what is Spermatogenesis ?
We run, play, work, study. We need energy to do all of this. In fact, one characteristic of living things is that they need and use energy. Two processes are needed in us humans to break down food to release the energy that is stored in our food. They are ____________ and cellular respiration.
A) circulation
B) digestion
C) excretion
D) photosynthesis
I think digestion would be the answer here. Humans can't do photosynthesis. Excretion is how we expel waste. And circulation is how oxygen gets to our cells.

Scientists have recorded increasing ocean temperatures. Which of the following is not a consequence of these increasing global temperatures?
altered species interactions
lower salinity in ocean water
shifts in the range of habitat for organisms
changes in the seasonal abundance of populations
Answer:
Lower Salinity in the ocean water.
Explanation:
The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
As temperature increases, the space between water molecules increases—also known as density, which therefore decreases. ... Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases
Distinguish between Diet and Nutrition
Answer:
Diet is limiting oneself in foods and calories for several days or weeks. As a result, overweight is rapidly leaving, but once you return to your previous lifestyle, as extra pounds return, and getting rid of them becomes more difficult.
Proper nutrition is a complete balanced everyday diet, in which all necessary products must be present: meat, cereals, dairy products, fruits, vegetables. Eating healthy and balanced all the time not only strengthens the body but also helps to lose weight. It is known that an organism that does not regularly receive all the necessary substances begins to "junk".

[tex]\huge{\mathbb{\tt { What \: is \: Diet?}}}[/tex]
In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons. Although humans are omnivores, each culture and each person holds some food preferences or some food taboos.[tex]\huge{\mathbb{\tt { What \: is \: Nutrition?}}}[/tex]
Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It includes ingestion, absorption, assimilation, biosynthesis, catabolism and excretion. The science that studies the physiological process of nutrition is called nutritional science.[tex]{\boxed{\boxed{\tt { Difference \: between \: Diet \: and \: Nutrition}}}}[/tex]
The main way of getting nutrition is by having a proper diet. Diet comprises of different foods, which contain nutrients. When the foods are ingested, nutrients are absorbed by the body. Body uses them in different metabolic activities. A poor diet will result in a poor metabolic efficiency. Finally, it may lead to nutrient disorders or unbalance nutritional conditions in human body.#CarryOnLearning

31. Which sequence shows increasing ecological
levels of organization?
A. organism, population, community, ecosystem
B. ecosystem, population, organism, community
C. community, ecosystem, population, organism
D. population, organism, ecosystem, community
Hello there, kawissaehsshen!!!
The answer here would be A. The organism is a singular thing, so it should be first. The population comes next - it is all the same type of organism living in one ecosystem. Next is community - this is all the living organisms in the area. Lastly, there is the ecosystem - the organisms, their habitats, and everything else.

A scientist is studying trace fossils of an early mammal. Which type of informatin can be learned from studying
trace fossils?
how many teeth the mammal had
the structure of the mammal's skeleton
information about the behavior of the mammal
how the mammal is related to modern mammals
Answer:
Studying the trace fossils allows scientists to determine how the animal moved, whether it traveled alone or in groups, the environment in which it lived in, an organisms feeding habits or nesting behavior, and their feces, known as profiteroles, can provide information about an organism's diet.
Explanation:
hope it helps
The environment in which the organism lived, its feeding habits or nesting behavior, and their feces, known as profiteroles, can reveal information about an organism's nutrition are all things that can be learned through studying trace fossils.
What types of information do we get from trace fossils?Instead of the preserved remnants of the actual animal's body, trace fossils offer us indirect proof of life in the past in the form of animal footprints, tracks, burrows, borings, and feces.What information can scientists gain from trace fossils?Paleontologists can learn about the activity of ancient species by studying trace fossils. For instance, studying dinosaur footprints has greatly improved our knowledge of their behavior.What are two types of trace fossils?The majority of known trace fossils come from marine strata. There are basically two different kinds of traces: exogenic traces, which are created on the sediment's surface (like tracks), and endogenic traces, which are created within the sediment's layers (such as burrows).

Which best helps scientists determine the age of fossil
Explanation:
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
The method that best helps scientists determine the age of fossils is radiometric dating. This method is highly accurate and reliable, providing precise numerical ages for fossils.
Radiometric dating is a technique that uses the decay of radioactive isotopes to calculate the absolute age of rocks, minerals, and fossils. Different isotopes have specific half-lives, which is the time it takes for half of the radioactive parent isotopes to decay into stable daughter isotopes.
By measuring the ratio of parent isotopes to daughter isotopes in a fossil or rock sample, scientists can determine how many half-lives have passed and calculate the age of the specimen.
This method is highly accurate and reliable, providing precise numerical ages for fossils and other geological materials, and helping scientists understand the timeline of Earth's history and the evolution of life on our planet.
Therefore, The method that best helps scientists determine the age of fossils is radiometric dating.

describe how oxygen and carbon dioxide are cycled using the cardiovascular and respiratory system
Answer:
respiratory system fills the blood with oxygen and gets rid of the carbon dioxide while the cardiovascular system umps the oxygen rich blood all over the body (short answer)
Explanation:
the respiratory system aids in the supply of oxygen to the blood and the exit of carbon dioxide. when the heart takes in blood that is short of oxygen and full of carbon dioxide, the pulmonary arteries pumps the blood to the lungs, who then fill the low oxygen blood with oxygen and transport the carbon dioxide out of the lungs. this oxygen rich blood, which now has a rich amount of hemoglobin, is transported to the heart which is pumped or circulated it to the entire body.

In the carbon cycle, several processes contribute to the movement of carbon through the ecosystem. For each of the types of movement below, name the process in the carbon cycle that accomplishes it: A. Movement of carbon from the atmosphere into living organisms: ___________________ B. Movement of carbon from living organisms into the atmosphere: ___________________ C. Movement of carbon between different organisms due to feeding: ____________________
Answer:
A. Movement of carbon from the atmosphere into living organisms: PHOTOSYNTHESIS
B. Movement of carbon from living organisms into the atmosphere: RESPIRATION.
C. Movement of carbon between different organisms due to feeding: DECOMPOSITION
Explanation:
Carbon is the main element in the compounds that make up living organisms. It is found in the remains of living organisms, fossil fuels, inorganic salts, water bodies and air. It is continuously being removed from and added to the carbondioxide in the atmosphere.
The CARBON CYCLE is defined as the process which brings about the circulation of carbon compounds in nature. These processes include:
--> PHOTOSYNTHESIS: Green plants (producers) are continuously removing carbon dioxide from the atmosphere for photosynthesis. The carbon of the carbon dioxide is incorporated into sugars and other complex organic compounds in plants' tissues. When the plants are eaten by animals (primary consumers), the plant material is digested, absorbed and built up into compounds which form animal tissues. Thus, this accomplishes movement of carbon between different organisms due to feeding.
--> RESPIRATION: Plants and animals respire all the time to obtain energy. During this process, sugar are broken down to liberate carbondioxide and water as wastes. Thus this accomplishes the movement of carbon from living organisms back into the atmosphere.
--> DECOMPOSITION: This is a process in carbon cycle where decomposers feed on the dead and decaying organisms and their excreta and bring about their decomposition. They have enzymes that break down organic compounds into simple inorganic compounds. Although inorganic compounds (carbondioxide) are released during decay, decomposers absorb these compounds for their own use. When decomposers doe, othe decomposers feed on them thereby accomplishing the movement of carbon between different organisms due to feeding.

A balanced polymorphism exists through disruptive selection in ground finches from the Galapagos in which small- and large-billed birds specialize in cracking soft and hard seeds, respectively. If long-term climatic change resulted in all seeds becoming soft, what type of selection would then operate on the finch population?
Answer:
The correct answer is - directional selection.
Explanation:
In a population, if a particular phenotype is favored among all others in every individual by continuously shifting the allele frequency towards one direction only, this type of selection called directional selection. It is a mode of natural selection.
In this case, the finch population will change towards the directional selection due to the food source become similar for both small and large-billed due to climatic change in the long term all seeds become soft so the small billed will be more favored.
Answer:
The correct answer is directional selection.
