How are dinosaurs are like ( Related) crocs
How are dinosaurs like( related) chickens
Answer (How dinosaurs are related to crocodiles):
Along with pterosaurs and dinosaurs, crocodiles were an offshoot of the archosaurs, the "ruling lizards" of the early to middle Triassic period; needless to say, the earliest dinosaurs and the earliest crocodiles resembled one another a lot more than either resembled the first pterosaurs, which also evolved from archosaurs. What distinguished the first crocodiles from the first dinosaurs was the shape and musculature of their jaws, which tended to be much more deadly, as well as their relatively splayed limbs—as opposed to the straight, "locked-in" legs of theropod dinosaurs. It was only well into the Mesozoic Era that crocodiles evolved the three main traits with which they're associated today: stubby legs, sleek, armored bodies, and marine lifestyles.
Answer (how dinosaurs are related to chickens):
The scientific evidence comes from a study in which the amino-acid sequence from T. Rex collagen was compared to that of various modern species. It proved to be more similar to the chicken than any other creature alive today.
So, are chickens dinosaurs? No – the birds are a distinct group of animals, but they descend from the dinosaurs, and it’s not too much of a twist of facts to call them modern dinosaurs.
There are many similarities between the two types of animal, largely to do with bone structure. It also appears that many of the dinosaurs had feathers – not for flight, but as adapted scales, to assist in heat regulation, and/or to assist in courtship displays, as in modern birds.

Empties bile into the duodenum from the gallbladder.
Bile empties from the gallbladder into the bile duct. The bile duct merge with the pancreatic duct to form the ampulla of Vater, which empties into the duodenum.
What releases bile into the duodenum?The gallbladder
The bile made by the liver is kept in the gallbladder. This is a pear-shaped organ found below the liver. Then, when food is eaten, the gallbladder compressed and releases stored bile into the duodenum to help break down the fats.
Thus, Bile empties from the gallbladder into the common bile duct.

During the cell cycle, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. at the end of this cycle, the cyclins degrade to prevent further signaling for the cell to divide.
uncontrolled production of cyclins will most likely result in —
f) the formation of tumors
g) the immediate death of the cell
h) the transfer of cyclins to other cells
j) the formation of haploid cells
Uncontrolled production of cyclin proteins will most likely result in the formation of tumors (Option f).
What are cyclins?Cyclins are proteins that control the progression through the cell cycle by their interaction with specific kinases.
These cyclins-dependent kinases (cdks) can be phosphorylated as a control points during the cell cycle.
Uncontrolled production of cyclins will produce uncontrolled cells that divide forming tumors.

how many cells are in this picture? and which phase are most of the cells in-interphase, mitosis or cytokinesis
Answer:
~100 cells,
Explanation:
I counted around 102 cells in the picture. For your seond question I am a bit confused.
You asked what phase are they in and gave interphase, mitosis and cytokineses as the options. While interphase and cytokinesis are phases of mitosis. Therefore in theory all the cells are going through mitosis.
Since most of the cells are looking like dense balls, we can say they are going through interphase.
P.S. I also see some going through anaphase, metaphase and cytokinesis, but they are seldom in numbers compared to interphase cells.

There is a maximum between the two input values -2 and 2.
A quadratic function is the function which has 2 as its highest power. Its genralised form is given as y=ax²+bx+c.
From the given table it can be observed that at extreme values of x, therefore, when x=-5 and x=9, the value of y is negative. Therefore, at any value above 9 and below -5, the value of the function will be always negative.
Further, it can be observed that the highest value of y is 9 which when the value of x is -1.
The only choice from the given option that includes -1 in its answer is -2 and 2.
To verify this a graph can be plotted for the function as shown below.
Hence, the maximum will be between -2 and 2.
