Answer:
seminiferous tubules
Explanation:
Seminiferous tubules are coiled tubes where sperm cells are produced by a process referred to as spermatogenesis. These tubes are located in the testes or testicles (i.e., male reproductive glands/gonads). Each testicle contains approximately 250 compartments known as testicular lobules, while each testicular lobule has 1 to 4 seminiferous tubules which converge to form a single straight tubule. Once sperm cells mature, they travel through the seminiferous tubules to be stored in a coiled tube called the epididymis.
Complex food molecules that are consumed by organisms must be broken down in order to be used by cells to support growth or release energy.
True

Answer:True
Explanation:
The complex molecules are broken down by the digestive system. If the molecules were not to be broken down they would block the system

Answer:
B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules
Explanation:
DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.
In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.

When a mechanical wave is reflected, it ______________ off the medium and then travels in a ______________ direction. ______________ is an application that uses sound wave reflection to determine how deep water is. A third way mechanical waves react to a medium is _______________. When a mechanical wave is absorbed, it remains __________________ a medium and is not transmitted to another medium.
Answer:
Mechanical waves react to different mediums in different ways. Some mechanical waves are TRANSMITTED through a medium, meaning they pass through the medium.
The way in which waves are transmitted depends upon the type of material. In SOLIDS, mechanical waves travel rapidly, because the molecules are DENSELY packed. In liquids and air, however, mechanical waves travel more SLOWLY, because the molecules are spread farther apart.
Other mechanical waves are reflected off a medium. When a mechanical wave is reflected, it BOUNCES off the medium and then travels in a DIFFERENT direction. SONAR is an application that uses sound wave reflection to determine how deep water is.
A third way mechanical waves react to a medium is ABSORPTION. When a mechanical wave is absorbed, it remains WITHIN a medium and is not transmitted to another medium.

Explanation:
1. Which of the following describes the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration?
-Gross Primary productivity
-Biomass
-Net Primary productivity
0r
-Primary productivity
2. Suppose a plant is eaten by a mouse, the mouse is consumed by a snake, and the snake is in turn consumed by a hawk. What could be assumed about the level of available organic matter in the mouse versus the plant?
-There will be less organic matter available.
-There will be more organic matter available.
-Organic matter does not transfer between the plant and the mouse.
0r
-They both have the same amount of organic matter.
3. How does biomass change from lower to higher trophic levels?
-It fluctuates.
-It increases.
-It decreases.
0r
-It stays the same.
4. The incomplete burning of _____ in gasoline is known to create black carbon and contribute to global warming.
-ethanol
-methane
-carbon
0r
-carbon dioxide
5. Why are there less secondary consumers in an ecosystem than producers?
-Around 90% of energy from one trophic level to the next is available.
-There is less land to use for habitat after the producers grow.
-More tertiary consumers will eat secondary consumers over producers.
0r
-There isn’t enough energy available to support more secondary consumers.
Net primary productivity is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration.
When a plant is eaten by a mouse, the mouse is consumed by a snake, and the snake is in turn consumed by a hawk. In this case, there will be less organic matter available.
Biomass change from lower to higher trophic levels by decreasing.
The incomplete burning of ethanol in gasoline is known to create black carbon and contribute to global warming.
There is less secondary consumers in an ecosystem than producers because there isn’t enough energy available to support more secondary consumers.
It should be noted that global warming brings about the increase in the temperature around the world.

true or false:
Fish are considered carbon-based organism
Answer:
Its how you see it.
Explanation:
1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.
2.All life on earth can be thought of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.

Answer:
The process of that same framework in question is defined below.
Explanation:
The DNA was indeed prepared by mixing with either a dye as well as a radioisotope which enables the gel to have been recognized. The specific filaments would then be differentiated from one another DNA electrophoresis. The procedure occurs with the injection including its completely separate genetic code into boreholes that have already been reduced either at the final moment including its gel pavement.

1. A dominant gene (A) causes yellow color in rats, the dominant allele on another independent gene (R) produces black coat color. When the two dominants occur together (A_ R_) they interact to produce gray coat color. Rats of the genotype aa are cream-colored. If a gray male and a yellow female, when mated, produce offspring approximately 3/8 of which are yellow, 3/8 gray and 1/8 cream, and 1/8 black, what are the genotypes of the parents

The correct answer is - add a few bases for DNA polymerase
Explanation:
A short extended nucleic acid composed of ssRNA molecule. This is a molecule that synthesize a primer initialy and later again lay down a primer after the opening of replication fork by DNA helicase.
It sysntheisze before and after the helicase and follow the helicase in order to prepare for the replication process. Thus, adding a few bases for DNA polymerase is main job of RNA primase.

If there will be changes on trophic levels, what will be the effects on the ecosystem?
Answer:
It can significantly alter the homeostasis of the ecosystem
Explanation:
The trophic level is the position that occupies a given organism/ population/species in the food web. In a food web, the trophic levels are organized into a first category (formed by primary producers, e.g., plants), a second level (primary consumers, e.g., herbivores), and subsequent categories (predators, e.g., carnivores). The abrupt change in the number of organisms belonging to the same trophic level generally has a negative effect on the ecosystem by modifying the trophic structure of communities. For example, decreasing the number of producers will produce a decrease in the number of primary consumers, thereby altering the homeostasis (equilibrium) of the entire ecosystem. On some occasions, it may eventually lead to the extinction of populations and species.
