An ecological footprint A) is a means of determining increases in populations that lived in the past. B) is a means of understanding resource availability and usage. C) measures dispersion and adaptability. D) will estimate population movements.
Answer: An ecological footprint is a means of understanding resource availability and usage. The correct option is B.
Explanation:
The ecological footprint is a method which is used to measure the rate as which humans use natural resources in their environment and generate waste from them compared with how fast nature can absorb these wastes and generate the used resources again. The productive areas which are measured through this means are:
--> cropland,
--> grazing land,
--> fishing grounds,
--> built-up land,
--> forest area, and carbon demand on land.
The importance of ecological footprint to the environment should no the over emphasizes. When properly observed, different environmental pollution would be dealt with. Generally, there would be:
--> decreased desertification,
--> decreased global warming
--> availability of fresh unpolluted air and
--> decreased carbon emissions.
Describe one property of water, and explain how the structure of water is responsible for this property. WILL MARK BRAINLIEST!!
Answer:
Water has cohesive and adhesive properties.
Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid's surface to resist rupture when placed under tension or stress.

Colleen made a list comparing the differences between the physical structures that provide support to both plants and animals, but she made a mistake. Read the table and then choose the statement that explains why the list is incorrect. (2 points)
Structure Description of Function
Stem Supports the plant and holds the leaves toward the ground
Skeleton Protects the internal organs and helps with movement
Group of answer choices
The role of the skeleton is to prevent movement, not help it.
The skeleton is unable to protect internal organs.
The stem holds the leaves up toward the sunlight, not towards the ground.
The stem only transports water throughout the plant, not supports it.
Answer:
The stem holds the leaves up toward The sunlight
Explanation:
leaves need sunlight to photosythesize

Why can't a hair shaft be used to collect an individual's DNA
Answer:
A hair w/out the follicle and its nuclear DNA, or genetic material in its nucleus, cannot provide individual evidence. Physical examination of the hair can only yield class evidence.
Explanation:
Answer: Hope this helps!
Explanation:
When performing a hair DNA test for the purpose of paternity, it is a must to have a complete hair sample – with hair shaft and hair follicle. On the other hand, if the purpose of hair DNA testing is for forensic use, a cut hair sample even with no follicle can still be of use. However, a complex procedure has to be made.
Which of the following biomolecules is responsible for genetic information? *
A. Carbohydrates
B. Lipids
C. Nucleic Acids/Nucleotides
D. Proteins
Answer:
C
Explanation:
Hi, the answer is C, because nucleotides and acids form DNA and RNA, which store genetic information. Hope this helps!
Answer:
C. Nucleic Acids/Nucleotides
Explanation:
Among biomolecules, nucleic acids, namely DNA and RNA, have the unique function of storing an organism's genetic code—the sequence of nucleotides that determines the amino acid sequence of proteins, which are of critical importance to life on Earth.
How can extinctions and expansions occur in the same habitat? Explain your answer.
When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Habitat loss is perhaps the greatest threat to organisms and biodiversity.Extinction happens when environmental factors or evolutionary problems cause a species to die out. The disappearance of species from Earth is ongoing, and rates have varied over time.
Extinctions are associated with biodiversity changes, thereby affecting species expansion.
What is extinction?Extinction refers to the disappearance of a given taxonomic group (e.g. species-level extinction).
This process of disappearance (extinction) modifies the trophic relationships in the ecosystem.The modification may lead to the expansion of a given species (e.g., prey in the case of predator extinction).In conclusion, extinctions are associated with biodiversity changes, thereby affecting species expansion.

The creation of genetically identical offspring by a single parent, without the participation of sperm and egg, is called The creation of genetically identical offspring by a single parent, without the participation of sperm and egg, is called spontaneous generation. asexual reproduction. regeneration. sexual reproduction.
Answer:
Asexual reproduction.
Explanation:
The generation of genetically identical offspring from a single parent, without the fusion of sperm and egg, is called asexual reproduction. Asexual reproduction occurs when there is only one parent from which organism is produced. Budding, binary fission and fragmentation are the different types of asexual reproduction that involves only one parent and no fusion of sperm and egg cells.
What are the oceanic features and functions
Answer:
Explanation:
What are oceanic features?
Features of the ocean include the continental shelf, slope, and rise. ... Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.\
The air we breathe: The ocean produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth's surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.

Answer:
Option A, Fixed quota models are risky because slight miscalculations can result in fish population extinction
Explanation:
Some of the major drawbacks of modelling fishing are as follows –
a) The fixed quota model is very risky as a miniscule change in attributes can result into extinction of fish.
b) On the other hand fixed effort harvesting can decrease the risk of fish population extinction

Explanation:
A lack of CO2 in the flask would have caused reduced O2 production. If O2 , ATP, and NADPH are the by-products of the light-dependent phase of photosynthesis, how does a lack of CO2 cause reduced O2 production
Answer:
Carbondioxide is a reactant of photosynthesis.
Explanation:
Carbondioxide is a reactant of the process of photosynthesis and the product of photosynthesis is oxygen, if there is no or less carbondioxide the rate of photosynthesis decreases which leads to the lower production of oxygen. The rate of photosynthesis affected by the reactants available to it. If Carbondioxide is available in large amount more photosynthesis occurs that leads to more production of glucose as well as oxygen. So we can conclude that lack of Carbondioxide results in lower production of oxygen in the process of photosynthesis.

Venules are the smallest venous vessels (option B)
What are venous vessels?Venous vessels refer to the blood vessels for transporting blood from the tissues back, to the heart. They work in contrast to arteries, which carry oxygenated blood from the heart to the tissues.
Compared to arteries, venous vessels usually have dimensions and thinner walls. The reason, behind this is that they don't require pressure to transport blood. Additionally venous vessels possess valves that aid in preventing the flow of blood.
Base on the information above, we can infer that Venules are the smallest venous vessels (option B)

People traveling to an island accidentally introduced mice into an ecosystem that previously had no mice. The population of mice quickly grew out of control. It started harming populations of native plants and birds. Scientists offered two solutions. One was to introduce cats to the island. The cats could hunt and eat the mice. The other suggestion was to introduce a disease that could infect the mice and reduce their population.
Answer:
Cat.
Explanation:
Introduction of cat can control the population of mice on the island more effectively as compared to the introduction of disease because the introduction of disease can cause damage to other population of that environment that adversely affected the ecosystem. Cat feeds on mice that act as a controlling agent in this ecosystem that will leads to decrease as well as controls the population from increasing in order to cause damage to the environment.
