In pea plants the trait for tall height is dominant over the trait for dwarf height. Which letter should be used to represent the genotype for plant height?
D
F
L
T
Answer:
The correct answer is - T.
Explanation:
Normally, the representation of the trait in the genotype of inheritance pattern is the first letter of the dominant character of the particular trait. In this case, the trait of the height of the pea plant is tall and dwarf.
Tall plants are dominant over the dwarf plant, therefore, the letter T would be used to represent the genotype for the height of pea plant, the small letter of the particular letter would be used to represent the alternate allele of the trait.

The processes involved with reproduction and nurturing a growing zygote
require energy use beyond normal maintenance. What is the best way certain
organisms reduce the energy costs of reproduction?
A. The parents each take turns nurturing the offspring.
B. They reproduce asexually.
C. They have multiple offspring in one pregnancy.
D. They reduce their gestation period.
Answer:
B. They reproduce asexually.
Explanation:
Asexual reproduction often known as abiogenetic multiplication requires just one parent organism and results in hereditary identical progeny (similar to a new copy). Since there is no blending of genetic data required and organisms don't have to invest energy finding a mate, populaces can increment quickly because of asexual generation. Thus, with the guide of asexual generation, the energy needed in the process associated with multiplication and nurturing is diminished contrasted with sexual reproduction.

Type of democracy where citizens elect leaders to represent them in government dictatorship representative democracy oligarchy anarchy
Answer:
representative democracy
Explanation:
Democracy can be defined as a government of the people, by the people and for the people.
There are two (2) main types of democracy and these include;
I. Representative democracy: it's also known as indirect democracy and can be defined as a form of government which typically involves the process of having the citizens of a particular country vote to elect representatives (political leaders) to enact laws, create policies and make decisions on their behalf.
Hence, representative democracy is a type of democracy where citizens elect leaders to represent them in government.
II. Direct democracy: it can be defined as a process which typically involves the candidates voting for their preferred choice. Thus, their choices are reflected directly on the subject matter.
Generally, the type of government in which legislators such as senators or house of representative members are found is known as a democracy and they are saddled with the responsibility of enacting or making laws.

When S strain bacteria were killed by being heated to 60C, then mixed with live strain bacteria and injected into mice, a greater % of
mice died than when the strain bacteria were heated to 100C. Can you propose an explanation for these observations?
Answer:
Due to live strain bacteria.
Explanation:
The first method cause more damage to the mice as compared to the second method because in the first method the killed bacteria were mixed with the live strain bacteria. This live strain bacteria causes diseases in the mice and eventually killed the mice while on the other hand, all the bacteria were killed due to very high temperature so that's why first method causes more damage than second one.

Which characteristic do all protists have?
They all make or consume food.
They all survive in any environment.
They are all unicellular.
They all have flagella.
Answer: They all survive in any environment.
Explanation: Protists have the ability to survive in any environment, even extreme environment. They can live in the ocean, desert or extremely hot environment, or even a extremely cold environment.
I'll explain why the others aren't correct.
Protists can be both unicellular and multicellular, they're not always unicellular. Kingdom Protista contains all eukaryotics, so they're not always unicelluar.
Protist cannot make or consume food. Animals consume food, and plants make food, not protista. Yes they're many plant-like protists out there, such as algae, they get their food from the sun above. So all protists cannot make or consume food.
Protist does have flagella, but not all protists. Protists that are motile and generate movement have flagella, meaning they move. Not all protist move, like plants can't move. So, not all protists have flagella, meaning they can move.
Let me know if you have any questions.

Describe the pressure changes that occur in the lungs during breathing for someone with emphysema
Answer:
Emphysema can lead to destruction of the alveoli, the tiny air sacs that allow oxygen to get into the blood. Their destruction leads to the formation of large air pockets in the lung called bullae. These bullae do not exchange oxygen and carbon dioxide like normal lung tissue. Also, the bullae can become very large.
