Answer:
Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.
Explanation:
Transcription Initiation. The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5′) of the gene at a specialized sequence called a promoter (Figure 2a). In bacteria, promoters are usually composed of three sequence elements, whereas in eukaryotes, there are as many as seven elements ...

Binary fission and mitotic cell division is the same true or false
Answer:
Answer false have a blessed night
All cells divide and reproduce the same way ... true or false explanation needed
Answer:
False
Explanation:
False because cells can reproduce in two ways. Mitosis, the process of making new body cells or cell division. OR Meiosis where there is genetic information transfered between cells such as how humans are made.
All cells do not divide and reproduce the same way since there are two methods for cells to divide. So, the given statement is False.
What is Cell division?The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle. Usually, cell division happens as part of a longer cell cycle where the DNA is reproduced as the cell nucleus divides during cell division.
Meiosis and mitosis are the two processes through which cells can reproduce. The process of creating new body cells, or mitosis, differs from meiosis, which is the process by which genetic material is passed between cells, as in the creation of humans. Thus, not all cells divide and reproduce in the same way.
Therefore, the given statement is False.

The white blood cell is attracted to the bacteria because proteins called antibodies have marked the bacteria for destruction. These antibodies are specific for disease-causing bacteria and viruses. When the white blood cell catches the bacteria it goes about "eating" it in a process called phagocytosis.

A 100 kg box is initially at rest on a level surface. One 10 N force acts on the box , directed toward the right. A second 10 N force acts simultaneously on the box , directed toward the left , as shown.
Since 10 N forces are acting from both sides, these are balanced forces and the box will not move because balanced forces are acting on it. So the correct option is D.
What are balanced forces?Forces that are equal in magnitude and opposing in direction are said to be balanced forces. Equilibrium is seen as a condition of balanced forces. There is no shift in direction when the forces are in balance.
Balanced combined forces have always been equal to zero. These are vectors for merging. Balance forces cannot alter an object's momentum or direction.
An item is kept traveling at a constant speed by a balanced force. In it, Newton's First Law of Motion is explained. A good illustration of a balanced force is a book on the table. The normal force (support force) of the table balances out the weight of the book. The two forces are exactly equal and opposed to one another.
While forces that are balanced can keep an item at rest or move at a steady speed, unequal forces can cause things to accelerate.
Therefore the correct option is D.

apparatus?
Digestion of macromolecules and old organelles
Detoxification of poisonous molecules within the cell
Harvesting of energy from organic molecules to make ATP
Processing and packaging of cellular materials prior to export
Answer:
Processing and packaging of cellular materials prior to export
Explanation:
Our cells contain many different organelles. Every organelle has its own function, just like every organ in our bodies.
The Golgi apparatus is one of these organelles. It can be found in most eukaryotic cells. Its purpose is to transport, modify, and package proteins and lipids before they're delivered to other parts of the body. This is the function the organelle with smooth-sided channels Megan is observing would need to perform in order to be identified as the Golgi apparatus.

The figure shows DNA replication.
Answer:
The figure shows where mitosis occurs in the cell cycle. after the interphase
Explanation:
The figure explains where mitosis occurs in the cell cycle, which is present in the third option. The cell cycle is depicted in the diagram, in which different stages are present, such as from the growth stage to the division phase.
What is the role of the cell cycle?The cell cycle is important for cell growth and division, such as the formation of gametes, the cell's growth from its original size to a larger one, the growth of body's size, and so on. The first phase of the cell cycle is the G1 phase, where the cell grows in size, and later in the S phase, DNA replication takes place. In the given image, the cell cycle is depicted with all of these stages, and after the S phase, the G2 phase takes place, and then mitosis takes place in the M phase.
Hence, the figure explains where mitosis occurs in the cell cycle, which is present in the third option.

B. a repulsive force that acts between all objects without contact
C. an attractive force that acts between all objects without contact
D. an attractive force that acts between all objects through contact
Answer:
C. an attractive force that acts between all objects without contact
Explanation:
The force of gravity, first discovered by Isaac Newton, is one of the four fundamental forces. It is a force that is always attractive, and it is exerted between all objects that have mass. Also, the force is exerted even when the two objects are not in contact.
The magnitude of the force of gravity between two objects is given by

G is the gravitational constant

In Labrador dogsblack fur (B) is dominant over golden fur (b). If you cross two heterozygous parents, what percent of offsprings will have golden fur?
Answer:
25%
Explanation:
This question involves a single gene coding for fur color in Labrador dogs. The allele for black fur (B) is dominant over the allele for golden fur (b). This means that a heterozygous dog (Bb) will have a black fur.
According to this question, if two heterozygous parents are crossed i.e. Bb × Bb, the following gametes will be produced by each parent: B and b. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Black fur (BB, Bb) = 3/4
Golden fur (bb) = 1/4
Hence, the percentage of offsprings that will have golden fur is 1/4 × 100 = 25%.
