George Beadle concluded that teosinte is the likely ancestor of maize (corn), even though the two plants appear very different.

Answer:

Option B

Explanation:

ALL options are as follows -

a. teosinte and maize can produce fertile hybrids.

b. teosinte and maize have similar chromosomes.

c. Both Teosinte and maize have naked, soft kernel.

d. Teosinte and maize can produce fertile hybrids

Solution

Beadle started working on maize genetics since 1962 after joining graduate school at Cornell University.  

During his research he found that the chromosomes of teosinte and maize possess higher similarity and also show signs of intercross ability of the two species and hence confirmed that wild teosinte is an ancestor of domesticated maize.  

He later concluded that there are only 4 to 5 genes that make these two species different from each other rest all is similar.  

Option B is correct

the size difference between most multicellular hosts and their pathogens results in which of the following evolutionary advantag
professor190 [17]

Pathogens can adapt more quickly than hosts since they have higher populations and faster generation periods.

Pathogens, of course, have the advantage in this evolutionary game because they can change far more quickly than the hosts—especially in long-lived animals like humans—due to their high population numbers and rapid generation rates. The relationship between surface area and complement activation shows how bacterial pathogenicity may be influenced by tiny size. The region of the microbial surface may also have a role in their action since other antimicrobial agents are focused there. A pathogen reacts with the host and creates infection, which results in the host being ill. Any dangerous microbial agent, including bacteria, viruses, protozoa, fungi, and helminths, might be considered a pathogen.

⭐️HELP PLEASE<br><br> Why did prokaryotic cells come before eukaryotic cells?
stiks02 [169]

Answer:

The complex eukaryotic cell ushered in a whole new era for life on Earth, because these cells evolved into multicellular organisms. Evidence supports the idea that eukaryotic cells are actually the descendents of separate prokaryotic cells that joined together in a symbiotic union.
