3) Where are the anti-biotics the least concentrated? [1pt]
Answer: Every microbiologist eventually has to grow bacteria in the lab. Bacterial culturing is the process of growing bacteria.The media must contain everything the bacteria need to survive and can be liquid or solid. Agar is added to hot liquid media to make a gel used for culturing in plates, tubes, slants, and stabs.

What are the functions of agar?Agar is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from ogonori and "tengusa".
Agar (agar agar) is a gelatinous substance that is extracted from seaweed and processed into flakes, powders and sheets. It is commonly used in Asian cuisines and as a flavorless vegan substitute for gelatin.
Agar helps gel, stabilize, texturize and thicken beverages, baked goods, confectioneries, dairy products, dressings, meat products and sauces.

Does anyone know this?
which part of thr mitochondrion does an electron transport chain occur?
Answer:
Electron transport chain is the series of the cycle of the transfer of electrons from the one complex to other complex of the cycle. Both oxidation and redo reaction occurs in the electron transport chain.
The process of electron transport chain occurs in the inner mitochondrial membrane. All the complexes and the substrate of the cycle are embedded in the inner mitochondrial membrane. ATP is produced by this cycle located in the inner mitochondrial membrane.

Climate change (an abiotic factor) has slowly decreased habitat for the arctic seals. Predict how a reduction in habitat could change the capture efficiency of the killer whales. How would this affect the carrying capacities for both the whales and the seals?
If another source of prey were available to the whales, what changes in population size would you expect for the seals and the whales?
What are the limitations of the population dynamics lab? Is the lab activity a realistic representation of an arctic marine ecosystem?
Answer
#1. A reduction in habitat for arctic seals will reduce the population of arctic seals. This will reduce the capture efficiency for killer whales preying on arctic seals because there will be fewer to capture. A reduction in habitat for arctic seals will lower the carrying capacity for arctic seals because there is less habitat. A reduction in arctic seals, the food for killer whales, will reduce the carrying capacity for killer whales, unless there is a substitute source of food.
#2. If there is another source of food for killer whales, the population of killer whales will probably remain the same, if they were at their carrying capacity and their habitat remains the same. If there is another source of food for killer whales, the population of arctic seals will still decrease, because the habitat for arctic seals has decreased, and habitat is independent of predator population.
#3. There are many limitations on any simulation. The computer only uses the parameters in the program, so changes in ocean temperature, weather patterns, salinity changes, food supply, habitat, interaction with other species and presence of plants and zooplankton are not considered. All of those can change and change the results.
Explanation:

During _________, energy from the Sun is stored in the bonds of sugar molecules.
Answer:
Photosynthesis.
Explanation:
"Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth (Global Change)."
Hope this helped! :)))
Answer:
PHOTOSYNTHESIS
Explanation:
Some bacterial cells secrete a chemical that allows other bacterial cells to determine the density of bacterial cells in the area. They use this to determine if their population is large enough to begin certain functions, like forming a protective biofilm together.
Based on this type of chemical signaling, which of the following demonstrates the same type of chemical signaling?
A. B cells engage in cell-to-cell recognition with helper T cells, exchanging antigen information the B cell has on its cell surface.
B. Cells that secrete oxytocin also use oxytocin for autocrine signaling, helping it to down-regulate production when needed.
C. During development, human nerve cells participate in paracrine signaling to determine what other nerve-cell types are in the area to adjust their placement.
D. Some animal cells can form junctions with other animal cells to directly share information.

2. List the inputs and outputs of
photosynthesis. What part(s) of
the plant are responsible for
taking in each of the inputs?
Answer:
Inputs: carbon dioxide (CO2) and water (H2O)
Output: Sugar (C6H12O6) and oxygen
- Roots take in water
- Leaves take in carbondioxide
Explanation:
Photosynthesis is a unique metabolic process undergone by only set of organisms called AUTOTROPHS. Autotrophs are capable of synthesizing their own food by capturing light energy (from sun) and using it to make food (sugars).
This photosynthetic process requires certain substances called INPUTS, which are basically carbon dioxide (CO2) and water (H2O) and give out products called OUTPUTS, which are sugars and oxygen gas.
- The CO2 input is taken in by the plant via the stomata on its leaves while the water (H2O) is absorbed by the roots of the plant.

is photosynthesis really essential for our survival? please explain
Why does photosynthesis needs cellular respiration?
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

which part of the blood transports insulin to its target organs?
Answer:
endocrine glands
Explanation:
The part of the blood that transports insulin to its target organs is plasma
BLOOD:
The blood is a crucial part of the circulatory system. It functions majorly as a carrier tissue in the body. The blood carries substances like hormones, glucose, carbon dioxide, oxygen etc. from one location to the other. The blood is, however, a tissue made up of different cells and components namely: erythrocytes, leucocytes, plasma, platelets. The plasma component of the blood is its liquid part and makes up majority of blood's volume. The plasma is the medium in which most substances in the body dissolves and transported. Therefore, the part of the blood that transports insulin to its target organs is plasma.Learn more:https://brainly.com/question/18207038?referrer=searchResults
