Based on fossilized evidence, there are scientific claims made about the evolution of certain species. If a scientist studying the fossils of a specific species had a hypothesis other than what was currently accepted, what steps should be taken to have the alternative hypothesis considered
Answer: For the scientist to have alternative hypothesis considered, it is imperative he takes certain steps, this steps will ascertain the scientific claims already made about the evolution of species.
Therefore,the scientist will simply test the alternative hypotheses inorder to know that they are incorrect.
This testing of hypotheses to ascertain their incorrectness is very useful in the study of fossils.
Dump out half of the particles. Place your hand tightly over the top and shake the container. Then remove most of the remaining particles, and shake the container again. Compared with the full container, which states of matter do these two models most closely represent? Explain.
Answer:
solid
Explanation:
The two models explained are most closely representing the "solid" state.
As in both the models the techniques used are to separate particles through shaking technique and shaking is efficient gravity separation method which helps in separating solid particles such as while dealing with tungsten and tin.
Hence, the correct answer is "Solid".
Answer:
When the container was half full, the particles had more freedom to move around than they did when the container was full. A half-full container represents a liquid. When the container had only a few particles, they had lot more freedom to move about. So, this model represented a gas.

Without the discovery of magnetic reversals recorded on the ocean floor, scientists
A. could not confirm the usefulness of sonar
B. could destroy the hypothasis of continental drift
C. could not provide a mechanism for moving continents
D. could explain how the seafloor was being destroyed
Answer:
C. could not provide a mechanism for moving continents
Explanation:
Magnetic reversals have the habit of causing geological displacements, since they are directly linked to the movements and distribution of tectonic plates on the planet, which are responsible for the movements of the continents. In this case,
if the discovery of magnetic reversals recorded on the ocean floor were not carried out, it would be impossible to establish its relationship with the movement of the tectonic plates, making it impossible to provide a mechanism for moving continents.
What has a greater influence on protein levels? A. Protein degradation has a greater influence because they are denatured faster than the cell can produce them B. mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced C. mRNA destroyer concentration has a greater influence because mRNA is destroyed right after the proteins are produced D. Protein degradation has a greater influence because outside factors like antibiotics can cause it, and it is difficult to recover from
Answer: b
Explanation: i got the answer wrong and i’m looking at the results rn
Protein is being produced with the help of a process called translation in which mRNA gets translated to produce proteins. The translation is followed after the process of transcription of DNA to RNA.
The cause of the greater influence of protein levels has defined as follows:
The destruction of mRNA could greatly influence protein levels as mRNA is considered the source for proteins to get synthesized. This is because if mRNA gets destroyed, proteins would not have been produced at all. Thus, directly influences the levels of protein.
Thus, we can conclude that mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced. Hence, option (b) is the correct answer.

Answer:
D. Gly Lys Cys
Explanation:
2) Micah and Taylor investigate the effect of tap water and spring water on the growth of plants.
They grew two plants of the same type and size in separate containers. Every three days, they
added the same amount of tap water to one plant and the same amount of spring water to the
other. Describe an action that would best improve the reliability of their results?
Answer:
To improve the reliability of the results, the nutritional component of each category of water must be tested and recorded.
Second, the experiment should be carried out under greenhouse conditions.
The above actions will afford more control. When an experiment is controlled, it means that except for the dependent variable, all other variables are kept constant by the scientist.
By performing the experiment under greenhouse conditions, the kind of water the plants receive, temperature and other biotic actors are kept within measurable limits thus increasing the reliability of the results.

When you centrifuge the DNA isolated from the bacteria, the DNA separates into two classes. One class of labeled DNA includes very large molecules (thousands or even millions of nucleotides long), and the other includes short stretches of DNA (several hundred to a few thousand nucleotides in length). Which two classes of DNA do these different samples represent
Answer:
Leading strand and Okazaki fragments
Explanation:
The two classes of DNA that the different samples represent include the leading strand and the Okazaki fragments.
The large molecules DNA with thousands/millions of nucleotides constitutes the leading strand of the DNA while the short stretches of DNA with just a few thousand nucleotides in light constitute the Okazaki fragments.
This is because, during replication, the leading strands of DNAs are usually synthesized in a continuous manner and end up forming a long, continuous daughter strand while the lagging strands are usually synthesized in short, discontinuous fragments known as the Okazaki fragments.
The continuous/discontinuous replication of the leading/lagging strands of the DNA is due to the characteristics of the enzyme responsible for adding bases to the growing daughter strands. The DNA polymerase enzyme can only add nucleotides in the 5' to ' direction.

That is, it can itself have a separate layer of base membrane?
Answer:
"Podocytes are cells in the Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus. Podocyte cells make up the epithelial lining of Bowman's capsule, the third layer through which filtration of blood takes place.[1] The Bowman's capsule filters the blood, retaining large molecules such as proteins while smaller molecules such as water, salts, and sugars are filtered as the first step in the formation of urine. Although various viscera have epithelial layers, the name visceral epithelial cells usually refers specifically to podocytes, which are specialized epithelial cells that reside in the visceral layer of the capsule.

If a cell has 24 pairs of chromosomes in its diploid state, how many
chromosomes will it have after Meiosis 2?
A. 12
B. 24
C.48
D. 6
Answer:
option A is correct that is 12
Explanation:
meiosis occur in two phases in first phase DNA replication occur and amount of DNA become doubled without any change in the chromosome number and two daughter cell (each 2 n)are formed.
now in stage 2 each daughter cell undergoes mitosis with the formation of two cells with half chromosomes(n)
now 2n=24
n=24/2 =12
after meiosis stage 1...........two daughter cell each with 24 chromosomes
stage 2 .............each daughter cell form two grand daughter cell each with 12 chromosomes
net result.......4 daughter cell each with 12 chromosome(assuming cell as a diploid cell)
If a cell has 24 chromosomes before cell division then the daughter cell resulting from the mitotic division will have 24 chromosomes while the daughter cell resulting from the meiotic division will contain 12 chromosomes each.
The answer is option A.
What are meiotic and mitotic cell divisions?There are sorts of cell departments: mitosis and meiosis. most of the time whilst humans discuss “cellular division,” they suggest mitosis, the procedure of making new frame cells.

Scientists are able to reproduce certain plants and animals by cloning them in laboratories. The diagram shows the steps of cloning using tissue cultures. Do you think cloning is a form of asexual reproduction? Explain your answer using evidence from the diagram
Answer:
Yes.
Explanation:
Yes, cloning is a form of asexual reproduction because there is no fusion of sperm and eggs takes place. the animal which is formed from this process is identical of that organism because it is produced from the tissue of that single animal. in 1996, first mammal is produced from cloning was sheep named dolly at the Roslin Institute in Scotland. In cloning, the egg is taken from female organism and remove the nucleus from the egg then the desired organism cell is taken and fuse with the nucleus with the help of electricity. Then implant this embryo in the body of first organism from where egg is taken and after that the embryo turns into a baby, this process is called cloning.
Answer:
Yes, cloning is a form of asexual reproduction. The diagram shows that new plants form from a single parent plant, which means that the offspring are genetically identical to the parent.

Answer: Option C.
slight fluctuations that are kept within a narrow range.
Explanation:
An invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have slight fluctuations that are kept within a narrow range so has to maintain homeostasis and prevent the cells of the the invertebrate from not shrinking which can be due to the salt solution (Hypertonic).
Estuary is an area of water or shorelines where river meet the ocean. It normal do have concentration of salts. Organisms that live in estuaries must be able to adapt to their dynamic environments, wich is due to variations in water chemistry includes salinity, as well as physical changes like the rise and fall of tides.
