A construction company has clear-cut all the plants on the land next to a river. It plans to build many large homes on the land. During the construction, there are
periods of heavy rain. Large areas of red mud run off into the water, causing the water to become extremely cloudy. Which effect will these mud particles most
likely have on life in the river?
A) The mud particles will decrease the turbidity of the water, making it less difficult for plants to photosynthesize.
B) The mud particles will decrease the turbidity of the water, making it more difficult for plants to photosynthesize.
C) The mud particles will increase the turbidity of the water, making it less dificult for plants to photosynthesize.
D) The mud particles will increase the turbidity of the water, making it more difficult for plants to photosynthesize.
Answer: C). The mud particles will increase the turbidity of the water, making it more difficult for plants to photosynthesize.
Explanation:
The run off of the red soil and the construction material in the form of mud particles will contaminate the river water. This will increase the turbidity of the water of the river. The turbidity will not allow the penetration of sunlight into the river water as a result the plants will not get sunlight which is necessary for the process of photosynthesis. In the presence of sunlight the green plants prepare their own food by using carbon dioxide and water so as to produce the carbohydrates in the form of food.

1. How does a clock and its internal and intricate mechanical parts make up a system(Explain)
2. Is it a living or nonliving system? (Explain)
3. How may it support a living system? (Explain)
4. Therefore what is an good example of a definition of a system?
Answer:
1. A clock with internal mechanical parts comprises a system because it is a combination of various parts that a heterogeneous in nature and function working together to achieve one end - indicating the time accurately.
Some mechanical clocks comprise of at least 10 parts namely:
Gear train: This component alone is a sub-system that comprises of at least 8 parts. These parts are broadly classified into wheels, pinions, and barrels.Main SpringPalletEscapement Escapement WheelBarrell Barrell WheelBalance Spring etc2. A clock is a non-living system.
Living systems have certain characteristics. Some of them are:
Stimuli: Response to the environmentGrowth and development: The are able to increase in size and dimensionsHomeostasis: this is the capability of self-regulation regardless of external conditions such as temperature and pressure. etc3. A cannot support a living system. It can however help a human being (which is essentially a combination of various systems) to tell the time.
4. a system is a combination of heterogeneous parts that work in unison to form a whole complex entity that can perform one or more functions.

A strategy for fighting bacterial infections uses viruses. Viruses that infect bacteria are called bacteriophages. Phage comes from the Greek word for “eater.” Explain why it is not accurate to call a virus that kills bacteria a “bacteria eater." What happens when a virus attacks a cell?
help!!
Answer:
Viruses are not living organisms, and for that reason a bacteriophage virus does not feed on bacteria, but uses them to replicate, producing lysis of the bacterial cell in the process.
Explanation:
Viruses are structures formed by genetic material —DNA or RNA—covered by a protein envelope called the viral capsid. These structures do not perform the vital functions of a cell, so they are not considered living organisms.
A bacteriophage virus is characterized by using prokaryotic cells to replicate, destroying them in the process.
Viruses need a living cell to be able to replicate, so they introduce their viral genome into them to replace the genetic material of their nucleus and be able to multiply. They can do this:
Introducing the genetic material from outside the cell. Entering directly into the cell to be able to replicate.Bacteriophage viruses do not eat the bacteria, they simply use it to reproduce, and then happens the lysis of the bacterial cell.
Answer:
Viruses are not living organisms, and for that reason a bacteriophage virus does not feed on bacteria, but uses them to replicate, producing lysis of the bacterial cell in the process.
Explanation:
Matter and energy can never bee created or destroyed. Explain how photosynthesis and cellular respiration demonstrate this law of nature.
They're linked. Cellular respiration uses oxygen and glucose from photosynthesis. Photosynthesis uses carbon dioxide, water, and energy from cellular respiration. Energy is transferred to other processes, not created or lost.
What is law of conservation of matter and energy?According to the law of conservation of mass or principle of mass conservation, any system that is closed to all exchanges of matter and energy must have a constant mass over time since the system's mass cannot vary and neither add nor subtract quantity.
Photosynthesis and cellular respiration are connected. Oxygen and glucose are obtained through photosynthesis and used in the process of cellular respiration. Carbon dioxide, water, and the energy released during cellular respiration are the three primary components of photosynthesis. Energy is not created nor destroyed; rather, it is transferred to other processes.

Acid rain is caused by combustion chemicals mixing with water vapor in the atmosphere. It normally results in high amounts of acid in the soil, and surrounding bodies of water.
what is the last thing that happens when a cell divides to produce two new identical cells
Answer:
The last phase of cell division is cytokinesis. In this phase the cytoplasm of parent cell divides in to two cells called as daughter cells. It occurs during late stages of nuclear division.
The visible change of cytokinesis in an animal cell can be observed as formation of Furrow or Pucker on the cell surface.
What would be the expected result if a competitive, nonhydrolyzable analog of ATP were applied to the cytoplasmic side of a plasma membrane that contained a large concentration of the Na+/K+ pump? What would be the expected result if a competitive, nonhydrolyzable analog of ATP were applied to the cytoplasmic side of a plasma membrane that contained a large concentration of the Na+/K+ pump? The cell would accumulate Na+, but there would be no effect on K+. The cell would accumulate K+, but there would be no effect on Na+. The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations. Both Na+ and K+ would accumulate outside of the cell.
Answer:
The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations.
Explanation:
The Na/⁺K⁺ pump is an ATPase pump which is responsible for maintaining low Na⁺ and high K⁺ concentrations within the cytoplasm while maintaining high Na⁺ and low K⁺ concentrations in the extracellular fluid.
Since these two ions are moved against their concentration gradient, ATP hydrolysis is required to provide the energy for this process. This is done by moving in two K⁺ ions inside while moving three Na⁺ ions outside the cell for every molecule of ATP hydrolysed to ADP and Pi.
If a competitive non-hydrolyzable analog of ATP is applied on the cytoplasmic side of a plasma membrane that contained a large concentration of the Na/⁺K⁺ pump, it will act by inhibiting the action of the Na/⁺K⁺ pump. This will result in an accumulation of Na⁺ ions inside the cell and lower than normal K⁺ ions concentration.

A.
Lane 7
B.
Lane 2
C.
Lane 3
D.
Lane 4
its for Environmental Science
Answer:
Lane 4
Explanation:
Based on the information that is provided, it seems that the gel electrophoresis analysis was conducted to determine the presence or absence of carp DNA in water samples from six different sites.
What happens in the process of gel electrophoresis ?In gel electrophoresis, DNA fragments are separated based on their size and charge by applying an electric field to a gel matrix. The negatively charged DNA fragments move towards the positively charged electrode, with smaller fragments moving faster and migrating farther down the gel than larger fragments.
In this particular gel, lane 7 is the negative control, which means that it should not show any bands of DNA fragments. Lane 8 is the positive control, which should show a band of DNA fragments of known size and sequence. The purpose of the positive control is to ensure that the gel electrophoresis is working properly and that the expected band is present.
If the bands formed in lanes 1, 3, 5, and 6 correspond to the band in the positive control lane (lane 8), then it suggests that carp DNA may be present in the samples taken from those four sites.
However, it is important to note that this inference is based on assumptions and limited information provided, and a more thorough analysis and interpretation of the gel electrophoresis results would be required to draw definitive conclusions about the presence or absence of carp DNA in the water samples from those sites.

WHAT IS THE MAJOR EVOLUTIONARY ADVANTAGE TO PRODUCING AN AMNION?
The main evolutionary advantage of producing an amnion is that the embryos of the amniotic membrane,the amniotes are made available with their own aquatic environment,this in-turn resulted to a lesser dependence on water for it's maturation and development therefore allowing or giving room for the amniotes to branch towards environments that are drier.
WHAT FOES THAT MEAN GOR EMBRYONIC DEVELOPMENT OF THE ANIMAL PHYLUM AS COMPARED TO THE ANIMAL PHYLA?
The embryonic development of animal phylum is also known as embryogenesis.
It is the development of the embryo from the point of fertilization of an egg,(the ovum) by a sperm cell ,this makes the fertilized egg a diploid cell otherwise known as a zygote.
This zygote undergoes mitosis,a mitotic division known as cleavage and a differentiation resulting in a multicellular embryo.
This embryonic development of animal phylum comprises of 36 animal phyla.
