Answer:
Option A is absolutely correct
Explanation:
The genotype of an organism is its complete set of genetic material. However, the term is often used to refer to a single gene or set of genes, such as the genotype for eye color. The genes partly determine the observable characteristics of an organism, such as hair color, height, etc.
In a broad sense, the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.
Answer:
A. The genetic makeup of an organism

how does Sexual reproduction leads to genetic variation.
Answer:
Sexual reproduction provides genetic diversity because the sperm and egg that are produced contain different combinations of genes than the parent organisms. ... Sexual reproduction involves meiosis, which is the process of a cell doubling its DNA, shuffling its genes, and then dividing the shuffled DNA among four cells.

Answer:
1) The Greenhouse Effect works When the Sun's energy reaches the Earth's atmosphere, Some of it is reflected in space, and the rest is absorbed and re-radiated by the greenhouse gases.
2) The greenhouse effect is the trapping of heat under the atmosphere, which is a natural effect caused by greenhouse gases. However, when greenhouse gas concentrations are too high, they trap too much heat and increase the temperature on Earth, causing the enhanced greenhouse effect.

Sucrose is not a simple sugar because it is made up of both glucose and fructose so sucrose is called a disaccharide. Therefore, option (D) is correct.
What is simple sugar?A monosaccharide, often known as a simple sugar, is a form of carbohydrate that cannot be broken down into smaller molecules of glucose and is thus readily absorbed by the body.
There are three primary kinds of simple sugars: glucose, fructose, and galactose. All of these sugars have the same chemical composition, but their structures are quite different from one another.
Sucrose on the other hand is a disaccharide composed of both glucose and fructose. Therefore, it is not a simple sugar and can be broken down into smaller or simpler molecules.

Which of the following statements about the experiment is true?
a. During the three months, the biomass of animal life was greater than the biomass of plant life.
b. Some of the energy in the system has moved from one organism to another.
c. The air in the glass box contains no carbon dioxide.
d. No energy has entered or left the glass box.
Answer: B. Some of the energy in the system has moved from one organism to another during the three months.
Explanation:
Option A is incorrect as the biomass of plant life will be greater than that of animal life since plants are considered to be primary producers.
Option C is incorrect as the air in the glass box contains carbon dioxide which is necessary to synthesize glucose.
Option D is incorrect as energy has entered the glass box since it's in a sunny location which gives it energy from the sun.
The correct option is B "Some of the energy in the system has moved from one organism to another during the three months".
Complete the chart and classify each organism.
Answer:
On the basis of similarities and differences.
Explanation:
We can classify the organisms on the basis of similarities and differences. There are five kingdoms i.e. Protista, Fungi, Monera, plantae and Animalia. Each kingdom has some unique characteristics so the organisms in the chart will be seen to which kingdom it belongs to see the similarities with them. If the organism is unicellular and eukaryotic organisms so it is placed in kingdom Protista, if the organism is plant like and having chlorophyll so it is placed in kingdom plantae and if the organism has the ability to move from place to place and heterotroph we can place it in kingdom Animalia.

Answer:
Following are the responses to the given question:
Explanation:
Increased [tex]CO_2[/tex] gases in the water may hasten photosynthesis, enabling crops to develop and grow more quickly. Some [tex]CO_2[/tex] is absorbed and more oxygen is expelled as the frequency of rate of photosynthesis.
The higher plants grown means greater water filtration. Natural selection will run its course if the water is less polluted, as well as the fish may not need to pass mostly on full-body plate characteristics to their descendants.
why do prevailing winds and positions of islands cause warm ocean currents to pass Christchurch in normal years
Prevailing winds and positions of islands cause warm ocean currents to pass Christchurch in normal years for the following reasons:
The prevailing winds in the region are generally from the southwest.The position of islands such as New Caledonia and Norfolk Island can also influence the movement of warm ocean currents in the region. In the case of Christchurch, there are a few reasons why warm ocean currents tend to pass by the region in normal years:Warm ocean currents are typically driven by prevailing winds, oceanic currents, and other factors such as the shape of coastlines and the positions of islands.
The prevailing winds in the region are generally from the southwest. These winds blow parallel to the coastline, which means that warm ocean currents are deflected away from the shore and towards the east. As a result, the waters off the coast of Christchurch are generally cooler than those further north or northeast. The position of islands such as New Caledonia and Norfolk Island can also influence the movement of warm ocean currents in the region. These islands help to direct the flow of warm water towards the Coral Sea and the Tasman Sea, rather than towards the coast of New Zealand. This means that Christchurch, which is located on the eastern coast of the South Island, is less likely to experience the effects of warm ocean currents.Note: That oceanic currents and winds can be affected by a range of factors, including El Niño and La Niña events, which can cause changes in sea surface temperatures and alter the path of ocean currents. As a result, there may be some years when warm ocean currents do reach Christchurch, even if this isn't typically the case in normal years.

A breeder is trying to decrease the maturation time in a population of sunflowers. In this population, the mean time to flowering is 100 days. Plants with a mean flowering time of only 90 days were used to produce the next generation. If the narrow-sense heritability for flowering time is 0.2, what will the average time to flowering be in the next generation
Answer:
The next generation average time to flowering will be 98 days.
Explanation:
Before answering the question, we need to know a few concepts.
Artificial selection is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations. Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced. The selection differential, SD, is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,SD = Xs - X₀
Heritability in the narrow-sense, h², is the genetic component measure to which additive genetic variance contributes. The heritability might be used to determine how the population will respond to the selection done, R.h² = R/SD
The response to selection (R) refers to the metric value gained or lost from the cross between the selected parents. R can be calculated by multiplying the heritability h², with the selection differential, SD.R = h²SD
R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),
R = X₀ - X₁
-------------------------------------------------------------------------------------------------------------
Now that we know these concepts and how to calculate them, we can solve the proposed problem.
Available data:
trying to decrease the maturation time in a population of sunflowers.the population mean time to flower is 100 days → X₀Chosen parental Plants mean flowering time is 90 days → Xs the narrow-sense heritability for flowering time is 0.2 → h²According to what we sow previously, we need to find out the value of X₁, which reflects the next generation average time to flowering.
We know that R = X₁ - X₀, so we need to clear this formula to calculate X₁X₁ = R + X₀
We already know that X₀ = 100 days,
Now we need to calculate R.
R = h²SDWe know that h² = 0.2,
Now we need to calculate SD
SD = Xs - X₀Xs = 90 days → Parentals media flowering time
X₀ = 100 → Population media flowering time
SD = Xs - X₀
SD = 90 - 100
SD = - 10 days
Knowing this, we can calculate R
R = h²SDo h² = 0.2
o SD = - 10
R = 0.2 x (-10)
R = - 2
Finally, once we know the R-value we can calculate the X₁ valueX₁ = R + X₀
X₁ = - 2 + 100
X₁ = 98
