What purpose does a female pine cone serve?
A.
It protects the seed until it matures.
B.
It makes food for the adult plant.
C.
It allows for photosynthesis to occur.
D.
It acts as an object to attract birds.
E.
It serves as an ornamental object on the tree
Answer:
It protects the seed until it matures
Explanation:
Pine cones don't have chroloplasts so they can't produce photosynthesis. Pine cones are rough and spiky and birds wouldn't want to put something rough and spiky in their nests where they raise their young. But it is rough and spiky enough to protect the seed until it's been dispered far enough to break open the shell and start growing.
Answer:
A.
It protects the seed until it matures.

Relaciona cada acontecimiento del ciclo cardíaco con alguno de estos términos diástole, sístole auricular o sistole ventricular
Answer:
El ciclo cardíaco consta de dos períodos i. mi. diástole y sístole.
Explicación:
El ciclo cardíaco consta de dos períodos i. mi. La diástole es aquella durante la cual el músculo cardíaco se relaja y se llena de sangre, mientras que la sístole es un período de contracción y bombeo de sangre. La diástole ventricular es el momento en el que las dos cámaras inferiores del corazón conocidas como ventrículos se relajan para permitir que la sangre fluya hacia adentro. La diástole auricular es el momento en que las dos cámaras superiores del corazón llamadas aurículas se relajan y permiten que la sangre fluya en.

why is the mesosphere the coldest layer in the atmosphere?
Answer:
As you go higher in the mesosphere, the air gets colder. The air is much thinner (less dense) in the mesosphere than in the stratosphere below. There are fewer air molecules to absorb incoming electromagnetic radiation from the Sun. ... Carbon dioxide in the mesosphere also helps make this layer cold.
Answer:
the air is much thinner (leas dense)
Explanation:
as u go higher in thw mesosphere the air gets colder in the mesosphere than in the stratosphere
what is the mRNA ? how do you read this ?
Answer:
The acronym mRNA means messenger ribonucleic acid, the nucleic acid responsible for transporting genetic information to the ribosome so that protein synthesis can occur.
Explanation:
Messenger ribonucleic acid or mRNA, is a nucleic acid responsible for containing the genetic code, organizing it into codons —depending on the specific sequence of nitrogenous bases— and taking it to the ribosome for translation and initiation of protein synthesis.
A codon is a sequence of three mRNA nucleotides, each of which encodes a specific amino acid, in addition to:
Marking the start of protein synthesis, by means of the UAC start codon, which also encodes for amino acid methionine (MET). Indicate the stop of protein synthesis, by means of the STOP codons —UAA, UAG and UGA— which do not code for amino acids.This can be seen in the table:
The first line is the sequence of nitrogenous bases of one of the DNA strands. The second line should indicate the sequence of complementary bases of the other DNA strand, which will be transcribed. However, the presence of uracil indicates that it is the mRNA transcribed The third line is the sequence of nitrogenous bases in the mRNA strand, organized in triplets or codons. The fourth line expresses each of the amino acids and instructions found in the mRNA fragment that was transcribed methionine (start), lysine, tryptophan, proline and STOP (although GUU encodes the amino acid valine and is not a STOP codon).Millipedes are.

how are electrons carried fro glycolysis and the krebs cycle to the electron transport chain
Answer:
The FADH2 and NADH molecules produced in glycolysis and the Krebs Cycle, donate high-energy electrons to energy carrier molecules within the membrane. ... After passing through the electron transport chain, low-energy electrons and low-energy hydrogen ions combine with oxygen to form water.

Q. Which of the following are true concerning living things? Check all that apply. (2 pts)
1: They contain a vital force absent in nonliving things.
2: They are composed of molecules that contain carbon-carbon bonds.
3: They undergo chemical reactions to use energy they acquire from the environment.
4: They do not require catalysts to sustain their living state.
Answer:
Explanation:
Answer: 2 They are composed of molecules that contain carbon-carbon bonds.
3. They undergo chemical reactions to use energy they acquire from the environment.
Living things includes all the organisms that display features which make them distinct from non-living organisms. The living organisms have an organized structure, they are composed of cells, they require energy to survive or sustain existence, they are able to reproduce and they exhibit ability to grow.
They are composed of molecules that contain carbon-carbon bonds: Carbon is the main component present in all living things. They make up the organic biomass of these living organisms.
They undergo chemical reactions to use energy they acquire from the environment: The plants traps sunlight energy and converts it into food and lastly into chemical energy in the form of ATP. This ATP is used as a energy reservoir for metabolic processes occurring in the plants. Therefore, energy is generated after chemical reactions.

The ribosomes within a prokaryotic cell are much larger than the ribosomes within a eurkaryotic cell.
The majority of prokaryotic cells are unicellular.
Prokaryotic cells lack membrane bound organelles.
The majority of prokaryotic cells are unicellular.
Answer:
The ribosomes within a prokaryotic cell are much larger than the ribosomes within a eurkaryotic cell.
Explanation:
Eukaryotic cells are generally much larger and more complex than prokaryotic. Because of their larger size, they require a variety of specialized internal membrane-bound organelles to carry out metabolism, provide energy, and transport chemicals throughout the cell.
Answer:
The ribsomes within a prokaryotic cell are much larger than the ribsomes within a eurkaryotic cell.
