Answer:
The cell is flexible and assumes a bell shape as it passes through extremely small blood vessels. It is covered with a membrane composed of lipids and proteins, lacks a nucleus, and contains hemoglobin—a red iron-rich protein that binds oxygen.
Answer:
The cell is flexible and takes the form of a bell through extremely small blood vessels. It is clothed in a fluid and protein-membrane, lacks a nucleus, and has hemoglobin—a rich red iron protein that binds oxygen.
Explanation:
The hemoglobin in red blood cells contains four iron-binding heme groups.
Heme groups of hemoglobin are binding on oxygen. Each molecule of hemoglobin can bind up to four molecules of oxygen.
Hemoglobin has a cooperative binding affinity to oxygen. The saturation of the molecule increases by oxygen. The connection of the initial molecule of oxygen affects the form of the other binding sites. For additional oxygen molecules, the binding becomes more favorable.
The four iron-binding hemo-groups are located in each hemoglobin molecule. Hemoglobin is known as oxygen-bound hemoglobin.
The reversible carbon dioxide is transformed into the carbonic acid reaction by the enzyme carbenoid anhydrase by the Red blood cells altering the blood PH.
Instead of being converted to carbonic acid, pH is controlled by carbon dioxide bindings to hemoglobin.
CO2: The enzyme found in RBCs catalyzing the reaction between carbonic anhydrase and carbonate dioxide and water.
Co-operative binding: When a first molecule is binding to a binding location, the same molecule is favored for the remainder of the binding locations by means of increased binding affinity.

A. global warming, B. greenhouse effect, C. botanical gardens effect
Explain why.
Answer:
b.greenhouse effect
Explanation:
Trap heat similar to the glass roof of a greenhouse.These heat-trapping gases are called greenhouse gases
Answer:
B. Greenhouse effect
Explanation:
What is the greenhouse effect?

The greenhouse effect is the way in which heat is trapped close to Earth's surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them.
To determine the density of a rabbit population, one would need to know the number of rabbits and __________. View Available Hint(s) To determine the density of a rabbit population, one would need to know the number of rabbits and __________. their pattern of dispersion the size of the region in which they live the factors that limit population growth for that rabbit population the growth rate of the population the birth rate
Answer:
The growth rate.
Explanation:
To determine the density of a rabbit population, one would need to know the number of rabbits and the growth rate of rabbit's population because both factors allow us to determined the population of rabbit in a specific region. If we know the existing population of rabbits in a particular area as well as the growth rate at which the rabbit population increases so we can find out the density of rabbit population in a specific time period.
Consider this plant cell. The organelles in a plant cell are labeled. Part G is the middle layer of the cell. Which organelle is labeled G?
Answer:
Hi. You didn't show the picture that shows organelle G, but since you showed that organelle is the middle layer of the cell, we can say that it is the plasma membrane.
Explanation:
In general, we can state that the plant cell has three layers, the cell wall, the plasma membrane and the cytoplasm. The cytoplasm is the inner layer, where most of the organelles and the cell nucleus are located. Above the cytoplasm is the plasma membrane, which is semi-permeable and promotes the regulation of the entry and exit of substances from within the cell. Above this membrane is the cell wall, which is an impermeable structure that protects the cell and promotes its rigidity. In this case, we can consider that the middle layer of the cell is the plasma membrane.

"I don't get it. Why do I need to learn about meiosis to understand about variation in a species?" moaned Trina. How would you explain to her what the relationship is between the two?
Answer:
The cell division that halved the no. of chromosomes is the meiosis. The meiosis takes place during formation of gametes (eggs & sperms) in higher organisms. eggs & sperms posses only one chromosomes of each pair of chromosomal set. (2n➡️n).
When these gametes fuse to form the zygite, the chromosomes become n+n➡️2n again.

Identifying an individual's genetically influenced health risks could increase their potential to achieve optimal health.
Answer:
Yes.
Explanation:
Yes, Identifying an individual's genetically influenced health risks could increase their potential to achieve optimal health because necessary steps can be taken in order to prevent the disease from more spreading and cause damaged to the body. Identification of genetical disease can be prevented to cause damage if the factors that triggers the disease can be avoided so we can conclude that identification of genetically influenced health risks can increase the chances of getting good health.

Three reasons that might have influenced authorities in the department of agriculture to use a higher percentage of Nguni on the communal and emerging sector of livestock farmers in South Africa in 2003
Answer:
Tolerance to heat, light and parasite.
Explanation:
Characteristics of tolerance to heat, light and parasite are the three reasons that might use a higher percentage of Nguni on the sector of livestock farmers in South Africa in 2003. The temperature of South Africa is extremely high which can be tolerated by the Nguni cattle due to its good characteristics. The Nguni cattle can bear extreme temperature, high intensity of light and resistance to parasites make it best suited for that environment.

Reproduction for dolphins and badgers and people is more complicated because
A. we have to apply for a license before we can reproduce
B. have to find a partner
C. go through the cellular process of MITOSIS to produce sex cells.
Answer:
B. have to find a partner
Explanation:
When two badgers get together and fall in love, a sperm cell from the father which contains a copy of half of his DNA, only half, combines with the egg cell of the mother, which contains half a copy of her DNA. The result is a brand new cell with all the information to divide and grow up into a brand new badger. The new child matures to be similar to our parents, but also unique, because she developed some traits from her mother’s DNA, and some from her father. Her new combination of traits can be passed on to her children, and again.

OD. The species adapted to each island's unique habitat.
The statement that explains each island in the Galapagos has unique kinds of iguanas is that the species adapted to each island's unique habitat. The correct option is D.
What is adaptation?Adaptation is defined in biology as a heritable behavioral, morphological, or physiological trait that has evolved through natural selection and maintains or increases an organism's fitness under a given set of environmental conditions.
To survive, all organisms must adapt to their surroundings. This entails adapting to the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space.
The marine iguana is the only lizard in the world that can live and forage at sea, and it is only found in the Galapagos Islands.
There are eleven very similar subspecies found on various islands, with Isabela and Fernandina having the most. The species adapted to the distinct habitats of each island.
Thus, the correct option is D.
