Explain in term of osmosis, why a raisin placed in a cup of pure water overnight will puff up with water

Answers

Answer 1
Answer: In the term of osmosis, solvent molecules will move in the direction that will equalize the solute concentrations.

Since the concentration in cup of water is greater than the raisin, to equalize it , the concentration will flow from the cup to the raisin

Answers

Co-evolution

Explanation:

The given statement implies that arthropods had more time to co-evolve with land plants than vertebrates

  • Co-evolution is a type of evolution in which two species reciprocally affect each others evolution in a way that they both evolve together
  • Fossil evidence gives the progressive interaction between arthropods and land plants through the later Paleozoic and Mesozoic era
  • Evidence includes the evolution of chemical defense strategy by plants along with the evolution of different mouthpart design in new insect groups
  • Leaf galls became common in  Cretaceous coinciding with the evolution of several new insect groups and plants
  • Data from coprolites(trace fossils) suggest that spore feeding preceded leaf feeding,experiments have indicated that some spores remain viable after passing through the gut and hence this feeding habit might have been advantageous to some early plants for propagule formation

10) Which of the following describes a metabolic consequence of a shortage ofoxygen in muscle cells?
о
(A) An increase in blood pH due to the accumulation of lactic acid
O
(B) NO ATP production due to the absence of substrate-level phosphorylation
о
(C) A buildup of lactic acid in the muscle tissue due to fermentation
O (D) A decrease in the oxidation of fatty acids due to a shortage of ATP

Answers

The statement 'a buildup of lactic acid in the muscle tissue due to fermentation' describes a metabolic consequence of a shortage of oxygen in muscle cells (Option C).

  • Aerobic cells normally produce energy by cellular respiration.

  • Cellular respiration is a process by which aerobic cells produce energy in the form of ATP by using the energy stored in the bonds of foods (e.g., glucose) and oxygen.

  • Acid lactic fermentation is a process by which muscle cells can produce ATP in anaerobic conditions.

  • This process (acid lactic fermentation) is less efficient than cellular respiration in terms of production of ATP per molecule of glucose, but it is faster.

In conclusion, the statement 'a buildup of lactic acid in the muscle tissue due to fermentation' describes a metabolic consequence of a shortage of oxygen in muscle cells (Option C).

Answer:

The correct answer is - C) a buildup of lactic acid in the muscle tissue due to fermentation.

Explanation:

In absence of enough oxygen for the muscle cells to perform the aerobic pathway to breakdown pyruvate for energy, the body starts producing lactic acid to convert glucose into energy.

This process is known as fermentation which can produce lactic acid and build it in muscle cells. There are some negative effects of fermentation and buildup of lactic acid in muscle cells such as cramps, pain, and fatigue in the muscles.

What are some real world problems and how can biology be used to solve these
problems?

Answers

The real world problems are explained below:

  • Lack of energy resources

Various non-renewable energy resources like natural gas and fossil fuels. We can use biology to help with the development and improvement of renewable energy sources like hydroelectric energy.

  • Food scarcity in developing countries

Many countries have issues with starvation and famine. It's usually due to there are various people in a dry, desolate area, like as Yemen, or Afghanistan, where it's very difficult to grow food. We can use biology to create or generate new seeds.

Answer:

a. Lack of energy resources

Many non-renewable energy resources, such as natural gas and fossil fuels, and quickly being used up. We can use biology to help with the creation and improvement of renewable energy sources, such as geothermal or hydroelectric energy.

b. Food scarcity in developing countries

Many third world countries have issues with starvation and famine. It's usually because there are many people in a dry, desolate area, such as Yemen, Niger, or Afghanistan, where it's difficult to grow food. We can use biology to develop new seeds that can withstand extreme heat or drought, to combat famine in these countries.

Which best describes the lytic and lysogenic cycles?Unlike the lytic cycle, the lysogenic cycle involves production of virus particles.
Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.
Symptoms of infection appear in the lysogenic cycle but not in the lytic cycle.
For virulent viruses, the lysogenic cycle is the main way of replicating.

Answers

Answer: Unlike the lysogenic cycle, the lytic cycle involves destruction of the host

Lysogenic cycle is a method by which virus can replicate its DNA using the host cell mechanism. During this phase bacteria integrate its DNA in to host cell to make viral copy to infect the organism.

The lytic cycle is another way of the viral replicaton, it results in the destruction of infected cell and its membrane. In this cycle bacteria make viral DNA and viral protein and break and allow the newly produced virus to leave and now integrated to new cells to spread infection to other cell.
The answer is: Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.

In the lysogenic cycle a virus does not kill the host. Regarding the other statements, in the lytic cycle symptoms of infection appear, and, also, it is the main way of replicating virulent viruses.

Recent research has demonstrated a correlation between the presence of certain types of Gram-positive bacteria in the human gut with obesity and type 2 diabetes. These findings best support which of the following statements?a.) Normal microbiota may significantly impact human health and disease.

b.) The presence of Gram-positive bacteria in the human gut causes obesity and type 2 diabetes.

c.) Gram-positive bacteria compose the majority of normal microbiota in the human gut of people with obesity and type 2 diabetes.

d.) Obesity and type 2 diabetes is caused by normal microbiota in the human gut.

Answers

Answer:

The correct option is A. Normal microbiota may significantly impact human health and disease.

Explanation:

A wide number of microorganisms are present on or inside of our body. All these microorganisms make up the natural microbiota. The normal microbiota is very important to maintain the health of the host.

However, any microbial imbalance can lead to causing disease in its host. The microbiota of the gut have a disease-promoting effect but can also have protective properties. Differences in this microbiota can lead to serious conditions.
