Fish provide polar bears with 10 grams of biomass worth of energy.

Biomass is defined as a fuel made from organic materials; a sustainable and renewable energy source used to produce electricity or other types of power. Our ecology, economy, and energy security might all be significantly improved by using biomass as a clean, renewable energy source.

According to 10% rule.

1000x10%=100

100x10%=10.

When animals from one trophic level are consumed by organisms from the next trophic level, energy is lost when going from a lower trophic level to a higher trophic level because energy is lost as metabolic heat.

Thus, fish provide polar bears with 10 grams of biomass worth of energy.

In conclusion, gene editing has the potential to be misused and lead to unforeseen consequences, which can cause long-term damage to society.

Gene editing refers to the deliberate modification of the genetic composition of an organism. Editing genes can be done through the insertion, deletion, or replacement of DNA, which is done by using certain techniques like CRISPR/Cas9.Gene editing can be useful in many ways as it can help treat genetic disorders and help modify crops, which can help in solving world hunger.

However, some argue against gene editing and its potential implications. It is important to explore both sides and make an informed decision regarding gene editing. Here are two theoretical positions; one in favor of gene editing and another against gene editing.

In favor of Gene Editing

Gene editing has the potential to revolutionize the healthcare industry by treating and curing genetic disorders.

For instance, gene editing can help treat Huntington’s disease and cystic fibrosis. Through gene editing, we can insert functional genes into a patient’s genome to replace the defective genes. Moreover, gene editing can also help in developing genetically modified crops, which can help combat world hunger. For example, researchers can insert genes into crops that make them resistant to pests, disease, and adverse weather conditions. Gene editing also has the potential to reverse environmental damage.

In conclusion, gene editing has the potential to bring positive changes in the field of healthcare and agriculture, which can improve the quality of life for many people. Against Gene Editing Gene editing has the potential to be misused, and this can lead to ethical concerns. For instance, gene editing can be used to create “designer babies,” which can have a wide range of implications. Creating “designer babies” can lead to a social divide, where people with the means to edit their children’s genes have more advantages than those who don’t.

Moreover, gene editing can lead to unforeseen consequences, which can cause irreversible environmental damage. Gene editing can also result in the creation of superhumans, which can be a disadvantage to society as a whole.

wow thats tricky................  i think its asymmetrical or radial

Answer:

Bilateral

Explanation:

It is an living animal that has an even body.

The process of respiration can be divided into the cellular view to the general (cellular respiration to external respiration). Going from the cellular till the external we have:

1- Cellular respiration

Is the aerobic process by which living cells break down glucose molecules to form energy in the from of ATP, that can be divided in three stages, these are: glycolisis (break of glucose into pyruvate), Citric Acid Cycle (Krebs Cycle), and electron transport chain. In this respiration the cell machinery is responsible for from glucose and oxygen form water and carbon dioxide. All the process is intracellular.

2- Internal respiration

The internal respiration is the process of the exchange of gases between the cells and the tissues (internal environment of the body) by the blood vessels and the circulation od red blood cells that carry these gases (oxygen and carbon dioxide). The path of this process is: nose/mouth, pharynx, larynx, and trachea will have the cells oxigenated, the trachea branches and the bronchi will lead to the lungs when the gases exchanges in the tissue will happen. The red blood cells will do the local capture of the gases and the circulatory system will make those cells go to all the tissues in the body.

3- External respiration

The external respiration is the exchange of gases with the external environment. That process occurs in the lungs where the oxygen diffuses into the blood and carbon dioxide into the alveolar air. The internal and external respiration work together in the overall respiratory process, but one happen in the tissues and the other between external environments.

4- How they work together?

The three process are essential for breathing, that's because they work into different levels of tissue and systemic organization. The cellular is the one in the cells that provide the biochemical reactions necessary to the synthesis and conversion of molecules, being the metabolic basis for the respiration to take place, the internal respiration is responsible to distribute the gases into the tissues to make the cellular step possible, while the external respiration makes possible the exchange outside the tissues levels and makes possible to balance the distribution and concentration of the gases in the body.

The conclusion of the hypothesis test regarding the mean body temperature of a healthy adult is sufficient evidence to warrant rejection of the claim that the mean body temperature of a healthy adult is not 98.6∘F.

a) Null Hypothesis (H0): The mean body temperature of a healthy adult is 98.6∘F.

  Alternative Hypothesis (H1): The mean body temperature of a healthy adult is not 98.6∘F.

b) The hypothesis test should be two-tailed.

c) The appropriate significance level is 0.05.

d) The test statistic is calculated using the formula: (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size)). The result is -5.86.

e) The p-value is calculated by finding the probability of obtaining a test statistic as extreme or more extreme than the observed value under the null hypothesis. The p-value is 0.0000.

f) We reject the null hypothesis, since the p-value is less than the significance level.

Answer:

It's B :)

Explanation:

Answer:

The correct answer is ''complementary pairing of bases''

Explanation:

The double-stranded DNA with the complementary nitrogenous bases that are located inwards and establish non-covalent bonds (or attractive forces) to each other that maintain the structure of the molecule. Deoxyriboses (sugars) and phosphate groups constitute the columns of the molecule. When the cell divides, each new cell that is formed must carry all the genetic information that determines its characteristics and functions. For that, before dividing, DNA must replicate, that is, generate a copy of itself. During replication, the DNA molecule unwinds, separating its chains. Each of these will serve as a template for the synthesis of new DNA strands. The double-stranded DNA structure proposed by Watson and Crick (1953) suggested several important properties of the hereditary material: Complementarity rules of the nitrogenous bases A-T and G-C suggest a simple way of replication of the hereditary material. This simple form of replication is called a semi-conservative method. When DNA replicates, its two helices separate and each one of them serves as a template to synthesize a new helix following the pairing rules of nitrogenous bases.

Gated ion channels are open and close in response to a stimulus.

A stimulus in physiology is a perceptible alteration in the physical or chemical composition of an organism's internal or external environment. Sensitivity refers to an organism's or organ's capacity to recognize external stimuli and respond appropriately (excitability). As with touch receptors in the skin or light receptors in the eyes, sensory receptors can pick up information from both within and outside the body. Chemoreceptors and mechanoreceptors are examples of internal sensory receptors. A stimulus can trigger a response via stimulus transduction when it is recognized by a sensory receptor.

The description of being branched and striated is a characteristic that applies to the cardiac muscle tissue.  The right option is E.

This type of tissue is found in the heart and is responsible for the contraction of the heart muscles that help in pumping blood throughout the body.

The cardiac muscle tissue has the unique feature of being branched, which allows it to work as a unit and coordinate the contraction of the heart.

The striations in the cardiac muscle tissue are due to the arrangement of the contractile proteins, which give the tissue a striped appearance under the microscope.

Unlike skeletal muscles, which are under voluntary control, the cardiac muscle tissue is involuntary and works continuously to keep the heart beating.

Therefore, the answer to the question is E, cardiac muscle.

It is most likely that people who were able to produce a detectable antibody response also express MHC class II allotypes that bind efficiently to the 12 amino acid peptide expressed by the bacteria.

MHC Class II allotypes (also known as MHC alleles) are variations in the genetic code that lead to different forms of the MHC Class II molecule. They are responsible for presenting peptides (antigens) from pathogens (bacteria, viruses, etc.) to T cells of the immune system.MHC Class II molecules have two chains: alpha and beta. MHC Class II allotypes are due to differences in the genes that encode for these chains. They are highly polymorphic, meaning that there are many different versions of the genes that encode them.It has been found that the C57BL/6 strain of laboratory mice, after being given non-pathogenic bacteria that have been engineered to express a 12 amino acid peptide, produces IgG antibodies that neutralize IAV.

It has been determined that MHC Class II molecules are required to present the 12 amino acid peptide to T cells. As a result, it is likely that humans who express MHC Class II allotypes that are efficient at binding to the 12 amino acid peptide expressed by the bacteria will also produce detectable antibody responses.

The updating function that describes the situation is as follows: b_{t+1}=4b_t - 3 where b_t is the number of bacteria at hour t, measured in millions.

This function considers that the population of bacteria quadruples every hour but 3 million bacteria are removed after reproduction each hour to be converted into valuable biological by-products.

To put this function in slope-intercept form, we need to solve for b_{t+1}:b_{t+1}=4b_t - 3b_{t+1}+3=4b_t

This equation has a slope of 4 and a y-intercept of 3.
