If 22% of a DNA sample is made up of cytosine, C, what percentage of the sample is made up of adenine,
A?
Answer:
28% of Adenine
Explanation:
Chargaff's Rule states that A = T and C = G
Because of that, the sample must have the equation:
A + C = T + G
G must have the same amount as C so,
A + .22 = T + .22
Both sides of the equation must equal each other by .50, so .50 - .22 = .28
.28 x 100 = 28%
If 22% of a DNA sample is made up of cytosine, C, the percentage of the sample is made up of adenine, A is 28%
What is DNA?The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.

1.What is budding
2.What is vegetative propagation
[tex]\huge\underline\bold\blue{ƛƝƧƜЄƦ}[/tex]
Budding - It is a type of asexual reproduction where in a daughter organism is formed from a small projection known as bud. it develops as an outgrowth due to the repeated cell division on the parent body. when fully grown it detects to grow into a new independent individual
For.eg. hydra
Vegetative Propagation - it is a type of axle plant reproduction in which new plans are obtained from a part of the parent plant. under favorable conditions various touch to take part in the type of reproduction.this is known as natural vegetative propagation where plants parts like root stem and leaves develop into new plants
the property of vegetative propagation is used in cutting tearing and grafting these are known as the method of artificial vegetative propagation. they are used for many plants like sugarcane , rose, etc

La principal función del aparato respiratorio es inhalar oxígeno y eliminar dióxido de carbono. El oxígeno inhalado penetra en los pulmones y alcanza los alvéolos. Las capas de células que revisten los alvéolos y los capilares circundantes se disponen ocupando el espesor de una sola célula y están en contacto estrecho unas con otras. Esta barrera entre el aire y la sangre tiene un grosor aproximado de una micra (1/10 000 cm). El oxígeno atraviesa rápidamente esta barrera aire–sangre y llega hasta la sangre que circula por los capilares. Igualmente, el dióxido de carbono pasa de la sangre al interior de los alvéolos, desde donde es exhalado al exterior.
La sangre oxigenada circula desde los pulmones por las venas pulmonares y, al llegar al lado izquierdo del corazón, es bombeada hacia el resto del organismo (véase Función del corazón). La sangre con déficit de oxígeno y cargada de dióxido de carbono vuelve al lado derecho del corazón a través de dos grandes venas: la vena cava inferior y la vena cava superior. A continuación, la sangre es impulsada a través de la arteria pulmonar hacia los pulmones, donde recoge el oxígeno y libera el dióxido de carbono.
Intercambio de gases entre las alveolas y los capilares
Para mantener la absorción de oxígeno y la emisión de dióxido de carbono, entran y salen de los pulmones entre 5 y 8 L de aire por minuto, y cada minuto se transfiere alrededor del 30% de cada litro (cerca de tres décimos de galón) de oxígeno desde los alvéolos hasta la sangre, aun cuando la persona esté en reposo. Al mismo tiempo, un volumen similar de dióxido de carbono pasa de la sangre a los alvéolos y es exhalado. Durante el ejercicio, es posible respirar más de 100 L de aire por minuto y extraer de este aire 3 L de oxígeno por minuto. La velocidad de entrada del oxígeno en el organismo es una medida importante de la cantidad total de energía consumida por este. La inspiración y la espiración se llevan a cabo gracias a los músculos respiratorios.

Which of the following is not a principle of natural selection?
Answer: The last one on the bottom i'm in biology
The statement which is not a principle of natural selection is, in every population, adaptations allow some organisms to survive and reproduce better than others. So, the correct option is D.
What do you mean by Natural selection?Natural selection is the process through which populations of living organisms adapt and change their needs as per nature.
The given statement gives the idea of adaptation rather than natural selection. Natural selection gives the idea of competing for limited resources. Natural selection always leads to the most favorable types of variation that an individual possess.
Therefore, the statement which is not a principle of natural selection is, in every population, adaptations allow some organisms to survive and reproduce better than others.

what stores and delivers nutrients throughout the cell and transports waste to the cell membrane
[tex] \huge \sf \star{Answer} \star[/tex]
Vacuoles store water, food, and waste. The endoplasmic reticulum (ER) is a series of tunnels throughout the cytoplasm. They transport proteins from one part of the cell to another. Ribosomes are the protein factories of the cell.
Hope it helps uh...The organelle that is responsible for storing and transporting nutrients through the cells is Vacuoles.
Vacuoles are also know as storage containers, they act as a storage organ in the body. This storage organ helps to transport food substances /molecules in the cell. Vacuoles are composed of enzymes, they help to hold water an food molecules. Vacuoles also help to remove waste substances that are harmful to the body.
The vacuole helps to keep balance in the body as they help to keep useful molecules and also get rid of waste substances.

First question: When the population of lynx increases, the population of hares will decrease due to being over-hunted by more predators than usual. The hare is a source of food to the lynx, so with more lynx's...less hares... and less hares means either less food for the lynx and their population starts to die off...OR... The lynx adapt and start hunting new animals which could cause a massive disruption in the food chain.
Second question: When the number of hares increase in the environment it would mean more food for the lynx and other predatory animals. But with more food, comes more overpopulation. with plenty to eat the lynx population increases and that could cause problems for the environment, and other creatures.

What is the normal pathway a cell uses to make and release proteins?
ribosome -> ER -> Golgi -> released
lysosome -> Golgi -> ER -> released
ribosome -> Golgi -> ER -> released
ribosome ->lysosome -> ER -> released
Answer:
ribosome -> ER -> Golgi -> released
Explanation:
Ribosomes are where proteins are created, ribosomes are located on the rough endoplasmic reticulum (RER). From the ER, proteins will be transported to the Golgi Complex for packaging, transport, and release. The answers with lysosome can be ignored because lysosomes break down waste materials of the cell. Therefore the answer is ribosome -> ER -> Golgi -> released.
