A polygenic trait is only controlled by one environmental factor.
WILL POST ANSWER IN COMMENTS
Answer:
A polygenic trait is controlled by multiple genes and influenced by the environment.
Explanation:
A Polygenetic trait is a group of non-epistatic genes that interact to influence a trait. Essentially, in short terms Polygenetic traits are controlled by multiple genes rather then an individual inherit gene.
Hope I helped,
Brainliest is always appreciated.
Answer:
B: A polygenic trait is controlled by multiple genes and influenced by the environment
Explanation: For anyone who wants/needs an explanation
Polygenic traits basically mean the traits that are a result of multiple intertwined traits like for example skin colour.
When two people mate their traits get intertwined and the resultant trait of the baby is a result of the polygenic traits.
Polygenic traits are controlled by more than one genes. An example of this on humans is height. Not one gene controls the height of a human, many traits contribute to the height of a human.

Summarize any four ways prokaryotes are important or helpfull to the environment and human
Answer:
Prokaryotes are important to all life on Earth for a number of reasons.
Explanation:
They play a critical role in the recycling of nutrients by decomposing dead organisms and allowing their nutrients to be re-used.
They are also important for many metabolic processes. Bacteria in our guts and mouth help with the digestion of food by breaking down difficult to digest carbohydrates and other compounds. Recent research has suggested that the microbial community in our guts can be a significant factor contributing to obesity.

The homologous chromosomes separate during ____________________ and their sister chromatids separate during _____________ phase of meiosis.
Answer:
anaphase I chromosomes separate
anaphase II sister chromatids separate
Prophase I and metaphase I are the first two stages of meiosis I, respectively. Two kinetochore microtubules from each of the two opposite poles bind to the bivalent chromosome's centromere during anaphase II.
What are the characteristics of anaphase I and anaphase II?The centromeres of each chromosome simultaneously separate during the anaphase II stage of meiosis II, and the sister chromatids are drawn apart in the direction of the opposing poles.
A microtubule network referred to as the spindle apparatus is used to transport chromosomes to both poles of a meiotic cell at this stage. Through this technique, two distinct groups of homologous chromosomes are formed.
Therefore, The homologous chromosomal pair's individual kinetochore-microtubules are joined to each chromosome during anaphase 1.

Which type of genetic disorder cannot be predicted by a Punnett Square?
A single-gene disorder
B sex-linked disorder
C random mutation
Random mutation is a type of genetic disorder which cannot be predicted by a Punnett Square. Therefore, option (C) is correct.
What is a Punnett Square?A Punnett Square is a tool used in genetics to predict the probability of inheriting specific traits or genetic disorders. It is named after Reginald Punnett, a British geneticist who developed this method. The Punnett Square is typically used for single-gene disorders, which are caused by mutations in a single gene. By crossing individuals with known genotypes, the Punnett Square can help determine the likelihood of offspring inheriting a specific disorder.
However, it is important to note that Punnett Squares are not applicable for all types of genetic disorders. They are most useful for disorders inherited in a Mendelian pattern, where a single gene controls the trait. Other types of genetic disorders, such as those caused by random mutations or complex interactions between multiple genes and environmental factors, cannot be accurately predicted using a Punnett Square alone. These types of disorders often require more complex genetic testing and analysis.

The skeletal muscles are innervated by a single motor axon.
What do you mean by Skeletal muscles?Skeletal muscles may be defined as a muscle that is connected to the skeleton to form part of the mechanical system. These muscles perform a wide range of movements and functions.
Each skeletal muscle fiber is innervated by a single motor axon. The same axon may also innervate other muscles fibers. It is also referred to as a motor unit.
Therefore, the skeletal muscles are innervated by a single motor axon.

When looking at the sequence of a variety of genes, which species' genes would you predict to have the most similar sequence compared to the corresponding genes in humans
Answer:
Explanation:
One of the most important aspects of bioinformatics is identifying genes within a long DNA sequence. Until the development of bioinformatics, the only way to locate genes along the chromosome was to study their behavior in the organism (in vivo) or isolate the DNA and study it in a test tube (in vitro).

B. In an egg cell
C. In a tadpole
D. In a bacterium
⭐Pls help me Fast!⭐
As stated in the preceding statement You will most probably find specialized tissue in bacteria.
The correct option is D.
Definition of a bacteria in simple terms:The simplest single-celled organisms are known as bacteria, and they are invisible to the unaided eye. Various animals, including humans, include a wide variety of microbes both inside and outside. Additionally, bacteria are vital components of the Earth's ecosystems since they are present in food, water, soil, and surfaces.
What distinguishes a bacterium from a bacteria?The word "bacteria," which is plural, is spelled "bacterium." To put it another way, you use the word "bacteria" when there are multiple of them and "bacterium" and there is only one.
Why do bacterial infections occur?When bacteria taken into the body, multiply, and trigger an immune response in the body, a bacterial infection results. Through an opening within your skin, such as a cut or surgical wound, either through your airway, germs can enter your body and cause diseases like bacterial pneumonia.
