B) sometimes when there is a drought or phenomena in living area so people living there might face issues with the resources they had and now they are gone.so right thing is to move from that place to ankther place where there is resources

C)in areas that are near to desert or hilly areas might not have enough resources near them. so that may cause people to spent money to bring that resources near them or energy waste will be there.so in that cases they should either renovate that place for living or not to live there.

Texto donde se desarrolle la definicion de seleccion natural. Además, empleem los siguientes terminos: Variabilidad, mecanismo selectivo y Darwin.

Answers

Answer:

la selección natural es el mecanismo principal por el cual la evolución ocurre

Explanation:

Charles Darwin fue un naturalista inglés que propuso la teoría de la evolución o 'descendencia con modificación' mediante el mecanismo de selección natural. Acorde a esta teoría, la selección natural se define como el mecanismo selectivo de reproducción diferencial de los individuos mejor adaptados a su ambiente. La variabilidad es el la materia prima sobre la cual la selección natural actúa, seleccionado aquellos individuos que presentan combinaciones fenotípicas y genotípicas más adaptadas para sobrevivir en un ambiente en particular. Los individuos de una población que son 'superiores adaptativamente' poseen más chances de sobrevivir y reproducirse, y por lo tanto tienen también más probabilidades de transmitir sus genes a la siguiente generación.

Explanation:

Some male peakcocks used to have bright and large tails while others had dull, smaller tails. Female peacocks will only mate with the ones that have the brightest and largest tails. Explain how this would impact the offspring of male peacocks over time.

Answers

Answer:

Over time, most males will have bright and large tails. Females only mate with males carrying these traits, and so natural selection will favor them.

Explanation:

Bright and large tails are traits that reflect the genetic quality of males. So individuals with the most vibrant color and length express better capabilities of finding food, competing for resources, competing for males, among others, are the best option to mate and to ensure successful offspring.

The brightest and largest tails are, the better chances males have to mate and pass their genes to the following generations. So the organism spends energy and resources to produce more vibrant colors and longer feathers to enhance mating chances.

Females must ensure their reproductive success, so sexual selection is the pressure modeling males in this species. Females will only choose individuals with the better genetic charge to mate -individuals with brightest and largest tails-, so their progeny can have better genes and higher survival probabilities.

Males with the brightest and largest tails will mate and reproduce. They will pass their genes to their progeny. Male offspring will also have bright and large tails because they inherit these conditions from their parental. These male offspring will also pass their genes to the progeny, and so on. The frequency of the alleles that express these traits will increase in the population. Natural selection is favoring these alleles. So over time, there will be much more individuals with bright and large tails than individuals with dull and small tails.

Explanation:

The lytic cycle is one of the two cycles of viral reproduction, the other being the lysogenic cycle. The lytic cycle results in the destruction of the infected cell and its membrane. Now during the lytic cycle of virulent phage, the bacteriophage takes over the cell, reproduces new phages, and destroys the cell. T-even phage is a good example of a well-characterized class of virulent phages.

Answers

Answer:

A logging company reseeds and replants in a forested area after cutting down trees for timber

Explanation:

Answer:

Sustainability is the capacity to endure in a relatively ongoing way across various domains of life.[1] In the 21st century, it refers generally to the capacity for Earth's biosphere and human civilization to co-exist. It is also defined as the process of people maintaining change in a homeostasis-balanced environment, in which the exploitation of resources, the direction of investments, the orientation of technological development, and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations.[2][failed verification] For many in the field, sustainability is defined through the following interconnected domains or pillars: environmental, economic and social,[3] which according to Fritjof Capra,[4] is based on the principles of systems thinking. Sub-domains of sustainable development have been considered also: cultural, technological and political.[5][6] According to Our Common Future, sustainable development is defined as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs."[7][8] Sustainable development may be the organizing principle of sustainability, yet others may view the two terms as paradoxical (seeing development as inherently unsustainable).[9]

Answers

Answer:

D. 367

Explanation:

If a roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates, it contains 367 calories of energy, hence option D is correct.

What is food energy?

Animals obtain the chemical energy known as "food energy" from their food in order to maintain their metabolism, which includes their muscular activity.

The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.

To find the total calories, multiply the given biomolecules grams with their calorie count.

= 42 × 4 + 7 × 9 + 34 × 4

= 168 + 63 + 136

= 367 calories

Therefore, the sandwich provides 367 calories of energy, if it contains 42 g protein, 7 g fat, and 34 g carbohydrates.
