What trait variation did Charles Darwin observe after studying the Galapagos finches? (5 points)
How did Darwin explain the differences in traits? (10 points)

Answers

Answer 1

The finches of the same genus had different characteristic on the different islands of the Galapagos. They had different graded beaks sizes and shapes. In some islands, finches had sharp beaks for stabbing their prey. In other islands, the fiches had short stout beaks for grain-eating. This is a case of allopatric speciation where a population of the finches diverged to.adapt to the habitats in the different islands and also claim different niches






Answer 2

There where 3 different variations of the Galapagos Islands. We'll call them flocks X, Y, and Z. All of them eat fruits, seeds, and insects, but they have their own preferences. Flock X has sharp, piercing beaks that good for catching bugs and eating soft fruit, but they will also eat seeds. Flock Y has hard, spoon-like beaks that are good for breaking seeds, but they will also eat insects and fruits. Flock Z has short beaks that are good for catching insects, but will also eat fruits and seeds.

What is the main difference between the central nervous system (CNS) and the peripheral nervous system (PNS)?

Answers

The Central Nervous System (CNS) includes all of the nerves of the Brain and Spinal Cord.

The Peripheral Nervous System (PNS) includes all of the nerves both sensory and motor connecting the CNS to the muscles, organs, and sensory structures of the body.

Answer:

CNS includes the brain and spinal cord which analyze sensory inputs, whereas PNS consists of neurons and nervous tissues that carry the information.

Explanation:

The nervous system has two distinct main parts - the peripheral nervous system (PNS) and the central nervous system (CNS).

CNS contains the spinal cord and the brain serves the nervous system's command center. the spinal cord and the brain analyze sensory inputs what it exactly means and quickly orders the body parts that time to move faster.  

PNS consists of the nerves, which leave the brain and the spinal cord and travel to evident regions of the body. The main job of PNS is to send information collected by the sensory receptors to the CNS.

How dose science influence the decisions made about social, economic, and political issues?

Answers

This is a rather subjective question and has a lot to do with the type of society in which one lives. the more secular the world is becoming... gives science a huge spotlight on the stage. because science provides an answer with tons of evidence to back it up, it is seen as a reliable method to follow. So, socially speaking you may have experienced in a normal conversation where someone turns around and tells you that your opinions are just opinions and have nothing factual to back them up. This is where science comes in. Economically and politically speaking, science is used to justify different political aims of governments. However, this is done mostly through the misrepresentation of science by people who are trying to pursue their own agenda. So really this question can be answered in many ways and from many different perspectives but do not forget that science influences all streams for the better but also for the worse in the way in which it is represented.

virus life cycles help please! fill in the blank diagram.

Answers

im not quite sure but i think you should go on google and check it out you will definitely find the answer there

Answer:

The virus life cycle consists of 6 stages:

1. Attachment: The protein on the virus capsid attaches itself to the receptors on the ell surface of the host.

2. Penetration: The viruses capsid goes through a conformational change, fusing the virus to the host's cell surface.

3. Uncoating: The virus nucleic DNA is released when the enzymes of the virus or host degrade the capsid of the virus.

4. Replication: Once released the virus DNA undergoes transcription or translation. The replication will be different due to the type of virus invading the host, example DNA virus, RNA virus or viruses with opposite nucleic acid polarity.

5. Assembly: Maturation process occurs, where by the replicated DNA and the virus protein are packed into virions in order to be released from the host.

6. Virion release: The virions can be released either through lysis or budding.

Why does extracted chlorophyll fluoresce under UV light while chlorophyll inside intact chloroplasts does not?

Answers

Chloroplast is what gives the plant color, while chlorophyll is what reacts during chemical reaction.

Final answer:

Chlorophyll inside intact chloroplasts does not fluoresce under UV light because it is shielded from direct UV exposure by other cellular components. However, extracted chlorophyll fluoresces under UV light due to the absence of shielding elements.

Explanation:

Fluorescence is the emission of light by a substance after it absorbs photons of higher energy. Chlorophyll inside intact chloroplasts does not fluoresce under UV light because it is shielded from direct UV exposure by other cellular components such as thylakoid membranes. However, when chlorophyll is extracted from chloroplasts and exposed to UV light, it fluoresces because there is no longer any shielding element present.

an animal carcass had 24 grams of carbon 14 when it was alive and 3 grams when its fossilized remains were discovered how old is the fossil?

Answers

The carbon 14 left from this animal is 3 grams of 24 grams which is: 3g/24g= 1/8 times of its original mass. Then, the age of the animal fossil would be:

final weight= initial weight * (1/2) ^ time/half-live
1/8 initial weight = initial weight  * (1/2) ^ time/half-live
log2 1/8= log2 (1/2) ^ time/half-live
-3= -time/half-live
time= -3 * -(half-live)
time= 3 half-live

If the half-live is 5730 years, the age would be: 3* 5730= 17.190 years.

Moles are rodents very similar to mice. They typically live underground, spending most of their lives below the earth's surface. Mice, on the other hand, may dig burrows to nest and sleep in, but they spend much of their time above ground. Their nests can be made of cloth, hair, and hay. Because moles live underground, they have developed differently than mice

Final answer:

Rats belong to the group known as rodents, distinguished by their distinctive pair of continuously growing incisors used for gnawing.

Explanation:

To what group do rats belong? Rats, along with mice, beavers, and squirrels, are part of a group known as rodents. Rodents are characterized by their gnawing behavior, which is facilitated by their unique dental structure. They have a single pair of continuously growing incisors in both the upper and lower jaws that must be kept short through gnawing. This differentiates them from other mammalian groups, such as lagomorphs (including rabbits and hares), carnivores (such as cats, dogs, and bears), and insectivores (such as moles and shrews).

The biological classification of rats is important as it helps in understanding their behavior, evolutionary history, and their role in ecosystems. Additionally, recognizing the differences between various animal groups, such as rodents and insectivores, is essential for scientific studies related to embryology, conservation, and pest control.

describe the productions of protein through transcription and translation

Answers

Genes provide information for building proteins. They don’t however directly create proteins. The production of proteins is completed through two processes: transcription and translation. Transcription and translation take the information in DNA and use it to produce proteins. Transcription uses a strand of DNA as a template to build a molecule called RNA. The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein building machines. Through transcription the sequence of bases of the DNA are transcribed into the reciprocal sequence of bases in a strand of RNA. Through transcription the information of the DNA molecule is passed onto the new strand of RNA which can then carry the information to where proteins are produced. RNA molecules used for this purpose are known as messenger RNA (mRNA). A gene is a particular segment of DNA. The sequence of bases in for a gene determines the sequence of nucleotides along an RNA molecule. Only one strand of a DNA double helix is transcribed for each gene. This strand is known as the ‘template strand’. The same template strand of DNA is used every time that particular gene is transcribed. The opposite strand of the DNA double helix may be transcribed for other genes. During translation, the information of the strand of RNA is ‘translated’ from RNA language into polypeptide language i.e. the sequence of nucleotides is translated into a sequence of amino acids.

Give TWO advantages that cells gain by storing energy in the form of ATP.

Answers

1- it can be used when needed
2- it can be stored for a long time

Final answer:

Cells store energy in ATP to safely manage energy without increasing cell temperatures and to provide consistent amounts of energy for cellular processes, ensuring efficient cellular growth and function.

Explanation:

Cells gain two main advantages by storing energy in the form of adenosine triphosphate (ATP). First, ATP allows cells to store energy safely and efficiently, preventing the detrimental increase in temperatures that would occur if energy were stored as free energy. This is crucial because excess heat can denature enzymes and destroy the cell's structural integrity. Second, ATP serves as a uniform energy currency for the cell, releasing consistent amounts of energy upon hydrolysis of its high-energy phosphate bonds. This consistency is vital for the myriad of biochemical processes required for normal cellular growth and function, as it ensures that energy is distributed as needed without destabilizing the cell's environment.

energy gained

Compare and contrast inbreeding and hybridization

Answers

Final answer:

Inbreeding is the mating of closely related individuals within a population, while hybridization involves mating between different species. Inbreeding can lead to a decrease in fitness and reduced crop yield. Hybrids can be less fit or more fit than the parents, driving divergence or fusion between species.

Explanation:

Inbreeding is the mating of closely related individuals, such as siblings or cousins, within a population. It often leads to a decrease in fitness and can cause inbreeding depression, which is a decline in the overall health and vigor of the population. Inbreeding can be a problem in open breeding systems, like crop species, where it can result in reduced crop yield.

Hybridization, on the other hand, involves mating between individuals of different species to produce hybrid offspring. The fitness of hybrids can vary. In some cases, hybrids are less fit than the parents, and this can drive further divergence between the two species. However, hybrids can also be more fit, which can lead to fusion of the two species back into one.
