What is an example of symbiosis?
A. competition
B. parasympathetic union
C. commensalism
D. morphing

Answers

Answer 1

An example of symbiosis is commensalism. The correct answer is option c.

What is symbiosis?

Symbiosis refers to a relationship that exists between two different organisms or species that are usually living together in close association.

The relationship may be beneficial, detrimental or neither to any of the involved organisms. There are different types of symbiotic relationships, including mutualism, commensalism, and parasitism.

Commensalism

In commensalism, one of the species benefits from the relationship while the other remains neutral.

For instance, barnacles that attach themselves to a whale can help the barnacles move from one location to another while the whale remains unaffected. In this case, the barnacle benefits while the whale is not affected in any way.

Therefore, commensalism is an example of symbiosis. The correct answer is option c.

Amino acids found in the amino acid pool __________.
A. can be used for protein synthesis
B. help to synthesize essential amino acids
C. must come from animal products
D. require protein supplements to maintain their resources

Answers

Amino acids found in the amino acid pool A. can be used for protein synthesis

The amino acid pool refers to the collection of amino acids available within an organism's cells and tissues. These amino acids can be derived from various sources, including dietary protein intake and the breakdown of cellular proteins. The amino acids in the amino acid pool can be utilized for a variety of cellular processes, including protein synthesis.

Option B is incorrect because the amino acid pool does not directly synthesize essential amino acids. Essential amino acids are those that cannot be synthesized by the body and must be obtained through the diet.

Option C is also incorrect because the amino acids in the amino acid pool can come from both plant and animal sources. While animal products tend to be good sources of complete proteins containing all essential amino acids, plant-based sources can also provide individual amino acids that can contribute to the amino acid pool.

Option D is incorrect because the amino acid pool does not require protein supplements to maintain its resources. The body can recycle amino acids from protein breakdown and utilize them as needed. While protein supplements can be used to supplement protein intake, they are not essential for maintaining the amino acid pool.

So, option A is the correct answer.

Answers

The event which occurs during the normal function of ATP in the cell is the chemical bond breaks between the second and third phosphate groups.

A vital "energy molecule" present in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers energy to cells by releasing its phosphate groups when it interacts with enzymes like ATP triphosphatase.

The 1′ carbon atom of a sugar (ribose) is bonded by the 9-nitrogen atom of an adenine, which is then joined to a triphosphate group at the sugar's 5' carbon atom. The adenine and sugar groups are unaltered in its numerous metabolic processes, however the triphosphate is transformed into di- and monophosphate, yielding respectively the derivatives ADP and AMP.

Answers

Innate defenses are present at birth and provide mostly nonspecific resistance to infection, whereas adaptive defenses are specific defenses that must be acquired.

Innate or general defences stop or restrict the movement, invasion, and spread of microbes and other environmental threats. These defences frequently work independently of other defences to eliminate germs and avoid infection. However, occasionally the non-specific defences require assistance from the adaptive immune system. The initial line of protection is comprised of undamaged skin and mucosae, which are known as nonspecific defences. The second line of defence is triggered when germs enter the skin or mucosae. Internal defences, such as phagocytes and antibacterial proteins, are necessary for this. The most crucial mechanism in the second line of defence is inflammation. Mechanical barriers that cover bodily surfaces and chemical compounds that interact with invasive infections are two examples of nonspecific defences.

The history of climate change

Write one paragraph of the history of climate change.

Answers

The Sun serves as the primary energy source for Earth’s climate. Some of the incoming sunlight is reflected directly back into space, especially by bright surfaces such as ice and clouds, and the rest is absorbed by the surface and the atmosphere. Much of this absorbed solar energy is re-emitted as heat (longwave or infrared radiation). The atmosphere in turn absorbs and re-radiates heat, some of which escapes to space. Any disturbance to this balance of incoming and outgoing energy will affect the climate. For example, small changes in the output of energy from the Sun will affect this balance directly.

Change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change Earth's energy balance and climate. Many other theories of climate change were advanced, involving forces from volcanism to solar variation. In the 1960s, the evidence for the warming effect of carbon dioxide gas became increasingly convincing. Some scientists also pointed out that human activities that generated atmospheric aerosols could have cooling effects as well.

why is intra species competition more problem than the inter species competition

Answers

Intraspecific competition are more intense than interspecific competition because the individuals have the same niche so they are competing for exactly the same resources.

Intraspecific competition can be intense at high population densities. Because High population density leads to reduced survival rates, slow growth rate and decreased reproductive rate .

Competition is assumed to shape niche size, affecting survival rate of species and coexistence. For example  As the density of plants increases, there is a corresponding decrease in performance, reflected in a reduction in the overall size and weight of plants. Intraspecific competition is an interaction in population ecology, where same species compete for limited resources.

In roses assume that red or yellow flower color is controlled by a single gene with two alleles. Crossing roses with yellow flowers with each other yields only offspring that produce yellow flowers, but when you cross roses with red flowers with each other you sometimes get offspring that produce yellow flowers. If you take a rose plant that is heterozygous for the flower color gene and cross it with another rose plant with red flowers that has had yellow-flowered offspring in the past, what are the predicted fractions for the possible phenotypes of the offspring?.

Answers

The predicted fractions for the possible phenotypes of the offspring are 3/4 red and 1/4 yellow.

The genotypes of the offspring of this hybrid can be used to predict the proportions of phenotypes. Offspring with either the PP or Pp gene will have the red-flower phenotype because P is dominant to p.

The yellow-flower phenotype can only be inherited through the pp genotype. As a result, with this cross, you would anticipate that three of the four (75%) progeny will have red flowers and one of the four (25%) would have yellow flowers.

Answers

Protein metabolism is difficult because nitrogenous wastes like ammonia and urea build up. This is the answer. A long answer is given below.

Protein metabolism is one of the most complex processes carried out by living organisms because it includes the breakdown of amino acids and their conversion into other amino acids, sugars, fats, and other metabolic intermediates. The products of protein metabolism, which include nitrogenous wastes like ammonia and urea, are potentially toxic and must be removed from the body. The liver is responsible for metabolizing the nitrogenous wastes produced by protein metabolism, which are excreted by the kidneys.

If the liver or kidneys are damaged or functioning poorly, the buildup of nitrogenous wastes in the bloodstream can lead to serious health issues. Additionally, the energy required for protein metabolism is higher than that required for other types of metabolism, as proteins contain 9 kcal/gram of energy, compared to 4 kcal/gram for carbohydrates and fats. Therefore, the body must expend more energy to break down and metabolize protein. Finally, ATP cannot be made from protein, as it can from carbohydrates and fats, which are more efficient energy sources. As a result, the body must use protein to make glucose or fatty acids, which can then be used to produce ATP.
