This model chose to include certain features and exclude other features. For example, this simulation only includes rabbits, wolves, and grass but there are other predators of rabbits and other food sources for rabbits. Why do you think the creators focused on these data elements and not others
Answers
The creator focused on these data elements and not others because he was trying to create a food chain instead of a food web.
In the ecosystem, the living and non-living things interact over time leading to exchange of energy.
A food chain can be defined as the steps through which energy transfer occurs in an ecosystem.
The energy flows from the producers (grass), primary consumers, (rabbits) and then the secondary consumers (wolves).
The energy flow is indicated with an arrow thus,
grass ---> rabbit -----> wolves.
Food chain, therefore includes linear sequence of organisms.
Food web on the other hand illustrates a complex feeding relationship within the ecosystem.
The food web is made up of a prey that can be eaten by more than one predator.
Therefore, even though there where other predators of rabbits and other food sources for rabbits, he chose only few features to create a food chain.

Answers
Normally, more than 99% of the sodium filtered at the glomerulus is returned to the blood. Most of this sodium is reabsorbed at the proximal tubule.
The glomerulus are enveloped networks of capillaries found in the nephron of the kidney.The glomerulus are responsible for filtering and purifying blood plasma (such as sodium, phosphorus and potassium).The efferent arteriole emerges from each glomerulus, from which arises a network of peritubular capillaries and descending vasa rectus.Efferent fibers stimulate renin release and proximal tubular sodium reabsorption, thereby affecting renal and systemic vascular resistance.Reabsorption of the initial charge of the main solutes takes place in the proximal tubule.The reabsorption of water throughout the nephron follows the reabsorption of solutes.67% of the filtered water is reabsorbed in the proximal tubule by osmosis, with the reabsorption of sodium coupled to other solutes at this level being the generator of the osmotic gradient.Therefore, we can conclude that the sodium filtered at the glomerulus is returned to the blood. Most of this sodium is reabsorbed at the proximal tubule.

Which selection from the article "Scientists study Persian Gulf reefs for coral survival clues" identifies the biggest threat to coral reefs?
Question 5 options:
Warming waters spark bleaching events. Along with the bleaching, the ocean is becoming more acidic.
The researchers demonstrated that this new organism was the most commonly found algae throughout the gulf's coral reefs. They say it probably adapted as a result of the gulf's harsh conditions.
Answers
Warm and acidic water leads to bleaching of coral reef and the new algae can survive due to mutation in its gene.
The biggest threat to coral reefs in the Persian gulf is the warming of waters due to climatic change as well as acidification of water. Algae present on coral reefs can't tolerate acidic water as well as warm water which leads to the death of algae and the coral looks white or colorless.
A new organism was the most commonly found algae throughout the gulf's coral reefs due to change in the genetic makeup due to harsh climatic conditions so we can conclude that warm and acidic water leads to bleaching of coral reef and the new algae can survive due to mutation in its gene.

Osteoporosis is more prevalent among women than men because women generally
have more bones in their bodies than men have.
take in more calcium than men take in.
have lower bone mass than men have.
exercise more than men do
Answers
Answer:
Have lower bone mass than men have
Explanation:
Osteoporosis is a bone thinning disease that is more prevalent among women than men and typically occurs after 50. The reason women are more likely to get the disease than men is because after 50 many women have gone through or are going through menopause. Menopause causes the ovaries to produce less estrogen which is what had previously been promoting bone density.
The other answers are incorrect because...
A: have more bones in their bodies than men have: for the most part everyone has the same amount of bone in there body (although there are diseases that cause a persons bones to fuse together making them have fewer bones than the average person)
B: take in more calcium then men take in: more calcium would actually cause someone to be less likely to get osteoporosis because it strengthens the bones.
C: exercise more than men do: Osteoporosis is more common in malnourished women and women who do not get regular physical activity to strengthens there bones. So getting more exercise would actually lessen the chance of getting osteoporosis.

Rumen biotechnology improves feed for ruminant animals by boosting the bioavailability of carbohydrates and protein in plants. It can be used to improve the nutritive value of ruminant feedstuffs.
Rumen biotechnology refers to the use and management of the techniques of forestomach fermentation in order to improve the efficiency of ruminant production.
Rumen biotechnology can be used to improve the amount as well as the availability of macronutrients (i.e., carbohydrates and proteins) in plants.
However, this technology (rumen biotechnology) exhibits several limitations mainly associated with the identification of bacterial strains used during inoculation, proteins (recombinant enzymes) and genomic stability of the genetic constructs.

la respiration cellulaire aérobie, l'oxygène gazeux est combiné avec
des molécules alimentaires où
Answers
Answer:
La respiration cellulaire est l'ensemble des processus du métabolisme cellulaire convertissant l'énergie chimique contenue dans le glucose en adénosine triphosphate (ATP). Ces processus impliquent une succession de réactions chimiques formant des voies métaboliques qui appartiennent au catabolisme, c'est-à-dire qu'elles consistent à cliver les grosses molécules biologiques en molécules plus petites, ce qui libère de l'énergie ainsi qu'un certain nombre de déchets. Ces réactions sont globalement exothermiques, c'est-à-dire qu'elles produisent de la chaleur, la plupart étant des réactions d'oxydoréduction. De ce point de vue, la respiration s'apparente chimiquement à une combustion des nutriments, jouant le rôle de donneurs d'électrons (réducteur), en présence d'un accepteur d'électrons (oxydant).
La respiration est l'une des voies essentielles permettant aux cellules de produire de l'énergie métabolique pour leur développement et leur activité. Parmi les nutriments utilisés par les cellules des animaux et des plantes, on compte les glucides (ose), les peptides (acides aminés) et les lipides (acides gras), tandis que l'oxydant le plus fréquent dans les systèmes biologiques est l'oxygène moléculaire O2. L'énergie biochimique récupérée sous forme d'ATP peut ensuite être utilisée par des processus qui consomment de l'énergie tels que les biosynthèses, la locomotion ou encore le transport actif de substances chimiques à travers les membranes biologiques. La respiration aérobie requiert du dioxygène O2 pour produire de l'ATP. C'est la voie prépondérante de dégradation du pyruvate, issu de la glycolyse. Celle-ci se déroule dans le cytosol, mais le pyruvate doit pénétrer dans les mitochondries pour y être entièrement oxydé par le cycle de Krebs, lequel se déroule dans la matrice mitochondriale. Le cycle de Krebs convertit le pyruvate en dioxyde de carbone CO2 et en coenzymes réduites (NADH et FADH2), coenzymes dont les électrons à haut potentiel de transfert contiennent l'essentiel de l'énergie chimique des molécules dégradées. Ces coenzymes réduites sont alors oxydées par la chaîne respiratoire dans la membrane mitochondriale interne. L'énergie des électrons à haut potentiel de transfert permet de pomper des protons hors de la matrice mitochondriale vers l'espace intermembranaire. Il s'établit un gradient de concentration de protons à travers la membrane interne, lequel génère un gradient électrochimique suffisant pour actionner l'ATP synthase, une enzyme capable de phosphoryler l'ADP en ATP grâce à l'énergie emmagasinée dans ce gradient électrochimique. On appelle phosphorylation oxydative l'ensemble formé par la chaîne respiratoire et l'ATP synthase couplés par gradient électrochimique.
Les manuels de biologie indiquent généralement que chaque molécule de glucose entièrement oxydée par la respiration cellulaire est susceptible de produire 38 molécules d'ATP : 2 ATP issus de la glycolyse, 2 ATP issus du cycle de Krebs, et 34 ATP issus de la chaîne respiratoire. Ce rendement nominal n'est cependant jamais atteint en raison des pertes par dissipation du gradient électrochimique à travers la membrane interne des mitochondries ainsi qu'en raison du coût énergétique du transport actif du pyruvate depuis le cytosol jusqu'à la matrice mitochondriale, de sorte que les estimations actuelles s'établissent autour de 30 à 32 molécules d'ATP formées par molécules de glucose oxydée1.
La respiration aérobie est jusqu'à 15 fois plus efficace que la respiration anaérobie, qui produit seulement 2 ATP par molécule de glucose oxydée. Cependant, certains organismes anaérobie, comme les archées méthanogène, sont capables d'accroître ce rendement en utilisant d'autres accepteurs d'électrons finaux que l'oxygène.
Glycolyse
La glycolyse est une voie métabolique qui se déroule dans le cytosol des cellules de pratiquement tous les êtres vivants. Elle peut fonctionner de manière aérobie ou anaérobie, c'est-à-dire respectivement en présence ou en l'absence d'oxygène. Chez l'homme, elle conduit au pyruvate en conditions aérobies et au lactate en conditions anaérobies.
En conditions aérobies, ce processus convertit une molécule de glucose en deux molécules de pyruvate, avec production concomitante de deux molécules d'ATP. Plus précisément, il commence par consommer deux molécules d'ATP pour accroître la réactivité du glucose en vue de son clivage par l'aldolase puis en produit quatre par phosphorylation au niveau du substrat, avec production de deux molécules de NADH. La réaction globale de la glycolyse peut s'écrire :
glucose + 2 NAD+ + 2 Pi + 2 ADP → 2 pyruvate + 2 NADH + 2 ATP + 2 H+ + 2 H2O + chaleur.
