Answer:

tumor suppressor gene

Explanation:

A tumor suppressor gene is capable of modulating cellular processes during cell division and/or replication, thereby avoiding uncontrolled cell proliferation and tumor development. For example, the p53 gene is a tumor suppressor gene that encodes a protein (p53) which is well known to regulate critical cellular processes such as, for example, cell cycle arrest and programmed cell death (apoptosis). Moreover, breast cancer genes BRCA1 and BRCA2 are tumor suppressor genes that regulate the repair of damaged DNA through the Homologous recombination (HR) pathway. In consequence, mutations in BRCA1 and BRCA2 genes can increase the risk of developing breast cancer.

1. how does the mass amount affect acceleration?
Luden [163]

Answer:Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased. 2. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.Now we see that larger net forces create larger accelerations and larger masses reduce the size of the acceleration. In fact, an object's mass is a direct measure of an objects resistance to changing its motion, or its inertia .

Which of the following would be a virulence factor of a pathogen?
olga_2 [115]

Answer:

The correct answer is option - a surface protein allowing the pathogen to bind to host cells

Explanation:

Virulence factors are substances or molecules released by pathogens such as bacteria, fungi, viruses and protozoa that enhance their function effectiveness and enable them to get the following-

Attachment to host cell and surface.

Evasion of the immune response of the host.

Suppression or inhibition of the immune response  of host.

Getting nutrition from the host cells

Thus, the correct answer is option - a surface protein allowing the pathogen to bind to host cells.
