Answer 1

Answer:

Answer: A common ancestor

Explanation: Homologous structures in different species could suggest that they shared a common ancestor.

O Oxygen is made from the breakdown of carbon dioxide during photosynthesis.
O Energy is absorbed by chlorophyll during photosynthesis.
The sun gives off light energy that is absorbed by plants.

Answers

Answer:

Light energy is converted to chemical energy during photosynthesis.

Explanation:

The first law of thermodynamics, which is the LAW OF CONSERVATION OF ENERGY, states that energy can neither be created nor destroyed but can only be changed from one form to another. This law explains that the energy that exists cannot be made or destroyed, it can only be transformed from one of Its form to another.

The biological process of photosynthesis illustrates this law. Photosynthesis is the synthesis of organic molecules from inorganic molecules using the energy from sunlight. Plants, via their Chlorophyll pigment capture the light energy from the sun and use it to produce their food in form of organic molecules/glucose. This glucose is a chemical compound that stores energy in its chemical bonds.

Hence, photosynthesis supports the law of conservation of energy by changing/converting light energy from sun into a chemical energy in food (glucose).

Astronauts and scientists conduct research studies aboard the International Space Station in a satellite that was built by_____.A. the United Nations.
B. the United States.
C. twenty nations.
D. sixteen nations

Answers

I think the correct answer from the choices listed above is option D. Astronauts and scientists conduct research studies aboard the International Space Station in a satellite that was built by sixteen nations. Hope this answers the question. Have a nice day.

D. sixteen nations

The International Space Station (ISS) is the biggest space station ever constructed, the largest structure ever congregated in space, and one of the most complicated global experimental projects in history.

The United States, with the help of NASA, commences the ISS project, by involving 15 other nations in construction and operating several parts of the station. The nations involved are Russia, Canada, Japan, Brazil, and 11 member countries of ESA (Belgium, The Netherlands, Norway, Spain, Sweden, Denmark, France, Germany, Italy, Switzerland, and the United Kingdom.

Which statement is a reason for the peer review process in scientific research?to make scientific research progress more quickly

to verify that the conclusions that are made are supported by the data

to allow anyone to submit their research to scientific journals

to ensure that only established tools and techniques are used

Answers

The correct answer is the second choice - peer review process in scientific research exists in order to verify that the conclusions that are made are supported by the data. You cannot make a valid conclusion if you do not have enough evidence or data to prove it - this is why your peers have to go through your research to make sure everything is done according to the rules of scientific research.

Scientists have recently modified the bacteria that cause tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid. What is the new DNA called?.

Answers

Scientists have recently modified the bacteria that causes tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid. The new DNA is called recombinant DNA.

What is DNA?

DNA is defined as deoxyribonuclic acid and it is a polymer made up of two polynucleotide chains that arranged in foiled structure to form a double helix carrying genetic information for the various processes such as growth development functioning and reproduction.

There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.

Friedrich miescher discovered DNA in the year of 1860.Scientists have recently modified the bacteria that causes tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid. The new DNA is called recombinant DNA.

The main function of DNA is to carry information from one generation to another generation this is the reason due to which DNA is also known information molecule.

In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA.

The shape of DNA is double helical structure.Scientists have recently modified the bacteria that causes tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid. The new DNA is called recombinant DNA.

Siblings share only about 50% of same DNA due to the reason of recombination.

The life span of DNA is 521 years.There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.

CANT GET WRONG , ITS LIKE A WORK BANK BUT DONT KNOW WHAT ITS CALLED.In any family, the children may or may not look like their parents. They may or may not look like their siblings. That's because each one of us inherit half of our chromosomes from our mother and half from our father. What assortment of we get varies from child to child. Our chromosomes contain many genes, and each gene codes for a specific trait. The traits people see, like eye color hair color, or height, also depend on whether the gene is dominant or recessive. In this family, brown hair is dominant over red hair. It is very possible that these two parents could only have children with brown hair! It is also possible that their children all have red hair! Why? First, to inherit a recessive trait like red hair, you must have two genes for red hair color. Because one parent, the mother, has red hair we know the mother must have two genes for red hair. The father has brown hair. We know he must have at least one gene for brown hair but he also has one gene for red hair. What two genes will their children have? It's a matter of probability. Each child has a 100% chance of inheriting the red hair gene from their mother and a 50% chance of inheriting the red hair gene from dad. That means, all the children will have at least one gene for red hair!

1.Where do our chromosomes come from? (Twelve word phrase)
2.What codes for each specific trait? (One word)
3.In this family, what is the dominant hair color? (Two words)
4.In this family, each child has a _______ chance of inheriting one gene for red hair. (Percentage)
5.What combination of genes you receive from your parents is a matter of ______________. (One word)

Answers

1.half of our chromosomes from our mother and half from our father
