which of the following is not an example of a trait a)eye color b)ear shape c) species d) body height
Answers
Body height is mainly inherited/ influenced.
Species cannot be changed? So my guess is that C. Is the correct answer as it is not a inherited trait.
If that is wrong, then the answer is D. Because I would think body height is influenced by the two parents.
As per observation the b)ear shape as it doesnt justify genetics laws of inheritence , and law of dominance.
What are traits?It is genetics informtion transfer from parents to offsprings.
The following is not an example of a trait ear shape as it cannot be dominant, and cannot be justified probably instead ear lobes can be there used as a traits.

If you have a storm that has winds of 100 MPH and it is moving at 50 MPH what is the total wind speed with the additive effects?
Answers
Answer:
I would assume 150 MPH, I could be wrong however.
Explanation:
Based on the definition of additive affects, "An effect in which two substances or actions used in combination produce a total effect the same as the sum of the individual effects," I would assume that since the wind speed is 100 MPH and the storm is moving at 50 MPH the total wind speed would be 150 MPH. This would make sense because if you think about it, if a storm with 100 mph winds is coming at you at 50 mph, the force of the 50mph winds would hit you when it gets to you along with the 100 mph winds, but again, I am not totally sure.
Where does the salt in oceans come from?

spy
VI
Answers
Answer:
Minerals from the land are washed into the ocean.
Salt in the ocean comes from the runoffs from the land, So the correct option is C. The minerals from the land are washed into the ocean.
Why are oceans salty?A large percentage of the earth is covered by water but 97 % of this water is salty and cannot be used. The salt in the ocean is added to by the erosion of rocks.
Rainwater contains dissolved carbon dioxide (CO2) from the surrounding air, which makes the rainwater slightly acidic due to the presence of carbonic acid. Rainwater physically damages the rock, and the acids chemically degrade the rock and transport salt and minerals in the form of ions. These ions are carried to streams and rivers, and eventually to the ocean.
The density of the ocean water is affected by the level of salinity. Higher levels of salinity cause water to be more dense and heavier and sink under less salty, warm water. This also affects ocean currents. In addition, marine life may need to adjust their saltwater intake.

What is direct observation?Direct observation refers to the process of observing and recording the behavior or actions of an individual or group without any manipulation or interference. This method is typically used in research studies, such as in psychology, sociology, and anthropology, to study natural behavior and gather data in a non-invasive way.
Direct observation can take place in a variety of settings, including in natural environments, in laboratory settings, or in the field. The observer may use a variety of techniques, such as taking notes, recording audio or video, or using structured observation forms to document the behavior or actions being observed. It is considered a reliable method of data collection as it provides an accurate representation of the actual behavior or actions, rather than relying on self-reported information.

C.

D.

Answers
Answer: D
Explanation:
I believe its D because people with PTSD take pills which are considered as a type of drug pills to get over their anxiety and can calm their nerves. They aren't addicted to this type of pill, they just take it because they need it, not cuz they want it.
The following is not a possible sign of a drug addiction D. using drugs to cope with personal problems. Thus, option "D" is correct.
What are the different stages of drugs?The first stage of drug use is the stage in which the individual starts and continues to use the substance for various reasons. In the tolerance stage, the brain has made significant changes in response to the substance and can no longer produce the same mental or physical effects. The next stages of dependence and addiction are characterized with cravings for the substance, inability to maintain daily responsibilities, spending extra time seeking out the substance and using.
Thus, option "D" is correct.

Steel is an example of a mixture. It's known as an alloy of iron mixed with carbon. The carbon helps to improve its strength and its resistance to fracture. Other percentages of chromium, nickel, vanadium, etc can be added in order to obtain steels of a desired hardness, resistance to corrosion, etc. Due to its high tensile strength, it is used in tools, ships, cars, electrical appliances, weapons, etc.

Which process breaks down sugars to make ATP when oxygen is present?
A Anerobic Respiration
B Cellular Respiration
C Glycolosis
D Photosynthesis
Answers
Answer:
Cellular Respiration
Explanation:
Cellular respiration converts glucose to ATP, glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the phases of cellular respiration, hence option B is correct.
What is cellular respiration?
A glucose molecule with six carbon atoms is split into two pyruvate molecules, each with three, during the glycolytic process.
Glycolysis kicks off the process, a six-carbon glucose molecule is divided into two molecules with three carbons in this initial phase. The molecule with three carbons is known as pyruvate.
Anaerobic (without oxygen) and aerobic (with oxygen) cellular respiration are both possible (without oxygen).
Therefore, during aerobic cellular respiration, glucose, and oxygen combine to create ATP, which the cell may utilize, as byproducts, carbon dioxide, and water are produced, hence option B is correct.

Fermentation is a chemical process by which molecules such as glucose are broken down anaerobically. Therefore, option (A) is correct.
What do you mean by fermentation?Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
Moreover, fermentation occurs in the absence of oxygen (anaerobic conditions), and in the presence of beneficial microorganisms (yeasts, molds, and bacteria) that obtain their energy through fermentation.
Hence, fermentation reactions occur in the cytoplasm of both prokaryotic and eukaryotic cells. In the absence of oxygen, pyruvate does not enter the mitochondria in eukaryotic cells.
