What was one conflict that was resolved in the resolution?
The characters learned to respect each other enough to discuss why the boy tried to grab the purse.
Mrs. Jones took care of the boy's hunger.
The boy asked for the money to buy shoes.
Mrs. Jones taught the boy to have manners.
The answer is the boy asked for money
Answer:
The characters learned to respect each other enough to discuss why the boy tried to grab the purse.
Explanation:
In the short story "Thank You, Ma'am" by Langston Hughes, a young, hungry boy was about to rob a woman of her purse. But as circumstances would turn out, he was unsuccessful in that attempt but then learned a valuable lesson from the very woman he had targeted.
One conflict that was resolved in the resolution was that both of the characters, Mrs. Luella Bates Washington Jones and Roger, learned to respect one another. By her act of inviting him to her home and preparing food for him, Roger also came to respect and trust the woman. It was this faith that helped them discuss the events that led to Roger's failed attempt of robbing Mrs. Jones, and Roger left the house with a sense of appreciation and a change of heart.
Thus, the correct answer is the first option.

what is an outcome of lack of oxygen?
Answer:
Blood carries oxygen to the cells throughout your body to keep them healthy. Explanation:
Hypoxemia can cause mild problems such as headaches and shortness of breath. In severe cases, it can interfere with heart and brain function. Hypoxemia that causes low oxygen levels in your body's tissues is called hypoxia.
The outcome of lack of oxygen To maintain your body's cells healthy, blood provides oxygen to every cell.
What is cell ?The smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. The cell membrane, the nucleus, and the cytoplasm are the three primary components of a cell. The substances that enter and leave the cell are governed by the cell membrane, which encloses the cell.
There are two different types of cells: prokaryotic cells, which lack a nucleus but still have a nucleoid area, and eukaryotic cells, which have a nucleus. Eukaryotes can either be single-celled or multicellular, in contrast to prokaryotes, which are single-celled organisms.
From bacteria to humans, cells give all living things their structure and functionality. They are regarded as the tiniest form of life by scientists.
Thus, To maintain your body's cells healthy, blood provides oxygen to every cell.

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.

Some genes are important enough to be called "molecular switch" or "master" genes. What is the purpose of these genes?
A. They control when other genes are expressed
B. They determine the organization of the genome
C. They regulate cell metabolism
D. They modulate the rate of translation
Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
B. Master genes do not determine the organization of the genome .
C. Regulation of cell metabolism depends of substances as hormones and enzymes.
D. The rate of translation does not depend on the activity of master genes.
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.
A student is presented with a model of a digestive system and is asked to remove one structure (small or large organ) that will have the largest impact on decreasing chemical digestion. Which structure should the student remove
Answer:
Small intestine
Explanation:
Digestion is the process of breaking down food molecules into simpler and usable forms by the body cells. The process of digestion involved the mechanical aspect and chemical aspect. The mechanical one deals with using physical means like chewing to break down the food particles.
However, the chemical one deals with the usage of chemically-secreted enzymes to work on the food molecules. Lots of digestive organs are involved in this chemical digestion, but, the most of chemical digestion takes place in the SMALL INTESTINE. The small intestine is where most of the chemical digestion occurs including absorption.
Hence, according to this question, the student should remove the SMALL INTESTINE because it will have the largest impact on decreasing chemical digestion.
In silkworms,yellow cocoon (B) is dominat over white cocoon(b). If the mom is BB and the dad is bb, what are the chances they have offspring with yellow cocoons?
Answer:
100 %
Explanation:
Dominance is a genetic phenomenon where a gene variant or allele masks the effects of another allele (of the same gene) in heterozygous individuals. This last gene variant is referred to as the recessive allele. In this case, the silkworm mother can produce only one type of gamete carrying the dominant gene (B) form, while the silkworm father can produce only one type of gamete carrying the recessive gene (b) form. In consequence, from this cross, all offspring (100 %) will be heterozygous (Bb) and therefore they will express the dominant trait (i.e., yellow cocoon).

When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between which two reservoirs of the carbon cycle? * A. Hydrosphere and biosphere B. Geosphere/lithosphere and atmosphere C. Atmosphere and biosphere D. Hydrosphere and geosphere/lithosphere
Answer:
B
Explanation:
When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between the Geosphere/lithosphere and the atmosphere.
Both the geosphere and the atmosphere represent important reservoirs of carbon. The digging-up of fossil fuels, otherwise known as exploration, is carried out in the geosphere or the lithosphere part of the earth. For example, crude oil is obtained deep from the ground. When the fuels are burned, they release carbon in the form of carbon dioxide into the atmosphere.
Hence, it can be concluded that carbon flows from the geosphere/lithosphere part of the earth to the atmospheric portion of the earth when fossil fuels are burned.
The correct option is B.

Explanation:
Why does the body produce more urine on a cold day rather than a hot day if the same amount of
water is consumed?
Explanation:
During summer when the surrounding temperature is high, we lose water in the form of sweat, direct evaporation considerably. Hence kidneys retain water for maintaining fluidity of the blood and less urine is formed.
But during winter, the surrounding temperature will be very low. There will not be any sweating, no evaporation losses. Moreover to keep the body temperature constant, the blood capillaries in the skin get constricted and the blood pressure is increased. The result is that our body gets warmed up. In order to maintain the blood pressure normal, the excess water along with the wastes is excreted mostly in the form of urine. This is the reason for more urine out put and frequent urination under very cool conditions and in winter.

In a plant species, the allele for dark green leaves (D) is dominant over the allele for light green leaves (d). A plant with Genotype (Dd) is crossed with a plant with genotype (did). What percentage of the offspring are expected to be hybrid for the leaf color trait. A 0% B 25%. C.50%. D 75%
The percentage of the offspring that is expected to be hybrid for the leaf color trait is 50%. The correct option is C.
What are alleles?The trait is caused by a pair of two alleles on the chromosome, and there are two possible outcomes. The dominant allele, which is typically written in capital letters and will control the organism's phenotype even in the presence of the other allele, is the one that has the ability to silence the other allele.
It is used in biology to refer to inherited traits that do not manifest in the phenotype of the individual who possesses them but may do so in their offspring.
Recessive alleles, which are only expressed when they are homozygous, are this other type of allele. Both heterozygous and homozygous genotypes exhibit the dominant allele.
Dd is crossed by dd.
100 / 2 = 50%.
Therefore, the correct option is C.

Explanation:
Weak hydrogen bonds between the nitrogenous base pairs hold the two strands of DNA together. Why are the strands held together by weak hydrogen bonds instead of covalent bonds
Answer:
Explanation:
Hydrogen bonding is usually occur wen interaction with hydrogen atoms occur.
Hydrogen bonds joins DNA polymers because an hydrogen atom occur on on one base which is called hydrogen bond donors and another oxygen or nitrogen atoms on the base across from it which is called hydrogen bond acceptors.
Adenine “A” a purine and Thymine “T” a pyrimidine each have a donor and one acceptor, whereas Cytosine “C” a pyrimidine has one donor and two acceptors, and Guanine “G” a purine has one acceptor and two donors.
This atoms allows for hydrogen bond between them that gives them structure of DNA molecule.
A nucleotides is hydrogen bonded to T nucleotides while C nucleotides is hydrogen bonded to G nucleotide this is called complementary base pairing.
