In the photo the question is not there
The answer is letter A. The entire population of the species
spends winter in Oyamel
Oyamel is one of the most popular places where Monarch
butterflies would breed over winter season. But because of deforestation and
climate change there was a big decline on the number of monarch butterflies
going to Mexico and back over the past few years.
Note about the question:
You will find the pedigree in the attached file
Answer:
The boy and the girl represented by solid black-colored square and circle, respectively, are affected with sickle cell anemia
Explanation: A pedigree tells information about the phenotype of individuals in the family. There are certain symbols to take into count when analyzing a pedigree. Among many others, a few to consider in this particular problem are
- Squares that represent males
- Circles that represent females
- White shapes that represent healthy or normal individuals
- Black shapes that represent affected individuals
The affection in this problem comes from the paternal line. Susan´s husband is affected by sickle cell anemia. His mother and his grandmother are also affected.
Susan is a healthy woman. They had four children. Two girls (circles) and two boys (squares).
From this last generation, one of the girls (black circle) and one of the boys (black square) are affected.
Answer:
Option B is the answer, that is, proximity to major businesses who use flower shops.
Answer:
A) Dendritic cells and macrophages, although they are also found in other cells that belong, or not, to the immune system.
B) The innate immune response
Explanation:
The immune system is equipped with specialized receptors for the detection of pathogens such as bacteria or viruses, which are called receptors that recognize patterns (PRRs). These proteins are a key element in the innate system and are expressed primarily in antigen presenting cells, such as <u>dendritic cells and macrophages, although they are also found in other cells that belong, or not, to the immune system.</u>
<u>
The innate immune response</u> begins with the recognition of highly conserved molecular structures and present in large groups of microorganisms called 'molecular patterns associated with pathogens' (PAMP). This recognition is done by the 'pattern recognition receptors' (RRP) of the host.
The best known bacterial PAMPs are:
Lipopolysaccharides (LPS)
Peptidoglucan
Lipoteic Acids
Mananas (Mannose
)
Bacterial DNA
Double stranded RNA
Glucans
These PAMP are essential for the survival and pathogenicity of bacteria.
