What is the main adaptive advantage of the C4 and CAM photosynthesis strategies over C3 photosynthesis?
a.They make it possible for the plant to use the Calvin cycle during the day.
b.They allow the plant to synthesize glucose without CO2.
c.They allow the plant to hold its breath and still perform photosynthesis.
d.They allow the plant to synthesize glucose under hot conditions.
Answer:
D. They allow the plant to synthesize glucose under hot conditions.
Explanation:
C4 and CAM photosynthesis strategies allow for plants to produce glucose in hot and dry conditions.
Plants such as cacti, which live in hot conditions, have the advantage from their C4 and CAM systems.
In contrast to C3 photosynthesis, C4 and CAM systems allow plants to get more CO2 from the air and help them conserve water.
This then allows them to efficiently create glucose with the CO2.
So, the correct answer is D.
Answer:
D. they allow the plant to synthesize glucose under hot conditions.

which of these is an example of an abiotic factor
A:creosote plant
B:rocky desert soil
C:kangaroo rat
D:coyote
Answer:
[tex]\boxed {\boxed {\sf B. \ Rocky \ desert \ soil}}[/tex]
Explanation:
An abiotic factor is a part of an ecosytem, but it is not alive. Some examples include water, rocks, sunlight, and the atmosphere.
On the other hand, a biotic factor is a living part of an ecosystem. Some examples are animals, plants, and fungi.
Let's look at the answer choices.
A creosote plant (choice A) kangaroo rat (choice C) and coyote (choice D) are all living organisms. Therefore, they must be biotic factors.
However, rocky desert soil (choice B) is not living. It's a part of the ecosystem, but since it's not alive it must be abiotic.

What is the function of the outer covering in fish?
1 Protects the fish from their environment
2 Supports the body and internal organs
3 Used for reproduction
4 Works with the muscles to allow movement
Answer:
Your answer is A,
Explanation: D can be argued for as well but those are the secondary functions of scales. Their main function is to protect the fish.
Many fish contain an outer covering of scales. Scales protect fish, much like a suit of armor. All fish have a dirty covering of mucus. This substance permits the fish to swim through the water with very little yawn and also makes it hard for other organism to adhere to the fish.
What are the functions of the parts of a fish?The dorsal and ventral fins mainly help fish to not move over onto their flanks.
The caudal fin is the main fin for propulsion to move the fish forward. The coupled fins help with steering, stopping and hovering.
Thus option "A" is correct, Protects the fish from their environment.

Outline the effect of the following mutations:
TAG-> TAT
TAC-> TCC
Answer:
TAG-> TAT >> sense mutation
TAC-> TCC >> missense mutation
Explanation:
A sense mutation is a type of mutation that changes a stop codon into a sense codon, thus producing an elongated protein. The TAG codon (UAG in the RNA) is a stop codon, while TAT (UAU) encodes for tyrosine, thereby TAG-> TAT is a sense mutation. On the other hand, a missense mutation is a type of point mutation where a single nucleotide change generates a new codon which encodes a different amino acid. In this case, the TAC codon (UAC) encodes for tyrosine, while TCC (UCC) codon encodes for serine, and therefore TAC-> TCC is a missense mutation (Tyr to Ser mutation).

A dry cement road is a diffuse reflector. When it rains, the water fills in all the little holes and cracks in the cement road and it becomes a smooth regular reflector. At night, when you are depending on the light from your headlights to show you the lines on the road, a wet road becomes much darker and it is more difficult to see the lines. Explain why this occurs.
Answer:
Because of reflection of light away from the marking
Explanation:
It is because the light from a vehicle falls on the road and its markings which then gets illuminated as light is reflected only in one direction.
But in case when the road is wet, light of vehicle reflects in different directions away from the markings on the road and hence they do not illuminate.
The reason why the given phenomenon about the effect of light and while driving is; Due to total internal reflection of light away from the marking.
What is reflection of light?Reflection of light is simply defined as the phenomenon where light is sent back after being incident on a surface.
Now, in this question, the light from a vehicle falls on the road and its markings and then gets illuminated as light is reflected only in one direction.
However, when the road is wet, the headlight of vehicles tend to reflect away from the markings on the road in different directions which make them not to illuminate.
Thus, we conclude that reason why the given phenomenon about the effect of light and water on driving is due to total internal reflection of light away from the marking.

The service box is an area on the court that 1 point the person serving must stand in. the ball must land in to be a playable serve. the person returning the serve must be standing in before a server can serve
Answer:
Both players on the serving doubles team have the opportunity to serve and score points until they commit a fault *(except for the first service sequence of each new game).
The first serve of each side-out is made from the right-hand court.
If a point is scored, the server switches sides and the server initiates the next serve from the left-hand court.
As subsequent points are scored, the server continues switching back and forth until a fault is committed and the first server loses the serve.
When the first server loses the serve the partner then serves from their correct side of the court (except for the first service sequence of the game*).
The second server continues serving until his team commits a fault and loses the serve to the opposing team.
Once the service goes to the opposition (at side out), the first serve is from the right-hand court and both players on that team have the opportunity to serve and score points until their team commits two faults.
In singles the server serves from the right-hand court when his or her score is even and from the left when the score is odd.

Pyramids depicting the number of organisms or biomass may be inverted, upright, or even diamond-shaped.
Energy pyramids, however, are always upright. Why?
Answer:
The correct answer is - as energy lost at every trophic level.
Explanation:
In any ecological ecosystem the energy pyramids always upright unlike other pyramids such as biomass showing the number of organisms, that can be diamond shape, inverted or upright.
The main reason behind this is due to the fact that it is only a pyramid in the ecosystem that always unidirectional in the food chain which is always some energy lost with an increase in the trophic level in the food chain. This loss of energy always gets back to the atmosphere in each step of the food chain.
As the energy is lost at every trophic level, the energy pyramids are always upright. A further explanation is below.
In whatsoever biological environment, the energy pyramid always seems to be straight, unlike some of the other pyramidal, including such biomass, which might be diamond-shaped, overturned, as well as upstanding.Essentially the food chain is simply a pyramid, and there is always some power loss as that of the primary consumers throughout the chain increases.
Thus the response above is right.

13-22 Aquaculturists (people who farm marine resources, typically in semi-enclosed areas off the coast) have development methods of growing various invertebrates as food sources, such as clams, mussels, and oysters. Other widely consumed species, such as squid, have never been successfully grown in controlled marine environments, and so they remain wild caught. Why
Answer: There are several problems associated with handling of the squid.
Explanation:
Squid is a deep sea creature which becomes enormously big in size and difficult in handling in artificial water body or aquaculture.
It consumes and requires huge amount of food in the pre-larval stages typically phytoplankton and it becomes difficult to provide such food to them.
The maintenance of temperature, and salinity for the squid in aquaculture is difficult.
The sticky arms of the squid adhere to the surface of tub or human handler making it difficult to handle and can be poisonous to humans too.
