Which study type of natural selection did grants observe when studying the beak size of galápagos finches
Grants study the type of natural selection on break size of Galapagos finches.
Grant study on Galapagos?Peter Grant and Rosemary Grant studied Darwin's finches. They observed evolution by natural selection on Galapagos finches which occured during drought . Birds with bigger beaks tend to survived and reproduced because they adapt well and can eat different types of seeds at all sizes of seeds, whereas small-beaked birds could only eat small seeds. while birds with smaller beaks could not survive well.
Therefore, Grants study the type of natural selection on break size of Galapagos finches.

Forensic entomology identifies the fauna on a dead body to make predictions about the death. C) ants, mites, and beetles frequent the body 3-17 days after death.
What is forensic entomology?Forensic entomology is the forensic branch that studies the cadaveric fauna associated with a dead body to make scientific conjectures.
Cadaveric fauna usually includes different forms of invertebrate species and their stages of development. There is a predictable sequence in which different species arrive at the dead body and inhabits it, and this sequence depends on the time the individual has been dead and the decomposition state of the body.
The species inhabiting the body and their developmental stage can be used as significant data to estimate the time of death, the region, and the circumstances under which the individual died.
Stages of decomposition depend on the region, but we can make this generalization,
1-3 days ⇒ adult flies and eggs, and a few larvae
3-5 days ⇒ bacteria and other microorganisms act. The decomposing body produces gasses that inflate the carcass. Larvae penetrate the body, release the gasses, and the carcass collapses.
5-15 days ⇒ Maggots, flies, ants, and beetles have already reached the dead body.
15-25 days ⇒ Most flesh is already consumed, and the body is in the advanced stage of decay. Although the number of invertebrates is low, the diversity of species is great. There are carpet beetles, ants, skipper flies, and mites.
25-50 days ⇒ Almost dry body with no flesh. Some arthropods are still feeding on it.
>50 days ⇒ Bones
Note: Remember that these are approximations and might vary according to the region and environmental conditions, such as temperature, precipitation, humidity, etcetera.
According to this information, we can say that ants, mites, and beetles frequent the body in warmer climates between 3 and 17 days. Option C.

Sea otters are found primarily off the coast of California. They are one of the main predators of sea
urchins, Sea urchins feed on the roots of kelp beds, effectively killing large areas of kelp. Kelp beds
are important because they provide a safe location for several species of fish to spawn and hatch
their offspring. Data suggests that sea otters are a keystone species in their ecosystem.
What will most likely happen to this ecosystem if sea otters are permanently removed?
ОА.
OB.
Other species will evolve the ability to eat sea urchins, keeping the urchin population
under control.
The sea urchin population will rapidly increase, resulting in less kelp and a decrease
in biodiversity.
Sea urchins will assume the role of keystone species, allowing the ecosystem to remain
balanced,

Cactus finches have long, pointed beaks. Say the only source of food for Cactus finches is cactus flowers. If a plant disease killed a large portion of the cacti on the Galapagos islands, how would the population of Cactus finches change
The population of the Cactus finches suddenly experiences a decline when a large portion of the cacti on the Galapagos islands was killed by a disease.
What do you mean by Population?A population may be defined as the number of individuals of the same species living in a particular area at a given time.
Cactus finches only depend on the cactus flower as a food source, and if these flowers were killed by a disease, the cactus finches do not get enough food to survive and reproduce, hence their population may fall rapidly.
Therefore, the population of the Cactus finches suddenly experiences a decline when a large portion of the cacti on the Galapagos islands was killed by a disease.

what is the difference between mitosis and cytokenisis
Answer:
Mitosis refers to the division of a cell's nucleus into two. Cytokinesis refers to the further division of the cytoplasm of the cell, forming two daughter cells.
Explanation: I hope this helps :)
Explanation:
The Mitosis Phases
Mitosis itself is the division of the nuclei into daughter nuclei. It includes five phases of its own.
Prophase: Here, chromosomes become more condensed in the nucleus, and the nuclear membrane dissolves. The mitotic spindle forms from the centrioles, which have split and moved to opposite poles (sides) of the cell. This spindle is made of proteins in the form of microtubules.
Prometaphase: In this step, the chromosomes migrate toward the center of the cell. They are propelled by the mitotic spindle apparatus attached at the centromeres that joins sister chromatids. They begin to approach a line perpendicular to the direction they are moving, through their centromeres, called the metaphase plate.
Metaphase: In this step, chromatids align precisely along the metaphase plate via their centromeres, with one sister chromatid on each side of the metaphase plate.
Anaphase: In this step, the sister chromatids are pulled to opposite poles of the cell, releasing from each other at the centromere. The spindle fibers, again, are responsible for this motion.
Telophase: In this step, daughter nuclear membranes form around the newly formed daughter nuclei. At this point, chromatids are unpaired, as this generation's chromosome replication has yet to start. This is because cell division is not quite complete.
Cytokinesis
To define cytokinesis as a stand-alone phase, the difference between telophase and cytokinesis is best imagined by thinking of telophase ending the instant both daughter nuclear membranes are completely formed. Cytokinesis starts with a "pinching inward" from the top and the bottom of the cell, with one daughter nucleus on each side.
This "pinching" results from the formation of a protein structure called the contractile ring, which runs around the widest part of the cell under the membrane. When this shrinks inward, it pulls the membrane tighter along with it until the cell halves are completely separated by the now-finished "pinch."
