrome). Careful analysis of karyotypes can also reveal more subtle structural changes, such as chromosomal deletions, duplications, translocations, or inversions. In fact, as medical genetics becomes increasingly integrated with clinical medicine, karyotypes are becoming a source of diagnostic information for specific birth defects, genetic disorders, and even cancers.

13. What term do we use to describe the maintenance of constant conditions, such
as blood glucose levels, body temperature and water levels, inside the body?
A. Hormonal control
B. Nervous system
C. Homeostasis
D. Endocrinosis
Answers
Answer:
C. Homeostasis
Explanation:
"Homeostasis" refers to the process of maintaining the body's equilibrium. The body tries to adjust to different stimuli in order to help it function in normal ranges. For example, when a person is exposed to a cold weather all of a sudden, the person starts to shiver in order to maintain homeostasis. Shivering is a contraction of the muscles that allows the generation of heat.
On the contrary, when a person is exposed to the sun during summer, his body will start to sweat in order to maintain homeostasis. Sweating allows the heat to dissipate from the body thereby lowering the body's temperature.

Food provides molecules that serve as fuel and building material for all organisms. Plants undergo photosynthesis and make their own food. Other organisms, like humans and the horse seen below, are consumers and eat food. How is energy released from food, and what is the importance of ATP? Include the name of the process and the overall chemical equation in your explanation
Answers
Answer:
The correct answer is - cellular respiration is the process to release energy from food in the form of ATP.
Explanation:
Food, as we know, is the only source of energy for the body but it requires to converted from the form of what we eat which is carbohydrates, protein, fat into an energy source that cells and the body can use for various functions. The process that converts food into energy is cellular respiration.
Cellular respiration is a set of complex chemical reactions that convert sugars into energy in the form of ATP which is the only currency of energy cell can use. The reaction has three stages glycolysis converts glucose in pyruvate, Krebs cycle releases carbon in the form of CO2 from pyruvate, and electron transport which is oxygen-dependent reaction.
Cellular respiration can be understood by the following chemical equation:
C6H1206 + 6O2 ====> 6CO2 + 6H2O + ATP

What are Extinct animals?
An extinct animal is an animal which no longer exists. It is completely gone and can no longer be found on the planet Earth. It can be hard to tell exactly when a species, or a specific type of animal has become extinct in nature. Sometimes, scientists think that an animal has disappeared due to changes in the environment, only to find another living animal many years later.
Scientists can determine whether an extinct animal gave birth on land or under water on the basis of position of the head of the fetus.
Therefore, the correct option is C.
