Answer:
The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.
Explanation:
Factors that affect evolution.
As per the question the evolution is a gradual process that includes the changes in the body of the organisms thereby making them more stronger and dynamic than others. The 4 features that affect evolution are mutations, natural selection, genetic drift, and gene flow.
The answer is thus are a major factor that leads to evolution in specie.
As per the case, Grants studied his works of natural selection. As per the changes associated with the environment, the large beak was an advantageous trait that was favored by natural selection. This leads to the increase in the size of the finches and the decline of other properties. Such a beak size, color, and even behavior. Hence the four-factor to consider are genetic drift, natural selection, adaptation and mutation (evolution).Learn more about the four factors.

“The movement of cytoplasm is due to the movement of chloroplasts in the living cells of onion plant”, “while the movement of chloroplasts is due to the movement of cytoplasm in the living cells of bean plants”
which statement is correct and which one is wrong
''The movement of chloroplasts is due to the movement of cytoplasm in the living cells of bean plants'' is the correct statement.
The above statement is correct because chloroplast is an organelle which moves in the cell through the medium known as cytoplasm. Cytoplasm is a thick fluid that fills every type of cell and organelles are floating as well as suspended in this fluid.
All organelles such as the nucleus, endoplasmic reticulum, chloroplast and mitochondria etc are located in the cytoplasm. The portion of the cytoplasm except the organelles is called cytosol so we can conclude that chloroplast is an organelle which moves within the cell with the help of cytoplasm.

One property of a senescent cell is that it can no longer divide.
Senescent cells are cells which help in tissue development in an embryo and also helps to promote healing of injuries.
These cells however exhibit a very a large lysosomal activity which destroys
vital components in the molecules . This thereby prevents the senescent

Which of the following is not a lipid?
Asteroid
B cholesterol
C
wax
D cellulose
Answer:
cellulose
Explanation:
lipids are fats oils or waxes. cellulose is a fiber
Answer:
cellulose
Explanation:
Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein. Therefore waxes are not the answer.
Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings. Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts. Therefore steroid and cholesterol is not the answer.
Does hot water tend to rise or sink? Explain.
Answer:
When fluids (liquids and gases) are heated, they expand and therefore become less dense. Any object or substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water.
Explanation:
When you heat up water, the water molecules start moving around faster and faster. ... So hot water is less dense than cold water. When you put the two together with the hot water on the bottom, the hot water rises to the top.

Which process would change metamorphic rock to igneous rock?
Answer:
If the freshly created metamorphic rock is exposed to enough heat, it may melt and become molten (magma). Igneous rock is formed when molten rock cools. Sedimentary and igneous rocks can both create metamorphic rocks.
The process that would change metamorphic rock to igneous rock is to treat metamorphic rock at extremely high temperatures and pressure that effectively transform it into a molten state. And this molten magma cools and crystallizes completely giving rise to the production of igneous rock.
What is Metamorphic rock?Metamorphic rock may be defined as a type of rock that is significantly obtained due to the series of alterations in the pre-existing rocks. These alterations emerge due to changes in environmental conditions.
According to the context of this question, igneous forms are synthesized when the molten metamorphic rock cools and crystallizes due to the result of volcanic eruptions and melted rock inside the earth's crust. This happens due to the generation of extremely high temperatures and pressure.
Therefore, the process of formation of igneous rock from metamorphic rock is well described above.

Answer:
A close, interdependent relationship between two organisms is called SYMBIOSIS . There are three main types of symbiotic relationships. In MUTUALISM, both organisms benefit from the relationship. When one organism benefits but the other is harmed, their relationship is called PARASITISM. Occasionally, two organisms have a relationship where one organism benefits and the other is neither hurt nor helped. This type of relationship is called COMMENSALISM.
The type of relationship where one organism benefits and the other is neither hurt nor helped is called commensalism.
What is commensalism?In biology, commensalism is a connection between members of two different species in which one species uses the other for food or other purposes without causing the other any damage or gaining anything in return.
The commensal, or species that gains from the connection may take resources from the host species, which is unharmed, or find refuge, support, or means of movement. Frequently, a bigger host and a smaller commensal are in a commensal relationship.
The commensal species may exhibit significant morphological adaptation, whilst the host organism is virtually unaffected by the contact. Contrasting this connection with mutualism, which benefits both species,
A well-known illustration of a commensal is the remora (family Echineidae), a fish that travels in close proximity to sharks and other fish. Remoras have developed a flat, oval-sucking disc structure on top of their heads that cling to the bodies of their victims.
Remoras and pilot fishes both eat the leftover food from their hosts. Bird species like the magnificent egret (Ardea alba), which feeds on insects discovered by grazing animals or on soil creatures stirred up by plows, are other instances of commensals.
Therefore, this type of relationship is called commensalism.

Describe how photosynthesis transforms energy from sunlight to chemical energy?
Answer:
Most life on Earth depends on photosynthesis.The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.
Explanation:
What helps weaken atp bonds so energy can be released and then later help reform them?
Enzymes help weaken these bonds so energy can be released and then later help reform them.
that's the answer
ADP (adenosine diphosphate) is formed when these high-energy connections between the phosphate groups at the end are broken, releasing energy for the cells to utilize.
How is energy stored in ATP?One phosphate group is left on its own, these powerful associations may be broken and rebuilt with the aid of enzymes.
When a third phosphate is added to the ADP molecule, reforming ATP, water that was broken down into its hydrogen atom and hydroxyl group during ATP hydrolysis is recovered.
Energy must be introduced into the system to regenerate ATP, ADP develops and energy is released for the cells to utilize when these connections are broken.
Therefore, ATP has the capacity to store and transmit chemical energy, high-energy bonds are used to link the final two phosphate groups.

In basidiomycete fungi, the nuclei from parents combine in the BASIDIA to make offspring spores. Basidia are microscopic structures but they are generally produced on large fructifications known as fruit bodies.
A basidium is a sporangium localized on the hymenophore of the fruiting bodies in basidiomycete fungi.
In basidia, the nuclei of two parental strains fuse by karyogamy and then divide to reproduce basidiospores.
A basidium generally contains four sexual spores known as basidiospores.
