Longitudinal waves are waves that transfer energy parallel to the direction of wave motion. Transverse waves are waves that transfer energy perpendicular to the direction of wave motion.

Answers

Answer:

Longitudinal waves are waves that transfer energy parallel to the direction of wave motion.

Transverse waves are waves that transfer energy perpendicular to the direction of wave motion.

Explanation:

First of all, transverse waves are not mechanical waves at all. Longitudinal waves are mechanical waves.

Longitudinal waves are waves that transfer energy parallel to the direction of wave motion. A typical example of longitudinal waves is wave on a spiral spring.

Transverse waves are waves that transfer energy perpendicular to the direction of wave motion. A typical example of a transverse wave is light wave and other electromagnetic waves.

A cell is placed into a solution and is left sitting for 24 hours. When you come back you notice the cell is exactly the same size it was beforehand. Which type of solution was the cell sitting in? Explain

Answers

Answer:

Isotonic Solution

Explanation:

There are commonly three types of solutions:

Hypertonic solution = the concentration of solute is greater than in the cellHypotonic solution = the concentration of solute is less than in the cellIsotonic solution= the concentration of solution and cell is same.

So, if the cell was in any other solution, it would have been burst or it would shrink. but nothing changed because it was in a solution where outside environment is similar to the internal environment

Apply Concepts Eventually, most people with Alzheimer's disease lose the ability to recognize common objects. Explain which lobe is affected at this point in the disease

Answers

Answer:

The right temporal lobe

Explanation:

The cerebral cortex of the brain has two sections known as hemispheres, and each hemisphere can be divided into four lobes: frontal, parietal, temporal and occipital. Alzheimer's disease is the most common cause of dementia, which is characterized by the damage of the temporal lobe. Alzheimer’s disease usually initiates in the hippocampus, which is a structure inside each temporal lobe. The temporal lobes are involved in different neuronal functions: object recognition, face recognition, perception, memory, language, emotions, etc. The right temporal lobe is mainly involved in processing visual information (i.e., face recognition, object recognition, familiar recognition).

Which of the following statements is correct?
A. Landfills solved pollution problems caused by waste disposal.
B. Wastewater from cities no longer carries toxic chemicals into waterways.
C. Laws regulating waste disposal have put an end to pollution problems caused by waste.
D. Much of the pollution in our environment is a byproduct of inadequate waste disposal.

Answers

Answer:

D

Explanation:

all the others are false

Much of the pollution in our environment is a byproduct of inadequate waste disposal, hence option D is correct.  

What are the problems of waste disposal?

There are some problems caused by solid waste disposal include: finding suitable landfill locations, groundwater pollution, and soil pollution.

Landfills have not solved pollution problems caused by waste disposal, because it creates soil pollution in the area where waste is disposed of, which decreases the fertility of the soil.

Wastewater from cities carries toxic chemicals into waterways, which is the major cause of water pollution in that area. There are some laws that regulate pollution, but not all the person follows them.

Therefore, waste disposal is the major factor of pollution.

The term that describes the allele that determines the phenotype of an individual organism when two different copies are present in the genotype is?
A. Recessive
B. Nucleus
C. Dominant
D. Eukaryotic

Answers

Answer:

A. Recessive

Explanation:

Only answers A and C can be used to describe an allele, so B and D can't be it. If the allele was dominant, only one copy would be necessary for the phenotype to be expressed (ex. heterzygous green peas are still green, even though they carry a yellow allele). Therefore, since 2 copies are present for this phenotype, it must be recessive.

what are the energy-storing compounds in photosynthesis?

Answers

Answer:

Hi, Plants store their energy in the form of starch, which is a complex carbohydrate that can be broken down into a simple carbohydrate (glucose) for the plant to use for energy. Plant cells store starch in storage organelles as all cells do. (vacuoles).

Answer:

Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth.

Answers
