Answer:
Dogs are wonderful human companions. They are the first species that humans domesticated and they have a long history of close relationships with people.
If you spend any time with dogs (I have two wonderful adopted dogs who shower me with affection and fur), then you see first-hand the many ways that dogs can respond to their owners. A dog may treat a stranger with suspicion, but dances with joy when its owner returns. Indeed, when one of our grown children returns after a long absence, the dogs respond with excitement.
Question: Which of the following objects might orbit a planet?
A. a moon B. an asteroid C. a galaxy D. a star
Answer:
"Moon" that orbit a planet.
Explanation:
Moon has made its orbit around the Earth that we live, But the asteroid and the stars given in the option revolve around the sun. And the place where we live is the galaxy. Moon has made its orbit around the earth and also is natural satellite. Among all it is the fifth largest in the count of the largest satellite present in our solar system. It is also referred as the largest planetary satellite which is when compared with the size of the planet.
DNA in prokaryotes frees in the cytoplasm, while in eukaryotes (like humans) DNA is in the nucleus.
Human DNA is found in the cells that make up your tissues and organs: nerve cells, liver cells (liver), skin cells ... They are extremely numerous, more than 50 000 billion and have very diversified functions! Most of our cells are microscopic (20 to 30 micrometers) and contain an even smaller nucleus structure.
Each nucleus contains the genetic material of the cell, the chromosomes.
Mitochondrial DNA can also be found in mitochondria, but mitochondria are much smaller than nuclear DNA.
Answer:
the correct answer is c i just tuck the text
Explanation:
Answer:
- ATP and NADPH facilitate the reduction of 6 molecules of 3-PGA (formed in carbon fixation)to six molecules of the simple sugar glyceraldehyde 3-phosphate (G3P).
- In the reduction process ADP and NADPH+ are made, when ATP releases energy and loses its terminal phosphate, and NADPH loses energy and a hydrogen atom.
- ADP and NADPH+ return to the light-dependent reactions for re-use.
Explanation:
Sugar biosynthesis in plants, called photosynthesis produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. In chloroplasts, this occurs in the light-dependent and dark reactions. In the light- dependent reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.
In the light-independent reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP). Organic molecules are reduced and RuBP is regenerated.
