Identify at least 100 living organisms including animals and plants from your surroundings

What if humans cells were covered with exine.
The most resistant organic cellular layer

A gene of curly hair structure dominates over a gene of straight hair structure and hemophilia is X-linked recessive disease in a human. A healthy woman with curly hair got married to a healthy man with straight hair. They had two children: a hemophilic son with curly hair and a healthy daughter with straight hair. Determine the genotypes of the parents and their children. Determine the probability of birth of a healthy son with straight hair structure

A brown-eyed girl with normal sight got married to a blue-eyed man with normal sight. The father of the girl was blue-eyed and color-blind. What is F1? It is known that gene of brown color of eye dominates over the gene of blue eye color. The gene of color blindness is recessive and X-linked.

The gene of daltonism is recessive X-linked. Woman with normal sight, whose father had daltonism, got married to sick man. Determine the phenotypes and genotypes of children in this family, and the probability of birth of healthy children.

Peas can be either green (y) or yellow (Y) and round (R) or wrinkled (r) , if two parents are heterozygous for both traits , what are the phenotypes of the parents? (what will they look like?)

Can you please make a concept map with the main Idea as History of life. The words that are used are prokaryotes;eukaryotes;Fossils;Miller-Urey experiment; Redi: Pasteur; Needham; spontaneous generation; Biognesis; Paleozoic era; Mesozoic era; cenozoic era; Endosymbiosis; endosymbiotic theory; Cyanobacteria. After that is done can you make a connection key that show the connection for the relationship. Oh and sorry but can you label the lines as (A,B,C, and so on)
So it will start from A and show the connection to B. Thank you that is all if it can be done by today that would be great.

1. You have a double stranded (ds) DNA molecule. You want to use PCR to make multiple copies of a section of it. Suppose you start with one molecule of ds DNA and do 5 cycles of PCR.
A-1. How many different primers will you need? (1) (2) (3) (4) (5) (>5).
A-2. How many molecules of each primer will you need? (1) (2) (3) (4) (5) (>5).
A-3. Your primers are most likely to be (ss RNA) (ssDNA) (dsRNA) (dsRNA) (ss, but equally likely to be RNA or DNA). No explanation required for A-1 to A-3. Note: ds = double stranded; ss = single stranded.
A-4. Consider two different primers. (There may or may not be more, but stick to 2.) The two primers are probably (complementary) (unrelated in sequence) (the same sequence but one is ‘backwards’).

Many grocery stores spray their produce with fresh (0% salt) to make them more firm and plump. Is this water a hypertonic, hypotonic, or isotonic solution for the plants? What is different about plant cells that prevents them from bursting when exposed to this solution?
