. The small fish are not affected by the pesticide, but death occurs in the bird, at the top of the food chain. Why do you think that happens?
describe the water cycle process starting from an afternoon thunderstorm.
Answer:
Most thunderstorms form by a cycle that has three stages: the cumulus stage, mature stage, and dissipating stage.
Cumulus Stage
The sun heats the Earth's surface during the day. The heat on the surface and warms the air around it. Since warm air is lighter than cool air, it starts to rise (known as an updraft). If the air is moist, then the warm air condenses into a cumulus cloud. The cloud will continue to grow as long as warm air below it continues to rise.
Mature Stage
When the cumulus cloud becomes very large, the water in it becomes large and heavy. Raindrops start to fall through the cloud when the rising air can no longer hold them up. Meanwhile, cool dry air starts to enter the cloud. Because cool air is heavier than warm air, it starts to descend in the cloud (known as a downdraft). The downdraft pulls the heavy water downward, making rain.
This cloud has become a cumulonimbus cloud because it has an updraft, a downdraft, and rain. Thunder and lightning start to occur, as well as heavy rain. The cumulonimbus is now a thunderstorm cell.
Dissipating Stage
After about 30 minutes, the thunderstorm begins to dissipate. This occurs when the downdrafts in the cloud begins to dominate over the updraft. Since warm moist air can no longer rise, cloud droplets can no longer form. The storm dies out with light rain as the cloud disappears from bottom to top.
The whole process takes about one hour for an ordinary thunderstorm. Supercell thunderstorms are much larger, more powerful, and last for several hours.

Compare and contrast the elevated temperature of someone who is exercising vigorously and someone who has an infection
Answer:
Due to muscle contraction and fighting of white blood cells.
Explanation:
Exercise increases the temperature of body because about 20% of the energy produced in contracting muscles is used for muscle contraction while the remaining 80% is converted into heat energy, as a result body's temperature increases whereas a person who has infection also experience high body temperature because the body work faster to fight against the infection that leads to high temperature.

Some people have one sickle cell gene and one normal gene. They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the human system of reproduction result in people getting one copy of a sickle cell gene and one copy of a normal gene? Describe the process.
Answer:
Through meiosis
Please find the description below
Explanation:
Humans reproduce via a type of reproduction called SEXUAL REPRODUCTION. Sexual reproduction is the type of reproduction that involves two sexes (male and female) of an organism. The males produces male gametes called SPERM while females produce female gametes called EGG.
The process by which these gametes is produced is called MEIOSIS. Meiosis is a division that reduces the chromosome number of the parent cells. According to Gregor Mendel, it occurs in such a way only one allele of a gene is present in each gamete.
Hence, according to this question, getting one copy of a sickle cell gene and one copy of a normal gene is as a result of meiotic division of male and female. One parent undergoes meiosis and contributes the normal allele (S) while the other parent undergoes meiosis and contribute the sickle allele (s).

Iron rich deposits that formed about 2 billion years ago have red layers. Layers formed before then were not red. The red layers formed when oxygen made during photosynthesis reacted with iron molecules in the ocean. The oxidized iron formed layers of sedimentary rock
. Which BEST summarizes this phenomenon?
A. The lithosphere changed the atmosphere. B. The hydrosphere change the atmosphere.
C. The atmosphere change the biosphere.
D. The biosphere change the lithosphere
Answer:
D. The biosphere change the lithosphere
Explanation:
The red formed due to oxygen which is produced by plants in the process of photosynthesis. This oxygen then reacted with iron atom and formed oxidized iron layers of sedimentary rock. So here plants are responsible for the formation of these layers and we considered plants as part of biosphere so we can say that biosphere is responsible for the change of lithosphere.

B. Gases dont have a fixed shape:solids do
C. Gases have particles that are closer together than thoes in a solid
D. Gases partical have less energy than solid paeticals.
Answer:
B: Gases dont have fixed shape, solids do
Explanation:
A is false because gases and solids can be both made up of atoms and also molecules
B is true because gases do not have definite shape or volume, while solids have definite shape and volume
C is false because particles of a gas are farther apart under similar pressure, volume and temperature as particles of a solid
D is false because gases have more energy than solid particles under similar pressure, volume and temperature due to their movement they are constantly transfering energy from one particle to another as they move
Answer:
Explanation:A: the atoms in a gas move at high speeds
C: the atoms in a gas spread in all directions

The __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ carries low oxygen blood to the lungs and brings high oxygen blood back to the heart.
Answer:
Pulmonary blood vessel
Explanation:
The pulmonary blood vessel carries low oxygen blood to the lungs and brings high oxygen blood back to the heart.
More specifically, the pulmonary artery carries low-oxygen blood to the lung from the right ventricle of the heart. The blood becomes oxygenated in the lung and the oxygen-rich blood is taken back to the left atrium of the heart by the pulmonary vein.

Explanation:
Aerobic Process: Oxygen, Carbon Dioxide by-product
Anaerobic Process: Carbon Dioxide, Fermentation
Both: Produces ATP, Takes place in cells
What is respiration ?Respiration is a metabolic process in which an organism's living cells use oxygen to obtain energy (in the form of ATP) and release carbon dioxide as a byproduct of the oxidation of complex organic substances.
Anaerobic respiration occurs when there is no oxygen present, whereas aerobic respiration occurs when there is oxygen. Alcohol is produced by anaerobic respiration, whereas carbon dioxide and water are the byproducts of aerobic respiration. Compared to anaerobic respiration, aerobic respiration produces more energy.
Thus, respiration is a vital process of the body.

You are comparing the density of sea water to the density of fresh water. (Remember,
density is mass divided by volume.) Describe how you could determine the density of
sea water, including the names of the equipment needed to make the required
measurements.
Answer:
To know and compare the difference between the density of the fresh water and salt water or sea water require a graduated cylinder, balance, and weighing machine. The graduated cylinders are the containers that have markings on them to measure the volume of the liquid.
First, fill the cylinder with 1000 ml of fresh water which is the measure of the volume. now weight the cylinder filled with the fresh water and then find the difference between filled and empty container divide the mass of the fresh water by its volume, the result is the density of fresh water.
Repeat the process with salt water or sea water. The answer would be sea water has more density than fresh water.

this blood vessel?
lumen
magnification X8
3.1 x 10-2m
3.1 x 10-3 m
O 2.0 x 10-2 m
2.0 x 10-3 m
Answer:
B. 3.12 x [tex]10^{-3}[/tex] m
Explanation:
From the given picture, it can be deduced that;
the diameter of the image of lumen = 25.0 mm
= 25.0 ÷ 1000
= 0.025 m
And,
magnification = [tex]\frac{diameter of the image of lumen}{actual diameter of lumen}[/tex]
But magnification = 8,and diameter of the image of lumen = 0.025 m.
So that;
8 = [tex]\frac{0.025}{actual diameter of lumen}[/tex]
⇒ actual diameter of lumen = [tex]\frac{0.025}{8}[/tex]
= 0.003125
Actual diameter of lumen of the blood vessel is 3.12 x [tex]10^{-3}[/tex] m.

Which type of reproduction is responsible for genetic variation?
Answer:
sexual reproduction
Explanation:
Sexual reproduction results in infinite possibilities of genetic variation. In other words, sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other.
Other reproductions like asexual, budding or fragmentation don't produce genetic variation.
The type of reproduction is responsible for genetic variation is - sexual reproduction.
Sexual reproduction is combining genetic information from two individuals, by the fusion of gametes such as sperm and egg, called fertilization which generates more genetic variation, by the process like the combination of alleles and crossing over.
Parents and offsprings are not identical in this reproduction type, however, they are genetically similar.Fusion or combination of two different parent's gametes.There is recombination take place which causes genetic variations as well.Thus, the correct answer that is responsible for genetic variation is - sexual reproduction.
