Answer:
Reproductive cloning involves creating an animal that is genetically identical to a donor animal through somatic cell nuclear transfer. In reproductive cloning, the newly created embryo is placed back into the uterine environment where it can implant and develop. Dolly the sheep is perhaps the most well known example. In therapeutic cloning, an embryo is created in a similar way, but the resulting "cloned" cells remain in a dish in the lab; they are not implanted into a female's uterus.

Trees are being felled at an alarming rate by people. Forests are home to numerous animals and people, and by removing trees from them, we are destroying their habitat and depriving them of a safe haven.
What is community conservation?Community conservation refers to a strategy for protecting the environment that acknowledges local residents' rights to manage wildlife or gain both direct and indirect benefits from it.
The gorillas' habitat, the forest, is being destroyed by humans. Additionally, people are harming these creatures, and if this continues, gorillas may become extinct.
There won't be as many resources from trees, like paper, if people cut down less of them, therefore prices could rise.
Prices for tourists will increase if fewer gorillas are still alive. That won't benefit visitors since they will have to pay more, and since some individuals don't have a lot of money, there will be fewer visitors.
Thus, this way, community conservation is mandatory.

The word gymnosperm comes from two Greek words: gymno, meaning bare, and sperm, meaning_____ . Unlike other seed plants, gymnosperms do not have a protective _______ around their seeds. Most gymnosperms have needle-like or scale-like ______.
Answer:
Seed, Fruit, Leaves
Explanation:
Gymno, meaning bare, and sperm, meaning seed. Unlike other seed plants, gymnosperms do not have a protective fruit around their seeds. Most gymnosperms have needle-like or scale-like leaves.
What are gymnosperms?A relatively tiny class of plants known as gymnosperms produce seeds and lack flowers. This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.
Gymnosperm can also be referred to by the less common word acrogymnospermae. It's a broad name for plants like conifers, ginkgo, cycads, and gnetophytes that you probably already know about. The word "gymnosperm" has Greek roots. The tube cell, the generative cell, and two prothallial cells make up the gymnosperm pollen grain's four cells.
Conifers make up the majority of the plant species in the gymnosperm family. In contrast to angiosperms, which produce flowers, gymnosperms create cones as their reproductive organs. Gymnosperms primarily consist of conifers, such as pine trees.

1. You are floating in a canoe in the middle of a swimming pool. Your friend is at the edge of the pool, carefully noting the level of the water on the side of the pool. You have a bowling ball with you in the canoe. If you carefully drop the bowling ball over the side of the canoe and it sinks to the bottom of the pool, does the water level in the pool rise or fall?
Answer:
lower
Explanation:
When you move the ball from your canoe to the water causes the water level to fall
If you carefully drop the bowling ball over the side of the canoe, and it sinks to the bottom of the pool, the water level in the pool will fall.
How to measure water level?Both the bowling ball and the canoe will float on top of the water when they are in a canoe because they will displace more water than they can hold. However, if dropped, the ball will plummet to the bottom of the pool.
The bowl sinks because it is denser than water. The ball will in this scenario move less water than its own volume.
Therefore, when the ball is with you in the canoe in the second scenario, the volume of water displaced will be less than in the first example. Consequently, lower volume
Therefore, the water level in the pool will drop if you carefully toss the bowling ball over the side of the canoe and let it land at the bottom of the pool.

- Un automóvil parte del reposo y acelera uniformemente hasta alcanzar una rapidez de 0,255km/h en un tiempo determinado de 3/4 min. Determinar su aceleración y la distancia recorrida.
Answer:
a). la acelaración del automóvil es [tex]1.574x10^{-6}km/s^{2}[/tex]
b). la distancia recorrida por el automóvil es [tex]1.59x10^{-3}km[/tex]
La aceleración puede ser encontrada por medio de la ecuación cinemática que corresponde a un movimiento rectilíneo uniformemente variado.
[tex]a = \frac{v_{2}-v_{1}}{t}[/tex] (1)
Donde [tex]v_{2}[/tex] es la velocidad final y [tex]v_{1}[/tex] es la velocidad inicial.
La velocidad inicial del automóvil sera cero ([tex]v_{1} = 0[/tex]) ya que parte del reposo.
Antes de remplazar los valores en la ecuación 1 es necesario expresar el tiempo en unidades de segundos.
[tex]t = 0.75min \cdot \frac{60s}{1min}[/tex] ⇒ [tex]45s[/tex]
La rapidez final puede ser expresada en unidades de [tex]km/s[/tex]:
[tex]v_{2} = 7.083x10^{-5}km/s[/tex]
[tex]a = \frac{7.083x10^{-5}km/s - 0km/s}{45s}[/tex]
[tex]a = 1.574x10^{-6}km/s^{2}[/tex]
Por lo tanto, la acelaración del automóvil es [tex]1.574x10^{-6}km/s^{2}[/tex]
Luego para calcular la distancia se puede utilizar la siguiente ecuación.
[tex]d = v_{1}t + \frac{1}{2}at^{2}[/tex] (2)
[tex]d = (0km/s)(45s) + \frac{1}{2}(1.574x10^{-6}km/s^{2})(45s)^{2}[/tex]
[tex]d = 1.59x10^{-3}km[/tex]
Por lo tanto, la distancia recorrida por el automóvil es [tex]1.59x10^{-3}km[/tex]

Animals have different types of respiratory systems depending on the environment of their habitat. Fish live in the water and use gills to breathe. Humans who live on land, breathe air through their lungs. Identify the similarities between lungs and gills.
Answer:
1. Both are respiratory organs found in vertebrates.
2. Both enable the inhalation of oxygen and exhalation of carbon dioxide in the bodies of their host.
3. Respiratory membranes present in both make the exchange of gases easier.
4. Blood vessels found around them enable the breathing process.
Explanation:
Gills are respiratory organs which can be found in animals that live in water. These include fishes, amphibians like frogs, anthropods like insects, and annelids like worms. Gills are surrounded by respiratory membranes known as gill lamellae which have a large surface area that makes breathing easier. Blood vessels also are found around gills.
The lung is also a respiratory organ found in humans. It runs from a windpipe known as the trachea and branches into bronchi which contain the bronchioles. Alveoli ducts contain alveoli sacs and then alveoli which are membranes that enable the breathing process.
Both are similar because they are respiratory organs found in animals with backbones. They are surrounded by blood vessels and membranes that make the breathing process easier.

Background information on thermal energy transfer and conservation of energy
Answer:
Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three methods of thermal energy transfer: conduction, convection, and radiation. ... Convection transfers thermal energy through the movement of fluids or gases in circulation cells.Convection. When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises.

Se tienen 2 vectores cuyos módulos están en la misma razón que 5 y 2. Si cuando forman 53º su resultante mide 3√29u, ¿Cuánto mide el mayor vector?
Answer:
|v2| = 3.27
Explanation:
You have two vector v1 and v2. The relation between the magnitudes of both vectors is given by:
[tex]\frac{|v_1|}{|v_2|}=\frac{5}{2}[/tex]
Furthermore, the projection (the dot product) of one vector on the other one is given by the following formula:
[tex]v_1 \cdot v_2 = |v_1||v_2|cos\theta[/tex]
The dot product between v1 and v2 is 3√29. If you multiply the right hand side of the last equation by |v2|/|v2| you obtain:
[tex]3\sqrt{29}=\frac{|v_1|}{|v_2|}|v_2|^2cos(53\°)[/tex]
you do |v2| the subject of the formula:
[tex]|v_2|=\sqrt{\frac{|v_2|}{|v_1|}\frac{3\sqrt{29}}{cos53\°}}\\\\|v_2|=\sqrt{\frac{2}{5}\frac{3\sqrt{29}}{cos53\°}}=3.27[/tex]
Chuck's car is moving at 65.0m/s when he suddenly accelerates his car at 15.0m/s2 for 3.00s. How far did Chuck, and his car, travel while he was accelerating?
Answer:
x = 265.5 m
Explanation:
To find the distance traveled by the car you first use the following formula:
[tex]v=v_o+at[/tex] (1)
vo: initial velocity = 65.0m/s
a: acceleration = 15.0m/s^2
t: time = 3.00 s
you replace the values of vo, t and a in the equation (1) in order to calculate the final velocity v:
[tex]v=65.0m/s+15.0m/s^2(3.00s)[/tex] = 110 m/s
Next, you use the following formula:
[tex]v^2=v_o^2+2ax[/tex]
x: distance traveled
You do x the subject of the formula and replace the values of vo, v and a:
[tex]x=\frac{v^2-v_o^2}{2a}\\\\x=\frac{(110m/s)^2-(65.0m/s)^2}{2(15.0m/s^2)}=262.5\ m[/tex]
hence, the distance traveled by the car is 265.5 m

Explanation:
A pendulum is swinging back and forth with a period of 2.0 seconds here on Earth. This pendulum is then brought to the Moon, where the acceleration due to gravity is much smaller. What will happen to the period of the pendulum, assuming everything else about it (mass, length, initial swing height, etc) remains exactly the same
Answer: The period will be larger, with T = 4.92 seconds
Explanation:
The period of a pendulum can be obtained by the equation
T = 2*pi*√(L/g)
Where pi = 3.14, L = lenght of the pendulum and g = gravity acceleration.
You can see that the gravitational acceleration is on the denominator, this means that if we decrease the value of g, then the value of T will increase.
In Earth we have that:
2s = 2*3.14*√(L/9.8m/s^2)
L = (1/3.14)^2*9.8 m = 1m
In the moon we have g = 1.62 m/s^2
then the period in the moon is:
T = 2*3.14√(1/1.62) = 4.92s

A circuit has a current of 3 A. How many coulombs of charge will pass by a point in the circuit in 2 seconds?
- 6C
- 5C
- 3/2 C
- 2/3 C
One of these are the answer..
6C
Explanation:
The quantity of charge, Q, passing through an electric circuit is dependent on the electric current, I, and the time taken, t, for the current to flow. It is given mathematically as follows
Q = I x t ------------------------------(i)
Where;
I is measured in Amperes(A)
t is measured in seconds (s)
Q is measure in coulombs (C)
From the question,
I = 3A
t = 2s
Substitute these values into equation (i) as follows;
Q = 3 x 2
Q = 6C
Therefore, the number of coulombs of charge that will pass is 6C

Una barra de longitud de 2 m está cargada uniformemente y tiene una carga total de 5nC. Busqué su potencial eléctrico (relativo acero en el infinito) en un punto que se encuentra a lo largo del eje de la barra y está a 3m del centro de la barra?
Answer:
11.44J/C
Explanation:
To find the electric potential for a point at 3m from one extreme of the bar you use the formula for the electric potential:
[tex]V=\int k\frac{dq}{r}=\int k\frac{dq}{x+3}[/tex]
Where r = x+3 represent the 3m distance of the charge to a point x in the bar.
dq: differential of charge = λdx. λ is the linear charge density.
k: Coulomb constant = 8.98*10^9 Nm^2/C^2
You can write dq as λdx. Furthermore, If you assume that the other extreme of the bar is at origin of the x-axis you can write the integral as follow:
[tex]V=\int_{0}^{2}k\frac{\lambda dx}{x+3}\\\\V=k\lambda \ ln(x+3)|_{0}^{2}=k\lambda (0.510)[/tex]
You replace λ ad k in the last expression:
[tex]V=(8.98*10^9Nm^2/C^2)(\frac{5*10^{-9}C}{2m})(0.510)=11.44\frac{J}{C}[/tex]
hence, the electric potential is 11.44J/C
