observe the given relation and fill in the blanks cucumber: tendril citrus: meiosis: reduction division mitosis:
Answer:
citrus: thorns
mitosis: equational division
Explanation:
From the relationship:
Tendrils are thread-like appendages found in most climbing plants. They primarily function as supporting organs for climbing plants (such as cucumber) by stretching out and twinning around physical supports. The equivalence of this in citrus is the thorn.
Meiosis is a reductional cell division in which the chromosome number of the daughter cells is half of that of the other cells. Mitosis is equational division because the chromosome number of the parent cell is the same as that of daughter cells.

A man with Type B blood has children with a woman with type A blood. Their children have the following blood types, A, AB, B, and O. What are the genotypes of the parents? What would be the genotypes of the parents if the offspring could only have type AB or A blood
the child has the blood type of Ab its obvious
Explanation:
only when both alleles is O, the blood group can be O. Thus both parents must have O as one allele
Thus man's genotype: BO or
[tex] { | }^{b} i[/tex]
Woman's genotype : AO or
[tex] { | }^{a} i[/tex]
When
the children can not have O blood
The children cannot have B blood
means the man have BO
[tex] { | }^{b} i[/tex]
and woman have AA
[tex] { | }^{a} { | }^{a} [/tex]
Because
if man have BB, and woman have AA
children can only have AB
if man have BB, and woman have AO
children can only have AB and B

punto de vista sobre la ley de mendel
Answer:
Las leyes de Mendel son leyes que describen la herencia de rasgos hereditarios. Las leyes forman la base de la genética clásica. Asumen que cada individuo posee dos alelos para el mismo rasgo y los recibe al azar de los cuatro alelos diferentes de los padres. El fenotipo (apariencia física) del individuo depende de cuál de los dos alelos es dominante y cuál es recesivo. Dado que los individuos pueden transmitir ambos alelos a su descendencia, la descendencia incluye tanto individuos con fenotipo dominante como recesivo.

The sacrum articulates with the The sacrum articulates with the ilium and ischium. pubis. ilium. ischium and pubis. ischium.
Answer:
The sacrum articulates with the ilium.
Explanation:
The sacrum is a bone formed by the sacral vertebrae, which have fused to give this bone. Above it articulates with the lumbar vertebra, below with the coccyx, which is the last section of the vertebrae column. Lastly, it articulates with the ilium at the sides. The ilium is one of the three bones that makes the hip bone. It is the largest one and in the upper part of the hip bone.
The ischium and pubis, which are the other two bones that form the hip bone, do not articulate with the sacrum, but they articulate with the ilium and with each other.

The DNA of a prokaryote is arranged in a single coiled chromosome located in a region called the ____________ . Some prokaryotes carry genes on extrachromosomal pieces of circular DNA called ____________ .
Answer:
1. Nucleoid
2. Plasmid
Explanation:
Prokaryotes are groups of organisms characterized by the lack of a membrane-bound nucleus in their cell. Due to this, the genetic material (DNA) of prokaryotes are found naked i.e. not housed. The DNA of a prokaryote is arranged in a single coiled chromosome located in a region of the cell called NUCLEOID.
However, some prokaryotes e.g. bacteria carry genes on extrachromosomal pieces of circular DNA called PLASMID. Plasmids carry certain genes like antibiotic resistance genes.

There is a new trend to focus on dopamine receptor sensitivity rather than on dopamine itself because
Answer:
There is no scientific evidence to prove that people with schizophrenia ingest dopamine capable of accumulating excess in the body.
Explanation:
Although you did not specify that your question is associated with the origin of schizophrenia in people, we can see that this is the main topic of your question, due to its context. This is because scientists have been striving to find the origin of this disease, in order to be able to combat it in the early stages. Although many scientists believe that the origin of this disease is associated with excessive intake of dopamine, there is not strong enough scientific evidence to show that this is true. Because of this lack of evidence, filmmakers have focused on associating the origin of the disease with the sensitivity of the dopamine receptor and not with the dopain itself.

Organisms use glucose to store and transport energy.
True
False
Answer:
Glucose and ATP are used for energy by nearly all living things. Glucose is used to store and transport energy, and ATP is used to power life processes inside cells. Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose.
Explanation:
Most organisms use glucose and ATP for energy. ATP powers cells, and glucose stores and transports energy. Photosynthesis converts sunlight into glucose for many autotrophs.
What do organisms use to store and transport energy?All living things use ATP and glucose as energy sources. Energy is stored and transported by glucose, and cellular life functions are powered by ATP. Through the process of photosynthesis, which converts solar light energy into chemical energy that is stored in glucose, many autotrophs produce food.
Glycogen is the name given to this form of glucose that is stored and is composed of several linked glucose molecules. Glycogen is broken down to release glucose into the bloodstream, which is then used as fuel for the cells, when the body needs a sudden surge of energy or when the body isn't obtaining glucose from food.

A Scientist discovers a chemical that she thinks might be a potential treatment for a certain type of cancer cell. In order to test her hypothesis, the scientist treats one plate of cancerous cells with the newly discovered chemical, and leaves another plate of cancerous cells untreated. After 7 days, the scientist measures the number of living cells in each plate. The scientist finds that the cells treated with the chemical have a lower survival rate than cells left untreated. The scientist further observes that the substance has an effect on the Rough endoplasmic reticulum (RER). How might disabling the rough ER potentially hurt the cancerous cells? Be specific in your answer. What is the dependent variable? What is the independent variable?
Answer:
Affecting the ER causes alteration in cell homeostasis and eventual death.Independent variable: Drug or chemicalDependent variable: Cancer cells survival.Explanation:
Hypothesis ⇒ A chemical ⇒ might be a potential treatment for cancer cells.
Experiment:
Treated ⇒ One plate of cancerous cells with the new chemicalUntreated ⇒ Another plate of cancerous cells with no chemical7 days later ⇒ the number of cells in each plate
Results:
Cells treated with the chemical have a lower survival rate than cells left untreated.
Treated plate ⇒ fewer cellsUntreated plate ⇒ more cellsChemical affects the Rough endoplasmic reticulum (RER)
----------------------------------------------------------------------------------------------------------
The endoplasmic reticulum is in charge of many cellular functions, such as protein folding, maturation, and transport, especially those destined for secretion. It produces the latest protein modifications after transduction.
When the synthesizing protein gets in the Rough endoplasmic reticulum, it continues its building in the organelle. Finally, the protein suffers folding and the initial stages of glycosylation.
Once the protein synthesis in the endoplasmic reticulum is over, these molecules are packaged into vesicles and sent to the Golgi complex for their final association with carbohydrates. Finally, protein leaves the Golgi complex and goes to its final destiny.
Any alteration in the intracellular environment
inevitably affects the organelle and its functions. When the organelle is not properly working, proteins synthesis is affected and, consequently, all the cellular activities. The affected cell homeostasis might be so altered that the cell ends dying.
If the drug affects the ER by altering its environment or directly affecting it, the organelle will fail to perform its functions, and the cell will eventually dye.

The independent and the dependent variables are the two principal factors needed in an experiment.
Independent variable: Refers to all the variables in an experiment that provoke a response in another variable. The independent variable changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter.
In the exposed example, the independent variable is the drug that affects the cancer cells. The researcher decides to apply it or not, and the concentrations in which the drug is.
Dependent variable: Refers to the variable that reacts to the changes produced in the independent variable. Depending on how the independent variable is modified, the dependent variable change. It is usually identified by the letter Y.
In the exposed example cell survival is the dependent variable. Cancer cells respond to the presence/absence of the chemical, and might differently respond to the varying concentration of the drug.
