Which land biome would have a smaller plant and animal population because of its colder climate?

Answer:

A. Amino Acid, protein, gene.

Explanation:

Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.

A gene can be defined as a complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).

A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Simply stated, a sequence of biomolecules which are responsible for coded genetic instructions in all living organisms is known as nucleotides.

Basically, nucleotide comprises of the following parts;

1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.

2. A phosphate group.

3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.

Furthermore, the two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;

I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.

II. Phosphate: this is the structural backbone that provides support to DNA.

Additionally, the proteins which are mainly synthesized based on the genetic instruction codes in deoxyribonucleic acid (DNA) determines the trait of living organisms.

Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.

Hence, when you remove a nucleotide from a gene, the order of nucleotides shifts and as such resulting in new amino acid being coded for. These new amino acid will combine to form a different protein than what the gene was originally coded for.

Explanation:

Actually both are connected by capillaries

Answer:

T always pairs with G

Explanation:

According to the complementary base pairing rule as postulated by Chargaff, an Adenine base (A) will always hydrogen pair with a Thymine base while Cytosine base (C) will always hydrogen pair with Guanine base (G) in a DNA molecule.

That is; A - T and G - C

Hence, based on the question, the pairing of Guanine and Thymine is incorrect.

Answer:

Which of the following situations would be most likely to engage the anterior cingulate cortex?

A waiter walks over to your table at a restaurant and holds an open menu in front of you.

You walk into the elevator of your apartment building and press the button for your floor.

You enter your classroom and find someone sitting in your usual seat.

A good friend asks you to remind him of your telephone number.

Explanation:

In order to meet the demand of the surrounding environment   by adjusting  the  motor outputs from the brain to the environments ,a part of the emotion control part of the brain( limbic system) called the anterior cingulate cortex is responsible for this.

Anatomically, the limbic system is made up of the primarily the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia and cingulate gyrus.

Based on the this its(anterior cingulate cortex) functions are formation of emotion in the limbic system, and  possessing  of memory and learning.

it is also a major  parts of  of pain networks for pain modulation and perception.

Therefore whenever there is  change in the environment  from the prestored condition in the brain,(e.g the usual seat  in the class room  occupied above) the anterior cingulate cortex adjust the motor input from the brain to adapt to the new environment to take an action,whih in this case  leads to the reclaiming of the seat or any other necessary proactive action.

Answer: The three main research methods used are observation, modeling, and experimentation.

Explanation:

Observation:

Every experiment requires observation. Ecologists must observe the environment, the species within it, and how those species interact, grow and change. Different research projects different types of assessments and observations.

Ecologists sometimes use a desk-based assessment, or DBA, to collect and summarize information about specific areas of interest. In this scenario, ecologists are using information already collected from other sources.

Oftentimes, however, ecologists rely on observation and fieldwork. This entails going into the habitat of the subject of interest to observe it in its natural state. By doing field surveys, ecologists can track the population growth of species, observe community ecology in action and study the impact of any new species or other introduced phenomena in the environment.

Each field site will differ in nature, shape, or other ways. Ecological methods allow for such differences so that different tools can be used for observations and sampling. It is crucial that sampling be done randomly to combat bias.

Modeling:

Ecological methods rely heavily on statistical and mathematical models. These provide ecologists with a way to predict how an ecosystem will change over time and react to changing conditions in a system.

Modeling also provides another way to decipher ecological information when fieldwork is not practical. There are several drawbacks to relying solely on fieldwork. Because of the typically large scale of fieldwork, it is not possible to replicate experiments exactly. Sometimes even the lifespan of organisms is a rate-limiting factor for fieldwork. Other challenges include time, labor, and space.

Modeling provides a method in which to streamline information more efficiently.

Examples of modeling include equations, simulations, graphs, and statistical analyses. Ecologists use modeling for producing helpful maps as well. Modeling allows for calculations of data to fill in gaps from sampling. Without modeling, ecologists would be hampered by the sheer amount of data that needs to be analyzed and communicated. Computer modeling allows for comparatively rapid analysis of data.

A simulation model, for example, enables the description of systems that would otherwise be extremely difficult and too complex for traditional calculus. Modeling allows scientists to study coexistence, population dynamics, and many other aspects of ecology. Modeling can help predict patterns for crucial planning purposes, such as for climate change.

Humanity’s impact on the environment will continue. It, therefore, becomes ever more crucial for ecologists to use ecological research methods to find ways to mitigate the effects on the environment.

Experimentation:

The overarching purpose of ecological methods for research is to get high-quality data. Experiments must be carefully planned.

Hypothesis: The first step in any experimental design is to come up with a hypothesis or scientific question. Then, researchers can come up with a detailed plan.

Factors that affect fieldwork experiments include the size and shape of an area that needs to be sampled. Field site sizes range from small to very large, depending on what ecological communities are being studied. Experiments in animal ecology must take into account the potential movement and size of animals.

For example, spiders would not require a large field site for study. The same would be true when studying soil chemistry or soil invertebrates. You could use a size of 15 meters by 15 meters.

Herbaceous plants and small mammals might require field sites of up to 30 square meters. Trees and birds might need a couple of hectares. If you are studying large, mobile animals, such as deer or bears, this could mean needing a quite large area of several hectares.

Deciding upon the number of sites is also crucial. Some field studies might require only one site. But if two or more habitats are included in the study, two or more field sites are necessary.

Tools: Tools used for field sites include transects, sampling plots, plotless sampling, the point method, the transect-intercept method, and the point-quarter method. The goal is to get unbiased samples of a high-enough quantity that statistical analyses will be sounder. Recording information on field data sheets aids in the data collection.

A well-designed ecological experiment will have a clear statement of purpose or question. Researchers should take extraordinary care to remove bias by providing both replication and randomization. Knowledge of the species being studied as well as the organisms within them is paramount.

Results: Upon completion, collected ecological data should be analyzed with a computer. There are three types of ecological experiments that can be made: manipulative, natural, and observational.

The 3 general methods used by ecologists to study organisms include:

Observation involves observing organisms in their natural habitats or environments and then recording the findings. It is usually done by field surveying.

The different species living in an environment, how they interact with each other and other abiotic components of the environment are some of the observations taking during field surveys. The growth of individual species, the effects of introducing new species, their adaptations and other areas of community or ecosystem ecology can be studied through observation.

Modelling requires a simulation of real-life ecological processes through  different manipulations. This could be done in the laboratory, on the field, or even on the computer. Computer modelling requires that data from observation or experimentation are supplied as input and the inputs are subject to mathematical maneuvering.

With models, complex ecological processes can be simulated and analyzed and extrapolated to deduce how things might happen in real life ecological interactions.  

Experimentation involves setting up experiments following the scientific method. It can be a observational or controlled experiments.

Observational experiments requires studying organisms, populations, communities, or ecosystems through pure observation without changing or manipulating any variable.

Controlled experiments requires that variables are introduced and manipulated in some groups while some groups serve as the baseline without any manipulated variables.

Data are obtained from experiments and these are analyzed in relevant ways to support or reject hypotheses.
