The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. This is because molecules can only complete the reaction once they have reached the top of the activation energy barrier.

Macrophage cell types secrete significant amounts of pro-inflammatory cytokines in response to Covid-19 infection. Here option D is the correct answer.

Macrophages are a type of white blood cell that plays a crucial role in the innate immune response to viral infections, including COVID-19. In response to viral infection, macrophages can secrete a wide range of pro-inflammatory cytokines, such as interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α).

These cytokines are important for activating and recruiting other immune cells to the site of infection, and for initiating an effective immune response to clear the virus. However, in some cases, the immune response to COVID-19 can become dysregulated, leading to excessive production of pro-inflammatory cytokines, known as a cytokine storm.

This can cause damage to the lungs and other organs and is associated with severe disease and poor outcomes in COVID-19 patients. Macrophages are thought to be a key contributor to the cytokine storm in COVID-19, highlighting the importance of understanding the immune response to the virus in order to develop effective treatments and prevent severe disease.

Answer:

Tectonic plate motion caused the Atlantic Ocean basin to increase in size.

Explanation:

Tectonic plate motion caused the Atlantic Ocean basin to increase in size. In fact, all of the differences in size, shape, and position seen between the two maps are due to the shifting of tectonic plates over time.

According to plate tectonic theory, tectonic plate motion caused the Atlantic Ocean basin to increase in size. Therefore, option A is correct.

Huge fragments of the Earth's crust and upper mantle make up tectonic plates. They are composed of both continental and oceanic crusts. Around mid-ocean ridges and the significant faults that define the plate boundaries, earthquakes happen. African, Antarctic, Eurasian, Indo-Australian, North American, Pacific, and South American are the seven primary plates mentioned in the World Atlas.

Large rock slabs called tectonic plates, which separate the Earth's crust, are continually moving and changing the planet's topography. According to the framework of ideas underlying the plate tectonics theory, the lithosphere, the Earth's outer shell, is divided into many plates that move across the rocky interior of the planet.

Tectonic plate motion caused the Atlantic Ocean basin to increase in size. Thus, option A is correct.

When a piece of chromosome breaks off and reattaches at another site on the same or another chromosome, this is called chromosomal translocation.

In the field of science, chromosomal translocation can be described as a process in which a region of genes that is present on one chromosome have the ability to break and jump from to another chromosome and join to the other chromosomes.

These genes that take part in the process of chromosomal translocation are referred to as the jumping genes. It is due to the phenomenon of chromosomal translocation that same regions of genes in one chromosome can be found in another chromosome as well.

The given statement is false that in gene expression in eukaryotes, the primary transcript is transported unchanged directly to the cytoplasm and is ready for translation.

Primary transcript of DNA is called the pre m-RNA. It can be considered as the raw m-RNA that undergoes various types of processing in the nucleus itself before it is transported and translated. The processing that the pre m-RNA undergoes is capping, splicing and tailing.

Translation is the process of conversion of m-RNA into proteins. This occurs in the ribosomes at the cytoplasm. Translation requires the role of r-RNA and t-RNA as well for the protein to be formed.

When a roan cow (RW) and a pure red cow (RR) are mated, the phenotype ratio of the offspring is 1:1.

The phenotype ratio of offspring will be 1:1, meaning that half of the offspring will be pure red (RR genotype) and half will be roan (RW genotype). The red cow can only contribute a "R" allele to the offspring, while the roan cow can contribute either a "R" or "W" allele. Therefore, each offspring has a 50% chance of inheriting a "R" allele from the red cow and a 50% chance of inheriting a "R" or "W" allele from the roan cow, resulting in a 1:1 ratio of pure red to roan offspring.

Natural experiments are observational studies in which participants are randomly assigned to groups that allow the researcher to draw causal relationships between an event and a factor. These experiments are used in studies where it would be unethical and unacceptable to subject human participants to such conditions. It is most times applied in epidemiological studies.

Since the researcher cannot control an earthquake which is a natural occurrence, this can be rightly described as a natural experiment. Controls are not used in this type of experiment.

The sentence that supports the statement that hormones are involved in the regulation of homeostasis is: The hormone erythropoietin increases the production of red blood cells when oxygen levels are low.​

Homeostasis is the condition of maintaining the adequate conditions inside the living body that are most suitable for its survival. It is the state of steady internal, physical, and chemical conditions. The correct temperature, adequate oxygen concentrations, adequate fluids inside the body are the examples of homeostasis.

Erythropoietin is the hormone produced by the kidney cells that enhances the production of RBCs in the body. This in turn enhances the oxygen concentration inside the body.

Answer:

The main difference between the scientific method and the CER is the number of steps recommended by each one to make a valid scientific observation.

Explanation:

The scientific method consists of a set of steps that aims to establish a scientific experiment capable of explaining a scientific phenomenon hitherto unknown, or little explained. The scientific method consists of many stages, where each completes the other.

The CER method, on the other hand, has only three stages, which are claim, evidence, reasoning. This method can be established and finalized more quickly than the scientific method and is not as judicious, but it also presents efficient results to justify or explain a scientific phenomenon.
