A. -experiencing sunrise and sunset.
B. -closest to and farthest from the Sun.
C. -halfway between the Sun and the Moon.
D. -closest to and farthest from the Moon.
Answers
High tide is occurring on the sides of the Earth that are closest to and farthest from the Moon. The correct option is D.
What is high tide?When the sea or a river reaches its greatest level and moves the farthest up the beach or the bank, it is said to be at high tide.
The gravitational forces that try to pull the water away from the moon are resisted by the water that is travelling away from the moon.
On the far side of the Earth, where the moon's gravitational pull is weaker, inertia triumphs, the ocean swells, and high tide happens.
The rise and fall of the sea's surface on a regular basis is what tides, which start in the oceans, appear as as they move toward the coastlines.
High tide is when the wave's highest portion, or crest, reaches a specific area; low tide is when the wave's lowest portion, or trough, happens.
Thus, the correct option is D.

How does ground water relate to lakes or rivers?
All lakes and rivers are replenished by groundwater.
When ground water reaches the surface it can form lakes or rivers.
Groundwater can affect the size of lakes and rivers.
Lakes and rivers produce groundwater.
Answers
Answer:
When ground water reaches the surface it can form lakes or rivers.
Explanation:
Groundwater in valleys is often pushed under pressure by rainwater that falls on the nearby highlands. If the water table reaches the surface, a lake, a river, or a spring is formed. A spring in desert country is surrounded by plants that take advantage of the water supply, forming an oasis. Water now coming to the surface at oases in the Sahara Desert came from rain that fell on hills near the desert during the Middle Ages--eight hundred to one thousand years ago.

Answer:
It allowed us to put a formation date on some geologic crossections
Explanation:
Absolute dating is a newer way of evaluating the chronology of historical events by assigning numerical ages to them. The age thus assigned might not be the exact age but it is still closer to the real age.
It is unlike relative dating techniques which simply give the chronology or order of past events instead of the exact dates. Relative dating techniques have been in use before the emergence of absolute dating techniques in the twentieth century.

The nucleus is like the principal of a school, the cell membrane is like a school building, and the mitochondria is like the staff in a school.
Explanation:
Definitions:
The nucleus of a cell contains the majority of the cell's genetic material, and coordinates cell activities like protein synthesis and cell division.The cell membrane is the semipermeable membrane of a cell that surrounds the cytoplasm (the material inside the cell other than the nucleus).The mitochondria is "the powerhouse of the cell", because it produces most of the chemical energy needed to power the cell's chemical reactions.The nucleus is like the principal of a school: the nucleus controls the cell, much like how the principal controls the school.
The cell membrane is like a school building: the cell membrane forms a boundary between the cell and outside environment, much like how the school building separates you from outside.
The mitochondria is like the staff in a school: the mitochondria powers the cell, much like how the staff in a school keep the school running.

Explanation:
The overload of the emission of carbon in the atmosphere surprised me. The data was recorded and investigated for 2000 to 2100. Different parameters like ocean water and fossil fuel. The fossil fuel when burn contribute to the release of carbon monoxide and carbon dioxide gas. The oceanic water release the decomposed carbon dioxide by calcium carbonate of coral reefs and respiration of aquatic animals.

C.We noticed earlier that the problem of recognizing palindromes is solvable in linear time, which is certainly polynomial time. It is easy to see that PALINDROME is in P. To decide if x is a palindrome, just reverse x and check whether the reveal of x is equal to x.
D.P is an important plant macronutrient, making up about 0.2% of a plant's dry weight. It is a component of key molecules such as nucleic acids, phospholipids, and ATP, and, consequently, plants cannot grow without a reliable supply of this nutrient.
E.Plant cells are differentiated from the cells of other organisms by their cell walls, chloroplasts, and central vacuole. Chloroplasts are organelles that are crucial for plant cell function. These are the structures that carry out photosynthesis, using the energy from the sun to produce glucose.

What arguments would you use to persuade the alien visitor that cars are not alive?
Answers
Answer:
Organisms need 6 things to be considered living which are, responsiveness to the environment, the ability to reproduce, having a metabolism, being able to breathe, maintaining homeostasis, being able to pass down traits, and made of cells. Cars, do not have the ability to reproduce, do not maintain homeostasis, cannot pass down traits, do not have a metabolism, etc... a living being needs to fit all of the criteria to be considered living. In this case, cars do not fit the criteria.
Knowing this, you would tell the alien about the 6 things needed to be considered a living being. After that, you would tell the criteria that the car does not fit which would then explain how a car is in fact, not a living being.

The light-dependent reaction
The light-dependent reaction, as its name implies, occurs inside the thylakoid membrane and necessitates a constant supply of sunshine. The light waves' energy is captured by the chlorophyll and transformed into chemical energy in the form of the molecules ATP and NADPH.
What is Photosynthesis ?
Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities. Despite the fact that various species undertake photosynthesis in different ways, the process always starts when proteins called reaction centres that contain green chlorophyll absorb energy from light. Unlike bacteria, which have these proteins incorporated in the plasma membrane, plants store these proteins in organelles called chloroplasts, which are most prevalent in leaf cells.
When the cell needs energy, ATP can be taken out and used to fuel processes or stored for use in later ones. Animals use ATP to retain the energy released during meal digestion. Similar to this, plants use ATP molecules to store the energy they obtain from light during photosynthesis.
In addition to converting ADP to ATP, photosynthetic processes are used by plants to absorb, process, and store solar energy. Animals convert ADP to ATP, which can subsequently be utilised to drive essential development and cell maintenance, using the energy supplied from the breakdown of glucose and other molecules.
Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidised, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result.

If cells from one part of an embryo are transplanted to another part, and they develop into the tissue they would have made originally, the cells are said to be ____________ .
Answers
Answer:
determined
Explanation:
Determined cells are embryonic cells that will generate all the cell types of the adult organism, with this process being independent of environmental inputs. Cell determination is defined by specific gene expression patterns in embryonic cells. In consequence, cell determination is defined as a genetic process where a particular cell fate can be broken down into two different states: specified (committed) or determined. If a cell is in a committed/specified state, the cell's fate can still be reversed or transformed, while if a cell in a determined state, the cell's fate cannot be reversed or transformed.
