Darwin observed many finch species on the Galapagos Islands. To explain these observations, he proposed that each species evolved from the same common ancestor, which was a finch species that migrated to the islands from the mainland. What additional evidence did Darwin use to support his explanation?
A. The finch populations were very numerous, and different species often bred with one another.
B. The finch species lived in different habitats on different islands, which isolated them from one another.
C. The finch species were distributed evenly among all of the islands, but did not interbreed.
D. The beaks of the finches were identical, allowing them to eat the same foods on any of the islands.

Plz plz plz help What processes allow continents to change location over time?
Group of answer choices
As the gravitational pull of the sun and moon fluctuate the continents are pushed or pulled in different directions which results in the movement of continents.
Plates are floating and sliding on the asthenosphere. After millions of years the plate movement allows continents to move.
Since the Earth is mostly water, plates can easily float to new locations.
Answer:
Plates are floating and sliding on the asthenosphere. After millions of years the plate movement allows continents to move.
Explanation:
Continents lie on tectonic plates that are constantly shifting, which eventually caused the continents to change location.

According to the CDC, is the flu vaccine safe and effective?
Need answer ASAP pls I’ll give brainiest
Answer:
any vaccine effectiveness can vary, recent studies show that flu vaccination reduces the risk of flu illness by between 40% and 60% among the overall population during seasons when most circulating flu viruses are well matched to the flu vaccine.
Explanation:
this is right i had to to a test and a whole lesson over this. ^^^^ that all is from my notes!
Yes, the flu vaccine is safe and effective according to the CDC.
The Centers for Disease Control and Prevention (CDC) recommends annual flu vaccination for everyone aged six months and older, with very few exceptions. The flu vaccine has been extensively studied, and the CDC and other health organizations have found it to be safe and effective in preventing flu infections and reducing the severity of illness for those who do get infected.
The flu vaccine is developed each year to protect against the most prevalent strains of the influenza virus that are expected to circulate during the upcoming flu season. It stimulates the body's immune system to produce antibodies against the virus without causing the flu itself. While the vaccine's effectiveness can vary from season to season due to changes in the circulating flu strains, it still provides significant protection and lowers the risk of severe complications and hospitalization.
As with any medical intervention, there can be some side effects, but they are usually mild and short-lived, such as soreness at the injection site or mild fever. Serious reactions to the flu vaccine are rare. The benefits of getting vaccinated far outweigh the risks, especially for high-risk groups, such as young children, older adults, pregnant women, and individuals with certain medical conditions.
Overall, the CDC and other health authorities strongly recommend flu vaccination as a safe and effective public health measure to protect individuals and communities from the flu and its potential complications. It is an essential part of flu prevention strategies and is encouraged for everyone to help reduce the spread of the virus and its impact on public health.

CROSSING OVER:
Crossing over is a unique process that occurs only during meiotic division. Crossing over, also called recombination, occurs during prophase I of meiosis. Crossing over is the process by which non-sister chromatids of homologous chromosomes (a pair of similar but non-identical chromosomes from each parent). Crossing over ensures genetic diversity in the gametes (daughter cells) produced from meiosis:MEIOSIS:
Meiosis is the type of cellular division employed by sexual reproducing organisms to create sex cells or gametes. Meiosis produces four genetically different daughter cells called gametes. Sperm cells are gametes produced by male organism while egg cells are gametes produced by female organisms.Learn more: https://brainly.com/question/18824252?referrer=searchResults

Who does not need a circulatory system?A single-celled organism that doesn't required the circulatory system as human do. Since they are the singular, they can interact with their environment directly. Oxygen need to be supplied by the circulatory system and some of the cells also well differentiated so it can be only accept a certain processed food.
Most mollusks, or except for the some particular cephalopos like skids, have an open circulatory system in which the circulating fluid has been called hemolymph that flows through the body thanks to the muscle contractions that pump this fluid into the hemolymph vessel that discharges this fluid into the body cavity allowing substances and gases to be exchanges between body cells and the carrying hemolymph. Then this fluid goes back to the blood vessel and reinitiates the circulation.

Answer:
DKPCOFGS is a mnemonic for: Domain, Kingdom, Phylum, Class, Order, Family, Genus, SpeciesHow does Earth’s position relative to the Sun cause the four seasons?
a. Earth orbits the Sun once a year and is in a different position with respect to the Sun every three months, resulting in four seasons.
b. The tilt of Earth’s axis with respect to its orbit changes back and forth approximately 46 degrees every six months, resulting in four seasons.
c. Earth’s axis is tilted with respect to its orbit, so, as it revolves around the Sun its tilt with respect to the Sun changes, resulting in four seasons.
d. Earth rotates on its axis every twenty-four hours, and, since the axis is tilted with respect to the Sun, different parts of Earth experience different day-lengths, resulting in four seasons
Answer:
c. Earth’s axis is tilted with respect to its orbit, so, as it revolves around the Sun its tilt with respect to the Sun changes, resulting in four seasons.
Explanation:
Earth’s tilted cause the four seasons in different parts of earth. In summer, the surface of earth is present directly to the sun causes high temperature of that region while on the other hand, the same region experience cold temperature in winter due to tilt of the earth which does not allow the solar radiation comes directly to that region of the earth that leads to cold temperature.
