A. Transpiration
B. Percolation
C. Precipitation
D. Condensation
Answer:
A. Transpiration
Explanation:
Transpiration occurs through the stomata of the leaves.
Hope it helps.
Transpiration is the term used when plants lose water through their leaves. transpiration is an important process for plants and for the Earth's water cycle, helping to regulate water balance, transport nutrients, and regulate temperature. Hence option A is correct.
What is transpiration?Transpiration is the process by which plants lose water from their leaves through tiny pores called stomata. Stomata are located on the underside of the leaves, and they allow water vapor to escape from the plant into the surrounding atmosphere. Transpiration is a vital process for plants as it helps to regulate their internal water balance and temperature.
During transpiration, water is drawn up from the soil through the plant's roots and into the leaves. Water is then released through the stomata as water vapor, which evaporates into the air. This process is driven by the plant's need to transport nutrients and minerals from the soil up to the leaves, and to regulate its internal temperature.
Transpiration also plays an important role in the global water cycle, as it contributes to the amount of water vapor in the atmosphere. This water vapor can then condense to form clouds, which can lead to precipitation in the form of rain or snow.
Hence option A is correct.

Answer:
Las hormonas activan vías de señalización celular, con lo cual regulando el crecimiento, metabolismo y reproducción del organismo
Explanation:
Las hormonas son moléculas mensajeras que circulan a través del torrente sanguíneo para llevar a cabo diferentes funciones. Estas moléculas se unen a receptores específicos presentes en la superficie de las células con la finalidad de controlar diferentes aspectos de su funcionamiento. Las hormonas son principalmente producidas por glándulas endocrinas pero también pueden ser secretadas por células intersticiales y epiteliales.
Las hormonas se dividen cinco clases principales:
a- pequeños neurotransmisores implicados en el funcionamiento del sistema nervioso (gonadotropina, somatostatina)
b- derivados de aminoácidos que también tienen funciones neuromotoras (dopamina, catecolamina)
c- proteínicas asociadas a funciones metabólicas y del desarrollo (insulina)

When does the exponential growth of a population stop?
Answer:
When the population reaches its carrying capacity.
Explanation:
As a population grows, there is more competition for resources which can limit a population. There are also natural disasters that can play a role too such as disease. Another factor that is part of carrying capacity is the size of the habitat. If there is no room, then the population cannot increase.

causing a graded depolarization in the post-synaptic membrane
causing a graded hyperpolarization in the post-synaptic membrane
closing Na+ channels in the post-synaptic membrane
Answer:
a
Explanation:
Neurons secrete chemical molecules that act as messenger and takes part in signalling at the arrival of any chemical or electrical impulse are called a neurotransmitter.
The action potential can be started by:
Option a. Opening K⁺ channels in the postsynaptic membrane.
The action can be explained as:
The presynaptic neurons are the active neurons that transmit the impulse from the synapse with the help of neurotransmitters.The resting neurons or the postsynaptic neurons upon receiving the impulse open the channel gates.The postsynaptic receptors interact with the neurotransmitter that leads to the opening or closing of the ionic channels on the membrane.This leads to depolarization of the membrane causing action potential to occur.Thus potassium channels open.

Do you know the Transcription factor name for lapF and naphthalene dioxygenase?
Answer:
The LapF gene encodes one of the largest proteins from Pseudomonas putida, it is required for the bacterial colonization on the solid surfaces; while naphthalene dioxygenase is an enzyme required for the process of aerobic degradation of naphthalene.
Explanation:
LapF is a gene of Pseudomonas putida that is critical during the process of plant root colonization. Mutations in this gene have shown to reduce the ability to colonize plant tissues. On the other hand, the naphthalene dioxygenase gene is also encoded by the genome of Pseudomonas strains. The naphthalene dioxygenase protein catalyzes the hydroxylation of different substrates, however, this enzyme is widely known for acting during the degradation of naphthalene, an organic chemical compound that is toxic in humans.

Based on your model, do you think frogs reproduce sexually or asexually? What are the benefits and drawbacks to this
form of reproduction?
Answer:
Frogs reproducesexually and when organisisms reproduce sexually there are benefits which include:
produces genetic variation in the offspring.
the species can adapt to new environments due to variation, which gives them a survival advantage.
a disease is less likely to affect all the individuals in a population.
A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species , however, outweighs this disadvantage.
Answer:
Frogs reproduce sexually: they require sperm from a male and an egg from a female to produce offspring. This type of reproduction allows for greater genetic variation. But organisms that sexually reproduce need to reach sexual maturity before they can reproduce. They also use energy to find a mate.
how are the respiratory and circulatory systems connected
Answer:
The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
The respiratory and circulatory systems bring oxygen and nutrients to the cells. The respiratory and circulatory systems work together to maintain homeostasis. The respiratory system moves gases into and out of the blood. The lungs contain the bronchi, bronchioles, and alveoli.

Compare and contrast the reproductive cycles of a flowering plant and a human. Include two similarities and two differences in your answer.
Answer:
Similarities: 1) They both reproduce sexually by fertilization 2) They both have male and female reproductive parts
Differences: 1) Plants can either be monosexual or bisexual while humans are always bisexual
2) Plants employ double-fertilization while humans don't
Explanation:
All organisms including plants and humans have to reproduce in order to produce young generations. However, there are similarities and differences between the reproductive cycles of these organisms. According to the question, we'll be comparing and contrasting reproduction in flowering plants and humans.
SIMILARITIES:
Both flowering plants and humans have sexual means of reproducing, which involves fusion of male and female gametes to produce a ZYGOTE, a process called FERTILIZATION.
Also, the opposite gametes that fuses during fertilization are produced by distinct male and female parts on both flowering plants and humans. For example, the anther produces the pollen containing the male gametes, while the ovary produces the egg cells in flowering plants. The testes and ovary produce the sperm and eggs in humans.
DIFFERENCES:
Flowering plants can either be monosexual i.e. bear both male and female reproductive structures on same plant or bisexual i.e bear the different reproductive structures on different plants. Humans are always bisexual i.e. they bear different reproductive structures depending on the sexuality.
A phenomenon unique to flowering plants called Double Fertilization occurs. This is a process whereby a triploid endosperm is formed from the fusion of two haploid nuclei with a sperm cell. This process only occurs in flowering plants and is absent in human reproductive cycle.

Explanation:
A person in a dark room looking through a window can clearly see a person outside in the day light . But a person outside cannot see the person inside
Explanation:
The explanation for this is that the space outside is illuminated with light from the sun. The person inside has either a lesser or no illumination at all. The dark inside room appears dark, and darkens the surface of the window facing inside, making it act like the silvered surface of a mirror. When the outside observer looks at the window, the window acts as a mirror, reflecting the light from the sun onto the eyes of the outside observer. For the inside observer, some of the illumination from outside finds its way inside, since the outside window surface is well lit, carrying with it the sensation of vision onto the eyes of the inside observer.
The image shows the skulls of three different organisms. The foramen magnum position is the hole in the skull where the spinal nerve cord passes through. Based on the structure of the skulls, which two statements can you infer?
Complete question: The image shows the skulls of three different organisms. The foramen magnum position is the hole in the skull where the spinal nerve cord passes through. Based on the structure of the skulls, which two statements can you infer?
a) All three organisms share a common evolutionary lineage
b) Wolves do not share any common ancestors with humans and chimpanzees.
c) Humans likely share more common ancestors with chimpanzees than they do with wolves.
d) Chimpanzees share more common ancestors with wolves than they do with humans.
Note: The skull figures are shown in the attached file
Answer:
a) All three organisms share a common evolutionary lineage
c) Humans likely share more common ancestors with chimpanzees than they do with wolves.
Explanation:
Although controversial, there is a theory that states that the foramen magnum is associated with bipedalism and human beings´ evolution. According to different studies, the foramen magnum moved from the posterior part of the skull to a central and ventral position. This displacement occurred as mammals began to move in two legs - bipedalism-.
When comparing different mammals skulls it seems evident that bipedalism and foramen magnum position and orientation are highly related. Although all mammals have a common ancestor, the foramen magnum of bipeds mammal organisms is located more anteriorly and ventral than the foramen magnum of the quadrupeds mammals.
In the exposed example, when comparing these three skulls, the two statements that might be inferred are:
a) All three organisms share a common evolutionary lineage. This is true because they are all mammals, and as a group, they share a common ancestor in evolution.
c) Humans likely share more common ancestors with chimpanzees than they do with wolves. This is true because by analyzing the foramen position, we can see that both the chimpanzee and the human´s foramen is located on the ventral side of the skull. Chimpanzees´ hole is more posteriorly and humans´ hole is more anteriorly or centrally located, but in both cases, they are in ventral position. Wolves´ hole, on the other hand, is located posteriorly. As we said before, Although all mammals have a common ancestor, the foramen magnum of bipeds mammal organisms is located more anteriorly and ventral than the foramen magnum of the quadrupeds mammals. And groups closer to human beings (in this case is chimpanzee) show their foramen magnum in a similar place than those mammal groups that are further in evolution (wolves).

Then 1. Explain what Bt corn is and how it is made. 2. Describe the benefits of Bt corn. 3. Describe the risks of Bt corn. 4. Make an argument for or against the use of Bt corn and provide support for your position.
1. Bt maize is a genetically modified maize. It is produced through biochemical techniques and with the use of biotechnology that allows genes of Bacillus thuringiensis bacteria to be introduced in the DNA of corn. These genes allow Bt maize plants to produce a toxic protein specific to certain groups of insects.
2. With the production of this protein, Bt corn becomes immune to attack by these insects. As a result, the use of pesticides in the corn crop is reduced, which makes production healthier and avoids side effects on the soil. In addition, it prevents the production of corn from falling due to the attack of insects.
3. Among the disadvantages, we can say that Bt maize does not control all the pests that attack maize, only a few, which allows maize to be attacked. It can also trigger evolution in pest species that are immune, creating a toxin-resistant species. Finally, it can create contamination in wild maize crops (that is, those that have not been genetically modified), ending diversity.
4. I believe that the use of Bt corn is favorable. This is because it allows a greater production of food to meet our need and increasingly intense demand for food. However, it is necessary to affirm that the use of this corn needs regulation and inspection, mainly in the big industries that can harm the small producer.
