Answer:

Explanation:

Density is how much matter is contained within a volume. A dense object weighs more than a less dense object that is the same size. An object less dense than water will float on it; one with greater density will sink. The density equation is density equals mass per unit volume or D = M / V.

Explanation:

Density is defined as mass per unit volume so we can calculate density of an object by dividing the mass of the object by the volume of the object.

The density having higher will sink .

Herbivores have more available energy and are at a lower trophic level because they receive energy directly from producers in the Food chain. So, the correct option is A.

A food chain is defined as a linear network of links in a food web that begins with producer organisms and ends at apex predator species, detritivores or decomposer species. It also refers to how organisms are related to each other through the food they eat where each level of the food chain represents a different trophic level.

Producers have 100% of the energy that is derived from the Sun, the next level would receive 10% of it, so herbivores would have a 10% energy level, followed by carnivores at 0.1% and after this another higher trophic level is 0.01%. Herbivores have more available energy and are at a lower trophic level because they obtain energy directly from producers in the food chain.

Therefore, the correct option is A.

The advantages of asexual reproduction except  it produces lots of offspring. Hence option B is correct.

Reproduction is defined as the biological process that creates new, distinct creatures from their "parent" or "parents". Each individual organism exists as a result of reproduction, which is a basic characteristic of all known life. Reproduction ensures the survival of many species on Earth. The species won't be able to survive for very long without reproduction, and it might go extinct very soon.

Fission, budding, fragmentation, and parthenogenesis are all types of asexual reproduction. The population can increase swiftly when the conditions are right. Just one parent is required. It saves you extra time and effort because you don't need a companion. It happens faster than sexual reproduction.

Thus, the advantages of asexual reproduction except  it produces lots of offspring. Hence option B is correct.

Answer:

Raising animals for food requires massive amounts of land, food, water, and energy, causes animal suffering, world hunger and disease. Fifty one  percent or more of global greenhouse-gas emissions are caused by animal agriculture.  It takes almost 20 times less land to feed someone on a plant-based diet than it does on a meat-based diet, since the crops are consumed directly instead of being used to feed animals.  Even though there are enough plant-based foods grown to feed the entire world, the majority of crops (including those grown in countries where people are starving) are fed to livestock for the western nations instead of feeding their own people.  Eating a plant-based diet will help starving people around the world, the environment, your health and the animals!

ok so, as you asked the question you are saying how  we change to a plant based siet help to reduce the world's hunger

1. At divergent boundaries, plates move apart from each other. When this happens, new plate material forms.

2. Two plates pushed together create a convergent fault.

3. If one plate is oceanic and the other continental, the edge of the oceanic plate will be pushed down.

Following things would occur:

1. New plate material forms as a result.

2. A convergent fault is created when two plates are forced together.

3. The margin of the oceanic plate will be pushed downward if one plate is continental and the other is oceanic.

The transfer of energy from one location to another is what's known as a convection current, and it may be thought of as a process. This type of heat transfer is also known as convective heat transfer.

Convection currents in the earth's mantle have been hypothesized to be related to the movement of tectonic plates. This hypothesis has been developed by geologists. The process of rising, spreading, and sinking of gas, liquid, or molten material that is caused by the application of heat is referred to as convection currents.
