Hello. It is not possible to access the website you are referring to, but I will try to help you in the best possible way.
Natural selection is the term created by Chales Darwin to compose a theory of biological evolution. According to this term, living beings that have characteristics favorable to their survival, in relation to the environment in which they live, are more likely to survive and pass these characteristics on to their descendants, while those that do not have these characteristics are more likely to die. .
An example of this can be seen in a population of lizards that live in environments with a lot of grass. According to natural selection, green colored lizards would have better advantages of surviving because they would be camouflaged in the grass and would not be seen by predators, unlike red lizards, which would be easily identified and captured by predators. therefore, the population of red lizards would decrease until it ceased to exist, while the population and green lizards would survive and generate other green lizards.

Answer:
The way to figure this this type of question out is card by card. So the first card in the second hand is 2 in 52 (It can match either of the cards in the previous hand). × 1 in 51 ( it has to match the card that was not matched by the first card and there are 51 choises left). So 2 in 52 = 1 in 26 x 1 in 51 = 1 in 26 x 51 = 1 in 1326

What are all the steps of DNA replication
Answer: Initiation, elongation, and termination. In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands

Answer:
the process when whereby organism better adapted to their tend to survive and produce more offspring
Answer:
The process in which animals adapt to the circumstances of the inhabited environment in order to survive.
Explanation:
In order for animals to survive, they must adapt and find ways to evade potential predators. This is why animals evolve and diverge from there original physical state in order to survive.

What are the causes of variations ? please explain thi also
Answer:
variation can be caused by mutation and other things
Explanation:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light or cigerette smoke
➜ Following are the causes of variations:
Dual percentage: Offsprings inherit some features from mother and some from father. Hence no offspring will exactly resemble to either of the parent or each other.Mutation in gene or chromosomal pattern also causes variations.Viruses contain a (blank), (usually a lipid membrane) and basic proteins.

Which results from the interaction of solar weather on Earth's magnetic field? Select the two correct answers.
A. geomagnetic storms
B. auroras
C. radiation belts
D. solar wind
Answer:
A & C
Explanation:
In short terms, A & C are the only answers that have anything to do with the magnetic field. Solar wind is part of solar weather, and is involved in the creation of the other three answers. Auroras are formed through the interaction of solar wind and the oxygen & nitrogen in Earth's atmosphere.
The geomagnetic storms and auroras are the results from the interaction of solar weather on Earth's magnetic field. The correct options are A and B.
What are solar weathers?Solar or space weather refers to actions that take place on the Sun's surface.
These reactions usually have different effects on our planet, owing primarily to the Earth's magnetic field, which acts as a shield for the planet.
A geomagnetic storm happens when the solar radiation collides with the Earth's electromagnetic field, causing disruptions in the magnetosphere.
The interaction of loaded solar particles and the land based electromagnetic field produces an aurora, which is a luminescent formation.
The solar wind transports these particles to the terrestrial electromagnetic field, in which they are shown in various colors depending on the type of particle.
Thus, the correct options are A and B.

How do weathering and erosion work together to change or build landforms
Answer:
Erosion is another geological process that creates landforms. When mechanical and chemical weathering breaks up materials on the Earth's surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. Plateaus can also be formed this way.

Complete the chart. Thymine _____, Guanine ____.
Answer: 27, 23
Explanation: Thymine goes with Adenine and together they equal 50 so Thymine would be 27 because Adenine is 23. Same with Cytosine and Guanine. They go together and equal 50 so Guanine would be 23 because Cytosine is 27. Hope this helps!

The immune response consists of different components playing their role for a common goal: to rid the body of a pathogen. Create an analogy that helps explain the roles of the responses of the immune system and describe the relationship between the responses.
Answer:
In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.
A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are produced in the primary response

Explanation:
When a system transforms energy from one type to another, the system always experiences
A
energy loss through heat.
B
energy gain through light.
C
mass gain through nuclear reaction.
D
mass loss through chemical reaction.
Answer:
A energy loss through heat
When a system transforms energy from one type to another, the system always experiences energy loss through heat. So the correct option is A.
What is meant by energy loss?Energy is lost when it is changed from one form to another, transported from one location to another, or transferred from one system to another. As a result, part of the energy intake gets transformed into an amorphous form of energy, such as heat, when energy is transformed into a new form.
Functionally, unless one is purposefully converting energy into heat, it is nearly hard to convert all of the energy input into the output energy (like in a heater).
The energy that enters power lines always outweighs the energy that exits at the opposite end of the power lines whenever electrical energy is transferred by power lines.
Processes are never 100% efficient because of energy losses.
As it travels, energy changes significantly and assumes a variety of forms. Every conversion it passes through results in some sort of energy "loss."
Even if this energy doesn't truly vanish, part of it changes into forms that we can't utilize or don't want to use. Therefore the correct option is A.

bacteriophages marked with phosphorus-32.
What did the investigators conclude from this result?
A. Bacteriophages inject DNA into the bacterial cells.
B. Bacteriophages inject protein into the bacterial cells.
C. Bacteriophages inject carbohydrates into the bacterial cells.
D. Bacteriophage absorb DNA from bacterial cells.
Answer:
i belive that it is option a
Explanation:
Hershey and chase experiment proving that DNA is the genetic material. When the bacterial cells were infected with the P 32 and on entry on DNA it showed the entry of DNA in the cells.
What is the full form of DNA ?The full form of DNA is deoxyribonucleic acid where it is the deoxyribose sugar combined with nucleotides with the phosphorous group.
Bacteriophages are the species which only pass on their genetic material inside and in the experiment it followed the same protocols as well where the radiolabelled DNA with P 32 showed entry in the bacterial cells.
Therefore, bacteriophages are the showing radioactivity when the phosphorous combined with P 32 got mixed and expressed inside the DNA .
