Answer:
B. passed through levels A, B, and C to organisms
Explanation:
DDT is an insecticide that passed through the food chain from one trophic level to the next.
The concentration of DDT increases with the each trophic level in food chain and the amount of toxin increases as passes from A to B, B to C, and C to D where D has the higher concentration of DDT as it is the higher trophic level than A, B, and C.
Hence, the correct answer is "B. passed through levels A, B, and C to organisms".

B. internal stimulus, external stimulus
C. chemical signal, display
D. association, condition
Answer:
I believe is C. I might be wrong
Explanation:
¯\_(ツ)_/¯
A change in an organism's body is an internal stimulus, while a change in the environment is an external stimulus. Thus, the correct option is B.
What is the Environment?An environment may be defined as anything which is present in the surrounding of living entities through which it interacts for various purposes.
There are a lot of alterations in the body of an organism with respect to time. Apart from organisms, a lot of changes have also occurred in an environment gradually and continuously.
Changes in the organism's body are internal so it is called internal stimulus, while alterations in the environment are externally made so they are called external stimulus.
Therefore, the correct option for this question is B.

In the image, the arrow Is pointing to a celestial object. Which attribute disqualifies the object from being a planet?
A. It appears to have no moons.
B. It is spherical in shape.
C. Its neighborhood is not clear.
D. It has horizontal bands on its surface.
The correct answer is C. Its neighborhood is not clear.
Explanation:
One of the key features of a planet is that it clears its neighborhood; this means the planet gravitational force is strong enough that there are no other celestial bodies on its orbit or next to it except by its moons or satellites. This does not occur in the image presented because there are smaller celestial bodies near to the main or bigger celestial body. This likely occurs if the celestial body is not big enough to clear its neighborhood, and therefore it is not a planet.

When a bacterium such as E. coli is shifted from a warmer growth temperature to a cooler growth temperature, it compensates by
Question is incomplete, The complete question is as follows:
When a bacterium such as E. coli is shifted from a warmer growth temperature to a cooler growth temperature, it compensates by:
A) increasing its metabolic rate to generate more heat.
B) putting longer-chain fatty acids into its membranes.
C) putting more unsaturated fatty acids into its membranes.
D) shifting from aerobic to anaerobic metabolism.
E) synthesizing thicker membranes to insulate the cell.
Answer:
C) putting more unsaturated fatty acids into its membranes.
Explanation:
Bacteria has the ability to change the composition of fatty acid present in its cell membrane to compensate the change in temperature.
When bacterium E.Coli will shift from hight or warmer temperature to low or cooler temperature, it will put more unsaturated fatty acids into its membranes which will mintain the fluidity in the membrane.
Hence, the correct option is "C".
Distinguish between the 4 major modes of nutrition of prokaryotes and identify each modes energy source and carbon source as well as giving an example
The four major modes of nutrition in prokaryotes are photoautotrophic, chemoautotrophic, photoheterotrophic, and chemoheterotrophic. Their differences, energy source and carbon source are explained below:
WHAT ARE PROKARYOTES?
Prokaryotes are a group of organisms that do not have their genetic material enclosed in a membrane bound NUCLEUS. They include bacteria, archeae etc.METABOLISM IN PROKARYOTES:
All organisms, prokaryotes inclusive, need energy for their metabolic activities. They also need carbon. Hence, based on their carbon and energy source, prokaryotes can be:
Photoautotrophic: These are prokaryotic organisms that use carbon dioxide as their carbon source and light as their energy source. Example iscyanobacteria.
Chemoautotrophic: These are prokaryotic organisms that act on inorganic substances as energy source and use carbon dioxide as carbon source. Example is Nitrosomonas bacteria.Photoheterotrophic: These are prokaryotic organisms that use light as source of energy but obtain carbon from other organisms (organic sources). Examples are heliobacteria, sulfur bacteria.Chemoheterotrophic: These are prokaryotic organisms that act on inorganic substances as energy source but derive their carbon source from organic compounds (other organisms).Learn more: https://brainly.com/question/6103977

Describe how protein functional groups can act as acid and base catalysts. How is it possible for a single amino acid side chain to function as both?
Answer:
By changing the transition state and pH of the medium
Explanation:
Enzymes are proteins that bind to their corresponding substrates at their active sites in order to form complexes that catalyze specific chemical reactions. A key feature of this process is the fact that both acid and base catalytic activities may be combined in the same reaction. The acceleration in the velocity of the enzymatic reaction due to the addition of acids and bases is known as acid–base catalysis, where the acid or base is not consumed during the reaction. For example, enzymes can partially transfer a proton to the medium, thus changing the transition state of the chemical reaction and also decreasing its pH.

Which of the following reflects the relationship between the posterior and the anterior pituitary glands?A. Unlike the posterior pituitary, the anterior pituitary makes and releases its own hormones without input from the hypothalamus.B. One is always a little behind.C. The anterior pituitary is under the control of the hypothalamus but the posterior pituitary is not.D. Unlike the posterior pituitary, the anterior pituitary releases "releasing or inhibiting" hormones.E. The posterior pituitary releases neurohormones and the anterior pituitary releases hormones.F. They are both extensions of the hypothalamus.
Answer:
The correct answer is - option E.
Explanation:
The anterior and posterior pituitary glands are he two distinct lobes of the pituitary gland which is controlled by the hypothalamus. The anterior lobe of the master gland is receives its signals from the specific neurons of the hypothalamus known as parvocellular neurons and produces six hormones that release in to circulation by itself.
On other hand the extension of the hypothalamus or the posterior pituitary gland receives the neurohormones from the hypothalamus such as oxytocin and ADH. Neurohormones are the hormones that are released by neurons of the posterior pituitary gland.
Thus, the correct answer is option E.
In meiosis, each centromere has a spindle fiber attached only to one side. In mitosis, each centromere has a spindle attached to how many sides?
Answer:
In mitosis, each centromere has a spindle attached on both side of centromere
Explanation:
In mitosis, each centromere has a spindle attached on both side of centromere because Spindle fibers move chromosomes during cell division by attaching to chromosome arms and centromeres. A centromere is the specific region of a chromosome where replicates are linked together.
Spindle fibers are active in mitosis and also meiosis and they move throughout the cells and also direct chromosomes to move to where they need to move to.
Spindle fibers function in centromere in mitosis and meiosis by pulling homologous chromosomes apart after they might have been replicated to prepare for division.

A researcher discovers that polar bears have very good insulation and very think hair (similar to pandas). However, they do not show the rest of the panda behaviors. For example, they have high daily energy expenditure and are very active. Why are the panda and polar bear so different
Answer:
Panda and polar bear have some similar characteristics but they also have differences in their behaviors such as polar bears have high daily energy expenditure and are very active while pandas are not.
The panda and polar bear so different because of the geographical difference where they live.
Polar bears are marine mammals and live in north pole perform swimming in north oceans and also move on ice flows, where they catch seals for survival, it makes them active and energetic.
While Pandas are found in China bamboo forests and are herbivores. They eat leaves from bamboo trees, for which they do not require to be more active and get their food easily. So, Pandas are not active as polar bears.
As the climate of North pole and China is cold, both polar bear and panda have very good insulation
