Does natural selection operate more efficiently on dominant or recessive alleles
Answer:
Selection against dominant alleles is more efficient than selection against recessive alleles.
Explanation:
Natural selection operates more efficiently on dominant alleles as compared to recessive alleles.
What do you mean by Natural Selection?Natural selection may be defined as the process through which populations of living organisms adapt and change.
Dominant alleles are expressed in the phenotypes of an organism, while the effect of the recessive alleles is masked or sheltered in the heterozygous condition.
Therefore, Natural selection operates more efficiently on dominant alleles as compared to recessive alleles.

During _____, the homologous chromosome pairs independently align themselves at the equator of the cell.
Answer:
Prophase I
Explanation:
During prophase I, homologous chromosomes pair up and exchange sections of DNA.
During prophase I, the homologous chromosome pairs independently align themselves at the equator of the cell.
What happens in prophase I?DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis. The paired chromosomes are called bivalents, and the formation of chiasmata caused by genetic recombination becomes apparent.
Moreover, during prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. The pairs of replicated chromosomes are known as sister chromatids, and they remain joined at a central point called the centromere.
Therefore, during prophase, the chromosomes in a cell's nucleus condense to the point that they can be viewed using a light microscope. Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures.

The selection that acts over evolutionary time to preserve traits that increase an individual's ability to mate is known as se_xual selection.
What is se_xual selection?The expression 'se_xual selection' makes reference to the type of evolutionary constraint on the individual's ability to mate.
Se_xual selection is fundamental to increase the genetic variation and thus enhance adaptive chances.

Pls answer!!
a) Based on this information and the food chain below, what are the implications of
not taking immediate steps to reduce CO2 emissions in the atmosphere? (2 points)
algae → snails — crabs — salmon → man
b) Because killer whales are at the top of many food chains, it may seem as if they
are not at risk of starving if seals die off. Why is this not necessarily true? (2 points)
Answer:
a) Higher carbon dioxide levels means a rapid growth of Algae, especially toxic blue-green algae that can float to the surface of the water. This growing amount of Algae will expand across the ocean and clutter it. Harmful algal blooms can be harmful to aquatic life, as some produce toxins that can make animals sick, while others can die off in large quantities and deplete oxygen in the water when they decompose. Snails, specifically aqaurium snails, crabs, and salmon do feed on Algae, which could control it to a degree. However, as the ocean becomes more acidic, it could dissolve the shells of crabs and snails, which will cause them to cook in the sun, and therefore die out. As for salmon, studies showed that high CO2 concentrations disturb fish acid-balance, induce stress response, increase nephrocalcinosis incidence, energy metabolism, and feed conversion ratio, and reduces body condition factor, feed intake, and growth. Fish in this condition are very vunerable to dying despite food being all around them. Additionally, fish in those conditions are not suitable for consumption, which means less food for mankind.
b) This is not true. Although they eat sharks, whales, and dolphins, that is just occasional. Seals are their primary meal. As the killer whale is a consumer, it cannot provide food/energy for itself, therefore relying on organisms below it on the food chain. The killer whale predominately consumes seals, being it’s only large predator, killer whales are crucial to the stabilisation of seal population.

what is vegatative propogation?
Answer: Vegetative propagation is an a s exual method of plant reproduction that occurs in its leaves, roots and stem.
Answer:
VEGETATIVE PROPAGATIONregeneration of new plant from the vegetative part or organ of the parent plant is called vegetative propagation vegetative propagation is used full to separate the plant in wider region mother plant get favourable condition if then colonized to the reason by vegetative propagation the offspring adapted
1 NATURAL VEGETATIVE PROPAGATION-
BY ROOT -
the interact root of several Woody plants such as guava sisoo grow just below the soil produce advantages but should just below the soil produce but should develop from this bird which give rise to new plant
BY STEM -
stamp is the source of natural vegetative reproduction in several plants modification or found in stem to perform vegetative propagation
a Runners- the weak stem of creep forward on the soil that downwardly from node axillary bud are present in the axils of scale leaves node
b s ucker - rise time in similar to runner but it is underground its main stem grow upward and develop advantages root from underground
c offset- the thick and fleshy runner of hydrophytes plant is called offset
BY LEAVES
Titan plant develop adventirious bud on their leaves this word after separating from Mother plant give rise to new plant
BY BULBILS
they are fleshy but which are produced in the axils of leaves in the auxiliary Bud
ARTIFICIAL VEGETATIVE PROPAGATION-GRAFTING
it is the most common method of vegetative reproduction in this method variety of shame spices can be converted into plant of better variety in the technique of trade off to plant are joined in such portion of one part called stock is joint with another plant is called scion
BUDDING-
it is the superior and modern method of plant propagation in this method but of plant are superior varieties grafted in the stem of plant in variety after making oblique you cut up to the bark of stem after fue with this but join with plant as result formed on the new plant
LAYERING-
the method of inductor root formation the branches while they are still attached to a mother plant is called layering
CUTTING -
any part of plant root stem or leaf which has the power to develop itself into a new plant after separating from the mother plant is called cutting
IMPORTANCE OF PROPAGATION
the plant which have lost their power to produce seeds like Banana grapes Rose in it can be propagated by vegetative means only the plant which produce seed in less number are usually propagated vegetative leaf the change of some chemical x-ray and environmental variation as temperature can be studied easily in plant which vegetative propagation the tissue culture technique of vegetative propagation is used to raise disease free plantdescribe at least one part of the experiment prodcedure you though was essential for getting good results did you find

Why is it important to design field studies that will not make wild animals associate humans with food?
Animal behaviorists have found that animals gain from developing bonds with trustworthy humans, but doing so calls for a lot of motivation and understanding about the animal's behavior.
What is animal behavior?The scientific study of non-human animal behavior is called ethology, and it often focuses on behavior in natural settings and sees behavior as an evolutionary adaptive quality.
Animal behavior is an animal's response to stimuli, and there are both acquired and intrinsic types of animal behavior.
Dogs who have been trained to obey commands are an example of animal behavior. In contrast, inherent behavior includes mating cues like bird crowing and peacock dancing before a storm.
Animals benefit from forming relationships with dependable humans, according to animal behaviorists, although doing so requires a lot of drive and knowledge of the animal's behavior.
Anyone lacking sufficient motivation or missing the necessary knowledge could suffer considerable harm if they attempted to interact with the animal.
Thus, it is important to design field studies that will not make wild animals associate humans with food.
