20. You have a segment of DNA that contains 26% Adenine, what percent of Cytosine will there be?
a. 24%
b. 26%
c. 52%
d. 48%
Answer:
A
Explanation:
as all bases will be 100% so there will be same about of adenine and thymine so 26+26 =52 do 100-52=48 which will be the amount of cytosine and guanine so 48÷2=24 which will be the amount of cytosine.
hope this make sense :)

calculate the solute potential of a 1.0 M sucrose solution at 25 C and standard atmospheric conditions
The solute potential will be "-24.4658 liter-atm".
Given values are:
Concentration,
C = 1.0 MTemperature (in Kelvin),
T = 25+273= 298
Ionization constant,
i = 1Universal gas constant,
R = 0.0821 \ liter-atm/mol-KThe solute potential will be:
→ [tex]\psi_s = -iCRT[/tex]
By substituting the given values, we get
→ [tex]= -(1\times 1\times 0.0821\times 298)[/tex]
→ [tex]= - 24.4658 \ liter-atm[/tex]
Thus the above solution is correct.

how many molecules are in 2fe203
Answer:
2 molecules.
Explanation:
In 2Fe203, there are two molecules because Fe203 is a molecule which is made up of two atoms i.e. iron and oxygen atom. In one molecules of Fe203, there are 5 atoms so in 2 molecules of Fe203, there are 10 atoms. The digit present in front or to the left side shows number of molecules so that's why we can say that there are only two molecules in 2Fe203. The name of this molecule is iron oxide.
Which of the following is NOT part of the first line in immune defense? *
Mucus
Sweat
Tears
Antibodies
Skin
Answer:
Antibodies
Explanation:
Skin, tears, sweat and mucus, are all first line of defense.
The part that is not the first line of immune defense is antibodies. The correct option is d.
What are antibodies?
The immune system is a bodily system that consists of white blood cells and antibodies that aid in the fight against any external invaders or infections that enter the body.
They are the body's defense mechanism. Antibodies recognize the pathogen and assist your body in combating it. These antibodies are produced by your body's immunological system. Everyone possesses a variety of antibodies. Each of them detects intruders, such as viruses and bacteria, that might cause illness.
An antibody is a protein that the body's immune system produces when it recognizes dangerous chemicals known as antigens. Microorganisms (bacteria, fungi, parasites, and viruses) and chemicals are examples of antigens.
Therefore, the correct option is d, Antibodies.

How do both species benefit in this relationship? (Crocodile & Plover)
A. The Crocodile gets a home and the Plover gets protection
B. The Crocodile gets its teeth cleaned and the Plover gets food
C. The Crocodile gets protection and the Plover gets food
D. Crocodile gets food and the Plover gets cleaned
Answer:
B.
Explanation:
Egyptian plovers and crocodiles have a unique symbiotic relationship. Crocodiles can’t use dental floss, they get food stuck in their teeth. All that food rots their teeth and probably causes some pain. When a crocodile feels the need for a good tooth cleaning it will sit with its mouth wide open. The Egyptian plover bird sees the invitation, and if one is nearby it will fly into the mouth of the crocodile, eat the food stuck in its teeth, and fly away unharmed.

C. ATP
b. glucose
d. ADP
The energy that cells need for cellular processes is found in the chemical bonds that make up ATP (adenosine triphosphate).
What is ATP?ATP, or adenosine triphosphate, is a molecule that stores and provides energy for cellular processes. It is often referred to as the "energy currency" of the cell. ATP is composed of three phosphate groups, a sugar molecule (ribose), and a nitrogen-containing base (adenine).
The energy stored in the bonds between the phosphate groups is released when the last phosphate bond is broken, forming ADP (adenosine diphosphate) and a free phosphate group. This process, called hydrolysis, releases energy that is used by the cell to drive metabolic processes such as muscle contraction, nerve impulse transmission, and protein synthesis.
ATP is produced in the mitochondria through cellular respiration and is constantly recycled within the cell to provide energy for ongoing cellular processes.

Why is the reduction in chromosomes number important in meiosis?
Explanation:
Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.

all plant bodies(root,stem and leaf) are externally covered by epidermis but why woody plant is covered by barks
Answer:
Bark comprises all the tissues surrounding the xylem in woody plants. Broadly, bark includes an inner and mostly living region and an outer, dead one. Of all plant structures, bark has the most complex anatomical structure and ontogenetic origin involving two (and often three) different meristems.
As to why, the bark adds layers to the inside ring of the vascular cambium, the outside is pushed outward. The cells die off, and the fibrous matrix of cellulose and lignin molecules remain. This hard structure forms the bark, and protects the tree or plant from many forms of damage.
