g Consider a culture medium such as mannitol salt agar (MSA) on which only gram-positive organisms such as Staphylococcus sp. Colonies can grow due to an elevated NaCl level. A yellow halo surrounds some colonies on the medium, indicating they are able to ferment the mannitol sugar, decreasing the pH and changing the color of a pH indicator chemical. This type of medium would be referred to as:
Answer:
Selective and differential medium
Explanation:
The type of medium described in the illustration would be referred to as a selective and differential medium.
There are basically 6 types of growth media for microbes based on the chemical composition of the medium;
Enrich media: media that are enriched by substances such as blood, egg, etc. E.g. blood agar.Basal media: media that can be used to culture organisms without the addition of any substance. E.g nutrient agar.Selective media: media that selectively favors the growth of one organism or a group of organisms over the others due to its contents. E.g. Mannitol Salt Agar, McConkey agar, etc.Differential media: media that has the potential to change color with respect to a particular organism. E.g Mannitol salt agar.Transport media: media that are used to transport organisms due to the fact that they cannot be cultured where they are collected. E.g Stuart mediumStorage media: media used to store organisms for future uses. E.g saline mediumMannitol salt agar has the capacity to favor the growth of a particular organism by indicating a color change. Hence, it is referred to as a selective and deferential medium.

Populations of organisms that exhibit a high degree of variation have a greater chance for survival than populations of organisms that show little variation. This statement is
-always true
-usually true
-rarely true
-never true
Answer:
Explanation:
Always trye
Populations of organisms that exhibit a high degree of variation have a greater chance of survival than populations of organisms that show little variation. This statement is usually true. Thus, the correct option will be B.
What is variation in organisms?Variation can be defined as any kind of difference between the different individuals in a species or group of organisms of any type of species. Mutations are the ultimate source of genetic variation, however the mechanisms such as sexual reproduction and the genetic flow can also contribute to mutation as well.
Evolutionary processes are the processes which are based on the selection of variations in a species by environmental variables. These differences may result in higher than usual survival benefits for the individuals as a result of positive trait adoption in an organism, or they may contribute to the genetic drift. Hence, all the variations in an organism have an equal chance of survival.
Therefore, the correct option will be B.

(surface tension, cohesion, polar, hydrogen bonding).
Water molecules share the electrons unequally causing it to be a_____ molecule. This allows_____ to form
between water molecules. The water molecules join together
through the process of_____
The cohesive forces of water
allows a thin film to form called____. This allows
water striders to be able to walk on top of water.
I NEED HELP NOWW
Answer:
1. Polar 2. Hydrogen bonding 3. Cohesion 4. Surface tension
Explanation:
1. Water is a polar molecules due to the presence of unbalanced charges in its covalent bond.
2. This unbalanced charges causes the molecules to be polar and thus form hydrogen bonds with nearby molecules due to their opposite charges. The hydrogen atom carries the positive charge while the oxygen atom carries the negative charge. The opposing charges thus causes hydrogen and oxygen atoms in nearby molecules to be attracted to each other.
3. This attraction of the water molecules to each other is called cohesion. Cohesion is the force of attraction between similar molecules and this force of attraction is called a cohesive force.
4. Since the water molecules are attracted to each other due to a cohesive force, this cohesive force causes a thin film to form called surface tension. Thus, surface tension is the ability of the surface of a liquid to resist external forces due to cohesive forces in its molecules and thus form a thin film.

Mechanical weathering
Chemical weathering
Deposition
Erosion
Answer:
Chemical weathering
Explanation:
Chemical weathering is the process when rain chemicals react with rocks and minerals. In this process, the rocks are weakened. This chemical happening provokes the chemical reaction in the rock or in the mineral.
Chemical weathering is a spontaneous process and it leads to a more stable state for natural materials under a given set of conditions.

How is an occluded front different from a cold front?
a) Warm air is pushed up during an occluded front, while cold air moves quickly during a cold front.
b) Occluded fronts cause warm air to feel dry, while cold fronts cause ground temperatures to feel cooler.
c) Warm air moves slowly during an occluded front, while cold air is cut off from the ground in a cold front.
d) Occluded fronts cause rapid changes in weather conditions, while cold fronts cause widespread cloud formation.
Answer:
A cold front forms at the leading edge of the colder air mass the cold front can bring thunderstorm in the region whereas the occluded front can bring strong winds and precipitation. so its probably d
Occluded fronts cause rapid changes in weather conditions, while cold fronts cause widespread cloud formation. Therefore, option (D) is correct.
What are occluded fronts?Because of their different densities, large masses of warm air and cold air do not mix when they come into contact with one another. They instead organize themselves into a front that is typically hundreds of miles long. When a warm air mass is sandwiched in between two cold air masses, the result is a phenomenon known as an occluded front. The mass of warm air rises as the masses of cool air push against one another and meet in the middle. The warm air mass is occluded, which literally means "cut off," from the ground, and pushed upward, which causes the temperature to drop. These types of fronts are known to bring blustery winds and significant precipitation.
Occluded fronts typically develop near low pressure areas that have reached their mature state.

Explain how iron band formations are
evidence for the evolution of Earth’s
atmosphere.
Answer:
Photosynthetic organisms were making oxygen, but it reacted with the iron dissolved in seawater to form iron oxide minerals on the ocean floor, creating banded iron formations. ... The oxygen that is now in the Earth's atmosphere was not there at the beginning.
Explanation:
Band formations are thought to develop from cyanobacteria. It was developed as product of cyanobacteria photosynthesis.
What is the other name of cyanobacteria ?The other name of cyanobacteria is blue green algae.
The oceans must change between aerobic and anoxic situations. This characteristic makes banded iron development of direct indicators of oceanic oxygen levels, providing us with a data of Earth's oxygenation.
Banded iron formations are brought to have formed in sea water as the consequence of oxygen production by photosynthetic cyanobacteria. The oxygen joined with dissolved iron in Earth's oceans to form insoluble iron oxides which precipitated out forming a thin layer on the ocean floor.

C. Salt crystals will form on the leaves as water evaporates on the leaf surface.
D. Water would leave the large vacuole of the cell and the plant will droop.
Answer:
option D
Explanation:
the plant will lose water because water moves out of the cell and the vacuole will leave the cell
Water would leave the large vacuole of the cell and the plant will droop if it was watered with salty water.
What is Vacuole?This is referred to as an organelle within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid.
