Which of the following events happens first in the development of a new organism?a. A morula is formed.
b. A blastocyst implants into the uterine wall.
c. A sperm fertilizes an egg to form a zygote.
d. A zygote undergoes mitosis.

Answers

Answer 1

Answer: The answer is c. A sperm fertilizes an egg to form a zygote.

The first step in the development of a new organism is a sperm fusion with an egg and formation of a zygote. The zygote then undergoes mitotic divisions and as a result a morula forms. Morula is 16-cell mass that continues to divide and forms a blastocyst, which later implants into the uterine wall.

The _________ channels the waste-filled blood to the excretory system.a. Small intestine
b. Renal Artery
c. Ureter

Answers

It is the Renal Artery that channels the is waste-filled blood the excretory system. Main function of renal artery is to carry blood from the heart to the kidney. It starts from the heart and carries a volume of blood to the kidney to be filtered.

The main organs of the excretory system are the kidneys. Waste-filled blood is routed to the kidneys via the renal artery. The kidneys then filter the blood, removing excess water, salts, uric acid, and chemicals from medications or poisonous substances.

A bowler getting strike during a particular frame has an estimated probability of 41%. If several simulations of the bowler bowling 2 frames were performed, what percentage of the simulations would the bowler be most likely to get a strike in each of the two frames?A. 61%
B. 38%
C. 18%
D. 81%

Answers

The percentage of simulations that the bowler would most likely get a strike in each of the two frames would be 18%. The correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that has actually come to your great help.

Answer:

Option C

Explanation:

Given -

The probability of a bowler getting a strike during a particular frame $= 41$ % $= 0.41\n$

Solution:

Probability of a bowler getting a strike during a particular frame is independent of frames.

Thus,

Probability of a bowler getting a strike during a single frame $= 41$ % $= 0.41\n$

Probability of a bowler getting a strike during a double frame

$= ((41)/(100) )^2\n= (0.41)^2\n= 0.41 * 0.41\n= 0.1681\n$

≈ $18%\n$ %

Which element is found in nucleic acids but not in proteins?

Answers

Phosphorus is the element found in nucleic acids but not in proteins.

Further Explanation

Proteins

Proteins are one of the major biomolecules that exists in nature.
They are made of amino acids which are the building blocks. Amino acids contain four different elements which include;

Hydrogen
Oxygen
Nitrogen
Carbon
Some amino acid contains sulfur element.

Nucleic acids

Nucleic acids are one of the four major bio-molecules in nature. Nuclei acids is divided into two; RNA and DNA.
The building blocks of nucleic acids are Nucleotide bases which are made by a nitrogenous base, a sugar and a phosphate group.

DNA

DNA is a nuclei acid that is responsible for carrying genetic information in living organisms.
It is through DNA that genetic information is passed from one organism to another through the process of DNA replication.
Additionally, it carries the information that is used to make proteins which performs various functions in living cells.
Each Nucleotide in DNA contains a nitrogenous base, a deoxyribose sugar, and a phosphate group.
DNA molecules are made up of nitrogenous bases; Adenine, Guanine, Cytosine and Thymine.

RNA

Ribonucleic acid (RNA) is a type of nucleic acid, a molecule that plays a major role in the flow of information from the DNA to the proteins. For a gene to be expressed information has to be passed through the RNA.
Each nucleotide in RNA contains a nitrogenous base, a ribose sugar, and a phosphate group.
Nitrogenous bases in RNA includes; Adenine, Guanine, Cytosine and uracil. Thymine in DNA is replaced with Uracil.

Keywords: DNA, RNA, Nitrogenous bases

The element is found in nucleic acids but not in proteins are the Phosphorous.

Nucleic acids are polynucleotides, which are long chainlike polymers made up of essentially identical nucleotide building components. Each nucleotide is made up of a nitrogen-containing aromatic base that is linked to a pentose (five-carbon) sugar, which is then linked to a phosphate group.

Proteins are composed of hundreds or thousands of smaller units known as amino acids that are linked together in lengthy chains. A protein is made up of 20 different types of amino acids that can be mixed. The sequence of amino acids determines each protein's distinct three-dimensional structure and function.

Thus, Phosphorous is the element which is found in nucleic acid but not in proteins.
