Explain why a sugary gummy bear changes in size after being soaked in salt water?

Biology
1 answer:
galben [10]3 years ago
8 0

Answer:

If you have already soaked it in tap or distilled water, it is very large. Soaking it in salt water will cause it to shrink because there is now a high percentage of water in it, and not a lot of salt. The salt from the water gets absorbed by the bear. Now, the water percentage has decreased, so it is not as large. However, the gummy bear will never change back into its original form.

What is the function of the subplate neurons? Choose the correct option.
Semmy [17]

Answer: C) The subplate neurons attract the appropriate thalamic axons to the different parts.

Explanation:

Subplate neurons are the first developed neurons can be found in the cortex of mammals. These neurons disappear during the process of postnatal development and due to functional maturation.

These neurons are sensitive to the injury, when the humans experience cognitive and motor defects.

These neurons attract the thalamic axons and receive the synaptic inputs through the thalamic axons thus helps in establishing the link between the thalamic axons and the target layer IV. The signals are distributed from the thalamic axons to different parts of the body.

Are Sarcomeres made of amino acids?
nevsk [136]

Answer:

A titin mutation that occurs in muscular dystrophy with myositis (mdm) mice results in a predicted 83 amino acid deletion in the N2A and PEVK regions of the titin protein. Muscles from mdm mice are actively more compliant  possibly owing to the deletion in titin's I-band region. This suggests that modulation of titin stiffness in active sarcomeres by the proposed titin–thin filament interaction may be affected by the mdm mutation. The answer is YES I believe.

Explanation:

I believe the answer is yes from my deep reaserch. You may want to research in your texts book/lesson or courses and review what your teacher/professer has given you.

Why is it necessary to have a constant input of energy into an ecosystem?
IrinaK [193]
If there was not a constant Input of energy into the ecosystem then nothing would have the power to do anything and nothing would be alive. the energy starts with the sun, then goes to plants, then animals that eat the plants, and then the animals that eat those animals, Ect. if this chain reaction did not happen then the plants wouldn't have to power to go through photosynthesis and then we would get no energy. the amount of energy lessen with every chain that it goes through, this is why we get more energy eating plants and why they are healthier.
