Which type of muscle tissue has cylindrical cell with multiplie nuclei striated muscle and voluntary regulation?

Proteins are polymers. <br> a. True<br> b. False

xz_007 [3.2K]

False

Proteins are polymers of molecules called amino acids, some contain thousands. Lipids are formed when a glycerol molecule combines with compounds called fatty acids, therefore they are not polymers because they contain one molecule and are not macromolecules. Hope this helps! :)

Use the numbers 1, 2, 3, 4, and 5 to place the protein creation steps below in the correct order. Ribosome attaches to the mRNA.

kirza4 [7]

Answer: The correct sequence for the protein creation is as follows-

1) Information is transcribed in DNA to mRNA.

2) mRNA leaves the nucleus.

3) Ribosome attaches to the mRNA.

4) tRNA anticodon carries an amino acid that compliments the mRNA codon.

5) The chain of amino acids forms a protein.

According to the Central Dogma, the genetic information is transferred from DNA to mRNA to Proteins.

The first step is transcription in which DNA is converted to mRNA with the help of enzyme RNA polymerase. In eukaryotic cells, this process occurs in the nucleus.

This is followed by translation, which takes place in the cytoplasm when mRNA leaves the nucleus.

Ribosomes are the specialized organelles, which act as the site for protein synthesis ( translation).

Ribosomes attach to the mRNA. tRNA brings amino acid, which has anticodon complementary to the codon present in the mRNA. A chain of amino acids is thus synthesized, which is called Protein.

An experiment is done on 90 people to test their vitamin D levels: 30 are given vitamin D tablets, 30 are told to spend 15 minut

Jet001 [13]

Answer:

The correct answer is -

The control group: the group of people with no supplements and kept inside.

The dependent variable: Vitamin D level in all groups.

The independent variable: the source of vitamin D (sun or tablets)

Explanation:

The control group of any experiment is the group of subjects that did not receive any type of treatment or did not manipulate by the independent variable. Here the group of 30 people that kept inside and did not get supplements is the control group.

The independent variable is a variable that directly affects the dependent variable by a change in the independent variable. In this experiment, the sunlight and vitamin D tablets are independent variables that affect the vitamin D level in people.

The dependent variable is a variable that is affected by the independent variable or depends on the independent variable, vitamin level is the dependent variable.

A zygote is formed from the fusion of a sperm and an egg. The zygote undergoes cell division during embryonic development. After

OleMash [197]

After four divisions, the zygote becomes a morula- the stadium that consists of 16 blastomeres. By the fifth day of development the form of the blastocyst is formed through the processes of compaction, cell division, and blastulation. Later, specialized cells in the embryo are derived from the inner cell mass (ICM) of the blastocyst.
