The RB protein in the tumor cells most likely d)binds to E2F, thereby promoting uncontrolled cell division. So, correct option is d.
The retinoblastoma protein (protein name truncated pRb; quality name contracted Rb, RB or RB1) is a proto-oncogenic cancer silencer protein that is broken in a few significant cancers. One capability of pRb is to forestall unnecessary cell development by hindering cell cycle movement until a phone is prepared to partition.
At the point when the cell is prepared to partition, pRb is phosphorylated, inactivating it, and the cell cycle is permitted to advance. It is likewise an enrollment specialist of a few chromatin renovating proteins, for example, methylases and acetylases.
pRb has a place with the pocket protein family, whose individuals have a pocket for the useful restricting of other proteins. Ought to an oncogenic protein, for example, those created by cells tainted by high-risk kinds of human papillomavirus, tie and inactivate pRb, this can prompt disease.
Hence, correct option is d.

Place the bones of the upper appendicular skeleton in order as they would be encountered in anatomical position as you moved distally.
Proximal phalanx Il Proximal
Humerus
Ulna
Middle phalanx II
Scapula
Clavicle
Distal phalanx II
Capitate
Metacarpal I
Lunate Distal
Answer:
Clavicle- Scapula- Humerus- Ulna- Lunate- Capitate- Metacarpal I- Proximal phalanx Il- Middle phalanx II- Distal phalanx II.
Explanation:
The upper appendicular skeleton starts with the clavicle, which is between the sternum and the scapula. Then we have the scapula, which is between the clavicle and the humerus. Following the humerus, we have the ulna and radius, which are in the forearm. Then we have the carpals bones, which are in two rows; the proximal row has the pisiform, the triquetrum, the lunate, the scaphoid; and the distal row has the capitate, the trapezium, the trapezoid, and the hamate. Then we the metacarpals, the proximal phalanges, the middle phalanxes, and the distal phalanxes.
When we have to place the bones from proximal to distal, like in this case, we have to locate the bones that are closer to the middle line of the body and then the ones that are far from it.

Now assume that while studying the species, another researcher suggests that changes in land-use in the habitat of axis deer in Texas may be creating food shortages for the species and that the habitat is only capable of supporting approximately 2500 animals. Does this change your analysis of the situation
Answer:
Yes.
Explanation:
Yes, this change of conditions also change the analysis of the situation because the analysis is related to the environmental conditions. When the environmental condition for an organisms changed so it also change its presence in that environment. If there is plenty of resources such as water, food and space for living, the population of that organism will be higher in that region while on the other hand, if this organisms is moved to a place where the resources such as water, food and space is scarce then it will leads to decrease in population of that organisms so we can say that change in conditions also bring change in our analysis.

Explanation:
g The primary digestive enzyme released by the stomach, as well as many of the digestive enzymes created and released by the pancreas, are initially released in their inactive form and must be activated after the fact. For one, explain how this activation occurs (and how it differs between the enzymes from these two organs), and for another, explain why this paradigm of releasing inactive enzymes is so important, physiologically.
Answer: The release of inactive form of enzyme is important because when the enzyme will active on its release it can digest the organs and glands from where it had been released to support the function of the enzyme only when it is required to be released and promote its functioning at the target site the enzyme is required to be released only in an inactive state.
Explanation:
Pepsin is a an enzyme secreted by the stomach cells in the inactive form that is called as pepsinogen. The function of the pepsinogen is to digest protein in the food. The activation of pepsin requires an acidic pH maintained by the hydrochloric acid in the gastric secretion of stomach. The pancreatic cells secrete enzyme trypsinogen which is activated into trypsin when it enters into the duodenum of the small intestine by the enzyme enteropeptidase.
elect all statements that accurately describe the structures or functions of mitochondria. Mitochondria are the sites of aerobic metabolism. Mitochondria have a permeable inner membrane and an impermeable outer membrane. Mitochondria regulate apoptosis. Mitochondrial DNA is packaged with histones. The configuration of mitochondria does not change. Mitochondria are included in the endomembrane system.
Answer:
The correct statements are -
Mitochondria are the sites of aerobic metabolism
Mitochondria regulate apoptosis.
Explanation:
Mitochondria is one of the eukaryotic cell organelles that are double membrane and plays important role in the different function of the cell. The main and major function of the mitochondria is aerobic metabolism that includes aerobic respiration where glucose converts into carbon dioxide and water with releases a high amount of energy in the form of ATP.
These also plays important role in programmed cell death or apoptosis it activates apoptosis by releasing protein by the inner and outer membrane. The inner membrane of mitochondria is impermeable and allows through transporters and outer membrane non-specifically permeable to low molecular substances. Mitochondrial DNA lacks histone protein and TFAM, an HMG-like protein involved in the process.
Streptococcus pneumoniae causes all of the following EXCEPT ________. Group of answer choices meningitis. lobar pneumonia. bronchopneumonia. necrotizing fasciitis. bacteremia.
Answer:
The correct answer is ''necrotizing fasciitis.''
Explanation:
Streptococcus pneumoniae belongs to the Streptococcaceae family. It is a Gram positive bacterium, normally facultative anaerobic, catalase negative, immobile, with an oval shape, surrounded by a capsule (does not present Lancefield antigens) and is usually grouped into chains of two (diplococcus) or more bacteria. It can give rise to a wide range of manifestations, among them, the most frequent but the least serious are upper respiratory tract infections, such as: otitis media, sinusitis, etc; while the less frequent but the most serious are: pneumococcal pneumonia, invasive pneumococcal disease, meningitis and septicemia. Necrotizing fasciitis is a rapidly progressive infection that affects the skin, subcutaneous cellular tissue, superficial and deep fascia, causing tissue necrosis and severe systemic toxicity, which, if not treated in a timely manner, is invariably fatal. The most common germs in immunocompetent people are Streptococcus pyogenes and Staphylococcus aureus. In patients with a defined gateway in the skin, the incidence of S. aureus is high. Deep necrotizing processes can be mono- or polymicrobial. In monomicrobial processes, pathogenesis is largely mediated by toxins (FN by S. pyogenes, FN by S. aureus, clostridial myonecrosis). In polymicrobial processes there is a synergism between aerobic and anaerobic germs. The most common aerobes are Enterobacteriaceae, Streptococcus group A, and S. aureus. The predominant anaerobes are Peptostreptococcus spp, Bacteroides fragilis group, Prevotella sp, Porphyromonas spp and Clostridium sp. Streptococcus pneumoniae belongs to the Streptococcaceae family.

Which of the following are functions of the reproductive organs in animals?
I. Produce sperm
II. Support the body
III. Protect the internal organs
IV. Make the eggs
I and II
II and IV
I and IV
II and III
Answer:
c
Explanation:
I and IV are the functions of the reproductive organs in animals.
What are Reproductive organs?
The female reproductive system serves a number of purposes. It aids in sexual reproduction in addition to enabling sexual activity.
The fertilized egg is then transferred to your uterus, where the lining has expanded due to the regular hormones produced during your menstrual cycle (also called your reproductive cycle).
The fertilized egg can implant into the thicker uterine lining once it's within your uterus and continue to grow there. Your menstrual period causes the uterine lining to shed if implantation doesn't occur. The female reproductive system also creates sex hormones that keep your menstrual cycle regular.
Therefore, I and IV are the functions of the reproductive organs in animals.

You are studying a plant whose seeds persist in the soil for a long time, normally only germinating when the seeds are brought to the surface in full sun by a disturbance such as a tree fall. However, in one of your experimental lineages you find that many seeds germinate when the surface is in full sun even if the seeds are buried too deep to grow to the surface before exhausting their reserves. You suspect that this lineage has a mutation that inhibits:
Answer:
The conversion of Pfr to Pr.
Explanation:
If the seeds germinates properly when the surface is in full sun and persist to germinate when buried deep into the soil, this shows that this lineage of seeds has a mutation that inhibits the conversion of Pfr to Pr
What would have a greater detrimental effect: the moon stops rotating or the Earth
stops rotating? Defend your answer.
Explanation:
when the moon stops rotating around the earth
earth will be crush down because it is the pull of the moon gravit on the earth that hold our planet earth in the place.
A greater detrimental effect would have been caused if the moon stops rotating or the Earth stops rotating. This is because the rotating celestial bodies exert some kind of gravitational pressure in order to make them in the exact locations.
What happens when the earth stops rotating?If the earth stops rotating, this inhibition of motion suddenly causes the momentum that would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
If the moon stops rotating or the earth stops rotating then the other celestial body disrupts down. Due to this, the pull of the moon's gravity on the earth or the pull of the earth's gravity on the sun holds each other in their exact location.
