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
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.
[ 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.)
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.

Describe how Light year, AU and Kilometers are different?
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. Astronomers give the Earth's changing distance throughout the year relative to the astronomical unit, to

plz halp Name two mammals that might pollinate a plant.
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.

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
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.

The correct answer is to Represent the locations of subatomic particles in different atomic theories.
Explanation:
Atoms, which are the basic unit of matter in the universe are composed of subatomic particles (protons, neutrons, electrons). Moreover, during history atoms have been represented through different models that differ in their general structure as well as the location of sub particles.
This can be seen in the image presented because Thompson's model purposes electrons, which are represented by circles with the negative sign, are distributed inside a positively charged substance. On the other hand, Bohr's model proposes protons are in the center and electrons orbit around it, which shows different locations of sub-particles.
Asthma is a chronic condition that affects a person's ability to breathe. Every year many people are rushed to the hospital because of severe asthma episodes. Air quality is a major trigger for asthma events in children aged 5 - 14. On a daily basis NYC posts air quality information to inform the city residents if it is a high risk day for asthma. Below you will find information summarizing persistent asthma in children aged 5 - 14 in NYC during 2013-2014. Pretend you are on a committee to create an action plan to improve air quality in NYC and use the data presented to select the target borough and neighborhood to begin your plan. Provide evidence to support your response.
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.

How does a tree use Cellular Respiration to store carbon?
Flow of Matter (atoms) in Cellular respiration
Answer:
In-spiration Respiration in trees releases energy stored in carbon compounds through a controlled process. Aerobic respiration uses O2 to oxidize organic compounds into CO2 and H2O. Energy released is stored within living cells as ATP, ETM, and a proton bank which are easily used for cell work.

Bacteria were some of the first organisms to be genetically modified because they have
a relatively small genome and reproduce quickly. All of the following are reasons to
study and modify a bacterial cell's genome for beneficial uses except
to use bacteria cells as a vector to add genes that code for useful products.
O to determine the genes that code for proteins such as those used to produce insulin in large
amounts.
O to modify bacteria into an infectious form that has the ability to mutate quickly.
to determine genes that code for toxins against other bacterial cells to make antibiotics from
these toxins.
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.
