coefficient of relatedness (fraction of genes shared), B is benefit, the average number of extra
offspring that the recipient of an altruistic act produces, and C is cost, how many fewer offspring
the altruist produces. Let's say that members of species X produce 4 offspring on average.
Individual A of species X is in a perilous situation that will result in its death if the individual A
does not get help. First cousin of individual A decides to risk its own life in order to save
Individual A. what would be maximum risk of death for the cousin, in order for altruistic act to
be favored by natural selection?

Answer:
Hamilton's rule, mathematical formula that supports the notion that natural selection favors genetic success, not reproductive success per sea.

Humans, like other organisms, require energy for growth and repair. When cells create ATP for energy, carbon dioxide is produced as a waste product. How does the body respond to this process in order to maintain homeostasis?
Answer:
The circulatory and respiratory systems interact to transport carbon dioxide to the lungs, where it is expelled from the body.
Explanation:
Carbon dioxide produced by the cells and tissues during cellular respiration is removed from the body through the interaction of the circulatory and respiratory system. The medium of transport of carbon dioxide is the blood which carries to the lungs, where it is expelled from the body in ordernto maintain homeostasis in the body.
Carbon dioxide molecules are transported in the blood from body tissues to the lungs in three ways:
1. Dissolution directly into the blood - due to its greater solubility in blood than oxygen, carbon dioxide is dissolved in blood plasma. On reaching the lungs, it leaves the blood by diffusion and is then expelled out of the body.
2. Binding to hemoglobin - carbon dioxide binds reversibly with haemoglobin in the red blood cells to form a molecule called carbaminohemoglobin. When it reaches the lungs, the carbon dioxide freely dissociate from the hemoglobin and is expelled from the body.
3. Carried as a bicarbonate ion - the majority of carbon dioxide molecules are carried as part of the bicarbonate buffer system. In this system, carbon dioxide diffuses into the red blood cells. The enzyme carbonic anhydrase within the red blood cells quickly converts the carbon dioxide into carbonic acid (H2CO3) which then dissociates into bicarbonate and hydrogen ions. The bicarbonate ions leaves the red blood cells in exchange for chloride ions in the plasma. The bicarbonate ions then travel in plasma to the lungs, where they enter the red blood cells again. It combines with hydrogen ions from the haemoglobin to form carbonic acid. Carbonic anhydrase breaks carbonic acid down into water and carbon dioxide which is then expelled from the lungs.

Which of the following statements correctly summarizes the process of photosynthesis?
A. Reactions and the Calvin Benson cycle of the grana release oxygen into the atmosphere.
B. Light dependent reactions convert CO2 to carbohydrates, which light independent reactions use to produce NADPH2 and ATP.
C. CO2 is converted to carbohydrates through reactions fueled by products from the light independent reactions.
D. Reactions in the thylakoids capture free energy from sunlight and use it to convert glucose and oxygen to water and carbon dioxide.
The correct statement would be 'CO2 is converted to carbohydrates through reactions fueled by-products from the light DEPENDENT reactions'. Photosynthesis produces simple carbohydrates.
What is photosynthesis?Photosynthesis is a series of chemical reactions by which plants can produce simple carbohydrates by using the energy from the sun and carbon dioxide.
Photosynthesis has two types of reactions: light-dependent reactions and light-independent reactions.
Light-dependent reactions produce energy (mainly in the form of ATP), whereas light-independent reactions produce carbohydrates (i.e., glucose).

what happens to the original cell's chromosome during fission?
Answer:
It is a austic kid
Explanation:
Explanation:
Fission or binary fission is a process of cell division, used by single-celled organisms (also known as prokaryotes). This division is a form of asexual reproduction and results in a genetically identical offspring. Prokaryotes contain a single DNA molecule. During the fission process, replication of this DNA molecules occurs and the cell ends up with two copies of DNA molecule. These molecules are separated and are attached to different parts of cell membrane. This part of fission process is followed by actual cell division into two daughter cells. Each daughter cell ends up with one DNA molecule. Thus, each daughter cell is identical to the parent cell in all respects and the number of chromosomes are same in both the parent and daughter cells.
In comparison, eukaryotes undergo sexual reproduction.

How did Francesco Redi disprove the idea of spontaneous generation?
He showed that flies were not produced by meat.
He showed that microorganisms are present in air.
He showed that microorganisms cause disease.
He showed that flies spread disease.
Francesco Redi showed that microorganisms are present in air thereby disproving the idea of spontaneous generation and is denoted as option B.
What is Spontaneous generation?This is supposed production of living organisms from non living substances.
The jar was left open and had maggots in it means the flies laid their eggs which later turned to the maggot which was what Redi observed during the experiment.

D) contains less water vapor than the air you breathe in.
Answer:
A) contains more carbon dioxide than the air you breathe in
Explanation:
So based on our basic knowledge, we know that we breathe in air, keep the oxygen, and breathe out everything else plus the carbon dioxide we make in our lungs. So A is really the only one that makes sense.

What is the difference between a guard cell and a white blood cell?
Guard cells are found in plants and white blood cells are found in animals.
What are guard cells?Guard cells are specialised plant cells that regulate gas exchange in the epidermis of leaves, stems, and other organs. They are created in pairs, with a stomatal orifice separating them. What are white blood cells?The immune system's white blood cells, also known as leukocytes or leucocytes, are responsible for defending the body against both infectious diseases and foreign invaders. All white blood cells are created and developed from hematopoietic stem cells, which are multipotent cells found in the bone marrow. All parts of the body, including the blood and lymphatic system, include leukocytes.Guard cells function to allow gaseous exchange and white blood cells are responsible for the functioning of the immune system.

Answer: Plants that always produce the same traits as their parents when they are self pollinated
Mendel used self-pollination in pea plants to grow true-breeding plants for his experiments. When a true-breeding plant self-pollinates, its offspring all have the same traits as the parent. For example, a true-breeding plant with purple flowers always has offspring with purple flowers.

Read the following summary, which describes blood flow and heart output in space. Then, answer the question.
The heart doesn't have to do as much work to pump blood when in orbit. After only one day beyond Earth's gravity, astronauts have a lower blood volume. They can lose as much as 20 percent of their blood volume while on a space mission. Since the body has less blood to push around and the heart is pushing more blood with each beat, an astronaut's heart rate also slows down to compensate.

Respiratory is the number of respiratory movements per minute. Place one hand on your chest and estimate the respiratory at rest.
PLS HELP!
Answer:
The correct answer is - 20.
Explanation:
Respiratory rate is the number of total breaths that occur in a minute. The breathing includes respiratory movements of expansion and contraction of the thoracic cavity or chest cavity.
The calculation of the respiratory at rest can be performed by counting the total number of rising or falling of the chest in a minute. The normal range of respiratory of a healthy adult is between 16 to 20 per minute however it depends on factors like age, medical conditions. Above 25 breaths per minute is considered as elevated respiratory.
