Answer:

combine to form like traits

Explanation:

the genes are made from DNA which is made from chromosomes which hold the dominant and recessive traits of and offspring(s) (if this was incorrect, I apologize)

1) If the individual with the dominant phenotype has a parent with the recessive phenotype, the genotype of the individual is heterozygous (Aa).
2) If the individual with the dominant phenotype has offspring with the recessive phenotype, the individual must be heterozygous (Aa).

The two situations on a pedigree that would allow you to determine the genotype of an individual with the dominant phenotype.

By analyzing the presence of the recessive phenotype in the parents or offspring of an individual with the dominant phenotype, we can determine their genotype as heterozygous (Aa).

Answer:

- Binomial nomenclature is a widely accepted naming system, which is used in the naming of living things. Multiple native names make it extraordinarily tough to establish an organism globally and maintain an observation of the variety of species. Thus, it creates quite a lot of confusion. To eliminate this confusion, a normal protocol came up. According to it, every organism would have one scientific title which might be utilized by everybody to establish an organism.

What is binomial nomenclature?

Binomial Nomenclature follows a universally accepted naming system, which is used to provide a scientific name to a known organism.

Binomial Nomenclature also known as the binary nomenclature.

It uses two-terms during the nomenclature of a specie (plants, animals, and living organisms) that is why it called two-term naming system.

The scientific name of an organism or binomial nomenclature consists of two words, such as the generic epithet and describes the genus and the specific epithet and refers to the species of the organism.

Both of this term is written in italic and the genus name is capitalized.

Binomial nomenclature was given by Swedish botanist and physician Carl Linnaeus. He also called the founder of modern taxonomy.

Carl Linnaeus described and classified thousands of species of plants and animals in his book Systema Naturae.In this technique, there are particular guidelines that are followed while naming organisms. This normal algorithm is relevant to plants and animals whereas giving them distinctive names inside a given system.There are two worldwide codes such as the International Code of Botanical Nomenclature (ICBN) deal with the biological nomenclature for plants and the International Code of Zoological Nomenclature (ICZN) deal with the biological nomenclature of animals.

These two codes agreed upon by all of the biologists over the world for the naming protocol. These codes ensure that every organism will get a selected identity and that identity is globally recognized.

Summary of the limitation binomial nominclature:

- Some of the main drawbacks of binomial nomenclature are: If two or more names are actually in use in compliance with the priority rule, the appropriate name will be used first and the other names will end up being synonyms because authenticity is synonymous with the senior.

Secondary succession is the kind of succession that might develop in a neighborhood park after the Zombie Apocalypse if the grass wasn't cut anymore and pioneer species would first colonize the bare soil.

Thus, pioneer species like weeds and grasses would colonize the bare soil and disturbed regions in the initial stage of secondary succession. These species can swiftly adapt to a new habitat since they are frequently resilient and rapidly developing.

In secondary succession, the pioneer species are the early settlers multiply and spread, the soil conditions become more stable and draw in additional species like shrubs and tiny trees. These animals are modifying the environment in a way that makes it possible for bigger and more diversified populations of creatures to live in more complicated settings.

Answer:

Lighting a match

Explanation:

Lighting a match and letting is burn is an example of a chemical change because the two reactants (fire and the match) form a new substance. Freezing water, melting ice and crushing a rock are physical changes because they only change in size, shape or form.

Chemical reactions that simulate cellular respiration follow the Law of Conservation of Matter when they are balanced. Six carbon atoms, 12 hydrogen atoms, and 18 oxygen atoms are the same number of atoms as the reactants.   C₆H₁₂0₆+60₂ — 6C0₂+6H₂0 .

Through the process of cellular respiration, organisms mix oxygen with food molecules, directing the chemical energy contained in these substances toward life-sustaining processes while excreting carbon dioxide and water as waste. Foods are broken down by organisms that do not require oxygen in a process known as fermentation.

A chemical element is uniquely defined by its atoms, which are small units of a substance. An atom is made up of a core nucleus and one or more negatively charged electrons that orbit it. The positively charged, comparatively hefty protons and neutrons that make up the nucleus may be present. The fundamental building components of matter are atoms. Atoms make up anything that has mass and occupies space.

When a controlled experiment is not possible, why do scientists try to identify as many relevant variables as possible ? You want to find more variables because you need to find the relevant variable in order to identify what is causing the change.

Explanation:

Answer:

Explanation:

When a controlled experiment is not feasible, scientists attempt to identify as many relevant variables as possible because it helps them understand and account for potential confounding factors that may influence the observed outcomes. Here are a few reasons why scientists aim to identify relevant variables:

Reduce Bias: By identifying and accounting for relevant variables, scientists can minimize bias in their observations and analyses. Bias occurs when factors other than the one being studied affect the results, leading to inaccurate or misleading conclusions. Identifying relevant variables allows scientists to control for their potential influence, increasing the reliability of their findings.

Improve Validity: Validity refers to the accuracy and truthfulness of research findings. By identifying and considering relevant variables, scientists can enhance the validity of their research by ensuring that they are examining the actual relationships and effects they intend to study. This strengthens the reliability and generalizability of the results.

Enhance Understanding: Identifying relevant variables can provide a more comprehensive understanding of the phenomena under investigation. It allows scientists to explore potential underlying mechanisms, interactions, and contextual factors that may influence the observed outcomes. This deeper understanding contributes to the advancement of scientific knowledge.

Inform Future Research: Identifying relevant variables, even in non-controlled settings, can guide future research endeavors. By documenting and considering various factors that may impact the research outcomes, scientists can identify areas that require further investigation. It helps in designing more controlled experiments or observational studies in the future to specifically target those variables of interest.

Strengthen Recommendations and Interventions: In fields such as public health or policy research, identifying relevant variables can lead to more informed recommendations and interventions. Understanding the broader context and factors that influence outcomes allows scientists to develop more effective strategies to address the issues at hand.

In situations where controlled experiments are not possible, identifying relevant variables helps scientists better navigate the complexity of real-world scenarios. It allows them to account for confounding factors, improve the robustness of their findings, and contribute to a more nuanced understanding of the research topic.

Explanation:

Computer models are scientific models that help in analyzing complex systems. Scientists use these to analyze data and on the basis of these data computer models are able to predict the outcome of the problem or can tell what will happen in the future.

These are very helpful in complex systems and are made on the basis of the data collected and are the basis of the models. Weather forecast can be predicted on the provided data.

The interference if: distance between a and b is 10mu distance between b and c is 15mu observed double crossover rate is:

[0.0025 - (150 / (AC + 25))] ÷ [1 - (150 / (AC + 25))

= 0.25%

The crossover rate is the rate of return (also called the weighted average cost of capital) at which the net present values ​​(NPV) of the two projects are equal. It represents the rate of return at which the NPV profile of one project intersects with the NPV profile of another project.

In the capital budgeting analysis exercise, crossover rates are used to show when one investment project becomes better than another due to changes in the rate of return (cost of capital).

Now,

The interference can be determined using the following formula:

interference = (observed double crossover rate - expected double crossover rate) ÷ (1 - expected double crossover rate).

The expected double crossover rate can be calculated using the formula:

expected double crossover rate = (distance AB × distance BC) ÷ total distance (AB + BC + AC).

Given:

Distance between A and B is 10mu;

Distance between B and C is 15mu;

Observed double crossover rate is 0.25%.

Therefore,

Distance AB = 10mu;

Distance BC = 15mu;

Total distance = AB + BC + AC

Expected double crossover rate = (10 × 15) ÷ (10 + 15 + AC)

expected double crossover rate = 150 ÷ (AC + 25)

The observed double crossover rate is 0.25%.

Therefore, the observed double crossover rate = 0.25% = 0.0025.

Interference = (observed double crossover rate - expected double crossover rate) ÷ (1 - expected double crossover rate)=

[0.0025 - (150 / (AC + 25))] ÷ [1 - (150 / (AC + 25))

Multicellular organisms have developed specialized tissues and systems that are responsible for completing a limited number of nutrient and waste tasks.

In single-celled organisms such as protistan and small multicellular organisms, vital molecules will move to where they're needed by diffusion. Once an organism is behind a certain size, it cannot get crucial molecules into and out of cells solely by diffusion.

For small multicellular organisms, diffusion beyond the outer membrane is sufficient to meet their oxygen needs. Gas trade by direct diffusion across surface laminate is efficient for organisms less than 1 mm in diameter.

Yes, it is true that pitcher plants are carnivorous. Pitcher plants are a type of carnivorous plant that have evolved to obtain essential nutrients from insects and other small organisms.

The answer in True.

These plants typically grow in nutrient-poor soil conditions and have adapted to capture and digest insects as a way to supplement their nutrient intake.
The main feature of pitcher plants is their modified leaves, which form a pitcher-like structure. This structure is filled with a liquid that contains enzymes and other substances that can break down the captured prey. The rim of the pitcher, called the peristome, is slippery, causing insects to fall into the trap. Once trapped, the insects are digested, and the nutrients are absorbed by the plant.
There are several types of pitcher plants, including the North American Sarracenia, the tropical Nepenthes, and the Cephalotus from Australia. Each species has unique adaptations and trapping mechanisms that help them capture different types of prey.
In summary, pitcher plants are indeed carnivorous, as they have adapted to obtain essential nutrients from insects and other small organisms. They do so through their unique pitcher-like structures, which are designed to trap and digest prey. This adaptation allows them to thrive in nutrient-poor soil conditions.
