1. How many cells would you expect to find in a multicellular organism?
Answer:Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells
Explanation:
Answer:
Hmm.
Explanation:
Organisms made up of more than one cell are categorized as multicellular organisms.
Which statement gives an advantage of multicellular organisms?
They can perform more functions.
They can reproduce quickly.
Their size allows them to maintain structure easily.
One cell performs all of the necessary functions.
Answer:
D
Explanation:
Bacteria can reproduce quickly which is why it is sometimes hard to get rid of a cold.
Both types of cells carry out necessary functions to survive.
Size does not define a cell.
Multi-cellular organism have complex cell structure in which each cell has the ability to tend to it's necessary functions.

Which factors involving the activities of people are a threat to biodiversity? pollution and succession habitat loss and predation poaching and habitat loss succession and poaching
Both poaching and habitat loss are a threat to biodiversity
Habitat loss refers to the destruction of natural ecosystems and consequent reduction in the amount of habitat available for the species living in a given area. Habitat loss is the greatest threat to ecosystems biodiversity and conservation worldwide by deteriorating natural areas and thereby reducing species distribution ranges. Habitat loss is primarily due to the expansion of human populations and human activities (i.e., mining, logging, trawling, industrial production, urbanization, etc.).
Poaching refers to the illegal killing of wild animals for different reasons (e.g., meat, recreation, etc.), in violation of international, federal, state/provincial, or local laws. Poaching can drastically reduce the number of organisms in natural populations, thereby this human activity can reduce genetic diversity and eventually may lead to the extinction of natural populations/species.
In conclusion, both habitat loss and poaching can reduce the number of organisms, reduce biodiversity and eventually cause the extinction of natural populations.

Which two organelles work together to create a functional protein.
Answer:
J
Explanation:
The two organelles that work together to create a functional protein are the ribosome and the endoplasmic reticulum (ER).
What if the function of ER and ribosome?The ribosome is responsible for synthesizing the protein, while the endoplasmic reticulum provides the environment in which the protein can fold into its functional 3-dimensional structure.
In the cytoplasm, the ribosome reads the genetic information in messenger RNA (mRNA) and uses it to assemble a chain of amino acids, forming a protein. The ribosome then transfers the newly-formed protein to the endoplasmic reticulum.
The endoplasmic reticulum is a network of membranes that runs throughout the cytoplasm. It is involved in many cellular processes, including the folding and modification of newly-synthesized proteins. In the ER, the protein undergoes a series of post-translational modifications, such as the addition of carbohydrates, lipids, or phosphate groups. These modifications help the protein fold into its functional 3-dimensional structure and determine its final function in the cell.

how new technology and experimental methods can lead to changes in theories.
Answer:
New findings and new evidence about a scientific theory can change the aspects of this scientific theory and in some cases, it can be proved as wrong or can be supported by more strong evidence that can prove its liability.
New technology allows scientists and researchers to study various untouched aspects and leads to find new evidence to support or prove the theory can be either change or unproven.
Thus, new technology and experimental methods can lead to changes in theories.

A. Organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels.
B. Organisms at higher trophic levels require smaller habitats than organisms at lower trophic levels.
c. Organisms at lower trophic levels provide less energy than organisms at higher trophic levels.
D. Organisms at lower trophic levels outcompete organisms at higher trophic levels.
Answer:A
Explanation:
The statement provides the best explanation for the difference in biomass of organisms found at each trophic level is: organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels.
WHAT IS TROPHIC LEVEL:Trophic level of an organism refers to the position of the organism in the flow of energy in an ecosystem. Organisms feed on one another in an ecosystem to obtain energy needed for their metabolic activities. More energy is contained in lower trophic levels than that of higher trophic levels. This means that, according to this question, more energy is in the producers than tertiary consumers.Therefore, the statement provides the best explanation for the difference in biomass of organisms found at each trophic level is: organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels.

Explanation:
why does the density of liquid water increase as it cools?
The density has been inversely proportional to the volume of the substance and the temperature. The density of the liquid water increases as it cools as the temperature decreases.
What is the relation between density, volume, and temperature?The density of the substance has been defined as the place occupied by the substance in a liter or milliliter of solution. It has been known to show an inverse relationship between volume and temperature.
As the liquid water cools down its temperature starts decreasing which causes the collision of the particles and kinetic energy to decrease leading to decrease in the volume of the matter as particles start moving close to each other.
As a result, the volume of the substance gets decreases which inversely affects the density of the material. The decreased volume increases the density of the substance. Hence, density shows an opposite reaction to the factors like temperature and volume.
Therefore, an increase in density is due to a decrease in the volume of the matter.
