Innate: keratinized epithelium

stratified squamous epithelium hypodermal areolar connective tissue antigen presenting cells major histocompatibility complexes complement (antibody -dependent pathway )

Innate or non-specific response is the first defense against invaders. Components of this response include physical (e.g. skin . mucosa) and chemical barriers against pathogens and cells such as Natural Killer cells, macrophages, neutrophils, dendritic cells, mast cells, basophils, eosinophils. Innate response reacts immediately.

Adaptive: immunoglobulin plasma cells agglutinin

helper t cells memory t cells cytotoxic t cells cd4+cells

t lymphocytes

Adaptive immune response or specific response is specific to the pathogen presented and mediated by lymphocytes, B and T cells. Adaptive immune response creates immunological memory after the first, initial l response to a specific pathogen which leads to enhanced response.

Determine the median value for foot width for males and for females. Describe in complete sentences the method you used to deter

Ipatiy [6.2K]

Answer:

This question is incomplete because of the absence of the data referred to in the question

Explanation:

This question is incomplete but the data referred to in the question is attached below

In order to determine the median value of any set of data, the data is first of all rearranged chronologically (ascending) and then the middle value is picked if the number of data is odd but if the number of data is even, the two middle values are added together and then divided by two to get the median.

From the data provided, the values (which are 10 in number) can be arranged as shown below (with the median values in bold)

Females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17

Males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13

Since the number of data is even, the two middle numbers (in bold) shall be added together and then divided to get the median as shown below

The median value for the females foot width is = 7.5 + 7.8/2 = 7.65 cm

The median value for the male foot width is = 9.2 + 9.3/2 = 9.25 cm

A botanist has discovered a new plant species and is trying to classify the plant. Its seed has one cotyledon, it has six flower

lana66690 [7]

The best suited group for the mentioned plant is Angiosperms and monocot.

Answer: Option C

<u>Explanation:</u>

As mentioned the seed of the plant has one cotyledon and the specific name for these type of plants whose seeds has one cotyledon is called Monocot, Suppose if the seed of the plant has two seeds, It is called dicot.

Hence we can conclude that the mentioned plant comes under monocot and not dicot. On the other hand, Angiosperms refers to the plants that has flowers with it and gymnosperms usually includes plants without flowers and hence we can classify the plant as Angiosperm and monocot.

In a two-point test cross, 36 of the offspring were recombinant types. The remaining 64 offspring were parental types. How many

Maksim231197 [3]

Answer:

Explanation:

A two-point test-cross is a cross between an individual with a double heterozygote genotype and a homo-zygous recessive individual in order to determine the recombination frequency between two linked genes. In genetics, one map unit (m.u.) can be defined as the measure of the distance (i.e., genetic distance instead of physical distance) between genes for which one (1) product of meiosis in one hundred (100) is recombinant. In this case, 36 of the offspring have the recombinant phenotype, while the remaining 64 offspring are not recombinant, and therefore both genes are separated by 36 mu (64 + 36 = 100 >> 36 mu).
