Color-blindness results from both the expression of a single recessive sex-linked allele (b.)

Which of the following is a genotype of a colorblind male?



XbY

XBXB

XBY

XbXb

Answers

Answer 1

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.

Using two spring scales students pull on opposite sides of a dynamic card at rest 5 N of force is pulling left in 5 N force is pulling right describe the motion of the card

Answers

Answer:

The card will remain stationary, and will not move.

Explanation:

The card will remain stationary, and will not move because the resultant force acting on the card is equals to zero.

To understand the concept of resultant forces, we can think of a tug of war game. The difference between the forces of the two opposite teams refers to the resultant. It is more like a force imbalance. The team with the higher force wins. If the forces of the teams are equal, the resultant force becomes zero and there is a stalemate.

The same happens in or physical system in which the dynamic card is pulled. Because the two forces pulling the card are equal and opposite, there is a stalemate, and they cancel out each other, thus making the card stationary.

Based on your understanding of evolution, how could you explain why some flowers look like the insects (or birds) that are their primary pollinators? Please help

Answers

Without pollinators, flowers would struggle to thrive since pollinators help with fertilization. It’s possible that the flowers had a selective pressure making them more likely to thrive when they were able to protect their pollinators from predators. (If the flower looks like them, the insects or birds are harder to see so they become harder to eat).

What is Protein?

Proteins are defined as large biomolecules and macromolecules consisting of one or more long chains of amino acid residues. Proteins do most of the work in cells and are essential for the structure, function, and regulation of the body's tissues and organs.

Proteins serve as the building blocks for bones, muscles, cartilage, skin and blood which also form the blocks for enzymes, hormones and vitamins. Proteins are one of the three nutrients that provide calories while the others are fats and carbohydrates.

Alternative Title: primary plant succession

Primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community. This community becomes more complex as new species arrive. Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the community’s ecological structure to an earlier stage.

Primary succession

Primary succession

Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil. The final stage of succession is a climax community, which is a very stable stage that can endure for hundreds of years.

QUICK FACTS

Ecological succession

Pioneer species

Lava-sterilized landscapes, newly formed sand dunes, and rocks either deposited or scoured by retreating glaciers are examples of settings in which primary succession often occurs, because these places either lack soil or their soil cannot sustain life. On newly created volcanic islands, for example, after the rock cools, seeds blown by the wind may lodge in crevices, germinate, and take root. Often these first colonizing plants are weedy species, such as fast-growing grasses and lichens, that do not grow tall but do reproduce quickly. After these plants germinate and grow, they die and decompose, and their remains create pockets of soil in which other plants, as well as fungi, can become established. Over time, such fast-growing vegetation covers more and more of the island, and seeds from other, hardier, taller-growing plants arrive on the wind or are transported by birds that begin to use the island as a stopover during migration.

Surtsey

Surtsey

Surtsey, a volcanic island off the southern coast of Iceland, emerged from the Atlantic Ocean in a fiery eruption in November 1963. Shortly thereafter plants such as sea rocket (Cakile arctica), sand ryegrass (Leymus arenarius), oysterleaf (Mertensia maritima), and seaside sandplant (Honckenya peploides) colonized the island. Much of Surtsey's vegetation is composed of lichens and mosses. However, some higher plants such as the dwarf willow (Salix herbacea) and tea-leaved willow (S. phylicifolia) have grown on the island since the 1990s.

ARCTIC IMAGES/Alamy

These new arrivals shade out sun-loving grasses, shrubs, and other pioneer species, and their cast-off parts decay and add to the soil, altering it by mixing with soil particles left by the decay of earlier plants. More plants and animals arrive (the latter rafting over on flotsam or flying from nearby islands or the mainland), and some become established on the island. The ecosystem changes with each new arrival. Over several decades, the biological community transitions from collections of pioneer and intermediate species to a climax community—that is, a relatively balanced ecological stage whose ecological structure and species composition are far less volatile than those of earlier stages.

Clearly explain the role of mutations in evolution.​

Answers

Answer:

Mutations are changes in DNA and changes in DNA affect all aspects of an organisms life. The first step to evolution is mutation since it creates new DNA sequences for certain genes. By doing so, is creates new allele. The allele is able to spread through reproduction. All genetic features were initially caused by mutations. Mutation is practically the only way in which a species can have a new variation and so, mutations are the raw material of evolution. Although only hereditary mutations cause evolution, mutations have a large impact on evolution.

2. How is the synthesis of ATP in the electron trans-
port chain of mitochondria similar to the syn-
thesis of ATP in chloroplasts?

Answers

Answer:

Explanation:

They’re nearly identical in the actual events of ATP production.

Both take protons that have been ‘pumped’ into a membrane-contained area of the organelle (chloroplast or mitochondrion). These protons flow through the F1/F0 ATP synthase, which does the actual jamming of a phosphate onto ADP to create ATP.

Both pumped those protons by ‘harvesting’ the energy of electrons through passaging those electrons between special protein complexes in a membrane (electron transport chains).

The key differences are in where those energized electrons came from in the first place. In mitochondria, the electrons were ripped from sugar pieces in the Kreb’s/TCA cycle. In photosynthesis, electrons were energized by sunlight (and are then replaced by taking non-energized electrons from water, which is where oxygen is made)
