Answer:
punctuated equilibrium
Explanation:
The punctuated equilibrium theory is a model of evolution by bursts of speciation, which was proposed by the paleontologists Niles Eldredge and Stephen J. Gould (1972). The theory of punctuated equilibrium states that evolution is characterized by rapid changes followed by longer periods of stasis where little observable evolution seems to occur judging from the fossil record. The punctuated equilibrium theory does not propose that Darwin's evolutionary gradualism is wrong, but this theory suggests that important evolutionary changes occur in short periods of time that are linked to speciation events. In consequence, fossils record does not represent transitional forms because of their small population size compared to the observed in stasis periods.

Muscle cells combine to form __________.
A. muscle tissue
B. brain tissue
C. bone tissue
Answer:
the answer is A........
Answer:
A. Muscle Tissue
Explanation:
Cells are the basis in creating tissues, which are the basis in creating organs, which are the basis in making the organ system.
In this case, the cells given to you are muscle cells. Using the description above, the next logical "upgrade" would be a muscle tissue, followed by a muscle, and then the muscular system.
10. Refer to p. 484 of your textbook. In sex-linked heredity, the characteristic gene is found on the X
(sex) chromosomes; therefore, it is inherited along with the sex of the individual. Hemophilia (X") is
the result of a recessive sex-linked allele. A carrier has one recessive allele for hemophilia; therefore,
she does not have hemophilia but can pass it on. If a normal male marries a carrier, what is the
probability that they will produce a male child who will be a hemophiliac? What is the probability
that they will produce a female child who will have the disease? What is the probability that they
will have a daughter who is a carrier?
Answer:
they have a chance of 25% of producing a male child who will be haemophiliac.
Explanation:
0% of producing a female child who will have haemophilia
25% of having a daughter who is a carrier

How does ADH work to balance water in the bloodstream and urine??
Answer:
The kidneys can adjust the concentration of the urine to reflect the body’s water needs, conserving water if the body is dehydrated or making urine more dilute to expel excess water when necessary. ADH is a hormone that helps the body to retain water by increasing water reabsorption by the kidneys.

Three human disorders−−fragile X syndrome, myotonic dystrophy, and Huntington's disease−−are conceptually linked by a common mode of molecular upset. Choose the phenomenon that links these disorders. Three human disordersfragile X syndrome, myotonic dystrophy, and Huntington's diseaseare conceptually linked by a common mode of molecular upset. Choose the phenomenon that links these disorders. All three are caused by disparate genes, but each gene was found to contain repeats of the same trinucleotide sequence. All three are X-linked, but each gene was found to contain repeats of the same trinucleotide sequence. All three are caused by disparate genes, but each gene was found to contain repeats of a unique trinucleotide sequence. All three are X-linked, but each gene was found to contain repeats of a unique trinucleotide sequence.
Answer:
The correct answer is ''All three are caused by disparate genes, but each gene was found to contain repeats of a unique trinucleotide sequence.''
Explanation:
Four groups of trinucleotide repeats related to DNA expansion have been characterized in the human genome. CGGI GCC, CAGIGTC, CTGIGAC and recently GW CTT sequences. The CGGl GCC sequences are usually located in the noncoding regions of different genes and when expanded they associate with fragile sites on the chromosomes. The CAGIGTC repeats are part of the coding region and are related to different neurodegenerative disorders. You can try to make a classification depending on the unit that is repeated, having on one side a group that are caused by repeats of the CAG trinucleotide (cytosine, adenine, guanine). Huntington's disease (HD) is a progressive disorder of motor, cognitive and psychic function. The disease is inherited in an autosomal dominant manner, and is caused by the expansion of CAG trinucleotide repeats in exon 1 of the gene called huntingtin (HTT or IT-15). Unstable mutations have also been found in which the repeat unit does not is composed of three nucleotides, if not four, such as type 2 myotonic dystrophy, where the tetranucleotide CCTG repeats. Fragile X Syndrome consists of an abnormal expansion of the cytosine-guanine-guanine trinucleotide (CGG) in the FMR1 gene, which prevents intellectual disability and also influences the formation of connective tissue

Which two inferences about the chipmunk population can be supported with the data gathered by the biologist?
Answer:
The amount of food in the area decreased, causing more chipmunks to
survive to reproductive age.
Explanation:
Hope this helps :)
Chipmunks in later generations showed greater genetic diversity than previous generations, allowing for a greater survival rate in later generations. Individual chipmunks changed their genetic makeup and became more successful in the environment. The correct options are R and S.
What is genetic diversity?Genetic diversity refers to the total number of genetic traits that make up a species' genetic composition.
It varies greatly depending on the number of species present as well as across species, and it can be linked to a species' longevity.
DNA contains all the biological information and variety required to sustain life on our planet.
Genetic variety is referred to as this. It improves a species' and population's resistance to maladies, pests, climatic changes, and other pressures.
According to the findings, Chipmunks had a higher genetic variety in later generations than in earlier generations, which allowed for a higher survival rate in later generations. Individual chipmunks altered their genetic make-up and improved their chances of survival.
Thus, the correct options are R and S.

findings are shown.
Years 1 – 20:
• The population remains below
125.
• Less than half of newborn
chipmunks survive to adulthood.
• Competition for food and
resources limits population
growth.
Year 21 and beyond:
• Ninety percent of newborn
chipmunks survive to adulthood.
• The population increases to over
200 chipmunks.
M. The amount of food in the area decreased, causing more chipmunks to
survive to reproductive age.
P. Chipmunks in later generations showed greater genetic diversity than
previous generations, allowing for a greater survival rate in later generations.
R. Chipmunks migrated from one country to another country to increase the
number of chipmunks in the studied area.
S. Individual chipmunks changed their genetic makeup and became more
successful in the environment.
T. The number of predators in the area decreased, so more chipmunks were
able to survive.

Why humans need organs, like the liver and pancreas, but amoebas do not.
Answer:
They have no use for it, just like they dont have any type of respiratory organs like lungs.
Explanation:
In the case of nutrition and digestion they obtain food by capturing their prey with their pseudopodia. The food is internalized through a type of endocytosis known as phagocytosis. Nutrients are obtained as the enzymes digest the food inside the vacuole and when they are finished the food vacuole dissolves.
Humans need organs, like the liver and pancreas, but amoebas do not because human is a complex multicellular organism that necessarily requires a variety of organs in order to perform specific functions.
What do you mean by Organs?Organs may be characterized as collections of tissues as a part of the body that performs a specific function. Some examples of organs may include the heart, the lungs, the kidneys, the stomach, etc.
Amoeba being unicellular organism has the capability to change their shape. They capture their food through pseudopodia and diffuse the substance easily through their single cells.
While on contrary, humans are more complex living organisms on this earth planet. So, they require a specific set of organs and organ systems in order to facilitate their survival.
