When 1 molecule of glucose from glycogen stores is converted to lactate, the net energy gain is 3ATP.
What is anaerobic glycolysis?Anaerobic glycolysis is the pathway of conversion of glucose to lactate in the muscles in the absence of oxygen.In the skeletal muscles, glycogen breaks down to form glucose in the form of Glucose 1 phosphate (G1P).G1P gets converted to G6P.G6P enters glycolysis and produces ATP as energy source in the muscles.2 ATP molecules are produced in this step.When there is enough oxygen, pyruvate releases energy through oxidative phosphorylation.In the absence of oxygen, pyruvate gets converted to lactate by lactic acid fermentation.This lactate then moves into the liver where it gets converted into pyruvate and then glucose. 6 ATP molecules are produced in this step.Learn more about anaerobic glycolysis here:

By the time the fertilized egg reaches the uterus it is a hollow ball of cells called a:________
By the time the fertilized egg reaches the uterus it is a hollow ball of cells called a: Morula
This collection of cells, known as a morula, resembles a little ball by the time it reaches the uterus. The morula develops a hollow interior and fills with fluid to produce a blastocyst. The blastocyst will cling to the endometrium, the uterus' lining, by the end of this week. The term for this is implantation.The zygote, which comes before the blastocyst, is split into the morula, a solid mass with 16–32 blastomeres. At the 8-cell stage, a process known as compaction starts, in which the spherical, loosely linked blastomeres take on a flattened polarized cell shape.learn more about morula here: https://brainly.com/question/11893522

Harold’s wonders how much of a role genetics plays in determining his weight. He has heard about a gene, called leptin. Mice with a defective form of the leptin gene tend to?
Weight is a quantitative trait and mice with defective leptin tend to have problems controlling weight since this gene is associated with it.
What is a quantitative trait?A quantitative trait is a phenotypic feature controlled by many genes and the interaction with the environmental factors.
Weight, height, behavioral features are all examples of quantitative traits because these types of phenotypic features show continuous variation.
Quantitative traits are modulated by gene interactions and therefore exhibit both epistatic and pleiotropic effects.
The leptin gene is a gene in mammal involved in neuronal control to metabolic signals and thereby it is associated with weight.
In conclusion, weight is a quantitative trait and mice with a defective form of the leptin gene tend to have problems controlling weight because it is associated with this trait.

Describe the weather factors that are important in determining where plant and animals can exist in an area. Describe at least three types of weather data that is collected, the instruments used to collect the data, and in what units they are measured. Differentiate between the three major climate zones.
Answer:
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
Explanation:
What is a difference between climate and weather?
Image result for explain the difference between weather and climate.
Weather can change from minute-to-minute, hour-to-hour, day-to-day, and season-to-season. Climate, is the average of weather over time and space. We hear about weather and climate all of the time. Most of us check the local weather forecast to plan our days.
What are the 3 differences between weather and climate in points?
Weather is the combination of temperature, humidity, precipitation, cloudiness, visibility, and wind. In popular usage, climate represents the synthesis of weather; more formally, it is the weather of a locality averaged over some period (usually 30 years), plus statistics of weather extremes
Explanation:
Weather is rain, snow, thunderstorms, hail, etc. Climate is a desert, island, rain forest, etc. Animals and plant's all need different weather and climate. For example a cactus's needs a hot climate and doesn't need a lot of wet weather (rain, snow, hail, thunderstorm, etc)

If a gene exists in 10 different alleles in a population, how many alleles can be expressed in one diploid cell?
If a gene exists in 10 different alleles in a population, two alleles can be expressed in one diploid cell.
What is a diploid cell?
The term "diploid" describes an organism's cells having two full sets of chromosomes, with one chromosome from each parent present in each pair. Since humans are diploid, the majority of their cells have 23 pairs of chromosomes. However, human germ cells (egg and sperm cells) are referred to as haploid since they only have one pair of chromosomes.
Two full sets of chromosomes are present in a diploid cell. The majority of human cells are diploid, with 23 chromosomal pairs totaling 46 chromosomes. This comprises a pair of sex chromosomes and 22 pairs of autosomes. The mother and father each contributed one replica of each pair of chromosomes to the person.
We have two copies of every gene because we have two copies of each chromosome. The majority of mammals, including humans, are diploid, however certain creatures are polyploid or have more than two sets of each chromosome. Consider the octoploid nature of your typical supermarket strawberry, which has eight complete sets of seven chromosomes apiece for a total of 56 chromosomes.
Therefore, two alleles can be expressed in one diploid cell, if a gene exists in 10 different alleles in a population.

What layer of blood vessels is responsible for vasodilation and vasoconstriction as a result of sympathetic activation?
Tunica media is the layer of blood vessels responsible for vasodilation and vasoconstriction as a result of sympathetic activation.
What effect does tunica media have on blood pressure?
The cardiovascular system includes tubular organs called blood vessels that move blood across the body. The organ that provides the pressure required to force the blood through the vessels is the heart. In contrast to veins, which carry blood back to the heart, arteries carry blood away from the heart. The vascular wall of arteries and veins has three layers. The innermost layer of the tunic is called the tunica intima, followed by the middle layer, the tunica media, and the outer layer, the tunica adventitia.
Smooth muscle and elastic connective tissue make up the tunica media. When it comes to the upkeep of blood pressure, this layer is the most important of the three. As blood is forced out of the heart, the elastic fibers in this layer can withstand the strain applied to the blood artery. The elastic fibers apply the force back onto the blood when the heart relaxes, keeping blood pressure and flow during diastole.
