Rocks deteriorating the ocean floor

Explanation:

As rocks scrape past the ocean floor they chip away at it smoothing it (erosion) out but due to continental drift and magma rising and cooling it causes the new igneous rock forms on the ocean floor making it rough and rugged.

Answer:

water, compost , and chemical fertilizer

Water, compost , and chemical fertilizers is the best for maintaining the long-term health of farm soil.

Chemical fertilizers, such as urea, diammonium phosphate (DAP), and single superphosphate (SSP), are used to maintain the shortage of nitrogen, phosphorus, and potassium in the soil.

Most fertilizers that are commonly used in agriculture contain the three basic plant nutrients: nitrogen, phosphorus, and potassium. Some fertilizers also contain certain "micronutrients," such as zinc and other metals, that are necessary for plant growth.

Chemical fertilizers will nourish your plant, but the minerals will not linger in your soil. By creating rich, nutrient-dense soil with organic materials, your lawn will have a better chance of thriving on its own tapping into stored minerals when needed.

Explanation:

Malabsorption of some minerals, including calcium, magnesium, and zinc often occurs because the minerals form soaps with the unabsorbed fatty acids.

Minerals are parts of the nutrients made in the body or gotten from food sources that are essential for the maintenance of health and growth.

Examples of minerals are calcium, magnesium, and zinc which are capable of forming soap with fatty acids in a reaction called saponification.

Therefore when they are unabsorbed in the body, minerals form soaps with the unabsorbed fatty acids.

Answer:

The fewer fish the less that can reproduce.

Explanation:

marine mammals with a slower reproductive rate are especially sensitive to disturbance , environmental changes and anthropogenic sources of stress because when populations of these organisms decline, recovery is especially slow . it takes a significant amount of time for these animals to reach reproductive maturity and they are commonly heavily invested in raising only one or two young ones every two to three years on average . therefore , populations of marine mammals with slow reproduction are in imminent danger when multiple sources of envirnmental pressure are acting in tandem over an extended period of time . The fewer fish the less that can reproduce.

More the reproductive rate, lesser the extinction and lesser the reproductive rate, more is the extinction.

The reproduction rate measures the conditions under which generations are replaced. This calculation can be made taking account of mortality (net reproduction rate) or without mortality (gross reproduction rate).

Extinction is a situation in which something no longer exists.

When the reproductive rate of marine mammals will be less, they will not be able to cover up the loss/death of their species caused by any reason and will ultimately lead to extinction.

Answer:

The colors we see are the result of which wavelengths of light are reflected back to our eyes. Veins appear blue because blue light is reflected back to our eyes.

Blue light does not penetrate human tissue as deeply as red light does. As a result, veins that are close to the surface of the skin will be more likely to reflect blue light back to the eye.”

In short, our veins appear blue because of a trick that light plays on our eyes and how the light interacts with our body and skin. All color works this way as light is a combination of all colors and when it reflects off of certain materials, it absorbs some colors and bounces back others to our eyes.

Invasive species are usually competitors, predators, high reproducers, and are mostly introduced by humans activities.

They are plant or animal species that invade ecosystems.

They are mostly introduced to ecosystems from another ecosystem and once they establish themselves, end up out-competing native species for resources.

Invasive species generally have high reproductive capacity and efficient dispersal mechanisms.
