The expression of flower color -qualitative character- and the length of the pollen grains -quantitative continuous character- is controlled by genes. Option A) TRUE.
How are characters expressed?Characters might be either qualitative or quantitative, discrete or continuous. In any case, genes are the units that control the expression of these characters.
A gene might be diallelic or multiallelic, and a character might be coded either by a single gene or by multiple genes.
The expression of the individual's phenotype varies according to the interaction between the involved genes and the inheritance pattern.
So characters are genetically determined. However, we need to consider that phenotype is also influenced by the environment.
Individuals are exposed to different environmental pressures that might lead them to express a different phenotype.
The phenotype depends on the interaction between the genotype and the environment. The environment, for instance, has a significant influence on the expression of quantitative characters like the length of the pollen grain.
In the exposed example,
flower color is a qualitative characterthe length of the flowers pollen grains is a quantitative continuous character
Both of them are coded by genotypes. This is, their expression depends on the involved genes. However, in the case of lengths, the environment also plays a significant role in its expression.
Option A is correct. The statement is TRUE.

8. Extend your thinking: Hydrolysis of the carbohydrates you eat begins in your mouth as you chew. How do you think this process might be affected if a person’s salivary glands were unable to produce saliva, which is mostly composed of water?
Answer:
Slow down the break down of carbohydrate.
Explanation:
Hydrolysis of the carbohydrates will be affected if a person’s salivary glands were unable to produce saliva because saliva has enzyme that speed up the digestion rate of carbohydrates. If the saliva did not produced by the organism's salivary glands, the hydrolysis or break down of the carbohydrates did not occur in the mouth and as a result the body takes more time for the complete decomposition or break down of carbohydrates.

In a study published in the journal Nature, scientists studied eight ponds in Florida: four that were populated by a species of fish and four that were not. As they studied the ponds, they noted that the areas around the four fish-populated ponds showed decreased populations of dragonflies and dragonfly larvae, whereas the four without fish showed abnormally large populations of dragonflies and larvae. Dragonflies feed on bees, butterflies, and other pollinators.
Required:
Predict what would happen to the rate of pollination of flowers in a field next to a pond with no tish.
Answer: the rate of pollination of flower, in a field next to a pond with no fish, will DECREASE.
Explanation:
POLLINATION is defined as the process by which flowering plants, through the aid of external agents such as insects,wind, water and other animals, are able to transfer pollen grains from an anther to a receptive stigma. Insects are the most common pollinators. They visit flowers to obtain nectar and pollen as source of food. Flowers use various features, such as colour and scent, to attract and guide insects to the food source within them. In the process of reaching their source of food, insects bring about pollination.
From the study conducted by scientist in Florida, eight(8) ponds where subjected to the the study. The first four (4) ponds had species of fishes that fed on dragonflies and dragonfly larvae, hence the reason for a decrease in the population of the dragon flies in the area around it. While the remaining four (4) ponds had NO fish and the area around it is populated with dragonflies and dragonfly larvae. This is so because of the absence of fish.
It was then noted that the dragon lies fed of the insect pollinators such as the bees and butterflies. Since these dragonflies and its larvae are abundant in the field which is close to the pond with no fish, they will grossly depend on the insect pollinators as their source of food thereby decreasing the rate of pollination in the field next to the pond with no fish.
What do you notice about the products of cellular respiration compared to the reactants of photosynthesis
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Purpose
In this assignment, you will use, evaluate, and improve a simulation to highlight human impact on coral
reef ecosystems. Then you will propose and evaluate real-world solutions to reduce the negative effects
of human activity on this ecosystem and its biodiversity.
Answer:
Explanation:
A coral reef is an environment in which various abiotic (water, sunlight, temperature, salt, waves, and so on) and biotic (aquatic plants, shrimps, fish, corals, and so on) factors combine to maintain the system's homeostasis. A simulation model is a descriptive model that makes future inferences about one system using existing data (or process). A computer-based experiment in which each part of the device contributes to the measurement of the impacts induced by the interaction of unknown inputs is also known as a simulation model. It is possible to determine how changes in water temperature influence the relationship between various types of trophic levels in the coral reef environment, which may be expressed by aquatic plants and fish species, by using a simulation model.
Corals, algae, and fish in coral reefs have a lower survival rate as the pH of the ocean water drops. In acidic ocean water, coral reefs struggle to survive. This is due to the coral's calcium carbonate shell's inability to withstand an acidic environment. Snails, clams, algae, fish, and other animals have calcium carbonate in their skeletons. The death of these animals is caused by increased acidity. As a result, the lower the pH of ocean water, the higher its acidity, and therefore the lower the chance of corals, algae, and fish surviving in the coral reef.
The amount of calcium carbonate in coral reef water is affected by a lower pH value (more acidic). Since coral skeletons are made of calcium carbonate, this has an effect on them. It may be a major issue (since coral reefs are a source of food and tourism), since it would be more difficult for them to calcify or even dissolve. As a result, if 'ocean acidification' occurs as a result of carbon dioxide absorption from the atmosphere, reduced pH may reduce coral reef biodiversity.
The simulation's pH is too low to allow coral reefs to develop. The ocean is affected, and these coral reefs are important for the diversity of marine life because they have a lot of nutrients, which is ideal for small organisms to live in. As a result, if there is a lot of acid in the water, these coral reefs will dissolve and vanish.
I'd raise the ocean's temperature and lower the pH percentage so that users can see how human activity affects the ocean. Human activity causes contamination of the air, which causes CO2, which causes more of the CO2 to be consumed by the seas, raising acidity, which contributes to an increase in temperature and the dissolution of coral reefs.
Add mutations, edit genes, pick factors such as wolves, food, climate (arctic or dessert), and monitor population or pedigree chart were some of the variables I had control over in the simulation.
The impact on the pH of Earth’s oceans can be reduced by lowering the carbon dioxide in the air, and reducing the plastics that goes into the oceans.

Be sure to answer all parts. The net reproductive rate, R0, of a population can be used to predict whether a population will grow or shrink over time. If R0 is greater than 1 then a population is growing; if it is less than 1, the population is shrinking; and if it is equal to one, then the population is at equilibrium. The size of the next generation (Nt 1) of a population can be determined by multiplying the net reproductive rate by the current population size, N. Part 1 out of 2 Given a current population size of 788 and a net reproductive rate of 1.00, what would be the size of the population in the next generation
Answer:
N (t) = 788 individuals
Explanation:
There are some parameters to consider when analyzing the evolution of a population in time regarding its size. Some of them are the generational time -T-, the intrinsic growth rate per capita -r₀-, the net reproductive rate -R₀-, the reproductive value -V₀-. among others.
To obtain the net reproductive rate -R₀- of a population, we must relate the contribution of individuals of each age to the next generation, with the possibility that those individuals reach that age.
It can also be considered the media of female offspring that each female can produce throughout its whole life.
You can also think about it as a quantity by which the population abundance will increase, decrease, or remain the same in the followings generations. And this concept is related to what is stated in the problem.
If R₀>1 ⇒ the population size increasesIf R₀<1 ⇒ the population size decreases If R₀=1 ⇒ the population is in equilibrium. Its size remains the same.According to the given information, we can use different formulas to calculate R₀
R₀ = N(t) / N(0) ------> (N0 being the population size at time zero, and Nt in a
certain generation)
R₀ = sum (lx * mx)---> (Lx being the survival rate and mx the fertility rate)
-------------------------------------------------------------------------------------------------------
To answer this question, instead of calculating the R₀ value, we need to calculate Nt, which is the population size at t generation. In this example, is the following generation, so t=1.
We already know that N₀ = 788 individuals and that R₀=1.
By clearing the equation R₀ = N(t) / N(0), we can get the Nt value.
N (t) = N₀ x R₀
N(t) = 788 x 1
N(t) = 788 individuals
The population size at time 0 and time 1 is the same. This is because the R₀ value = 1, meaning that the population is in equilibrium. It does not increase either decrease. Probably there are as many deaths as births.

Describe the type of community interaction occurring in each of the following cases.
a. A buffalo eats some grass
b. A sea anemone is a marine organism that feeds on fish. It captures its prey using stinging cells. The clownfish (made famous in the movie Finding Nemo) is immune to the stinging cells and can therefore hide from predators inside the sea anemone. When the clownfish urinates, it provides nitrogen (a necessary nutrient) to the sea anemone.
Answer:
1. Predator-Prey
2. Mutualism
Explanation:
The cow consumes the grass. The cow is the predator and the grass is the prey.
The clownfish gets protection from the anemone and in return, the urine of the fish benefits the anemone. Both organisms get the benefit so it’s mutualism.

______ can amplify the effects of temperature by increasing the rate of heat loss by convection.
Answer:
wind
Explanation:
As the air heats up and becomes less dense, it rises higher into the atmosphere, thereby cooler air takes its place and produces wind (moving air is wind). This wind can produce a positive feedback loop that increases the transfer of heat by both evaporation (i.e., by losing heat through the conversion of water to vapor) and convection (i.e., through the movement of air). In consequence, wind created by temperature fluctuation can amplify the effects of temperature. In organisms, winds can also contribute to water loss by increasing the evaporation/transpiration rate.

C. Each cell needs to receive a complete copy of the chromosomes in order for the cell to work
properly
yes
Answer:
C. Each cell needs to receive a complete copy of the chromosomes in order for the cell to work properly
Explanation:
The model in this question depicts the process of DNA replication, which is the process whereby an identical copy of DNA is made. Based on the model in the question, one (1) individual chromosome forms two (2) sister chromatids per chromosome. Each sister chromatid contains the replicated DNA.
This process is very important and must occur prior to any cell division because every cell needs to receive a complete copy of the chromosomes in order for the cell to work properly. For example, each human cell must receive 23 pairs of chromosome or 46 chromosomes in order to function well and this is ensured by DNA replication.
