which of the following has a positive affect on soil depletion? A. deforestation , B. overtilling, C. multiple cropping , D. erosion
Answer:
Explanation:
Erosion i think if its wrong im so sorry!:)
Without the functions and benefits provided by soil, human life would not be conceivable. By anchoring roots and storing nutrients, it creates an environment for plants (including food crops and timber wood). Thus, option D is correct.
What erosion has positive impact on soil depletion?While soil erosion brought on by human activities has poured chemicals and toxins into water sources, this is not the case with natural soil erosion.
A 1950s study found that natural soil erosion contributes vital nutrients that support the flourishing of aquatic species. To flourish in. Our water is filtered and cleaned, and it also aids in preventing natural disasters like flooding.
Food production decreases, water supplies dry up, and communities are pushed to relocate to more hospitable areas as a result of land degradation and the expansion of deserts in some areas.
Therefore, erosion has a positive effect on soil depletion.

How does an American Bullfrog gain energy for their growth?
Answer:
They gain energy through respiration.
Explanation:
American Bullfrogs, are predators that have high energy requirements for growth and locomotion, and as they do not produce their own energy-rich food, and they consume primary consumers (birds, fish, rodents, etc.) they are secondary consumers.
Consumers are heterotrophs; they eat or consume organic matter (lipids, sugars, proteins, etc.) made for their energy intake by autotrophs. Autotrophs include plants, microbes, and other species that photosynthesize, while animals, like bullfrogs are heterotrophs.
Heterotrophs derive energy through respiring. They burn fuel in mitochondria- high energy ATP is derived from breaking apart the chemical bonds within carbohydrates like glucose. Like all large animals, they carry out aerobic respiration:
C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
What is the genotype of a person with type A blood, who had a father with type O blood?
IAIB
IAIA
IAi
ii
Answer:
IAi
Explanation:
Blood group in humans is controlled by three alleles namely: iA, iB and i. Alleles iA and iB are dominant over allele i but are co-dominant over one another. The following genotypes with their following blood group are:
iA - blood type A
iB - blood type B
iAiB - blood type AB
i - blood type O
In this case, an individual with type A blood had a father with type O blood. This means that the genotype of the individual will be iAi because the person will inherit the "i" allele from the father but since the "iA" allele is dominant, the type allele will be expressed.
How are humpback whales related to blue whales and minke whales

1. what is the difference between P waves and S waves?
2. How do you determine the difference between when a P wave and an S wave arrives at a seismogram location?
Answer:
P waves travels faster than S waves.
Explanation:
P waves travels faster than S waves. It can travel through any kind of material but s waves only travel through solid medium. P waves are smaller in size than s waves. P waves are the first waves to hit seismographs while the s waves are the second wave arrive at a seismogram location, so we can say that the wave which reach first at a seismogram location is the P waves. The speed of the wave shows which wave arrive first at a seismogram location.

The atomic number of argon is 18 and its mass number is 40. Describe the number and type of particles
found in the nucleus of this atom
Answer:
Argon's atoms have 18 protons, 22 neutrons in its nucleus, orbited by 18 electrons- its atomic mass= P 18 +N 22.
Explanation:
Atoms are the most basic unit of matter that makes up elements. Atoms are composed of electrons orbiting neutrons and protons surrounding a nucleus.
The atomic number is defined as the number of protons in an atom, while the atomic mass is the number of protons and neutrons.
The element Argon, Ar is a noble gas, that exists in a gaseous, inert, state at temperature. Its atoms have 18 protons, 22 neutrons in its nucleus, orbited by 18 electrons- its atomic mass= P 18 +N 22.
There are 8 valence electrons in its outer shell, thus:
Ar is not very reactive, as it does not require electron sharing in atomic bonding. It shows low conductivity, as there are no free electronsplz help....

2 ways us humans can relate to the digestive system. 5-6 sentences plzz and thank u
Answer:
The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.
The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.
Bacteria in your GI tract, also called gut flora or microbiome, help with digestion. Parts of your nervous and circulatory systems also help. Working together, nerves, hormones, bacteria, blood, and the organs of your digestive system digest the foods and liquids you eat or drink each day.
Digestion is important because your body needs nutrients from food and drink to work properly and stay healthy. Proteins, fats, carbohydrates, vitamins, minerals, and water are nutrients. Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair.
Proteins break into amino acids
Fats break into fatty acids and glycerol
Carbohydrates break into simple sugars
