Answer: There is no change in the chlorophyll A and B over time, concentration would not decline in late autumn.

Explanation:

Evergreen are trees whose foliage is green throughout the year, so they do not shows senescence during autumn. This green color is due to the presence of chlorophyll, which is a photosynthetic pigment found in chloroplasts of plant cells. The pigment is located inside the membranes of the tilacoids of the organelle. It also fulfills the function of carrying out photosynthesis, using light energy and water to fix carbon and be able to manufacture glucose which is the source of energy.  

There are four types of chlorophyll:

These trees, having green leaves all year round due to the presence of chlorophyll A and B that is produced all year round, are capable of carrying out photosynthesis throughout the year, even in low sunlight, as occurs during autumn and winter. Because of this, it the tree looks the same at any time of the year.

So, there is no change in the chlorophyll A and B over time, concentration would not decline in late autumn.

Melatonin hormone produced in the brain's pineal gland, is secreted at about 9:30 p.m. in younger adolescents and approximately an hour later in older adolescents.

How significant is the pineal gland?

The pineal gland, which controls the body's circadian rhythms, is essential to the body's internal schedule. Circadian rhythms are the body's natural daily cycles, which include signals that cause people to feel sleepy, awake, and aware at roughly the same times each day.

Your brain releases the hormone melatonin in reaction to darkness. It aids in sleep as well as the timing of your circadian rhythms (24-hour internal schedule). Light exposure at night can prevent the creation of melatonin. Less frequent melatonin side effects may include momentary depressive feelings, tremors, anxiety, cramps in the abdomen, irritability, decreased alertness, bewilderment, or disorientation.

Answer: 4) white blood cells

Explanation:

The bleeding from a small cut soon stops due to the release of platelets. Hence, option 1 is the correct answer. These are cell fragments of megakaryocytes.

When there is a cut, blood comes out of that organ. To prevent blood loss, the body has certain mechanisms. This mechanism is called blood clotting.

In the blood, different cells are present. Red blood cells (RBC), white blood cells (WBC), and megakaryocytes are present in the blood. The red blood cells supply oxygen to the different tissues. It consists of hemoglobin. The white blood cells protect the body from pathogens. Eosinophils, neutrophils, basophils, monocytes, etc. are white blood cells ( WBC) 

Megakaryocytes are the cells that form platelets. These platelets are cell fragments of megakaryocytes. When a cut occurs, these platelets come to the site along with other clotting factors such as fibrinogen to form a network-like structure. Due to this network, the blood cells can't come out, and blood loss stops.

Hence, option 1 is the correct answer as platelets prevents the blood loss. Other options are incorrect.

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.

When compaction and cementing happens then, a sedimentary rock is made. The rock is made when layers of minerals are stacked upon each other. These minerals include dirt, soil, sand, and other stuff. Overtime these minerals will make the layers that you see in a sedimentary rock. So, the older minerals will be on the bottom while the younger minerals will be on the top.

The Sedimentary rocks refers to the type of rock that is formed from pre-existing rocks or pieces of once-living organisms. They mainly emerged from deposits that accumulate on the Earth's surface and often have distinctive layering or bedding.

The common types of sedimentary rocks include sandstone, limestone, and shale. They often start as sediments carried in rivers and deposited in lakes and oceans and when buried, the sediments lose water and become cemented to form rock.

If F = -F represents Newton's 3rd Law, then "-F” represents the opposite force. Therefore, the correct option is B.

Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction. This means that if an object A exerts a force on object X, then object X will exert an equal and opposite force on object A.

Mathematically, the given statement can be expressed as:

Fₐₓ= -Fₓₐ, where Fₐₓ is the force exerted by A on X, and Fₓₐ is the force exerted by X on A.

In the given statement, F = -F means that the force exerted by object A on object X  is equal in magnitude but opposite in direction to the force exerted by object X on object A.

Therefore, “-F” represents the opposite force, which is equal in magnitude but opposite in direction to the original force. Therefore, the correct option is B.
