Answer:  Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.

Answer:

Active heating captures sunlight, either as heat or electricity, to augment heating systems, while passive heating captures heat from the sun as it comes into your home through windows, roofs and walls to heat objects in your home (hope that helped?)

Explanation:

The more closely related two different species are, the more alike their cytochrome C amino acid sequences are. The cytochrome C is an evolutionarily conserved protein.

The cytochrome C  is an evolutionarily conserved protein involved in cellular respiration.

The cytochrome C is a carrier of electrons that acts during the oxidative phosphorylation stage of cellular respiration.

This protein is evolutionarily conserved in species whose cells generate ATP in anaerobic (oxygen presence) conditions, which means that generally synonymous mutations are observed when comparing the amino acids of this protein.

Answer:

deoxygenated blood is pumped back to the heart with the superior vena cava and inferior vena cava. Blood is then in the right atrium then it is pushed to the right ventricle in the heart. it is the pumped through the pulmonary artery to the lungs(the pulmonary artery is the only artery that carries deoxygenated blood). In the lungs blood is pumped to the cappilleries in the bronchus where oxygen in the air is passed through to the blood with heamoglobin and thus now the blood is oxygenated. The blood is the pumped brought back to the heart with the pulmonary vein(the pulmonary vein is the only vein to carry oxygenated blood).It flows into the left atrium where it is then pushed down into the left ventricle and is then pumped up through the aorta to the whole body.

Answer:

Archaea and bacterial cells lack organelles or other internal membrane-bound structures. Therefore, unlike eukaryotes, archaea and bacteria do not have a nucleus separating their genetic material from the rest of the cell.

Explanation:

Answer:

50%

Explanation:

To solve this, we'd need to use a Punnett square.  Since the mother has a heterozygous genotype and has an A-blood phenotype, we know that she is AO and the father is AB.

          A             B

A       AA           AB

O      AO           BO

According to this, the four possible blood types, with equal probability are: AA, AB, AO, and BO.  Both AA and AO genes will result in type-A blood, since A is dominant over O.  Therefore, there is a 2 in 4 (or 1 in 2, or 50%) chance of the child having type-A blood.

Answer:

Mitochondria is found in animal cells.

General Formulas and Concepts:

Cellular Respiration

Explanation:

The production of ATP is found mainly in the mitochondria. Producing ATP must undergo cellular respiration. All plants and animals go through cellular respiration to provide energy for everyday actions needed by cells. Therefore, both plants and animals have mitochondria.

Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water.

Explanation:

The most highly sensitive time within the developing embryo for the risk of malformation related to environmental teratogens is cleft palate at 8 weeks gestation. It is an opening in the roof of the mouth.

A teratogen is any substance and/or physical agent that may cause an irreversible abnormality in the structure of the developing embryo or fetus (e.g., classical pesticides such as DDT).

Cleft palate is a malformation mainly caused by mutagenic agents (teratogens) during pregnancy, which affects approximately one (1) of 650 births.

A cleft palate is a malformation that occurs when the two plates of the skull that form the roof of the mouth cannot be completely joined.
