Fossils can provide information about when life forms existed.
Fossils are the undecayed remains of the once living organisms. These remain preserved inside the heap of sediments. The deeper the strata the oldest is the organism once existed. This is indicative of the evolution of the organism from the ancestor to the modern day organisms.Hence, fossils provide information related to the evolutionary process.

A ______occurs when the Earth casts a shadow that partially or fully covers the Moon
O lunar eclipse
O summer solstice
O solar eclipse
Answer:
Lunar eclipse
Explanation:
During a lunar eclipse, the earth enters between the sun and the moon, thus preventing sunlight from reaching the moon. There are two types of lunar eclipses: A total lunar eclipse occurs when the moon and the sun are on opposite sides of the earth. When only part of the earth's shadow covers the moon, a partial lunar eclipse will occur. In some cases, it is called a blood moon, similar to the blood moon that occurs this month.

Which of the following is not a health risk associated with ozone?
A) skin cancer
B) cataracts
C) obesity
D) respiratory illneses
Answer:
obesity
Explanation:
The following that is not a health risk associated with ozone is obesity. The correct option is C.
What is ozone?Ozone is a trioxygen inorganic molecule that is of pale blue color. The ozone layer is present in the stratosphere of the atmosphere. It absorbs the UV rays coming from the sun. Thus, it is a protective layer that saves from UV rays.
UV rays are harmful rays that affect health. It creates skin problems and many other health problems. So the ozone layer protects us from UC radiation, it acts as a shield.
Obesity is a condition in which the body becomes fat. It happens with the accumulation of fat in the body. This does not occur with UV rays. It occurs due to food. So this will not be a health risk associated with ozone.
Thus, the correct option is C. obesity.

Explain why a topographic map has a key.
Topographic maps represent the locations of geographical features, such as hills and valleys.
What do you mean by topographic maps?Topographic maps use contour lines to show different elevations on a map. A contour line is a type of isoline; in this case, a line of equal elevation.
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines.
A topographic map is a detailed and accurate illustration of man-made and natural features on the ground such as roads, railways, power transmission lines, contours, elevations, rivers, lakes.

Maintaining homeostasis keeps the internal environment in the body functioning properly. Many organ systems work together and maintain energy homeostasis. The digestive system is concerned with processing the food that we take in to provide essential nutrients to the rest of the body. Which of these body systems works most directly with the digestive system in the absorption of nutrients?
A) urinary system
B) endocrine system
C) respiratory system
D) cardiovascular system
Answer:
D
Explanation:
However, the organ systems also work together to help the body maintain homeostasis. For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance. The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure.
Using the allele symbols in the table, identify the genotype of a guinea pig that is recessive for hair length, heterozygous for hair color, and homzygous dominant for hair texture.
Answer:
Hair length: hh
Hair color: Bb
Hair Texture: RR
Explanation:
In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.
The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from homzygous.
The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous dominant, which means there will be two of the same dominant alleles, so, RR.

Overfishing decreases the population of trout living in a river.
What would also decline because of the decreasing number of trout?
A mayflies that are part of the trout's diet
B. eels that compete with the trout for food
C. birds that use the trout as a source of food
D. fish that lay eggs that are eaten by the trout
Answer:
C. birds that use the trout as a source of food
Explanation:
Living organisms feed on one another in their natural environment in order to obtain energy for their various activities. According to this question, overfishing by humans decreases the population of trout living in a particular river.
This means that in that aquatic ecosystem (river), the population of organisms that feed on trout as a source of energy will also decrease. In this case, it is the birds. Hence, birds that use the trout as a source of food.
Answer:C
Explanation:
Because birds use that as a source of food.

Help me past due Write down what you think will happen to the density of water if you add salt or sugar.
Answer:
If I add sugar or salt, the water's density will increase.
Explanation:
Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass, v for volume.
If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.
We can use numbers to understand it better.
Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l
δ= 1g/l1t
δ= 1 g/lt
Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.
δ= 2g/1lt
δ= 2g/lt
We can see that the density increased when the mass increased.
