Answer:
Explanation:
In 1855 Virchow published a statement based on his observations Omnis cellula e cellula, which means that all cells arise from pre-existing cells. This was not a new theory.
How would you
change the hypothesis if mussels died in
both aquariums?
The new hypothesis could be that there is another alternative factor that is negativey afecting dwarfs survivorship.
The previous hypothesis of high levels of phosphate killing mussels is not necessarily disproved. But the death of mussels from both the control and the treatment groups might be related to one of the controlled variables that could be actually afecting them.
----------------------
Probably different levels of phosphate are also affecting invididuals´ survivor rates. However, the fact that mussels from all the aquariums died suggests that there is something else going on that caused the death of all the individuals.
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment. Individuals of the control group are selected from the same population as the treatment group. These two groups are identical in all aspects except for the independent variable, which changes in the treatment group but remains constant in the control group.
We know that mussels in this experiment were taken from the same population and grown under the same controlled conditions. Only the treatment group received phosphate, but all mussels died, not only the ones that receive phosphate. This result turns to be useful because it is indicating that there is another variable that is killing mussels. Phosphate might be a cause of death, but there is also something else. So the researchers should pay attention to the controlled variables, such as water quality, temperature, pH, food supply, light exposure, or others.
These variables might be reflecting the real conditions under which mussels live. The results tell that one of these is related to individual death and could be a consequence of climate change or soil use, among other causes.

What is the effect of these currents on Earth's temperatures?
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
Why did the White House experience water damage ?
1.
It is made of granite which is strong.
2. It is made of sandstone which is very porous and is easily penetrated by rainwater
3. It is made of non-porous sedimentary rock
The White House building is made of sandstone which is very porous as a result water is easily penetrated inside it which causes damage and make the walls of building weak.
The White House is made of gray-colored sandstone that is brought from quarry in Aquia, Virginia. The north and south porticos of white house building are constructed with red Seneca sandstone brought from Maryland. These sandstones are porous in which rainwater is easily penetrated in it that cause damage to the white house building so it is concluded that the building is made of porous sandstone.

Fill in the bottom line of DNA with the complementary base pair:
Answer: ACCTGATCGTAGCT
Explanation:
Keep in mind that in DNA replication, the matching base pairs are A and T (adenine and thymine) and C and G (Cytosine and Guanine). This means that for DNA complementary strands, A's can ONLY bind with T's and C's can only bind with G's , and vice versa. So, your answer for the picture you have given is ACCTGATCGTAGCT

What are amino acids?
Amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life.
The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. There are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

The nucleus of the cell is similar to the_______ system of the body.
The nucleus of the cell is similar to the Neurological system of the body.
What is Nucleus?According to the Cell Biology, nucleus may be a membrane found in organism cells.
The nucleus contain all of the cell's ordering except mitochondrial DNA and in plant cell, Plastid DNA.
Nuclear DNA is organized as multiple long linear molecules in a very complex form with a large variety of proteins, like histones, to make chromosomes.
The nucleus maintains the integrity of sequences and controls the activities of the cell by regulation gene expression—the nucleus is, therefore, the control center of the cell
The nucleus contains nearly all of the cell's polymer, enclosed by a network of fibrous intermediate filaments and enveloped in an exceedingly double membrane referred to as the "nuclear envelope".
The nuclear envelope separates the fluid within the nucleus, referred to as the living substance, from the remainder of the cell. The scale of the nucleus depends on the scale of the cell it's contained in, with a nucleus usually occupying 8% of the whole cell volume.
The nucleus is the largest organelle in animal cells.
For example- In mammalian cells, the average diameter of the nucleus is approximately 6 micrometers (µm).
What is Neurological System or Nervous System of the body?The Nervous system could be a extremely advanced a part of associate degree animal that coordinates its actions and sensory data by sending signals to and from completely different components of its body.
In vertebrates it consists of 2 main components, the central system (CNS) and therefore the peripheral system (PNS). The CNS consists of the brain and neural structure.
The function of the system is to send signals from one cell to others, or from one a part of the body to others and to manage the body.
It will this by extracting data from the setting exploitation sensory receptors, causing signals that encrypt this data into the central system, process the data to work out associate degree applicable response, and causing output signals to muscles or glands to activate the response.

Two organisms, AABBCCDDEE and aabbccddee, are mated to produce an F1 that is self-fertilized. If all of these genes are on the same chromosome, and there is no recombination, how many different genotypes will occur in the F2
Answer:
2 genotypes: AABBCCDDEE; aabbccddee
Explanation:
The law of segregation (also called Mendel's First Law) describes how genes on different chromosomes segregate into gametes independently of each other. Moreover, recombination (also known as crossing over) is the interchange of genetic material between non-sister chromatids during meiosis. In this case, the five genes are on the same chromosome (i.e., they are linked together and do not segregate) and there is no recombination, thereby they are inherited as a haplotype block to the next generation:
- Genotypes parental (P) lines: AABBCCDDEE; aabbccddee
- Cross P1: ABCDE X abcde
- Genotype F1: AaBbCcDdEe (100%)
- Gametes F1: ABCDE; abcde
- Genotypes F2: AABBCCDDEE; aabbccddee (ratio 1:1)
A 55-year-old male is sent to your office to have an esophagogastroduodenoscopy. He is a heavy drinker and smoker who also consumes spicy foods on a daily basis. He is quite anxious about having the procedure performed and is afraid he might choke during insertion of the scope. His father and younger brother were both diagnosed with esophageal cancer. His father died, but the brother was just recently diagnosed and is taking chemotherapy.
A. List the risk factors the patient has for developing esophageal cancer.
B. How might you calm the patient's fears about the procedure?
Answer and Explanation:
A. The risk factors for this patient are age, family history, and smoking and alcoholism. That's because, most cases of esophageal cancer are detected at age 55 years. We must not forget that cancer is a disease with great genetic potential, which means that, as the father and brother of this patient had this type of cancer, this patient has a high probability of developing the same cancer. Furthermore, the constant consumption of cigarettes doubles the risk of developing esophageal cancer. This risk is also increased by alcoholism.
B. To calm the patient down, I would say that there is a very small and almost non-existent risk that he will choke or even feel the endoscopy insertion, as the entire procedure is done with the patient anesthetized and sedated.
A) Risk factors include
People between the age of 45 and 70 have the more risk of esophageal cancer.If the patient has genetic signs of cancer from the past generations may have highest risk of esophageal cancer.Males have more risk than women that is 3 to 4 times to develop esophageal cancer.Alcohol consumption also increases the risk of esophageal cancer.Too much weight or obesity increases the risk of esophageal cancer.Deficiency in nutrients, vitamins and minerals can increase risk of esophageal cancer.B) Calming the patients fears
Make the patient be happy and stress free.Do exercise which produces mood boost endorphins that get rid of worries and stress.Stay positive, being friendly keep good health.For more information on esophagogastroduodenoscopy, visit

One of the great mysteries of our Solar System is why Uranus is tilted on its side. Surely, if the solar system formed from the same rotating cloud of dust and gas, then all the bodies within it should rotate in the same way. And yet Uranus’ axis of rotation lies at 97 degrees to the plane of the solar system.
