4. If an atom has five protons, how do you know that it has five electrons as well?​

Answers

Answer 1

Answer:

Atoms are neutral in electrical charge because they have the same number of negative electrons as positive protons (Table 4.5. 1). Therefore, the atomic number of an atom also tells you how many electrons the atom has.

Explain how an appliance could have a lower wattage than another but still cost more per year for electricity. give examples

Answers

Answer:

An appliance could have a lower wattage than another but still cost more per year for electricity if it’s not well insulated and cycling on more often to keep the interior cold. For instance, a cheap mini fridge may have low wattage, but if it’s not well insulated and cycling on more often to keep the interior cold, your final costs to run it will be higher than a better-designed beverage cooler with excellent insulating properties.

What does lightning contribute to that can ultimately help local ecosystems recycle nutrients in the soil?
Noise pollution
Wildfires
Migratory navigation for birds
Heat in local bodies of water

Answers

Lightning can contribute to wildfires, which can ultimately help local ecosystems recycle nutrients in the soil. When lightning strikes a tree, it can start a fire that burns dead and decaying matter on the forest floor, releasing nutrients like nitrogen, phosphorus, and potassium back into the soil. These nutrients can then be absorbed by plants and used to fuel new growth. The ash left behind by the fire can also enrich the soil with essential minerals that are beneficial for plant growth.

While wildfires can be destructive and dangerous, they are also a natural part of many ecosystems and can help to maintain their health and diversity. In some cases, wildfires are even intentionally set by land managers to promote ecosystem health and reduce the risk of more dangerous fires in the future.

Therefore, while lightning itself does not directly contribute to nutrient recycling in the soil, it can indirectly do so by starting wildfires that help to maintain healthy ecosystems.

Which of the following landforms results from erosion by glaciers and flowing water

Answers

A cirque is a landform that results from erosion by glaciers and flowing water. A cirque is a bowl-shaped hollow that is located at the head of a glacier valley, with a steep back wall and a shallower slope towards the front. Glaciers erode rock by plucking and abrasion, and cirques are formed when the ice plucks out the rock at the head of a valley, leaving a hollow depression. Water from melting glaciers and snow collects in the cirque and may form a lake. Over time, the cirque may erode further, creating a larger basin-shaped valley called a glacier trough.

flower structure and functions and cross pollination

Answers

The flower is the reproductive structure of angiosperm and has four main parts: the calyx, corolla, stamens, and pistil. Cross-pollination occurs when pollen from one flower fertilizes the ovules of another flower.

The calyx and corolla protect the reproductive organs and attract pollinators with their colors and fragrance. The stamens produce pollen, which contains the male gametes, and the pistil contains the female reproductive organs, including the ovary, style, and stigma.

The functions of flowers are to attract pollinators, facilitate the transfer of pollen between flowers, and produce seeds for the next generation of plants. Pollinators can be insects, birds, bats, or other animals, and they are attracted to flowers by their colors, fragrance, and nectar. Cross-pollination benefits genetic diversity, which can increase a plant's chances of survival in changing environments. It also allows for the production of hybrid plants with desirable traits.

If samples of nerve cells and bone cells from the same person were run through the same type of microarray, would the results differ? Explain.

Answers

Yes, the results of a microarray analysis of nerve cells and bone cells from the same person are likely to differ.

A microarray is a tool used to analyze the expression levels of thousands of genes simultaneously. It works by comparing the levels of mRNA transcripts in the samples to a reference sample, and determining which genes are up- or down-regulated in the test samples.

Nerve cells and bone cells are two different types of cells that have distinct functions and molecular profiles. They express different sets of genes and have different levels of gene expression. Therefore, when run through the same type of microarray, the mRNA profiles of nerve cells and bone cells are likely to differ significantly.

For example, nerve cells are specialized for transmitting electrical and chemical signals throughout the body, and express genes that support these functions, such as genes encoding ion channels and neurotransmitters. On the other hand, bone cells are specialized for maintaining the structure and strength of bones, and express genes that support these functions, such as genes encoding extracellular matrix proteins and bone remodeling enzymes.

Therefore, even though the samples are from the same person, the mRNA profiles of nerve cells and bone cells are likely to be different due to their distinct functions and gene expression profiles.
Yes, the results from the microarray would differ between the nerve cells and bone cells from the same person because nerve cells and bone cells have different gene expression profiles.

the function of the caecum is to _/_ _ wastes

Answers

The function of the caecum is to absorb salts and electrolytes and lubricate the solid waste that passes into the large intestine.

The cecum's primary roles are to mix its contents with mucus, a lubricant, and to absorb fluids and salts that are left behind after intestine digestion and absorption are complete. A thick mucous membrane makes up the inside wall of the cecum, through which salts and water are absorbed.

In herbivores, the cecum is a food storage area where bacteria may degrade cellulose. The human cecum no longer serves this purpose (see appendix), therefore in people it only serves as a dead-end pouch that is a portion of the big intestine.

The last part of the body to process food is the large intestine, which receives the undigestible components from the small intestine, absorbs water from it, and excretes the waste material known as feces. The rectum and the anus are the organs that the body uses to release feces.

Therefore, the function of the caecum is to lubricate the wastes.
