Read each of the following statements. If it describes a process of reproduction, write yes.
If not, write no.
19. New leaves appear on a tree in spring.
20.
An amoeba divides in half.
21.
A bean plant produces seeds in long pods.
22.
Pollen grains are released from a flower.
23.
A sea star produces a new arm after losing one to a predator.
Answer:
New leaves appear on a tree in spring. - NO
An amoeba divides in half. - YES
A bean plant produces seeds in long pods. - YES
Pollen grains are released from a flower. - YES
A sea star produces a new arm after losing one to a predator. - NO
Explanation:
The appearance of new leaves has nothing to do with reproduction but rather regeneration.
An amoeba dividing in half is a form of reproduction known as asexual. Binary fission is a reproductive process in which an organism divides into two and each half develops into new independent organisms.
A bean plant producing seed is part of the reproductive process. After fertilization, the ovule of a flower becomes the seed. A seed in itself is a ripened fertilized ovule.
The release of pollen grains from the anther of a flower to the stigma of a compatible flower in the same or different individuals plants is known as pollination. Pollination is a reproductive process similar to fertilization.
A sea star producing a new arm after losing one to a predator is a regeneration process rather than a reproductive process.
A technique that can be used to separate proteins based primarily on the presence of non-polar residues on their surface is called A) ion-exchange chromatography. B) gel filtration chromatography. C) affinity chromatography. D) gel electrophoresis. E) hydrophobic interaction chromatography.
Answer:
E) hydrophobic interaction chromatography.
Explanation:
Hydrophobic interaction chromatography (HIC) is a methodology used to separate protein molecules depending on their hydrophobicity. HIC enables the separation and purification of proteins by using a reversible interaction between the target protein and the hydrophobic ligand of a HIC resin such as, for example, methacrylate-based beads. This interaction is influenced by the running buffer (high salt concentrations favor hydrophobic interactions). HIC enables the separation of proteins under low denaturation conditions, thereby preserving their biological functions.

Based on observations and facts: Possibly based on folklore, but not necessarily true. Based on opinions, beliefs, or biases: Often support erroneous ideas and may lack scientific basis.Humans use science as a systematic approach to understanding the natural world. Its goal is to eliminate prejudice by using facts and observations to identify and describe underlying concepts and mechanisms. Pseudoscience lacks scientific rigor and relies on unproven claims driven by prejudices or beliefs, resulting in misunderstandings.
The basis of real science is actual data collected by experiment, observation, and application of the scientific process. Myths are important cultural myths that may not reflect scientific reality.

When CFCs are exposed to high levels of UV radiation, what occurs? A. The compound breaks down into nitric oxide and ozone. B. All of these C. A chlorine breaks off and forms a free radical. D. They become ionized and stick together in clumps that become part of smog.
Answer:
C. A chlorine breaks off and forms a free radical
Explanation:
When CFCs are exposed to high levels of UV radiation in the atmosphere, the CFC molecule breaks into chlorine and forms free radicals.
These free chlorine radicals then reacts with ozone molecules and breaks the ozone atom (O3) to form chlorine monoxide and oxygen (O2) molecule.
CFCs are main cause of ozone depletion in the atmosphere.
Hence, the correct option is "C".

Answer:
Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains.
Explanation:
took the test and got it correct
Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains. The correct option is D.
What are Eubacteria?Eubacteria are bacterial counterparts. They go under the name "real bacteria." They lack membrane-bound cell organelles and a genuine nucleus. These are single-celled, tiny creatures.
Contrary to appearances, Eubacteria and Archaebacteria (also known as Archaea) are divided into distinct realms of life based on variations in their genetic make-up, particularly in the sequences of their ribosomal RNA (rRNA).
Together with Eukarya, Eubacteria and Archaebacteria are currently acknowledged as distinct domains of life.
This classification represents the underlying biological differences between the two categories, including variations in cell walls, lipid membranes, and metabolic pathways.
Thus, the correct option is D.

Why is The sun is the ultimate source of energy
for all living organisms.'
Answer:
"Sun is the ultimate energy source for all living organisms."
✴This is because plants need sunlight to make food through photosynthesis. This food is consumed by the animals and human-beings. Carnivores indirectly depend on plants for their food. So, if Sun is not there there will be no life on earth.
✴Secondly, sunlight is a good source of Vitamin-D.
Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated with rickets, a disease in which the bone tissue doesn't properly mineralize, leading to soft bones and skeletal deformities. So if sunlight is not there it can result in loss of Vitamin-D which can cause deficiency diseases.
✴If sunlight is not there there will be no day on Earth. Light will not reach our Earth. Every time there will be only darkness.

Which of the following descries a solution that contain a buffer? A. Sodium hydroxide, a base, is added to the solution, and the pH of the solution becomes higher. B. Citric acid is added to the solution, but the pH of the solution does not change. C. Acetic acid is added to the solution, and the pH of the solution becomes lower. D. Distilled water is added to the solution, and the pH of the solution does not change.
Answer:
B. Citric acid is added to the solution, but the pH of the solution does not change.
Explanation:
In chemistry, buffer solutions or simply called Buffer are solutions that resist a change in pH when an acid or base is added to them i.e they maintain a constant pH. This is as a result of the content of the solution. A buffer may contain a weak acid and its conjugate base (salt) or a weak base and its conjugate acid.
Hence, when a strong base or acid is added to them, they still restore the original pH of the solution due to the reaction that removes or neutralizes the hydrogen or hydroxide ions from the acid and base added to them respectively. This is what happens when Citric acid is added to the solution, but the pH of the solution does not change.
Citric acid, which is an acid, does not practically increase or decrease the pH of the solution. Hence, the solution is called a buffer.
Answer:
Citric acid is added to the solution, but the pH of the solution does not change.

How high is the ceiling in a school gym if a volleyball thrown upward from the floor at 15 m/s barely touches the ceiling before returning to the ground?
Answer:
11.47 m
Explanation:
Givens
vi = 15 m/s
a = - 9.81 m/s^2
vf = 0
d = ?
Formula
vf^2 = vi^2 + 2ad
Solution
0 = (15)^2 + 2*(-9.81)*d
- 225 = 2 * - 9.81 *d
-225 = - 19.62 * d
d = - 225/-19.62
d = 11.47 m
The height of the ceiling in the school gym from the floor is 11.48m.
HOW TO CALCULATE HEIGHT OF A PROJECTILE:
Using one of the equations of motion as follows:v² = u² + 2as
Where;
v = final velocity (m/s)
u = initial velocity (m/s)
a = gravitational acceleration (m/s²)
s = distance traveled (m)
According to this question,
The final velocity (v) of the volleyball is 15m/sThe initial velocity is 0m/sThe acceleration due to gravity is 9.8m/sUsing the formula, v² = u² + 2as, the height of the ceiling (s) can be calculated as follows:
15² = 0² + 2 (9.8) (s)
225 = 0 + 19.6s
225 = 19.6s
s = 225/19.6
s = 11.48m
Therefore, the height of the ceiling in the school gym from the floor is 11.48m
