In good-quality surface soil, approximately what percentage of the volume is made of mineral and organic matter?

Answers

Answer 1

Answer:

The chemical composition of the soil, the topography, and the presence of living organisms determines the quality of soil. In general, soil contains 40-45% inorganic matter, 5% organic matter, 25% water, and 25% air.

Explanation:

Answer 2

Answer:

50 percent

Explanation:

The composition of soils varies from place to place. But in good-quality surface soil, mineral and organic matter make up about half the volume. The other half is made of pore spaces that are filled with air and water.

Venn diagrams are used for comparing and contrasting different topics. The overlapping sections show characteristics that the topics have in common, and the sections that are unique to each topic show the characteristics apply to only that topic. Overlapping circles are labeled solid on top, liquid at right, gas at left, with the intersection of all three labeled state of matter. Which Venn diagram accurately describes what characteristics of solids, liquids, and gasses could be added to this diagram? Overlapping circles are labeled definite shape most dense at top, mid-level density at right, definite volume least dense at left, with the intersection labeled state of matter.

Answers

Image is not attached in the question, so the required image is attached below.

Answer:

Third image

Explanation:

The third image shows the correct venn diagram for of solids, liquids, and gasses.

In the diagram, gases have the least dense of the three main states of matter.

Solids and liquids have definite volumes which is common in both the states.

Liquids have characteristic of mid-level density and solid are most dense. Solids have definite shape while other two states do not have.

The second Venn diagram correctly represents the characteristics of solid , liquid and gas.

Solids are the most dense of all phases of matter with a definite volume and shape while.

Liquids are less dense with definite volume but without definite shape. and.

Gases have no definite shape and no definite volume and it is the least dense of all phases of matter.

Venn diagram is a pictorial form of representing data for better understanding

Hence we can conclude that the second Venn diagram correctly represents the characteristics of solid , liquid and gas

The function of triglycerides is_________
A. store information.
B. to form semipermeable membranes.
C. to transport substances in and out of cells.
D. to store energy.
E. to form semipermeable membranes and to transport substances in and out of cells.

Answers

Answer:

D. to store energy

Explanation:

Triglycerides are a type of fat (lipid) found in your blood. When you eat, your body converts any calories it doesn't need to use right away into triglycerides. The triglycerides are stored in your fat cells. Later, hormones release triglycerides for energy between meals.

D. To store energy
The main function of triglycerides is to store unused calories/energy to use later, so I believe it is D.

Answer:

In cystic fibrosis, there is an alteration in the chlorine channels of all cells, so all kinds of body secretions are affected.

Body fluids thicken at the intestinal level, forming a mucus that blocks the ducts that carry digestive enzymes from the pancreas to the intestine.

If 30% of the bases in a particular DNA molecule are guanine (G), what percentage of the bases would be thymine (T)? Explain your reasoning.

Answers

Answer:

20%

Explanation:

There are four bases in DNA: guanine (G), cytosine (C), adenine (A), and thymine (T). They all have to add up to 100%. In DNA, guanine pairs with cytosine and adenine pairs with thymine.

If guanine is 30%, cytosine is also 30%.

30% + 30% = 60%

Now subtract from 100%.

100% - 60% = 40%

Thymine and Adenine make up 40% of the DNA. Now divide by 2 since there are two nitrogenous bases.

40% ÷ 2 = 20%

Guanine is 30%, Cytosine is 30%, Adenine is 20%, and Thymine is 20% for a total of 100% of the DNA.

After surgical removal of the spleen (i.e., a splenectomy), some other organs take over most of its functions. Which of the following spleen functions in the adult can not be performed by bone marrow?
A) immune surveillance
B) erythropoiesis
C) removal of aged and damaged red blood cells from the blood
D) storage of platelets

Answers

Answer:

removal of aged and damaged red blood cells from the blood

Explanation:

Spleen is an organ found in vertebrates and it is located in the upper part of the abdomen that act majorly to filter blood. It recognizes and removes old, malformed, or damaged and aged red blood cells. When blood flows into the spleen, the spleen performs "quality control"; the red blood cells must pass through a maze of narrow passages.

The bone marrow is a spongy tissue that produced red blood cells and this perform similar function as the spleen except that it cannot remove aged and damaged red blood cells from the blood this is because it does not have the ability to remove age and damage red blood cells due to inability to support the immune system.

The spleen help remove age and damage red blood cells thereby boosting the immune system in fighting against infections ,preventing blood clot .

Answers

Answer:

This is because the virus has been found in the semen longer than other body fluids.it has been found in infected semen for 180 days after healing.

In infected pregnant women,this can be transmitted to the fetus,causing microcephaly in the unborn child,Protection against mosquito bites is best way of prevention.

SUBMIT

Answers

Answer:

C. Respiration can happen without sunlight, but photosynthesis

cannot.

Explanation:

Respiration is the metabolic process by which the cells of living organisms, plants inclusive, obtain energy. Photosynthesis, on the other hand, is the process whereby plant cells synthesize their food in form of sugars (glucose).

Photosynthesis takes place in two stages namely: light dependent stage and light independent stage. The light dependent stage occurs strictly in the presence of sunlight, where oxygen gas is released as a product. Hence, it can only occurs during the day. Respiration, which breaks down the sugar product of photosynthesis to produce energy, occurs at anytime (day or night). Carbon dioxide (CO2) gas is released as a product.

Since the light dependent stage of photosynthesis cannot occur without sunlight, it cannot occur at night. this means that oxygen gas will not be released at night. However, respiration which occurs during daytime and nighttime continually releases carbon dioxide gas. This accounts for the reason CO2 gas is produced more by plants than oxygen at night.

Mules are considered to have many superior characteristics compared to the horse or burro. Mules are often stronger, agile, and can jump higher than either of their parents. Why are mules considered to be a weak hybrid and not a separate species?

Answers

Answer:

Because they are sterile

Explanation:

Mules are considered to be a weak hybrid and not a separate species because they are sterile and cannot produce progeny of their own.

Mules are hybrid products from two separate species - a donkey and a horse.

A species is generally defined as a group of organisms that are capable of breeding to produce fertile offspring. Hence, in order for them to have the potential of being categorized as a separate species, they must be able to produce their own progeny but this is not the case.

Answer:

1. merkel cells

2. tactile corpuscle

3. lamellated (lamellar) corpuscle

4. nociceptors

Explanation:

Merkel cells are epithelial cells found around hair follicles which are capable of sensing gentle touch sensations such as, for example, tactile discrimination and environmental exploration. Tactile corpuscles are a class of nerve ending required for mediating sensitivity to light touch sensations. The lamellar corpuscles are another class of nerve ending capable of sensing deep touch sensations and vibrations. Finally, nociceptors are somatic sensory receptors capable of sensing noxious (damaging) stimuli.

1. Light-touch receptor located at the epidermal-dermal border: Tactile corpuscles (D)

Light-touch sensors called tactile corpuscles, sometimes referred to as Meissner's corpuscles, are situated near the epidermal-dermal boundary. They are located in the papillary layer of the dermis's dermal papillae, which are tiny, finger-like projections.

Particularly dense populations of tactile corpuscles can be seen in skin regions like the lips, palms, and fingertips that are sensitive to gentle touch.

2. Light-pressure receptor located in the papillary layer of the dermis: Merkel cells (A)
