Describe how Light year, AU and Kilometers are different?

Answers

Answer:

1. difference of light year and AU 2. difference of kilometers and AU

Explanation:

1.A light year is the distance light travels in a year. ... One light year is almost six trillion miles. And an astronomical unit is the average distance between the earth and the sun. So the distance to the sun is by definition one AU.

2. More exactly, one astronomical unit (AU) = 92,955,807 miles (149,597,871 km). Earth's orbit around the sun isn't a perfect circle. So Earth's distance from the sun changes throughout the year.

Which of the following supports the idea that the genetic code is common to all living things? All living things have -
A. similar modes of reproduction
B. genes using the same nitrogenous bases
C. Identical ways of using energy
D. Adoptations that help them survive

Answers

Answer:

The statement that supports the idea that the genetic code is common to all living things is All living things have genes that use the same nitrogenous bases (choice B).

Explanation:

All living organisms possess DNA, a nucleic acid molecule that contains all the genetic information of living beings.  This information is transcribed into mRNA, where it becomes the genetic code that determines the synthesis of biomolecules, such as proteins.

The DNA molecule is made up of sequences of four nitrogenous bases: adenine, guanine, thymine and cytosine. These nitrogenous bases are common in the DNA of all living organisms.

Since genes consist of DNA fragments, with specific sequences of the same nitrogenous bases, then it is true to state that all living things have genes that use the same nitrogenous bases.

The other options are not correct because:

    A. Living organisms have different ways of reproduction.

    C. The way living things use energy is different, and there is no evidence that the genetic code is common to all of them.

    D. The way organisms adapt is not supported by the fact that they possess a common genetic code.

Answers

Answer:

Bats are probably the best-known mammal pollinators. Hundreds of plants rely on these busy, flying nectar lovers to spread their pollen at night, especially in tropical and desert environments. and butterflies

Explanation:

hope this helps have a good night/day :)

Two mammals that might pollinate a plant are bats and bees.

1. Bats: Bats are known to be important pollinators, especially in tropical and desert regions. They are attracted to the sweet scent and nectar of certain flowers.

As they feed on the nectar, their bodies come into contact with the reproductive parts of the flower, facilitating the transfer of pollen from the male reproductive organs (stamens) to the female reproductive organs (pistils) of the flower.

2. Bees: Bees are one of the most well-known and important pollinators. They are attracted to flowers for their nectar and pollen. As bees move from flower to flower, pollen grains stick to their bodies, including specialized structures such as their hairy legs and bodies.

When they visit another flower of the same species, some of the pollen is transferred to the pistil, enabling pollination.

Answers

Answer:

By using electric appliances.

Explanation:

By reducing the use of appliances that run with fuels such as stoves, fireplaces, gas or kerosene heaters, and oil and gas furnaces etc. These appliances produces nitrogen dioxide gas which is responsible for the pollution of air and leads to asthma disease. So as a committee member I will suggest to reduce the air pollution by using electric appliances instead of fuel appliance because electric appliances does not produce nitrogen dioxide gas.

[ HELPPPP ] Write a paragraph explaining how a forensic scientist uses the scientific method. (You need a process or steps of the scientific method and how it relates to the job of a forensic scientist.)

Answers

Answer:

The scientific method is a process for experimentation that is used to explore observations and answer questions. Does this mean all scientists follow exactly this process? No. Some areas of science can be more easily tested than others. For example, scientists studying how stars change as they age or how dinosaurs digested their food cannot fast-forward a star's life by a million years or run medical exams on feeding dinosaurs to test their hypotheses. When direct experimentation is not possible, scientists modify the scientific method. In fact, there are probably as many versions of the scientific method as there are scientists! But even when modified, the goal remains the same: to discover cause and effect relationships by asking questions, carefully gathering and examining the evidence, and seeing if all the available information can be combined into a logical answer.

What is not true about ionic bonds? They have low melting points, they conduct electric current when dissolved in water, they form hard brittle crystals

Answers

Answer:

Explanation:

This is because ionic bonds have high melting point because they are held together by strong electrostatic force which hold the opposite charges together. This make the lattice to have lot of ions and alot of energy is required to overcome it, hence they have high melting and boiling points.

Ionic bond is a bind that have electrostatic attraction between atoms of opposite ions.

3. 3CO2 + 3H2O + 3O2® C6H12O6
4. 6O2 + 6H2O ® C6H12O6 + 6CO2

Answers

Answer:

1. 6CO2 + 6H2O → C6H12O6 + 6O2

Explanation:

The left side of the equation, or the reactants side, should have 6 carbon dioxide and 6 water.

So, the left side should have 6CO2 + 6H2O

The right side of the equation, or the products side, should have 1 glucose and 6 oxygen.

So, the right side should have C6H12O6 + 6O2

The correct answer is 1. 6CO2 + 6H2O → C6H12O6 + 6O2

It’s asking what you would do so I would pick the first on and that would say “ Imagine you have a terminal illness. Your physicians informs you that in attempting to treat your illness, all known interventions or treatments have been tried, but have all shown to be ineffective. This effectively leaves you without viable treatment options. This situation is a reality for a significant amount of patients who then, ideally, receive palliative care to attempt to provide the best possible end of life. However, imagine your physician informs you that she is aware of a new drug that is currently in development. This drug has had promising results in laboratory and animal testing, and has also undergone phase I and phase IIa testing on human participants. Currently, a phase IIb randomised clinical trial (RCT) is being set up. Imagine you set your hopes on this new drug and would like to get access to it, what are your options? One option is to wait for the drug to get market approval and reach the market. However, such testing takes time. Available research suggests that the average time from the first clinical tests on humans (phase 0 or I) to market approval is more than 7 years [1]. Terminally ill patients are thus likely to pass away before this medical intervention reaches the market, making this an unviable option.

Another alternative is to attempt to get enrolled in randomised controlled trial (RCT) for the drug which gives you a decent chance of receiving the experimental new agent. It is not assured you receive the drug since there is likely to be a control group receiving a placebo or the best currently available treatment and you could be (randomly) assigned to this group. Such clinical trials have a strong allure for terminally ill patients, and it is known that they will often ‘try anything to stay alive’

However, such a strong willingness of terminally ill patients potentially poses problems. First, it might make the offer or option to participate in an RCT a coercive one that some patients are unable to refuse. This might invalidate free and informed consent [3], although others have argued that this is not necessarily the case [4]. Second, it has been argued that it might even compromise the clinical trial system. Schuklenk (2014), for example, uses the example of AIDS trials in the past and argues that: ‘[Patients] lied and cheated to get into trials and left trials in such large numbers as to threaten the viability of the AIDS clinical trials system.’ ([5]: p.21).

As such, there is increasing attention for other ways to provide terminally ill patients with access to experimental and innovative drugs.

these toxins.

Answers

Answer:

To modify bacteria into an infectious form that has the ability to mutate quickly

Explanation:

Genetic modification has given us many useful discoveries. In the given question, you are given several of them related to the genetic modification of bacteria. The only harmful example you were given is the third one.

If someone modifies bacteria into an infectious form, they will spread more quickly and easily. That would lead to many people getting ill and possibly dying. Also, the faster bacteria mutate, the harder they are to deal with. This means that one type of antibiotic wouldn't be enough to cure all people who are ill. There is a possibility that new antibiotics would have to be invented, which takes time and research.

This is why the third option is the correct one.
