Which of the following has the greatest effect on the protein molecule produced
by a ribosome?*
A. The sugars in the RNA molecule
B. The nitrogenous bases in DNA
C. The hydrogen bonds in the tRNA
D. The phospholipids in the cell membrane
Answer:
The answer is B.
Explanation:
Depending on what order the nitrogen bases are used in the DNA will determine the opposite bases placed on the RNA making the sequence different, making the protein different.
The nitrogenous bases in DNA has the greatest effect on the protein molecule produced by a ribosome. Thus, option B is correct.
What are the nitrogenous bases in mRNA?Nitrogenous bases in mRNA are the sequence of amino acids. The translation is one of the two-stage events in protein synthesis. Protein synthesis is the process in which protein or polypeptide chains are synthesized by the DNA. This is the use of nitrogenous bases in mRNA.
The process of translation is similar to a smartphone app converts spoken English into Spanish as it involves the translation of the sequence of nitrogenous bases in mRNA molecules to the polypeptide or sequence of the amino acids.
Protein has been defined as the large macromolecules and biomolecules that are made up of long chains of amino acid. There has various function of protein such as DNA replication, speeding up chemical reaction, and helps to maintain the structure of cell.
Therefore, The nitrogenous bases in DNA has the greatest effect on the protein molecule produced by a ribosome. Thus, option B is correct.

what is the dominant impact that humans have on alpine glaciers?
The researchers estimate that between 1990 and 2010, some 69 percent of the mass lost by the world's alpine glaciers can be traced to human influence – basically global warming. This 2013 file photo shows the Mendenhall Glaicer where it spills over the mountains above Mendenhall Lake in Juneau, Alaska.
Answer:
Human activity is playing an increasing role in the melting of glaciers, Austrian and Canadian scientists have found. One of the most disruptive effects of climate change, glacier retreat leads to rising sea levels, landslides and unpredictable availability of water downstream.

How is water split into hydrogen and oxygen during photosynthesis?
Explanation:
The chlorophyll's donated electrons need to be replaced, and these electrons come from the splitting of water. In a process called photolysis ('light' and 'split'), light energy and catalyst s interact to drive the splitting of water molecules into protons (H+), electrons, and oxygen gas.

If the environment gets cold, humans will often respond involuntarily by shivering in order to:
a. keep body temperature the same as the external temperature
b. increase body temperature
C. decrease body temperature
d. regulate blood pressure
Answer:
increases body temperature
Explanation:
this is because when you shiver your blood vessels contract which then increases your body temperature
If the environment gets cold, humans will often respond involuntarily by shivering in order to increase body temperature. So, the correct option is B.
What do you mean by Environment?An environment may be defined as anything that is present in the surroundings of living entities that is either biotic or abiotic.
The process of shivering causes the blood vessels to contract and relax at a rapid rate to maintain homeostasis. The signals of rapid contractions are sent by the hypothalamus through nerve impulses.
Therefore, the correct option for this question is B.

Albinism is a recessive trait where an individual does not produce the pigment melanin. A man and woman both produce melanin, but both have one parent with albinism. What is the probability that their first child will have albinism
Answer:
The child has a 1/4 chance of having albinism
Explanation:
I hope this helps!
For most types of OCA, both parents must carry an albinism gene to have a child with albinism. Parents may have normal pigmentation but still, carry the gene. When both parents carry the gene, and neither parent has albinism, there is a 25% chance at each pregnancy that the baby will be born with albinism.
What is the probability that their first child will have albinism?
This means a child has to get 2 copies of the gene that causes albinism (1 from each parent) to have the condition. If both parents carry the gene, there's a 1 in 4 chance that their child will have albinism and a 1 in 2 chance that their child will be a carrier.
Do both parents have to carry the albinism gene?
Yes, albinism is passed down (inherited) through families. People are born with albinism when they inherit an albinism gene from their parents. In albinism, both parents must carry an albinism gene for their child to be born with albinism.

Seawater has many different gases dissolved in it, specially nitrogen, carbon dioxide and oxygen. It exchanges these gases with the atmosphere to keep a balance between the ocean and the atmosphere.
What is atmosphere?An atmosphere is defined as the layers of gases surrounding a planet or other celestial body. Earth's atmosphere is comprises of about 78% nitrogen, 21% oxygen, and 1% other gases.
Dissolved oxygen and carbon dioxide are important for marine life. Marine plants use dissolved carbon dioxide, sunlight and water to make carbohydrates through the process of photosynthesis.

regulation of the cell cycle is dependent on cyclins and cyclin-dependent kinases. the key that allows a cell to progress beyond the restriction point is
The key that allows a cell to progress beyond the restriction point is the phosphorylation of specific proteins (for example RB) by Cdk. The cyclin-dependent kinases (CDKs) are able to phosphorylate different substrates.
Cyclins regulate the progression of the cell cycle by their interaction with cyclin-dependent kinases (Cdks).
This binding activates the Cdks, thereby converting them into functional enzymes that phosphorylate target proteins and thus regulate cell cycle progression by bypassing restriction points of the cell cycle.
CDKs can phosphorylate different substrates by transferring phosphate groups from adenosine triphosphate (ATP) to specific amino acidic residues in these substrates.
For example, CDKs phosphorylate Rb proteins and thus regulate their activity during the cell cycle.

The primary purpose of the ______ circuit is for the blood to release carbon dioxide and pick up oxygen.
Answer:
Explanation:
The primary purpose of the systemic circuit is for blood to release carbon dioxide and pick up oxygen
The primary purpose of the pulmonary circuit is for the blood to release carbon dioxide and pick up oxygen.
What is pulmonary system?It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs.
Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.
The respiratory system makes it possible for the body to take in oxygen and expel carbon dioxide.
The nose and mouth are the beginning of the respiratory system, which continues through the airways and lungs.
The pulmonary circulation serves a variety of crucial purposes. Its main job is to exchange gases across the alveolar membrane.
This ultimately results in oxygenated blood being delivered to the rest of the body and carbon dioxide being removed from the bloodstream.
Thus, the pulmonary circuit's main function is to allow the blood to absorb oxygen and release carbon dioxide.

Why can't humans regrow limbs?
Answer:In fact, most of our organs have some turnover in cells, which explains why they're younger than our biological age. The human heart, skin, intestines, and even our bones are slowly replaced over time, meaning that a limited amount of damage can be reduced. However, this doesn't extend to limbs.

so please don't mindHow many minutes are there in a 40-hour week?
A:2,000
B:2,400
C:1,400
D:1,200
There will be 2,400 minutes in a week of 40 hours. This can be calculated by the help of unit conversion of time. Thus, the correct option is B.
What is Unit conversion?
Unit conversion is the change of one form of unit to another form of unit of different system such as conversion of units of measurement of weight from gram to kilogram or milligram.
Unit conversion of one unit to another unit is used in order to have accuracy and avoiding the confusion in measurements. For example, the length of pencil is not measured in kilometers rather it is measured in centimeters or inches, which are comparatively smaller than kilometers. In such a case, one has to convert the unit of length from kilometer (km) to centimeter (cm).
The week of 40 hours can be converted into minutes by:
Number of minutes in 1 hour = 60
Therefore, the number of minutes in 40 hours = 60 × 40 = 2,400 minutes
Therefore, the correct option is B.
