bezimeni [28]2 years ago
3 0

Answer:

Lymph originates in blood capillaries that pick up tissue fluid. Mucous membranes prevent most pathogens from entering the body because of the stickiness of the mucus and the presence of lysozymes. Pus is made of dead neutrophils, macrophages, and other tissue debris from a damaged tissue.

D - Telophase
Eddi Din [679]

Answer:

A-B-C-D

Explanation:

PROPHASE; 1. chromosomes become thicker

2. nuclear membrane disintegrates

3. centrosome divide to form centrioles

4. centrioles move to the opposite polls of the cell

METAPHASE; 1. chromosomes get arranged at the equator

2. centrioles produce spindle fibre that attach to the middle of the chromosomes

ANAPHASE; 1. shortest stage of mitosis

2. spindles will pull apart each chromosomes to form chromatids

TELLOPHASE; 1.  each chromatid moves to opposite polls of the cell

2. nuclear membrane appears around both of them

3. the centrioles sill stop producing spindles

4. centrosomes will then form again

cytokinesis then divides by the cleavage furrow to form the two daughter cells

Why do embryologist study embryos?
ch4aika [34]
Embryologist study embryos because Embryology is central to evolutionary developmental biology ("evo-devo"), which studies the genetic control of the development process (e.g. morphogens), its link to cell signalling, its roles in certain diseases and mutations, and its links to stem cell research.

A phenotypic ratio for a dihybrid cross is predicted to be 9:3:3:1. The experimental values are:
Maslowich
Two traits that we are examining are the color (purple/white) and the smoothness. 
In our sample, we have 135 individuals ( 75 +28+24+8= 135).

Since we know that expected ratio of a dihybrid cross, is <span>9:3:3:1 we can calculate what is the expected values of each phenotype is.

So, for the white wrinkled phenotype, we expect that there will be one-sixteenth of the whole sample ( there are 16 parts of the whole sample 9+3+3+1=16).
So, we multiply the whole sample- 135 with one-sixteenth (or </span>0.0625) and get 8,4375.
When you calculate the values for all phenotypes you get results shown in the attached excel table.
When you have your expected and experimental values you compare them with a chi-square test. (The test determines if the difference between the expected and experimental results is statistically significant).
