Alberto created a graph to illustrate his trip. Answer the questions below.
A. How does Alberto's motion change at point B?
B. What is Alberto's speed from point C to point D?
C. What happens at point D? (1 point)
Question 2
Answer the question below about Smokey The Mouse.
A. Use inertia to explain how a balanced force will affect his motion. (Newton's 1st Law)
B. What are two ways Smoky can increase his speed? (Use Newton's 2nd Law to help you)
C. What is an example of an action and reaction at work in this picture? (Use Newton's 3rd Law to help you)
The mouse exerts a force on the ground and the ground exerts an equal and opposite reaction force on the mouse.
At point B, Alberto's distance covered increases with time, equal distance is covered in equal time interval. The speed increases uniformly. At the point C to D, the distance covered with time remains the same. At the point D, equal distance is no longer covered in equal time intervals.
According to the law of inertia, an object will remain at rest or in a state of uniform motion unless it is acted upon by an unbalanced force. This means that smokey mouse will continue moving uniformly unless a force acts on it.
From Newton's second law; F = ma and a = F/m. F = force , m= mass, a = acceleration. This implies that smokey mouse can increase its speed by;
Increasing the force acting on the mouseDecreasing the mass of the mouseAction and reaction is encountered as the mouse is walking. The mouse exerts a force on the ground and the ground exerts an equal and opposite reaction force on the mouse.

Why can't humans regrow limbs?
Answer:In fact, most of our organs have some turnover in cells, which explains why they're younger than our biological age. The human heart, skin, intestines, and even our bones are slowly replaced over time, meaning that a limited amount of damage can be reduced. However, this doesn't extend to limbs.
Explanation:
Answer:
Humans have stem cells, but they aren't readily available to assist in healing. Because most other mammals are similar, they aren't very good at regeneration. Amphibians and some fish have more readily available stem cells, which are usually rather good at regeneration.(please mark brainliest <3)

what factors do you predict might influence the likelihood of mutations occurring in viruses?
The factors which might influence the likelihood of mutations occurring in
viruses is Spontaneous nucleic acid damage and replication inhibition.
Viruses are pathogenic micro-organisms which mutate rapidly than the
humans do. Its ability to mutate very rapidly inside the host cells is what
makes it unique and deadly.
Factors which might influence mutations in Virus include nucleic acid
damage and replication inhibition. When this occurs, the virus isn't able to
mutate thereby causing less damage to the host.

The primary function of the stomach is which of the following?
To serve a holding tank is a primary function of the stomach.
What is Stomach?
The J-shaped organ that digests food is the stomach. It generates acids and enzymes, which are molecules that cause chemical reactions (digestive juices).
Food is broken down by this mixture of enzymes and digestive juices so that it may move to our small intestine.
A portion of the gastrointestinal (GI) tract includes your stomach. Your mouth is the beginning of the GI tract, which is a long tube. The stool (poop) exits your body through your anus. A crucial component of your digestive system is the GI tract.
Therefore, To serve a holding tank is a primary function of the stomach.

Describe the structures within cells that govern heredity, and describe where they are located. Make sure to have 5 sentences which have to be all on topic use great grammar along with great vocabulary usage.
!!PLEASE ANSWER CORRECTLY!!
Answer:
The structure that is responsible for the governance of a cell is the DNA, which is located in the nucleus of the cell.
Explanation:
DNA: It is the genetic material containing genetic information.It is present in the chromosomes inside the nucleus. The genetic information of DNA is stored as code in the four nucleobases namely Adenine, Guanine, Cytosine, and Thymine. The most unique feature of the DNA is that it is self-replicated and makes similar copies of itself. DNA is a double helical structure found in all living organisms including some viruses.In Eukaryotes along with the nucleus, DNA is also present in Mitochondria and Chloroplasts.For more information:

evaluate the statements below and determine which is the best reason that bacterial cells use operons and polycistronic rna.
Given what we know about bacterial cells and their genetic mechanisms we can confirm that they use operons and polycistronic RNA for efficiency.
Bacterial cells are vastly different from human or animal cells. Some of these differences include:
Lack of compact DNALack of organelle surrounded by plasmatic membranesThey have cell wallsMay possess flagellaand many others.
Among these differences is the way in which they encode for the proteins the bacteria will produce. Unlike human cells, bacteria use polycistronic RNA. Where a human strand of mRNA will carry the genetic message to create one protein, the polycistronic mRNA of a bacterial cell will provide the information necessary to create multiple distinct proteins.
Bacteria use this in conjunction with operons, to create very efficient protein manufacturing processes. Operons are sections of DNA in which proteins with similar functions are grouped together in order to make it easier to create the polycistronic mRNA strands.

The ligand that activates the g-protein linked receptor is:
Answer:
When a ligand binds to the GPCR it causes a conformational change in the GPCR, which allows it to act as a guanine nucleotide exchange factor (GEF). The GPCR can then activate an associated G protein by exchanging the GDP bound to the G protein for a GTP.

Are the following organelles found in plant cells, animal cells, or both?
Nucleus
Cell membrane
Plasma membrane
Mitochondria
Vacuole
Endoplasmic reticulum
Cell wall
Chloroplasts
Ribosomes
Cytoplasm
Answer:
Explanation:
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information
The the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions.
The plasma membrane is the same as a cell membrane
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate
Vacuole. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.
The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.
