Photosynthesis stops due to the atmosphere filled with dust after a meteor strike on Earth. Why would the dust cloud stop photosynthesis?
Answers
The rays of sunlight has been obscured by the dust cloud thereby stopping photosynthesis.
Photosynthesis is defined as the process which green plants use in the production of their own food. in the presence of sunlight.
A meteor strike occurs when an extraterrestrial object such as an asteroid or meteoroid passes through the earths atmosphere or hits the earth. this can lead to the atmosphere being filled with dust especially when the incident hits the earth surface.
In the process of photosynthesis, the light stage depends on sunlight to take place.
Because the rays from the sunlight has been hindered by the dust after the meteor strike, the light stage of photosynthesis is inhibited (stopped). Therefore, photosynthesis cannot occur.

Jenny was worried about how some pollutants in a lake near her home were affecting the levels of dissolved oxygen in the water, so
she designed the following experiment.
First, she collected five 10-gallon aquariums and filled each with water from her tap. Then, she tested the initial oxygen level of the
tap water.
Next, she put a tablespoon of different pollutants, including gasoline, cooking oil paint, and lawn fertilizer, in each of four of the
tanks. She stirred those four tanks for 1 minute each to help the pollutant dissolve or spread out in the tank.
Finally, she tested the oxygen level in each tank once every hour and recorded her results in the table below.

Answers
Answer:
Knowing the different stages of the mosquito's life will help you prevent mosquitoes around your home and also help you choose the right pesticides for your needs, if you decide to use them. All mosquito species go through four distinct stages during their life cycle: Egg - hatches when exposed to water.
The two advantage from the study of life cycle of mosquito are:
•It enables us to have better understanding of the ways to reduce and prevent mosquitos bites.
•It helps us to go for the right mosquitos spray that will help in controlling the spread of mosquitos.
Mosquitoes is an insect that be found any where which is why preventing measure needs to put in place so as to avoid or prevent them from biting you skin so as to suck up blood or transmit virus.
Mosquitos are often very energetic especially at sunset to sunrise and they can be found at:
• Home
•Outside Home
•Where their is stagnant water etc
The disease or virus transfer by mosquitos is Malaria, this is cause by Anopheles mosquitoes as it tend to carry the virus in which after biting it victim it transfer the virus into the blood stream of the victim causing what is called Malaria .
Inconclusion The two advantage from the study of life cycle of mosquito are:
•It enables us to have better understanding of the ways to reduce and prevent mosquitos bites.

What is a rectangular prism?
A rectangular prism is a geometrical figure. It is basically a polyhedron and has two congruent and parallel bases. It is also known as a cuboid.
A rectangular prism is made of six faces and each of the faces has twelve edges. It is called a prism because it has cross-sections along the length.
A rectangular prism is a three-dimensional figure with six faces. All the faces of the prism are rectangular in shape. Hence, there are three pairs of identical faces here. A rectangular prism is also called a cuboid due to its shape.
The rectangular prism has 6 faces, 12 edges and 8 vertices.
The top portion and the base portion of the rectangular prism are always a rectangle. It has three dimensions like a cuboid. These are length, width and height. The opposite faces of the prism are always congruent.
Therefore, the parallel lines to BD are PY, MK and AH. So the correct options are A, D and E.

Which step of cellular respiration is shown in the image?
glycolysis
lactic acid fermentation
electron transport chain
Krebs cycle
Answers
Answer:
electron transport chain
Explanation:
just took the quiz
The image shows the C. electron transport chain (ETC) step of cellular respiration
What is the electron transport chain ?The ETC is the final stage of cellular respiration, where oxygen is used to create ATP. NADH and FADH2, which are produced in the Krebs cycle, donate electrons to the ETC.
The electrons are passed through a series of proteins, which release energy that is used to pump protons across the mitochondrial membrane. This creates a proton gradient, which is used to power ATP synthase to produce ATP
The Krebs cycle and lactic acid fermentation are both earlier steps in cellular respiration. In the Krebs cycle, pyruvate is oxidized to produce NADH, FADH2, and ATP. In lactic acid fermentation, pyruvate is converted to lactate, producing NADH.

There are a dozen eggs in a carton. Twelve people each take a single egg, but there
is one egg left in the carton. How?
Answers
Lateral thinking: There are a dozen eggs in a carton. Twelve people each take a single egg, but there is one egg left in the carton. This is only possible if the last person to take the egg, took it along with the carton, leaving the egg in the carton only.
What is lateral thinking?Lateral thinking is that approach of solving problems which is creative and involves out - of - box ideas. The solution might not have anything to do with logical reasoning. The solution might differ for different people i.e., there can be more than one solution.
For example, in this question, when twelve people took twelve eggs, one each, from the carton, there is no mathematical or logical solution to how one egg is left in the carton. But we can reach for a lateral approach that the last person took the carton along with the egg, keeping the egg inside the carton.

Which explains why secondary succession generally occurs more rapidly in an area than does primary succession?
A) Average precipitation is higher
B) Moderate climatic conditions exist
C) Pioneer species are microscopic
D) Soil formation has already occurred
Answers
Answer:
Secondary succession usually occurs faster than primary succession because the substrate is already present. In primary succession, there is no soil and it needs to form. This process takes time, as pioneer species must colonize the area, they must die, and as this happens over and over again, soil forms.
