Answer:
It happens in the diastolic phase of the cardiac cycle
Explanation:
During the diastolic phase of the cardiac cycle, blood is allowed to enter the heart when it relaxes after a contraction.
Approximately one systole (contraction phase) that lasts 300 milliseconds and a diastole of 500 milliseconds.
Avoidant attachment types of babies are most likely to be outwardly unaffected by a caregiver leaving or returning.
<h3>
Avoidant attachment</h3>
The way you typically behave or think when interacting with others is known as your avoidant attachment style. Your attachment type is influenced by the early interactions you have with your parents or other primary caregivers. Your attachment style may be secure, anxious, avoidant, disorganized, or another type depending on how attentive and connected these caregivers were to you. In trying to keep the peace and their caregiver near by, the youngster ignores their own challenges and wants. They still experience difficulties and negative emotions like anxiety or depression, but they do it on their own and downplay their significance. Through maturity, a person's attachment style frequently persists, which may have an effect on their friendships, romantic connections, and other connections. The avoidant attachment patterns present in today's population are about 30%.

Answer:
Yes, two hydrogen bonds could form between thymine and cytosine.
Explanation:
Cytosine is a pyrimidine base found in both DNA and RNA, and Thymine is a pyrimidine base found in only DNA. Electronegative Oxygen and Nitrogen atoms with free lone pairs are potential hydrogen bond acceptors. Hydrogen atoms attached to very electronegative atoms like Oxygen and Nitrogen have strong partial positive charge and are potential hydrogen bond donors.
One hydrogen bond could form between the C4 carbonyl group on thymine which is a hydrogen bond acceptor and the C4 amino group on cytosine which is a hydrogen bond donor. Also, another hydrogen bond could be formed between N3 of thymine which is a hydrogen bond donor and the N3 of cytosine that is a hydrogen bond acceptor.
It is important to note that hydrogen bond cannot be formed between them because the C2 carbonyl groups found on both bases are both hydrogen bond acceptors.
