Answer: c. that microevolution is only for small organisms, and macroevolution is for large organisms
Explanation:
Evolution can be defined as the gradual changes that occur in a population of a species or in an individual which supports its survival in the changing environment. Microevolution can be defined as the changes that occur during lifetime in an organism, whereas multiple changes occurring in the organisms over multiple generations. The microevolution is effective over small organisms like insects whereas macroevolution works on large organisms like whale. As the scale of evolution is low in microevolution as small number of changes occur whereas in case of macroevolution the scale of evolution is high so more changes will occur multiple times in an organism.
Answer:
the correct answer is - the species that evolve during each

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.

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.

Which of these four solutions will dissolve the plastic wrapper fastest?
Water
Boiling water
Apple cider vinegar
Soda
Acetone
Answer:
Acetone
Explanation:
Answer: Acetone.
Explanation: Acetone molecules have a polar carbonyl group that allows them to ACCEPT hydrogen bonds from OTHER compounds. The slightly positive charge on each hydrogen can attract slightly negative oxygen atoms on other water molecules, forming hydrogen bonds. If acetone is added to water, acetone would completely dissolve.

When a stream's velocity decreases from 300 to 200 centimeters per second, which size sediment will be deposited?
Middle size sediment will be deposited on the ground when the speed of flowing water decreases.
Deposition of sedimentsWhen a stream's velocity decreases from 300 to 200 centimeters per second, the middle size sediment will be deposited because of the lowering velocity of the stream. Big size sediments hardly move by the water of the stream.
While on the other hand, middle and small sized sediments easily moved by the flowing water due to their light weight so we can conclude that middle size sediment will be deposited on the ground when the speed of flowing water decreases.

write a 5-7 sentence paragraph explaining what happens to co2 levels in the world over the course of the year. add as much context and details as you can
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.
Explanation:
Chromosomes often exchange segments of DNA during meiosis. How might this increase the survival of a species?
Answer:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase

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.

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.
