Answers
Answer:
The correct answer is - provides cushioning for the brain.
Explanation:
The cerebrospinal fluid or CSF is a clear colorless fluid that is present within the tissue that surrounds the spinal cord and the brain of all vertebrates. The major and main role or function of CSF is to provide a cushion to the brain within the skull and acts as a shock absorber from the outer world impact for the central nervous system.
Other than providing a cushion for the most sensitive body part brain, CSF also transports nutrients and chemicals filtered from the blood and removes waste products from the brain.

Answers
Answer:
músculo cardíaco
Explanation:
Los 3 tipos de tejido muscular son 1-músculo cardíaco o miocardio (involuntario), 2-músculo liso (involuntario) y 3-músculo esquelético (voluntario). Las células del músculo cardíaco, las cuales son conocidas como 'miocardiocitos', poseen una apariencia estriada y forman la pared del corazón. Los miocardiocitos son alargados, ramificados, y poseen un núcleo central (son células uninucleadas, a diferencia de las células del músculo esquelético, las cuales son multinucleadas). Además, los micardicitos son más cortos (80 a 100 µm) y más anchos (aprox. 15 µm) que las células del músculo esquelético. Los miocardiocitos presentan uniones especializadas conocidas como discos intercalares, los cuales son un tipo de complejo de unión entre los límites de dos cardiomiocitos. En el citoplasma de los cardiomiocitos se encuentran las miofibrillas, las cuales son estructuras contráctililes que les confieren a las células musculares sus propiedades características de contracción y de elasticidad. En estas células (cardiomiocitos) las miofibrillas se disponen de manera longitudininal con un patrón estriado.

An individual with two different versions of a gene is genetically ____________ . In traits with a simple pattern of inheritance, only the trait conferred by the ____________ form of the gene will be visible. The other form of the gene is ____________ : it confers a trait that is only visible when the individual is genetically ____________ , or has two identical copies of the gene.
Answers
Answer:
heterozygous; dominant; recessive; h.o.mo-zygous
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
In Genetics, co-dominance can be defined as a phenomenon in which two (2) alleles of the same gene are present in a living organism and both are equally expressed to a degree or simultaneously.
This ultimately implies that, co-dominance is a phenomenon that typically involves the relationship between alleles i.e the two (2) versions of a gene present in living organisms. Also, a single version of a gene expressed by a living organism is referred to as an allele.
Trait can be defined as a distinguishing quality or characteristic of a living thing.
Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.
Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.
In Genetics, when an individual has two (2) different versions of a gene, he or she is said to be genetically heterozygous.
In traits with a simple pattern of inheritance, only the trait conferred by the dominant form of the gene from the parent organism will be visible in the offspring of a living organism. The other form of the gene is recessive : it confers a trait that is only visible when the individual is genetically , or has two identical copies of the gene.

B. Random mating occurs within the

quency
C. An allele becomes more common in a
population.
Answers
Answer:
C
Explanation:
Natural Selection can cause micro evolution, or a change in allele frequency over time
An allele becomes more common in a population. So, the correct option is (C).
What is an Allele Frequency?Allele frequency is also known as gene frequency. It is defined as the relative frequency of an allele at a particular locus in a population, expressed as a fraction or percentage. It is the fraction of all chromosomes in the population that carry that allele over the total population or sample size.
It forms the basis of many population and medical genetic studies. Many evolutionary forces change allele frequencies where allele frequencies can be used to trace past evolutionary events.
Allele Frequency is expressed as:
[tex]1 = p^2 + 2pq + q^2[/tex]
p and q each represent the allele frequency of different alleles.
Thus, an allele becomes more common in a population. So, the correct option is (C).

What is a truck's acceleration if the net external force on the truck is 560 N and it has a total of mass of 1000 kg?
Answers
Answer:
0.56m/s²
Explanation:
The above is the correct answer.
Force = mass x acceleration = mg
⇒ F = mg
where F = 560 N, m = 1000kg
∴ g = F/m = 560/1000 = 0.56
∴ acceleration, g = 0.56m/s² (answer)
Force is known to be a push or a pull which actually puts a body to motion or brings a body to rest. It has to do with the interaction between bodies.
Match the surface to its respective albedo score. fresh snow soil ocean (high-angle sun) ocean (low-angle sun) 0.95 arrowRight 0.2 arrowRight 0.9 arrowRight 0.05 arrowRight Reset Next
Answers
Answer:
fresh snow → 0.9soil → 0.2ocean (high-angle sun) → 0.05ocean (low-angle sun → 0.95Explanation:
Albedo is the radiation reflected by the earth´s surface to the universe.
Albedo might be defined as a relation between reflected light from a particle and the incident light. It is the fraction of the incident radiation that is reflected by any object. If the surface is mostly clear and clean, most of the incident radiation is reflected. But if the surface is dark and rugose, most of the incident radiation is absorbed, and the temperature of the absorbing object will increase.
Albedo value is always inferior or equal to one and can be expressed as a percentage. The surface that reflects 100% of the incident light will have an albedo value = 1. But if the surface absorbs all the radiation and does not reflect any percentage, the albedo value = 0. Note: there is no real object that might reflect or absorb 100% of the incident radiation.
The importance of albedo is that it avoids high temperatures on the earth. There are many different surfaces with different albedo values. Global variations in albedo are natural processes due to exogenic and endogenic variations. But to these natural events, we must add all the variations caused by human beings´ actions, which increase greenhouse gases, decreasing albedo, and increasing global warming. The increase of greenhouse gases, such as CO₂, decreases albedo. The same occurs with atmospheric dust due to volcanic eruptions. Additional material interposes between the earth´s surface and the universe, decreasing the energy return to the universe.

Surtsey is a volcanic island that was formed off the coast of iceland in the 1960s. After the eruption that created the island, organisms slowly arrived and grew on the island. The first organisms were some bacteria and fungi. Within about two years, the first vascular plants had arrived and by the end of the first decade there were 10 species of vascular plants on the island. Forty years later, there were about 60 species of vascular plants. What is likely true about this situation
Answers
Answer:
The first organisms were some bacteria and fungi.
Explanation:
The first organisms were some bacteria and fungi on the Island of Surtsey because these bacteria and fungi are present in the surrounding air which can easily reach to that Island. The bacteria and fungi make the environment favourable for the growth of plants and animals. These bacteria and fungi ready the ground for the plants so that they can grow easily with the passage of time.
Surtsey an volcanic islandic island lies in V. archipelago that is the southern coast of island. It was created by a volcanic eruption at 130 meters below sea level.
After the eruption of the volcano on the island, some vascular plants have been found to grow on the northern shores. Mosses were found in 1967. and the lichens were the first to be found. Now the island is covered by the presence of mosses and lichens. This shows within about two years, the first vascular plants had arrived and by the end of the first decade, there were 10 species of vascular plants on the island.Learn more about the volcanic island that was formed off the coast.
