Answer:
Food webs are more complex than food chains, yet equally as useful in understanding the processes of ecological communities. A food web shows the flow of nutrients between different types of organisms which can help us understand the energy transfer as described before.
Explanation:
Food webs in an ecosystem involves the combination of two or more food
chains. This involves all the relationship an organism has with the others.
This makes the food web complex.
Food webs have different types of organisms present which ranges from
plants which are regarded as the primary producers to animals such as Lion
which can be regarded as a Secondary/tertiary consumer in the ecosystem.
The occasional change in the geography and seasons in the ecosystem
also makes it very complex as some animals exhibit different traits when
subjected to certain conditions. This makes analysis of energy flow and relationship sketchy to determine.

The climate changes on Earth tend to be self-amplified. For example, the Earth is
currently going through a warming trend. As the Earth's temperature rises, the ice caps
and sea ice melt, reflecting less solar radiation. This results in more absorption of the
Sun's heat, causing the Earth's temperature to rise more, and the ice to melt more. This is
an example of what type of system?
Answer:
negative feedback
Explanation:
This is an example of negative feedback system.
What do you mean by negative feeback?Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.
Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.

Which spheres of Earth are directly influenced when human-caused air pollution leads to acid rain that dissolves limestone rocks?
atmosphere, cryosphere, geosphere
cryosphere, hydrosphere, biosphere
geosphere, atmosphere, hydrosphere
biosphere, atmosphere, cryosphere
Answer:
Atmosphere, Geosphere and Hydrosphere
Explanation:
The spheres of earth that get influenced by the human-caused air pollution which leads to acid rains that dissolves the limestone rocks are the atmosphere, geosphere, and the hydrosphere.
This is because the atmosphere contains polluted air which has the components of acid rain. The acid rains accumulate on the hydrosphere if not collected by the geosphere. The geosphere is the one that is drastically affected by the acid rains as the limestone rocks melt.
The atmosphere, geosphere, and hydrosphere are the three spheres of the planet that are affected by human-caused air pollution, which causes acid rains to dissolve limestone rocks.
What is Acid rain?This is because acid rain is caused by contaminated air, which is present in the atmosphere. If the geosphere does not catch the acid rains, they build on the hydrosphere. As the limestone rocks melt as a result of the acid rains, the geosphere is the one that is most severely impacted.
Any type of precipitation with high concentrations of nitric and sulfuric acids is referred to as acid rain.
Snow, fog, and minuscule pieces of dry material that fall to Earth can likewise represent it. Acid rain typically has a pH between 4.2 and 4.4, whereas normal rain has a slightly acidic pH of 5.6.
Therefore, The atmosphere, geosphere, and hydrosphere are the three spheres of the planet that are affected by human-caused air pollution, which causes acid rains to dissolve limestone rocks.

Polymerase Chain Reaction (PCR) technology is used for
a. DNA identification
b. DNA repair
c. DNA amplification
d. DNA cleavage
Answer:
The correct answer is c.
Explanation:
Polymerase Chain Reaction (PCR) technology is an in vitro enzymatic method that allows the amplification of a specific DNA sequence, that is, it is the DNA amplification technique by means of the polymerase chain reaction (PCR) is a technique that consists of the in vitro amplification of a specific DNA fragment. To carry out the amplification experiment, it is necessary to know, at least partially, the sequence of the fragment to be amplified (a gene, a part of a gene, a non-coding region, ...). Basically, it is about replicating the same DNA fragment over and over again and, for this, we must do in vitro what cells do in vivo to replicate their DNA. Generally, PCR begins with the denaturation or separation of the DNA double helix by heating the sample to a temperature between 94 and 96 ° C to break the hydrogen bonds that joined them, in this way each chain remains as a template for the synthesis of a new complementary strand of DNA.

The process of meiosis is essential in the sexual reproduction and life cycle of many organisms. The outcome of meiosis is haploid gametes. Which statements correctly describe the importance of meiosis to the life cycle or these organisms?
A) Increasing genetic diversity ensures that no two haploid gametes are exactly the same.
B) Taking a diploid cell to its haploid state occurs during the first cell division of meiosis.
C) Checkpoints during meiosis ensures that chromosome separation occurs accurately, avoiding non-disjunction.
D) DNA synthesis occurs before each cell division in meiosis ensures that the integrity of the chromosomes is maintained.
E) Reducing the number of chromosomes by half during meiosis ensures the chromosome number is maintained during fertilization.
Answer:
E) Reducing the number of chromosomes by half during meiosis ensures the chromosome number is maintained during fertilization.
A) Increasing genetic diversity ensures that no two haploid gametes are exactly the same.
Explanation:
Meiosis is a kind of cell division that strictly occurs in sexually-reproducing organisms. It is the process whereby four daughter cells that are genetically different from their parents are produced. In meiosis, the chromosome number of each daughter cell (gamete) is reduced by half. As highlighted in this question, the meiotic process is essential in the sexual reproduction and life cycle of many organisms.
This importance is attributed to the fact that:
- Reducing the number of chromosomes by half during meiosis ensures the chromosome number is maintained during fertilization. That is, a diploid organism (2n) produces a haploid gamete (n), which becomes diploid again when fertilized by another gamete.
- Increasing genetic diversity ensures that no two haploid gametes are exactly the same. This occurs because of a process called CROSSING OVER, which enables that the alleles of each gamete is recombined to be different from one another in order to promote genetic diversity.

A cluster of cases of legionellosis have occurred in your neighborhood. People with the illness have cough, fever, shortness of breath, chest pain and sometimes diarrhea. The illness is caused by the bacterium Legionella pneumophila, a facultative intracellular parasite that survives in certain ameba. The organism has an absolute requirement for L-cysteine. Typically, the organism is grown on buffered charcoal yeast extract (BCYE) agar. In some labs, samples containing suspected L. pneumophila are cultured on traditional BCYE medium as well as BCYE medium lacking L-cysteine. How would L. pneumohila be identified in this situation
Answer:
The correct answer is - comparing the presence of an essential component of the L. pneumophila that is cysteine.
Explanation:
As we know that L-cysteine is essential for the organism L. pneumophila to grow its colonies. The identification is easy in this situation by comparing the two cultured on the traditional BCYE medium and BCYE medicum without L-cysteine.
Colonies that grow on traditional BYCE medium are likely L. pneumophila as they required L-cysteine but not on BYCE medium lacking cysteine.
Which adaptation allows reptiles to live entirely on land check all that apply
Reptiles' capacity to deposit amniotic eggs is the main trait that enables them to live exclusively on land. Amniotic eggs have a protective shell around them and include specific membranes that give the growing embryo a self-contained aquatic environment. Amniotic reproduction is the name given to this adaptation.
The amniotic egg has a number of crucial characteristics that let it thrive on land. These qualities consist of:
Shell: By minimizing water loss, the embryo's shell protects it physically and keeps it from desiccating (drying out).
Amnion: The amnion is a membrane that covers the embryo and holds amniotic fluid, which acts as a cushion and source of buoyancy.
The chorion is an additional membrane that encircles the amnion. By facilitating gas exchange, it allows carbon dioxide to leave and oxygen to enter the egg.
The allantois is a sac-like organ that aids in breathing and stores metabolic waste products from the developing embryo.
Egg yolk sac: The yolk sac is a source of proteins, lipids, and minerals that feed the growing embryo.

Oxaloacetate is a key intermediate in the citric acid cycle, but it is also needed as a precursor for the synthesis of glucose during gluconeogenesis. Oxaloacetate is also fairly chemically unstable and undergoes spontaneous decarboxylation to pyruvate. Although oxaloacetate is not depleted by participation in the citric acid cycle, it can become depleted by other processes, necessitating its replenishment by various synthetic pathways. Use the Metabolic Map to identify enzymes that can replenish oxaloacetate or other citric acid cycle intermediates.
Answer:
Carboxylating pyruvate into oxaloacetate.
Explanation:
Replenishing oxaloacetate is done by carboxylating pyruvate into oxaloacetate through a process that is catalyzed by an enzyme called pyruvate carboxylase. This enzyme speed up the process and the replenishing of oxaloacetate occur quickly and the oxaloacetate is ready to function and participate in different chemical reactions.
Depleted oxaloacetate can be replenished by the carboxylation of pyruvate by the enzyme pyruvate carboxylase.
What is the citric acid cycle?The citric acid cycle is a cycle which is important in aerobic respiration for the production of ATP.

why doesn't the periosteum cover the articular cartilage of a long bone
The periosteum does not cover the articular cartilage of a long bone because it is not located in the part of the bone where the joint is formed.
The main function of articular cartilage is to facilitate the movement of a joint in any mechanical circumstance.
The periosteum is a membrane that is part of the constitution of the bones, and that is located throughout the entire bone body, with the exception of the area that is destined for the articular surface.
It is found throughout the central part of the bone, that is, it passes through the entire diaphysis and reaches the metaphysis.
It disappears in the epiphysis because it is the area that generates contact with the tissues that make up the joints, necessary for movement.
Therefore, we can conclude that the periosteum is a membrane that covers all the bones, except the area that is destined for the articular surface.
