organs in each organ system all work together to perform a particular task.
the organs are arranged into 11 organs systems but 4 for example are the skeletal system, respiratory system, digestive system and nervous system.
hope this helps!!!
The organs are systematically arranged into organ systems in order to perform a specific task. They work on the principle of teamwork whose task is equally distributed among the various organs in order to synthesize an organ system.
What is an Organ system?An organ system may be defined as a biological system comprising a cluster of organs that significantly work together in order to perform one or more specific functions.
The four examples of the organ system are as follows:
The Respiratory system: It is a biological system that comprises specific organs and structures utilized for the process of gas exchange in animals and plants.The Circulatory system: It is also a biological system that deals with the flow of blood, oxygen, and nutrients to each and every cell of the organism. The Excretory system: This biological system includes all those organs like kidneys, nephrons, etc., and deals with the elimination of waste materials from the body in the form of feces, or urine. The nervous system: It is a complex network of neurons and cells that carry messages to and from the brain and spinal cord to various parts of the body.Therefore, it is well described above.

Homologous recombination occurs in a heterozygote in which alleles D and d differ by a single base pair. The D allele has a G (a GC base pair) at one position, whereas the d allele has a C (a CG base pair) at the same position. If branch migration causes heteroduplex formation across this position, what is the expected outcome
Answer:
Mismatch DNA repair mechanism recognizes the abnormal base pairing (G-G base pair) and may correct it by converting the D allele to d
Explanation:
The DNA mismatch repair can be defined as a specialized mechanism that recognizes and repairs errors in the nuclotide sequence (such as, for example, bases erroneously incorporated) during DNA replication and recombination. The DNA mismatch repair is a system that also acts to repair the DNA after damage. It has been shown that the DNA mismatch repair mechanism leads to the generation of a DNA molecule with one chain that has the nucleotide sequence arising from DNA repair and one parental chain. In this case, it is expected that the DNA mismatch repair mechanism will identify the abnormal G-G base pairing and then this system may change the D allele to a d allele by introducing a C base instead of a G base in the DNA strand.

Answer:
Adaptation and extinction occur as a result of long term change whereas loss of habitat and forced migration results of short term change.
Explanation:
Adaptation and extinction occur as a result of long term change in the environment whereas loss of habitat and forced migration is a result of short term change in the environment. Adaptation occurs in the organism as a result of climate change because when the climate change occurs some organisms are extinct due to intolerance of the change environment whereas some organisms adapt the environment by making some changes its physical structure in order to survive. Loss of habitat and forced migration occurs due to sudden big change in the environmental conditions such as flooding and volcanic eruptions.

Answer:
apes are very related to humans. there's only one difference in their dna sequence.
sharks are least related to humans because we diverged from them a long time ago through divergent evolution.
humans and apes share homologous structures such as arms, legs, tailbone, and fingers that are similar in function.
the differences between humans and apes are that they have a tail, whereas we do not, and their vocal cord hasn't evolved as much as ours.
apes are more vulnerable since they can't innovate weapons and defend themselves with tools like we once did.
humans are more likely to survive because we are strong in number, and our teamwork can triumph any challenges.
A group of white, grey, and black rabbits lives in Alaska, where there is usually snow on the ground. Wolves that hunt the rabbits end up mostly catching ones with grey and black fur. As a result, white rabbits become more prevalent in the population. This is an example of:
Answer:
Directional selection
Explanation:
Natural selection is the process by which environment selects from a population of organisms which individuals are better suited and adapted to that environment. There are three types of natural selection namely: directional selection, disruptive selection and stabilizing selection.
Directional selection is the type of natural selection in which only one extreme (phenotype) of a population is favored over the other extreme and intermediate individuals. This is the case in the example given in the question where among a group of white, grey, and black rabbits that lives in Alaska, environment selects the white rabbits (one extreme) from wolf predation, hence, causing the white rabbit population to increase and be favored.
Explain the differences between eukaryotic and prokaryotic cells.
Explanation:
Comparing prokaryotes and eukaryotes
All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.
What can we do in lieu of a breathable atmosphere
Answer:
Explanation:
I wonder how you would explain that both men and women are living much longer. In 1900 the average ago of mortality was 42 years old in the United States. We have nearly doubled that. In the province (Canada) where I live the mortality rate is nearly 81 years old. That is a huge improvement.
We have done in spite of contaminated air, oceans that resemble sewage sump (there is a plastic dump the size of Texas somewhere in the Pacific and the Atlantic is little better), a population increase that is unbelievable in terms of %. I wish my stocks would show that kind of % increase, and the current biological crisis -- I'm not allowed to name it. (There have been several of these pandemics since 1900.)
So I'll ask again: How are such things to be explained.
In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g). A student performed a cross between a plant that produced green melons and a plant that produced yellow melons. When the student observed the next generation, the 94 seeds that were produced from the cross matured into 53 plants with green melons and 41 plants with yellow melons. Calculate the chi-squared value for the null hypothesis that the green-melon parent was heterozygous for the melon-color gene.
Answer:
4.26
Explanation:
Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.
Observed(o) Expected(e) (o-e) [tex]$(o-e)^2$[/tex] [tex]$(o-e)^2/e$[/tex]
Green-melon plant 53 47 6 36 0.766
Yellow-melon plant 41 47 -6 36 0.766
Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.

What are the weaknesses or inaccuracies in the
model the student created?
Answer:
The model doesn’t clearly show that gas exchange happens in the alveoli through the capillaries. The model can also be easily misinterpreted. Because the model doesn’t show where this gas exchange is taking place, it looks like the blood picks up oxygen, delivers it to the body, and then comes back and expels the carbon dioxide it collects. Clarifying that this gas exchange is taking place in the capillaries would eliminate this confusion.

The gravitational force between two objects will be very small, unless...
Group of answer choices
the objects are very far apart
the objects have very large masses
the objects are in the solid state of matter
the objects are spinning
Answer:
the objects have very large masses or an object in circular orbit. This has motion but its always being to pulled to earth by gravity.
Greater gravitational forces will be used to attract heavier things, since the gravitational force is directly proportional to the mass of both interacting objects. Two objects are attracted to one another by gravity as their respective masses increase. Thus, option B is correct.
What is the role of large masses in gravitation force?The gravitational pull between two objects changes inversely with their squared distance and directly with their large masses.
As a result, the gravitational force between the two items would decrease to one-fourth of its initial strength when the large masses of both objects are halved without affecting their distance.
Therefore, The objects are either in a circular orbit or have extremely large masses. Although something is moving, gravity is always bringing it dangerously close to the ground.
