Answer:
Rr and rr
Explanation:
The genotypes of the parents would be heterozygous red (Rr) and true-breeding white (rr).
Since the allele for the red flower color (R) is dominant over that of the white flower color (r), for a cross to produce both red and white flower color plants, the red parent must be heterozygous (Rr) and the white parent true-breeding (rr).
Rr x rr
Rr Rr rr rr
Rr = red
rr = white
If the red parents is true-breeding
RR x rr
Rr Rr Rr Rr
All their offspring would be red without any white flower color.
Hence, the genotypes of the parent are Rr and rr.
Why is sickle cell anemia so harmful to its carriers?
Answer: BECAUSE IT MAKES THE RED BLOOD CELLS SHRINK
Explanation:
Answer:
Sickle cell anemia is harmful to the body because it is enagering your spleen and with less healthy red blood cells circulating in the body, you can become chronically anemic.
Sickle cell anemia puts your body at more risk for infection.

In all living things, the presence of what structure supports the cell theory.
cell membrane
chloroplast
cell wall
vacuole
Answer:
chloroplast
Explanation:
The spinal cord relays messages between the body and the brain. These messages control body functions like movement, bladder and bowel control and breathing. Each vertebra has a pair of spinal nerves that receive messages from the body (sensory impulses) and send messages to the body (motor impulses). The spinal nerves are numbered 1 to 55 from the neck down. The first eight as seen here are the vertebrate and send messages to the back of the head, neck, shoulders, arms, hands and diaphragm. A) cervical B) lumbar C) sacral D) thoracic

What is a niche, and how does it relate to evolution?
Answer:
The evolution of species’ niches is a process that is fundamental to investigations in numerous fields of biology, including speciation, community assembly, and long-term regional and global diversification processes. It forms the nexus between ecological and evolutionary questions. Topics as diverse as ecological speciation, niche conservatism, species coexistence, and historical biogeography all rely on interpreting patterns and drivers of species’ niches through time and across landscapes. Despite this importance, a distinct research agenda concerning niche evolution as a discrete topic of inquiry has yet to emerge. Niche evolution is often considered as a sidebar or of secondary importance when addressing questions such as “how did two species diverge?” Basic questions such as “what is a niche,” “what is the biological basis of niche evolution,” “at what scale should we evaluate niche evolution,” and “how can we observe niche evolution at different timescales” have rarely been addressed directly, or not at all in some systems. However, various intellectual threads connecting these ideas are evident in a number of recent and historical publications, giving some semblance of form to a framework for interpreting and evaluating niche evolution, and outlining major areas for future research from an evolutionary perspective. There is a reverse perspective from the macroecological scale as well, with questions involving coexistence, distributions and ranges, food webs, and other organismal attributes

What is the function of cholesterol?
to keep the cell membrane from falling apart
to line the arteries of organisms
to store energy
to give us quick energy
Answer:
to store energy
Explanation:
Its main function is to maintain the integrity and fluidity of cell membranes and to serve as a precursor for the synthesis of substances that are vital for the organism including steroid hormones, bile acids, and vitamin D. Cholesterol is essential for making a number of critical hormones, including the stress hormone cortisol. Cholesterol is also used to make the sex hormones testosterone, progesterone, and estrogen. 2 The liver also uses cholesterol to make bile, a fluid that plays a vital role in the processing and digestion of fats.

what are the two main organs involved in the respiratory system?
Answer: The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system.
Explanation: Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood. Common problems include allergies, diseases or infections.
What is the respiratory system?
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
