Answer:
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition
Answer:
Explanation:
Run off from agricultural wastes which contain Nitrogen and Phosphorus are the major sources causes dead zones.The process where these chemical get washed into the aquatic bodies is called Eutrophication.
These substances leads to algae boosts in the water.The increases population of the algae consumes the available oxygen in the water, therefore making the oxygen concentration drops or no oxygen at all;(Hypoxia)
As the algae population feed on the available resources in the water they exhausted this,and later die.
When the decomposing bacteria used the oxygen in the water to breakdown the dead algae they make use of the available oxygen.This further reduced the oxygen availability and therefore reduces the oxygen and hence the zone becomes the dead zone, because little or no oxygen is available for survival of organisms.
This is reversible if the process if europhication or other causes is eliminated

Explanation:
saturn and Uranus are alike in that they
Answer:
The correct answer is they both have rings around them
Explanation:
Saturn and Uranus are both planets in our solar system; indeed Saturn is the sixth planet while Uranus is the seventh planet. Besides this, Saturn and Uranus are giant planets, this means they are composed of gas or similar materials and they are massive. Moreover, as giant planets these two planets have a ring system, which means around them, there are dust and other particles that orbit the planet and form rings; although, in the case of Saturn these are massive and more visible. According to this, Saturn and Uranus are alike because they both have rings around them.
Answer:
They both have rings around them.
Explanation:
The only 4 planets in our solar system that are gas giants have rings.

General intelligence, commonly referred to as the “g factor,” is a wide mental capacity that affects how well on cognitive ability tests a person does. Thus, option B is correct.
What is general intelligence?It is possible to describe general intelligence as a construct made up of various cognitive skills. These skills enable people to learn new things and resolve issues.
Underlying specialized mental talents in domains like verbal, spatial, numerical, mechanical, and mechanical abilities is this general mental capacity.
It is hypothesized that general intelligence influences how well people perform on all cognitive tasks.
You can relate general intellect to athletic ability. A person may be an exceptional runner, but this does not automatically make them a great figure skater.
Therefore, Dr. Ron supports the notion of general intelligence.

During cellular respiration, the chemical energy from food is transferred into which of the following molecules that can be used as an energy source by enzyme throughout the cell?
A
Ribonucleic acid (RNA)
B
Adenosine triphosphate (ATP)
C
Deoxyribonucleic acid (DNA
D
Triglycerides
Answer:
The first stage of cellular respiration, called glycolysis, takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP. The organelle called a mitochondrion is the site of the other two stages of cellular respiration
What are the roles of different organelles in a cell?
Answer:
Functions of different cell organelles:
Nucleus: contains all the genetic material, acts as information center and tells all the organelles what to do, RNA transcription.
Mitochondria: generates energy through respiration
Endoplasmic recticulum (rough): transport and storage of material; (smooth ER): creation of lipids and fats
Ribosome: protein creation by RNA translation
Golgi apparatus: responsible for synthesis, packing and processing of proteins
Chloroplast: responsible for glucose creation (by photosynthesis)
Cytoplasm: is region where all chemical reactions take place and is the jelly like fluid that holds all the organelles in place inside of the cell
lysosome: responsible for breakdown of larger molecules
Flagellum (or flagella): tail like organelle, assists motion
Vacuole: helps in maintenance of homeostasis and stores waste products or other materials like water / food
cell membrane: separates cell from the rest of the environment and controls what comes in and out of the cell
cytoskeleton: supports cell structure

Water is essential for life. Its special properties make water the single most important molecule in plant life. Which of the following properties of water enables it to move from the roots to the leaves of plants?
Answer:
Because water exhibits cohesive behavior.
Explanation:
Cohesive behavior can be explained as a behavior where molecules are attracted to each other.
And this means that, water molecules are attracted to each other because of their cohesive behavior. This makes them to be attracted to other substances, such as the walls of the xylem of plants.
In this case, it is believed that the water molecules behave this way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.

Compare transitional aquatic ecosystems. Identify two types in the organizer below and describe the environments each type combines. 9th grade Biology
Answer:
The correct answer is -
wetlands - land and water
estuaries - freshwater and salt water
Explanation:
There are three types of aquatic ecosystems that are lentic, lotic, and wetlands. Lentic ecosystems include slow-moving or non-moving water systems like pools, lakes, or ponds. The Lotic system on the other hand is aquatic systems with faster-moving water systems like the ocean or river also known as estuaries.
Wetlands are the system that has unique properties of having vegetation adapted according to the condition or situations on the water in saturated soil flood with water seasonally or permanent.
Aquatic system organizers
wetlands - land and water
estuaries - freshwater and salt water
The zika virus was first identified in Uganda in 1947. The virus is transmitted from person to person by a bite from a mosquito. It is commonly carried by the Aedes mosquito which is prevalent throughout Central Africa. The virus has more recently spread to the Americas (South, Central, and now North) and is expected to spread to Europe. There is a concern that the virus may reach epidemic proportions. Zika virus is related to yellow and dengue fever. Common symptoms are low grade fever and a distinctive skin rash and other symptoms include vomiting, headache, and muscle and/or joint pain. Pregnant women should avoid traveling to areas known to have zika virus present because the virus is known to cause microcephaly and developmental difficulties related to the central nervous system. Based on the paragraph above, class discussions, and other VALID (be careful with your selection of e-materials! CDC – Center for Disease Control is a good place to start) sources of information please answer the following questions. State a reason why the virus has spread to the Americas and likely to spread to Europe. Define the term microcephaly. What bones of the fetal skull would be affected by zika? Specifically, what area of the CNS is not fully developed in microcephalic individuals. In 1 -3 sentences describe the developmental difficulties of microcephalic individuals. How does one know if they have contracted zika? Do men need to be concerned about contracting zika? How does one avoid contracting zika? In a short paragraph (2-5 sentences!) provide one example of a scientific measure that could possibly control the spread of zika and explain how the measure works (controls the spread).
Answer:
1.Most people infected with the Zika virus have no signs and symptoms, while others report mild fever, rash and muscle pain. Other signs and symptoms may include headache, red eyes (conjunctivitis) and a general feeling of discomfort. Zika virus is also called Zika or Zika virus disease. 2.The frontal and parietal bones, but not the occipital bone, collapse over the injured brain. Almost all of the children had prominent calcifications in the brain. Unlike in children infected with cytomegalovirus, periventricular calcifications are the exception in children infected with Zika virus. 3.No they should not be worried.
