Descriptive investigations involve collecting data about a system, but not making what?
Answer:
The correct answer to the following question will be "Tests or experiments".
Explanation:
Descriptive investigations attempt to build assumptions from either the predictions of the phenomena, even as experimentally investigated were mostly designed to allow the research scientist to make comparisons under various situations with both the control behavior.There are indeed enough that-called comparison investigations, that also gather information analyze varying environments but don't even include the regulate location.So that the above would be the appropriate answer.

The organism shown is a free-living one that is anchored to the bottom of ponds and streams during one stage of its life cycle. What is the common name of the group to which this organism belongs? bryozoans rotifers cnidarians mollusks there is a picture in the file below.
Answer:
cnidarians
Explanation:
bryozoan - "Bryozoa are a phylum of aquatic invertebrate animals. Typically about 0.5 millimetres long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia." -Wikipedia
rotifers - "The rotifers, commonly called wheel animals or wheel animalcules, make up a phylum of microscopic and near-microscopic pseudocoelomate animals." -Wikipedia
cnidarians - "Cnidaria is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments: they are predominantly marine. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick.
" -Wikipedia
mollusks - "Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda. The members are known as molluscs or mollusks. Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high." -Wikipedia
(The Wikipedia entries are for describing.)

Why is water pollution a concern if water is continuously cycled through Earth’s systems?
Water pollution is still a concern, even though its cycled through the Earth's system continuously, for many reasons. Firstly, people still continue to dump toxic chemicals, and plastic/ garbage into the water. Plastic doesn't decompose, it continues to sit and pollute the ocean unless it is cleaned up. Then there are also the chemicals. Some of these chemicals don't dissipate, or clear out for many years. There is also oil that has been spilt into the ocean. Even though it was many years ago, it still lingers in the ocean, and is very difficult to clean up. Secondly, there are bacteria and algae that lives in the water, which makes it very harmful for us if not cleaned out. The Earth's system is unable to keep these organisms out of the water. Thirdly, there is constantly water, even though water goes through the cycle, there is still unfiltered polluted water that stays, and then pollutes the filtered water.

How might biodiversity be important to an ecosystem’s health and stability?
A. One of the late symptoms of MN is excessive edema, or build up of fluid within the interstitial space of tissue. Explain how loss of circulating blood protein (hypoalbuminemia) would cause edema with respect to hydrostatic and colloid osmotic pressure within capillary beds throughout the body.
Answer:
Albumin is a protein that attracts water in the compartment where it is found, that is why when circulating within the blood vessels the blood volume is maintained by this protein, so that the liquid or fluid that makes up the blood volume is retained within the capillaries due to hydrostatic forces and because the albumin protein is hydrophilic.
The albumin is decreasing, that is, in deficit or hypoalbulinemia, less water reaches the blood compartment, therefore the blood pressure or pressure will drop, the blood volume will decrease but not due to loss of it as in hemorrhages, but due to diffusion to other compartments. VASCULAR through the processes of OSMOSIS, in simple words, when this protein descends, water filters from the blood vessels to extravascular compartments, this phenomenon clinically manifests itself as EDEMA.
Explanation:
Hypoalbulinemia also occurs in severe nutritional disorders where ovalbumine is not consumed through the egg, since the person's diet is severely lacking, generating massive edema in the abdominal area or abdominal distension.
The effect that the plasma liquid has in spreading to extravascular spaces is called OSMOSIS, which draws water from the external environment by the oncotic pressure generated by other proteins.
The oncotic pressure is the pressure that is generated when the water diffuses from one compartment to another by attraction of a protein, it happens both with albumin and with other proteins of the organism that are characterized by being hydrophilic or attracting water.
Hypoalbulinemia destroys severe cardiac symptoms due to the high demand that an increase in edema and difficulty of venous return entail along with the fall in blood pressure.

A forest fire destroys an area. A small population of trees and a large population of birds are both affected. Which type of
limiting factor causes this?
Odensity dependent
Odensity independent
O population dependent
population independent
Answer:
density independent
Explanation:
In Ecology, a limiting factor refers to an environmental condition that hinders the growth and distribution of organisms in an ECOSYSTEM. A limiting factor hinders or hampers the productivity of an organism in its habitat.
There are two major types of limiting factors that affect organisms in their ecosystem viz: density dependent and density independent limiting factors. Density independent factor limits the size of a population independently of how dense the ecosystem's population is. This means that density independent factor affects a population irrespective of its size. Example of density independent factor are natural disasters e.g earthquake, hurricane, forest fire as mentioned in the question.
In this question, both populations of trees and birds are affected irrespective of the size of the ecosystem's population.
Which would most likely lead to reduced bird populations?
O A. Lack of land development
OB. Overplanting an area
O C. Introduction of non-native species
O D. Increased insect populations
Answer:
Introduction of non-native species
Explanation:
That would most likely lead to reduced bird populations is O C. Introduction of non-native species.Non-native predators may also prey on native birds and their eggs, leading to population declines.
What are non-native species?Non-native species, also known as alien, exotic, or introduced species, are organisms that have been introduced into a geographic area where they did not occur naturally, either intentionally or unintentionally, by humans.
C. Introduction of non-native species is most likely to lead to reduced bird populations.
Non-native species may compete with native species for resources such as food, nesting sites, and breeding territories, and may also introduce new diseases and parasites that the native species may not be able to cope with.
Non-native predators may also prey on native birds and their eggs, leading to population declines.

In the Hardy-Weinberg equation shown below, p is the frequency of the
dominant allele, and gis the recessive allele.
p'+ 2pq + 9 = 1
What does p2 represent in the equation?
A. The frequency of the heterozygous dominant genotype
B. The frequency of the homozygous dominant genotype
C. The frequency of the homozygous recessive genotype
D. The frequency of the heterozygous recessive genotype
In the Hardy-Weinberg equation shown below, p is the frequency of the
dominant allele, and is the recessive allele. p² in the equation represents the frequency of the homozygous dominant genotype.
Dominant allele: What is it?Usually, a dominant allele codes for a protein that functions. Because only one copy of the allele is required to produce enough enzyme to fully provide a cell with a specific product, the allele is dominant.
Describe genotype.An organism's phenotype, or observable traits, are derived from its genotype, or the chemical makeup of its DNA. All the nucleic acids in a DNA molecule that code for a specific trait are collectively known as a genotype.
