Which of the following is not an example of sn adaptation
A. arctic rabbit's white fur
B.Person's Blue eyes
C.giraffe's long neck
D.Bears hibernating
Answer:
B. Person's blue eyes
Explanation:
In order for organisms to thrive in the environment, they have to undergo some changes. This process is called "adaptation."
A. The arctic rabbit's white fur is its adaptation to the cold environment in the Arctic area. Thus, this is adaptation.
B. A person's blue eyes doesn't have to do with adaptation; rather, it is connected to "genetics." Such genetic information is being carried by an individual from his/her parents. This makes it the only choice that is not an example of an adaptation.
C. The giraffe's long neck is its adaptation to eating from the treetops since it is a herbivore. This also prevents it from competing with other animals for food.
D. Bears hibernating is a proof of their adaptation to the winter season. Since food is scarce on these months, the bears try to sleep in order to stay alive. This also allows them to stay warm as well.

Which statement about the waves shown is true?
The statement about the wave that is true is wave 3 has lowest frequency. The correct option is C.
What is frequency?The frequency of a repeating event is the number of occurrences per unit of time. It is distinct from angular frequency and is sometimes referred to as temporal frequency. The unit of frequency is hertz, which equals one event per second.
In science and engineering, frequency is an important parameter used to specify the rate of oscillatory and vibration phenomena such as mechanical vibrations, audio signals (sound), radio waves, and light.
The relationship between frequency and wavelength is inverse. The wavelength of the wave with the greatest frequency is the shortest.
One-half the wavelength equals twice the frequency. As a result, the wavelength ratio is inverse to the frequency ratio.
Thus, the correct option is C.

How are humpback whales related to blue whales and minke whales
Minke whales (pronounced mink-ey), are one of the smallest baleen whales in North American waters and are the smallest of the “rorqual” whales. The rorqual whales or “great whale” family include blue whale, fin whale, Bryde's whale, sei whale, and humpback whale.
Humpback whales can be distinguished by their small dorsal fin and long pectoral flippers, and they show their tail flukes more often. Blue whales are the biggest. They are actually grey, but appear aqua under water.

1. what is the difference between P waves and S waves?
2. How do you determine the difference between when a P wave and an S wave arrives at a seismogram location?
Answer:
P waves travels faster than S waves.
Explanation:
P waves travels faster than S waves. It can travel through any kind of material but s waves only travel through solid medium. P waves are smaller in size than s waves. P waves are the first waves to hit seismographs while the s waves are the second wave arrive at a seismogram location, so we can say that the wave which reach first at a seismogram location is the P waves. The speed of the wave shows which wave arrive first at a seismogram location.

The atomic number of argon is 18 and its mass number is 40. Describe the number and type of particles
found in the nucleus of this atom
Answer:
Argon's atoms have 18 protons, 22 neutrons in its nucleus, orbited by 18 electrons- its atomic mass= P 18 +N 22.
Explanation:
Atoms are the most basic unit of matter that makes up elements. Atoms are composed of electrons orbiting neutrons and protons surrounding a nucleus.
The atomic number is defined as the number of protons in an atom, while the atomic mass is the number of protons and neutrons.
The element Argon, Ar is a noble gas, that exists in a gaseous, inert, state at temperature. Its atoms have 18 protons, 22 neutrons in its nucleus, orbited by 18 electrons- its atomic mass= P 18 +N 22.
There are 8 valence electrons in its outer shell, thus:
Ar is not very reactive, as it does not require electron sharing in atomic bonding. It shows low conductivity, as there are no free electronsHow are compounds with ionic and covalent bonds are like
Answer:
An ionic bond is a chemical bond between two atoms in which one atom seems to donate its electron to another atom. Covalent bonds, on the other hand, appear to involve two atoms sharing electrons reach a more stable electron configuration. Some compounds contain both ionic and covalent bonds.
What is the genotype of a person with type A blood, who had a father with type O blood?
IAIB
IAIA
IAi
ii
Answer:
IAi
Explanation:
Blood group in humans is controlled by three alleles namely: iA, iB and i. Alleles iA and iB are dominant over allele i but are co-dominant over one another. The following genotypes with their following blood group are:
iA - blood type A
iB - blood type B
iAiB - blood type AB
i - blood type O
In this case, an individual with type A blood had a father with type O blood. This means that the genotype of the individual will be iAi because the person will inherit the "i" allele from the father but since the "iA" allele is dominant, the type allele will be expressed.
2 ways us humans can relate to the digestive system. 5-6 sentences plzz and thank u
Answer:
The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.
The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.
Bacteria in your GI tract, also called gut flora or microbiome, help with digestion. Parts of your nervous and circulatory systems also help. Working together, nerves, hormones, bacteria, blood, and the organs of your digestive system digest the foods and liquids you eat or drink each day.
Digestion is important because your body needs nutrients from food and drink to work properly and stay healthy. Proteins, fats, carbohydrates, vitamins, minerals, and water are nutrients. Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair.
Proteins break into amino acids
Fats break into fatty acids and glycerol
Carbohydrates break into simple sugars

4. What is the mass of N2H4 gas in a 350.0 mL container at 50.0 °C, if the pressure of the gas is
885.0 torr?
Answer:
0.36g
Explanation:
Given parameters:
Volume of N₂H₄ = 350mL = 0.35dm³
Temperature of container = 50°C = 50 + 273 = 323K
Pressure = 885torr;
760torr = 1atm
885torr = [tex]\frac{760}{885}[/tex] = 0.86atm
Unknown:
Mass of the compound = ?
Solution:
The mass of the compound can be derived using the expression below;
Mass = number of moles x molar mass
molar mass of N₂H₄ = 2(14) + 4(1) = 32g/mol
To find the number of moles;
PV = nRT
n = [tex]\frac{PV}{RT}[/tex]
P is the pressure
V is the volume
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
n = [tex]\frac{0.86 x 0.35}{0.082 x 323}[/tex] = 0.01mole
So,
Mass = 0.01 x 32 = 0.36g
How does an American Bullfrog gain energy for their growth?
Answer:
They gain energy through respiration.
Explanation:
American Bullfrogs, are predators that have high energy requirements for growth and locomotion, and as they do not produce their own energy-rich food, and they consume primary consumers (birds, fish, rodents, etc.) they are secondary consumers.
Consumers are heterotrophs; they eat or consume organic matter (lipids, sugars, proteins, etc.) made for their energy intake by autotrophs. Autotrophs include plants, microbes, and other species that photosynthesize, while animals, like bullfrogs are heterotrophs.
Heterotrophs derive energy through respiring. They burn fuel in mitochondria- high energy ATP is derived from breaking apart the chemical bonds within carbohydrates like glucose. Like all large animals, they carry out aerobic respiration:
C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
The glucose molecule created during this process contains oxygen. Which reactant does the oxygen come from?
Water
Sunlight
Carbon dioxide
Oxygen gas

Answer:
No.
Explanation:
You have mistaken C6H12O6 as Carbon Dioxide. However, this is glucose, so this is sugar. We do not inhale sugar, we obtain it from the food we eat or in the case of autotrophs, from producing it. Thus, the correct answer is C. from the food we eat.
