This will lead to change in populations over generations in a process that Darwin called descent with modification. ... One of the best examples has been demonstrated in the very birds that helped to inspire Darwin's theory: the Galápagos finches.
a mechanism for evolution; all organisms are related through descent from an ancestor; descendants accumulated adaptations; descent of all organisms from an ancestor that lived in the past; descendants accumulated diverse modifications (adaptations)
if the first one doesnt work try the second
An example of descent with modification is a bacterium that inherits a gene for antibiotic resistance, has a more significant possibility of survival. Natural selection then applies that resistance through the population, forcing scientists to come up with a new antibiotic.
What is darwin's theory of descent with modification?Darwin described evolution as "descent with modification," the theory that species evolve over time, give rise to new species and transmit a common progenitor.
The means that Darwin proposed for evolution is natural selection.
Thus, a bacterium that inherits a gene for antibiotic resistance, is an example of descent with modification.

How would an organism most likely respond to extremely cold temperatures? (4 points)
A. Blood vessels would constrict to reduce heat loss through negative feedback.
B. Blood vessels would dilate to transfer heat to more areas of the body through positive feedback.
C. Cold receptors would signal the body to retain heat through positive feedback.
D. As the organism uses energy, body temperature would decrease through negative feedback.
Explanation:
the answer is A..........
An organism most likely would respond to an extremely cold temperature as the blood vessels would constrict to reduce the heat loss through the negative feedback. Thus, the correct option is A.
How does an organism adapt to cold temperature?Adaptations are the changes in the body of a living organism which help them to survive better in a particular set of environmental condition such as hot temperature, cold temperature, etc.
In cold temperature, Shivering is an adaptation in which the nerve impulses are sent by the hypothalamus of the brain to the skeletal muscles to bring about rapid contractions which generate heat and this helps the body in staying warm. Shivering therefore helps an organism in raising the body temperature. Increase in the metabolic rate, the liver produces extra amount of heat in order to raise the temperature of the body.
An organism most likely respond to cold temperature as the blood vessels constrict to reduce the heat loss through negative feedback.
Therefore, the correct option is A.

Which kind of organism is an autotroph? consumer producer decomposer herbivore
Answer:
Producer
Explanation:
An autotroph is a type of organism that is capable of producing its own food from inorganic substances. The correct answer is "producer."
Describe autotroph.Autotrophs utilize various processes to convert energy into usable forms. The most common and well-known method is photosynthesis, which involves capturing sunlight and using it to convert carbon dioxide and water into glucose (a type of sugar) and oxygen. Plants, algae, and some bacteria are examples of autotrophs that perform photosynthesis.
They are often referred to as producers because they can convert energy from sunlight (or other forms of energy) into organic compounds through processes like photosynthesis or chemosynthesis.
Autotrophs, such as plants, algae, and some bacteria, are able to synthesize their own nutrients and energy sources, typically using sunlight, water, and carbon dioxide. They form the foundation of food chains and provide energy for other organisms in ecosystems.
Therefore, the correct answer is "producer."

If the mrna is damaged, it directly interferes with the ability of a animal cell to do which of the following?
Answer:
Proteins.
Explanation:
If the mRNA is damaged, it directly interferes with the ability of producing proteins in animal cell because mRNA is responsible for carrying the protein blueprint from a cell's DNA to its ribosomes which are considered as the machines of the cell that produces proteins for the cell. These messenger RNA has the information about what type of proteins are required to produced for the cell. So if mRNA is damaged, the ribosomes are unable to produce proteins for the cell.

Explanation:
Mortality and emigration decrease the population. Thus, the size of any population is the result of the relationships among these rates. Natality, mortality, immigration, and emigration rates apply to every population, including the human population. The sum of these rates makes up the growth rate of a population.

Which statement describes the relationship between plants, animals, and the carbon cycle?
O Plants use carbon and release oxygen, and animals release carbon and use oxygen.
O Animals fix carbon and release oxygen, and plants release carbon and use oxygen.
Animals fix carbon through respiration, and plants fix carbon through photosynthesis.
Plants use carbon when they decompose, and animals release carbon when they decompose.
Answer:
Plants use carbon and release oxygen, and animals release carbon and use oxygen.
Explanation:
The statement that accurately describes the relationship between plants, animals, and the carbon cycle is:
Plants use carbon and release oxygen, and animals release carbon and use oxygen.
Why do plants use carbon and release oxygen?Plants play a crucial role in the carbon cycle through the process of photosynthesis. They absorb carbon dioxide (CO2) from the atmosphere and use it, along with sunlight and water, to produce carbohydrates and release oxygen as a byproduct. This process helps to remove carbon from the atmosphere and convert it into organic compounds.
On the other hand, animals (including humans) obtain energy by consuming plants or other animals. During respiration, animals take in oxygen and release carbon dioxide as a waste product. This carbon dioxide is then released back into the atmosphere, where it can be used by plants for photosynthesis.
Therefore, plants contribute to the reduction of atmospheric carbon dioxide levels by using carbon during photosynthesis and releasing oxygen, while animals contribute to the carbon cycle by releasing carbon dioxide during respiration and utilizing oxygen.

Mildred collects a sample of fossilized plant material. She takes it back to her lab to run some tests on it. Mildred is able to measure the amount of carbon-14 in her sample and compare this to the amount of carbon-12 in it. She uses this information to calculate that the fossil is 4,500 year old. The process that Mildred used is known as _______
Radiocarbon dating
Faulting
Indexing
Superposition
Explanation:
Radiocarbon dating is a process of determining the age estimates of various objects and materials using the radioactive properties of an isotope of carbon, carbon-14.
Radiocarbon dating uses the ratio of two isotopes of carbon, carbon-12 and carbon-14 present in materials which contains carbon to determine their age.
There is a fairly constant ratio of carbon-12 and carbon-14 in living organisms. However, at death, due to the decay of carbon-14 to carbon-12, the ratio begins to change. Since the rate of decay of carbon-14 is fairly constant, a property known as half-life, the time it has taken for carbon-14 to decay to carbon-12 can be calculated. This calculated time will givee the age of the fossilised material.

In the absence of oxygen, a yeast cell undergoes fermentation and uses 100 molecules of glucose. How much net ATP will be generated
Answer:
200 ATP molecules
Explanation:
Yeast is a fungus that undergoes fermentation instead of cellular respiration when there is an absence of oxygen. In the fermentation process undergone by yeast, which produces an alcohol as product (alcohol fermentation), two (2) ATP molecules are produced as net ATP.
However, if a yeast cell undergoes fermentation and uses 100 molecules of glucose, the yeast cell will generate a net ATP of 2 × 100 molecules = 200 molecules.
