What happens to a snail/slug if you pour salt on it? why would this happen?

Answers

Answer:

When you pour salt on a snail/slug the water is very quickly pulled out of the cells of the snail's body by a process called osmosis. As it dries out, the snail's body produces a slimy substance to protect itself. The bubbling comes from the slime and air being forced out of the snail's body as it shrivels up. If enough salt is poured on the snail it will die of dehydration very quickly.

Describe the two stage life cycle of plants: the gemetophyte stage and the sopophyte stage

Answers

Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle.

Why is energy recycling in living systems important?

Answers

Answer:

All living organisms need energy to grow and reproduce, maintain their structures, and respond to their environments. Metabolism is the set of life-sustaining chemical processes that enables organisms transform the chemical energy stored in molecules into energy that can be used for cellular processes Please mark it the brainliest

Explanation:

Please help :( this is a really complicated question

Answers

Answer:

B. exponential growth.

Explanation:

Since the conditions are ideal and the reproducing organisms increase in numbers with every generation this means that it is exponentially growing. It can't be carrying capacity. It is not a logistic growth. And they don't have competition here so it can't be competition.

Crust:crust is the outermost layer of a planet. The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks. The crust is underlain by the mantle,Temperature: Typically in the range from about 500 °C (900 °F) to 1,000 °C (1,800 °F)

Mantle: The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer,Temperature: From
1000° Celsius (1832° Fahrenheit)

Outer Core: Is mostly composed of liquid iron and nickel,Temperature: between 4,500° and 5,500° Celsius

Inner Core: The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles,Temperature: is about 5,200° Celsius

Describe the following types of cell signaling:

Autocrine:

Juxtacrine:

Endocrine:

Paracrine:

Answers

Answer:

Autocrine =  Autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell.This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.

Juxtacrine =  Juxtacrine signalling (or contact-dependent signalling) is a type of cell–cell or cell–extracellular matrix signalling in multicellular organisms that requires close contact.

Endocrine = Endocrine signaling occurs when endocrine cells release hormones that act on distant target cells in the body. Endocrine signaling can be distinguished from two other types of signaling: neural signaling and paracrine signaling. ... Neurons are connected to their target cells via synapses.

Paracrine = Paracrine signaling is a form of cell signaling or cell-to-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behaviour of those cells.

In an experiment, a scientist isolates mitochondria from living cells and suspends them in two different buffered solutions. One solution is maintained at pH 4, while the other solution is maintained at pH 9. The
scientist finds that mitochondria in the solution at pH 4 continue to produce ATP but those in the pH 9 solution do not
The results of the experiment can be used as evidence in support of which of the following scientific claims about mitochondrial activity?
Mitochondria in a cell free environment are unable to convert thermal energy into ATP.
The electron transport chain pumps electrons from the cytosol to the mitochondrial matrix,
CATP production in mitochondria requires a hydrogen ſon gradient that favors movement of protons into the mitochondrial matrix.
D
ATP synthase molecules change their orientation in relation to the proton gradient across the mitochondrial membrane.

Answers

Answer:C

Explanation:

The scientific claim 'ATP production in mitochondria requires a hydrogen ion gradient that favors the movement of protons into the mitochondrial matrix' SUPPORTS mitochondrial activity (Option C).

Cellular respiration is defined as a group of metabolic reactions by which cells can generate ATP (the energy coin of the cell), by using oxygen and the energy released in the chemical bonds of foods (e.g., glucose).

Cellular respiration has three main types of reactions: glycolysis, the acid citric cycle and oxidative phosphorylation.

Glycolysis occurs in the cytoplasm, whereas the citric acid cycle and oxidative phosphorylation occur in the mitochondria.

During oxidative phosphorylation, the movement of electrons through a series of carriers is coupled to the generation of an electrochemical proton (H+) gradient across the inner mitochondrial membrane.

Subsequently, this proton (H+) gradient is then used to generate ATP by using an ATP synthase.

In conclusion, the scientific claim 'ATP production in mitochondria requires a hydrogen ion gradient that favors the movement of protons into the mitochondrial matrix' SUPPORTS mitochondrial activity (Option C).
