Mendel evaluated in his pea plants were each expressed as one of two versions, or traits. Mendel deduced from his results that each individual had two discrete copies of the characteristic that are passed individually to offspring. We now call those two copies genes, which are carried on chromosomes. The reason we have two copies of each gene is that we inherit one from each parent. In fact, it is the chromosomes we inherit and the two copies of each gene are located on paired chromosomes. Recall that in meiosis these chromosomes are separated out into haploid gametes. This separation, or segregation, of the homologous chromosomes means also that only one of the copies of the gene gets moved into a gamete. The offspring are formed when that gamete unites with one from another parent and the two copies of each gene (and chromosome) are restored.
For cases in which a single gene controls a single characteristic, a diploid organism has two genetic copies that may or may not encode the same version of that characteristic. For example, one individual may carry a gene that determines white flower color and a gene that determines violet flower color. Gene variants that arise by mutation and exist at the same relative locations on homologous chromosomes are called alleles. Mendel examined the inheritance of genes with just two allele forms, but it is common to encounter more than two alleles for any given gene in a natural population.
Describe how a pollutant that is released from the combustion of coal contributes to the formation of acid deposition.
When coal is burned the sulfur mixes with oxygen and the sulfur oxides are emitted to the atmosphere. Sulfur dioxide (SO2) becomes sulfur trioxide (SO3) when responding with oxygen in the air.
How does combustion cause acid rain?Power plants remove the major of sulfur dioxide and of the nitrogen oxides when they burn fossil fuels, such as coal, to make electricity.
The from cars, trucks, and buses remove nitrogen oxides and sulfur dioxide into the air. These pollutants leads acid rain.
Hence, This reaction with water elements in the atmosphere to form sulfuric acid, a strong mineral acid. This makes rain acidic.

Answer:
ITS NOT OPTION A!!
Explanation:
gases do not have a definite shape because?
Answer:
Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around. The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume.
Therefore, gases take the shape of the container and occupy the complete volume of that particular container.
In addition to cortisol, other hormones that are usually released during many kinds of stress include ______.
In addition to cortisol, other hormones that are usually released during many kinds of stress include CRH, aldosterone, catecholamines, and beta-endorphins.
What do you mean by Hormones?Hormones may be defined as a chemical substance produced in the body that governs and regulates the activity of certain cells or organs.
Corticotropin-releasing hormone (CRH) is the central controller of the hypotalamic-pituitary-adrenal axis, which is the major organizer of the body's response to stress.
Catecholamines such as dopamine, epinephrine, and norepinephrine are released in the body during stress.
Beta-endorphins modulate the effect of stress and attenuate its response in the body.
Therefore, in addition to cortisol, other hormones that are usually released during many kinds of stress include CRH, aldosterone, catecholamines, and beta-endorphins.

benefits of variation in height
Answer:
It’s nice to be tall. Tall people are more likely to get hired, get promoted and are paid better than their shorter counterparts. They can reach things from high shelves, have unobstructed views at parades, and are consistently rated as being more attractive than others. Overall seems like a sweet deal.
If you are short, you get depressed when some points out that a study in the New England Journal of Medicine suggested that shorter people are at higher risk for heart disease. However, you might find some solace from a study published in PLOS one that found that shorter people lived longer or another study that suggested that taller people are at increased risk for cancer. When it comes to whether it is better to be tall or short, there is a lot of medical research on the subject, and one half contradicts the other half.
These studies get a lot of media play because they are instinctively popular. We are obsessed with height as a society. After all, we invented high-heeled shoes to defy genetics and punish our ankles.
But every time a report claims that taller is better (or that shorter is better), headline writers seem to consistently forget that six months ago they were claiming the opposite.
But being short i also nice so if someone is making fun for your height its because their insecure about their own height
Answer:
Variation in height creates a diverse and more dynamic world, we need certain heights for certain careers as well as certain tasks.

Karenia brevis, the dinoflagellate responsible for red tides, is ____________ , meaning it can undergo photosynthesis when conditions are right, or it can ingest bacteria, algae, and animal waste if additional nitrogen is needed.
Mixotroph organisms are capable of obtaining energy from the environment by combining autotrophic and heterotrophic mechanisms. Karenia brevis is mixotroph.
What is mixotrophy?Mixotrophy is a nutritional strategy used by some organisms that combine autotrophy and heterotrophy to obtain energy. It is widely observed in aquatic environments and especially among phytoplanktonic flagellated algae.
The development of mixotrophy depends on the environment in which the organism lives, its limiting conditions, and resources availability.
This strategy is used in aquatic environments in which light and nutrients availability is scarce. So organisms can change from being autotrophs to heterotrophs, and vice-versa, according to the environmental pressures.
