YyLl: 400
Yyll: 100
yyLl: 100
yyll: 400
1. Which offspring are the recombinant offspring in this cross?
The parents here are YyLl (heterozygous parent with dominant traits) with yyll (homozygous parent with recessive traits). The recombinant species are yyLl: 100 and Yyll: 100.
What is the dominant and recessive genotype ?The genetic expression that expresses itself are the genetic traits that get expressed in the individual whereas the one that do not are called as recessive genotype.
Here, YyLl is the heterozygous dominant species where Y represents the dominant trait over y and T represents the dominant trait over t. The traits are presented both as dominant and the recessive parents is yytt.
Recombinant species will show traits that are both mixed where the heterozygous dominant and the recessive traits gene will express itself and these are Yyll: 100 and yyLl: 100.

Nerve cells that direct muscles and glands are known as ____________________ neurons. Nerve cells that carry information (pain, temperature, etc) from the body to the brain are called ____________________ neurons.
Answer:
1.Effectors/motor neurons
2. sensory
Nerve cells that direct muscles and glands are known as motor neurons, nerve cells that carry information (pain, temperature, etc.) from the body to the brain are called sensory neurons. Sensory neurons sense the stimulus that our body gets from the external environment.
What are the different types of neurons?Neurons make up the nervous system that conducts the impulse from the original site to the brain and spinal cord, and the neuron can either be a sensory or motor neuron. The nerve cell in a sensory neuron is stimulated by pain or temperature and converts it into an impulse that travels from the site of the organ to the spinal cord and brain, and after receive it, the action is sent to the effector organs. These muscles and glands respond to stimuli by producing actions.
Hence, Nerve cells that direct muscles and glands are known as motor neurons, nerve cells that carry information (pain, temperature, etc.) from the body to the brain are called sensory neurons.

Estimate the probability of this disorder occurring in the offspring of a marriage between first cousins. Enter your answer as either a fraction or a decimal. Part B Compare this probability to the population at large. Inbreeding increases the probability of this disorder. Inbreeding decreases the probability of this disorder. Inbreeding does not change the probability of this disorder.
Part A -The likelihood of having Autosomal Recessive Disorder is 1 in 10,000 people = 0.0001.
Part B - Inbreeding increases the probability of disorder.
Autosomal Recessive Disorder inheritance is the way genetic traits or conditions are passed from parent to child. Genetic conditions can occur when a child inherits a mutated (altered) copy of the gene from each parent. Parents of children with an autosomal recessive disorder usually do not have the disorder. Consanguineous offspring may be at increased risk for recessive diseases due to the expression of autosomal recessive gene mutations inherited from a common ancestor.
The following Genotypes can be found in the first two cousins:
A stands for dominant allele.
a denotes a recessive allele.
1) AA X AA
Normal for all offspring.
There are no problems.
2) AA X Aa
Genotype of offspring = AA and Aa.
Because the phenotype is normal, the condition does not exist.
3) Aa X Aa
Genotype of offspring = AA, Aa, and aa.
The condition affects one-quarter of all offspring.
1/4 are typical,
Half of them are carriers.
4) aa X aa
All offspring are afflicted by the condition.
If we assume the cousins to be carriers[because their genotype is not indicated, we will consider them to be carriers], affected kids are generated.
Carriers' probability = 0.02
By 1/2, both cousins are carriers.
And the likelihood that the child may be impacted - 1/4 or 25%
Total Probability is equal to 1/2 * 0.02 * 1/2 * 0.02
= 0.0001
As a result, the pair might have afflicted offspring by 0.0001.
Possessing the normal alleles has no effect on 25% of people; carrying one impacted and one unaffected allele has no effect on 50% of people. Carrying the afflicted Alleles affects 25% of the population.

Answer:
The kingdom Plantae consists of four major plant groups on land: bryophytes (mosses), pteridophytes (ferns), gymnosperms (cone-bearing plants), and angiosperms (flowering plants). Plants may be categorized as vascular or nonvascular. A vascular plant has tissues for transporting water or sap. Nonvascular plants do not.
Lipids include triglycerides, phospholipids, and ____.
A. steroids
B. amino acids
C. starches
D. nucleic acids
The gonads and adrenal glands typically generate the natural steroid hormones from cholesterol. Lipids are the hormones in these forms. Thus, option A is correct.
What is the role of lipid in the body?Lipids serve as the body's energy reserve, control hormones, carry nerve signals, protect key organs, and transport nutrients that are fat-soluble.
Food fat gives texture and flavor, has a high caloric density as an energy source, and helps people feel full.
The body naturally creates hormone-like chemicals, but steroids are synthetic copies of such substances.
They go by the name corticosteroids and are distinct from the anabolic steroids used by athletes and bodybuilders.

Analyze the relationship between a hypothesis and a theory.
Answer:
A hypothesis is just a plausible explanation for an observable phenomenon. This hypothesis can be tested (called hypothesis testing). A hypothesis must be a) falsifiable/disprovable, b) testable, and c) have predictive value. A hypothesis gains validation when there is significant evidence in favor of that hypothesis. A theory is a hypothesis (or a group of hypotheses) with significantly large amount of evidence (consisting of repetitions of the experimental results in by different groups of scientists). Then the theory is able to explain verified proven facts.

Select a region of the world and explain how its latitude, elevation, geographical features, and relationship to winds and ocean currents determine its climate.
We are attempting to explain how Ecuador's latitude, elevation, geographic characteristics, and interaction with winds and ocean currents affect its climate.
Geographical Effects:For every 100 meters of elevation, the temperature typically drops by 1°C. In comparison to land, oceans heat up and cool down far more slowly. This means that, at the same latitude and elevation, seaside areas are warmer in the winter and more laid-back in the summer.
By moving warm water and precipitation from the equator to the poles and cold water from the poles back to the tropics, ocean currents function much like a conveyor belt. In order to balance out the uneven distribution of solar energy reaching the Earth's surface, ocean currents govern the global climate.

Explanation:
A plant stem's two main functions are to support the leaves and to transport materials
between roots and leaves. As a stem develops, it possesses three types of permanent
tissues: surface tissue, ground tissue, and vascular tissue. The surface and ground
tissues support and give structure to the plant. The vascular tissues are the transport
systems of the plant. The vascular tissues usually exist in one of three patterns and are
known as the phloem and xylem.
Both the xylem and phloem are made up of several different types of cells that make up
transport tubes for needed nutrients. In general, xylem nutrients (sap) travel from the roots
to the rest of the plant. Phloem sap is derived from photosynthesizing leaves and from
there is carried throughout the plant.
What would we be able to study by injecting a nutrient dye into the root of a plant?
