Answer: 200 seeds will be yellow.

Explanation: In this crossing, one parent will produce half of its gametes carrying allele Y and the other half carrying allele y. The other parent will have gametes with allele Y. After fecundation, the offspring could phenotype YY or phenotype Yy.

In genetics, Y is related to the dominant allele and y to the recessive one. In this case, having the Y dominant allele determine the color yellow. Therefore, as all of the offspring has the dominant allele Y for yellow, all of the seeds will be yellow, i.e., 200 seeds will be yellow.

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.

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.

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.

Answer: B body systems are made up of organs

Answer:

The correct answer to the following question will be "Tests or experiments".

Explanation:

So that the above would be the appropriate answer.

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.

The given question is incomplete as it does not have the options which are:

A. commensalism

B. mutualism

C. parasitism

D. predator-prey

Answer:

B. mutualism

Explanation:

The species in the ecosystem interact with each other in many ways and one such type of interaction in which both the species are equally benefitted is known as the mutualism.

When one species provides benefit to second species whereas the second species provides benefit to the first species in a way that the evolution has transformed the relationship into an inseparable or highly dependent relationship.

In the given question, the shrimp provide a safe habitat to the goby fish whereas goby fish protect the shrimps from the predators. Since both the species are benefitting each other therefore the species form a symbiotic relationship.

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.

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.

Answer:

Water is the basis of all living processes. More than half of the human body is made up of water, while human cells are more than 70 percent water. Thus, most land animals need a supply of fresh water to survive. However, when examining the stores of water on earth, 97.5 percent of it is non-potable salt water. Of the remaining water, 99 percent is locked underground as water or as ice. Thus, less than 1 percent of fresh water is easily accessible from lakes and rivers. Many living things, such as plants, animals, and fungi, are dependent on the small amount of fresh surface water supply, a lack of which can have massive effects on ecosystem dynamics. Humans, of course, have developed technologies to increase water availability, such as digging wells to harvest groundwater, storing rainwater, and using desalination to obtain drinkable water from the ocean. Although this pursuit of drinkable water has been ongoing throughout human history, the supply of fresh water is still a major issue in modern times.

Carbon, the second most abundant element in living organisms, is present in all organic molecules. Its role in the structure of macromolecules is of primary importance to living organisms. Carbon compounds contain especially- high forms of energy, which humans use as fuel. Since the 1800s (the beginning of the Industrial Revolution), the number of countries using massive amounts of fossil fuels increased, which raised the levels of carbon dioxide in the atmosphere. This increase in carbon dioxide has been associated with climate change and other disturbances of the earth’s ecosystems. It is a major environmental concern worldwide.

The carbon cycle is most easily studied as two interconnected sub-cycles: one dealing with rapid carbon exchange among living organisms and the other dealing with the long-term cycling of carbon through geologic processes.

Getting nitrogen into the living world is difficult. Plants and phytoplankton are not equipped to incorporate nitrogen from the atmosphere (which exists as tightly-bonded, triple-covalent N2), even though this molecule comprises approximately 78 percent of the atmosphere. Nitrogen enters the living world via free-living and symbiotic bacteria, which incorporate nitrogen into their macromolecules through nitrogen fixation (conversion of N2). Cyanobacteria live in most aquatic ecosystems where sunlight is present; they play a key role in nitrogen fixation. Cyanobacteria are able to use inorganic sources of nitrogen to “fix” nitrogen. Rhizobium bacteria live symbiotically in the root nodules of legumes (such as peas, beans, and peanuts), providing them with the organic nitrogen they need. Free-living bacteria, such as Azotobacter, are also important nitrogen fixers.

Phosphorus is an essential nutrient for living processes. It is a major component of nucleic acid, both DNA and RNA; of phospholipids, the major component of cell membranes; and, as calcium phosphate, makes up the supportive components of our bones. Phosphorus is often the limiting nutrient (necessary for growth) in aquatic ecosystems.

Phosphorus occurs in nature as the phosphate ion (PO43−). In addition to phosphate runoff as a result of human activity, natural surface runoff occurs when it is leached from phosphate-containing rock by weathering, thus sending phosphates into rivers, lakes, and the ocean. This rock has its origins in the ocean. Phosphate-containing ocean sediments form primarily from the bodies of ocean organisms and from their excretions. However, in remote regions, volcanic ash, aerosols, and mineral dust may also be significant phosphate sources. This sediment then is moved to land over geologic time by the uplifting of areas of the earth’s surface.

Explanation:

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.
