Explanation:
The benefits that trees provide to streams are Trees provide essential nutrients from dead leaves, Trees provide shade to help keep cool water temperatures in the stream, Trees filter stormwater run off which helps keep harmful pollutants out of the stream and Trees provide habitat to wildlife.
How important is the tree to life on the planet?It is the trees that increase the humidity of the air, prevent erosion along the rivers, carry out photosynthesis resulting in the production of essential oxygen for living beings, provide shade and manage to reduce the temperature, reduce air pollution, serve as a shelter for species animals, contributing to respiration.
Trees have numerous health benefits. They absorb carbon dioxide (CO2) and release oxygen, improving air quality and humidity, and can even absorb noise and noise in the city.

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
Both hurricanes and engines are often studied by scientists.
Answer:
C. Both engines and hurricanes need a fuel to power them
Explanation:

Bulbo raquídeo –control de la frecuencia del latido cardíaco. c) ¿Cuál de los siguientes procesos es el resultado de la acción del sistema nervioso parasimpático? A. Dilatación de la pupila. B. Inhibición de la digestión. C. Aceleración de la frecuencia cardiaca. D. Contracción de los bronquios. d) Morfológicamente la neurona consta de: A. Axón, dendritas y cuerpo neuronal. B. Soma, axón y nodos de Ranvier C. Soma y prolongaciones D. Soma y dendritas
Answer:
B) A. FALSO.
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.

A mutation in the gene coding for a single-polypeptide enzyme results in the substitution of the amino acid serine, which has a polar R group, by the amino acid phenylalanine, which has a nonpolar R group. When researchers test the catalysis of the normal enzyme and the mutated enzyme, they find that the mutated enzyme has much lower activity than the normal enzyme does. Which of the following most likely explains how the amino acid substitution has resulted in decreased catalytic activity by the mutated enzyme?
A The substitution decreased the mass of the enzyme so that the mutated enzyme binds more weakly to the substrate than the normal enzyme does.
B The substitution altered the secondary and tertiary structure of the enzyme so that the mutated enzyme folds into a different shape than the normal enzyme does.
C The substitution caused many copies of the mutated enzyme to cluster together and compete for substrate to bind.
D The substitution caused the directionality of the enzyme to change such that the amino terminus of the normal enzyme has become the carboxy terminus of the mutated enzyme.
Answer:
Bats have few natural predators -- disease is one of the biggest threat. Owls, hawks and snakes eat bats, but that’s nothing compared to the millions of bats dying from White-Nose Syndrome. The disease -- named for a white fungus on the muzzle and wings of bats -- affects hibernating bats and has been detected in 33 states and seven Canadian provinces. More than 6.5 million bats have died so far from White-Nose Syndrome. Scientists are working to understand the disease. You can help -- avoid places where bats are hibernating, and if you do go underground, decontaminate your clothing, footwear and gear.

In which types of cells must mutations occur in order for the mutation to be passed on to future generations?
1. Somatic cells
2. Genes
3. Gametes
4. Alleles
Answer:
Genes
Explanation:
Mutations occurs on genes
Answer:
2. Genes.
Explanation:
Mutations can occur in either cell type. If a gene is altered in a germ cell, the mutation is termed a germinal mutation. Because germ cells give rise to gametes, some gamete s will carry the mutation and it will be passed on to the next generation when the individual successfully mates.
In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?
Answer:
This question is incomplete, the complete question is as follows:
- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.
What percentage of offspring are expected to be chestnut?
The answer is 0%
Explanation:
This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.
According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;
BB - B only
bb - b only
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
Bb, Bb, Bb, Bb
All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0% of offspring are expected to be chestnut.

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.
