g. What are two possible changes to environmental factors that could cause the population in area B to experience positive population growth that would allow it to reach the same carrying capacity as the population in area A?

Answer:

Genetic diversity has decreased due to inbreeding due to dwindling population size.

Cheetahs are facing great pressures, such as climate change, destruction of their habitat, and also hunting by humans that have greatly impacted their genetic diversity.

Cheetahs have experienced a very declining rate of their populations due to destruction of their habitat, and also hunting by humans that has resulted in inbreeding in their populations and loss of genetic diversity.

Due to inbreeding, cheetahs have become more exposed to genetic disorders and vulnerable to diseases, and other threats.

Climate change has also posed a great threat to the declining population of cheetahs as it has affected their habitats and food resources. Climate change causes alteration in the temperature and rainfall pattern resulting in low availability of prey and water resources. Therefore, climate change leads to the malnutrition of cheetahs and making them more susceptible to severe disease.

Therefore, cheetahs are facing extinction due to climate change, habitat destruction, and hunting by humans.

Answer:

C. Producers would have less material for making food.

Explanation:

An ecosystem can be defined as the natural living habitats of both living and non-living organisms, in which they interact with one another. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.

A list of the types of organisms in an eco pyramid are;

I. Producers: these are autotrophs or self-feeders such as plants.

II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.

III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.

IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.

In Biology, producers are the living organisms that are capable of manufacturing their own food and as such can provide energy or food for the other living organisms (consumers) in a food chain. Thus, producers are mainly known as the foundation of a food chain and are at the top.

A producer gets energy from the sun and converts it into food. The cells found in producers are capable of converting the energy received directly from the sun into food through a process generally referred to as photosynthesis, converting carbon dioxide from the air, water from the soil, minerals and energy from the sun into organic nutrients.

Hence, if the amount of atmospheric carbon dioxide were decreased, the most direct effect on the ecosystem is that producers would have less material for making food.

Answer:

In some species, cells enter a brief interphase, or interkinesis, before entering meiosis II. Interkinesis lacks an S phase, so chromosomes are not duplicated. The two cells produced in meiosis I go through the events of meiosis II in synchrony. During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes. The mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes. Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis.

Prophase II

If the chromosomes decondensed in telophase I, they condense again. If nuclear envelopes were formed, they fragment into vesicles. The centrosomes that were duplicated during interkinesis move away from each other toward opposite poles, and new spindles are formed.

Prometaphase II

The nuclear envelopes are completely broken down, and the spindle is fully formed. Each sister chromatid forms an individual kinetochore that attaches to microtubules from opposite poles.

Metaphase II

The sister chromatids are maximally condensed and aligned at the equator of the cell.

Anaphase II

The sister chromatids are pulled apart by the kinetochore microtubules and move toward opposite poles. Non-kinetochore microtubules elongate the cell.



Figure 1. The process of chromosome alignment differs between meiosis I and meiosis II. In prometaphase I, microtubules attach to the fused kinetochores of homologous chromosomes, and the homologous chromosomes are arranged at the midpoint of the cell in metaphase I. In anaphase I, the homologous chromosomes are separated. In prometaphase II, microtubules attach to the kinetochores of sister chromatids, and the sister chromatids are arranged at the midpoint of the cells in metaphase II. In anaphase II, the sister chromatids are separated.

Telophase II and Cytokinesis

The chromosomes arrive at opposite poles and begin to decondense. Nuclear envelopes form around the chromosomes. Cytokinesis separates the two cells into four unique haploid cells. At this point, the newly formed nuclei are both haploid. The cells produced are genetically unique because of the random assortment of paternal and maternal homologs and because of the recombining of maternal and paternal segments of chromosomes (with their sets of genes) that occurs during crossover. The entire process of meiosis is outlined in Figure 2.



Figure 2. An animal cell with a diploid number of four (2n = 4) proceeds through the stages of meiosis to form four haploid daughter cells.

Such physiological research will offer a wealth of information that can help in fish survival and management. This include how fish respond to and withstand a variety of environmental factors, as well as how fish bodies and internal processes evolve over time (including smoltification and reproduction).

Fish are more effective at converting feed into body protein than cattle or chickens. It's a lot more economical, which means the fish industries can produce more food with less feed. Since less food and resources are used in the processing of food, the process is therefore less expensive.

RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called siRNA, which form a complex with RISC and degrade specific RNA.

siRNA or small interfering RNA as a part of RISC complex finds and binds to complementary mRNA and it induces the cleavage of mRNA. This causes degradation of that mRNA. This is the way RNA interference prevents translation.

Answer: Homologous structures.

Explanation: The bones labeled A have similar structural arrangement in all the organisms but perform different functions in each organism

The bones labeled as A are known as homologous structures. Therefore, option D is correct.

Homologous organs are those present in several creatures that share a common ancestor and fundamental structure but differ in the roles they perform. The man's forelimbs, a cat's forelimbs, a whale's flippers, and a bat's wings are all examples of homologous organs.

Homologies are characteristics shared by two or more species and derived from their common ancestor. For instance, our common ancestor who lived more than 300 Mya ago left us with both the human five-fingered hand and the lizard's five-toed foot.

The forelimbs of penguins, bats, alligators, and humans are examples of homologous organs. Therefore, option D is correct.

When using images and graphs to express the results of a research, both of them should express the same information to make their interpretation easier. Option A is the one that best models the waves in the four locations.

There are different ways in which a researcher can correctly express the results of an experiment or research. It can be done by using images, tables, graphs, diagrams, etcetera.

Usually, combinations of one or more are used to express the same results in order to make it easier to make interpretations (for instance, tables and charts). In these cases, the same data must be expressed in all of them, so the interpretation is coherent.

In any case, there must always be a reference to what is being shown, so the persons looking at the image, chart, or table, get to know what they are looking at.

For instance, in the exposed example we can see the satellite image of ocean surfaces on Earth at different locations.

To get to understand this image by itself, we need references. These are given below in the sea surface height anomaly gradient.

This gradient explains the change in height from the lowest height -the darkest color that reflects -50 cm-, to the highest height -white expresses 50 cm-.

Letters A, B, C, and D are references to the locations that were considered.

If we want to make a graph with this same information, we need to make a good interpretation of the image and then reflect it in the graph.

In the exposed example, graph A is the one that best reflects the information provided in the image but is not entirely correct.

The graph must express the change in water surface height. This change is expressed in the Y ax of the chart.

Probably the X ax represents normal heights.
