What is a DNA probe?
Answer:
In molecular biology, a hybridization probe is a fragment of DNA or RNA of variable length which can be radioactively or fluorescently labeled. It can then be used in DNA or RNA samples to detect the presence of nucleotide substances that are complementary to the sequence in the probe.DNA probes are stretches of single-stranded DNA used to detect the presence of complementary nucleic acid sequences (target sequences) by hybridization. DNA probes are usually labelled, for example with radioisotopes, epitopes, biotin or fluorophores to enable their detection.

Our experiment was to keep one seedling set in a light place and the other set in a closed cardboard box. So my question is to explain why it is important to keep one set of seedlings in the light. I hope to get a perfect answer
Answer:
To examine the importance of light to a plant's growth.
Explanation:
To give a background to this question, I will define a key term "Photosynthesis". Photosynthesis is a compound word made up of photo (which means "light") and synthesis (which means "to put together").
It is the process by green plants use sunlight to obtain nutrients from carbon dioxide and water.
The experiment us meant to examine the effect of deprivation of sunlight on a plant's growth.
Therefore, the essence of keeping one set of seedlings in the light is to compare if there is any difference in growth between the seeding kept in the dark cupboard and that kept in the light.
This enables us to conclude whether or not light is important for the growth of a plant.

C. Stay calm, watch the child's actions, and try to imagine what the child is feeling
D. Let the child manage the stress by him or herself without interfering
Answer:
B
Explanation:
Answer:
C. Stay calm, watch the child's actions, and try to imagine what the child is feeling
Explanation:
Infants and toddlers are not able to communicate their feelings and emotions effectively. Caregivers need to observe the child's actions and body language to understand what the child is feeling. By staying calm and observant, caregivers can provide the right amount of support to help the child manage stress.

During the process of mountain building, earthquakes sometimes occur along continental-continental convergent boundaries. Which statement best describes the motion of the plates along these boundaries that causes the earthquakes?
Answer:
Although you have not put the answer options, the movement of the plates in the situation shown above occurs with the approach of their continental plates that collide and bend due to the impact.
Explanation:
The converging movement of the plates indicates that two plates are moving towards each other until they collide. When these two plates are continental, the movement is called continental-continental convergent.
As the two continental plates have the same density, the impact between the two causes them to bend and not sink into each other.
Answer:
D) the plates smash together with no subduction

Why does light from the sun melt the plastic when light from the desk lamp does not
Answer:
Because the sun gives off a type of light that carries energy, and light from the desk lamp does not.
Explanation:
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
Lamps are electrical devices that use electrical energy in the form of electrical current.

Explanation:
Sheila weighs 60 kg and is riding a bike. Her momentum on the bike is 340 kg • m/s. The bike hits a rock, which stops it completely and throws Sheila forward onto the pavement. If there is no net force on the system, what is Sheila’s velocity immediately after she is thrown from the bike?
Answer:
5.7 m/s
Explanation:
The computation of Sheila 's velocity right after she gets thrown out of the bike is shown below:
1) The Physical principle: conservation of momentum.
If there is no net external force operating on a system, so the system's total momentum is conserved
The momentum, p, is a vector magnitude that is determined as the product of the mass by the velocity:
P = mv.
2) Taking into account therefore that there is no net force on the device, Sheila and the momentum of the bike are the identical pre and post collision.
Based on this, the calculation is as follows
Momentum before the collision:
[tex]P_1 = (mass\ of\ Sheila + mass\ of\ the\ bike) \times velocity[/tex]
[tex]P_1 = (60kg + m) \times v_1[/tex]
= 340 kg m/s
Now Momentum after the collision:
[tex]P_2 = mass\ of\ sheila \times velocity\ of\ Sheila + mass\ of\ the\ bike \times velocity\ of\ the\ bike[/tex]
[tex]P_2 = 60kg \times v_2 + m \times 0 = 60kg \times v_2[/tex]
[tex]P_1 = P_2[/tex]
[tex]= (60kg + m) \times v_1[/tex]
[tex]= 60kg \times v_2[/tex]
[tex]= 340 kg .\ m/s[/tex]
[tex]= 60kg \times v_2[/tex]
[tex]v_2 = \frac{340\ kg .\ m/s }{60\ kg}[/tex]
= 5.7 m/s
The velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.
The given parameters;
mass of Sheila, m = 60 kgmomentum of Sheila, P = 340 kg.m/sThe velocity of Sheila immediately after she is thrown from the bike is calculated as follows;
P = mv
where;
v is the velocity Sheila
[tex]v = \frac{P}{m} \\\\v = \frac{340}{60} \\\\v = 5.67 \ m/s[/tex]
Thus, the velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.

how to ecosystem services affect human sustainability
Answer:
Ecosystem services play important role in human sustainability. Ecosystem services include provisioning,regulating, supporting, and cultural.
Provisioning include production of food and water which is one of the essential requirement for human survival and provided by ecosystem in the form of plants or other animals. No food means no human life.
Regulating may include the control of disease and climate.Humans at different regions are susceptible to particular temperature and diversity in Climate provide required atmospheric condition for human survival. Climatic changes causes global warming which bring many diseases and temperature fluctuations that affect human sustainability. Diseases decreases human population and affect human susceptibility so ecosystem controls the diseases that increases chance of human survival. More diseases with no medicine may result into high mortality rate.
Supporting, such as oxygen production and nutrient cycles are important factors that support human sustainability because nutrients provide energy to humans to do work and oxygen is must for their living.
Cultural involve recreational and spiritual benefits. Recreational and spiritual benefits include regulation of physical and mental health and social interaction with other people that keeps a human healthy and happy for living a good life.
Hence, ecosystem services promote and affect human sustainability.
