Your brother recently joined the football team. He feels tired after each days practice and
is unable to continue with his homework. Is there a connection between his tiredness and
nutrition he takes? If yes, give reason, also design a healthy diet plan for him.

Answers

Answer:

from view,I will go with yes because it depends on the food he eats whether it is balanced or not. for example,if he eats only vitamin foods and carbohydrates there won't be enough energy for him go pass the day.

Yes, there is probably a link between your brother's dietary habits and his fatigue level.

Football practice can be a physically taxing and energy-intensive activity. Your brother may feel tired and struggle to maintain energy levels if he is not getting enough nutrition to support his increased energy expenditure. When creating a healthy diet plan for your sibling it is important to focus on providing adequate nutrition to support your sibling's athletic performance and recovery. Here is a dietary recommendation:

Include whole grains (such as brown rice, quinoa and whole wheat bread), fruits and vegetables in your diet to get enough carbohydrates to last you all day.

Include sources of healthy fats, such as avocados, nuts, seeds and olive oil, to help supply essential fatty acids and keep you feeling full.

Hydration: To maintain hydration levels, be sure to consume enough fluids before, during and after exercise.

Snacks: To replenish nutrients and give you energy after exercise, eat healthy snacks, such as yogurt, mixed nuts, fresh fruit and granola bars.

Encourage your sibling to prioritize nutrient-dense foods that offer a balanced balance of carbohydrates, proteins and fats, and to eat frequent meals, especially breakfast.

g Two closely related species of plant (A and B) hybridize to form a new species (C). Species A is diploid and has 8 chromosomes. Species B is tetraploid and has 20 chromosomes. -What type of whole genome duplication is this (autopolyploidy or allopolyploidy)

Answers

Answer:

allopolyploidy

Explanation:

Polyploidy is the condition by which a cell might have more than two chromosome sets that form homologous pairs. It might occur due to a failure or abnormality in cell division.  

Autopolyploidy

Refer to a type of polyploidy in which an organism has more than two copies of homologous chromosomes. It results from the duplication of a group of chromosomes of the same species. Autopolyploid individuals have at least three groups of homologous chromosomes. Autopolyploidy is produced by the gamete fusion of the same progenitor - same species-, duplicating the number of chromosomes of diploid species. The autopolyploid cell has groups of homologous chromosomes. Autopolyploidy is produced mainly due to non-disjunction during meiosis.

Allopolyploidy

Refer to another type of polyploidy in which species have more than three sets of chromosomes in their cells. Allopolyploidy occurs when two different species mate, leading to the fusion of gametes that belong to different species and produce a new hybrid. The chromosomic complement has more than two copies of chromosomes. The hybrid is infertile with the parental species. The allopolyploid cells have chromosome groups that are not homologous.  

In the exposed example two different species mate and produce a hybrid species.

What did Ari draw?

a food chain
a trophic chain
a food web
an energy web

Answers

Answer: Ari draw a food web.

Explanation:

A single ecosystem which contains all the food chains is called a food web.

In a food web each living thing present in a food web is a part of multiple food chains. Hence, food webs tend to represent the overlapping of food chains in that ecosystem.

The flow chart drawn by Ari represents that the living things present in cycle 1 are part of cycle 2 and cycle 3. Also, living things present in cycle 2 are part of cycle 1 and cycle 3.

A food chain is basically a single path where each organism is dependent of the other as a source of food without any overlapping.

Thus, we can conclude that Ari draw a food web.

Explanation:

Skeletal muscle cells essentially engage in large shape changes to pull on bones to create movement. To do this shape change, skeletal muscle cells require a lot of energy and the production of a lot of protein used inside the cell to make the structures that change the shape. Name 3 organelles that would be important in this function (one for each function).

Answers

Answer:

Explanation:

1) The mitochondrion : is an organelle that makes energy available to the cell. They use energy from organic compounds (such as glucose) to make molecules of ATP (adenosine triphosphate).

2) Ribosomes: are small structures where proteins are made. Both subunits consist of proteins and RNA. RNA from the nucleus carries the genetic code, copied from DNA, which remains in the nucleus. At the ribosome, the genetic code in RNA is used to assemble and join together amino acids to make proteins. Ribosomes can be found alone or in groups within the cytoplasm, as well as on the RER.

3) Cytoskeleton: is the “frame” of the cell, keeping structures in place, providing support, and giving the cell a definite shape.The cytoskeleton organizes the cell and keeps the cell’s organelles in place, but it also aids in the movement of organelles throughout the cell.

Answers

Answer:

- Typically begins about 20 minutes after stage 1: Stage 3

- Alpha waves dominate: Stage 1

- Sleep spindles occur: Stage 2

- Light sleep: Stage 2

- Vital signs are at their lowest levels: Stage 4

- Delta waves dominate: Stage 4

- Feeling a drifting sensation: Stage 1

- Beginning of decline in respiration and blood pressure: Stage 2  

Explanation:

Sleep can be divided into two phases: 1-non-rapid eye movement (NREM) sleep and 2-rapid eye movement (REM) sleep. In turn, NREM sleep is divided into four stages (1 to 4). Stages 1-2 are referred to as “light sleep”, while stages 3-4 are known as “deep sleep”. The first NREM stage (normal length: 5-10 minutes) is the transition between wakefulness and sleep. During this stage, the brain produces high amplitude theta waves. During the second NREM stage (light sleep, 10-25 minutes), the body temperature drops, muscles are in a more relaxed state, the breathing and heart rate also drop. The third NREM stage (20-40 minutes) involves the emergence of delta waves and muscles are entirely relaxed. This period (stage 3) is a period of deep sleep, which is referred to as slow-wave sleep (SWS). Finally, the fourth NREM stage (10-60 minutes) is characterized by high amplitude delta waves, while heart and respiration rates slow dramatically.

Answers

Answer:

Advanced forms of life existed on earth at least 3.55 billion years ago. In rocks of that age, fossilized imprints have been found of bacteria that look uncannily like cyanobacteria, the most highly evolved photosynthetic organisms present in the world today. Carbon deposits enriched in the lighter carbon-12 isotope over the heavier carbon-13 isotope-a sign of biological carbon assimilation-attest to an even older age. On the other hand, it is believed that our young planet, still in the throes of volcanic eruptions and battered by falling comets and asteroids, remained inhospitable to life for about half a billion years after its birth, together with the rest of the solar system, some 4.55 billion years ago. This leaves a window of perhaps 200-300 million years for the appearance of life on earth.

divine interventionThis duration was once considered too short for the emergence of something as complex as a living cell. Hence suggestions were made that germs of life may have come to earth from outer space with cometary dust or even, as proposed by Francis Crick of DNA double-helix fame, on a spaceship sent out by some distant civilization. No evidence in support of these proposals has yet been obtained. Meanwhile the reason for making them has largely disappeared. It is now generally agreed that if life arose spontaneously by natural processes-a necessary assumption if we wish to remain within the realm of science-it must have arisen fairly quickly, more in a matter of millennia or centuries, perhaps even less, than in millions of years. Even if life came from elsewhere, we would still have to account for its first development. Thus we might as well assume that life started on earth.

How this momentous event happened is still highly conjectural, though no longer purely speculative. The clues come from the earth, from outer space, from laboratory experiments, and, especially, from life itself. The history of life on earth is written in the cells and molecules of existing organisms. Thanks to the advances of cell biology, biochemistry and molecular biology, scientists are becoming increasingly adept at reading the text.

An important rule in this exercise is to reconstruct the earliest events in life's history without assuming they proceeded with the benefit of foresight. Every step must be accounted for in terms of antecedent and concomitant events. Each must stand on its own and cannot be viewed as a preparation for things to come. Any hint of teleology must be avoided.
