which best describes what happens to stop during photosynthesis​

Answer:

1) Gases become more difficult to liquefy as the temperature increases because the kinetic energies of the particles that make up the gas also increase. The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied.

2)The compressor constricts the refrigerant vapor, raising its pressure, and pushes it into the coils on the outside of the refrigerator.  When the hot gas in the coils meets the cooler air temperature of the kitchen, it becomes a liquid. The refrigerant absorbs the heat inside the fridge, cooling down the air.

Explanation:

hope this helps you.

Answer:

1.  When a solid substance is heated, its temperature will rise until it reaches a critical temperature. At this point, the item won’t melt unless more heat is provided. This additional heat represents energy needed to change the state of the substance from solid to liquid. This energy loosens the ties of molecules, causing them to move faster. When enough heat energy is provided, the substance will change to the liquid state, but the temperature of the substance won’t change. The amount of heat energy required to change a unit of mass from a solid to a liquid without any change of temperature is the latent heat of fusion. If it’s necessary to increase the temperature of a melted substance, additional heat energy must be provided. The latent heat of vaporization is the amount of heat energy required to change a unit of mass of a liquid to a gas without a temperature change.

To condense a gas to a liquid, the gas must be cooled to the condensation point. After condensation, the liquid will have the same temperature as the gas; the temperature is still at the condensation point. To be cooled further, more heat energy should be released.

2.  The liquid refrigerant in the indoor coils picks up heat from the indoor air and evaporates. In the gaseous state, it’s pumped to the outdoor coils, where it releases vaporization heat and condenses to the liquid state. The heat is transferred to the outdoor air, and the liquid refrigerant continues to circulate to the indoor coils to repeat the cooling cycle.

D. Stabilizing selection

Explanation:

Stabilizing selection helps to prevent extreme trait characteristics and focuses on the non extreme ones to ensure that such traits are prevalent.

Due to the fact that there isn’t enough food for a large number of the offspring and also the risk of losing all the eggs to those who had a small amount of eggs, stability was achieved after some generations that ensures that there was a balance in ensuring the eggs weren’t too few and too many.

Answer:

The correct option is: a deficiency of dopamine in the substantia nigra.

Explanation:

The substantia nigra is the principal site involved in the physiopathology of Parkinson´s disease.

Cells from this area degenerate and die progressively causing important degeneration in the central nervous system. The cells that die -with no known reason- are those that produce dopamine and proportionate dopaminergic innervation to the encephalon. In fact, almost all the symptoms exhibited by patients with the disease can be explained by the lack of dopamine in the substantia nigra.  

This area uses the neurotransmitter to communicate neurons from the base ganglia. Ganglia are responsible of modulating and modifying movements.

The nigrostriatal system participates in planning and automatic execution of learned movements. When the ganglia activity decreases, so it does the amount and velocity of movements, something typical of the disease.  

Answer:

Conditional genes enable to study the gene function by manipulating the gene of interest

Explanation:

Conditional alleles are widely used in molecular genetics to study gene function in target tissues or developmental stages. A conditional allele can be produced by introducing two recombinase recognition sites (SRSs) at flanking regions of the target gene, thereby deletion/inversion of these sites induced by a specific recombinase will produce a null allele. Generally, conditional alleles are designed by introducing LoxP sites flanking the gene of interest; however, classical gene targeting methods (i.e., by homologous recombination) have been historically used in order to produce conditional alleles.

Explanation:

Answer:

See the answer below

Explanation:

Amphibians are not totally adapted to live on land because the aquatic environment is needed for several life processes such as reproduction, respiration, and sometimes, feeding.

The eggs of amphibians are without any protective shells and will suffer desiccation in the terrestrial environment. Hence, water is needed in order to protect the eggs. In addition, the male amphibians shed their sperm in the water close to the female eggs.

The young ones of amphibians are essentially aquatic and may not survive out of water for a long time because they only breathe gills - the lung is yet to develop or poorly developed at this stage. They have to grow and develop to a certain stage in water before they can start surviving on land.

Due to their reliance on an aquatic habitat for reproduction, amphibians relocated to a terrestrial environment but did not evolve the capacity to spend their entire lives on land.

Amphibians often lay their eggs in water or other damp places since these conditions are essential for a proper embryonic development.

Since the eggs don't have a shell to protect them, they need a moist environment to prevent desiccation and promote gas exchange.

The frog is an illustration of an amphibian that is still reliant on an aquatic habitat. In water, frogs lay their eggs, which develop into aquatic tadpoles.

Thus, even though they can live and thrive on land for a substantial portion of their life cycle, amphibians are dependent on an aquatic environment due to their reproductive and metabolic traits.

Answer:

DNA from male & female of same species

Explanation:

According to base-pairing rules, adenine (A) always bonds to thymine (T) or Uracil (U), while guanine (G) always bonds to cytosine (C). Nucleic acid hybridization is a process produced by base-pairing complementary between two different DNA (or DNA and RNA) single-stranded molecules to give a hybrid double helix. In consequence, and since hybridization involves base-pairing from different sources, the pairing between DNA strands belonging to male and female of the same species is not considered as a process of hybridization.

The following are the steps illustrating the production of an action potential via the voltage-regulated channels:  

1. First, the hypo-polarization of the stimulus takes place.  

2. The opening of sodium cation gates takes place, resulting in the diffusion of sodium ions within the cell.  

3. The threshold is attained at -55 mV, positive feedback takes place, that is, more opening of Na+ gates takes place, and thus, more diffusion of Na+ ions takes place within the cell resulting in depolarization.  

4. The closing of Na+ ions gates occurs and the opening of K+ ions takes place.  

5. Repolarization occurs resulting in hyperpolarization.  

6. With the closing of K+ gates, the returning of resting membrane potential takes place.

Green pigmented plastids that function in photosynthesis are called Chloroplasts

yes the trees maintain the balance between gases in the air

Photosynthesis absorbs and stores carbon dioxide in trees' wood. Trees and plants store carbon dioxide throughout their lives, slowing the gas's buildup in our atmosphere, which is quickly warming our world. Therefore, its true.

By supplying oxygen, enhancing air quality, reducing climate change, conserving water, maintaining soil, and fostering animals, trees benefit their surroundings. Trees absorb carbon dioxide during photosynthesis and turn it into the oxygen we breathe.

By reducing the effects of the sun, rain, and wind, trees regulate climate. The radiant energy of the sun is absorbed and filtered by leaves, keeping things cool in the summer. By acting as a windbreak, trees also keep the heat in. They not only control wind direction and speed, but also protect us from precipitation such as hail, sleet, and rain. By maintaining low levels of carbon dioxide, trees also lower air temperatures and lessen the intensity of the greenhouse effect.
