How is energy produced in the sun? Draw a diagram to explain the processes.

Answer:

thus , protons and neutrons are no more indivisible than atoms are ; indeed , they contain still smaller particles , which are called quarks . quarks are as small as or smaller than physicists can measure

Explanation:

Answer:

XbY

Explanation:

because the question asks genotype of a male, the chromosomes would be XY, so XBX and XbXb can be eliminated leaving only XBY and XbY. XBY is incorrect because the question states that colorblindness is represented by lowercase b, so the correct answer is XbY.

Answer:

the second answer choice

25% red, 50% pink, and 25% white

Explanation:

construct a punnett square with the genotype RW and cross them to get genotypes of RR, RW, RW, and WW.

RR is red and occurs once so that is a 25% chance (1/4)

RW is pink and it occurs twice so that is 50% (2/4)

WW is white which occurs once and it is another 25% (1/4)

Explanation:

The DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells is nucleus.

The part of a cell that houses the chromosomes in biology. The membrane-enclosed nucleus is where RNA is synthesised from the chromosomal DNA.

DNA is organised into chromosomes in the nucleus, which is located in the centre of the cell.

The double nuclear membrane (outer and inner) that separates the nucleus from the cytoplasm, known as the nuclear envelope, envelops it. The rough endoplasmic reticulum and the outer membrane are one unit.

The nucleolus' main job is to facilitate ribosome biogenesis by assembling and digesting rRNA into preribosomal particles.

Bacterial cells lack the nucleus, the primary cell structure that houses DNA, that is present in plant and animal cells.

Thus, nucleus is only present is eukaryotic cells.

Answer:

Clean room.

Explanation:

An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).

Hence, a space used in industry or research settings that has a controlled level of contaminants is called a clean room.

A clean room refers to environment or laboratory that is typically free from dust, pollution or any form of contaminants, used for carrying out experiments and manufacturing processes.

Explanation:

Answer:

The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity.

Explanation:

The mass-kinetic energy relationship is ; Directly proportional

The Kinetic energy of an object is directly proportional because an increase in the kinetic energy of a moving object leads to an increase in the mass of the object and also to the increase in the velocity of the object squared.

i.e. K.E ( kinetic energy ) = [tex]\frac{1}{2} mv^2[/tex]

Hence we can conclude  that the mass-kinetic energy relationship is directly proportional.

Answer:

25%

Explanation:

According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.

This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:

30/120 × 100

= 1/4 × 100

= 100/4

= 25% of the selected seeds are infertile.

Answer:

Natural Selection in Real Time

"When we made the comparison between the size of the offspring generation and the population before selection, we found a measured, evolutionary response had taken place and it was almost identical to what we had predicted."

-Peter Grant

Darwin thought that evolution took place over hundreds or thousands of years and was impossible to witness in a human lifetime. Peter and Rosemary Grant have seen evolution happen over the course of just two years.

The Grants study the evolution of Darwin's finches on the Galapagos Islands. The birds have been named for Darwin, in part, because he later theorized that the 13 distinct species were all descendants of a common ancestor. Each species eats a different type of food and has unique characteristics developed through evolution. For example, the cactus finch has a long beak that reaches into blossoms, the ground finch has a short beak adapted for eating seeds buried under the soil, and the tree finch has a parrot-shaped beak suited for stripping bark to find insects.

The Grants have focused their research on the medium ground finch, Geospiza fortis, on the small island of Daphne Major. Daphne Major serves as an ideal site for research because the finches have few predators or competitors. (The only other finch on the island is the cactus finch.) The major factor influencing survival of the medium ground finch is the weather, and thus the availability of food. The medium ground finch has a stubby beak and eats mostly seeds. Medium ground finches are variable in size and shape, which makes them a good subject for a study of evolution.

The first event that the Grants saw affect the food supply was a drought that occurred in 1977. For 551 days the islands received no rain. Plants withered and finches grew hungry. The tiny seeds the medium ground finches were accustomed to eating grew scarce. Medium ground finches with larger beaks could take advantage of alternate food sources because they could crack open larger seeds. The smaller-beaked birds couldn't do this, so they died of starvation.

In 1978 the Grants returned to Daphne Major to document the effect of the drought on the next generation of medium ground finches. They measured the offspring and compared their beak size to that of the previous (pre-drought) generations. They found the offsprings' beaks to be 3 to 4% larger than their grandparents'. The Grants had documented natural selection in action.

While beak size is clearly related to feeding strategies, it is also related to reproduction. Female finches tend to mate with males that have the same size beaks. These factors together can add to the development of new species.

The Grants return each year to Daphne Major to observe and measure finches. They have been collecting data on the finches for over 25 years and have witnessed natural selection operating in different ways under different circumstances.
