What do you mean by predators?Predators are organisms that hunt and kill other organisms for food. The organisms that are consumed by the predators are known as the prey. Predators can be carnivores and omnivores. Lions, tigers, sharks, and snakes, all are predators.
Moreover, the best-known examples of predation involve carnivorous interactions, in which one animal consumes another. Think of wolves hunting moose, owls hunting mice, or shrews hunting worms and insects.
Therefore, predators are wild animals that hunt, or prey on, other animals. All animals need food to live. Predator animals need the flesh of the animals that they kill to survive. Weasels, hawks, wolves, mountain lions, and grizzly bears are all predators.

NO LINKS The arctic is an environment in which the temperature is often below freezing. The polar bear and the walrus are both animals which are native to the arctic region. What structures do both of these animals share that allow it to survive in this environment? Explain your thinking.
Answer:
Polar bears are found in very cold parts of the world where temperatures can drop as low as -20° Fahrenheit (-29° Celsius). Without proper protection, this weather can be deadly, so polar bears stay warm by utilizing their thick fur and fat, or blubber. Polar bears have evolved along with other Arctic animals to take advantage of minimal warmth, and can sometimes actually become too warm because their bodies are so efficient at trapping heat.
As for walrus', they cannot put on a coat to stay warm, but they can use layers -- layers of blubber! A walrus's hide is about one inch thick. Tucked underneath this tough skin is a layer of blubber. This layer of fat is from three to six inches thick. Just like our layers of clothes, a walrus's layer of blubber helps it stay warm.

Choose the correct connective tissue.
1)Bone to bone
2)Muscle to muscle
-ligament
-tendon
Explanation:
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
A tendon is a fibrous connective tissue which attaches muscle to bone.
A ligament is a fibrous connective tissue which attaches bone to bone.
What is tendons and its function?
A tendon is a cord of strong, flexible tissue, similar to a rope. Tendons connect your muscles to your bones. Tendons let us move our limbs. They also help prevent muscle injury by absorbing some of the impact your muscles take when you run, jump or do other movements.
What is ligament and its function?
Ligaments often connect two bones together, particularly in the joints: Like strong, firmly attached straps or ropes, they stabilize the joint or hold the ends of two bones together. This ensures that the bones in the joint don't twist too much or move too far apart and become dislocated.

Answer:
The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. Respiration happens all the time, but dominates during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.

describe the structure of an atom of argon-38 and argon-40
Answer:
Argon 38 has 18 proton and 20 neutron
Argon 40 has 18 proton and 22 neutron
Explanation:
isotope is same no of proton diff no of neutron
Both argon-38 and argon-40 have 18 protons but they have different atomic masses. The atomic mass of argon-38 is 38u while the atomic mass of argon-40 is 40u. Thus, they are isotopes.
What are isotopes? Some atoms contain the same number of protons (i.e. same atomic number) but they have a different number of neutrons (i.e. different mass numbers). These types of atoms are called isotopes.Argon element has three isotopes namely, argon-36, argon-38 and argon-40. All the three isotopes of argon have the same number of protons i.e. 18. But, all have different numbers of neutrons and thus, different mass numbers. Argon-36 has 18 neutrons, argon-38 has 20 neutrons and argon-40 has 22 neutrons. Thus, the mass numbers of argon-36, argon-38 and argon-40 are 36u, 38u and 40u respectively.Thus, the structure of an atom of argon-38 and argon-40 is slightly different as they are isotopes. Argon 40 has more atomic mass than argon-38. But, both contain the same number of protons. They have similar chemical properties but different physical properties.

What are the answers to 10 and 11?
Answer:
The correct answer is -
10. 20 J
11. 29.31 %
Explanation:
According to the law of 10% energy transfer, the energy only transfers 10% energy from one tropic level to another and the rest 90% lost in the form of heat during the metabolic and excretion process.
So, 2000 J transfers only ten percent to the primary consumer that is 200 J and then ten percent of that transfers to long-tailed weasels that are 20 J.
11. The percentage efficiency -= energy after transfer*100/transfer before the transfer
= 350*100/1170 = 29.31%

A. episodic
B. flashbulb
C. semantic
D. didactic
Answer: A. Episodic
Explanation:
When you see a movie and remember the story because it had meaning to you, you are using Episodic memory.
What is Episodic?The majority of the time, when someone mentions memory, they are referring to episodic memories, which include details of recent or previous experiences and events, such as where you parked your car this morning or the dinner you had with a friend last month.
Three stages of memory processing—encoding, consolidation/storage, and retrieval—are necessary for the memory to be able to recall past events.
The default mode network, which encompasses numerous brain areas including frontal and parietal regions and has been implicated in episodic memory functioning, contains the hippocampus and nearby structures in the temporal lobe, which are significant for episodic memory.
Therefore, When you see a movie and remember the story because it had meaning to you, you are using Episodic memory.

11. Question: Imagine 20 babies were born. 10 had blue eyes, and 10 had brown eyes. What traits do their parents probably have?
Answer:
The correct answer is - brown heterozygous Bb and blue eye bb.
Explanation:
In the provided question it is given that there are 20 babies born, 10 babies had blue eyes and 10 had brown eyes. As it is known that brown eyes are dominant over blue eyes, therefore, on the basis of this we can say that all blue-eyed babies have a bb genotype and as brown eyes are dominant traits babies must have at least one copy of the B allele which represents brown eye trait.
case1:
Parent 1 : bb
parent 2: BB
B B
b Bb Bb
b Bb Bb
there are 100% brown eye offspring so this is not the case
case 2:
Parent 1 : bb
parent 2: Bb
B b
b Bb bb
b Bb bb
here, 50% brown eyes and 50% blue eyes offspring produced thus, the parent trait will be brown heterozygous and blue eye.
