What are non examples of Asexual reproduction

Answers

Bacteria and Binary Fission-
Many single-celled organisms rely on binary fission to reproduce themselves. All bacteria reproduce by binary fission.
Budding and Hydras-
Hydras are a type of freshwater cnidarian related to jellyfish, sea anemones and corals. Hydras reproduce asexually by developing small, genetically identical polyps that protrude from the parent. These polyps break off from the parent to form a new organism in a process called "budding."
Parthenogenesis and Copperheads- Though most of the organisms that use asexual reproduction are invertebrates, several species of vertebrate animals do make use of it. Some, like copperhead snakes, can reproduce asexually as an alternative to their typical sexual reproduction. Through a process called parthenogenesis -- literally "virgin birth" -- copperhead females can give birth to live young without having been inseminated by a male, even when males are available, according to National Geographic. In this form of parthenogenesis, the polar body, or a cell produced alongside the female's egg, acts as a sperm cell and essentially "fertilizes" the egg. Parthenogenesis has been observed in several species of reptiles, birds and sharks, and is especially common in insects.

A remote control car travels at a uniform speed of 3.5 m and reaches its destination in five minutes. How far did the remote control car travel

Answers

The speed of the remote control carriage is uniform = 3.5m / s.
The elapsed time is 5 minutes.
You can use the formula
speed = distance / time.
Clearing the distance, which is what we want to find, we have:
distance = speed*time.
However, the speed is in units of seconds and the time in units of minutes. To perform the operation we need to have everything in the same units.
So.
5minutes x 60seconds / 1minute = 300 seconds
Finally:
distance = 3.5m / s * 300s = 1050 meters.
The remote control car traveled 1050 meters

The earth takes 1 year to revolve around the sun at 1 A.U. distance (an astronomical unit = 93,000,000 miles). If a planet were 4 A.U. from the sun, how many years would it take to make 1 orbit?

Answers

Kepler's third law states that the square of the orbital period is proportional to the cube of the semi-major axis of its orbit. In equation form, P^2 / a^3 = constant. For the earth, (1 y)^2 / (1 AU)^3 = 1, so the constant is 1. For a planet 4 AU from the sun:
P^2 / (4 AU)^3 = 1P^2 = 64P = 8 years

what is the mass of a 4900 N bobsled

Answers

A single kilogram is equivalent to 9.8 newtons, meaning that to find the weight of the bobsled, you would simply divide the weight by 9.8. Doing this we find that the bobsled is 500kg

4900 / 9.8 = 500

Answer:

500 Kg.

Explanation:

The problem is giving us the weight of the object the weight is different from the mass of an object

Weight is the mass of any object multiplied by gravity (the value of gravity is approximately [tex]9.8\frac{m}{s^2}[/tex] ).

The unit of weight are newtons that equals

[tex]N= Kg.\frac{m}{s^2}[/tex]

[tex]W= m.g[/tex]

we cleared the mass of the formula

[tex]W=m.g\\ m=\frac{W}{g} \\ m= \frac{4900N}{9.8 \frac{m}{s^2} }= 500 Kg[/tex]

n the picture of a planet in orbit around its star area a is double that of area b. What is true of the time the planet takes to travel A1A2 as compared to B1B2

Answers

We have that the second law of Keppler applies here; they were the most important laws we had in order to start planetary motion for at least a century and they were:
1) the planets move in ellipses (with one focus on the sun)
2) A line joining the sun and the planet traverses equal areas in equal times
3) The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.

Applying the second law, we get that the time to transverse A1A2 is double the time needed to transverse B1B2 (even though B1B2 is longer, because the planet is closer to the sun, it goes faster). The second law simply states that time is proportional to area in such graphs.

Franklin’s hometown is flooding due to a severe storm. He is evacuating the area in his vehicle. What should he do if he comes across a flooded area or flowing water?

Answers

Franklin must not drive through a flood for there may no road at all under the water, unless he is familiar with the road and the flowing water is below one foot.

Moreover, if negotiating a flooded section of road, he must drive in the middle where the water will be at its shallowest and he must not drive through water against approaching vehicle to consider other drivers.

Franklin should not attempt to cross any areas with flowing water because he could get injured or swept away. Franklin should also not drive on flooded roadways because it can be hard to tell how deep the water is and his vehicle could easily get stuck. If his car does get stuck, Franklin should leave it immediately.

a ball is thrown horizontally from the roof of a building 45m tall and lands 24m from the base what is the initial speed?

Answers

To find the initial speed of a ball thrown horizontally from a 45m tall building, we first calculate the time of flight using the vertical motion equation and then determine the initial horizontal speed using the range and time of flight.

Finding the Initial Speed of a Horizontally Thrown Ball

To calculate the initial speed of a ball thrown horizontally from the roof of a building that is 45 meters tall and lands 24 meters from the base, we can use the kinematic equations of motion for projectile motion.

Step 1 - Time of Flight

To find the time it takes for the ball to hit the ground, we use the vertical motion equation:

s = ut + 0.5*at^2

Since the ball is thrown horizontally, the initial vertical velocity (u) is 0 m/s. s is the height of the building (45 m) and a is the acceleration due to gravity (9.8 m/s2).

By substituting the known values, we can solve for t.

Step 2 - initial Horizontal Speed

Now, knowing the time of flight, we can find the initial horizontal speed(vx) using the horizontal motion equation:

Range = vxt

The range is given as 24 m. Therefore, vx = Range / t.

Final Answer

After calculating, we get the initial horizontal speed of the ball, which is necessary to cover the horizontal distance within the derived time of flight.

the wasp’s stinger - protection against predators

The wasp stinger generally exhibit toxic substance or allergy causing agent which the wasp use when it finds a predator around it.

the peacock’s bright plumage - attraction to obtain a mate

The male peacock exhibit bright and showy feathers which is a phenotypic advantage for attraction of female mates for copulation. This phenomena is called as sexual selection.

the owl’s large eyes - help to search for food

The owl's large eyes allows the night vision. There are many rods and cones present in the eyes of the owl so as to allow better vision in night and allow it to observe and capture prey.

the bear’s fur - maintain homeostasis

The bear's fur are insulating in nature that means it does not allow the entry of external air. Hence, helps in retaining the heat in the body in otherwise cold environment. Therefore, helps in maintaining the homeostasis (the tendency of the body retain it's constant internal environment as compared to changing external environment).

Terrestrial rocky planets are mostly made of metals, which need higher temperatures than gases in order to condense.
According to the Solar Nebula theory, temperatures high enough to condense metals were closer to the Sun, while towards the outside of the System, temperatures where lower.
This is the reason why terrestrial rocky planets are closer to the Sun, while gaseous planets are further from the Sun.

Hence, the difference in the composition of the terrestrial planets and the gas giants can be explained by the different condensation temperature in the regions near and far from the Sun during the formation of the Solar System.

n the picture of a planet in orbit around its star area a is double that of area b. What is true of the time the planet takes to travel A1A2 as compared to B1B2

Answers

The Kepler's laws predict the planetary motion, so there are three laws for this, namely:

1. The orbit of a planet is an ellipse with the Sun (the sun is a star!) at one of the two focus.

2. A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.

3. The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.

So, let's use second law. The Sun sweeps out equal areas during equal intervals of time means that if A = B, the time the planet takes to travel A1A2 is equal to the time the planet takes to travel B1B2, but given that A = 2B, then takes twice the time to travel A1A2 compared to B1B2.

What is the electric potential of a 2.2 µC charge at a distance of 6.3 m from the charge? Recall that Coulomb’s constant is k = 8.99 × 109 N • ___ V
What is the electric potential at a distance of 99 m from the charge?___ V

Answers

According to Edge, the answers is

3100 V

and

200v

Final answer:

The electric potential of a 2.2 µC charge at a distance of 6.3 m is 3.14 × 10^6 V. At a distance of 99 m, the electric potential is 2.02 × 10^4 V.

Explanation:

To calculate the electric potential, we can use the equation V = kQ/r, where V is the electric potential, k is Coulomb's constant (8.99 × 10^9 N • V^-2 • m^2 • C^-2), Q is the charge, and r is the distance from the charge.

For a charge of 2.2 µC at a distance of 6.3 m, we can plug in the values to find:

V = (8.99 × 10^9 N • V^-2 • m^2 • C^-2)(2.2 × 10^-6 C)/(6.3 m) = 3.14 × 10^6 V

Similarly, for a distance of 99 m, the calculation would be:

V = (8.99 × 10^9 N • V^-2 • m^2 • C^-2)(2.2 × 10^-6 C)/(99 m) = 2.02 × 10^4 V

the half-life of iodine-131 is 8 days. if a sample originally contains 0.96 g of the isotope, how much will remain after 16 days

Answers

The half-life of a substance is the time the substance takes to decay until the amount of the sample is half of its initial amount.

In this problem, the half-life of iodine-131 is 8 days. This means that after 8 days, only half of the initial sample will be left. After another 8 days (16 days), the sample will be reduced by another factor 1/2, so only 1/4 of the initial sample will be left.

Since the initial sample was 0.96 g, after 16 days the amount of iodine left is
[tex]m= \frac{1}{4}(0.96 g) =0.24 g[/tex]

After 16 days, there will be approximately 0.24 grams of iodine-131 remaining in the sample.

How the half-life of iodine

The half-life of iodine-131 is 8 days, which means that every 8 days, the amount of iodine-131 in a sample will be reduced by half.

After 16 days, which is two half-lives, the amount of iodine-131 remaining can be calculated as follows:

First half-life: 0.96 g / 2 = 0.48 g remaining

Second half-life: 0.48 g / 2 = 0.24 g remaining

Therefore, after 16 days, there will be approximately 0.24 grams of iodine-131 remaining in the sample.
