which best describes an effect of habitat fragmentation

Food that reaches the large intestine is transformed from liquid chyme residue into semisolid feces through water absorption. Composed of various undigested and unabsorbed substances and aided by intestinal bacteria, the final waste is stored in the rectum until defecation.

When food reaches the large intestine, it has already had most of its nutrients absorbed in the small intestine. The large intestine's main role is the absorption of the remaining water from the liquid chyme residue, a process that converts this residue into semisolid feces or stool. The colon, which is the main part of the large intestine, assimilates any leftover salts and water. Additionally, the large intestine hosts a diverse microbiota that aids in further digestion. The semi-solid waste is then moved through the colon by peristaltic movements and stored in the rectum until eliminated through the anus.

Final answer:

The direction of diffusion is primarily determined by the concentration gradient, with substances moving from areas of high concentration to areas of low concentration, as described by Fick's First Law.

Explanation:

The rule that governs the direction of diffusion is centered around the concept of moving from an area of high concentration to an area of low concentration. This natural process is succinctly summarized by Fick's First Law, which states that the flux of molecules, J, through a surface is directly proportional to the concentration gradient across that surface. That is, molecules will diffuse down the concentration gradient. The rate of diffusion is influenced by the concentration difference and the diffusion constant D, with the net rate being highest when the concentration gradient is steepest.

Diffusion is crucial for the transport of nutrients and wastes in biological systems. In smaller or single-celled organisms, diffusion serves as the main mechanism for these exchanges, while in larger, more complex organisms, circulatory systems have evolved to facilitate transport over greater distances quickly, supplementing the process of diffusion.

Answer:

The principal difference is the amount of organic content in the soil

Explanation:

In warm places of the world there is a lot of life, there we can find big forests where are living thousands of animals and plants; when this organisms die they rest on the ground and start a descomposition until become part of the soil. This kind of soil is very dark, almost black, is humid and very rich in nutrients and minerals.

The Antartic weather doesn't allow a lot of life to be there and for that reason its soil has a poor amount of organic content. Besides, the climate there is considered dry and its soils have not enough amount of water.

There are differences related with the rocks under the soil, but actually we have all kind of rocks all over the world, so it is not the most important difference.

The central nervous system (CNS) of the body.

It belong in Eubacteria

Eubacteria are unicellular, heterotrophic prokaryotic cells and are ubiquitous (can be found everywhere). The cells of Eubacteria lack a true nucleus and some organelles such as mitochondrions or chloroplasts. They possess a rigid cell wall that is composed of peptidoglycan and a cell membrane that is made up of a phospholipid bilayer. Eubacteria usually reproduce asexually through the process of binary fission.

Active transport in the phloem involves energy expenditure to concentrate sugars in the sieve tubes, creating a solute potential that attracts water osmotically. This increases pressure, driving bulk flow from sugar sources to sinks. Osmosis, being a passive process, relies on the solute concentrations established by active transport.

The role of active transport in the phloem involves the movement of sugars into the sieve-tube elements, a process that requires energy, usually in the form of ATP. This energy expenditure is crucial for phloem loading, where sugars are concentrated against a gradient from areas of lower concentration to higher concentration within the sieve tubes. In contrast, osmosis is a passive process where water moves across a semi-permeable membrane from an area of higher water concentration (lower solute concentration) to an area of lower water concentration (higher solute concentration) due to a solute potential created by the actively transported sugars.

Active transport creates a high concentration of solutes (sugars) which then osmotically attracts water from the xylem into the phloem, increasing the pressure within the phloem tubes. This increased pressure drives the bulk flow of the phloem sap from the source (where sugars are synthesized) to the sink (where sugars are utilized or stored). While osmosis does not require energy, the bulk flow in the phloem reliant upon osmosis indirectly depends on the energy expended for active transport during phloem loading and unloading.

The +1 ion of a lithium atom is represented by 3 protons, 3 neutrons, and 2 electrons, Ernest Rutherford proposed the Planetary model of the atom, and in Thomson's Plum Pudding Model, the plums symbolize electrons.

Explanation:

Lithium Ion and Atomic Models

The set of particles that represents a +1 ion of a lithium atom, which normally has 3 protons, 3 neutrons, and 3 electrons, would be the one that has a missing electron. Therefore, the correct answer is B) 3 protons, 3 neutrons, and 2 electrons. This set of particles has one less electron than protons, giving it a +1 charge.

The scientist who stated that electrons travel around the nucleus like planets around the sun, which is referred to as the Planetary model, was Ernest Rutherford.

In Thomson's "Plum Pudding Model" of the atom, the "plums" represent electrons.

Humans absolutely depend on photosynthesis to survive as it is responsible for producing the oxygen we breathe and the food we consume. The energy in the food we eat originates from photosynthesis, which captures solar energy to create carbohydrates in plants. Photosynthesis also removes carbon dioxide from the atmosphere, which is particularly important as we burn fossil fuels.

Absolutely, humans depend on photosynthesis for survival. Photosynthesis is a process primarily carried out by plants, algae, and certain bacteria, which harness the sun's energy to convert carbon dioxide and water into glucose, a sugar that serves as food for many organisms, and release oxygen as a byproduct. This oxygen is what humans and other animals breathe. Moreover, the energy contained in food that all animals, including humans, consume can be traced back to photosynthesis. The process, therefore, supports both the oxygen we need to breathe and the food we need to eat.

Consider the energy journey—from the sun's energy to the carbohydrates in plants created through photosynthesis, then to the animals that eat those plants, and finally to the predators that eat those herbivores. In each step, the energy transferred originates from photosynthesis, and it illustrates the fundamental role this process plays in sustaining life on Earth. Through photosynthesis, organisms capture solar radiation and store it as high-energy electrons within carbon-carbon bonds of carbohydrates.

Moreover, photosynthesis not only fuels the earth's ecosystems but also cleanses our atmosphere by absorbing carbon dioxide, including that which we produce from burning fossil fuels. Thus, we see that our survival and way of life are intimately linked to photosynthesis, making it one of the most crucial biological processes.

The right option is; D) Light-dependent; light-independent

Light-dependent and light-independent reactions are both parts of photosynthesis.  

Photosynthesis is a chemical process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide, water, and light energy in chloroplasts. During the process of photosynthesis both light dependent reaction and light-independent (dark) reaction occur in the chloroplast. The light reactions depends on light to generate organic energy molecules (ATP and NADPH) which are stimulated by chlorophyll (green colored pigment) while the dark reactions is light independent. It takes place in the stroma and ATP energy is used, while the electrons that are needed to fix carbon dioxide into carbohydrates is provided by NADPH.

The cross between a homozoygous recessive dwarf pea plant (tt) and a heterozygous tall pea plant (Tt) results in a 1:1 phenotypic ratio of the offspring, meaning half will be tall (Tt) and half will be dwarf (tt).
