Organism a is eukaryotic, unicellular, and lacks a cell wall. Organism b is eukaryotic, multicellular, has cell walls, and is autotrophic. In which kingdoms should these organisms be classified?.
Kingdom Plantae contains species that are autotrophs and have a cellulose cell wall, whereas kingdom Animalia contains organisms that are heterotrophs and lack a cell wall. C is the right response.
An organism that consumes other plants or animals for energy and nutrients is referred to as a heterotroph. The word comes from the Greek terms hetero, which means "other," and trope, which means "nourishment." Based on how they receive their energy and nutrients, organisms are divided into two general categories: heterotrophs and autotrophs. Because they can manufacture their own food from basic materials and energy, autotrophs are referred to as producers. Examples include trees, algae, and some bacterial species. Heterotrophs are referred to as consumers because they eat other consumers or producers. Heterotrophs include animals like dogs, birds, fish, and people.

phenylketonuria is an inherited disease caused by a recessive allele. if a woman and her husband are both carriers, what is the probability that their first child will have the disease?
The answer is ¼. Probability of having a child with a healthy phenotype: Aa x Aa = 3/4 Healthy (half AA, half Aa): 1/4 affected (aa). The sickness will affect one or more of the three kids. All potential outcomes' probabilities must sum up to 1.
If both of them are carriers, PKU must be a hereditary condition with a recessive gene, and the parents must be heterozygotes (Pp).
Pp x Pp
The phenotypes of the genotypes PP and Pp would be typical. The PKU disease's phenotype would be expressed by the genotype pp. Phenylketonuria is a genetic condition known as PKU, and those with it have excessive quantities in their blood. The phenylalanine hydroxylase (PAH) gene mutation is to blame for this. The gene is in charge of the body's breakdown of phenylalanine.
Carriers are heterozygous people who have one copy of the trait's dominant allele and one copy of its recessive allele. The likelihood that kids from two heterozygous individuals would have either a homozygous recessive or dominant genotype is 25% for each. whereas there is a 50% chance of getting heterozygotes.
So, we can say the answer is 1/4. Chance of having a child with a phenotype that is healthy: Aa x Aa = 3/4 Healthy: 1/4 impacted (half AA, half Aa) (aa). One or more of the three children will be impacted by the illness. Probabilities of all possible outcomes must equal 1.

Speckled chicken, created by parent with feather of two different color (ome black and ome White). What are thee chicken an example of?
Hello Kevin,
Here is my answer to your wonderful question down below.
Answer:
Speckled chickens are an example of genetic diversity and codominance.
Explanation:
Meiosis allows genetic diversity since the mother and father have different-colored feathers. If the two mate, then the outcome of the chicken will either be fully black, fully white, or speckled. The chance of having a speckled chicken from parents that are different colors is high.
If you are talking about genetics, codominance refers to a kind of inheritance in which two variants (alleles) of the same gene are expressed separately to produce distinct features in an organism.

air particles bouncing off one another and transferring heat?
O Composition
O Conduction
O Convection
O Radiation
When air particles absorb heat from ground particles, convection occurs and the earth warms the air above it.
How does energy get from the earth to the atmosphere?
Energy is transported from the Earth's surface to the atmosphere in a variety of processes, including radiation, conduction, and convection. Conduction is one of the three main ways that heat energy is transferred. The other two ways that heat is transmitted are through radiation and convection.
The heated surface of the earth heats both the air it comes into touch with and the air above it, creating convective air currents. As a result of heating, the atmosphere expands, reducing atmospheric pressure everywhere. The cooler regions' thick atmosphere causes air from those areas to start moving toward the warmer regions, producing "winds."
