Answer:
They once thought that humans came from monkeys and apes but now they think they come from a ancient ancestor not from the monkey or ape family.
Explanation:
A human general manner of life, including what it consumes, how it grows, and where it may dwell, might change throughout time as a result of genetic change.
What is human evolution?New genetic variations in early ancestor populations favored new capabilities for environmental adaptation, which then in turn altered the human way of life and facilitated human development.
It is generally accepted that the development of modern humans from our hominid ancestors involves four main stages in evolution, developing terrestriality, bipedalism, a huge brain (encephalization), and civilization.
They more than likely came from Africa within the last 200,000 years, an ancient form of human called Homo erectus
Therefore, Homo erectus, meaning means "upright man" in Latin, is most likely the most recent common ancestor of today's humans,

Which of the following substances is the most acidic?
a substance that has a pH of 7
a substance that has a pH of 2
a substance that has a pH of 8
a substance that has a pH of 5
pH=-lg[H+]
from the formula of the pH you can deduct that the lower the pH the more hydrogen protons are released. The easier it is for a compound to release protons the more acidic it is. Therefore the correct answer is a substance that has a pH of 2
The substance with the lowest pH would be highly acidic. Therefore, the substance with pH 2 is the most acidic.
A pH scale is useful to express the concentration of hydronium ions on a logarithmic scale. The negative logarithm (with base 10) of the activity of the hydrogen ion (H+) is used to determine the pH of acids and bases.
The substance with pH 7 has a neutral pH according to the pH scale.
A substance with pH 8 is slightly basic, while a substance with pH 5 is slightly acidic.
Therefore, a substance with pH 2 is most acidic is the correct answer.

description of shrubland biome
Answer:
The shrubland is a biome dominated by shrubs, with distinct seasons where one tends to be longer and drier while the other one tends to be shorter and wetter.
Explanation:
The shrubland is a biome that is mostly found as a transitional biome between the tropical and temperate biomes. This biome has a clear distinction between seasons. The summers are very hot and dry, experiencing prolonged drought, while the winters are mild to cool, and it is when most of the precipitation falls. This biome is exclusively terrestrial, thus it can only be found on land.
The landscape is dominated by shrubs. The shrubs tend to have needles and sharp leaves, and they are very well adapted to withstand high temperatures and prolonged drought. The animals too are well adapted to survive in dry conditions. Because this biome is suspectable to wildfires, the vast majorty of the animals use be it because of the manner in which they live or as a shelter.

each plant. Which of the following statements correctly describes the
independent and dependent variables in Helen's experiment?
A: The independent variable is the amount of sunlight, and the dependent variable is the
number of new leaves.
B: The independent variable is the kind of plant, and the dependent variable is the
amount of sunlight
C: The independent variable is the amount of sunlight, and the dependent variable is the

D: The independent variable is the number of new leaves, and the dependent variable is
the amount of sunlight.
Answer:
A) The independent variable is the amount of sunlight, and the dependent variable is the number of new leaves.
Explanation:
hope this helps! good luck!
Helen is studying the growth of two different types of plants. Sunlight is an independent variable as it varies and the number of new leaves is the dependent variable. Thus, Option A is correct.
What are the independent and dependent variables?The Independent variable is the variable that is changed in a scientific experiment. Temperature is an example of an independent variable.
The dependent variable depends on other variables. The amount of leaves that grow on the tree is determined by how much sun the plant is receiving. The amount of sunlight may vary, therefore, it is the independent variable and the number of new leaves is the dependent variable.
The amount of shade that is given is the independent variable. The intensity of sunlight may change day by day. The amount of leaves that grow on each plant is the dependent variable. Therefore, Option A is correct.

Which of the following statements is NOT true of photosynthesis?
Photosynthesis stores the energy from the Sun in molecules of sugar.
Photosynthesis captures and stores energy from the Sun.
Photosynthesis requires carbon dioxide and water.
Photosynthesis captures and uses energy from the Sun for daily activities.
Answer:
A
Explanation:
The statement 'photosynthesis requires carbon dioxide and water' IS NOT true.
Photosynthesis is a series of reactions by which plants and algae can produce sugars (e.g., glucose) by using the energy from the sun, oxygen and water.The photosynthetic reactions release carbon dioxide (CO2) as a byproduct, thereby CO2 is a product instead of a reactant.Photosynthesis has two main types of reactions: light-dependent reactions and light-independent reactions (i.e., the Calvin cycle).In conclusion, the statement 'photosynthesis requires carbon dioxide and water' IS NOT true.

Answer:
species
Explanation:
Organisms that are the most closely related genetically would belong to the same species, which is the most specific taxonomic level.
What are taxonomic levels?Taxonomic levels are a hierarchical system of classification used to categorize and study the diversity of life based on shared characteristics and evolutionary history.
The taxonomic levels, in order from the most specific to the most general, are species, genus, family, order, class, phylum, kingdom, and domain. Each level represents a group of organisms that share a certain set of characteristics and a common ancestry. This system of classification allows scientists to understand the relationships and diversity of life on Earth.
