someone help me pleaseeee
Answer:
c
Explanation:
the question is asking about the energies. when the two cars are moving towards each other they are accelerating meaning they have kinetic energy. when they collide; on rebounding, the car regains a smaller amount of kinetic energy – this time travelling backwards. So the overall process is that kinetic energy becomes heat and spring potential energy, which results in heat, smaller kinetic energy and, hopefully, surviving occupants. so the speed of the car before and after will show the energy change
Which of the following is a true description of the green alga Spirogyra sp.?
Select one:
a. The alga has a branched, multicellular, filamentous habit.
b. The chloroplast with its pyrenoids is arranged spirally throughout each filament.
c. Most of the interior of each cell is occupied by cytoplasm.
d. Gametic meiosis takes place via the process of conjugation between filaments.
which of the following is NOT a nucleic acid ?
a. DNA
b. mRNA
c. tRNA
d. Protein
Answer:
reverse transcriptase
Explanation:
The following is NOT a nucleic acid is - d. protein as it is a different macronutrient or macromolecule to nucleic acid.
Nucleic acids are macromolecules of a special class found in all living organisms and also in viruses. There are two types of major nucleic acids, DNA or deoxyribose nucleic acid and RNA or ribose nucleic acid.
Nucleic acids play a role in genetic materialnucleic acid helps in protein synthesisRNA is mainly three types mRNA, messenger RNA, tRNA transfer RNA, and rRNA ribosomal RNA.DNA is normally double-strandedProtein on other hand is a different class of macromolecules that perform many roles in the cell such as, structure, function, and regulation.
Thus, the correct answer is - D. protein.

How does movement of the legs affect the gills of crabs?
Answer:
The beating or fanning movements of three pairs of maxilliped flagella in crabs and crayfish modify exhalent gill currents while drawing water over chemoreceptors on the head. They play an integral part both in signalling by distributing urine odours, and in active chemosensation.

What type of plate boundary occurs where two plates move away from one
another?
Answer:
Divergent Boundary
Explanation:
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.

How does the speed of flowing water affect its ability to erode
HELP PLZZZ!!!
Answer:
Moving water also picks up and carries particles of soil and rock. The ability to erode is affected by the velocity, or speed, of the water. ... As water slows, larger particles are deposited. As the water slows even more, smaller particles are deposited.Explanation:

Power plants (especially fossil-fuel based coal and gas-fired units) are frequently mentioned sources of environmental problems. List three specific types of outputs to the environment resulting from these fossil plants. Which other parts of the life cycle of producing electricity from fossil plants also contribute to these problems
Answer:
Effects of Conventional (fossil fuels & gas fired) power plants : Air pollution, Water Pollution, Land Degradation
Explanation:
Fossil power plants, that use fossil fuels for electricity generation, have various ill environmental effects
Air Pollution - Coal Power Plants emit many polluting gases into environment. Like Sulphur Dioxide, Carbon Monoxide etc, Nitrogen Oxides. The last gas is majorly emitted during process of nitrogen combustion.
Water Pollution - Coal washing process before placing it in boiler (for heat generated electricity) , circulates the same unclean water into water bodies & groundwater.
Land Degradation - The after process disposal mechanism implies untreated water & air pollutants released indiscriminately. This adversely effects the land quality & the wildlife.

Explanation:
The ability to taste the chemical PTC is determined by a single gene in humans with the ability to taste given by the dominant allele T and the inability to taste by the recessive allele t. Suppose two heterozygous tasters (Tt) have a large family. What is the likelihood that their first child will be a taster
Answer:
75%
Explanation:
This question involves a single gene coding for the ability to taste the chemical PTC. The allele coding for the ability to taste (T) is dominant over the allele coding for the inability to taste (t). This means that an heterozygous individual will have the ability to taste PTC.
According to this question, if two heterozygous tasters (Tt) cross to have a large family i.e. Tt × Tt, the following gametes will be produced by each parent;
Tt = T and t
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
TT, Tt, Tt - Tasters (3/4 or 75%)
tt - Non-taster (1/4 or 25%)
Note that based on the question asked, there is a 75% probability that their first child will be a taster because there is equal segregation of alleles into gametes.

Answer:
Water puts pressure depends on their amount.
Explanation:
On the left side, there is less quantity of water in the tube that put less pressure on the bag present at the bottom and the bag swells slightly while on the other hand, on the right side, there is more amount of water in the tube that puts large pressure on the bag located at the bottom and as a result it swells higher than the other bag so we can conclude that more water puts more pressure and less water puts less pressure.
This sequence best represents
A) an arid region that experienced mostly uplifting forces
B) an arid region that experienced mostly erosional forces
C) a humid region that experienced mostly uplifting forces
D) a humid region that experienced mostly erosional forces
The correct answer is B. An arid region that experienced mostly uplifting forces.
Explanation
According to the graph, it can be seen that 25 million years ago the illustrated area was arid and the earth's crust had a fracture that eroded to form a table 15 million years ago as shown in the second illustration. Later, it is shown how the erosion continued to act on this area until creating different plateaus and a plain in the present time. The key to understanding these illustrations are the layers of the earth's crust that are shown because it shows how some layers are disappearing or reducing their area while the lower layers are being exposed. Therefore, the correct answer is B. An arid region that experienced mostly uplifting forces.
1. What effect does air pressure have on wind movement?
2. What happens to the density of air as it is heated?
3. It’s a hot, sunny morning in a coastal town in South Florida. Warm air is rising up from the land. Large, puffy clouds are forming overhead. Which way do you think the wind will be moving this afternoon, and what do you think will happen to the temperature?
Answer:
1. The lower the air pressure the faster the wind the higher the air pressure the slower the winds
2. When the heat of the air increases the density of the air decreases.
3. The air above the ocean will, therefore, be warmer and of low pressure than that over land which will be cooler and of relatively higher pressure. Winds will, therefore, blow seawards because winds blow from high to low-pressure systems.
