what makes one mineral harder than the other? Explain
Answer:
The hardness of a mineral is mainly controlled by the strength of the bonding between the atoms and partly by the size of the atoms. It is a measure of the resistance of the mineral to scratching, the Mohs scale is for natural minerals.
Answer:The ones that are tightly bound together look different than do ones with looser bonds. For example, in the illustrations below, (A) shows the atomic structure of carbon in a diamond, and (B) is the carbon arrangement in graphite. (A) is more compact than (B), hence it is harder.
Explanation:Rocks are made of minerals, and different minerals have different crystal structures. The chemical bonds that hold atoms together in these minerals are stronger in some than in others, and the atoms themselves determine which bonds are stronger than others.

p.s I know u got the answer but I still try to give u mine
whats this,in order?
Answer:
1. Individuals in a species vary in characteristics because of differences in their genes.
Individuals will be born with various characteristics due to their genes for instance some people are short and other are tall.
2. Individuals have to compete when resources (such as food) are limited.
Resources are generally limited so individuals would have to compete t get those resources and survive.
3. Individuals with variations that help them get more of the resources are more likely to survive.
Some of the characteristics that these individuals have which are different will give them an edge and enable them to get more resources and thus survive.
4. Individuals that survive can pass their genetic variations on to their offspring.
The individuals that survive will now have offspring and will pass on their genes to their offspring which give give them the same edge their parents had.
5. Over time, there are more individuals with the variations that are well adapted to the environment.
Eventually there will be more of those offspring that can adapt as opposed to those who couldn't and keep dying out.
Which factor in this swamp is abiotic?
A. Grass
B. Trees
C. Algae
D. Water
Answer:
D. Water
Explanation:
Biotic factors are all living things, and they are derived from organisms. These include: fungi, plants, bacteria, archaea, protists, animals.
Abiotic factors are all nonliving things, and they are not derived from organisms. These include: air, soil, light, water, minerals.
In this case, grass, trees, and algae are all living things since they are derived from organisms.

describe the subcellular structures that found in all bacteria
Answer:
The subcellular structures found in bacteria are: cell wall, cytoplasmic membrane, cytoplasm, ribosomes, vacuoles, plasmids, nucleoid —circular DNA— and annexes, such as pili, cilia and flagella.
Explanation:
Bacteria are unicellular prokaryotic organisms, characterized by a simple structure, lacking a nucleus and most of the organelles, with a circular DNA molecule that is free in the cytoplasm.
The sub-cellular structures present in the bacetry are
Cell wall, surrounding the plasma membrane, composed of peptidoglycan. Plasma membrane of lipidic nature, which covers and protects the cytoplasm. It is possible to find in some bacteria two plasma membranes.Cytoplasm, lacking endomebrane system. Nucleoid is not a true nucleus with nuclear membrane, but corresponds to circular DNA that is free in cytoplasm. Plasmids are fragments of DNA that are associated with the nucleoid, useful for the exchange of genetic material with other bacteria. Ribosome, which participate in the synthesis of bacterial proteins.Vacuoles are structures that are responsible for the storage of reserve substances, useful for bacterial metabolism. The structures annexes to bacteria are the pili, cilia and flagella. The pili are small villi present on the bacterial surface and participate in the process of intercellular communication and conjugation in prokaryotes. Cilia and bacteria serve for the mobility of bacteria.Which of the following is true about moss sporophytes?

Scientists are looking to determine the primary productivity of a lake by analyzing its oxygen net primary productivity. How are scientists able to measure how much oxygen is used during a plant’s cellular respiration processes?(1 point)
by observing cellular respiration under bright light conditions
by observing cellular respiration only when photosynthesis occurs
by observing cellular respiration by studying biomagnification
by observing cellular respiration under the absence of light
Question: "Scientists are looking to determine the primary productivity of a lake by analyzing its oxygen net primary productivity. How are scientists able to measure how much oxygen is used during a plant’s cellular respiration processes?"
Answer: "Out of all the options given, the best way for scientists to have the chance to measure the usage of oxygen during a plant's cellular respiration processes would be by 'observing cellular respiration under the absence of light'. So, I would say the best option would be Option D. "
To measure how much oxygen is used during a plant’s cellular respiration processes, scientists did by observing cellular respiration in the absence of light, hence option D is correct.
How to measure oxygen level?As a result, in the absence of photosynthesis, there would be no glucose or oxygen for respiration, and since photosynthesis requires carbon dioxide, only anaerobic respiration would be possible.
Examining a lake's oxygen net primary production, researchers hope to ascertain the lake's primary productivity. By monitoring the output of oxygen or the intake of carbon dioxide, primary productivity is typically calculated. The standard unit of measurement for production rates is grams of organic carbon per unit area per unit of time.
Therefore, observing cellular respiration in the absence of light.

Read the article and use the information to answer the question that follows. Nature vs. Nurture Define the terms "nature" and "nurture" in the context of the Nature vs. Nurture controversy.
The correct answer to this open question is the following.
Although you did not include the article or a link to it, we can comment on the following general terms.
The controversy between the two terms in the area of Psychology stems from de debate if the behavior in humans is inherited by the parents or it is acquired when the individual starts to socialize. This means that the two schools of thought are debiting on the idea of if the behavior is learned or if it is the product of the genetic.
So Nature for scientists is the information that is conveyed by genetics and is passed from parents to children. Here, biology and chemistry play a major factor.
On the other hand, Nurture can be understood as environmental factors that the individual is exposed to when it receives the external influence and starts to learn new things and how to react to these external influences.
Answer:
Nature refers to heredity, the genetic makeup of an individual while nurture refers to environmental factors an individual is exposed to in their lifetime.
Describe how an organism's genotypes codes for their phenotype. In your answer use the vocabulary terms: Phenotype, genotype, DNA, mRNA and protein. Please dont answer if you dont know it.
Answer:
The organism's genotype encodes their phenotype because the genotype corresponds to the characteristic that is determined by genes —formed by fragments of DNA— which are transcribed into mRNA to be translated into amino acid sequences in the synthesis of proteins, determining the morphological and functional characteristics of an organism, that is, its phenotype.
Explanation:
Genotype corresponds to the genetic information contained in the DNA, according to the sequence of nucleotides in its molecular structure. This genotype includes characteristics or polymorphisms that define the appearance and function of living beings.
Each DNA molecule constitutes a chromosome, formed by genes —DNA fragments— each of which determines specific characteristics.
When DNA is transcribed into mRNA, information is being sent that is necessary for the incorporation of amino acids into a protein that is being synthesized. The proteins, in turn, determine morphological and functional characteristics that constitute the phenotype of an individual.
