Which statement best describes how the environment influences the traits of an individual?
The environment influences the gene expression which can change the genotype.
The environment influences the gene expression which can change the phenotype.
The environment influences only external factors.
The environment influences only internal factors.
Answer: The environment influences the gene expression which can change the phenotype.
Explanation: TRUST
The environment influences the gene expression which can change the genotype. The correct option is A.
What is gene expression?The methodology by which a gene in a cell is activated to produce RNA and proteins.
Gene expression can be assessed by examining the RNA, the protein produced from the RNA, or whatever the protein does in the cell.
The environment can impact gene expression in a life form, along with the outer environment in which the species is positioned or evolves, as well as the organism's internal world, which encompasses factors such as hormones and metabolism.
Several factors influence gene expression, which would include molecules within the cell, mutations that cause dominant damaging consequences and haploinsufficiency, signaling molecules from neighboring cells and the environment, and epistasis.
The environment influences an individual's genotype but not his or her phenotype.
Thus, the correct option is A.

After cytokinesis, how many cells have been formed from the parent cell?
Answer:
The cell now undergoes a process called cytokinesis that divides the cytoplasm of the original cell into two daughter cells. Each daughter cell is haploid and has only one set of chromosomes, or half the total number of chromosomes of the original cell.
Explanation:
The phragmoplast, a structure made up of membranes, actin filaments, and microtubules, controls the deposition of the new wall.
What is the role of cytokinesis in plant cell?Higher plant cells have a unique process for cytokinesis, in which the division of a new cell wall partitions the cytoplasm.
Inside the cell is the cell plate. The location of a preprophase band of microtubules and actin filaments determines where the cell plate is located.
After mitosis, a new cell wall must be created and inserted in plant cells during a process known as cytokinesis.
The cytoplasm of the parent cell is now divided into two daughter cells by a process known as cytokinesis in the cell.
Therefore, each daughter cell is haploid and has just one set of chromosomes, or half as many as the original cell.

Could someone help : how does the number of offspring that are produced by an individual typically compare with the fecundity of that individual? What factors create this (think of reproductive potential)
Answer:
The number of offspring produced is often related to the amount of parental care. Typically, the higher fecundity, the lower the amount of time parents devote to caring for the offspring.
The number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.
What is parental care in the animal kingdom?Parental care refers to the behaviors of parents for the care of their offspring, and in the animal kingdom, parental care can take many forms, ranging from simple behaviors like providing food and shelter to more complex behaviors like teaching and training offspring and parental care is important for the survival and development of offspring, as it can improve an offspring's chances of survival by providing them with resources, protection, and guidance.
Hence, the number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.

which two body systems interact to expel the waste product carbon dioxide
a urinary system
b nervous system
c excretory system
d circulatory system
Answer:
excretory system and circulatory system
Explanation:
Blood is part of circulatory system and as it move through various organs it exchanges the gases i.e give oxygen to the cell and take carbon dioxide from them. After taking CO2, the blood becomes impure and hence it passes through the kidney before going to the heart. Kidney is part of excretory system which removes carbon dioxide from blood and thus purifies it.

Scientist observed an organism X and noted down the mode of nutrition as follows X secretes enzymes outside its body and digests food with these enzymes. It then absorbs the digested food. Which organism was observed by the scientist?
Answer:
Hydra
Explanation:
The mode of nutrition being described in this question is EXTRACELLULAR DIGESTION, in which a food substance is chemically broken down externally. The organisms being portrayed is HYDRA. Hydra is an animal that secretes digestive enzymes that work on the food extracellularly (outside the organism), then absorb the digested food.
Therefore, the organism X observed by the scientist whose mode of nutrition is to secrete enzymes outside its body and digests food with these enzymes, then absorbs the digested food is the HYDRA.

How does the process of gel electrophoresis produce DNA fingerprints? An electric current sorts DNA nucleotides according to their bases. O An electric current cuts a DNA strand into segments of various lengths O An electric current causes segments of DNA to move at different rates O An electric current supplies a charge to uncharged segments of DNA
Answer:
Gel electrophoresis
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.

What unique characteristic does the bonding of carbon to other atoms have and why is this important for organic molecules?
Explanation:
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules. Individual carbon atoms have an incomplete outermost electron shell.The ability of forming long durable chain is an unique characteristic of Carbon that is important for organic molecules.
The Carbon can form four bond with different atom anf form a long chain of different size. These can also be branched. The long chains are very durable.
Silicon and some other elements can do so but the chains are relatively short and non-durable.
Therefore, the ability of forming long durable chain is an unique characteristic of Carbon that is important for organic molecules.
