A pure breeding tall pea plant was crossed to dwarf plant. What will be frequency of dwarf plants in F2?
Tall pea plant was crossed to dwarf plant. The frequency of dwarf plants in F2 will be 0%.
A true breeding pea plant is one that, after self-fertilization, only bears offspring with the same traits. True breeding organisms are those that share the same genes for the desired traits and are genetically comparable. These animals possess homozygous alleles. If the alleles are distinct, only one of the gene's alleles—referred to as the dominant gene—will be expressed. The other allele, referred to as the recessive one, has no effect.According to the given cross:
TT X tt (parents)
Tt Tt Tt Tt (offspring) all tall
Hence the percentage of dwarf individuals is 0.

Vital capacity (VC) Next instruct your subject to breathe several normal breaths, then bend over and exhale maximally. After they have exhaled as much air as possible, ask them to stand upright and inhale as much air as possible. Then, quickly place the mouthpiece to their mouth and exhale as forcibly and as long as possible. Three measurements were taken.
a. Measurement 1: 4,500
b. Measurement 2: 4,570
c. Measurement 3: 4,480
Calculate the average vital capacity (VC). Round to the ne number.
Your lab partners average vital capacity (VC) is type your answer... ml.
My lab partner's average vital capacity is 4850ml
Why we are taking the average Value?The highest amount of air a person may inhale before reaching maximal expiration is known as vital capacity (VC). It is equivalent to the total of the inspiratory, tidal, and expiratory reserve volumes. The ability to absorb oxygen will increase the amount of oxygen delivered to the muscles. This implies that one can exercise longer and with less effort.
• There may be some variation in forceful inspiration and expiration for that reason we are taking the average value.
• Calculation : {(4500+5570+4480) ÷ 3} = {14550÷3 } = 4850ml
So the average value of Vital Capacity of the lab partner is 4850ml.

Antidiuretic hormone (ADH) and aldosterone are
different because
O a) one stimulates cells in the distal
convoluted tubule and the other
stimulates cells in the collecting duct.
O b) one regulates the blood concentration of
sodium, and the other does not.
O c) one regulates the blood concentration of
potassium, and the other does not.
Antidiuretic hormone (ADH) and aldosterone are different in that they stimulate cells in the distal convoluted tubule and the other stimulates cells in the collecting duct.
a) stimulates cells in the distal portion convoluted tubule and the other stimulates collecting duct cells.What is the difference between antidiuretic hormone (ADH) and aldosterone?Another distinguishing point between the two hormones is their place of action. “While aldosterone acts, using a simplified renal physiology, in the ascending region of the Loop of Henle and, with that, ends up causing water reabsorption in the renal tubules, ADH acts in the collecting duct, also promoting water reabsorption.”
With this information, we can conclude that Anti-diuretic hormone helps to control blood pressure by acting on the kidneys and the blood vessels. Its most important role is to conserve the fluid volume.

When blood glucose levels is too high, insulin is secreted and is responsible for increasing the absorption of glucose into the body cells for its own use which decreases the blood glucose level to normal levels. Insulin regulates blood glucose levels.
On the flip side, if blood glucose levels are too low, glucagon is secreted and is responsible for converting stored glycogen into glucose which are then secreted into the blood, thus increasing blood glucose levels.

Why is the cell membrane made of two layers?
Answer:
When cellular membranes form, phospholipids assemble into two layers because of these hydrophilic and hydrophobic properties. The phosphate heads in each layer face the aqueous or watery environment on either side, and the tails hide away from the water between the layers of heads, because they are hydrophobic.
Explanation:
Dinobryon is a species of protozoa that reproduces asexually ?
They have less genetic diversity in their population.
Asexual reproduction and genetic diversitySexual reproduction involves genetic recombination and as such, produces genetically more variable offspring.
This is unlike asexual reproduction. There is no form of genetic recombination whatsoever. All the offspring have the same genomes as the parents.
When a population is genetically diverse, such a population will be able to adapt to changes in their environment more quickly.
A population that has little to no genetic diversity can get wiped out by a little change to the environment.
Thus, asexual reproduction can be advantageous in that reproduction is quicker and consumes less energy. However, it makes the population to be susceptible to elimination by environmental changes.

Which of the following population rates is most affected by the species' gestational period?
Birth
Death
Emigration
Immigration
The correct answer is Birth.
The two elements that raise population size are natality—the number of people who are added to a population over time as a result of reproduction—and immigration—the movement of people into a location. Most births are to folks who are young adults or older. Even at replacement fertility levels (when each woman has approximately an average of two children), there will be more births than deaths if the proportion of young adults to older adults is higher where mortality is highest. Immigration and birth rates lead to population growth. The population shrinks as a result of death rates and emigration. A population that has a negative growth rate is one in which there are more deaths and emigrants than births.

Which two fats are the most preferred sources of energy in the body?
Saturated and unsaturated fats are the two fats are the most preferred sources of energy in the body.
What is fat?The term "fat" can refer to any ester of fatty acids or a mixture of them.These molecules most frequently appear in food or living things.A glycerol backbone and three fatty acid tails make up the two types of components that make up a fat molecule. In contrast to glycerol, which is a small chemical molecule with three hydroxyl (OH) groups, fatty acids are composed of a long hydrocarbon chain coupled to a carboxyl group.The term "saturated fat" refers to a fat that contains only single bonds in its fatty acid chains.Glycerides, a kind of fat, are made of fatty acids, which each contain a long chain of carbon atoms that can be linear or branched, and glycerol, which has a short backbone.Unsaturated fat is a fatty acid that has two carbons that share a double or triple bond and is not entirely saturated with hydrogen atoms.Learn more about fat here:
