Answer: A chromosome is a long DNA molecule with part or all of the genetic material of an organism. The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not.

Explanation:

Answer:The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.

Answer:

suspended particle pollution

Explanation:

Volcanic eruptions and landslides cause excess soil and rocks fall into waterways.

The type of pollution may result from a volcanic eruption or landslide is suspended particle pollution, i.e., option C.

Particulate matter in suspended form is microscopic solid or liquid matter suspended in the Earth's atmosphere.

It is also known as particulate matter or particulates. Particulate matter is the accumulation of all solid and liquid particles suspended in air, many of which are dangerous.

This is the type of pollution may result from a volcanic eruption or landslide is suspended particle pollution.

Thus, the correct option is C.

Explanation:

Explanation:

Keystone species are animals that help manage other animal species by controlling population numbers and biodiversity within an ecosystem. The impacts of keystone species are usually greater than their numbers. 

owls can be a great benefit to places where rodent populations are high. Dense urban areas often suffer from an abundance of rats and mice spreading disease, and rural agricultural communities have their crops consumed and soil eroded from burrowing voles and field mice. Without owls, and other top predators, rodent populations could explode and exacerbate the effects they produce.

Answer:

the owl is a keystone species, as many other birds. and it gives them the nutrients they need when they eat the bird and it mangeges the population of the other species:)

Answer:

Essay about the rise of global temperatures over the past century.

Explanation:

The rise of global temperatures over the past century is the major issue which occurs due to human activities. The use of fossil fuels in vehicles releases huge amount of carbondioxide gas in the air while burning. Carbondioxide gas is a green house gas which blocks the reflected solar radiation to go away in the space. These solar radiation remains in the surface which increases the surface temperature of the earth. This rising in the surface temperature is responsible for the melting of glaciers that leads to the rise of sea level which is a threat for coastal regions. This melting of glaciers also causes floods in the regions so that's why the it is a major issue.

The statement which is supported by the information in the bar graph is that: B. trade between nations steadily increased between 1988 and 2013.

A bar graph can be defined as a type of chart that is used to graphically represent data (information), especially by using rectangular bars or vertical columns.

Based on this bar graph titled Global Trade (Percent of GDP), we can infer and logically conclude that trade between nations increased steadily between 1988 and 2013, which was from over 40 percent (40%) to almost 60 percent (60%).

Answer:

1. Homeostasis.

2. Osmoregulation.

3. Thermoregulation.

4. Endotherm.

5. Ectotherm.

6. Excretion.

Explanation:

1. The level of glucose in a person's blood stays relatively constant even after he or she eats a sweet dessert. This is an example of homeostasis, which is the maintenance of relatively constant internal conditions despite fluctuations in the external environment. Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.

2. The maintenance of internal water and solute concentrations within a narrow range is called: osmoregulation. Normovolemic describes the situation in which a living organism maintains a normal volume or amount of blood in the body.

3. The maintenance of internal temperature within a narrow range is called: thermoregulation. Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).

4. An endotherm, such as a pigeon, is an organism that gains body heat primarily from its own metabolism. It is also referred to as homotherm and it involves maintaining a constant body temperature.

5. An ectotherm, such as a salamander, is an organism that gains body heat primarily by absorbing it from the environment. Thus, an ectotherm have limited abilities with respect to regulating its body temperature.

6. The disposal of nitrogen-containing wastes, as through urination, is called: excretion. Glomerular capsule is also referred to as Bowman's capsule and it can be defined as a cuplike sac (structure) with a double wall, which makes up the tubular part of a nephron within the kidney of mammals. It is saddled with the responsibility of first filtering blood (ultrafiltration) under pressure to generate urine in the mammalian kidney.

Hello. You did not present the cladogram to which the question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.

A cladogram is the representation of the evolutionary relationships between living beings, showing ancestry and the genetic relationship between them. The cladogram is represented by lines and dots. The lines represent the evolutionary time and the dot between them represents the ancestor of a new species. In this case, to answer your first question, we can consider that the most recent ancestor of all species is the ancestor of the central line. However, the most recent ancestor, shared only by gymnosperms and angiosperms, is the one that is in the dot closest to the lines that represent gymnosperms and angiosperms.

Transcription is the cellular process of RNA synthesis by decoding the information contained in a DNA fragment  

Explanation:

Transcription is the process by which the genetic information contained in a fragment of DNA called 'gene' is used as a template to synthesize an RNA molecule, usually, a messenger RNA (mRNA), which is subsequently used to synthesize a protein by the process of translation. In eukaryotic organisms, transcription involves a DNA template strand, which contains both non-coding (i.e., promoter, introns) and conding (i.e, exons) regions, and an RNA polymerase that adds nucleotides to the growing RNA strand using as a template a DNA strand. Both in prokaryotes and eukaryotes, transcription occurs in three basic steps: 1-initiation, where DNA strands separate, 2- elongation, where the RNA polymerase moves on the DNA sequence to synthesize an RNA molecule, and 3-termination, where transcription terminates depending on the sequence in the RNA (eukaryotic transcription has an additional step known as RNA processing).

Uranus and Jupiter both have rings, both have moons, but they are mostly gas planets, and both have some methane. I think id.k if that helped

Uranus is similar to Jupiter in that it has methane in its atmosphere. Therefore, the correct option is D.

Both Jupiter and Uranus are planets in our solar system. Jupiter, the largest planet in our solar system, is located five planets from the Sun. Uranus, the third largest planet in our solar system, is located at a distance of seven planets from the Sun.

Both planets are gas giants, with atmospheres composed mostly of hydrogen and helium. Their upper atmospheres also include methane gas, which gives them a blue-green colour. However, there are many differences between Uranus and Jupiter. Although they are much less noticeable than Saturn's rings, Uranus has a system of rings and at least 27 moons. Compared to Jupiter, Uranus is smaller and has less mass.

Therefore, the correct option is D.
