A. Bb, bb
B. BB, bb
C. BB,BB
D. Bb,BB
I think its Bb, bb because if julie has blonde hair then it's most likely to be Bb, bb
If Julie has blonde hair, the genotypes of their parents could have been found to be Bb and bb. Thus, the correct option for this question is A.
What do you mean by Genotypes?Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for specific studies in order to express some genetic characteristics.
According to the context of this question, if the trait of Blonde hair is recessive in nature. This means that both the alleles of this gene are recessive, i.e. bb.
Now, if Julie has blonde hair, which means both alleles are recessive. So, the genotypes of parents of Julie are either homozygous recessive or heterozygous in nature. This characteristic is well determined by option 1.
Therefore, if Julie has blonde hair, the genotypes of their parents could have been found to be Bb and bb. Thus, the correct option for this question is A.

Natural selection states that complex organisms evolved through random mutations alone. True or False?
Answer:
False.
Explanation:
This statement is false because organisms don't evolve - populations do. New gene variants (i.e., alleles) are produced by random mutation, and over the course of many generations, natural selection may favor advantageous variants, causing them to become more common in the population. However, because mutation rates are low relative to population growth in most species, mutation alone doesn't have much of an effect on evolution.

TLRs are Group of answer choices the coatings of pathogens by complement. present in intact skin, sebum, tears, etc. phagocyte receptors that detect PAMPs. nonspecific leukocytes that secrete toxins onto the surface of virally infected cells. molecules that damage cells, resulting in cell lysis.
Answer: Phagocyte receptors that detect PAMPs
Explanation:
TLRs or Toll-like receptors, are a family of proteins that are part of the innate immune system. TLRs are transmembranous and recognize pathogen-associated molecular patterns (PAMPs), which are groups of chemical characteristics common to certain types of pathogens. Patterns detected by TLRs include lipopolysaccharide, a compound found on the surfaces of Gram-negative bacteria, and double-stranded RNA, which is an integral part of the life cycles of many viruses. These PAMPs are generally important for the survival of the pathogen, so they are well preserved. Activation of these receptors induces inflammatory responses in leukocytes of myeloid lineage, signaling via NF-κB, which is a transcription factor that activates pro-inflammatory genes. Activated TLRs also increase the production of co-stimulatory molecules such as CD80, CD86 and CD40. These proteins, expressed on the surface of antigen-presenting cells, are necessary for the activation of T-lymphocytes by dentritic cells and macrophages already showing antigens in their MHC type II molecules (Major Histocompatibility Complex, they participate in the presentation of antigens to T lymphocytes)
In addition, TLR-mediated signaling on antigen-presenting cells (APCs) plays an important role in linking the innate and adaptive immune responses.

what is cardiovascular arrest...?
explain...?
Answer:
Cardiac arrest is the abrupt loss of heart function in a person who may or may not have been diagnosed with heart disease. It can come on suddenly, or in the wake of other symptoms. Cardiac arrest is often fatal, if appropriate steps aren’t taken immediately.
Each year in the United States, more than 350,000 cardiac arrests occur outside of a hospital setting.
These two distinct heart conditions are linked. Sudden cardiac arrest can occur after a heart attack, or during recovery. Heart attacks increase the risk for sudden cardiac arrest. Most heart attacks do not lead to sudden cardiac arrest. But when sudden cardiac arrest occurs, heart attack is a common cause. Other heart conditions may also disrupt the heart’s rhythm and lead to sudden cardiac arrest. These include a thickened heart muscle (cardiomyopathy), heart failure, arrhythmias, particularly ventricular fibrillation, and long Q-T syndrome.
Cardiac arrest is reversible in most victims if it's treated within a few minutes. First, call 911 for emergency medical services. Then get an automated external defibrillator if one is available and use it as soon as it arrives. Begin CPR immediately and continue until professional emergency medical services arrive. If two people are available to help, one should begin CPR immediately while the other calls 911 and finds an AED.
Sudden cardiac arrest is a leading cause of death – over 320,000 out-of-hospital cardiac arrests occur annually in the United States. By performing Hands-Only CPR to the beat of the classic disco song “Stayin’ Alive,” you can double or even triple a victim’s chance of survival.

The human genome project identified the sequence of base pairs in human DNA and identified several genes. Which question would least likely lead to a scientific investigation based on these findings? Answers: Are certain humans more likely to develop genetic diseases? How can DNA be used to identify criminals? Can drugs be developed to target certain genes? Should there be laws to protect DNA information?
Answer:
I believe the correct answer is "How can DNA be used to identify criminals?".
Explanation:
The question asks to pick the question that is least likely to lead to a scientific investigation based on these findings. The question states that the HGP identified sequences of base pairs in human DNA as well as many genes. The other questions were very likely to have arisen bases off of these findings. Criminal identification based on DNA is not the focus of the Human Genome Project.
Which option identifies ways that people positively affect Earth’s resources?
Answer:
c is the correct answer on EDGE2020
There are many ways by which humans can positively impact Earth's resources. These include reforestation, reducing pollution, protection of endangered species, and mindful use of water and attempts to replenish the water bodies, etc.
What are the earth's resources?The resources present on earth which were not formed due to any kind of human intervention are called earth's resources or earth's natural resources. There are various natural resources found on earth.
Energy resources like petroleum and natural gas, metallic resources like iron, copper, and gold, and nonmetallic resources like granite, sandstone, etc are some of the examples of various resources found on earth.
However, due to the rise in consumerism, these resources are being overexploited by humans which have resulted in their depletion.
But, the awareness of this is spreading fast and humans have adopted various measures to prevent negative impacts and induce positive impacts on the resources of the earth.
Therefore, humans can have a positive impact on Earth's resources.

Consider a system in which low levels of protein "Q" triggers production of hormone A. The reaction of target cells of hormone A is to produce and release hormone B, which stimulates production of hormone C. In response to hormone C, the target cells up-regulate protein Q. In this scenario we see an example of _____.
Answer:
Negative feedback
Explanation:
Negative feedback is produced when a mechanism is amplified through an inverse loop, which tends to reduce the fluctuations in the system. In this case, the negative feedback mechanism represents a homeostatic response of the body where the release of a target hormone (hormone C) decreases in response to the increase of a protein (protein Q) upstream in the signaling pathway. Therefore, in this scenario, it is expected that negative feedback causes a decrease in hormone function.
When human skin suffers a cut, the process of healing rapidly begins allowing for wound closure and healing within a few days. Keloids occur when skin around wounds continues to grow after the skin has healed. A disruption in the regulation of which cellular process is probably responsible for this condition
Options
A. Mitosis
B. Meiosis
C. Apoptosis
D. Phagocytosis
Answer:
A
Explanation:
Mitosis is a type of cell division which takes place in living organism during growth and development.Therefore it is ensures the regenerations of cells and tissues during healing.
Therefore the restoration of new cells to the skin following injuries is due to mitosis.Since this is a multiplication division(2n) in which the daughter cells are exactly like the parents' cells the new tissues of the skin by mitosis, look exactly like the previous one that was injured.
In cases where the mitotic growth control is lost, the scare tissues of the injured part overgrows with granulation tissues and this leads to Kaloids.
Its is a mass of Collagen Type 1.(Collagen is an fibrous proteins which has largest proportion in mammals).
Keloids is characterized with pink or red coloration and elevation of the area,excessive growth of the area, with irritating patch skin
What are emergent properties?
Answer:
Emerging properties may arise by transient interactions such as individual organisms building a population. Human interaction in populations leads to the emergence of language, poetry, musical composition, and art. When populations of different species interact, communities form. Many emergent properties are the result of interactions between species in communities.
Emergent properties are characteristics of a system that do not exist in any of its constituent parts individually but originate as a result of interactions between those parts.
What does the characters indicate at ?These characteristics are frequently intricate and challenging to forecast. Emergent characteristics are a crucial idea in several disciplines, including physics, chemistry, and biology.
Emergent qualities in biology can be observed in an organism's behaviour. For instance, a flock of birds' behaviour is an emergent characteristic of the individual birds that make up the flock.
The behaviour of the flock is a product of interactions among the individual birds and is not exhibited by any one individual bird. Similar to this, a school of fish's behaviour is an emergent characteristic of each fish.
Emergent features in chemistry can be observed in how molecules behave. An emergent attribute of a substance's individual molecules, for instance, is the substance's boiling point. The boiling point is not a property of any one molecule, but rather the outcome of interactions between the molecules.
Particle behaviour in physics exhibits emergent features. An emergent attribute of a material's individual particles, for instance, is the material's electrical conductivity.
The interactions between the individual particles produce the electrical conductivity, which is not a property of any one of the individual particles. As a result, emergent properties are characteristics of a system that develop.

1.What is meant by Plasma therapy ? Is it a remedial treatment for Coronavirus? Express your answer with valid points
Answer:
It is a therapy that involves the use of plasma from recovered patients (which is composed of antibodies against the virus)
Explanation:
The immune system of patients already recovered from viral diseases naturally generates defensive molecules that circulate in the blood. These molecules are known as 'antibodies', and they are localized in the plasma of the blood, which is composed of coagulation factors, albumin, fibrinogen and, of course, antibodies. These antibodies bind to specific viral antigens in order to promote their neutralization and destruction. In consequence, the plasma from recovered patients contains particular antibodies that may be used to treat specific diseases.
