What is the difference between causal and correlation relationships?
Explanation:
correlation relationships are between variables, however,it does not automatically mean that the change in one variable is the cause of the change in the values of the other variable. Causation indicates that one event is the result of the occurrence of the other event there is a causal relationship between the two events.
Hope this helps let me know if this was what you were asking for.
The difference between causal and correlation relationships is that
correlation relationships involves two variables in which a change in one
brings about a change in the other while a causal relationship is defined as
an explanation or reason as to why an event occurred
Causal relationship is often referred to as a correlation relationship with a
defined reason or explanation. it is also important to note that not all
correlations imply causation as reasons for some occurrences aren't always
known.

Scientists have recently rejected "Protista" as a kingdom because as evolutionary and molecular knowledge continues to increase, the relationships among organisms are strengthened that weren't previously considered. It continues to be found that many protists don't share common ancestry with other protists that don't exclude other groups, such as plants, animals, and fungi. Protists had been previously classified through what they are not: plants, fungi, or animals. They share no characteristics that aren't also shared by "nonprotists."
The three main ways protists can move are through cilia, flagella, and pseudopods. All of these structures help protists to move in different ways through their environment.
The eukaryote that causes red tide is known as a dinoflagellate.
The eukaryotes that push carbon to the bottom of the ocean are known as diatoms. This is important to the ecosystem because it lowers the overall carbon dioxide levels in the air and buries the carbon deep in the sea.
The endosymbiotic theory posits that eukaryotes emerged when one or more prokaryotic cells ingested another prokaryotic cell, leading to the eventual eukaryotic cell.

recessive allele?
30%
A The recessive form of the trait shows.
B Offspring display both forms of the trait.
80%
O
C Offspring display an intermediate form of the trait.
60%
D The dominant form of the trait shows.
Answer:
The correct answer is : The dominant form of the trait shows.
Explanation:
In simple dominance, the attribute related to the prevailing or dominant allele is communicated while the character related to the latent or recessive allele is persecuted or masked. For instance –
Taking a bloom where the dominant allele attribute is red shading and the recessive allele characteristic is white shading. At the point when a posterity of this bloom is created containing one prevailing or dominant allele and one passive allele, its shade would be red simply because just the predominant allele communicates its characteristic.
Thus, the right answer is: The dominant form of the trait shows.

The theory should be sufficiently defined so that it is possible to differentiate a relevant experiment or observation from one that is irrelevant. Similarly, every effort should be made to separate causality from correlation, and to identify or rule out alternate causes or additional causes from the one(s) theorized. Experiments should be sufficiently well-defined so that they can be reproduced.

Answer:
Receiving sensory information and carrying commands to the muscles.
Explanation:
The spinal cord serves as the transmission conduit for the passage of action potential as sensory information through the sensory/afferent neurons to the dorsal roots of the spinal cord.The information synapse with the inter neurons,branching off to the brain and emerged as the response through the motor/efferent neurons to the effectors(muscles).
This pathways is called reflex arc. Thus most of the involuntary action of the body is conducted through the spinal cord
Answer:
Explanation:
Spinal cord is made of tissue and it runs from the medulla oblongata in the brain to the vertebral column in the lumbar region.
Functions
Receiving sensory information and carrying commands to muscles
They receive sense of body movement through receptors which then travels along the spinal cord.
They also transmit information through impulses to the brain using the nerves cells this include pain and pressure.
They also control voluntary and involuntary movement such as walking neurons that controls voluntary actions passes through the spinal cord.
Describe the animals and vegetation that you see in the different climate zones.
Answer:
Explaining Below V
Explanation:
There are 5 different kinds of climates globally.
Tropical
Dry
Temperate
Continental
Polar
Tropical climates are very hot and humid. There's lots of rain (estimated around 59-60 inches per year). The average temperature tends to be over 60°F or 18°C. Plants you can find are incredibly diverse in both plants and animals. You can find animals such as monkeys, parrots, anacondas, jaguars, tigers, and many more. The tropics have the greatest plant diversity on the planet. The climate generally is centered around the equator.
Dry climates are generally very warm and dry. Humidity is very unlikely as everything is mostly dry heat. There's very little precipitation. Dry climates usually consist of deserts (Fe: Sahara desert). Plants such as cacti, succulents, wildflowers, and small trees, shrubs, and grasses. Animals can vary from things such as tarantulas, rattlesnakes, foxes (only some), camels, and rabbits. Depending on the desert, the heat can shoot up past 100°F while being frigid at night.
Temperate climates are generally warm summers with storms and mild winters. Plants can range from owls, raccoons, sparrows, meadowlarks, deer, and occasionally bears. This climate fluctuates the most in temperature compared to other climates. Plants can range from things like clover plants to a common bean.
Continental climates have mediocre summers with very cold winters. In the winter, snowstorms and strong winds are most likely. Sometimes, the temperature can drop below -22°F. Plants can range from Lavender and fern to Carolina Lupine and Silver maples. Animals can consist of squirrels, chipmunks, prairie dogs, skunks, and raccoons.
Polar climates are frigid. Its cold year round. There's animals such as polar bears, foxes, wolves, and caribou. Plants can vary from Tundra moss to Arctic Willow. Plants are generally smaller and are more like tiny shrubs.

Orange coat color of cats is due to an X-linked allele (Xo) that is codominant with the allele for black (X+). When genotypes at the orange locus were determined for a sample of cats in Minneapolis and St. Paul, Minnesota, the following data were obtained:XoXo females: 11XoX+ females: 70X+X+females: 94XoY males: 36X+Y males: 112Calculate the frequency of the XO and X+ alleles (Y does not contribute) for this population.
Answer:
The X₀ frequency is 0.26
The X+ frequency is 0.74
Explanation:
Available data:
The orange coat color of cats is due to an X-linked allele (Xo)X₀ is codominant with the allele for black X+X₀X₀ 11X₀X+ 70X+X+ 94X+ Y 112X₀ Y 36To alculate the frequency of the X₀ and X+ alleles you need to sum the times it appears X₀ and the times it appears X+ alleles in the population. These sums will give you the number of alleles. As you need to calculate the frequency of these alleles, you will have to divide each number by the total number of both alleles together. This is:
X₀ = 2 x (X₀X₀) + (X₀X+) + (X₀Y) = (2 x 11) + 70 + 36 = 128X+ = 2 x (X+X+) + (XoX+) + (X+Y) = (2 x 94) +70+ 112 = 370The total number of alleles in the population is 128 + 370 = 498
To talculate the allele frequencies, f, you need to divide each allele number by the total allele number:
f (X₀) = 128/498 = 0.26
f (X+) = 370/498 = 0.74

1. State one reason deforestation is occurring.
Add text here!
2. State one environmental problem that results from widespread deforestation.
Add text here!
3. State one way to lessen the effects of deforestation, other than planting trees.
Add text here!
1) One reason why deforestation is occuring because people need wood from trees to build things, therefore, leading them to cuting countless of trees.
2) One environmental problem that results from widespread deforestation is that the carbon dioxide they would normally use remains in the atmosphere, therefore, promoting erosion.
3) One way to lessen the effects of deforestation is by re-planting the cut-down trees and by cutting down less trees.

An 81-year-old woman with RA) has been controlled with methotrexate for 18 years. Recently she experienced increased joint pain and swelling in her right knee that have affected her mobility and activity level. She walks with a cane in the community but uses a walker at home. Earlier in the week, she almost fell while walking to her car after she left the bank. The rheumatologist plans to add etanercept (Enbrel) to her drug regimen.
With what members of the health care team might you collaborate as part of her plan of care?
Answer:
It is imperative to include immunologists and dermatologists to the care team.
Explanation:
Methotrexate is an antimetabolite drug that is used to treat different diseases including, arthritis rheumatoid and psoriasis, this medicament is known to reduce cell growth and to decrease the immune system responses. Moreover, etanercept (Enbrel) is a tumor necrosis factor-inhibitor drug that also is used to treat rheumatoid arthritis and psoriasis. In addition, this drug has also been associated with the functioning of the immune system by altering inflammation responses in the body.
In consequence, it is necessary to include in the health care team both immunologists, in order to study the effect of these drugs on the immune system (like inflammatory responses, for example), and dermatologists in order to examine their effects on skin associated-conditions (like arthritis-like psoriasis).
An individual has a mutation in the gene that codes for hemoglobin. This results in sickle cell disease. Choose the correct explanation for how this mutation affects the individual's traits.
a. The error in the DNA sequence results in an error in the mRNA molecule during transcription, the error in the mRNA molecule results in an incorrect amino acid in the hemoglobin protein which makes it non-functional. The resulting trait is sickle cell disease.
b. The error in the mRNA sequence results in an error in the DNA molecule during transcription, the error in the DNA molecule results in an incorrect nucleic acid in the hemoglobin protein which makes it non-functional. The resulting trait is sickle cell disease.
c. The error in the DNA sequence results in an error in the mRNA molecule during transcription, the error in the mRNA molecule results in an incorrect nucleic acid in the hemoglobin protein which makes it non-functional. The resulting trait is sickle cell disease.
d. The error in the mRNA sequence results in an error in the DNA molecule during transcription, the error in the DNA molecule results in an incorrect amino acid in the hemoglobin protein which makes it non-functional. The resulting trait is sickle cell disease.
Answer:
a
Explanation:
The correct answer would be that the error in the DNA sequence results in an error in the mRNA molecule during transcription, the error in the mRNA molecule results in an incorrect amino acid in the hemoglobin protein which makes it non-functional. The resulting trait is sickle cell disease.
The direction of the flow of information during genetic inheritance is from DNA to mRNA and finally to protein. The information in the DNA is encoded into mRNA during transcription and the encoded information is translated into protein during the process of translation.
Hence, once there is an error in the DNA, the error is passed on to the mRNA during transcription. The consequence of this error is that the wrong amino acid is translated from the wrong codon.
Hence, the substitution of the correct amino acid by the wrong one in the hemoglobin protein results in a defect or non-functional protein. One of the phenotypic implications of this kind of error is sickle cell disease.
The correct option is a.
An error in DNA results in an error in mRNA during transcription, thereby resulting in an incorrect amino acid in the hemoglobin protein which makes it non-functional, producing sickle cell disease (Option a).
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an organism.During gene transcription, a specific fragment of DNA called 'gene' is used as template to create a complementary RNA sequence known as messenger RNA (mRNA).Subsequently, this mRNA is used as a template to create a protein in the ribosomes by a mechanism called translation. The triplets of nucleotides or 'codons' in the mRNA sequence determine the correct order of amino acids that will be added to the growing polypeptide (in this case, the hemoglobin protein).In conclusion, an error in DNA results in an error in mRNA during transcription, thereby resulting in an incorrect amino acid in the hemoglobin protein which makes it non-functional, producing sickle cell disease (Option a).
