The image below represents two waves X and Y, traveling to the same medium at the same speed how are the two waves different?
Answer: D is right
Explanation: It seems both waves have same wavelength.
Because speed = wavelength · frequency (v = λf) and
f = v/λ, so frequency is same. Because period T = 1/ frequency, also periods are same. Wave Y has higher amplidude and its energy is greater.
Answer:
D

What are the reactants in
photosynthesis?
Explanation:
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
Alina notices that when she shines a desk lamp on a mirror, nothing happens.When she shines an infrared lamp on the mirror, the mirror starts to get warmer.Why does light from the infrared lamp warm the mirror when light from the desk lamp does not?
Answer:
Because the infrared lamp gives off a type of light that the desk lamp does not, and the mirror can only take in the energy from the infrared light.
Explanation:
Answer:
Explanation:
Infrared is used for incubators when a chicken egg is about to hatch. It is the electrical frequency of electromagnetic radiation the provides heat.
Because heat is produced electrically it can be controlled with something resembling a dimmer switch (the kind of switch that dims lights in romantic restaurants). That means that the temperature can be set to the hen's body temperature.
Infrared is just below visible light.

A scientist studying fossils in undisturbed layers of rock identified a species that appeared to not have changed a lot over the years. Which observation would have most likely led him to this conclusion?
Answer:
After studying the fossil, the person can figure out which animal it might be of the records of animals we know of, by taking bone tests, etc. they can see the DNA of the animal. The bone structure can show the animal looked different, or even could figure that out through the DNA. During the years, it could've mated with other animals creating an updated breed, or simply just changing to fit into new environments aka evolving

describe the following Characteristics of Life display organization growth development requires energy reproduction respond to stimuli and maintains homeostasis
Answer:
These characteristics of Life are very important.
Explanation:
Organization growth, development requires energy, reproduction respond to stimuli and maintains homeostasis are the characteristics of Life. These characteristics are very important for survival and for a good life. In the absence of these characteristics, the organisms will die. Energy is required for the growth and development of an organisms. Equilibrium is maintained in the body of organism by maintaining homeostasis in the body which resist change in the body.
1. The energy that cells need for cellular processes
is found in the chemical bonds that make
up
what
molecule?
a. water
C. ATP
b. glucose
d. ADP
The energy that cells need for cellular processes is found in the chemical bonds that make up ATP (adenosine triphosphate).
What is ATP?ATP, or adenosine triphosphate, is a molecule that stores and provides energy for cellular processes. It is often referred to as the "energy currency" of the cell. ATP is composed of three phosphate groups, a sugar molecule (ribose), and a nitrogen-containing base (adenine).
The energy stored in the bonds between the phosphate groups is released when the last phosphate bond is broken, forming ADP (adenosine diphosphate) and a free phosphate group. This process, called hydrolysis, releases energy that is used by the cell to drive metabolic processes such as muscle contraction, nerve impulse transmission, and protein synthesis.
ATP is produced in the mitochondria through cellular respiration and is constantly recycled within the cell to provide energy for ongoing cellular processes.

In mice, albinism (b) is recessive to normal brown coloration (B). When an albino female was crossed with a brown male, they produced 2 brown offspring and 2 albino offspring. What is the genotype of the brown male parent?
Answer:
Bb is his genotype. He passed his dominant allele 50% of the time and his resessive allele 50% of the time.
In humans, widow's peak (A) is dominant over a continuous hairline (a), and short fingers (B) are dominant over long fingers (b). Two individuals with widow's peak and short fingers have a child with continuous hairline and long fingers. Determine the genotypes of the parents.

Each parent provided one allele for each trait to the child. So the child inherited one recessive allele a and one recessive allele b from EACH parent. The fact that both parents could provide one recessive allele to the child for each character, indicates that both parents are heterozygous for the trait. It is the only way of having a child who expresses the double recessive trait.

Describe, in three or four steps, how toxins get more concentrated in organisms going up the food chain
Please help me
Explanation:
Small amounts of toxic substances - often pesticides or pollution from human activity - are absorbed by plants.
These plants are eaten by primary consumers in low concentrations.
The toxin cannot be excreted so when the primary consumers are eaten by secondary consumers all the toxin is absorbed by the secondary consumers.
This repeats as secondary consumers are eaten by higher level consumers.
At each trophic level of the food chain, the toxins remain in the tissues of the animals - so the concentration of toxin becomes most concentrated in the body tissues of the animals at the top of the food chain.
Why is the genetic code common to all organisms!
Answer:
Why Is DNA Considered a Universal Genetic Code? DNA is considered a universal genetic code because every known living organism has genes made of DNA. ... All organisms also use DNA to transcribe RNA, and then they translate that RNA into proteins. Every living organism uses that same system.
Explanation:
The genetic code is universal because it is the same among all organisms. Replication is the process of copying a molecule of DNA. Transcription is the process of converting a specific sequence of DNA into RNA.
Protein-encoding genes specify the sequences of amino acids, which are the building blocks of proteins. In turn, proteins are responsible for orchestrating nearly every function of the cell. Both protein-encoding genes and the proteins that are their gene products are absolutely essential to life as we know it.

Un tanque cilindrico de gasolina tiene 3 m de altura y 1.2 m de diámetro. ¿Cuántos kilogramos de gasolina es capaz de almacenar el tanque?
Plan: Para calcular la masa, primero debemos determinar el volumen del cilindro circular
derecho (V = irr2h), donde r = jD = 0.60 m. Por tanto, la masa se determina a partir de
la ecuación (15.1).
Solución: El volumen es
V = 7rr2h = 7t(0.6 m)2(3 m); V = 3.39 m3
Al resolver la ecuación de la densidad para m tenemos
m = pV = (680 kg/m3)(3.39 m3); m = 2310 kg
Otro método para indicar las densidades de las sustancias es la comparación su densidad
con la densidad del agua. La relación de la densidad de la sustancia con respecto a la del agua
se vuelve entonces la gravedad específica, la cual es una cantidad sin dimensiones. Si un
objeto tiene el doble de densidad que el agua, su gravedad específica es 2; un objeto que tiene
una tercera parte de densidad que el agua tiene una densidad relativa de 1/3.
La gravedad específica de una sustancia se define como la razón de su densidad con respecto a la densidad del agua a 4°C (1 000 k g /m 3).
Un mejor nombre para esta cantidad es densidad relativa, pero el término gravedad específica
se usa más ampliamente.
