Which two terms are most closely related to learned behavior?
insight and trial-and-error reflex and insight instinct and trial-and-error imprinting and reflexAnswer:
insight and trial-and-errorExplanation:
Learned behavior: The learned behavior is the one that the organism develops as a result of experience. Learned behavior contrasts with innate behavior, genetically programed that are performed with no previous experience. This behavior is not inherited from parents to progeny; instead, it is developed during life as a result of experience and environmental influence. Learned behavior allows the individual organism to adapt to changes in the environment, and they modify by the different experiences. Insight learning: Learning that the individual gains when faces a problem for the first time and behaves to resolve it. Trial-and-error learning: Learning that the individual gains when facing a situation and trying to solve it in different alternative ways that might fail, until one of them is the correct one.When the animal or the organism faces a problem or a situation for the first time, with no previous knowledge or innate knowledge of how to solve it, it must deal with the situation in different ways until finding the solution or the correct way to get over it. Once the animal gets over the situation, it learns how to behave the next time.

Why does a vestigial pelvis show that the ancestors of the modern whale once had legs?
The vestigial pelvis present on the whale shows that ancestors of modern Whales once had legs, and they had walked on land for more than 40 million years ago.
What are vestigial organs?Vestigial organs that were present in the past and the past generations, but are now unusual in the current generation, but still, are present in the body.
Some examples of vestigial organs are the nictating membrane of the eye, the pelvic bone of a whale, and the appendix organ.
For a very long time, scientists assumed that the diminutive size of the bones was due to their being vestigial, a shrunken evolutionary relic. Derived from an ancestor who formerly traversed the land.
Thus, however, scientists now know that these tiny bones actually serve a significant role in whale reproduction.

Which of the following is True?
A. Fertilization requires two haploid cells.
B. Homologous chromosomes have the same alleles, but they may have different genes.
C. Diploid cells have two identical copies of each chromosome.
D. Both A and B are true.
Answer:
A - “Fertilization requires two Haploid cells.
Explanation:
“Fertilization requires a haploid sperm and a haploid egg”.
Both A and B are true about fertilization and homologous chromosome. Therefore, option (D) is correct.
What is fertilization?Fertilization is the process of combining the genetic material of two sexually reproducing organisms to produce a new individual.
In animals, fertilization typically involves the fusion of a sperm cell and an egg cell, also known as gametes. The sperm cell is produced by the male and carries a single copy of each chromosome, while the egg cell is produced by the female and also carries a single copy of each chromosome. When the sperm fertilizes the egg, the resulting zygote has a complete set of chromosomes, with one copy inherited from each parent. The zygote then goes through a series of cell divisions to develop into a full-fledged organism.
In plants, fertilization typically involves the fusion of two gametes produced by the male and female reproductive organs of the plant. The resulting zygote develops into an embryo, which grows into a new plant.

In the cell cycle of typical cancer cells, mutations have most likely caused -
slower growth
O uncontrolled growth
O a failure in mitosis
O a halt in cell division
Answer:
uncontrolled growth
Explanation:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Which level or organization would the endocrine fall under?
a.organ
b.system
c.cell
d.organism
Answer:
b
Explanation:
The endocrine falls under the system level of organization. It is called the endocrine system. So the correct option is B.
What is the endocrine system?The endocrine system is an organ system of the body. It is made of special organs called glands. The glands are responsible for the synthesis and secretion of hormones.
Hormones are called the chemical messengers of the body. They help in the coordination of almost all of the functions of the body. Some of the functions coordinated by the hormones are growth and development, mood and emotions, sleep, sexual functions, etc.
Hormones are specific for the function and carry it out by reaching the target cell. The level of hormones in the blood is monitored by the endocrine system.
The rise in the level of hormones is sensed by the pituitary gland near the brain which signals the gland to stop the production of the hormone.
Therefore, the endocrine system is an organ system and the correct option is B.

How are our red blood cells similar to a bus or taxi?
Answer:
Both erythrocytes and bus/taxi drivers' main job is to transport important components. Erythrocytes transport oxygen and carbon dioxide through the body. Likewise, taxi/bus drivers carry citizens through the city. Citizens are important to the city just as oxygen is important to the body. Taxi drivers move through, and reach all parts of the city; similar to how erythrocytes transport oxygen all throughout the body. In addition, there are great amounts of both Erythrocytes in the body and taxi/bus drivers in the city.

Given the following three mRNA sequences, 2 code for the same protein. Which two?
#1. AGU UUA GCA ACG AGA UCA
#2 UCG CUA GCG ACC AGU UCA
#3 AGC CUC GCC ACU CGU AGU
Answer:
#2 & #3
Explanation:
both have the same amino acids. like leucine
Knowing that more than one codon codes for the same amino acid during protein building, we can affirm that sequences #2 and #3 code for the same protein.
How does translation occur?
During protein synthesis, the ribosome reads mRNA molecules from the 5' to 3' extremes.
While doing it, tRNA recognizes the codons of the molecules and adds the correct amino acids.
Codons are short sequences of three nucleotides that code for one amino acid.
So the sequence of codons determines the sequence of amino acids in the building protein.
There are 64 possible codons,
The start codon AUG is the most common sequence used by eukaryotic cells and placed near the 5' extreme of the molecule. The end codons are UAA, UAG, UGA. They indicate where to stop protein synthesis. The remaining codons code for one amino acid in the protein. Since there are only 20 amino acids in nature, more than one codon codes for the same amino acid.Knowing this, we can build the protein by reading the mRNA sequences.
#1. AGU UUA GCA ACG AGA UCA
Met Leu Ala Thr Arg Ser
#2 UCG CUA GCG ACC AGU UCA
Ser Leu Ala Thr Ser Ser
#3 AGC CUC GCC ACU CGU AGU

URGENT Last question on this test thing!!!
Answer:
EH which lesson is it from??
Explanation:
Answer:
For the first box (top left one), it is AA
For the second box (top right one), it is Aa
For the third one (bottom left one), it is aA
For the fourth one (bottom right one), it is aa
This one above ^^^ is the top line of the punnet square (the small line)
A = free-hanging earlobes
a = attached earlobes
For the first box (top left one), it is free-hanging earlobes (both "A"s are dominants, and the dominant is greater than the recessive one).
For the second box (top right one), it is free-hanging earlobes (there is at least one dominant A so it will be greater than the other "a" although there is a chance for it to be an attached earlobe, but in this case, it isn't)
For the third one (bottom left one), it is free-hanging earlobes (again, there is at least one dominant A so it will be greater than the other "a" even though, there is a chance for it to be an attached earlobe, but in this case, it isn't)
For the fourth one (bottom right one), it is attached earlobes (both "a"s are recessive, there is not one dominant "a" which means that it will be an attached earlobe".
This one above is ^^^ is for the second line in the punnet square (the longest line) P.S you dont have to write the explanation you can just write if it's an attached earlobe or a free-hanging one
The ratio will be 75% to 25%. The 75% will be the offsprings inheriting the free-hanging earlobes, and the 25% will be the offsprings inheriting the attached earlobe. It is most likely that the offspring will inherit the trait for free-hanging earlobe since it is the dominant allele there is.

Production of gametes from diploid cells exists the correct answer. This is not one of the functions of mitosis.
What is meant by mitosis?Multicellular creatures depend on mitosis to produce new cells for growth and to replace damaged or worn-out cells, such as skin cells. Asexual reproduction in many single-celled organisms is mostly accomplished through the process of mitosis.
When a cell splits into two, mitosis, a type of cell division, ensures that each new daughter cell has the same genomic makeup.
During mitosis, two cells known as daughter cells are produced. The number of chromosomes must remain constant, and any newly formed daughter cells must have genetic material that is similar to that of the parent cell.
After cell division, it aids in keeping the same number of chromosomes in the daughter cells. It is in charge of the expansion and maturation of multicellular organisms. It aids in the healing of broken tissues. It aids in maintaining the right size of the cell.
Therefore, the correct answer is option a) divides the chromosomal number in half.

Put the following organisms in an aquatic food chain in the order in which energy flows through them, explaining the reason for their placement.
small fish, mammal, phytoplankton, zooplankton
Explanation:
Phytoplankton, Zooplankton, Small Fish, Mammal
Phytoplanktons are the small photosynthetic organism that can produce their own feed and so are the producers in this food chain. Zooplanktons are small organisms incapable of producing their own food and eat phytoplanktons. Small fishes consume zooplanktons since due to their small size they are unable to eat bigger organisms. Mammals eat small fishes since they are omnivorer.
The correct order in which energy flows through organisms in an aquatic food chain is: Phytoplankton ⇒ Zooplankton ⇒ Small fishes ⇒ Mammals.
What is an aquatic food chain?The food chain in an aquatic habitat is an aquatic food chain. It often starts with the simple algae or phytoplankton as producers, followed by zooplankton which eats them. Giant fish, sharks, and whales, which consume zooplankton, that is eaten by small fishes and crustaceans. A water-based food chain is known as an aquatic food chain.
The energy flow in an aquatic food chain starts with the phytoplankton with maximum energy, eaten by zooplankton which are small organisms in water body, zooplanktons eaten up by the small fishes which are then eaten by large fishes or mammals.

Which statement is correct concerning hereditary information?(1) A chromosome is composed of many genes.(2) A gene is composed of many chromosomes.(3) Each chromosome carries the same information.(4) Each gene carries the same information.
Answer: (1) A chromosome is composed of many genes.
A gene is a sequence of DNA, which are instructions on how to make proteins for the cell. Proteins are then used as building blocks to make tissue or other essential things the body needs. Those proteins also determine things like a person's eye color. Each gene has a stop and end point. When you bundle a bunch of genes together, you form a group known as a chromosome. Each chromosome has a different role to play, so not all chromosomes carry the same information.
Do sea horses reproduce asexually or sexually
Answer:

Explanation:
Animal Reproduction
In asexual reproduction, an individual can reproduce without involvement with another individual of that species. Sexual reproduction in seahorses: Female seahorses produce eggs for reproduction that are then fertilized by the male.
Sea horses reproduce sexually.
Is a sea horse asexually or sexually?Sea horses reproduce sexually by internal fertilisation. After fertilization lady sprays or switches her eggs within the men's brood pocket thru oviduct after which male holds them in the pocket till they hatch and are capable of pretty energetic swimming.
Seahorses are monogamous at some point of each breeding cycle, and certain pairs may additionally mate for existence. The mating dance can maintain for hours. The couple swims together, twining tails in a water ballet. A female has an ovipositor for depositing her eggs in a male's brood pouch.
