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

Elisabeth is an oceanographer. On which of the following research expeditions would she travel from the photic zone to the aphotic zone?
A.) A snorkel trip from the intertidal zone to 55 feet off the beach
B.) A scuba trip from the surface down 100 feet
C.) A submersible traveling from the ocean surface to the abyss
D.) A research vessel from the beach to the open ocean
A research expedition traveling from the photic zone to the aphotic zone, is a submersible traveling from the surface of the ocean to the abyss.
What is aphotic zone and photic zone?Depending on the lighting, the waters are divided into:
PHOTIC ZONE → up to 200 m deep. DYSPHOTIC ZONE → between 200 m and 400 m deep. APHOTOTIC ZONE → below 400 m depth.With this information, we can conclude that a research expedition traveling from the photic zone to the aphotic zone, is a submersible traveling from the surface of the ocean to the abyss.

Which of these types of fertilizers is the best for maintaining the long-term health of farm soil? (select all that apply) organic matter compost chemical fertilizers water, i have no idea what subject this is in so i put biology.
Answer:
water, compost , and chemical fertilizer
Water, compost , and chemical fertilizers is the best for maintaining the long-term health of farm soil.
What do you mean by chemical fertilizers?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.

if we have red veins and red blood how do we have blue veins in our bodies FIRST ONE TO ANSWER AND EXPLAIN GETS BRAINILEST PLEASE HELP
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.

7 Infer Before scientists were able an to view and study the ocean floor directly , why might they have expected the ocean floor to be smooth and flat ?
Answer:
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.
When thinking about this think about a pebble on the beach, what it is?
rounded due to erosion just as scientists thought the ocean floor would be.
