Answer:
a selective medium, a differential medium, and a complex medium
Explanation:
EMB Agar (Eosin Methylene Blue Agar) is both a selective and differential culture medium that slightly inhibits Gram-positive bacteria and can be used to distinguish bacteria capable of fermenting lactose from those that are unable to ferment this disaccharide. This medium is commonly used for isolation and differentiation of coliforms (i.e., bacteria found in the soil and water samples) and fecal coliforms (bacteria found in the gut and feces samples). In EMB agar, lactose-fermenting-gram-negative bacteria (e.g., E. coli) will form colored colonies, while non-lactose-fermenting-gram-negative bacteria will form colorless colonies (e.g., Salmonella). EMB agar is composed of lactose, gelatin, methylene blue dye and eosin Y dye ( a xanthene dye) .

Explanation:
The user needs to drag the slider bar in an upwards direction in order to completely melt away a body layer when in the dissection study area.
True or False
Answer:
False
Explanation:
During the dissection study the body is kept in laying position so that the scientist can easily perform experiments. The body is kept in laying position not in upward position. The body in upward position will have gravitational effect on the fluids and the body layer will not melt.

Describe how epinephrine has different effects in different target tissues
Answer:
Epinephrine binds to receptors on some smooth muscles (ex: around arterioles) → Ca++ released from ER → intracellular Ca++ up → stimulates contraction. c. Epinephrine binds to receptors on some smooth muscles (ex: around bronchioles) → phosphorylates protein needed for response to Ca++, preventing response.

Where do the thickest deposits of terrigenous sediment typically form?
A. deep-ocean trenches, such as the Mariana Trench
B. mid-ocean ridges
C. abyssal plains
D. continental margins near the mouths of rivers
Answer: D. continental margins near the mouths of rivers
Explanation:
Terrigenous sediments are those that are formed via processes on land as opposed to in water. They result mostly from the erosion of rocks and yet make up 20% of all ocean sediments.
Continental margins near the mouths of rivers contain the thickest deposits of this sediments as they are closest to land which is the source. It is made more convenient by the presence of rivers bringing the sediments to them when the rocks are eroded.

In 1929, Edwin Hubble observed the velocity at which galaxies were moving away from the Milky Way. The graph below shows the relationship between this velocity and the distance those galaxies were from the Milky Way.
What conclusion can be drawn from Hubble’s data?
Objects that are closer are moving slower, suggesting that the Universe is shrinking.
Objects that are closer are moving faster, suggesting that the Universe is expanding.
Objects that are farther away are moving faster, suggesting that the Universe is shrinking.

A scientist is researching two different traits in an insect: body texture and color. Smooth body (B) is dominant to bumpy body (b), and gray (G) is dominant to white (g). A BbGg and a bbgg insect mate and produce the following 480 offspring: Phenotype Number of Offspring Smooth, gray 119 Bumpy, white 117 Smooth, white 123 Bumpy, gray 121 What type of inheritance is displayed from these offspring
Answer:
Independent assortment
Explanation:
The type of inheritance displayed by the offspring is a simple independent assortment inheritance according to Mendelian law.
The result of crossing BbGg and bbgg is as follows (see the attached image)
4 BbGg smooth and gray
4 Bbgg smooth and white
4 bbGg bumpy and gray
4 bbgg bumpy and white
The phenotype ratio from the cross is 1:1:1:1 as far as the independent assortment is concerned.
Now, looking at the population of each phenotype from the cross
Smooth, gray 119
Smooth, white 123
Bumpy, gray 121
Bumpy, white 117
119:123:121:117 is approximately equal to 1:1:1:1.
Hence, the cross agrees with Mendel's law of independent assortment of genes.
Agriculture has only a positive impact on the land.
True or False?
False; Agriculture can negatively impact the environment when fertilizer enters the water, contaminating it. Agriculture can also lead to deforestation, the lack of trees will lead to erosion.

Why do viruses not fit easily into the broadest taxonomic category, life? (Choose all that apply)
1. They are not made of cells.
2. They have a capsid.
3. They do not reproduce on their own.
4. They do not respond to stimuli.
Answer:
viruses are not fit into broadest taxanomic system because:
they are not cells
they do not reproduce their own
they do not respond to stimuli.
Explanation:
viruses have capsid and are not cells. to be a cell they must have a cell membrane while viruses lack cell wall. they replicate by using the host machinary in which they are causing infection. they are acellular and obligate intracellular parasites of anials plants fungi and bacteria.
Answer:
they are not cells
they do not reproduce their own
they do not respond to stimuli

which of these is an adaptation that helps fish survive in the bathyal and abyssal zones?
A dark-colored body
B
A yellow or orange body
с
Reduced sense of smell
A. Dark-colored body
In the abyssal and bathyal zones, it is so deep that light does not penetrate the water, so it is completely dark. A dark-colored body helps fish survive as it camouflages them.
