Which two phrases describe the motion of all the outer planets?

no rotation, slow revolution
fast rotation, slow revolution
north-to-south rotation, slow revolution
no rotation, opposite revolution

Answers

Answer:

B. Fast rotation, slow revolution.

The two phrases that describe the motion of all the outer planets are fast rotation and slow revolution. Therefore,the correct option is B.

Outer planets, such as Jupiter, Saturn, Uranus, and Neptune, have relatively fast rotational speeds, meaning they spin on their axis more rapidly compared to the inner planets like Earth and Mars.

However, their revolution around the Sun is slower, as they are farther from the Sun and require more time to complete one orbit.

All outer planets have a slower revolution around the Sun compared to the inner planets. This is because their larger orbital paths result in longer orbital periods.

Dose mitochondria transfer things to the cell

Answers

Answer:

Yes, mitochondria transfers energy to the cell.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Muscle cells use more energy than most other cells in the body. Because of this, muscle cells must have more mitochondria.

Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

Emma and her younger brother were running a race. After 30 minutes, Emma started feeling pain in her lower leg muscles. a. Suggest the reason for this.

Answers

Answer:

This is due to lactic acid accumulation in Emma's leg muscles.

Explanation:

In the absence of oxygen in the muscle cells, the cell switches from performing aerobic respiration to lactic acid fermentation. The lactic acid fermentation produces lactic acid as a product, which builds up in the muscle cells of the body causing a burning sensation and pain. This often happens during exercises.

This is the cause of Emma's pain in her lower leg muscles. Lactic acid has been formed and accumulated in the muscle cells of her leg during the exercise with her brother.

Why are shadows longer in the morning and evening?
Make sure you give a full, detailed answer, not just one sentence.

Answers

Shadows are longest in the early morning and late afternoon/early evening when the sun appears low in the sky. As the Earth rotates on its axis, the sun hits each location in the morning at an angle. This becomes more vertical as the sun appears to pass more directly overhead around noon.

what is the percentage of calories were absorbed by your system??? Helpppp

Answers

Calories in and of themselves aren't a reliable way of describing energy density in food. It doesn't reflect what actually happens in your body (look up bomb-calorimeter for how people figure out calorie content in foods). So based on this, the question is a bit of a non-sequitur. But if you disregard that and go with a regular answer, it really depends on what kind of calories you're ingesting because foods get digested in a function of different amounts of time. Carbohydrates will get digested and converted into glucose almost immediately - being very close to 100% energy efficiency. Fats are the slowest as your body needs to produce bile in order to digest it - not enough bile = undigested fat = unused calories. Proteins are turned into either amino acids (not an energy source per se) or converted into glucose like carbs but instead through gluconeogenesis which is a less efficient form of glucose conversion than carbohydrates (since your liver/kidneys need to produce the enzymes to convert it). The efficiency of protein is likely in the range of 50-60% calories. This is just the tip of the iceberg though - your metabolism also plays a part as to how much and when these calories are either used, stored, and excreted by your body. Ever got the meat sweats? That's your body burning excess energy through thermogenesis when you eat too much protein. So it really depends why you're asking because the answer will differ for each scenario.

Gametes (SEX CELLS) have ... A. half the number of chromosomes found in the body cells B. twice the number of chromosomes found in body cells C. two sets of chromosomes

Answers

Answer:

A. Half the number of chromosomes found in the body body cells

Explanation:

Somatic (body cells) have 2 sets of chromosomes, while gametes have 1 set of chromosomes. Sperm has one set, and an egg has one set allowing both to fuse to create a new organism.

Answer:

[tex]\boxed {\boxed {\sf A. \ Half \ the \ number \ of \ chromosomes \ found \ in \ the \ body \ cells}}[/tex]

Explanation:

Gametes are sex cells, such as the egg and sperm. They are used in sexual reproduction to produce offspring.

The sex cells are produced during meiosis. The DNA or genetic material is replicated, then the cells divide twice. After this, four haploid cells are produced with half of the genetic material. For example, human body cells have 46 chromosomes but sex cells have 23 chromosomes.

They contain half the genetic material for an important reason. During fertilization, an egg and a sperm fuse. Each one contributes half of the genetic material from the mother or father to create one complete set for the offspring.

Gametes have half the number of chromosomes in body cells and choice A is correct.
