Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes. While pouring an unknown chemical into a beaker, she accidently splashed some of the chemical in her eyes. What should Maria immediately do next?

Answers

Answer:

She should immediately rinse or flush her eyes with water.

Explanation:

One of the most important precautionary measure to be taken when working with explosive chemicals in the laboratory is the use of safety goggles. However, in this case, Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes.

Maria accidentally splashed some chemicals into her eyes while trying to pour it into a beaker. The primary or initial response to this happening is to immediately FLUSH OR RINSE her eyes with water. This will flush away the chemical from her eyes before it can have its detrimental effect.

Answer:

proceed to the eye wash station, open her eyes, and rinse them for at least 15 minutes

How are mid-ocean ridges formed at divergent tectonic plates?

The plates are moving in a zigzag formation, creating shallow earthquakes which forms a mid-ocean ridge.
Mid-ocean ridges are not resulting features of ocean-to-ocean divergent boundary zones.
The plates are moving towards each other, which causes the crust to buckle and push upwards or sideways which forms a mid-ocean ridge.
The stretching lithosphere is pushed up as the plates move apart.

Answers

Answer:

The stretching lithosphere is pushed up as the plates move apart.

Explanation:

Mid-ocean ridges are basically underwater mountains that are created with the help of lava convection (which causes the rising of plates) and the diverging (the pulling away) of tectonic plates. This is also how ocean floor spreading happens.

I know that mountains are formed by the converging of tectonic plates, but ocean ridges are NOT created like this.

B.The hermit crab uses a leftover mollusk shell as a home. His shell is part of his niche.
C.The crow is a quite adaptable organism and has a broad niche.
D.One aspect of a sloth's niche is the type of food it eats.

Answers

Answer:

a i think

Explanation:

The following statements about niches are false: The crow is a quite adaptable organism and has a broad niche, which is option C, as the niche is not a broad place but a place where the individual spends most of the time living and reproducing.

What exactly are "niches"?

A niche is the place that an organism plays in its environment, including the physical space it occupies and the resources it uses, and it is the way that an organism interacts with its environment and with other organisms, whereas niches can be occupied by many different types of organisms, and in some cases, different organisms may even occupy the same niche at the same time, which is known as niche overlap.

Hence, the following statements about niches are false: Option C is the crow, which is a highly adaptable organism with a wide niche.

1. List five organelles eukaryotes have that prokaryotes do not have.
2. Explain how the following organelles ensure that a cell has the proteins it needs: nucleus, rough ER, vesicles,
and Golgi apparatus.
3. What is the main difference between rough endoplasmic reticulum and smooth endoplasmic reticulum?
4. Describe the three types of vesicles.

Answers

Answer:   1 Lysosomes and peroxisomes, Microtubules, Endoplasmic reticulum, Mitochondria

2 The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.

3 The rough endoplasmic reticulum has ribosomes on its surface. This is what give the RER a "rough" appearance.            The smooth endoplasmic reticulum (SER) does not contain ribosomes. The Smooth ER looks more like tubes. The SER helps in the storage of proteins and lipids.

4 Secretory vesicles contain materials that are to be excreted from the cell, such as wastes or hormones.

Transport vesicles move molecules within the cells.

Vacuoles are vesicles that contain mostly water.

explain how pH and temperature can affect enzyme activity
Please help has to be due in 20 mins. Thank you for helping me.

Answers

Answer:

Enzyme activity depends on many factors such as Substrate concentration, enzyme cofactor, enzyme inhibitors, pH, and temperature. pH and temperature are two important factors that directly affect the activity of an enzyme as follows:

1. pH

Each enzyme has the specific optimal pH that allows it to perform its function to its fullest. The enzymes are the protein made up of the interaction of the hydrogen bond in the side chain of the protein. if there is any change from optimum pH, the enzyme activity decreases until it stops working.

2. Temperature:

Each enzyme has its own optimal temperature. Any modification or change in temperature results in the activity of an enzyme, and it also leads to the denaturation of an enzyme as it is made up of protein.

What is the dynamic of type 1 diabetes process concerning cellular disruption and what is its effect on the major body systems?

Please help, will give brainliest

Answers

Explanation:

Type 1 diabetes occurs when some or all of the insulin-producing cells in the pancreas are destroyed. This leaves the patient with little or no insulin. Without insulin, sugar accumulates in the bloodstream rather than entering the cells. As a result, the body cannot use this glucose for energy.

In most people with type 1 diabetes, the body's immune system, which normally fights infection, attacks and destroys the cells in the pancreas that make insulin. As a result, your pancreas stops making insulin. Without insulin, glucose can't get into your cells and your blood glucose rises above normal.18-
