A student is investigating the effect of concentration of acid on the

Biology
1 answer:
bearhunter [10]2 years ago
5 0

Answer:

See the answer below

Explanation:

<em>Increasing the concentration of the acid means that the number of ions/particles in the reaction vessel has increased. The higher the number of ions/particles, the higher the frequency of collision of these ions provided that the volume of the reactants remains unchanged. </em>

It is just like comparing a densely populated area with a sparsely populated area. You are more likely to encounter people at a higher frequency in a densely populated area when compared to a sparsely populated area.

(a)The same kind of plants grown &amp; cultivated on a large scale at a place is called_____ (b) The first step before growing c
valkas [14]

Answer:

Following the answers are given below:-

Explanation:

(a) Plants of the same type that are grown and grown at a large-scale spot are referred to as crops. They are mostly cultivated for useful products.

(b) The very first step in the growth of plants is soil time to prepare to easy way to help water infiltration, appropriate oxygenation, and soil microbial economic expansion. Soil program includes the softening and attempting to turn of plant roots through all the plow procedure. The next step in growing crops is the collection of safe crops that is performed for some time by placing the seed in a water-filled flask.

(c) Infected seeds are lighter and hollow in strength and therefore rise at the top of the atmosphere. The good seeds calm down a bit at the edges, becoming heavier, which is used for sowing.

(d) Sunlight, water, and nutrients are essential requirements for seed germination and seedling growth. Seed seeding to the right depth and adequate spacing among seeds and seedlings confirm that these criteria are fulfilled.

(e) The principal Kharif crops in India are corn, maize, and cotton.

(f) individuals are used for producing plant manure.

(g) A combination of calcium acid phosphate and calcium sulfate formed by processing sulfuric phosphate stone: used primarily as a phosphate.

(h) Vegetables and lean meats are the two major categories of commercial grain crops. The word applies primarily to seeds from family Fabaceae plants, such as wheat, corn, and rice; seeds of non-edible vegetation types are often referred to as "grains."

Why is water essential to life on a chemical level?
babymother [125]
Well Water is essential to life for a number of reasons. It is a useful solvent that exists as a liquid at the ideal range of temperatures for life as we know it on Earth, behaving as a perfect medium across which biochemical reactions can occur. Your cells transport resources across the spaces within and between them facilitated by this medium, just as your blood serves as the ideal medium for transporting oxygen-carrying corpuscles and a rich soup of nutrients, hormones, and even waste products being sent for filtration. The very structure of your tissues is reliant upon water content; consider the difference between a fresh loaf of bread and a stale (dry)one that can be crumbled between the fingers. Plant cells, just like animals cells, require hydration to function, too. In fact, right down to unicellular life forms, life as we know it on this planet relies upon water existing as a liquid in order to function on a <span>biochemical level. I hope that helps you.</span>

All of the following protect the skin and mucous membranes from infection except
leva [86]

The question is incomplete. Th ecomplete question is as following:

All of the following protect the skin and mucous membranes from infection EXCEPT  

A) multiple layers of cells.

B) tears.

C) saliva.

D) HCl.

E) the "ciliary escalator."

Answer: D) HCl.

Explanation:

  • The epidermis, the outer layer of the skin provides waterproofing and serves as a barrier to infection and other laers also sustain any type of injury.  
  • Tears wash out foreign bodies which enter the eye. In addition, tears contain a substance called lysozyme which has an antibacterial function and works to prevent microbial invasion and infection.  
  • Saliva protects against infection, especially via the innate immune system. This mechanism is an important first-line protection against bacterial and viral infection
  • The mucociliar escalator is within the conducting airways and is composed of mucus and cilia that transfer the mucus up and out of the lungs where it can be removed by coughing or swallowing,

Whereas HCL helps in the digestion process.

Hence, the correct option is D.
