How do environmental factors and heredity affect personal health?
Thanks
Answer:
Heredity: all the traits and properties that are passed along biologically from both parents to child. To some degree this determines your general level of health. You inherit physical traits such as the color of your hair and eyes, shape of your nose and ears, as well as your body type and size.
Explanation:
Brainliest please?

D. Haploid
Answer:
Diploid
Explanation:
Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells. Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half!

How would you know when homeostasis has been reached in your egg and syrup system?
The egg and syrup system
because the egg membrane is semi-permeable, water can flow in however proteins can not flow out. If a egg is positioned in the corn syrup the egg will shrink. this is also because of osmosis, but inside the opposite direction. The corn syrup is more often than not sugar.
What takes place whilst you go away an egg in water for twenty-four hours?
depart the egg within the water for 24 hours. The water will migrate from the side of the membrane wherein water molecules are abundant (outside the egg) o the side where water molecules are less considerable. After 24 hours, the egg will be plump once more.
What takes place whilst you positioned an egg in vinegar then corn syrup?
as the vinegar reacts with the eggshell, bubbles surround the egg, inflicting it to waft. while the egg is placed in the salt water, it sinks to the lowest of the beaker again, considering the fact that it's miles greater dense than the salt water solution. The egg floats inside the corn syrup due to the fact the corn syrup is extra dense than the egg.

What do buffers do and why are they important in biological systems
Explanation:
A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges. Buffer solutions have a working pH range and capacity which dictate how much acid/base can be neutralized before pH changes, and the amount by which it will change.

What are villi and microvilli? What are their funcrions
Answer:
Villi and microvilli are both membranous structures that help facilitate the exchange of materials out and in the cell.
Explanation:
Since they are threadlike projections it increases the surface area while decreasing the volume (that's really good for any cell!). So they both indeed make the exchange of fluids and other materials easier.
How do naturally occurring hormones affect plants?
Answer:
The answer is C :)
Explanation:
explain why it is important to keep the levels of nucleotides relatively balanced in the context of dna and rna synthesis
Answer:
Read Below
Explanation:
Nucleotides are A & T and G&C you see in DNA and in RNA T is Replaced by U. The reason they must be balanced between G&C and T&A is because G has to bond with A in DNA and G with C so if there is more G than C that means there is mismatches between the DNA nucleotides same thing for A and T. In RNA you follow the same rule. If we have lets say 27% of our DNA as A we have to have 27% as T leaving 23% as C and 23% as G. If there was lets say 29% T while one 27% A then there was a error in DNA replication and could lead to errors in RNA synthesis if not corrected

Earth Science: Q14. Explain the principles of the plate tectonics theory.
Answer: Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, which float on the fluid-like (visco-elastic solid) asthenosphere. The relative fluidity of the asthenosphere allows the tectonic plates to undergo motion in different directions.

Why is knowing information about embryo development important?
Answer:
It helps you understand how life forms and what it takes for life to develop as well as the changes through this life cycle
Explanation:
Knowing information about embryo development is important because it helps us to understand how an organism grows and develops from a single cell into a complex being.
Why knowledge about embryo development important?An embryo is the stage of development that follows fertilization and begins when the zygote, a single cell formed by the union of a sperm and egg, begins to divide and differentiate into the various cell types that will make up the organism.
This knowledge can be used in various fields, such as reproductive medicine, to help improve fertility treatments and increase the chances of successful pregnancies. It can also be used in fields such as genetics and evolutionary biology to understand how traits are inherited and how species have evolved over time. Understanding embryo development can also provide insights into the causes of birth defects and developmental disorders, and help researchers develop treatments or interventions to improve the health and well-being of individuals.

Why is retinoblastoma more common in individuals who have inherited the RB deletion and have the genetic predisposition for retinoblastoma?
Answer:
Retinoblastoma is more common in people due to the mutation of RB gene in them.
Explanation:
Retinoblastoma is a disease that affects the eyes of an individual. It is more commonly eye cancer which occurs on the retina of the eye. Retinoblastoma mainly affects younger children.
When the RB gene is mutated or it is deleted already on any one of a homologous chromosomes, then only one hit rather that two which is needed to cause the development of retinoblastoma and hence the probability is of retinoblastoma to occur is higher in the individuals who have already inherited the RB deletion and also have a genetic predisposition for the retinoblastoma.
