Answer:
D. Overcast skies with strong winds.
Explanation:
clouds, high winds, and precipitation occurs if there is low air pressure is present. A low air pressure areas or regions is also known as cyclogenesis because when the intensity of low air pressure occurs, there is high chances of formation of storms or hurricanes in that region. A low air pressure system refers to a large mass of air that rises due to warmer land or water.
In a population of white (W) and black (w) sheep, 22 out of 244 sheep are black. What is the frequency of the dominant allele in the population?
Answer and Explanation:
To calculate the allele frequency in the population, we divide the number of occurrences of the particular allele by total number of all alleles in the population Allele frequencies can be represented as a decimal, a percentage, or a fraction.
Given the population of white (W) and black (w) sheep, 22 out of 244 sheep are black, the frequency of the dominant allele in the population = 222/244×100=

The routes nerve impulses from our senses.
A. thalamus
B. hippocampus
C. brain stem
D. corpus callosum
Answer:
a
Explanation:
The correct answer is C. Brain Stem.
How does the brain stem function?The thalamus and other areas of the brain receive nerve signals from our senses through the brain stem. It is made up of the medulla, pons, and midbrain and is situated at the base of the brain.
The brain stem is in charge of regulating life-sustaining processes including breathing, heart rate, and blood pressure. It is also in charge of transmitting sensory data from the body to the thalamus, which subsequently transmits the data to the relevant parts of the brain.
Although the brain stem is the main pathway for nerve impulses from our senses, the hippocampus, corpus callosum, and thalamus are all important in the processing of sensory information.

The amount of fog during different times of the year b. The composition and amount of seasonable melt water c. The daily production of sulfur dioxide by a nearby factory d. The heaviest traffic periods of the year
The independent variable is the scientists most likely monitoring in their investigation for the investigate the effects of chronic acidification on a desert ecosystem - c. The daily production of sulfur dioxide by a nearby factory
Chronic acidificationEcosystems result in chemical changes to soil and to surface waters and groundwater as a result of reduction of base cation or H⁺. The major effects of SO2 emission have on the soil system
An increase in contents of total sulfur, organic carbon, and exchangeable Al, leads to a lowering of pH and causes acidification of soil. Fog does not participate in acidification

Arrange the following concepts from simplest to most complex: Chromosomes, DNA, Genome, Gene
Answer:
DNA -> Gene -> Chromosome -> Genome
Explanation:
A genome is an organism's complete set of DNA including all of its genes. Each genome contains all of the information needed to build and maintain that organism. Chromosomes are the threadlike structures located inside the nucleus of animal and plant cells. A gene is the basic physical and functional unit of heredity.
The material and components that are vital for the growth and functioning of an organism that gets inherited from parent to offspring are the components of genetic information.
From simplest to complex they are arranged as:
DNA ⇒ Gene ⇒ Chromosome ⇒ Genome
DNA is the deoxyribose nucleic acid and is the genetic material that transports the instruction for development and function for growth. Gene is a unit of hereditary that codes for gene products.DNA molecules packed as a thread-like structure is called chromosomes.The entire set of genes that pass from parent to offspring is called the genome.To learn more about genome and genes follow the link:

A. Describe the role of the promoter in eukaryotic gene expression. Explain how a negative regulatory molecule could inhibit transcription at the promoter.
B. Identify TWO events that occur during RNA processing. Explain how RNA splicing increases the variation of mRNA molecules.
C. Describe the role of miRNA in gene expression.
Answer:
Explanation:
A. The role of promoter in eukariotic gene expression is It is to bind transcription factors that regulate transcription initiation. This molecule is so important because control the binding of RNA polymerase to DNA. The promoter region may be short or very long; the longer the promoter is, the more protein binding space is available. A negative regulatory molecule has the possibilty to inhibit transcription at the promoter because these molecule block the binding of RNA polymerase to the promoter region, thus not allowing the initiation of transcription, in some particular cases the negative regulator binds to the lac repressor and will bind to the promoter in the same site where RNA polymerase would bind to.
B. Two process that occurs during RNA processing are RNA splicing and 5′ capping, 3′. RNA splicing is a process known for removing the introns from the pre-RNA and stuck back together the restant parts, exons. This process has as a goal form a mature mRNA that does not contain the intron sequences. RNA splicing has an effect on the variation of mRNA molecules because through a process called alternative splicing more than one mRNA can be made from the same gene.
C. Even though they are not quite the same thing miRNA and negative regulatory molecules have the same role, which inhibits the translation and silence genes. They regulate gene expression by binding to the 3'-UTR of their target mRNAs and destabilizing the mRNA and translational silencing, repressing protein production. Even so, under specific circumstances, miRNA can activate translation or regulate transcription.

What happens to the effenciency of the exchange of oxygen in the human body at a high altitude
Answer:
The effiency decreases at higher altitudes
Explanation:
The higher up a person is on a mountain, the thinner the air is due to the lack of plants that can grow. An example of this is Mount Everest. At a certian point on the mountain, called the "Death Zone", the air is too thin to supply enough oxygen to the human body to survive. That's why they bring oxygen tanks with them on their adventures.

On which side of the mountain would you be most likely to find a forest?
Answer:
Mountain lands provide a scattered but diverse array of habitats in which a large range of plants and animals can be found. At higher altitudes harsh environmental conditions generally prevail, and a treeless alpine vegetation, upon which the present account is focused, is supported. Lower slopes commonly are covered by montane forests. At even lower levels mountain lands grade into other types of landform and vegetation—e.g., tropical or temperate forest, savanna, scrubland, desert, or tundra.
The largest and highest area of mountain lands occurs in the Himalaya-Tibet region; the longest nearly continuous mountain range is that along the west coast of the Americas from Alaska in the north to Chile in the south. Other particularly significant areas of mountain lands include those in Europe (Alps, Pyrenees), Asia (Caucasus, Urals), New Guinea, New Zealand, and East Africa. The worldwide distribution of mountain lands is shown in Figure 1.

Suggest a way that each farm could change their farming practices to prevent pollution of the river with nitrates. Gizmo
Answer:
An improved agricultural practices such as adjustment of application rate, application of the right amount of nitrogen, use of slow controlled release fertiliser, applying nitrogen fertilisers when least susceptible to loss, crop rotation
Explanation:
The various ways are available to reduce or prevent pollution of the river with nitrates, the most effective is:- reducing or not use of artificial or industrial-based nitrogen fertilizers and using biofertilizers.
Agriculture or farming contributes to water pollution when using fertilizers more than the required amount or easily lost fertilizers. This increases the of nutrients including nitrates in the river that cause the growth of algal bloom and eutrophication.
There are several ways to control the nitrates in the river:
