Natural selection causes changes in? A.genotypes. B.populations. C.individuals. D.phenotypes.

Answers

Answer:

populations

Explanation:

A) genotypes

Natural selection may happen because of different genotypes (for example, heterozygous individuals survive better). Natural selection does not change genotype.

Recall that genotype is the type of alleles one has.

B) populations

Natural selection is the survival of the fittest. For example, a drought. Or predators. Or limited food supply. Or overproduction. All will end up with the stronger, better-surviving types of a certain population. Natural selection does change populations.

C) individuals

Natural selection usually occurs when there are large amounts of a certain type of individual (for example, bunnies). They usually do not affect individuals.

D) phenotypes

Natural selection may happen because of different phenotypes (for example, green grasshoppers survive better than red ones). Natural selection does not change phenotype.

Recall that phenotype is the physical appearance one has.

Extra:

Phenotype vs. Genotype:

If A is dominant for brown hair and a is recessive for albino hair:

Genotype Aa has a phenotype of brown hair.

Genotype AA has the phenotype of brown hair.

Genotype aa has the phenotype of albino hair.

You can see how genotype and phenotype are like.

Natural selection causes changes in populations. The correct option is B.

What is natural selection?

Natural selection is a biological mechanism that allows some organisms to survive and reproduce more successfully than others, resulting in the transfer of advantageous traits from one generation to the next.

Natural selection operates on the and phenotype genotype of the organism. It causes changes in the frequency of genes (genotype) in a population, which results in changes in the physical appearance (phenotype) of the population.

A population is a group of individuals of the same species living in the same geographical area at the same time. Natural selection affects populations, not individuals, as it occurs over several generations, and it results in changes in the allele frequencies in the population. Thus, natural selection causes changes in populations.

Therefore, the correct option is B.

What is the function of; 1.plumule,
2.embryo,
3.hilum,
4.microphone
5.and cotyledon?​

Answers

Answer:

1=Function of Plumule (shoot tip): The plumule is the part of the embryo that develops into the shoot bearing the leaves of the plant. The plumule gives rise to aerial shoots. The function of cotyledon: They store reserve food material or serve as photosynthetic organs in young seedlings.

2=An embryo is the early stage of development of a multicellular organism. In general, in organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization and continues through the formation of body structures, such as tissues and organs.

3=. In botany, a hilum (pronounced /ˈhaɪləm/) is a scar or mark left on a seed coat by the former attachment to the ovary wall or to the funiculus (which in turn attaches to the ovary wall). ... The adjectival form hilar denotes the presence of such a mark, and can be used as a distinguishing characteristic of a seed or spore........!!!!!

4=A microphone is the device responsible for transferring sound as it travels through the air, and converting it into electrical impulses that can be amplified by PA systems, or recorded by either analog or digital recorders.

5= Cotyledons help supply the nutrition a plant embryo needs to germinate and become established as a photosynthetic organism and may themselves be a source of nutritional reserves or may aid the embryo in metabolizing nutrition stored elsewhere in the seed.

Explanation:

Recuerde que pH = -log [H ^ +]

Sea la concentración de iones de hidrógeno [H ^ +]

Si es así, entonces;

Por lo tanto;

[H ^ +] = Antilog (-pH)

Which statement best describes the importance of wisdom teeth to human evolution?

A. They are vestigial structures that once performed an important function for human ancestors.

B.They are evidence that humans have never evolved.

C. They are vestigial structures that never performed a necessary function for human
ancestors.

D.They are evidence that humans cannot evolve.

Answers

Answer:

A

Explanation:

There's a reason they grew there in the first place. The Caveman mouth was much larger than our modern mouths.

The statement that best describes the importance of wisdom teeth to human evolution is that they are vestigial structures that performs function for human ancestors.

What do you mean by Evolution?

Evolution may be defined as the change in the characteristics of a species over several generations and relies on the process of natural selection.

Wisdom teeth are evolved in humans because early humans needed to chew coarse, hearty foods, they required a broader jaw. Wisdom teeth grew in to give them more chewing power for this purpose.

By definition, at STP (Standard Temperature and Pressure), any gas takes up a volume of 22.4L.

Consequently, because the ideal gas law (PV=nRT) states that the number of moles is directly proportional to the volume of the gas, 2.7M of N2 takes up a volume of:

To model ocean water in different places on Earth, a student pours equal amounts of water in two containers. He adds the same amount of salt to each container and stirs until the salt is completely dissolved. He places Container 1 in a cool place in the house and Container 2 outside in the sunlight. After two hours, he tests the salinity of water in each container. What should the student MOST LIKELY conclude, and why?

Answers

Answer:

The correct answer would be - container 2 will have less salinity than container 1.

Explanation:

The given experiment can give an idea about how the temperature of surroundings can affect the salinity, volume, and density of the water that has the same amount of water and salt dissolved in it. The independent variable or the only variable that is different is their place that has a difference in the temperature. Container 1 is placed in a cool place while container 2 is placed in sunlight.

We know that the warmer the water it takes more space so, therefore, less density. Density and salinity both have a positive relationship so an increase in density increases the salinity and vice versa. Thus, here the salinity of container 2 would be low in comparison to container 1

One map shows rates in 2007 and the second shows unemployment rates in 2009. A map key shows that gray represents 16.5 percent or greater unemployment, purple represents 13.1-16.4 percent unemployment, dark red represents 11.0 - 13.0 percent unemployment, bright red represents 8.9-10.9 percent unemployment, dark orange represents 7.1-8.8 percent unemployment, light orange represents 5.5-7.0 percent unemployment, bright yellow represents 4.1-5.4 percent unemployment, white represents 4.0 percent or lower unemployment. The 2007 map shows a large portion of the Midwest in white. The west coast is largely yellow and orange. The east coast and central part of the U.S. are also largely yellow and orange. There are a few scattered splotches of red, and a very few purple and gray areas. The 2009 map is dramatically different. It shows a large area of the central U.S. and most of the west coast in red, dark red, purple and gray. There are now very few white areas on the entirety of the map. The Midwest still has the lowest unemployment, but much of it is now yellow and orange. Public Domain It has been argued that elected officials are less likely to be reelected if the unemployment rate increases during their term in office. If this is true, which statement is supported by the maps above? Candidates running for reelection in 2009 were less likely to win their races. Candidates running for office in 2009 were highly unlikely to be impacted by unemployment rates. Candidates running for office in 2007 were highly likely to be impacted by unemployment rates.
