Which postulate of natural selection is deliberately enforced by dog breeders using artificial selection?.

Answers

Answer 1

Dog breeders actively assert that reproduction and survival are not influenced by chance by using artificial selection.

Advantage in reproduction biological selection?

The mechanism of evolution known as reproductive advantage modifies the population's heritable features. Natural selection, according to the theory of evolution, is the process through which a species' phenotype—its outwardly manifested genetic traits—can change over time.

Why is reproductive success critical to the process of natural selection?

Long life is not favored by natural selection unless it allows for or resulting in increased reproductive success. Similar to this, even though we might wish it were the case, there isn't necessarily a premium placed on intelligence, physical prowess, or beauty unless these qualities actually result into more offspring than normal.

What is central nervous system?

The brain and spinal cord make up the central nervous system.The brain directs our thoughts, memories, movements, and emotions.Between the brain and the nerves that travel throughout the body, the spinal cord relays signals.Both the brain and the spinal cord are encased in bone, the vertebrae, a group of ring-shaped bones, protecting the spinal cord and the brain respectively. Both of them are supported by cerebrospinal fluid and meningeal membrane layers. The fluid circulates along the spinal column and via ventricles, or hollow chambers, in the brain. It nourishes, feeds, and removes waste from the central nervous system.

Parts of the brain:

The brain is both very intricate and little. The average adult brain barely weighs roughly 3 pounds. It contains several folds and grooves where significant information is kept. The cerebrum, brainstem, and cerebellum are the three major components of the brain.

As information is processed, each lobe handles a certain type:

Complex thought processes including planning, picturing, coming to conclusions, and reasoning take place in the frontal lobe. Back of the forehead is where it is.The parietal lobe handles information regarding temperature, taste, and touch.

which of the following mechanisms can cause two different proteins to be produced from the same gene?

Answers

The mechanisms which can cause two different proteins to be produced from the same gene is b)mRNA splicing. So, correct option is b.

mRNA splicing is defined as a process in molecular biology where a newly-made precursor messenger RNA (pre-mRNA) works as a transcript and transformed into a mature messenger RNA (mRNA). It actually works by removing all of the introns (non-coding regions of RNA) and splicing back together the exons (coding regions).

For nuclear-encoded genes, splicing occurs in the nucleus either during or immediately after transcription. For eukaryotic genes that contain introns in them , splicing is usually needed to create an mRNA molecule that can be translated into protein.

For eukaryotic introns, splicing occurs as the series of reactions which are catalyzed by the spliceosome, a complex reaction of small nuclear ribonucleoproteins (snRNPs).

imagine all the histone h3 molecules in the cell have a mutation that changes their lysine-9 residue to an alanine. assuming this cell could still live, what would be the result?

Answers

In Drosophila, the dSAGA complex containing dADA2b is involved in the acetylation of histone H3, lysines 9 and 14. Curiously, dAda2b mutants have greatly reduced lysine 9- and 14-acetylated histone H3 levels, but these animals survive to late development.

To investigate the molecular effects of loss of histone H3, lysine 9 and 14 acetylation, we compared the global messenger ribonucleic acid (mRNA) profiles of wild-type and dAda2b mutant animals at two developmental stages. Global gene expression profiles show that dSAGA-specific loss of H3-lysine 9 and 14 acetylation results in expression changes (up- or down-regulation) of rather small gene subsets and does not cause global transcriptional deregulation. I'm here. Among the genes upregulated in dAda2b mutants are those that play a role in antimicrobial defense mechanisms. Results from chromatin immunoprecipitation experiments show that in dAda2b mutants, lysine-9-acetylated histone H3 levels are reduced in both up- and down-regulated genes of dSAGA. In contrast, the promoter of the dSAGA-independent ribosomal protein gene of the dAda2b mutant maintains high levels of histone H3K9ac. Our data suggest that dSAGA differentially alters Pol II accessibility to specific promoters by acetylating H3 at lysine 9.

Shay creates a wave that has a frequency of 20 waves every ten seconds. How does the energy that her wave carries compare to a wave that has a frequency of 5 waves every ten seconds? Justify your response.

Answers

A frequency which produce 20 waves every ten seconds has more frequency and less wavelength than that which produces 5 waves every ten seconds.

What is Frequency?

Frequency is the number of waves that pass through a fixed place in a given period of time. So, if the time taken for a wave to pass is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency will be 100 per hour.

The frequency of 20 waves every ten seconds can be simplified as 2 waves produced per second.

The frequency of 5 waves produced every ten seconds can be simplified as 1 wave produced every two seconds or 1/2 wave produced every second.

Therefore, the frequency of first wave is more than the second wave and the wavelength of first wave is less than the second wave as wavelength is inversely proportional to the frequency of wave.

Why does it make sense that acetyl-coa stimulates the activity of pyuruvate carboxylase?.

Answers

Acetyl-CoA indicates that the conversion of fat to carbs is necessary. Acetyl-CoA carboxylase accumulation indicates a lack of citrate. NADH is produced for energy when pyruvate carboxylase is activated by acetyl-CoA.

Why is it logical that acetyl-CoA would cause pyruvate carboxylase to be activated?

Acetyl-CoA selectively activates pyruvate carboxylase. When acetyl-CoA concentrations are high, organisms use pyruvate carboxylase to divert pyruvate from the TCA cycle because acetyl-CoA is a crucial metabolite in the TCA cycle that generates a lot of energy.

How does pyruvate carboxylase become activated by acetyl-CoA?

The production of more oxaloacetate is triggered by an excess of mitochondrial acetyl-CoA. When lipolysis is induced, for instance, intramitochondrial acetyl-CoA levels rise, allosterically activating pyruvate carboxylase to produce more oxaloacetate for gluconeogenesis.

False: Angiotensin II is a substance made by the body to lower blood pressure during stress. group of answer choices

Your body produces a substance called angiotensin that makes your blood arteries smaller. Your blood pressure may rise as a result of this narrowing, which also makes your heart work harder. In order to lower your blood pressure and facilitate your heart's ability to pump blood, angiotensin II receptor blockers work to relax your veins and arteries. Angiotensin II receptor blockers stop the action of angiotensin II. As a result, the medication enables the widening of your arteries and veins (dilate).

Scientists have been measuring increasing levels of greenhouse gases in earth's atmosphere. How do the increasing levels affect ecosystems?.

Answers

An increase in the atmospheric concentrations of greenhouse gases produces a positive climate forcing, or warming effect.

When energy from a planet's host star passes through its atmosphere and heats the planet's surface, greenhouse gases in the atmosphere prevent some of the heat from returning directly to space, resulting in a warmer planet.

The greenhouse effect occurs when some of the Sun's infrared radiation passes through the atmosphere, but the vast majority is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds. This has the effect of warming the Earth's surface and lower atmosphere.

Greenhouse gases have serious environmental and health consequences. They contribute to climate change by trapping heat, which affects a variety of species in already arid environments. Extreme weather, wildfires, droughts, and food supply disruptions are all exacerbated by climate change caused by greenhouse gas emissions.
