PLEASE HELP THEIR JUST TWO SMALL QUESTIONS!!!!!
Vsevolod [243]

Answer:

I did some research for you and I found this. I hope it helps you.

Explanation:

"Continental drift and sea-floor spreading became widely accepted around 1965 as more and more geologists started thinking in these terms. By the end of 1967, Earth’s surface had been mapped into a series of plates (Figure 10.16). The major plates are Eurasia, Pacific, India, Australia, North America, South America, Africa, and Antarctic. There are also numerous small plates (e.g., Juan de Fuca, Nazca, Scotia, Philippine, Caribbean), and many very small plates or sub-plates. For example the Juan de Fuca Plate is actually three separate plates (Gorda, Juan de Fuca, and Explorer) that all move in the same general direction but at slightly different rates."

Do you agree with Dr. Walker and his colleagues that the changes to Jordan Jones’s meal could not explain his improved performan
MatroZZZ [7]

Answer: I agree with Dr. Walker and his colleagues that the changes to Jordan Jones’s meal could not explain his improved performance.

Explanation:  I agree with Dr. Walker and his colleagues that the changes to Jordan Jones’s meal could not explain his improved performance because, food can´t change anything except for your hungriness, and the more food you eat the more fat you get, and not slim.

Give 5 examples each of mutualism, communalism, and parasitism.
lys-0071 [83]
<span>1. Mutualism is a type of relationship that can be seen between two individuals of two different species to obtain benefits for both of individuals.

Examples : Coral polyps and zooxanthellae
                   bee and flower
                   Lichens
                   Rhizobium and root nodules
                   Ungulates and bacteria which live in their intestines

</span><span>2. Commensalism (this is the correct word) is a type of relationship between two organisms which belonged to two different species that one individual obtains benefits while other doesn't have any harm or benefit.

Examples : Remora and sharks
                   Orchids and trees
                   Pseudoscorpions and Beetles
                   Cattle Egrets and Livestock
                   hermit crab and sea anemone
</span>
3. Parasitism is a relationship between two organisms of two different species where one individual (parasite) gets benefits by harming other individual (host).
 
Examples : <em>Cuscuta</em> (parasite)<span> and angiosperms (host)
                    Parasitic viruses (parasite) and human (host)
                    Tape worms (parasite) and pigs (host)
                    Flukes (parasite) and human (host)
                    Parasitic bacteria (parasite) and human (host)</span>

Describe how energy and matter move through the environment under both aerobic and anaerobic conditions.
elixir [45]

<span>1.    </span>Describe how energy and matter move through the environment under <span>
A. Aerobic conditions -Photosynthesis and Respiration
-After photosynthesis occurs, the plant enters the carbon cycle. The carbon cycle uses the by-product of photosynthesis which is carbon dioxide. Carbon dioxide combined with water yields glucose (used as food) and oxygen that is released back into the atmosphere. During photosynthesis, respiration occurs which uses the oxygen and glucose to yield carbon dioxide and water which starts the carbon cycle.

B. Anaerobic conditions Muscle respiration 
-This process does not require the use of oxygen.
Glucose stored in the body is used during muscle respiration to produce lactic acid and energy that is used for movement. </span>

<span>2.    </span><span> What is chemosynthesis?</span><span>
<span>- Chemosynthesis relies on chemical reactions to produce food. Inorganic compounds such as hydrogen sulfide, carbon dioxide, and oxygen enter into a chemical reaction that yields sugar, sulfur, and water, Chemosynthesis occurs most commonly in deep-sea ecosystems where the sun cannot penetrate. </span></span>

<span>3.    </span>How do chemosynthetic organisms get energy?

<span>-      </span><span>Chemosynthetic organisms make use of chemicals found on the seafloor or on the sea environment. They convert these chemicals through a reaction that yields glucose (which the plants use for food) and sulfur as by-products. In turn, other organisms will use the sulfur by-product to initiate another chemosynthetic reaction to create food.</span>

timofeeve [1]

In order to test the implications of early emotional bonding, scientists have done testing on infant emotionality by separating animal babies from their natural mothers, allowing them to be raised by another of their same species. This testing strategy is called Cross fostering

  • Transfer of children between mothers is known as cross-fostering. This method is used to distinguish between environmental and genetic impacts on behavior.
  • Transferring some freshly born or hatched young of species A from their mother nest to the nests of species B is the primary process of cross-fostering.
  • A behavior can be proven to have a genetic foundation if cross-fostered offspring have a behavioral attribute that is distinct from that of their foster parents and similar to that of their biological parents.
  • Similarly, environmental variables are proven to be dominating if the offspring exhibits qualities that are different from those of their biological parents and comparable to those of their foster parents.
  • There is frequently a combination of the two, demonstrating both genes.
  • This can be utilized in selective livestock breeding to combine desirable genetic traits like weight, fat distribution, or looks with ones that are influenced by the environment, like temper.
