Answer:
The correct answer would be C. Salt crystals are hard and brittle because they are made up of atoms that combine by ionic bonding.
Explanation: All the other ones are chemical changes because a new substance is formed.
The statement that describes a physical property related to the particles that make up material is as follows:
Salt crystals are hard and brittle because they are made up of atoms that combine by ionic bonding.Thus, the correct option is C.
What is Physical property?Physical property may be defined as a property of matter or substance that is not associated with alterations in its chemical composition.
An example of iron nails involves a chemical reaction to occur and a result of which chemical composition alters. Options B and D are naturally occurring phenomena that do not involve any physical manifestation.
Therefore, the correct option for this question is C.

Which type of mutation often has the least effect on organisms' traits (and may have no effect at all)? Nondisjunction Substitution Insertion Deletion
Answer:
The correct answer is - substitution.
Explanation:
Substitution mutations are the point mutations that are the mutations that least likely affect the trait of an organism or have no effect at all. Substitution mutations take place when there is only one nucleotide base is substituted by another nucleotide base in the DNA or RNA of an organism's genome.
In this case, there is no effect found on the protein formed by these DNA sequences. These substitution mutations generally found in somatic cells and have little to no effect at all.

Answer:
c & d
Explanation:
I just took the quiz and I got D correct. I'm not sure about C but the rest of the options don't make sense, so it's probably C.
A bacterial cell which is producing spider venom protein is an example of genetically modified organism and a transgenic organism. Thus, the correct options are C and D.
What are Transgenic organisms?
Transgenic organism refers to those organisms or cells whose genome has been modified or altered by the introduction of one or more foreign DNA sequences which are beneficial from another species through artificial means. Transgenic organisms are generated in the laboratory for research purposes.
A bacterial cell which is making a protein that is normally found in spider venom is an example of genetically modified or transgenic organism as in these organisms the genome of the organism is modified or altered as per the requirements.

Both producers and consumers can be animals.
Both producers and consumers make their own food.
Both producers and consumers use energy that started from the sun.
Producers and consumers are related as both producers and consumers use energy that started from the sun.
What do you mean by Producers?Producers may be defined as the organisms which use the energy of the sunlight directly to synthesize their own food. They are always found at the root of each ecosystem.
Producers are plants while consumers are animals. Only producers can make their own food, while consumers can get their food by feeding on plants.
Producers directly use the energy from the sun, while consumers derived the energy from eating producers.
Therefore, producers and consumers are related as both producers and consumers use energy that started from the sun.

Which body system is responsible for producing offspring
Answer:
The Reproductive System
Explanation:
In living things, the reproductive system is responsible for producing children. It is a group of hormones, tissues and organs that cooperate to promote the conception and development of new ones.
Men have a variety of reproductive organs, including the testes, epididymis, vas deferens, prostate, etc. Sperm production and distribution are facilitated by these structures. In women, the reproductive system includes the uterus, fallopian tubes, cervix, and vagina, among other structures.
These organs play an important role in the development of the egg during pregnancy, fertilization, implantation of the fertilized egg, and the growth and development of the fetus. Additionally, the reproductive system contains hormones that control reproduction, such as testosterone in males and estrogen and progesterone in females.

Charles has developed a new advertisement that can be used online. He tests how well it draws people's attention by closely
monitoring the eye movement of 1,000 test subjects as the new ad appears on their computer screens!
Charles finds that 97% of the test subjects' eyes were drawn toward the ad when it appeared. By comparison, only 50% of the test
subjects' eyes were drawn toward a box of plain text when it appeared instead. He concludes that the new ads are better at
attracting people's attention than old ads.
What is wrong with Charles' experiment?

Calcium-41 has a half-life of 80,000 years. At the end of 240,000 years,
how much Calcium-41 would remain in a sample initially containing 60
micrograms? *
A 7.5 micrograms
B 60 micrograms
C 15 micrograms
D 30 micrograms
If the half-life is 80,000 years, then 240,000 years would be equivalent to three half-lives. In other words, the initial amount of the radioactive calcium-41 would have been reduced in half three times over. Mathematically, this can expressed as
calcium-41 remaining = initial mass of calcium-41 × (0.5)³.
Since we are given the initial mass of calcium-41, the amount of calcium-41 remaining after 240,000 years would be:
60 μg × (0.5)³ = 7.5 μg, or 7.5 micrograms.
