Answer:

The energy necessary to contract our muscles and therefore to start jogging comes from adenosine triphosphate (ATP). When ATP is broken down into ADP (adenosine diphosphate) and Pi (phosphate) energy is released, and this is the energy used to contract the muscles.

Explanation:

Jogging is a form of running that involves jogging or running at a slow or leisurely pace (moderate speed) outdoors. Instructions for jogging are provided by the central pattern generators, located just below the brain. Muscle fibers are the cells that make up muscles and have the ability to contract and relax in response to messages from our central nervous system. Basically, to function the muscles need ATP (Adenosine Triphosphate) and they obtain it through 3 energy systems: The phosphagen system allows to obtain energy quickly for explosive movements, where there is no time to convert other fuels into ATP; the glycolytic system (or anaerobic lactic), the muscles (and liver) in addition to ATP, store glycogen, that glycogen is converted to glucose and then ATP, allowing intense activity (although less than in the previous case) for a few minutes And lastly, the oxidative system (or aerobic) is probably the most widely used by long-distance runners, it is the slowest way to obtain ATP, but it can generate energy for hours. This system needs oxygen to generate ATP.  All three may be contributing energy simultaneously, but there will always be one that prevails over the others at any given time.  Glycogen is vital for joggers, so they must take care and analyze their diet to obtain the correct source of energy that their muscles require.

Answer:

this is true it neutralise easily

It is true that in the DNA isolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.

DNA extraction is a method of separating DNA from cell membranes, proteins, and other cellular components using physical and/or chemical methods from a sample. In 1869, Friedrich Miescher isolated DNA for the first time.

The ability to extract DNA is critical for studying the genetic causes of disease and developing diagnostics and drugs.

It is also required for forensic science, genome sequencing, detecting bacteria and viruses in the environment, and determining paternity.

Because sodium (Na+) neutralizes the negative charge of DNA, cells are mixed with sodium chloride (i.e. NaCl) during the DNA isolation process. It makes homogenization easier.

Thus, the given statement is true.

A heterotrophic and chlorophyll protist

Food is ingested by protists in three forms. We produce, eat and digest their own organic molecules. Meat ingestion or english bacteria ingests protists. The cell wall and cell membrane are stretched to create an alimentary vacuolum around the foodstuff. Enzymes extract the food inside the food vacuole. At the other side, absorbent protists consume food molecules through their cell membrane by diffusion. In decomposition, absorbent protists play a crucial role. They are assumed to be essential decomponents. Light energy is used to make your own food by big farmers including photosynthetic protists.

False: The pancreatic and spleen's secretions also reach the small intestine and are crucial to the process of chemical digestion.

What is intestine ?

From the stomach to the anus, the intestines form a long, continuous tube. Intestinal fluid is where most water and nutrients are absorbed. Small, big, and the rectum are all parts of the intestines.

About 20 feet long and an inch wide, the small intestine (small gut) is a tube. Its responsibility is to ingest and absorb the majority of the nutrients. The small intestine is made up of three sections: the duodenum, jejunum, and ileum, and is lined by velvety tissue.

About 3 inches wide and 5 feet long, the large intestine (also known as the colon or large gut) is a tube. Stool is produced as a result of the colon absorbing water from waste. The urge to urinate is triggered by the rectum's nerves as stool enters.

Answer:

Part A:

Frequency of bb genotype=0.2111

Part B:

Frequency of B alleles is denoted by x=0.5407

Frequency of b alleles is denoted by y=0.4593

Part C:

Frequency of BB genotype=0.2924

Frequency of bb genotype=0.2111

Frequency of Bb genotype=0.4966

Explanation:

Given:

Total Sheep= 4500

White Sheep=950

B for black allele

b for white allele

Part A:

\(Frequency\ of\ white\ sheep=\frac{White\ Sheep}{Total\ Sheep}\)

\(Frequency\ of\ white\ sheep=\frac{950}{4500}\\Frequency\ of\ white\ sheep=0.211\)

Frequency of white sheep= Frequency of bb genotype=0.2111

Further:

Let frequency of b alleles is denoted by y.

\(Frequency\ of\ white\ sheep=y^{2}= 0.211\\y=\sqrt{0.211}\\y=0.4593\)

Frequency of b alleles is 0.4593.

Part B:

Sum of the frequencies of B and b alleles is 1

Let frequency of B alleles is denoted by x

Let frequency of b alleles is denoted by y

x+y=1

y is calculated in part A and has value=0.4593

x+0.4593=1

x=1-0.4593

x=0.5407

Frequency of B alleles is denoted by x=0.5407.

Frequency of b alleles is denoted by y=0.4593.

Part C:

Three genotypes are BB, Bb, bb

In case of three genotypes frequency is:

\(F=x^2+2xy+y^2\)

Now \(x^2\\\) is for BB genotypes

From Part B;

x=0.5407

\(x^2=(0.5407)^2\\x^2=0.2924\)(Frequency of BB genotype)

Now \(y^2\\\) is for bb genotypes

From Part A:

y=0.4593

\(y^2=(0.4593)^2\\y^2=0.211\)  (Frequency of bb genotype)

From above frequency Formula:

Now \(2xy\) is for Bb genotype:

2*x*y=2*0.5407*0.4593

2*x*y=2*0.2483=0.4966 (Frequency of Bb genotype)

A severe drought in the Georgia marshland ecosystem would have a significant impact. It would lead to reduced water availability, affecting the marsh plants, invertebrates, fish, and bird populations, disrupting the food web and potentially causing population declines and habitat loss.

One of the primary effects of a drought is the reduction in water availability. The marshland ecosystem relies on a delicate balance of saltwater and freshwater, which supports the unique plant and animal species found there.

With reduced water availability, the water levels in marshes would decline, leading to increased salinity and changes in the vegetation composition. Marsh grasses and other wetland plants may struggle to survive, affecting the primary producers in the food web.

The decrease in primary producers would cascade through the food web. Herbivores, such as marsh rabbits or marsh snails, may experience food shortages and face population declines.

This, in turn, would impact predators such as marsh hawks or alligators that rely on these herbivores as their prey.

As the population of higher trophic-level organisms decreases, it can disrupt the entire food web, affecting the stability and biodiversity of the ecosystem.

Furthermore, drought-induced habitat changes may force certain species to migrate or seek alternative resources, potentially leading to increased competition for limited food and space. This competition can further disrupt the balance of the food web.

In summary, a severe drought in the Georgia marshland ecosystem would result in reduced water availability, changes in vegetation, and disruptions in the food web.

The impacts would be felt across trophic levels, affecting primary producers, herbivores, and predators, and potentially leading to population declines and alterations in species interactions.

Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.

Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.

Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.

Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.

The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.

Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.

This shows that Carlton has an impaired absolute threshold.

He could not detect the smallest quantity of a stimulus to differentiate between the smells.

Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.

This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.

Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.
