The statement that best describes symbiotic relationships is different species live in close associations in an ecosystem. The correct option is A.
What is the symbiotic relationship?Symbiotic relationships are those relationships in which two organisms live together and depend on each other for nutrition and space. In symbiosis, both organisms help each other.
For example, cattle and egret. The egret is a wading bird that feeds on the ticks or lice of the cattle. Eating them through the body helps clean the body of the cattle, and it also provides nutrition to the egret.
In an ecosystem, different organism lives together. Tress provides space and food for the animals. Animals help in the dispersion of seeds of various plants. In short, it is symbiosis.
Thus, the correct option is A. Different species live in close associations in an ecosystem.

The first phase is interphase, during which the nucleus divides and the DNA replicates. The second phase is mitosis, during which the cytoplasm divides. The third phase is cytokinesis, during which the cell divides into two daughter cells.
What is cell cycle ?The cell cycle is the series of events that take place in a cell leading to its division and duplication. It consists of two major phases: interphase and the mitotic phase. The mitotic phase is further divided into two stages: mitosis and cytokinesis.
During interphase, the DNA of the cell is replicated in preparation for cell division. This phase is divided into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).
During G1, the cell grows and prepares for DNA synthesis. During the S phase, the DNA is replicated, resulting in two identical sets of chromosomes. Finally, during G2, the cell prepares for mitosis.
After interphase, the cell enters the mitotic phase. During mitosis, the replicated chromosomes condense and line up at the center of the cell. The nucleus then divides into two identical nuclei, each with a complete set of chromosomes.
After mitosis, cytokinesis occurs, which is the process by which the cytoplasm divides, separating the two daughter cells. The cytoplasmic division usually occurs simultaneously with the telophase stage of mitosis, resulting in the formation of two genetically identical daughter cells.
Therefore, interphase is the phase in which DNA replicates, mitosis is the phase in which the nucleus divides, and cytokinesis is the phase in which the cytoplasm divides to form two genetically identical daughter cells.

The diagram represents the Moon and its orbit around Earth. The arrow labeled X represents the force that keeps the Moon in its orbit. Which force is represented by X?
Answer:
A. Gravity
Explanation:
The strong gravity, or "Pull" of the Earth is what keeps the moon in orbit.
I hope this helps!
Gravity is the force represented by X that keeps the Moon in its orbit. Therefore, option (A) is correct.
What is gravity?Gravity is a force that attracts two objects with mass towards each other. It is the force that gives weight to physical objects and is responsible for the friction between objects and the surface of the Earth.
The strength of the gravitational force between two objects depends on their mass and the distance between them. The greater the mass of the objects, the stronger the gravitational force between them. The farther apart the objects are, the weaker the gravitational force between them.
The most familiar example of gravity is the force that attracts objects towards the surface of the Earth. The Earth has a large mass, so it has a strong gravitational pull. This is why objects on the surface of the Earth are "weighted" and feel heavy.

For her science fair project, your little sister replicated one of Mendel's experiments. From a P0 pea plant with purple flowers and a pea plant with white flowers, she got 1 purple F1 hybrid (she had forgotten to water, so just one survived). From this self-fertilized F1 she got 8 F2 offspring. 7 were purple and 1 was white, for a 7:1 ratio. Did your little sister just disprove Mendel's laws
Answer: No, the 7:1 ratio is close to the expected 6:2 ratio even with the limited sample size.
Explanation:
Let the alleles be P (purple) and W (white).
The possible crosses are
PP x WW, PP x PW, PW x WW, PW x PW
the F1 is PP or PW
one F2 is white so the F1 must be PW and
the F2 are PP, WW, PW and
the expected 8 progeny are 2PP, 2WW, 4PW
Because 7/8 are purple, we can infer that P is dominant and W recessive, so the expectation is 6 purple, 2 white
The observed ratio is similar to the expected ratio, so we can’t say that this result disproves Mendel, particularly with a small sample.
7:1 is close to 6:2, even if the sample is smaller. We cannot invalidate Mendel with such a small sample size because the observed ratio was not statistically different from the anticipated ratio.
What is Mendelian Ratio?The term "Mendelian inheritance" refers to specific patterns that can be observed in the way characteristics are passed down from parents to children. In the 19th century, the Austrian monk Gregor Mendel conducted thousands of tests with pea plants in order to develop these broad patterns. He did this in order to determine the genetic makeup of pea plants.
The frequency with which diverse phenotypes are produced as a result of any cross incorporating Mendelian traits. in particular, the three to one ratio that is displayed by the second generation of descendants from parents who are different from one another in regard to a single character.

List and define the four main elements of the water cycle.
(SCIENCE)
Answer:
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection
Explanation:
Evaporation- Is the the process in which water changes from a liquid to a gas or vapor.
Condensation- Is the process in which water vapor or gas in the air is changed into a liquid. Is the opposite of evaporation.
Precipitation- Precipitation is water from clouds in the form of rain, freezing rain, sleet, snow, or hail.
Collection- This is when water that falls from the clouds as rain, snow, hail or sleet, collects in the oceans, rivers, lakes, streams. Also some will soak into the ground and will collect as ground water.

Why are invasive species dangerous to the environment?
A)They pollute the environment.
B)They are always predators.
C)They threaten biodiversity.
D)They bring abiotic factors.
Answer:
C
Explanation:
They threaten the other animals. They can take their food, homes, and they don't have natural predators.
Invasive species are dangerous to the environment as they threaten the biodiversity. Thus, the correct option is C.
Invasive species are those imported species that are able to thrive rapidly in another foreign area by adapting and reproducing quickly.
Invasive species of plants and animals lead to an increase in the competition for survival, which results in decrease in the population of the native species.
The invasive species also affect the food web that is existing in the particular ecosystem, because of which other all organisms which are part of the food web are affected. They outcompete the native species for food,
Thus, biodiversity is threatened due to the invasive species.
