Answer:
B
Explanation:
Margaret has detached earlobes (a) , which is a recessive trait. If she wanted ALL of her children to have attached ears (A), what type of man would she need to marry in order to give her the best chances?
A. A man with the genotype AA
B. A man with the genotype aa
C. A man with lobed ears like hers
D. A man with the genotype Aa
Margaret can have all her children with attached earlobes only if she marry a man with AA dominant genotype.
As given,
Margaret has detached earlobes (a) which is a recessive trait If she wanted all of her children to have attached ears (A) if she have to marry a man with the dominant trait
Punnett' square:
A A
a Aa Aa
a Aa Aa
[Aa] are the genotype with attached earlobes [dominant genotype]
Therefore, Margaret can have all her children with attached earlobes only if she marry a man with AA dominant genotype.

How does the DNA sequence in a normal hemoglobin gene compare to a sickle cell hemoglobin gene?
ASAP
Answer:A person with normal hemoglobin has inherited one allele for normal hemoglobin from each parent and so has the genotype Hb A/Hb A. In contrast, a person who has sickle disease has inherited one sickle-cell allele from each parent and has the genotype Hb S/Hb S.
Explanation:
The DNA sequence in a normal hemoglobin gene is different from the hemoglobin gene of sickle cell due to a change in nucleotide base from A to T.
What is Sickle cell anemia?Sickle cell anemia is a group of disorders which cause the red blood cells (RBCs) to become misshapen and break down. It is an inherited group of disorders, in which the red blood cells contort into a sickle shaped cell. The cells die early due to this disorder, leaving a shortage of healthy red blood cells in the blood and can block the blood flow causing pain and crisis.
Symptoms of sickle cell anemia include infections, pain and fatigue.
Genetic studies have shown that the base sequence in the normal hemoglobin (HbA) and the sickle cell hemoglobin (HbS) differs at only a single nucleotide position including a change from an A to a T nucleotide base. This change in nucleotide to one codon results in a single amino acid change in the hemoglobin.

Poison dart frogs live in the rainforest. They produce a poison by eating toxic fire ants. The only known predator is a snake, Liophis epinephelus. Which is most likely a density-independent factor that affects the poison dart population in the rainforest? clear cutting the rainforest limited food source susceptibility to disease increase in population of Liophis epinephelus
Answer:
Clear-cutting the rainforest
Explanation:
Density-independent factors of a population are factors that limit the size of a population irrespective of the density of the population.
A limited food source can only be defined by the size of a population, diseases will spread faster in high-density populations, and an increase in the population of a predator will cause a decrease in the population size of the predator's prey.
Clear-cutting of the rainforest means automatic destruction of the habitat of the poison dart frog's population, no matter the population size. Hence, clear-cutting of the rainforest is considered as the density-independent factor in this case.
Answer:
A.) clear cutting the rainforest

What group of organisms is found at the base of every energy
pyramid?
Answer:
Plants or other photosynthetic organisms (autotrophs) are found on the first trophic level, at the bottom of the pyramid. The next level will be the herbivores, and then the carnivores that eat the herbivores. The energy pyramid (Figure below) shows four levels of a food chain, from producers to carnivores.

Which graph represents selection that may lead to reduced variation in a population? A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population and population after selection have similar curves, but the original population peaks before the population after selection. A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The population after selection increases, decreases, increases, and then decreases again. The original population increases at the point that the original population drops. A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population peaks at the same time as the population after selection but the population after selection peaks higher and at a more rapid speed. A graph has trait value on the horizontal axis and proportion of individuals on the vertical axis. The original population and population after selection have similar curves but the original population is slightly higher at all points. Mark this and return

Do plants need to eat?Or do they acquire energy through a method different from animals?Write down the differences on how a tree and an ostrich acquire the energy they need for survival.
Plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.
What are Autotrophs?
Autotrophs are the organism that can produce its own food using light, water and carbon dioxide or some other chemicals. They are also known as primary producers.
The most familiar type of autotrophs are plant but apart from plants many different types of autotrophic organisms are there. For example, algae which live in water, phytoplankton which live in ocean and some type of bacteria.
Mostly autotrophs used the process called photosynthesis to make their own food. In this process, Autotrophs used energy from the Sun to convert water obtained from the soil and carbon dioxide obtained from the air to produce a carbohydrate called Glucose . It give energy to the plant.
Some rare autotrophs produces food through a process called Chemosynthesis . In this process, they make their own food using energy from chemical reaction combining Hydrogen Sulphide or Methane with oxygen . Organism that uses Chemosynthesis for making their food lives in extreme environment . For example, Bacteria live in active volcanoes oxidize sulphur to produce their own food.
Thus, plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.

When unnatural pollutants are exposed to sunlight and heated up, they create ozone. The correct option is a.
What are unnatural pollutants?
It is the resulting pollution from human activity. It covers the use of fossil fuels in manufacturing, transportation, and thermoelectric power plants, as well as industrial gas emissions, mining, processing, and stone crushing.
The physical degradation or contamination of the environment caused by the release of hazardous, dangerous, or toxic chemical substances is known as pollution.
Oxides of nitrogen (NOX) and volatile organic compounds (VOC), commonly referred to as hydrocarbons, undergo chemical interactions that result in ozone. Both close to the earth and high in the atmosphere, this reaction is possible.
Therefore, the correct option is a. ozone.
