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.
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.

Select one:
A. Plants store genetic information in the nucleus of their cells
B. Plants are motile primary consumers
C. Plants are multicelular
D. Plants are autotrophic
Answer:
D. Plants are autotrophic
Explanation:
Both plants and animals are eukaryotic, meaning they contain a nucleus with genetic information, so that crosses out A. I don't know what motile primary consumers are. Assuming, they're primary consumers, primary consumers are those that eat producers, so in this case, this would elminate B. Both plants and animals are multicellular. Plants ARE autotrophic, meaning they produce their own food. Animals, however, have to get their own food, either by hunting or scavaging. Floods begin as...

Dose mitochondria transfer things to the cell
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.

What is the name given to your gag reflux organ?
Answer: pharyngeal reflex
Explanation:
The gag reflex, also known as the pharyngeal reflex, is when your pharynx contracts and your larynx pushes up, contracting your throat.
The afferent limb of the reflex is supplied by the glossopharyngeal nerve (cranial nerve IX), which inputs to the nucleus solitarius and the spinal trigeminal nucleus. The efferent limb is supplied by the vagus nerve (cranial nerve X) from the nucleus ambiguus.

Answer:
Visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
Explanation:
Visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays are types of energy that travel from sun to earth. These types of energy are present in the solar radiation that coming from the sun. Visible light is important for the plants because plants use this visible light in the process of photosynthesis while on the other hand, Ultraviolet light filters by ozone layer that surrounded the earth. This Ultraviolet light is dangerous for humans and animals .

a muscle contracting and pulling the hand away is shown by _______________.
A) sensory neuron
B) motor neuron
C) interneuron
Answer:
So the answer would be B motor neuron
Explanation:
Because this is a movement it goes with the word motor so that is how I solved this.
Answer: B
Explanation:
The sensory neurons pick up impulses and passes it to the relay neurons which takes the information to the motor neurons which in turn causes the muscles to contract.
Interneurons are found in the central nervous system and carries impulses from one neuron to the other. So the answer is definitely B.

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
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.

describe how scientists would have to use to classify M.smithii into archea domain
pls help asap
Explanation:
Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla
Answer(Explanation):
Methanobrevibacter smithii is the predominant archaeon in the microbiota of the human gut. M. smithii has a coccobacillus shape. It plays an important role in the efficient digestion of polysaccharides by consuming the end products of bacterial fermentation.
Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla.
