The fruit fly represented in the diagram below has unusual, curled wings that formed after exposure to radiation. In order for the fly to pass this trait on to its offspring a change has to occur

Answers

Answer:

the gametes of the fly

Explanation:

i took the test and got this question right

I'm not sure what the question is, but the only traits that are passed down are the ones that can be found in the germ (sex) cells. Radiation exposure alters somatic (body) cells usually, but can also alter germ cells, so it depends.

Read and analyze the Ecosystem Response section and list the negative feedback mechanisms that keep the bay ecosystem above its steady state.

Answers

Answer:

Increase occurs in fresh water input.

Decrease occurs in the salinity of the bay.

Explanation:

The low rate of fresh water input and the presence of high amount of salts in water decreases the population of producers such as grasses in bay ecosystem. Due to this decrease, the population of the marine animals decreases due to the low availability of food for herbivorous organism that lives in the bay. The negative feedback mechanisms will be achieved if increase occurs in fresh water input and decrease occurs in the salinity of the bay.

If the asthenosphere cooled and stopped flowing. How would you expect the movement of tectonic plates in the lithosphere to change? The tectonic plates would _________?

Answers

If the asthenosphere cooled and stopped flowing. The movement of tectonic plates in the lithosphere changes. The tectonic plateswould move less than 2 cm a year.
> The asthenosphere is the highly viscous, mechanically weak and ductilely deforming region of the upper mantle of the Earth.

Photosynthesis and cellular respiration are processes that create for the cell.

Answers

Answer: Both processes create energy. Photosynthesis creates glucose (energy from the sun is converted to chemical energy) and oxygen for the cell while cellular respiration creates energy for the cell.

Explanation: Photosynthesis and cellular respiration are two important processes. Photosynthesis occurs only in plants while cellular respiration occurs in both plants and animals.

In photosynthesis, plants use carbon dioxide, water and sunlight to produce glucose and oxygen while in cellular respiration both plants and animals breakdown glucose in the presence of oxygen to produce carbon dioxide, water and energy. The light energy conserved in glucose during photosynthesis is broken down during cellular respiration to release chemical energy.

The chemical equation for photosynthesis is 6CO2+ 6H2O + sunlight --> C6H12O6 + 6O2.

The chemical equation for cellular respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy. The energy produced in cellular respiration is used to carry out other cellular processes.

Photosynthesis occurs in the chloroplast which is an organelle found only in plant cells while cellular respiration occurs in the mitochondria.

Photosynthesis uses carbon dioxide and water produced in cellular respiration while cellular respiration uses glucose and oxygen produced in photosynthesis. This means that the two processes depend on each other for the supply of its reactants.

Which of the following animals possess a central nervous system? jellyfish lobsters fish starfish

Answers

The answer is fish.

A central nervous system is a common characteristic among vertebrates, including fish. It receives information, integrates them, coordinate the activity of the body. In fish, the central nervous system consists of the brain, medulla oblongata, and spinal cord.

Jellyfish has a nerve net that surrounds its whole body. The nerve net consists of interconnected nerve cells. Lobster has a nervous system made up of ganglia. Starfish has no brain. Its nervous system consists of a nerve ring around a mouth and radial nerves that run out of the ring.

Final answer:

Lobsters, fish, and starfish possess a central nervous system, while jellyfish do not.

Explanation:

The animals that possess a central nervous system from the given options are lobsters, fish, and starfish.

Jellyfish lack a true brain and have a system of connected nerve cells called a 'nerve net,' which is not considered a central nervous system.

Lobsters, fish, and starfish have a centralized nervoussystem, with lobsters and fish having a more complex organization of neurons including a brain, ganglia, and nerve cords.
