Is Colin's evidence relevant to his claim?

Answers

No, Colin's evidence is not relevant to his claim.

Since drone flying is a sport rather than a concern for privacy, Colin's evidence does not support his allegation. Colin gives evidence that is connected to the idea that flying drones is a sport by noting that coordination and technical abilities are required to fly drones. Instead of focusing on giving evidence that supports the idea that drones do not negatively affect people's privacy, Colin offers evidence that is related to the idea that flying drones is a sport. It follows that his argument is weak because it has not been adequately substantiated.

What are the 3 types of point mutations and their effects?

Answers

The three types of point mutations are: addition, deletion and substitution. The effect of these mutations is that the gene sequence is altered that results in variation in gene expression.

Point mutations are the type of mutations where the change in the genetic sequence is due to alteration of a single nucleotide. This change can be the addition, deletion or substitution of the nucleotide. This can however change the entire sequence for the gene expression.

Gene expression is defined as the process by which the genetic information is converted into a functional form that can produce the results inside the body. These processes are transcription and translation.

Rearrange these words and symbols to make the word equation for respiration
water oxygen glucose carbon dioxide + + -->

Answers

Answer:

glucose + oxygen --> carbon dioxide + water

Explanation:

The correct equation is:

               Glucose + Oxygen -> Carbon dioxide + Water + Energy.

Cellular respiration is a process in which different chemical reactions allow the degradation of organic compounds (glucose) to convert them into energy (inorganic substances) for cells.

The process is shown bellow.

Reactants:

Glucose: C6H12O6Oxygen: O2

Products

Carbon dioxide: CO2Water: H2OEnergy: ATP.

This means glucose and oxygen react to become  other components such as carbon dioxide, water and ATP. According to the above, the equation for cell respiration is:

Glucose + Oxygen -> Carbon dioxide + Water + Energy.

The function of a specific enzyme is most directly influenced by its 'physical shape'.

What do you mean by enzymes?

Enzymes are basically proteins that act as catalysts, speeding up chemical reactions in the body. They are essential for life and are involved in many of the body's processes, such as digestion, metabolism, and energy production.

The physical shape of an enzyme is determined by its specific sequence of amino acids, which forms its active site. This active site is the part of the enzyme that binds to substrates and facilitates chemical reactions. The physical shape of an enzyme determines what substrates it can recognize and bind to, which in turn influences the rate at which the reaction occurs. Therefore, the physical shape of an enzyme directly affects its function.

c) The prey population will change unpredictably.
d) The prey population will decreases in size.

Answers

The answer is D, The prey population will decrease in size

If the population size of a predator increases the prey population will decreases in size.

What is Predator-Prey relationship?

Predator-Prey relation refers to the interaction between two species where former is hunting the latter for food.

Example- Lion-Zebra, Bear-Salmon

Predator and Prey respond dynamically to one another. Higher the number of prey it will help to support the higher number of predators.

The key aspect of Predator- Prey relationship is the direct effect the predation has on numbers of their prey.

Predator- Prey relationship depends upon

- Detection of the prey

- Pursuit and capture of the prey

- Feeding

What is Population Dynamics?

The fluctuation in the numbers of a predator species and its prey that occurs over time represent Population Dynamics.

As the prey population decreases due to predator killing, the food available is less and thus the number decline.

The process reverses when the population of predators increases putting population of prey at stake and once the population of prey decreases it eventually result into decrease in the population of the predators as their is not enough population of prey to thrive upon for predators.

Impact:

1. According to Evolution, the predator-prey relationship continues to be beneficial as both the species adapt to ensure they feed without becoming meal for another predator.

2. Maintenance of Biological Diversity of the particular ecosystem and helping to keep the ecosystem stable.

3. The balance of Predator- Prey can be disrupted due to climate change and changes such as drought, urban development, foresting and overuse of resources.

4. Predator- Prey population dynamics can be useful in indicating whether the population of a species could tax the capacity of a particular ecosystem to support their numbers.

5. The knowledge of Predator- Prey population can be used in determining the number of prevailing diseases.

Thus Predator-Prey relations plays vital role in maintaining ecosystem sustainable and balance and any shift in balance would result into disruption of the stability of the ecosystem.

Plant selection is important for a rain garden. Which of the following best describes the types of plants that would be most effective to use in the rain garden in this experimental design to reduce the impact of urban runoff

Answers

Plants that are native to the local area and are well-suited to the soil and climate would be most effective to use in a rain garden to reduce the impact of urban runoff.

These plants have deep root systems that help to absorb and filter water, reducing the amount of runoff that enters local waterways. They also help to reduce erosion and improve water quality. Additionally, plants that are drought-tolerant and able to withstand periods of standing water would be beneficial, as rain gardens can hold water for extended periods. It is important to note that the choice of plants will depend on the local conditions and the experimental design of the rain garden, for example, the pH of the soil, the amount of sun exposure, and the size and location of the rain garden. An expert in the field of horticulture or hydrology would be best suited to make recommendations for plants that would be most effective in a given location.

E)​ eat only natural,unprocessed foods.

Answers

The best way for a person to get all the essential nutrients and keep energy intake low is to choose foods with a high nutrient density from each food group and follow the principle of variety in dietary intake. So the correct option is d.

Nutrient density refers to the amount of essential vitamins and minerals that a food provides in relation to the number of calories it contains. Foods that are high in nutrient density, such as fruits, vegetables, lean proteins, and whole grains, are more nutrient-rich and energy-dense than foods that are high in calories but low in nutrients, such as processed foods and sweets.

Following the principle of variety in dietary intake means eating a variety of foods from different food groups to ensure that you get all the essential nutrients your body needs. Eating a variety of foods from the grains group, fruits, vegetables, dairy, proteins and healthy fats will provide the body with all the necessary nutrients.

Do whales breathe oxygen or carbon dioxide?

Answers

Whales are mammals, not fish. This means that, like all land mammals, they breathe oxygen through their lungs.

Whales and dolphins are mammals, and like us, they breathe air into their lungs. Because they do not have gills, they cannot breathe underwater like fish. Whales are mammals just like humans. Therefore, they have lungs and breathing air on their surface. It cannot extract oxygen from water like fish do with their gills. Whale inhalation is "conscious". The respiratory function of these animals is under the voluntary control of the central nervous system "CNS".

Whales accumulate carbon in their bodies during their long lifespans. When they die, they sink to the bottom of the ocean. Each large whale binds an average of 33 tons of carbon dioxide and removes this carbon from the atmosphere over centuries. Trees, on the other hand, only absorb up to 48 pounds of CO2 per year

B) They are captured comets.
C) They are captured planets.
D) They were formed by condensation and accretion in a disk of gas around the planet.
E) They were formed by giant impacts.

Answers

The origin of almost all the large moons around the jovian planets is D) They were formed by condensation and accretion in a disk of gas around the planet. This is known as the nebular theory.

This theory states that when a new star forms in the universe, it is surrounded by a disk of gas and dust. This disk of gas and dust can form planets and moons around the star

For the jovian planets, this disk of gas and dust is around the planet, rather than the star. As the planet forms and cools, particles in the disk condense and form gas and dust clouds. These clouds eventually form into larger objects which then accrete or collide to form moons around the planet.

This process of condensation and accretion has been observed in various star-forming regions, confirming the nebular theory and making it the most likely source for the large moons of the jovian planets.

The other possible origins of the moons, such as captured asteroids, comets, or planets, cannot be ruled out as some of the moons may have originated from these sources. However, the majority of the moons are believed to have formed from the process of condensation and accretion in a disk of gas around the planet.
