Which of the following groups is difficult to define into species using the Biological Species concept?
A. Vertebrates
B. Asexually reproducing organisms
C. Sexually reproducing organisms
D. Insects

Answer:

I think it will be gene flow, but i'm not for sure

Explanation:

the gene pools can be combined in gene flow, reducing variation between the groups.

The evidence that was put forward by Richard Wrangham to support his hypothesis that intraspecies aggressiveness was common in the last common ancestor of chimpanzees and humans is that chimpanzees conduct raid against individuals in neighboring territories.

Intraspecies aggressiveness is the form of aggressiveness between humans beings and other animals. They're a threat of action that brings about harm.

Richard Wrangham put forward evidence to support his hypothesis that intraspecies aggressiveness was common as he stated that chimpanzees conducted raid against individuals in neighboring territories.

Answer:

Deforestation

1) Scientific evidence shows that deforestation provides the conditions for the spread of a variety of deadly diseases, including the Nipah and Lassa viruses, as well as the parasites that cause malaria and Lyme disease.

Population

2) Increasing population growth causes a large number of people to migrate to urban areas with industrialization.This leads to polluted air, water, noise, and the population in big cities and towns.

Oil Spill

3) Oil spills can be extremely harmful to the environment. When oil spills into the oceans, it can cause big problems. It can harm sea creatures, which can make seafood unsafe to eat.

Soil erosion

4) Soil erosion leads to increased pollution and sedimentation in streams and rivers. Soil gets degraded, the risk of erosion increases, and the sediments sweep into rivers and nearby regions, possibly contaminating nearby ecosystems.

Coral reef degradation

5) Coastal areas become increasingly vulnerable to storms, hurricanes, and cyclones when coral reefs perish. The ocean will be unable to absorb as much CO2 without coral reefs, resulting in more CO2 being released into the atmosphere.

Illegal mining

6) Mining can pollute air and drinking water, harm wildlife and habitat, and permanently scar natural landscapes.

Answer:

diffusion

Explanation:

The concept of diffusion states that molecules like to travel from areas of high concentration to low concentration.

Let's think about an example. Let's say you are having a party at your house and in one room there is 100 people and in the other room connected to it, there is only 10 people. What do you think is going to happen as time passes? Right, people are going to move to the room where there is less people so as to equally disperse themselves across the area. The same thing happens within our body with ions and gases.

Ions can diffuse into or out of cells based off their concentration gradients. If there are too many ions on one side, they will simply move to the other side. There are different types of diffusion. Passive diffusion and facilitated diffusion, but those are for a different conversation.

Agricultural biologicals (or biologics) are beneficial crop production and protection tools that are largely created from living organisms, derived from natural materials, contain them, or use naturally-occurring processes. They complement traditional crop protection tools, using nature’s own defenses to help safeguard plants against pests.

Answer:

C

Explanation:

This must be C

According to the properties of osmosis, the cell will burst. So the correct option is C.

Osmosis is the spontaneous diffusion or flow of water or other solvents over a membrane that is semipermeable and prevents the passage of solutes, or dissolved compounds. The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer.

Previous researchers have conducted less precise examinations of leaky membranes (such as animal bladders) and the transport of water and escape chemicals through them in opposing directions. Thomas Graham, a British chemist, coined the term "osmose," which is still used to refer to the process, in 1854.

A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute. The osmotic pressure, also known as the pressure exerted on the solution, can be raised to a certain level to halt this process.

The Dutch-born chemist Jacobus Henricus van 't Hoff demonstrated in 1886 that osmotic pressure varies with concentration and temperature roughly as it would if the solute were a gas occupying the same volume if the solute is so dilute that its partial vapor pressure above the solution obeys Henry's law (i.e., is proportional to its concentration in the solution.

Therefore the correct option is C.

Answer:

Tomatoes are triggered to turn red by a chemical called ethylene. Ethylene is odorless, tasteless, and invisible to the naked (human) eye.

Explanation:

Answer: As the tomato ripens, its color starts to change from green to yellow and then eventually to red. This is due to the breakdown of chlorophyll, which in turn synthesizes a red carotenoid (another pigment group), lycopene. When ripe, the carotenoid can easily be seen as the dominant color of the tomato, red

Answer:

Amino Acids

Explanation:

During digestion, enzymes in our bodies break the proteins we eat down into amino acids (by hydrolysis). These amino acids are transported around the body by blood. In the bloodstream, condensation reactions build the amino acids up to produce proteins required by the body.

When proteins are broken down, amino acids are formed as the amino acids are joined together by the peptide bonds, and the peptide bond is formed between the amino group and the carboxyl group of the amino acids.

Peptide bonds and proteins are both significant, as the peptide bonds are formed by the amino acids, and the amino acids unite to make the protein. The breakdown of proteins in the body is a continuous process, as in this process new proteins are formed and the protein structure depends upon the amino acid composition.

Hence, when proteins are broken down, amino acids are formed as the amino acids are joined together by the peptide bonds, and the peptide bond is formed between the amino group and the carboxyl group of the amino acids.

Answer:

In biology, osmosis is defined as the net movement of water molecules through a semipermeable membrane (e.g. cell membrane) from an area of higher to an area of lower water potential. Other definitions of osmosis are as follows:

The process of a solvent diffusing through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration

The tendency of water to flow from a hypotonic solution (low concentration of dissolved substances) to hypertonic solution (higher concentration of dissolved substances) across a semipermeable membrane

In chemistry, osmosis is defined similarly. It is the passage of a pure solvent from a solution of lesser to one of greater concentration of solutes when the two solutions are separated by a membrane that selectively prevents the passage of solute molecules while allows the solvent molecules to pass through.

Explanation:

Preganglionic neurons of the autonomic nervous system are located in the lateral gray horns of the spinal cord.

The function of the preganglionic neurons is to activate nicotinic receptors on the postganglionic neurons through the utilization of a neurotransmitter known as acetylcholine.

During the process of transmissions in the autonomic nervous system, the preganglionic neurons significantly liberated acetylcholine at its ganglion. This is the first stage at which transmission is triggered with respect to the response.

The preganglionic neurons of the autonomic sympathetic nervous system are normally found within the region of the spinal cord especially, in the lateral gray horns with its axon subsisting at the ventral roots.

Therefore, preganglionic neurons of the autonomic nervous system are located in the lateral gray horns of the spinal cord.

Explanation: Microscopes often use a mirror to direct available light to the specimen platform, so if you don't have enough light it will be difficult to view your specimen and can cause eye strain.

Microscopes may malfunction if stored or used in a location exposed to direct sunlight. Also, direct sunlight may harm the observer's eye if it enters a microscope through the reflector.

For optical microscopes:

Light from outside is sent to the reflective mirror to illuminate the sample. Direct sunlight must be avoided. ... This inexpensive and readily available lamp, also called an incandescent lamp, is widely used in optical microscopes.
