Explanation:

For water molecule all options are correct here.

What is the structure of a water molecule ?

Water occupy around 70% of the earth’s surface, it make up about 95% of the living organisms.

Each water molecule is composed  up of one molecule of oxygen and two molecules of hydrogen by forming  a covalent bond .

A strong bond of attraction between nucleus of the oxygen nucleus and  electrons of hydrogen has been seen which form an angle 105° between hydrogen atoms

Due to this asymmetry in shape water has a strong property of strong dipole movement  that is highly polarized molecule with both positive and negative charges.

It is  very cohesive in nature by developing a  strong bonding with itself, and also adhesive in nature.

It shows high boiling point as hydrogen- oxygen bond highly polar and

Hydrogen atoms are present at two corners with a  tetrahedron shaped which gives water a high polarity.

Answer:

The final volume is the sum of the initial volume and the volume of the object.

Explanation:

Since we know that the volume of the object is the difference between the final and the initial volume, let the volume of the object be ∆V, let the initial volume be V1 and let the final volume be V2.

From;

∆V= V2 - V1

V2= ∆V + V1

Explanation:

DNA strand:   5' ACATCGACGCGCGCA 3'

compliment:  3' TGTAGCTG CGCGCGT 5'

DNA strands are antiparallel which means that if you're given a 3' to 5' strand, the complementary DNA strand will be 5' to 3'. If you are given a 5' to 3' strand, the complementary strand will be from 3' to 5'.

The other thing to remember for DNA complementary strands only is:

- A always pairs with T

- G always pairs with C

(for DNA only!!!!) This is one of Chargaff's principles.

If you're asked to find the RNA sequence, A pairs with U. not T! Thymine does not apply to RNA. G still pairs with C though.

What has OOMPAH LOOMPA GENETICS?

Oompah Loompa Genetics refer to the unique characteristics of the fictional race of small people from Roald Dahl's 1964 novel Charlie and the Chocolate Factory. The Oompah Loompas are described as having orange skin, green hair and wearing white clothes. The genetics behind this unique appearance are unknown and the Oompah Loompas are believed to be a fictional race. From the descriptions given in the book, it is likely that the Oompah Loompas have mutated traits or a combination of traits of different races or species, giving them their distinct appearance. It is also possible that they have some form of genetic manipulation, perhaps from the eccentric chocolatier, Willy Wonka. Whatever the case may be, the Oompah Loompas are a unique and fascinating race with an interesting genetic makeup.

The onion skin cells doesn't have chloroplasts because the bulb of the onion grows underground.

Chloroplasts produce energy through photosynthesis and oxygen-release processes, which sustain plant growth and crop yield. As such, chloroplasts are responsible for the biosynthesis of active compounds such as amino acids.

The most important function of the chloroplast is to synthesise food by the process of photosynthesis. Absorbs light energy and converts it into chemical energy. Chloroplast has a structure called chlorophyll which functions by trapping the solar energy.

The two main functions of chloroplasts are to produce food (glucose) during photosynthesis, and to store food energy. Most leaves appear green because the chloroplasts in plant cells give plants their green color.

Explanation:

A prospector would look for deposits of magnetite rather than deposits of iron because magnetite is an ore that contains the element iron.

Magnetite is also a common indicator mineral for many types of mineral deposits, such as iron oxide-copper-gold (IOCG) deposits.

In addition, magnetite is a magnetic mineral, which means that it can be detected using magnetic surveys. This makes it easier for prospectors to locate and map out potential deposits of magnetite, and therefore, potential sources of other valuable minerals that may be associated with it.

Iron deposits, on the other hand, are often more difficult to detect on their own because they do not have any distinctive physical or chemical properties that make them easy to identify. They can be found in a variety of rock types, and may not be visible on the surface. However, if a prospector does find magnetite, it may be an indicator that there are also iron deposits in the area.

Contaminated water is a type of water that is harmful to human beings due to the presence of harmful substances, pollutants, or impurities that make the water unsafe for drinking or other household uses. The characteristics of contaminated water can be identified through various indicators, which can either be physical, biological or chemical.

Physical indicators are visible and may include color, taste, and odor, while biological indicators are not visible and may include bacteria, viruses, and protozoa. Chemical indicators may include heavy metals, pesticides, and organic compounds, among others.

Physical Characteristics: Physical characteristics of contaminated water include cloudy or turbid appearance, unusual taste or odor, or discoloration of the water. The color may range from yellow to brown, blue to green, or even black.

Biological Characteristics: Biological characteristics of contaminated water include the presence of bacteria, viruses, or protozoa. These microorganisms can cause diseases such as diarrhea, typhoid, cholera, and dysentery.

Chemical Characteristics: Chemical characteristics of contaminated water include the presence of heavy metals such as lead, arsenic, or cadmium. Pesticides and fertilizers can also contaminate water and affect human health. Organic compounds like benzene and toluene can also be present in contaminated water, which can lead to health problems such as cancer and nerve damage.

Therefore, it is important to test water sources regularly to identify and monitor any contaminants that may be present. This can help prevent health problems associated with the use of contaminated water.

Answer: D not change significantly

Explanation: If you double the amount of enzyme present, the delta G of a reaction will not change. Enzymes are specialized types of proteins used to catalyze or speed up chemical reactions. Although they increase the overall rate of the reaction, they do not affect the net energy change.

Approximately, distance is 150ft. Hence option (B) 150 ft, is correct answer.

The distance a rock has fallen after 3.5 seconds can be determined using the equation for calculating the distance an object has fallen under the force of gravity.

This equation is d = 1/2*gt2, where d is the distance, g is the acceleration of gravity (9.8m/s2), and t is the time (3.5 seconds). Plugging in these values, the distance d is equal to 242.5 ft.

Therefore, the rock has fallen approximately 150 ft after 3.5 seconds.

The distance a rock will fall in 3.5 seconds depends on its initial velocity and the acceleration due to gravity.

Assuming the initial velocity is zero, the rock will be accelerating at a rate of 32 ft/s2 due to gravity.

Therefore, the distance the rock has fallen after 3.5 seconds can be calculated using the equation d = 1/2at2.

Substituting a = 32 ft/s2 and t = 3.5 s into the equation yields a distance of 150 ft. In conclusion, the rock has fallen approximately 150 ft in 3.5 seconds.
