Answer: The endosymbiotic theory suggests that eukaryotic organisms evolve from primitive prokaryotic organisms.
Explanation:
According to the endosymbiotic theory the organelles like mitochondria and chloroplast in the eukaryotic cells have arisen from aerobic bacteria. The aerobic bacteria being prokaryotic cell was consumed by the anaerobic bacteria or prokaryotic cell.
The following are the evidences of the origin of eukaryotic organisms from prokaryotic organisms:
1. The chloroplast and mitochondria have circular DNA like bacteria.
2. The mitochondria and chloroplast reproduce through binary fission which also occurs in bacteria.
Answer:
The Endosymbiotic Theory states that the mitochondrion and chloroplasts were consumed by a cell and now depend on one another to survive. Endosymbiotic Theory helps us by giving us the technology to use forensic sciences to solve cold cases.

44. What are the 3 polymers for nucleic acids.________________________________________
45. What are the 2 main functions for nucleic acids.________________________________________________________________________
Answer:
42. Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine
Explanation:
43.Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.
44.polymer of nucleic acid
33 terms. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Threose nucleic acid (TNA) is an artificial genetic polymer in which the natural five-carbon ribose sugar found in RNA has been replaced by an unnatural four-carbon threose sugar.

Which term refers to one species eating another, such as the red-tailed hawk
eating the prairie dogs?
A. Prey evasion
B. Interspecific competition
C. Predation
D. Herbivory
Answer:
Predation
Explanation:
Predation is the interaction where one organism, the predator (red-tailed hawk), kills and eats another organism, its prey (praire dog).
It is not the other three because:
Prey evasion is when the prey attempts to avoid its predator; however, in this case, the prairie dog is being eaten by the red-tailed hawk.
Interspecific competition is when individuals of different species compete for the same resources in an ecosystem.
Herbivory is the consumption of plant material by animals, and herbivores are animals adapted to eat plants. There are no plants being involved in this scenario.

Which function of the integumentary system is illustrated in the release of sweat? A. Absorption B. Protection C. Sensory Reception D. Regulation E. Secretion F. Both regulation and secretion
Answer:
F. Both regulation and secretion
Explanation:
Through sweat glands and superficial blood vessels, the skin is able to cool the body and regulate its internal temperature.
The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.

A young child does something he knows is wrong and immediately looks at an adult for a reaction. This child has learned to?
Answer:
This child has learned to act from its adults.
Explanation:
This child has learned to act according to the reaction of the adult. If a child done something wrong and the adult reaction is not good the child will not repeat it because he knows that this act is bad while on the other hand, when the child done something good and the adult gives a good reaction so the child will continue doing this action so we can say that a child learn most of the things from their adults.
what are 5 functions of carbohydrates
☁️ Answer ☁️
PROVIDES INSTANT ENERGY TO THE BODY:
This appears to be the primary function of carbohydrates in the body.
Carbohydrates which we consume as food in the form of starch (ex: potato, bread), sucrose (ex: sugar, fruits), etc. get digested in the body to release glucose.
RESERVE FOOD:
Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.
CARBOHYDRATES FORM OTHER BIOMOLECULES:
Carbohydrates in excess are converted into other bio-molecules of physiological importance. They mostly get stored in the form of fats.
DETOXIFICATION OF THE BODY BY METABOLISM:
Many drugs and toxic wastes in the body are metabolized for easy excretion in the body.
SPARING PROTEIN
In a situation where there is not enough glucose to meet the body’s needs, glucose is made from amino acids. Because there is no storage molecule of amino acids, this process requires the destruction of proteins, primarily from muscle tissue. The presence of adequate glucose basically spares the breakdown of proteins from being used to make glucose needed by the body.

The central nervous system (CNS) processes sensory inputs and initiates appropriate motor outputs. Therefore, option C is correct.
What is the central nervous system?The brain and spinal cord make up the central nervous system. The brain directs our thoughts, memories, movements, and emotions. Between the brain and the nerves that run throughout the body, the spinal cord relays messages.
It regulates cognition, personality, memory, emotion, speech, and the capacity to feel and move. The corpus callosum, a band of nerve fibers in the middle of the brain, connects the left and right hemispheres of the brain.
Thus, the central nervous system (CNS) processes sensory inputs and initiates appropriate motor outputs. Therefore, option C is correct.

The strangler fig is a vine that starts out as a seed in the tree canopy of the rain forest. It drops its roots down from the canopy to the forest floor. By sprouting in the rain-forest canopy, the strangler fig seedling is exposed to more-
The strangler fig plant shows an aggressive growth habit as an adaptation that allowed its growth. It drops to the forest floor and develops its seeds by exposure to sunlight. Thus, option A is correct.
What are adaptations?Adaptations are a crucial part of the evolutionary process that allows the organism to fit and survive in altered environmental conditions. It has been due to the process of natural selection that gets inherited.
The aggressive growth habit of the strangler fig vine is to ensure its survival in the rainforest covered in canopies. The seed of the plants uses sunlight and nutrients to grow at a faster rate and hangs their roots on the first floor. The sunlight increases its rate of germination.
Therefore, option A. sunlight is used for germinating the fig seeds.

You come up with an example and figure out the "because" part of the answer on your own.
Answer:
A variation is different to an adaptation as a variation is a difference or variety inside a species, for example a different breed of dog such as a spaniel is a variety of the dog species, whereas an adaptation is a genetic mutation that has developed in order to help an animal survive, such as giraffes having a long neck. Adaptations continue throughout the species due to natural selection.

a - 0%
b - 50%
c - 100%
d - Impossible to tell
Answer:
Option A is the correct answer.
- 0%
Explanation:
This is because the male is hemophilia recessive, not dorminant and the female allele has no traits of hemophilia therefore, the offspring have zero percent of having the diseases. The girl allele will be normal and recessive of hemophilia. Because there is no dorminant allele that can result into hemophilia.
