1. Science is the greatest collective endeavor. It contributes to ensuring a longer and healthier life, monitors our health, provides medicine to cure our diseases, alleviates aches and pains, helps us to provide water for our basic needs – including our food, provides energy and makes life more fun, including sports, music, entertainment and the latest communication technology. Last but not least, it nourishes our spirit.
2. Science generates solutions for everyday life and helps us to answer the great mysteries of the universe. In other words, science is one of the most important channels of knowledge. It has a specific role, as well as a variety of functions for the benefit of our society: creating new knowledge, improving education, and increasing the quality of our lives.
3. Science must respond to societal needs and global challenges. Public understanding and engagement with science, and citizen participation including through the popularization of science are essential to equip citizens to make informed personal and professional choices. Governments need to make decisions based on quality scientific information on issues such as health and agriculture, and parliaments need to legislate on societal issues which necessitate the latest scientific knowledge. National governments need to understand the science behind major global challenges such as climate change, ocean health, biodiversity loss and freshwater security.
4. To face sustainable development challenges, governments and citizens alike must understand the language of science and must become scientifically literate. On the other hand, scientists must understand the problems policy-makers face and endeavor to make the results of their research relevant and comprehensible to society.
5. Challenges today cut across the traditional boundaries of disciplines and stretch across the lifecycle of innovation -- from research to knowledge development and its application. Science, technology and innovation must drive our pursuit of more equitable and sustainable development.

explain why antibiotics are not consistently effective against infection of bacteria
Explanation:
Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.

Answer:
Statements thar are true:
Some organisms have phenotypes that make them better increase chances of reproduction.
Natural selection continues to occur even today
Phenotypes found In the most successful members of a species become the most prevalent after several generations.
Explanation:
It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.
Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.
Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.
A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.

What would happen to the DNA molecule if the pairing was non-complementary, in other words, the two purines (adenine and guanine) paired with one another and likewise the two pyrimidines (thymine and cytosine) paired with each other.
If the base-pairing in DNA becomes non-complementary such that purine bases can pair with one another and pyrimidine bases can pair with one another, the 1:1 ratio of purine to pyrimidine bases in DNA will no longer hold.
Due to the complementary base-pairing rule, the ratio of purine to pyrimidine bases in DNAs is usually 1:1. This is because Adenine always pairs with Thymine while Guanine always pairs with Cytosine.
Once this base-pairing rule is removed and becomes purine-purine and pyrimidine-pyrimidine pairings, then it becomes unnecessary for the ratio of purine to pyrimidine bases to be 1:1.

If you found a white sheep and wanted to determine its genotype, with what kind of animal would you cross it
The ideal would be to cross this sheep with several black sheep and observe the color of each offspring.
We can arrive at this answer because:
When crossing white sheep with black sheep it is possible to observe the genotypes of the offspring to determine the genotype of the white sheep.This will be even more efficient if we know the genotype of the black sheep.In this case, if the crossing of the white sheep with the black sheep generates an offspring with all individuals with black fur, we can determine that the white sheep has the h0m0zygous recessive genotype.If the offspring is composed entirely of individuals with white fur, we can state that the white sheep has the dominant h0m0zygous genotype.If the offspring have most of their members with white fur and a small amount with black fur, it means that the white sheep has a heterozygous genotype.In this case, the observation of the offspring's fur is essential to determine the genotype of the white sheep.

la respiration cellulaire aérobie, l'oxygène gazeux est combiné avec
des molécules alimentaires où
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.

An individual with androgen insensitivity syndrome will:
A. Not be feminized at puberty
B. Prefer a female sexual partner
C. Not function sexually as an adult
D. Have female external genitalia
Answer:
D I think. i am not completely sure.
An individual with androgen insensitivity syndrome will have female external genitalia, which is option D, as androgen insensitivity syndrome (AIS) is a genetic condition in which an individual's cells are unable to respond to androgens.
What is androgen insensitivity syndrome?Androgen insensitivity syndrome (AIS) is a genetic disorder in which an individual's body is unable to respond properly to male sex hormones, called androgens. The condition is caused by mutations in the gene that codes for the androgen receptor, which is a protein that binds to androgens and enables them to activate certain genes. In individuals with AIS, the androgen receptor either doesn't work at all or doesn't work properly, which leads to a range of physical changes that can vary in severity depending on the degree of androgen insensitivity.
Hence, An individual with androgen insensitivity syndrome will have female external genitalia, which is option D.
