What does a number in front of a molecular formula stand for???????
Explanation:
The small number behind each element symbol designates the number of atoms of each element in a chemical formula. If there is no number, it is assumed there is only one of those elements. A large number designates how many units there are of that compound.
Answer:
Element's number of atoms in a chemical formula
Explanation:
The small number behind each element symbol indicates each element's number of atoms in a chemical formula. If there is no number, it is assumed there is only one of these elements. A huge numeral in front of a compound designates whereby many units there are of that compound.
Need help plz!!! Trying to catch up on biology anything can help!!!!
Answer:
See the answer below
Explanation:
The control group in an experimental study is the subject group that is not administered the treatment variable. The control group forms the baseline for comparing the effects produced by the treatment variable on the experimental group.
Thus, in this case, the control group would be the 10 mice that were not exposed to the radio waves.
The independent or the manipulated variable, in this case, is the exposure or otherwise of the mice to the radio waves.
The dependent variable is the actual variable that is going to be measured, otherwise known as the effect variable. In this case, the dependent variable would be the strength of the mice measured by their ability to push the block of wood blocking their food.
Since 8 out 10 mice and 7 out of 10 mice were able to push the wooden block in both the experimental and the control group, Bart's conclusion should reject the hypothesis that the radio waves make mice extra strong.
Bart's experiment can be improved by increasing the number of subject mice in each group. The more the number of subjects, the more the accuracy of the outcome would be.

The chromosome number in animas is kept the same from one generation to the next because of__.
Answer:
Mitosis
Explanation:
Mitosis is the process of cell division. In this process cells are split to create exact replicas of eachother. It is why we don't grow ears on our hands when they are injured. The hand cells are replicated to create more, so it heals correctly. In the Mitosis the two resulting daughter cells always have the same number of chromosomes from the parent cell. Their role is to maintain the same number of chromosomes in each cell division constant, which allows us to grow and self-maintain our bodies.

What would happen to the amount of glucose and oxygen produced during photosynthesis if the
amount of sunlight decreased? EXPLAIN,
Without enough light, a plant cannot photosynthesize very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
Horizontal moves occur along plate margins
A: True

What would be the correct complimentary DNA strand given the following DNA strand.
DNA: ATACGAAAT (Type as one word - no spaces)
Using the same strand of DNA, what would be the correct sequence for an RNA strand? (Type as one word - no spaces)
Answer:
TATGCTTTA for question 1.
For RNA following the original strand it would be UAUGCUUUA
Explanation:
Replace A with T(vice versa), and C with G(vice versa)
But for the RNA, A bonds with U instead of T. So it would be the same as the complimentary DNA, just with U instead of T

Some people have one sickle cell gene and one normal gene. They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the human system of reproduction result in people getting one copy of a sickle cell gene and one copy of a normal gene? Describe the process.
Answer:
Through meiosis
Please find the description below
Explanation:
Humans reproduce via a type of reproduction called SEXUAL REPRODUCTION. Sexual reproduction is the type of reproduction that involves two sexes (male and female) of an organism. The males produces male gametes called SPERM while females produce female gametes called EGG.
The process by which these gametes is produced is called MEIOSIS. Meiosis is a division that reduces the chromosome number of the parent cells. According to Gregor Mendel, it occurs in such a way only one allele of a gene is present in each gamete.
Hence, according to this question, getting one copy of a sickle cell gene and one copy of a normal gene is as a result of meiotic division of male and female. One parent undergoes meiosis and contributes the normal allele (S) while the other parent undergoes meiosis and contribute the sickle allele (s).
how are energy and matter transferred between organisms and their environment
Answer:
The energy is transferred both to the decomposer (for growth and development) and to the ecosystem (as heat energy).
Explanation:
Answer:
Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. ... Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments.

Your lab is working on sequencing a new plasmid. Before starting, you all decide to guess how many base pairs you think the new plasmid has. The lab members' guesses are 4,005; 4,006; 4,007; and 4,010. It turns out the plasmid has 7,968 base pairs. Accurate Precise Neither Both
Solution :
In this question we have to determine whether the statement given in the question is accurate or precise or both or neither of them.
In the question it is given that the lab members are making a guess about how many base pairs will the new plasmid will have. Their random guesses of base pairs are 4,005; 4,006; 4,007; and 4,010. But in actual, the new plasmid has 7,968 number of base pairs.
Therefore, according to it, the data in the statement is precise but it is not accurate.
Precision refers to the degree of the reproducibility of measurements even if the values varies from accepted values. And accuracy shows how much close the measurement is to the accepted or the known value.
We say that we have a precise data on our hands and not an accurate one
Option B
AccuracyQuestion Parameters:
The lab members' guesses are 4,005; 4,006; 4,007; and 4,010.
Generally, accuracy shows how close a size is to a regarded or established value, whilst precision in facts capability the degree of reproducibility of the measurements. Measurements that are each specific and correct are repeatable and very close to genuine values.
Hence, we say that we have a precise data on our hands and not an accurate one
Option B

Primary producers are the basis of any food chain. Sunlight powers photosynthesis which results in the production of chemical energy, glucose. Some organisms are known to survive in dark habits in which sunlight cannot penetrate. What process is responsible for how these organisms obtain energy? A) chemosynthesis B) photosynthesis C) Spermatogenesis D) Cellular respiration
Answer:
A) Chemosynthesis
Explanation:
Organisms, such as bacteria and other living organisms, use chemosynthesis when there is an absence of light. They use inorganic chemicals to produce energy through reactions.

Which is NOT true about the macromolecule pictured?
Pls help lol
Answer:
C i think
Explanation:
The hydrophobic effect is related to the fact that water is most stable when it has the most hydrogen bonds and that nonpolar molecules decrease the number of those bonds. True or false
Answer:
True
Explanation:
When a hydrophobe is dropped in an aqueous medium, hydrogen bonds between water molecules will be broken to make room for the hydrophobe; however, water molecules do not react with hydrophobe. This is considered an endothermic reaction, because when bonds are broken heat is put into the system. The hydrophobic effect is considered to be the major driving force for the folding of globular proteins. It results in the burial of the hydrophobic residues in the core of the protein. It is exemplified by the fact that oil and water do not mix and was described well by G. S. Hartley in 1936. 1 Hydrophobic effect. The hydrophobic effect increases the thermodynamic activity of large hydrophobic molecules of metal complexes formed in the aqueous phase of solvent extraction systems, which promotes their transfer from the aqueous to the organic phase.
