B) roan × roan
C) white × roan
D) red × roan
E) The answer cannot be determined from the information provided.
The cross between roan (heterozygous) cattle would produce offspring in the ratio of 1 red: 2 roan: 1 white. This is a scenario of a monohybrid cross, yielding a 1:2:1 ratio in offspring.
In this genetics problem, 'R' represents red coat color gene, 'r' represents white coat color gene, and the combination 'Rr' gives a roan coat color. To get a 1:2:1 ratio of red:roan:white, the cross must be between two heterozygotes, or roan-colored cattle (Rr × Rr). So, the correct option is B) roan × roan. This type of cross, known as a monohybrid cross, yields a genotypic and phenotypic ratio of 1:2:1 (1 RR: 2 Rr: 1 rr) in the offspring.

3. Where are you likely to find a photoautotroph?
in your refrigerator in the deepest parts of the ocean in your digestive system near the surfaces of lakes and streams
4. During what process do prokaryotes exchange genetic information? (1 point)
cell division binary fission conjugation endospore formation
5. What would be a direct consequence of the disappearance of nitrogen-fixing prokaryotes?
Dead organisms
2.Facultative anaerobes can survive either with oxygen or without it. This organism can live and grow in the absence of oxygen. The correct answer is:
Facultative anaerobes
3.Photoautotroph are organisms that carry out photosynthesis. The place where you are likely to find a photoautotroph is near the surface of lakes, streams, and oceans. The correct answer is:
Near the surfaces of lakes and streams
4.Prokaryotes are the smallest and most abundant organisms on the Earth. They range in size from 1 to 5 micrometers. This organisms are classified as Bacteria or Archaea. Most of them exchange genetic information by a process called conjugation. The correct answer is:
Conjugation
I hope it helps, Regards.

B. notochord
C. pharyngeal slits
D. dorsal fin.
2. Ancient chordates are thought to be most closely related to which of the following species?
A. spiders
B. earthworms
C. octopi
D. sea stars
The notochord is a flexible, supporting structure found only in chordates. Ancient chordates are most closely related to octopi.
The correct answer for the first question is B. notochord. The notochord is a flexible, supporting structure found only in chordates.
It provides support to the body and serves as a precursor to the vertebral column in vertebrates. Examples of chordates include fish, birds, and mammals.
The correct answer for the second question is C. octopi. Ancient chordates are thought to be most closely related to cephalopods like octopi.
Both groups share certain characteristics in their body structure and development.
