In an organism, X, it is found to be impossible to generate loss-of-function mutants for most genes. There is an alternative method of introducing random mutations that can later be screened for the gene(s) in question. This can be accomplished by using insertions due to what genetic entities?
Answer:
Transposable elements (TE)
Explanation:
A transposon, also known as 'jumping genes', is a particular sequence of DNA that can relocate inside of the genome. It affects the genetic identity and can be made use of to either reverse a mutation or create one - it duplicates that genetic sequence. Retrotransposons is a class of TE found in viruses.

Why do plants produce more carbon dioxide than oxygen during the night?
A. Respiration can only occur when there is no available sunlight.
Ο Ο Ο
B. Photosynthesis only produces carbon dioxide during the night.
C. Respiration can happen without sunlight, but photosynthesis
cannot.
D. Respiration produces oxygen during the day and carbon dioxide at
night
SUBMIT
Answer:
C. Respiration can happen without sunlight, but photosynthesis
cannot.
Explanation:
Respiration is the metabolic process by which the cells of living organisms, plants inclusive, obtain energy. Photosynthesis, on the other hand, is the process whereby plant cells synthesize their food in form of sugars (glucose).
Photosynthesis takes place in two stages namely: light dependent stage and light independent stage. The light dependent stage occurs strictly in the presence of sunlight, where oxygen gas is released as a product. Hence, it can only occurs during the day. Respiration, which breaks down the sugar product of photosynthesis to produce energy, occurs at anytime (day or night). Carbon dioxide (CO2) gas is released as a product.
Since the light dependent stage of photosynthesis cannot occur without sunlight, it cannot occur at night. this means that oxygen gas will not be released at night. However, respiration which occurs during daytime and nighttime continually releases carbon dioxide gas. This accounts for the reason CO2 gas is produced more by plants than oxygen at night.
Answer:
c
Explanation:
a) Name the structures that: i) Carry water and mineral salts to the leaf ii) Prevents too much water loss from the upper surface of the leaf iii) Opens to allow gases to pass into and out of the leaf iv) Is the site for most of the photosynthesis taking place v) Is the layer where light is able to pass through directly b) How does a leaf protect itself from unwanted intruders like bacteria from getting in and stopping important reactants from going out? PLEASE ANSWERR
Answer:
a) i) Xylem
ii) Upper epidermis
iii) Stoma
iv) Chroloplast
v) Palisade cell layer
b) By a waxy layer on the cuticle of the leaf
Explanation:
The plant's leaves have a large surface area that is capable of absorbing sunlight. The plant's waxy layer in the surface of the leaf protects it from the loss of water, as well as of diseases caused by the entry of microorganisms. The palisade cell's surface is a single layer of cells underneath the upper epidermis that is adapted to absorb light energy.
The waxy layer is a primary physical barrier composed of insoluble polymers and lipids whose function is to protect the leaves against the entry of harmful organisms including virus, bacteria and fungus. Moreover, the plant's waxy cuticle is also a barrier that prevents the loss of water and solutes.

b. nephron loop dilutes the concentration of solutes in the tubular fluid at its hairpin turn.
c. vasa recta secretes multiple amounts of metabolic wastes against their concentration gradient.
d. vasa recta becomes more concentrated with nitrogenous wastes than the urine.
Answer: Option A.
nephron loop multiplies the concentration of salts in the interstitial fluid of the kidney medulla.
Explanation:
countercurrent multiplier is a system that utilize energy that create osmotic gradients and enable reabsorption of water thereby increase concentration of urine. The countercurrent multiplier uses electrolyte pumps there by making the nephron loop increase the concentration of salts in the interstitial fluid of the kidney medulla because it allows the nephron to reabsorb alot of water and and increase the concentration of urine for excretion while at the same time using as little energy as possible.
A researcher interested in the disappearance of fallen leaves in a deciduous forest carried out a field experiment that lasted nearly a year. She collected all the leaves from 100 plots scattered throughout the forest. She measured the amount of leaves present in November, May and August. The percentages reflect the number of leaves found, using the November values as 100 percent.
Answer:
Elm: 50 %; 1 %
Hazel: 69 %; 4 %
Explanation:
Assume the table looked like this.
[tex]\begin{array}{crrr}\textbf{Month} & \textbf{Ash} & \textbf{Elm} &\textbf{Hazel}\\\text{Nov} &\text{4271 g}& \text{3481 g} & \text{1723 g}\\ & 100\, \% & 100\, \%&100\, \%\\\text{May} & \text{2431 g} & \text{1739 g} & \text{501 g}\\& 100\, \% & x \, \% &z \, \%\\ \text{Aug} & \text{1376 g} &\text{35 g} & \text{62 g}\\& 100\, \% & y \, \% & w \, \%\\\end{array}[/tex]
To get the percentages for each species for May and August, you divide that month's mass by the November mass and multiply by 100.
[tex]x = \dfrac{\text{1739 g}}{\text{3481 g}} \times 100 \, \% =50 \,\%\\\\y = \dfrac{\text{35 g}}{\text{3481 g}} \times 100 \, \% = 1 \,\%\\\\z = \dfrac{\text{501 g}}{\text{1723 g}} \times 100 \, \% = 69 \,\%\\\\w = \dfrac{\text{62 g}}{\text{1723 g}} \times 100 \, \% = 4 \,\%\\\\[/tex]

A person with the genetic disorder Klinefelter's syndrome has an extra x-chromosome (genotype XXY). What can you predict is the most likely genetic mutation that results in Klinefelter's syndrome?
Answer:
The correct answer is non-disjunction at the time of meiosis.
Explanation:
A disorder, which takes place in males exhibiting an additional X-chromosome and is an outcome of an error in cell differentiation resulting in anomaly known as the Klinefelter's syndrome. Due to non-disjunction the egg or the sperm may acquire an additional X-chromosome. When these unusual cells take part in the genetic makeup of a person, then that individual most probably suffers from the condition termed as Klinefelter's syndrome.
In the majority of the circumstances, the division of the cells takes place generally during the development of the sperm, and at the same time, there may be certain errors at the time of egg development. Generally, the condition is mostly seen in the offspring of women that conceive after the age of 35.

Which of the following is an example of adaptive radiation? One population of squirrels becomes two separate species over a long time. One population of lizards forms 15 separate species over a short time. One species of birds becomes better suited to its environment over time. One species of fish forms when two species of fish begin to breed with each other.
Answer:
B. One population of lizards leads to 15 separate species over a short time.
Explanation:
Adaptive radiation is a process in which organisms diversify rapidly into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges and opens environmental niches.
Adaptive radiation occurs when a single ancestral species diversifies into a variety of different species, each with different adaptations to fit different ecological niches.
When does the adaptive radiation occur ?This often occurs when a group of organisms colonizes a new, relatively unexploited environment, and the different ecological niches available in that environment drive the evolution of different adaptations in different subgroups.
The example of one population of lizards forming 15 separate species over a short time is a classic example of adaptive radiation. In this case, the ancestral population of lizards likely colonized a new area with many different ecological niches.
Over time, different subgroups of lizards evolved adaptations that allowed them to exploit these niches in different ways, leading to the diversification of the group into many different species.

Explanation:
Greenhouse gases are gaseous components that induces greenhouse effect. This means that due to their structural ability to trap heat energy in the atmosphere, they contribute to the global warming effect on the Earth. However, this greenhouse gases are produced in large amounts as a result of the day-to-day anthropogenic activities. The following are the greenhouse gases and how they are produced.
Carbondioxide (CO2)- Carbondioxide is the most common and important greenhouse gas. It is generated via natural processes like respiration but also produced when fossil fuels e.g coal, petroleum etc. are burned.
Fluorinated gases- This is another greenhouse gas caused by activities of man. Fluorinated gases are produced in industries during the production of certain products.
Methane- Methane is a gaseous hydrocarbon and the principal constituent of natural gas. Therefore, the production and transportation of oil and natural gases can lead to the escape of methane into the atmosphere.
Nitrous oxide- Nitrous oxide is an oxide of nitrogen. It is mainly produced via agricultural processes such as nitrification and denitrification or use of fertilizers etc. and also industrial actions.
