Carbon dioxide (CO2) and water (H20) are the molecules used in photosynthesis and rearranged to produce carbohydrates.
WHAT IS PHOTOSYNTHESIS:
Photosynthesis is the process by which green plants manufacture their food (glucose) using energy captured from sunlight. Photosynthesis involves series of biochemical reactions, however, the carbon dioxide and water are the two molecules combined. The general equation is represented as follows:6CO2 + 6H2O → C6H12O6 + 6O2
Therefore, carbon dioxide (CO2) and water (H20) are the molecules used in photosynthesis and rearranged to produce carbohydrates.

What is the function of the interdigital membranes in frogs? Do all frogs posses them? Explain.
Answer:
Function: To improve the animals´ movement and displacement on water.Not all frogs have well-developed membranes. Those with terrestrial habits exhibit reduced interdigital tissue.Explanation:
The interdigital membrane is the skin between the fingers and toes of the animals. This tissue is resistant and flexible. Its expansion varies among species and depends on their habits. The principal function of these membranes is to improve the animals´ movement and displacement on water. This tissue represents a broader area that provides resistance to water so the animal can swim faster and longer. On the ground, these membranes also can be useful while jumping, but this is not its principal function. The development of the interdigital membrane show variation among amphibians. In those taxa that spend most of their time in the water, the membranes are extensive and well-developed. On the contrary, groups that spend most of their lives on the ground, on trees, and other vegetation, exhibit poorly-developed membranes or almost absent.Why are landfill liners NOT a reliable safeguard against aquifer contamination?

How can katey and amanda's amino acid sequence be the same and yet they may have a differences in their DNA?
Answer: Two people can have different DNA sequences but these sequences can code for the same amino acids due to the redundancy of the genetic code in which two different codons can code for the same amino acid.
Explanation:
The genome of an organism is found in a molecule called DNA (deoxyribonucleic acid). The main function of this DNA molecule is the long-term storage of information to build other components of cells, such as proteins and RNA molecules (ribonucleic acid); and the portion of the genome that codes for a protein or RNA is known as a gene. These protein-coding genes are composed of trinucleotide units called codons, each of which codes for an amino acid. For a protein whose sequence is encoded in the nucleotides of DNA to be synthesized, that DNA molecule must first be transcribed into a molecule called messenger RNA, and this molecule is used for a process called translation or protein synthesis. The sequence of the genetic material is composed of four distinct nitrogenous bases, which are represented by letters in the genetic code:
Adenine (A)Thymine (T)Guanine (G) Cytosine (C)Uracil (U) instead of T in RNAThe genetic code is the set of rules that defines how a sequence of nucleotides in RNA is translated into a sequence of amino acids in a protein. This code is common to all living things, which shows that it has had a unique origin and is universal. So, the code defines the relationship between each sequence of three nucleotides (codon) and each amino acid. The number of possible codons is 64, of which 61 code for amino acids (one of them being the start codon, AUG) and the remaining three are stop sites (UAA, UAG, UGA). The codon sequence determines the amino acid sequence in a particular protein, which will have a specific structure and function.
However, the genetic code has redundancy but no ambiguity. For example, two different codon can code for the same amino acid, and the differences between codons encoding the same amino acid have differences in the third position. This is explained by the wobble effect, where the same anticodon (present in the transfer RNA that loads with the amino acid and interacts with the codon in the messenger RNA) can establish interaction with different codons, which differ in their third base. This is why, in general, tolerance to change at this position is greater than at the first and second positions, and therefore tends to be less represented in the case of variations that result in pathologies.
Thus, two people can have different DNA sequences but these sequences can code for the same amino acids due to the redundancy of the genetic code in which two different codons can code for the same amino acid.

Read the excerpt from How Hurricanes Form.
Hurricanes are the largest and most violent storms on Earth. They are large rotating storms with high speeds that form over warm waters. These storms are known as hurricanes in North America and the Caribbean. However, they have different names in other regions. In South East Asia, they are called typhoons. In the Indian Ocean, they are known as cyclones. Hurricane winds move at the speed of at least 74 miles per hour. They can be as wide as 300 miles. But, how are these huge storms formed?
a world map showing that hurricanes occur north of the equator in the Atlantic Ocean, cyclones occur north and south of the equator in the Indian Ocean, and typhoons occur north of the equator in South East asia
Hurricanes are often compared to engines. Just like engines, they need a type of fuel. Hurricanes form over warm ocean waters near the equator. For hurricanes, their fuel is warm, moist air. When hurricanes form, the warm, moist air above the ocean rises upward from close to the surface of the water. Because the warm air rises, it results in less air under the surface of the water. This area with less air is known as an area with low pressure.
Why do some people say that hurricanes are like engines? (2 points)
a
Both hurricanes and engines are loud when they gain power.
b
Both hurricanes and engines can cause serious destruction.
c
Both hurricanes and engines need a fuel to power them.
d

A farmer wanted to test the best way to grow tall lemon trees. Two groups of lemon trees were planted in a grove. One group of lemon trees was watered daily and the other group was watered twice a week.
Answer:
The group of lemon trees that was watered twice a week grow taller.
Explanation:
The group of lemon trees that was watered twice a week grow taller as compared to other group in which lemon trees was watered daily because too wet condition for the lemon tree is bad and can adversely affected its growth and development. Lemon tree needs optimum water for its growth and development. Too much water or drought condition adversely affected the growth of lemon tree which leads to lower height of the lemon tree.
Why is it important for a pregnant woman to know her Rhesus blood type, and the Rh blood type of the father of her baby?
Answer: One of the first tests a pregnant woman should expect is a blood-type test. This test checks her blood type and Rh factor. Her Rh factor may play a role in her baby's health, so it's important to know this information early in pregnancy.
Explanation: if you're Rh negative and your baby is Rh positive, your body might produce proteins called Rh antibodies after exposure to the baby's red blood cells. The antibodies produced aren't a problem during the first pregnancy. The concern is with your next pregnancy.

Eventually, do you think you will the population of the black will decrease and the white increase?
A. Yes
B. No
Answer:
B. No
Explanation:
Projections show that whites will decline; the number of old people will increase; and racial minorities, mainly Hispanics, will grow the most, making them the main engine of demographic change in the U.S. for the next 10 years and beyond.
Today, there are over 74.1 million people under age 18 in the U.S. country. There are 56.4 million people age 65 and older.
Ten years from now, there will almost be as many old folks as there are young ones. The numbers of young people will have grown just a little to 76.3 million, but the numbers of old people will have increased a lot – to 74.1 million. A lot of these new elderly will be baby boomers.

Explain how abiotic factors can have influence on the survival for individuals through natural selection.
Selection: Organisms live within ecosystems, which are made up of various biotic and abiotic factors. These factors contribute to selecting which variations provide the individual with an increased chance of surviving. ... Examples of abiotic factors include temperature, shelter, sunlight, water and nutrients.
Answer:
Biotic and abiotic factors are the environmental conditions that the organisms have to face to live in a specified environment.
Abiotic factors
Abiotic factors are the physical and chemical conditions of an environment. For example : heat, salinity, pressure, light, wind, pH ...
Biotic factors
Biotic factors are all the biological conditions of an environment for a specie/taxa. It can include prey and predator abundance, available food amount, available space, intra and interspecific competition...
The development of organims is under the control of abiotic factors. Some are adapted to heat, cold etc ... The abiotic factors will define which organisms are able or not to live in a specified place.
The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment.
So, the abiotic factors are controling the biotic factors of an environment.

B. VERDADERO.
C. VERDADERO.
D. VERDADERO.
c) D. Contracción de los bronquios.
d) A. Axon, dendritas, cuerpo neuronal.
Explanation:
B) A. FALSO. La médula espinal es una estructura tubular larga y delgada, formada por tejido nervioso, que se extiende desde la médula oblonga del tronco cerebral hasta la región lumbar de la columna vertebral. El cerebro junto con la médula espinal forman el sistema nervioso central, y particularmente la médula espinal es la vía para transmitir los mensajes que envía el cerebro al cuerpo y del cuerpo al cerebro. Entonces no se ocupa de la apreciación de sensaciones.
B. VERDADERO. El cerebelo desempeña un papel importante en el control motor pero también puede estar implicado en algunas funciones cognitivas, como el lenguaje así como en el control emocional, la regulación de las respuestas de miedo y placer,. Aunque sus funciones relacionadas con el movimiento son las más importantes.
C. VERDADERO. El cerebro es la porción mas grande del encéfalo (órgano dentro del cráneo) y está formado por dos hemisferios. También comprende varias estructuras subcorticales, como el hipocampo, los ganglios basales y el bulbo olfativo. Es la región más grande del sistema nervioso central y sus funciones incluyen la iniciación y coordinación del movimiento, tacto, visión, oído, regulación de la temperatura, el razonamiento, las emociones, aprendizaje, etc.
D. VERDADERO. La médula oblonga o bulbo raquídeo es una larga estructura en forma de tallo que constituye la parte inferior del tronco encefálico. Se encarga de conectar al cerebro con la médula espinal, y es responsable de varias funciones del sistema nervioso autónomo que incluyen el control de la ventilación a través de señales procedentes de los cuerpos carotídeos y aórticos como también el control cardiovascular al regular los latidos cardíacos. Aunque también está relacionado con otras funciones tales como la tos, estornudo, reflejos del vómito y la deglución.
c) El sistema nervioso parasimpático (SNP) es una de las tres divisiones del sistema nervioso autónomo, siendo las otras el sistema nervioso simpático y el sistema nervioso entérico. El sistema nervioso autónomo se encarga de regular las acciones inconscientes del cuerpo, en donde el sistema parasimpático es responsable de la estimulación de las actividades de "descanso y digestión" cuando el cuerpo está en reposo, especialmente después de comer. Controla por ejemplo, la salivación, el lagrimeo, la micción, la digestión y la defecación. Su acción se describe como complementaria a la del sistema nervioso simpático, responsable de estimular las actividades asociadas a la respuesta de "lucha o huida". Entonces los procesos que son resultado de la acción del sistema nervioso parasimpático son:
D. Contracción de los bronquios. El SNP controla órganos en situaciones o momentos que requieren una respuesta rápida.
d) Una neurona o célula nerviosa es una célula eléctricamente excitable que se comunica con otras células a través de conexiones especializadas llamadas sinapsis. La misma consta de:
A. Axon (proyección larga y delgada de una célula nerviosa que conduce impulsos eléctricos conocidos como potenciales de acción), dendritas (extensiones protoplásmicas ramificadas de una célula nerviosa que propagan la estimulación electroquímica recibida de otras células neuronales al cuerpo celular), cuerpo neuronal (o soma, es la parte bulbosa de una neurona que contiene el núcleo celular)
