An independent variable is that which one can change at will, considering the different purposes of a particular research or experiment. In this case, then, the independent variable would be the colors of the light, and the dependent variables would be those related to plant growth, and moisture, since are factors that are regulated by the intensity or the color of the light (we have to know that different colors of light will have different wavelengths, in hence, different temperatures).

The refractory period is the time in which the cell membrane remains depolarized, that is, it does not react to a second stimulus. It takes place after an excitation of the cell.

Ecology: Ecological succession, ecosystem

The stability of an ecosystem refers to the ability of an ecosystem to return to equilibrium after a perturbation such as a wildfire, for example, the ecosystem was a forest before the wildfire, and then it can return to being a forest after the fire.

If a severe wildfire wipes out all plant and animal life, then the biotic elements of that ecosystem are destroyed, and a secondary succession begins to take place. This not necessarily means that the same species would colonize.

We are between two options that correctly identify the plants and animals as biotic factors:

B. Plants and animals were destroyed by the wildfire, and even if the abiotic factors remain the same, the ecosystem can never return to stability.

D. Plants and animals were destroyed by the wildfire, but if abiotic factors remain the same, the ecosystem can return to stability.

The first colonizers in a secondary succesion are plants such as grass and herbaceous plants, and the kind of plants that can grow in a place depends on the soil characteristics, sunlight, and water supply, i. e. abiotic factors. So, if the abiotic factors remain the same, the ecosystem should be able to return to stability.

This means the right answer would be D. Plants and animals were destroyed by the wildfire, but if abiotic factors remain the same, the ecosystem can return to stability.

STEPS IN THE FORMATION OF SEDIMENTARY ROCK

Sedimentation starts when rocks get weathered by rains and winds. The eroded sediments will be washed o scarried in the water. Over time, more sediments will pile up in the water and compresses the lower layers. Strata of layers will happen as time passes by. The salt and dissolved ions in the water act as glue to make it into a rock mass. The rock mass formed is now what we call a sedimentary rock. n

The correct option is B. Law of segregation.

In the list of evolutionary events, we can see that their logical sequence is:

0. First prokaryotic cells evolved

1. Photosynthetic prokaryotes evolved, producing O2

2. First eukaryotic cells evolved

3. First multicellular life evolved

This means the options are in chronological order and we only need to order the age from oldest to the most recent one:

0. 3.5 billion years

1. 2.8 billion years

2. 2.1 billion years

3. 650 million years

Human activities

Human activities are one of the main causes of deforestation. Among them we can find the expansion of urban areas, in which natural areas are deforested to build houses or factories for example; we can also list the expansion of agricultural areas, in this case, several hectares of forests are cut down to be replaced with the cultivation of plants for human consumption and finally another huge problem is the illegal logging of trees, which even occurs in protected natural areas.

Natural causes

Among the natural causes, we can find forest fires, which although sometimes are caused by humans, can also occur in times of extreme heat such as the canicular period; we can also list the presence of pests, which infect and kill the trees reducing their population and finally, another natural cause related to the weather could be that a period of drought occurs.

Blue-green algae is an  important organisms that play different roles in the nitrogen cycle.

Blue-green algae converts nitrogen into organic nitrogen compounds as well as Nitrobacters and other Nitrogen-fixing microbes. They are essential to healthy water bodies as they are responsible for producing oxygen and are a source of food to certain aquatic animals.

Nitrates and ammonia produced in the nitrogen cycle are as a result of nitrogen fixation made by algae and plants that animals eats and incoporate into their body compounds. They are able to convert dinitrogen however unavailable into bioavailable ammonia.

Specific molecules found in one cell have a regulatory function, those regulatory molecules can be activator proteins that bind to the regulatory sites of the DNA acting as a on/off switches in the process of transcription, since the RNA that will be formed can be translated into different amino acid sequences. The CRISPR-Cas9 system is a example of gene expression supressor and activator used in molecular biology as a gene edit tool. The process of gene activation start when a transcription factor (protein) bind to bits of the DNA (that are marked by a promoter), the sequence marked is transcribed into a molecule of mRNA, this RNA will be translated in the cytoplasm into a animo acid sequence that will form a protein, being that protein from the gene "selected" and "marked" by the transcription factors. Each cells have they transcription factors, and the moment that they are triggered to work by an intracellular or extracellular stimulus.

The best option is Hemoglobin is composed of four globin molecules, each with their own heme group that binds to and carries oxygen.

Hemoglobin has a quaternary structure it carries oxygen in red blood cells.

The structure of a typical neuron has a Myelin sheath (myelin is produced by the Schwan cell, in the peripheral nervous system), in the axon area, also certain points called along the axon are called nodes of Ranvier, these are, small unmyelinated areas. When action potentials occur in a neuron, only happen in the nodes of Ranvier (unmyelinated areas). This exact mechanism, saltatory conduction, is made possible by the presence of myelinated areas what makes that the action potential propagates faster than it would in a un unmyelinated axon.

Color code: Yellow are the myelinated areas, and the orange dots between them are the nodes of Ranvier

This is an example of incomplete dominant trait, in which any of the alleles complete expresses over the other, giving a resulting phenotype for the heterozygous genotype that is intermediate between the homozygous genotype.

The correct option is b. incomplete dominant.

United states is the second country with the most CO2 emissions, which is a greenhouse gas. Most of the CO2 comes from the energy sector,

According to the graph, the two factors that characterize biomes are precipitations and temperature.

The process that can only be carried out byplants in the presence of light-dependent reactions. These reactions convert light energy to chemical energy and is present in the process of photosynthesis. The energy from the sun together with water is being broken down to give rise to ATP and NADPH which are used in light-independent reaction or dark reactions.

Cellular respiration does not use light since it is not dependent on light. Dark reactions are light-independent processes. Homeostasis is the maintenance of the internal environmentr of an organism in order to survive.

Answer - B light-dependent reactions

Answer: B. light-dependent reactions

The disorders that has been commonly known are Down syndrome, Turner syndrome and Klinfelter syndrome.

Down syndrome, Turner syndrome and Klinefelter syndrome are the genetic disorders which has been found in the chromosomes. Down syndrome has a common genetic disorder that occurs when the  person has three copies of 21st chromosome. It is also called  trisomy 21. Due to this disorder, delays occur in physical and mental developmental and disabilities of human body parts.

In Edward's syndrome, there is an extra copy of the chromosome 18. In Down's syndrome, there is an extra copy of chromosome 21 and in the Klinefelter's syndrome, there is an extra copy of X chromosome.

The back portion of the brain that controls vision is called the occipital lobe.

What is the occipital lobe?

One of the four main lobes of the cerebral cortex of the mammalian brain is the occipital lobe. The name is a result of where it is located on the back of the head. The majority of the physical region of the visual cortex is located in the occipital lobe, which is the mammalian brain's visual processing hub. Of the four paired lobes in the human brain, the two occipital lobes are the tiniest. The posterior cerebrum includes the occipital lobes, which are situated in the back of the skull. The lobes of the brain are named from the overlying bone and the occipital bone overlies the occipital lobes.

Hence, the answer is the occipital lobe.

Answer the animal dies

Explanation:

Answer: The animals die I hope this is helpful please mark me brainlist if correct then no if wrong

Explanation:

The animals die and the chemical goes into the soil for the plants and when the animals eat the plants the chemicals are passed back to the plants.Prairie plants are especially adept at storing carbon, locking up large amounts in their roots. In fact, prairies store more carbon below ground than a forest stores above! Deep, complex prairie root systems sequester (store) carbon and – with the help of microorganisms – move it to the soil where it stabilizes.

The T. Rex lived at the end of the Cretaceous period (67 million years ago approximately), before the cretaceous-tertiary massive extinction.

By definition, features that are shared due to a common ancestor are homologous structures.

Now, notice that all mammals share the homologous structure of the vertebrae in common.

As we can see, throughout the experiment, most of the variables, such as sunlight, size or temperature remained constant with NaHCO3 concentration being the only variable that changed.

NaHCO3 provides CO2 in the aquatic environment and therefore stimulates photosynthesis by increasing the average oxygen obtained in the 5 tests.

However, photosynthesis is no longer stimulated after reaching a concentration of 80 g/L NaHCO3.

Therefore, we can expect that at higher concentrations (120, 140, etc.) there is no significant change and therefore, the optimum NaHCO3 concentration would be 80 g/L NaHCO3.
