Billy's phenotype is his physical appearance. The phenotype is the physical expression of what the gene is made up of.
Billy is polydactyly i.e he has 6 fingers this is his physical expression also known as phenotype and his genotype will be heterozygous dominant(Tt) for the gene to have express itself in the phenotype of billy. He is heterozygous of the gene because his father is recessive of the gene polydactyly
Which is a disaccharide?
Answer:
Disaccharidases are glycoside hydrolases, enzymes that break down certain types of sugars called disaccharides into simpler sugars called monosaccharides. In the human body.
Explanation:
Disaccharide, also called double sugar, any substance that is composed of two molecules of simple sugars (monosaccharides) linked to each other. ... The three major disaccharides are sucrose, lactose, and maltose.
Three common disaccharides:
#sucrose — common table sugar = glucose + fructose.
#lactose — major sugar in milk = glucose + galactose.
#maltose — product of starch digestion = glucose + glucose.
A disaccharide is a sugar that can be created when two monosaccharides are linked together with glycosydic. Disaccharides are soluble in water and a few examples of this are; maltose, sucrose, and lactose. Finally, they’re also one of four chemical linkings for carbohydrates.

A rat population has an average weight gain between weeks 2 and 4 of 10 grams, and the narrow-sense heritability of the weight gain between 2 and 4 weeks is 25%. What average weight gain would be expected among the offspring of parents whose average gain was 15 grams?
Answer:
The correct answer is - 11.25
Explanation:
Given:
Average weight gain between weeks 2 and 4 = 10 grams
The narrow-sense heritability of the weight gain between 2 and 4 weeks
= 25%
Then
Average weight gain would be expected among the offspring of parents whose average gain was 15 grams-
by the formula:
Average weight gain between weeks + (h) (Average weight gain between weeks - parents average gain )
= 10 + 0.25 (15-10)
= 10 + 0.25 (5)
= 10 + 1.25
= 11.25
Thus, the correct answer is - 11.25

difference between plant and animal Glycolysis
Answer:
no difference
Explanation:
There is no difference between plant and animal glycolysis. Glycolysis is an important step of respiration and refers to the break down of glucose molecule for the generation of energy in the form of ATP. Both plant and animal glycolysis occurs in the cytoplasm of the cell where glucose molecule is broken down and produces 2 molecules of pyruvate and 2 molecule of ATP. This process occurs without the use of oxygen molecule.

In the active site of the enzyme lotzase, a mutation of lysine 132 toaspartic acid causes a loss of lotzase function. Lotzase is most catalytically active at pH 7. Which is the following is the best reason why this might occur?
a. a negative charge is needed for substrate binding.
b. a positive charge is needed for substrate binding.
c. a general acid is needed for catalysis to occur.
d. more than one of the following can be a good reason.
Answer:
B. positive charge is needed for substrate binding
C. a general acid is needed for catalysis to occur
Explanation:
A mutation of lysine 132 toaspartic acid causes a loss of lotzase function as a result of the enzyme lotzase being most catalytically active at pH 7( neutral).
This condition is however achieved under conditions such as a positive charge being involved in the substrate binding and a general acid being involved in the catalytic process.

Bob is struck on the left side of the head with a board and is knocked unconscious. When he recovers consciousness, he can hear but cannot understand what is being said to him. This implies damage to the:________a) Speech center.b) General interpretive area.c) Prefrontal lobe.d) Inner ear.
Answer: Option D.
Damage to inner ear.
Explanation:
Cochlea damage or inner damage causes permanent hearing loss.
It is the inner ear of Bob that is damaged because the inner ear is responsible for changing soundwaves to electrical waves because the inner ear make the brain to hear and understand sounds and therefore keeping balance . So damage to the inner ear causes hearing loss and inability to understand what is heard because the cochlea of the inner that change soundwaves to electrical signals or nerve impulses which allow the brain to hear and understand is damaged.
Some other symptoms of inner ear damage are;
Dizziness or spinning sensation (vertigo)
Nausea and vomiting.
Problems with balance or walking.
Hearing loss (or decrease in sound volume) in one ear.
Earache or ear pain.
Fever (sometimes)
Feeling of fullness in the ear.

In which would you be most likely to find plants and animals that are adapted to survive in extremely cold temperatures
This question is incomplete because part of the content is missing; here is the complete question:
In which biome would you be most likely to find plants and animals that are
adapted to survive in extremely cold temperatures?
A. Desert
B. Savanna
C. Rain forest
D. Tundra
The correct answer is D. Tundra
Explanation:
Tundra biome is one of the coldest biomes on Earth, indeed, the temperature in this biome can be as low -50° C in some zone. At this extremely cold temperature, animals and plants have adaptations to survive in these climatic conditions. For example, animals such as the arctic hare or the polar bear that are found mainly in the tundra biome have thick fur that helps them keep body temperature despite low temperatures in their environment. Thus, the biome in which you would most likely find species adapted to extremely cold temperatures is the Tundra.
In an ecosystem, only 10% of the energy in one trophic level is transferred to the level above it. The rest of the energy is lost to the environment. If the first trophic level (green plants) contains about 250,000 kcal of energy, how much energy is lost when energy is transferred from lizards to snakes?
A.
2,250 kcal
B.
2.25 kcal
C.
225,000 kcal
D.
22.50 kcal
Answer:
B - 2,250 kcal
Explanation:
When transferred from lizards to snakes 2,250 kcal is lost due to only 10% of energy being transfeered to each tropic level, hence option a is correct.
How energy is transferred?
At any given trophic level, only 10% of the energy is transmitted to the next level the remaining 90% is primarily wasted as heat during metabolic activities.
The amount of energy transferred from one trophic level to the next is typically only about 10%, so 2,250 kcal energy is lost when transferred from lizards to snakes.
The number of trophic levels that an ecosystem can maintain, as well as the energy it can store, is constrained by what is known as the 10 percent rule.
Therefore 10% is transferred to the next trophic level, hence 2,250 kcal is lost when transferred from lizards to snakes.

What kind(s) of cells can develop from totipotent stem cells?
O A. Only cells that are identical to the original stem cell
B. Only cells that are closely related to the original stem cell
C. Any cells of the human body, but not cells of the placenta
D. Any cells of the human body or the placenta
Answer:
D.
Explanation:
Totipotent cells can make any of the 220 cell types in an embryo, as well as the cells found in a placenta!
Any cells of the human body or the placenta can develop from totipotent stem cells. Therefore, the correct option is D.
Totipotent stem cells have the unusual ability to differentiate into any type of human body cell, including placental cells. They have the ability to generate all types of cells, including endoderm, mesoderm, and ectoderm, the three basic germ layers. Because of their potential for development, totipotent stem cells can produce both extra-embryonic and embryonic tissues. Although cells produced from totipotent stem cells can differentiate into any cell type, due to maturation and specialization processes, they are not always identical to the original stem cell.
Therefore, the correct option is D.

Among 1,000 gametes produced by a plant of genotype o ci +/+ + p, what types of gametes would be expected, and what number would be expected of each? Assume that the chromosome interference across this region is 80%.
Answer:
Expected gametes : o+ ci+ p+,o- ci- pi-, o+ci- pi+,o- ci+ pi-, o+ci+ pi-, o- ci- pi+
Explanation:
Genetic distance between genes is equal to the recombination frequency, so the total number of recombinant gametes can find out by multiplying the recombination frequency of both sides to the total number of gametes.
Interference= .80;
Coefficient of incidence
= 1 - 0.80
= 0.20
15cM = 15% recombination,
20cM = 20% recombination.
Then, Number of recombinant offspring
= 15 x1000/100
= 150,
Gametes expected= o+ ci+ p+,o- ci- pi-, o+ci- pi+,o- ci+ pi-, o+ci+ pi-, o- ci- pi+
Earth is comprised of four systems, or spheres. Give one example of how a change in one of these spheres of the Earth can affect one or more of the other spheres.
Answer:
Earth is comprised of four circles: the lithosphere, hydrosphere, atmosphere, and biosphere. Changes in any piece of the Earth's framework influences every single other circle.
For example, storms structure in the air which bring precipitation and leads to the rain. Rain influences the hydrosphere by expanding the measure of water in a river, which influence the progression or flow of the stream. flowing rivers change the outside of the lithosphere. Plants and creatures in the biosphere rely upon water to endure.

energy, how should he move the end of the spring?
:::
O side to side, using larger motions
O side to side, using smaller motions
O forward and back along the spring, using larger motions
O forward and back along the spring, using smaller motions
Answer:
O forward and back along the spring, using larger motions
Explanation:
Longitudinal wave that carries more energy, he move the end of the spring by pushing the spring forward and backward directions using larger motion that creates two regions in the spring, the crowded area known as compression and more distance between parts of the spring known as rarefaction. If there is more compression in the spring so there is a lot energy present in the spring. So it is only possible when using larger motions in the spring.

If a population of 100 earthworms is growing at 0.37 per capita per year, how many earthworms will there be after one year? 137 100 37 370
Answer:
The correct answer is - 137 earthworms.
Explanation:
Population growth is loosely characterized as the change in the measure of people of specials in a territory after a particular time frame. Population development is the adjustment in the measure of people of that species after some time.
Population growth = (rate/total number of individual) ×100/t
= (37/100)×100/1
= 37
Then, the total number of individuals after one year
= 100 + 37
=137
