The expected outcome for growth signal activating Ras is cell growth first, then DNA replication, then cell cycle arrest (Option 4).
<h3>What is the growth signal activating Ras?</h3>
The growth signal activating Ras is a signaling pathway associated with cell differentiation.
The growth signal activating Ras promotes the cell cycle through different types of growth factors.
In conclusion, signal activating Ras activates cell growth first, then DNA replication, then cell cycle arrest (Option 4).

The main aspect used to differ coniferous tree are their leaves. Coniferous leaves look like elongated needles, instead of the regular flatend out leaves we're used to
Further characteristics:
Seeds are hard and grow in large groups, stuck to eachother.
Coniferous are evergreen trees (don't shed leaves nor change the colour of these, although this rule does not apply to all of them).
They have spread worldwide.
Can withstand low temperaurees and can be found even in places like the Artic circle.
I've pasted some images down below that might help you a lot. (Left - leaves; Right - coniferous trees).
Hope it helped,
Happy homework/ study/ exam!
Answer: The trait is recessive because individual 17 has the trait but his parents do not
Explanation: if the trait was dominant one of his parents would have to have had it.
The best answer is A. Enzymes work best at a certain temperature, so that if the enzyme is outside it’s ideal temperature, it won’t function normally.
B and C are incorrect because enzymes are made of amino acids, not nucleus acids or simple sugars.
Because the scientists extracted the enzyme from the organism, the amino acid sequence cannot be different between the enzyme and the enzyme in the blood. Thus, D is incorrect.
