Asexual reproduction differs from sexual reproduction in that Group of answer choices asexual reproduction utilizes DNA from two parents to code for traits in offspring. asexual reproduction occurs only in plants. asexual reproduction produces offspring containing DNA from only one parent. asexual reproduction only occurs in animals. asexual reproduction produces genetically diverse offspring.

Answers

Answer:

Asexual reproduction produces offspring containing DNA from only one parent.

Explanation:

Asexual reproduction produces offspring containing DNA from only one parent because in asexual reproduction, the organisms born or produced from a single parent. The offspring is identical to their parent and this process of asexual reproduction occurs in both plants and animals. Asexual reproduction produces identical not genetically diverse offspring in the end of the process.

Answer:

Because asexual reproduction results in the birth or creation of organisms from a single parent, the children created have DNA from just one parent. Both plants and animals can reproduce asexually, and the progeny are identical to their parents. Asexual reproduction ultimately results in identical, not genetically different, offspring.

Formation of an RNA hairpin cannot be the sole factor in the termination of transcription in prokaryotes. Explain why.

Answers

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)

Answers

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.

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.

Select the correct answer from each drop-down menu. Study the graphs, and then complete the passage. An anomaly in global temperature is a deviation from what is normal or expected. The graph shows that global atmospheric co2 ___(increased exponentially. Remained constant. Increased slightly)in the twenty-first century, and global temperature also increased during the same time. Based on the timeline, these statistics suggest a correlation between climate change and ___(wind energy production. Use of electric cars. Industrial carbon emissions). If the current trend of increasing co2 levels continues, the greenhouse effect will continue to ___(warm the planet. Release gas into space. Destroy carbon dioxide) .

Answers

Answer:

Increased exponentially

Industrial carbon emission

Warm the planet

Explanation:

The rapid increase in global CO2 in the 21st century has raised concerns over the lingering effect of global climate change which could result due to the exponential increase in CO2 emission at this time. This rise in global atmospheric CO2 has been observed to have a positive relationship with the level of industrial carbon emission. The rise in emission of industrial carbon has been tipped to be responsible for the exponential rise in global atmospheric CO2. CO2 is a form of green house gas responsible for warming the planet.

Answers

Answer:

Dwarfism

Explanation:

Dwarfism is a growth disorder characterized by a height that is much lower than the average for people of the same race and age. Individuals with proportionate dwarfism have excessively short bodies but the dimensions of all their parts are proportionally smaller. It is due to certain diseases that are already present at birth or that manifest themselves during early childhood, and that block the normal development of their body, such as the deficiency or deficit of growth hormone is when there is not enough hormone growth released by the pituitary gland. Dwarfism does not directly lead to a deficiency in the intellectual capacities of the individual, in general their mental development is normal.

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.

Answers

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.

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?

Answers

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.

what use are the descending branches of glacial plants to them?​

Answers

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.

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

Answers

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.
