When Mendel conducted his pea plant genetic experiments, he found that the first generation (F1) of offspring were all true purple plants, but the second generation (F2) contained some white flowers. How did this refute another theory of inheritance based on the idea that traits in offspring were an equal mix of the traits of their parents?

Answers

Low precision and low accuracy best describe the archer's results. So the correct option is A.

Who is an archer?

Archery is a sport that involves firing arrows with a bow at inanimate objects or animals during a hunt.

With the exception of Australia, the bow has been a primary tool of combat and the hunt from prehistoric times.

Ancient Egyptians and Greeks also engaged in recreational archery in addition to military archery, an example of the latter being the contest in which Odysseus triumphed and gained Penelope's hand.

Large portions of Asia were ruled by horse-mounted archers such as the Huns, Seljuq Turks, Mongols, and others for around 15 centuries beginning in the first century CE.

During the Hundred Years' War (1337–1453), English longbowmen earned magnificent military successes, while the crossbow gained popularity throughout continental Europe, particularly in Switzerland, some regions of Germany, France, and the Low Countries.

Therefore the correct option is A.

What are centrioles and centrosomes?​

Answers

Answer:

What are centrioles and centrosome?

Within the cell, a centrosome is a structure that organizes microtubules during cell division. Each centrosome contains “paired barrel-shaped organelles” called centrioles and a “cloud” of proteins referred to as the pericentriolar material, or PCM. They also enable movement of other organelles within the cytoplasm

Explanation:

Answer:

a centrosome is a structure that organizes microtubules during cell division. Each centrosome contains “paired barrel-shaped organelles” called centrioles and a “cloud” of proteins referred to as the pericentriolar material, or PCM.

Centrioles are made up of short lengths of microtubules “arranged around a central cavity.” Each centriole is around 500 nm long and 200 nm in diameter. The function of centrioles in animal cells is to organize the PCM to aid in microtubule formation.

nucleic acids are assembled in the _____ direction.

Answers

5’ to 3’ hope this helps:)

Nucleic acids are assembled in the 5' to 3' direction during DNA replication. DNA replication is the process of duplication of DNA molecule.

What are Nucleic acids?

Nucleic acids are the biomolecules occurring in the chemical compounds which serve as the primary information-carrying molecules in the cells. Nucleic acids play an important role in directing the process of protein synthesis. The two main classes of nucleic acids include deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Nucleic acids can only be synthesized in vivo in the 5′-to-3′ direction and these can be assembled in the same direction in cell, as the polymerases which assemble various types of new strands generally rely on the energy which is produced through breaking the nucleoside triphosphate bonds to attach these new nucleoside monophosphates to the 3′-hydroxyl (−OH) group, through a phosphodiester bond.

Which molecule supplies chlorophyll with electrons

What happens during photosynthesis?

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose (sugar) and other carbohydrates. This process also produces oxygen as a byproduct.

During the process of photosynthesis, chlorophyll absorbs light energy, which is used to split water molecules into oxygen and hydrogen atoms. The hydrogen atoms are then used to generate ATP and NADPH, which are used to power the process of carbon fixation. The oxygen atoms are released as a byproduct of water splitting and become a part of the oxygen in the Earth's atmosphere.
