Why do living things share fundamental characteristics
Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
Life processes are important to carry out daily life activities. They help to produce energy and maintain homeostasis in the body. The life processes help a body survive with the changes in the environment.
There are several fundamental characteristics or capacities that all living things share, including order, environmental sensitivity or responsiveness, reproduction, growth and development, regulation, homeostasis, and energy processing.
What fundamental characteristics share by living things?All living things share certain basic characteristics or functions, such as order, sensitivity to their environment, growth and development, reproduction, regulation, homeostasis, and the ability to process energy.
These characteristics work to define what it means to live. These characteristics collectively contribute to the definition of life. All of these characteristics will be found in living things.
All living things share the capacities to procreate, grow and develop, use energy, maintain homeostasis, respond to their environment, and be adaptable.
Therefore, all living things share fundamental characteristics.

Enzymes are biological catalysts. Enzymes are proteins that are found inside cells to
increase the rate of chemical reactions within each cell. Enzymes are denatured
(destroyed) by various environmental conditions. Amylase is an enzyme in the digestive
system that helps to break down complex carbohydrates into simple sugars.
HYPOTHESIS: Amylase works best in an environment with a pH level of 7. what is the independent and dependent variable sum1 please help!
Answer:
Explanation:
independent= pH as you will change the pH in order to test your hypothesis and see if it's true
dependent= how amylase works-needs to be measured so you can see how easily it does it function depending on the pH (dependent on the independent variable)
The independent variable is pH, you change it to test your hypothesis; The dependent variable is the activity of amylase enzyme depend on the pH value.
What are the properties of an enzyme ?Enzymes are protein catalysts that speed up the rate of biochemical reactions
The enzyme activity is pH-specific, catalyze both forward and reverse reaction but do not decide the direction of the biochemical pathway.
An enzyme have active site which bind to substrate and form desired products.
Several factors influence the enzyme activity like heat, temperature and varying pH.
Enzyme show absolute, relative, group, stereo-specificities and regulatory function.

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.

The elements potassium (K) and chlorine (CI) can form an ionic bond. Which of the following
statements correctly explains what occurs (in this ionic bonding)?
1.) As chlorine has 7 valence electrons, it tends to form bonds to gain one electron (to get a full valence shell of 8).On the other hand, potassium has one valence electron, so it tends to lose this electron to other atoms (and
become a cation)
2.) As chlorine has 7 valence electrons, it tends to form bonds to lose all 7 electrons. On the other hand,potassium has one valence electron, so it tends to gain 7 electrons (to get a full valence shell of 8).
3.) In this ionic bonding, potassium is the anion and chlorine is the cation.

Thank Youwhy 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.

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.
