Given what we know about the protein composition of hair, the protein in shampoo cannot replace the protein in damaged hair due to the fact that it would not be giving the cells the raw material needed to create the protein.

In the human body, along with all other living things, proteins are created from amino acids. The genetic code is read using a strand of messenger RNA called mRNA. Then, a transfer version of this known as tRNA brings the corresponding amino acid based on the genetic code found in the message. These amino acids are then chained together to form proteins.

The protein in shampoo cannot replace the protein in damaged hair because cells do not use entire proteins as a substrate, they use amino acids to create proteins. This may seem counterintuitive, but there are very good biological mechanisms behind it. In order for a shampoo to fix damaged hair, it must contain the amino acids necessary to re-create the lost proteins.

There are no PHOTORECEPTORS in the OPTIC DISC located where the nerve fibers of the RETINA leave the eye and enter the OPTIC NERVE. This region is commonly called the BLIND SPOT.

The retina is an important layer of nervous tissue that covers the inside of the eye, in which the sensation of vision initiates.

Photoreceptors are specialized cells within the retina that respond to light stimuli. In the retina, there are two types of photoreceptor cells: cones and rods.

The blind spot is a small portion of the visual field of the eye that localizes in the optic disk within the retina.

There are no rods or cones (i.e. photoreceptor cells) within the optic disk.

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.

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.

Answer:

Photosynthesis converts carbon dioxide and water into oxygen and glucose.

Explanation:

Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Answer:

Scientists show evidence that nitrogen acquired during Earth's formation came from both the inner and outer regions of the protoplanetary disk. Nitrogen is a volatile element that, like carbon, hydrogen and oxygen. Nitrogen makes up 78 per cent of the air we breathe, and it's thought that most of it was initially trapped in the chunks of primordial rubble that formed the Earth. When they smashed together, they coalesced and their nitrogen content has been seeping out along the molten cracks in the planet's crust ever since.

The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.

Answer:

Water helps in the germination of seeds. (ii) Water helps in the process of photosynthesis by which plants prepare their food. (iii) water helps in the transport of nutrients and minerals from soil to the plant

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.

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.

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.
