Answer: Beaks---->Evolution, Natural Selction, Genetic Drift, Behavioral Isolation, n Non-random mating...
Explanation:
Darwin observed many discoveries like the Galapagos tortoises, iguanas, penguins, crabs, etc...But one of the most important ones that definitely helped to see the evolution and the process of natural selection is the Galapagos finches they changed a lot mainly because of environmental changes. The Galapagos Islands are special to evolutionary history firstly because there are a lot of different sizes and colors in birds but the main focus was that after Earth was a Pangea, all land united, genetic drift occurred in the Galapagos island meaning that a small population was 'trapped' inside with no way of getting new traits though that's not exactly right because we not only change genetically but also by environmental changes and humans change it too of course(like hunting). Another important discovery that was found there wasn't only hints of evolution and natural selection but also behavioral changes especially in mating, some birds sing or dance it really depends but if some animals don't mate then new species are formed that's one of the reasons why it created a lot of diversity; Another reason to the topic of reproduction is non-random mating, some organisms are looking for some specific location or phenotypes in their mates if they don't find it they look for them in their own species which can cause the extinction of that species or spread it.

Which organisms were the least numerous? Why? (In a forest environment!)
Answers
Because top consumers have less energy than producers, there is only enough food for a few top level consumers, but there is plenty of food for herbivores lower down the food chain.
What is forest ecosystem?Forest ecology is the scientific study of forest patterns, processes, flora, fauna, and ecosystems. Forest management includes forestry, silviculture, and forest management.
The existence of all species in the forest in a well-balanced and environmentally friendly manner is the function of the forest ecosystem.
Forest ecosystems are classified as boreal, temperate, or tropical rainforest ecosystems.
The transfer of energy from one trophic level to the next, up the food chain, is shaped like a pyramid, with the base being wider and the top being narrower.
Because of this inefficiency, there is only enough food for a few top-tier consumers, but plenty for herbivores lower down the food chain.
Thus, top consumers were the least numerous.

Most successful parasites, such as a cat flea, weaken their host but do not kill it. Why is killing its host usually disadvantageous for a parasite?
Question 4 options:
Relatives of the host would then attack the parasites.
Lysosomes from the host would then attack the parasite.
If a parasite kills its host, it will then have to find a new host in order to survive.
Parasitism is a relationship where both organisms benefit; killing the host is not beneficial to the host.
Answers
Answer:
The correct answer is - If a parasite kills its host, it will then have to find a new host in order to survive.
Explanation:
Parasites are organisms that depend on other organisms for their food and energy in order to survive. The organism that they depend on is called their host. In this only parasites get benefitted while hosts are harmed.
Although parasites harm their hosts, parasites tend to not kill the host as its best for them so they do not have to find another host and again establish control on the host's body and body functions, for their survival.

As the nutritional energy passes through the food chain, energy......
O a) is gained
b) decreases
c) remains constant
d) increases, then decreases
Answers
Answer:
B. Decreases
Explanation:
In an ideal food chain, nutritional energy from producers (plants) are transfered to other animals at different levels on the food chain. As nutritional level is being passed from one level to another, most of the nutritional energy is lost in the process. Therefore, energy decreases as the nutritional energy passes through the food chain.
The figure above depicts the DNA-protein complex that is assembled at the transcriptional start site of gene X when the expression of gene X is activated in liver cells. Previous studies have shown th gene X is never expressed in nerve cells. Based on the diagram, which of the following most likely contributes to the specific expression pattern of gene X?
A.Expression of gene X produces large amounts of tRNA but undetectable amounts of mRNA.
B The general transcription factors inhibit the activation of gene X in liver cells by blocking the activator from binding to RNA polymerase II.
С The activator is a sequence-specific DNA-binding protein that is present in some tissues but not in other tissues.

What is gene expression?Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.
Because a particular protein can only be made when its gene is turned on, gene expression is significant.
However, there are several steps involved in translating a gene into a protein, and one of these steps—the creation of proteins—is crucial in the gene expression pathway that can be changed in cancer.
According to the diagram, the activator is a DNA-binding protein that only binds to certain sequences in select tissues.
Thus, the correct option is C.

Explanation:
Science is a discipline that studies the establishment of facts, principles and methods through experimentation and instills processes of investigations to learners. Making stuff with mud can be used to establish facts and principles e.g clay soil has smooth and fine particles and has high adhesive forces of attraction with water and hence will make longer and thinner ribbons while sand has large rough particles which make large and chubby (I couldn't think of another word) ribbons due to the weak adhesive forces between the particles and water.

When waves of light (and other electromagnetic radiation) come into contact with a surface or other boundary that does not absorb the radiation's energy, the waves bounce off the surface and back into space.
What is Light wave?The simplest instance of visible light reflection is a smooth pool of water's surface, where incident light is orderedly reflected to provide a clear image of the landscape around the pool.
When you throw a rock into a pool, it disturbs the water and causes waves, which prevent reflection by spreading the light rays in all directions.
The incoming light wave is referred to as an incident wave, and the wave that is bounced away from the surface is termed the reflected wave. Visible white light that is directed onto the surface of a mirror at an angle (incident) is reflected back into space by the mirror surface at another angle (reflected) that is equal to the incident angle, as presented for the action of a beam of light from a flashlight on a smooth.

Atoms of carbon-14 are radioactive. They decay into atoms of the element nitrogen. Suppose that a sample of rock is taken from a fossil. The sample has 1000 atoms of carbon-14 and 1000 atoms of nitrogen.
If carbon-14 has a half-life of 57-- years, how old is the fossil?
A. 11,400 years old
B. 5700 years old
C. 2850 years old
D. 17,100 years old.
Answers
The half life of carbon -14 is 5730 years. The carbon -14 undergoes decays to form nitrogen -14. 1000 atoms of nitrogen is formed from 1000 atoms of carbon. Hence carbon -14 decayed from 2000 atoms to 1000. Therefore it is decayed by one half life and the age of the sample is about 5700 years or more accurately 5730 years.
What is radioactive decay?Unstable radioactive isotopes of atoms undergo spontaneous nuclear decay by the emission of charged particles such as alpha or beta. The time required to decay half of the initial amount of the isotope is called half life.
Carbon -14 undergo beta decay and the nuclear reaction is given as follows:
[tex]\rm _{6} ^{14}C \rightarrow _{7}^{14}N + _{-1}^{0}e[/tex]
Thus, one carbon atom is converted one nitrogen atom. Hence, 1000 nitrogen atoms are formed from 1000 carbon atoms. The remaining number of carbon atoms in the rock sample is 1000. Thus, the initial amount was 2000.
The half life of carbon -14 is about 5700 years. Hence, it takes 5700 years to decay from 2000 to 1000 atoms. Therefore, option B is correct.
