Answer:

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.

Sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.

Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Explanation:

Answer:

1. Igneous rocks form when magma molten rocks cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.

2. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

Bacteria

Explanation:

humans, plants, fungi and bacteria are a type of organism

Answer:

When you inhale, muscles increase the size of your thoracic (chest) cavity and expand your lungs. This increases their volume, so pressure inside the lungs decreases. As a result, outside air rushes into the lungs. That's because a gas always flows from an area of higher to lower pressure.

Answer:

The air pressure in your lungs has to be less than the air outside your lungs, to get your lungs to inflate. This is because air moves from high pressure areas to low pressure areas. During bad weather and at high altitudes the air pressure is lower, making it harder for us to breathe.

A triallelic gene determines a person's blood type according to the allele combination. This gene expresses complete dominance and codominance. Option B) Jethro is right and is a winner-winner (chicken dinner).

The ABO blood type is determined by a triallelic gene I. Depending on the allelic interaction, this gene can express complete dominance or co-dominance. Let us see,

Alleles

→ IA and IB are codominant, meaning that when they are together in the same genotype, both of them are expressed.

→ IA and IB express complete dominance over i, meaning that the dominant IA and IB alelles hide the expression of the recessive allele i in heterozygous individuals.

Genotypes          Phenotype

IAIA, IAi         ⇒   Blood type A

IBIB, IBi         ⇒   Blood type B

The number of possible connections among the neurons of the brain is about 500 trillion (B).

Neurons are specialized cells that process and transmit information in the brain. Each neuron is connected to other neurons through synapses, which are the sites of communication between neurons. The number of possible connections between neurons in the brain is incredibly large.

According to estimates, the human brain has about 100 billion neurons, and each neuron can form connections with up to 10,000 other neurons. This means that the total number of possible connections in the brain is about 1 quadrillion (10^15).

However, not all possible connections are formed in the brain, and the actual number of connections is estimated to be around 150 trillion (10^14). Therefore, the correct answer to the question is an option (B) about 500 trillion.

The geologic map above depicts four rock units labeled A through D in order from oldest to youngest, in an area with low topographic relief.

Based on the information provided, the structure represented on the map is likely an anticline. An anticline is a fold in rock layers that arches upward, with the oldest rock layers at the core of the fold. The geologic map above depicts four rock units labeled A through D in order from oldest to youngest, in an area with low topographic relief. This is consistent with the map, which shows the oldest rock unit (A) at the center of the fold, surrounded by younger units (B, C, and D) on either side.
A basin, on the other hand, is a depression in the Earth's surface that is often filled with sediment. A dome is a type of fold in which rock layers arch upward but with the youngest rocks at the center, the opposite of an anticline. A syncline is another type of fold in which rock layers fold downward, with the youngest layers at the core of the fold. Given that the map shows the oldest rock unit at the center of the fold, and younger rocks on either side, an anticline is the most likely structure represented.

The most important of cellular respiration is TRANSFORMING the energy in glucose and related molecules into a chemical form (ATP) that cells can use for work. This process occurs in aerobic cells.

Cellular respiration is a series of metabolic reactions by which aerobic cells use oxygen and the energy stored in the chemical bonds of foods (e.g., glucose) to produce ATP and carbon dioxide.

Cellular respiration has three main stages: glycolysis, the Krebs cycle (i.e., the acid citric cycle) and oxidative phosphorylation.

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

The part of the bigclaw snapping shrimp's claw that moves is called the dactyl. The dactyl is the movable finger-like part of the claw that snaps shut.


The bigclaw snapping shrimp, as shown in Figure 1, has a unique characteristic of having one large claw that snaps shut quickly. This snapping action is made possible by the movement of a specific part of the claw called the dactyl. The dactyl is the finger-like structure that is capable of closing the claw with remarkable speed. When the shrimp wants to capture prey or defend itself, it flexes the muscle associated with the dactyl, causing it to rapidly close the claw. This rapid snapping motion generates a powerful force, enabling the shrimp to stun or immobilize its prey.

In summary, the bigclaw snapping shrimp has a specialized part of its claw called the dactyl, which allows it to snap the claw shut quickly. This snapping action is crucial for capturing prey and self-defense purposes.

Under normal conditions, most nutrients are reabsorbed in the proximal convoluted tubule (PCT) of the nephron.

The PCT is the first segment of the renal tubule, located immediately after the glomerulus. It has a highly convoluted structure, providing a large surface area for reabsorption. The PCT plays a crucial role in the reabsorption of important substances, including nutrients, back into the bloodstream. As filtered blood flows through the glomerulus, essential molecules like glucose, amino acids, vitamins, and ions are freely filtered into the renal tubule.

However, these valuable substances need to be reabsorbed to maintain their proper levels in the body. In the PCT, the epithelial cells lining the tubule actively transport and reabsorb the majority of filtered nutrients and ions. This reabsorption occurs through various transporters on the apical and basolateral membranes of the tubular cells. The nutrients are then transported across the tubular epithelium and enter the peritubular capillaries to be returned to the bloodstream.

Explanation:

A raindrop of almost pure water lands on a microbe. Mechanosensitive channels, activated by osmotic pressure, are used by microbes to reduce their internal solute concentration by letting solutes out.

In microorganisms, Mechanosensitive channels are very crucial as they play a significant role in different cellular functions. These channels are triggered by the difference in osmotic pressure in cells.

Different cellular functions performed by them include fluid homeostasis, transfer or expression of genetic information, cell adhesion, cell division, and migration.

Moreover, these channels also make a response to membrane tension by changing their conformation.

As these channels serve as a certain passage for different ions therefore they also activate various cells such as cochlear hair cells, sensory cells, and sensory neurons as a result of force applied to proteins.

2. Photosynthesis and cellular respiration moving carbon through the atmosphere: Photosynthesis removes carbon dioxide from the atmosphere as plants convert it into glucose and release oxygen. Cellular respiration releases carbon dioxide back into the atmosphere as organisms break down glucose for energy.

3. How organisms store carbon: Organisms store carbon in their tissues as organic compounds like carbohydrates, proteins, and fats, created through photosynthesis or consumption of other organisms. Some carbon is stored in soil as organic matter, while some may become fossilized over time in the form of fossil fuels.
