Explanation:

TLR also called toll-like receptors play crucial role in innate immune response. They are single spanning proteins and are present on dendritic cells and macrophages.

The pathogen when enters the body via skin or epithelial of mucosal membrane, they are recognized by TLR that further activates the immune response.

If you were to try and pair a thymine with a cytosine (a non Watson-Crick base pairing), then would you expect to see any stabil
Artyom0805 [142]

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.

What was a major problem for anthropologists when they were just studying objects in museum collections?
tia_tia [17]

A major problem for anthropologists when they were just studying objects in museum collections was that the objects were viewed as isolated from their cultural context.

<h3>What is Anthropology?</h3>

Anthropology is the scientific study of humans and includes the study of historical and contemporary human species as well as human behavior, biology, cultures, civilizations, and linguistics. While cultural anthropology examines cultural meaning, including norms and values, social anthropology explores patterns of behavior.

Today, the phrase sociocultural anthropology is frequently employed as a portmanteau. Language's impact on social life is the subject of linguistic anthropology. The biological evolution of people is studied in biological or physical anthropology.

Archaeological anthropology, sometimes known as "anthropology of the past," examines physical evidence to study human behavior. In North America and Asia, it is regarded as a subfield of anthropology, but in Europe it is viewed as a field unto itself or categorized under other related fields like paleontology and history.

A semi permeable bag (permeable to water but not to sucrose) contains a 2 % sucrose solution.
Burka [1]

Answer:

a) A beaker filled with 1 liter of deionized water?  - water will flow into the bag so its volume will increase. The solution is <u>hypotonic</u>

b) A beaker filled with 1 liter of 10% sucrose solution?  - water will flow out of the bag so its volume will reduce. The solution is <u>hypertonic</u>

c) A beaker filled with 1 liter of 2% sucrose solution - the volume of water in the bag will stay the same as the two solutions are in equilibrium. The solution is <u>isotonic</u>

Explanation:

Water moves by osmosis through a semi-permeable membrane. Osmosis describes the simple diffusion of water molecules.

Water molecules will move from a high concentration to a low concentration.

  • If the bag of 2% sucrose solution is placed in a beaker of deionized water, the concentration of water in the deionized water is in the beaker higher than in the bag (because the water in the bag contains 2% sucrose). Therefore, the water in the beaker will move from a high concentration outside the bag to a lower concentration inside the bag
  • If the bag of 2% sucrose solution is placed in a beaker of 10% sucrose solution, the concentration of water in the bag is higher than in the beaker (because there is more sucrose in the beaker). Therefore, the water in the bag will move from a higher concentration inside the bag to a lower concentration outside the bag.  
  • When the concentration of water is equal, the movment of water molecules reaches an equilibrium and there will be no change in the volume of water in the bag
