Explanation:
In a haplodiploid mating system, how can the coefficient of relatedness between two sisters be 0.75 (75%)? Females are haploid, and they pass on 100% of their genes, whereas males are diploid and pass on 50% of their genes, meaning that the coefficient of relatedness is 0.75. Females can reproduce asexually, meaning they produce clones, and those clones share on average 75% of the genes of their sisters. If a queen mates with a single drone, then all the resulting females have all of the same genetic contribution from the male, since males are haploid and contribute 100% of their genes. Male and female bees are both diploid. The males contribute 100% of their genes to their offspring, and females contribute 50%. Therefore, each female offspring shares 75% of her genes with her sister siblings on average.
Answer:
If a queen mates with a single drone, then all the resulting females have all of the same genetic contribution from the male, since males are haploid and contribute 100% of their genes
Explanation:
Haplodiploidy is a type of sex-determination system where males are haploid (i.e., they contain only a set of chromosomes 'n') and develop from unfertilized eggs, whereas females are diploid (i.e., they contain two complete sets of chromosomes '2n') and develop from fertilized eggs. The bees show this haplodiploid system of sex determination, which is quite common to many hymenopterans. In bees, workers and queens are diploid (2n) females and contain 32 chromosomes, a set of 16 chromosomes is contributed by the queen's egg, and another set of 16 chromosomes is contributed by the drone sperm (16 + 16 = 32 chromosomes). On the other hand, drones are haploid (n) males and contain only one set of 16 chromosomes, which is exclusively contributed by the queen's egg.
with reference to enzymes, what does "denatured" mean?
Answer:
Enzymes work consistently until they are dissolved, or become denatured. When enzymes denature, they are no longer active and cannot function. Extreme temperature and the wrong levels of pH -- a measure of a substance's acidity or alkalinity -- can cause enzymes to become denatured.

For summer squash, the dominant allele Y for gene 1 leads to yellow color while the recessive allele y leads to green color. Alleles of gene 2 can prevent color formation, with the dominant allele W leading to white squash while the recessive allele w does not interfere with color development. How many phenotypes would be observed among the offspring of the following cross: YyWw x YyWw
Answer:

what is the meaning of respiration
Answer:
in physiology respiration is the movement of oxygen from the outside environment to the cells with tissues and the removal of carbon dioxide in the opposite direction .. in contrast exhalation is usually a passive process
hope it's helpful
Answer:
The process of breathing.
Explanation:
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
**Physiological respiration and cellular respiration are not the same. People sometimes use the word "respiration" to refer to the process of cellular respiration, which is a cellular process in which carbohydrates are converted into energy. The two are related processes, but they are not the same.

Ecotourism can provide an incentive for local people to preserve the environment in order to attract more visitors, but sometimes development is done with little planning for long-term environmental impacts. On a small island in the Caribbean, a local group is considering opening a resort for ecotourism. If they wish to build a sustainable and ecofriendly business, what should be the next steps in their plan?
A. Investigate the ecological impacts and gather evidence on which to base their decisions
B. Hire an agent to locate a suitable property and start developing infrastructure
C. Market the development to investors and explain ecotourism to them to raise money for the resort
D. Determine what types of activities the resort will offer and hire staff
Answer: The next steps in their plan should be to (Investigate the ecological impacts and gather evidence on which to base their decisions). The correct option is A.
Explanation:
ECOTOURISM is defined as the visitation of individuals (tourist) to natural areas that conserve the environment and sustains the well-being of the local people. It has to do with the interaction of the biotic components of the natural environment by tourists. This has the advantage of providing an incentive for the local inhabitants but can cause a long term negative environmental impact of not properly planned.
Conservation of these natural resources improves the quality of lives. It enables the inhabitants to live in a clean and healthy environment (eco-friendly). To set up a tourism center, certain rules and regulations needs to be met in order to avoid endangering both the biotic and abiotic components of the ecosystem. Therefore these local groups should investigate the ecological impacts and gather evidence on which to base their decisions. This would help conclude if a particular selected environment is conducive.

At a chemical synapse, the intensity of the stimulus is coded by _______. At a chemical synapse, the intensity of the stimulus is coded by _______. the amount of calcium that enters the axon terminal the amount of neurotransmitter released and the amount of calcium that enters the axon terminal the amount of neurotransmitter released the size of the action potential the size of the action potential and the amount of neurotransmitter released
Answer:
The correct answer is - the amount of neurotransmitter released and the amount of calcium that enters the axon terminal.
Explanation:
The intensity of the signals or stimulus depends on the amount of the neurotransmitter such as acetylcholine, dopamine and the amount of calcium that enters the axon terminal.
A neurotransmitter is a chemical that carries, boost or balance a signal and send stimulus or signals throughout the body. When an action potential reaches the nerve terminal calcium channels open and enters.

Answer:
robert hooke
Explanation:
The weight of body is 420 N . Calculate it's mass..
Here,
Force = 420N
Gravity = 9.8m/s^2
Mass = ?
Now,
Force = Mass * Gravity
420 = Mass * 9.8
420/9.8 = Mass
Mass = 42.85Kg

Explanation:
Flat discs inside chloroplasts that are arranged in stacks are called (2) ______________________ (3) ______________________ are light-absorbing substances that are inside chloroplasts. They absorb light of different (4) ______________________. The green pigment in plants that is essential for photosynthesis is (5) ______________________. Light energy absorbed by this pigment excites (6) ______________________. They are transferred to a(n) (7) ______________________ ______________________. Then they move down an electron transport chain.
Answer:
Flat discs inside chloroplasts that are arranged in stacks are called (2) __thylakoids_. (3) __Pigments__ are light-absorbing substances that are inside chloroplasts. They absorb light of different (4) __wavelenghs__. The green pigment in plants that is essential for photosynthesis is (5) __Chlorophyll __. Light energy absorbed by this pigment excites (6) ____electrons___. They are transferred to a(n) (7) _Electron Carrier_. Then they move down an electron transport chain.
Explanation:
The chloroplasts are limited by an outer membrane and an inner one. In the middle of the two membranes, there is a space left called intermembrane space. In the interior of the inner membrane, there is another space known as the stroma. Within the stroma, there is the third system of membranes, known as thylakoids. They are disk-shaped structures, limited by a membrane, and in their interior, there is a space named thylakoid space.
Thylakoids are arranged as piles, receiving the name of grana. Grana connect to each other by a longer thylakoid membrane. The photosynthetic pigments are placed in the thylakoids, where it occurs light-dependent reactions. These molecules are in charge of light absorption. The most common pigment is chlorophyll, which provides the typical green color of plants. When sunlight reaches the pigments, electrons get excited and move along the electron transport chain, places in the thylakoid membrane. This process occurs during photosynthesis, while new electrons provided by water molecules replace the excited ones. The final products are oxygen, ATP, and NADPH.
In the stroma, it takes a place the Calvin cycle.
