A patient with osteoporosis (reduced bone mass) may have a history of health issues. One issue could be
not enough skin exposure to the sun to make Vitamin D.
weak ligaments.
an increase in the absorption of calcium in the digestive system.
weak tendons.
Answer:
not enough skin exposure to the sun to make Vitamin D.
Explanation:
The correct answer would be not enough skin exposure to the sun to make Vitamin D.
The body makes vitamin D by being exposed to the sun and this vitamin and its metabolite are quite important in the homeostasis of calcium. Calcium on its own is very essential to the formation of bones in the body.
Hence, when the skin is not adequately exposed to the sun, the body becomes short of vitamin D and this disrupts the homeostasis of calcium and the formation of bones in the body. Thus, osteoporosis, also known as weak bones, may result.
Answer:
(A) not enough skin exposure to the sun to make Vitamin D.

Answer:
The root of a huge tree causes cracks in a rocky surface. ---> biological Weathering.
Part of a cliff breaks and falls due to waves. ----> mechanical weathering
Acid rain reacts with calcite present in limestone---> chemical weathering
Explanation:
The root of a huge tree causes cracks in a rocky surface is the example of biological Weathering because in this weathering living organism is involved. Part of a cliff breaks and falls due to waves of water is the example of mechanical weathering because water enters the small pores of rocks and formed cracks when expands. Acid rain reacts with calcite present in limestone is a chemical weathering because acid present in rain water is responsible for the degradation and breakdown of rocks.

Which does not provide for enhanced genetic mixing?
A.Mix-matching
B.Random segregation
C.Crossing over
D.Fertilization that occurs through sexual reproduction
Answer:
A. Mix-matching
Explanation:
Sexual reproduction increases genetic variation in offspring by three main mechanisms: 1-random assortment of chromosomes during meiosis 2-genetic recombination, and 3-random fusion of gametes from different parents. In the first place, the pairs of homologous chromosomes are randomly oriented in metaphase I before they separate in Anaphase I. In consequence, daughter gamete cells receive different combinations of chromosomes. Second, recombination (also called crossing over) refers to the interchange of genetic material between non-sister chromatids during prophase I, thereby also increasing genetic variation in daughter cells. Third, the fusion of two haploid cells (i.e., gametes) in diploid organisms results in the formation of a single zygote cell that develops into a new organism, thereby the process of random fertilization between any two gametes generates different diploid zygotes, increasing thus genetic diversity.

Difference between plants in a tropical location, a temperate location, or the tundra?
Answer:
a tropical location as an area near the equator a temperate location is any area that that lies between the tropical and polar zones and a tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons.
In graph two, label A represents the gases hydrogen sulfide, methane, and carbon dioxide. What gases are represented by label B and how do these gas levels relate to the evolution of photosynthetic organisms?
Answer:
Oxygen.
Explanation:
Oxygen is the gas that is increased in concentration due to photosynthetic activities of plants and algae because in the process of photosynthesis, plants and algae absorb carbondioxide gas into the body and as a result, oxygen gas is produced. Some amount of oxygen is used by the plants in the process of respiration while the remaining is released in the atmosphere through stomata.

why is it a good idea for a bacterial cell to be abel to use glucose first as an energy source then switch to lactose
Answer:
Due to less steps and requires less energy.
Explanation:
The bacterial cell is able to use glucose first as an energy source then switch to lactose because glucose requires less steps and less amount of energy for the break down as compared to lactose. If lactose is the only sugar available to the bacterial cells, then bacterial cells will use it as energy source for the production of energy. In order to use lactose, the bacteria must express the lac operon genes, which encode the main enzymes for lactose uptake and metabolism.

In 1980, scientists suggested that the great mass extinction of 65 million years ago (which ended the reign of dinosaurs) may have been caused by a large impact from space. What discovery gives a big boost to this idea
Answer: the discovery of a buried crater (about 200 km across) near Chicxulub, Mexico
The discovery of a buried crater (about 200 km across) near Chicxulub, Mexico.
What is extinction?
Extinction is defined as the disappearance of an organism or a group of organisms as a result of environmental factors or changes in the members' evolutionary processes.
It can also be defined as an evolutionary process that causes a species or population to go extinct.
When there are no longer any living members of a certain animal or plant species anywhere in the globe, the species has become extinct.
Generally speaking, species disappear for the following reasons:
Genetic and demographic phenomena.Habitat destruction in the wild.Species introduction that are invasive.Global warmingHunting and illicit trade.Thus the discovery of a buried crater (about 200 km across) near Chicxulub, Mexico.

Write two sentences or clues, one for each word, that will help you remember the difference between actin and myosin. (Example: Actin is actively pulled)?
Answer:
The correct answer is -
Actin produces thin contractile filaments within muscle cells,
Myosin produces the dense contractile filaments within muscle cells
Explanation:
Actin is a globular protein that makes actin filaments by arranging in the long spiral chain or produces thin contractile filaments within muscle cells. It is found in cell cytoplasm as well as in the nucleus in eukaryotic cells.
Myosin is a motor protein that produces the dense contractile filaments within muscle cells and plays role in generating movement and force from chemical energy.

Formation of an RNA hairpin cannot be the sole factor in the termination of transcription in prokaryotes. Explain why.
Answer:
As the transcription process proceeds, a variety of secondary structures forms by the nascent RNA. t takes place due to the fact that portions of the transcript as complementary base pairs form.
The transcript could be pause but terminate, the hairpin loop causes RNA Pol to pause. There are two different ways to terminate transcription in prokaryotes
- intrinsic termination: in this no external factors required
- Rho protein termination: binds to end of msg and moves along by ATP hydrolysis to catch up (rho is faster)

what use are the descending branches of glacial plants to them?
Answer:
Explanation:
A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow under stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques, moraines, or fjords. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that forms on the surface of bodies of water.
