Answer:
The correct answer is option C. Epstein-Barr virus: virus visible inside red blood cells.
Explanation:
The Epstein-Barr virus is a virus or virions that cause several serious diseases such as Guillain-Barre syndrome and kind of cancers. These viruses can be detected by the making smear of blood in the electron microscope.
The electron microscope shows round capsids that have protein encased genetically material that is loosely enclosed in a membrane. These are transmitted through saliva generally.
Thus, the correct answer is C.
Answer: D.Arrows point away from the positive.
Why?
Arrows point away from the positive charge and toward the
negative charge.
Explanation:
Suppose that you rubbed a balloon with a sample of animal fur such as a wool sweater or even your own hair. The balloon would likely become charged and its charge would exert a strange influence upon other objects in its vicinity. If some small bits of paper were placed upon a table and the balloon were brought near and held above the paper bits, then the presence of the charged balloon might create a sufficient attraction for the paper bits to raise them off the table. This influence - known as an electric force - occurs even when the charged balloon is held some distance away from the paper bits. The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects. One goal of this unit of The Physics Classroom is to understand the nature of the electric force. In this part of Lesson 1, two simple and fundamental statements will be made and explained about the nature of the electric force.
Perhaps you have heard it said so many times that it sounds like a cliché.
Opposites attract. And likes repel.
These two fundamental principles of charge interactions will be used throughout the unit to explain the vast array of static electricity phenomena. As mentioned in the previous section of Lesson 1, there are two types of electrically charged objects - those that contain more protons than electrons and are said to be positively charged and those that contain less protons than electrons and are said to be negatively charged. These two types of electrical charges - positive and negative - are said to be opposite types of charge. And consistent with our fundamental principle of charge interaction, a positively charged object will attract a negatively charged object. Oppositely charged objects will exert an attractive influence upon each other. In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart. Similarly, a negatively charged object will exert a repulsive force upon a second negatively charged object. Objects with like charge repel each other.
Answer: B
Details: This is because when a reactant is added equilibrium must shift to the right to produce more product to balance out.
It’s not so much that the alleles separate but more so that only one of the parental alleles is passed on. Let’s look at a monohybrid trait to make this easier to comprehend, and let’s say the trait is eye color. One of the parents has blue eyes, a recessive eye color, meaning both of their alleles for that trait are recessive. However, the other parent has brown eyes, a dominant eye color, meaning this parent could either possess one dominant allele that hides the recessive blue (let’s just limit it to two colors to avoid confusion) or they could have two dominant alleles. When gametes are formed, they consist of a combo of alleles, one maternal and one paternal. Meaning, in the case of the heterozygous dominant parent (or the parent with one dominant and one recessive allele) they could either pass on their dominant allele, giving the child brown eyes, or their recessive allele, giving the child blue eyes because they can only ever inherit the recessive trait from the other parent. The law of segregation essentially says that a parent cannot clone itself and create a child in its exact image but rather that the child would inherit one trait from each parent. This is why the child has two alleles for the trait and the parents both have two alleles for this trait. Hope this helps (:
Answer:
Embryonic stem cells could be used to make more specialized tissues that have been lost to disease and injury. For tissues that are constantly replaced, like blood and skin, stem cells would probably be replaced directly. ... Embryonic stem cells could be grown into more specialized cells for screening potential drugs.
