In developing countries with high population rates, at which trophic level do people generally thrive?
In developing countries with high population rates, people generally thrive at a trophic level of 2.2.
Trophic levels are the positions that feed in a food chain or web. The population size diminishes as you move up the trophic levels of an environment.
Numerous consumers consume food at various trophic levels. When people eat plants like vegetables, they are the primary consumers. When they eat cows, they are incidental consumers. When they eat fillets, they are secondary consumers.
Higher trophic levels typically have fewer creatures since there is less energy there. At higher trophic levels, organisms are often greater in size, but because there are fewer of them, there is less biomass produced. The total mass of all trophic-level creatures is known as biomass.

Which of the following is/are not a condition affecting the Hardy-Weinberg equilibrium?Recessive traitsGenetic driftMutationNatural selection
Hardy-Weinberg equilibrium tells that the variation in genetics present in a certain population will remain constant in the absence of any disturbing events from one generation to another. Conditions that are not affecting this principle are natural selection, genetic drift, and mutation. These forces if present in a population will affect the equilibrium which is being maintained by this principle. and will eventually lead to an evolution. Natural selection is present when the organism adapt and change. Genetic drift is present when there are variants forms of genes. Mutation is present when there are permanent changes in the DNA sequence. These processes should be absent in order to mantain the principle of Hardy-Weinberg equilibrium.
Answer - recessive traits

Match the following processes in respiration with their location within a cell.
The following processes in respiration with their location within a cell are: -
A. Proton moves into - Thylakoid Lumen
B. Respiration - Mitochondria
C. C3 Cycle - Stroma
D. PS I and PS II - Thylakoid Membrane
Thylakoid Membrane- The light processes of photosynthesis are carried out by a system of connected internal membranes called thylakoid membranes in a chloroplast. They are organized into stacked & unstacked sections, grana & stroma thylakoids, which are differently enriched with photosystem I & II complexes.
Mitochondria- The mitochondria, membrane-bound cell organelles, generate the majority of a chemical energy needed to power a cell's metabolic processes. The small molecule adenosine triphosphate serves as a reservoir again for chemical energy produced by mitochondria (ATP).

The density of gold is 19, 320 kg/m³ and the density of
mercury is 13, 500 kg/m³. If a cube of gold that measures
0.100 m on each side is placed in a tank of mercury and
weighed while under the surface, what is the apparent weight
of the cube?
The apparent weight of the submerged gold is 57N.
What is apparent weight?According to physics, an object's perceived weight is a characteristic that describes how heavy it is. When the force of gravity acting on an object is not counterbalanced by a force of equal but opposite normality, the apparent weight of the object will differ from the actual weight of the thing.The weight of a passenger on an elevator is one illustration. When the elevator starts to rise, the object starts to apply downward force. If a scale were used, it would be clear that the downward force is making the object heavier and changing its apparent weight.So, the weight of mercury is 13500kg/m³ × (0.1m)³ = 13.5kg = 132.3N.
The initial weight of gold is 19320kg/m³ × (0.1m)³ = 19.35kg = 189.3N.
Then, the apparent weight of submerged gold is:189.3N - 132.3N = 57NTherefore, the apparent weight of the submerged gold is 57N.

The subject is Kudzu An invasive speciesReview the pic Then answer the “•”Give two predictions, in your own words, as said in the photo
Invasive species are those that have been lost to areas outside their original range and that may cause damage in their new range.
. Answer: "Plants of this ecosystem will be affected"
Explanation: invasive species such as Kuduzu can displace native species by competing for resources or habitat, which alters community structure and can result in the extinction of native species.
In the photo we can see that Kuduzu is a trailing plant that takes away the light from the plants that are below and therefore they do not survive.
.Answer: "Negative consequences are produced in the environment, leading to a loss of biodiversity"
Explanation: each species is related to the rest of the living beings. An autotrophic plant will be at the beginning of a food chain and if it is completely extinguished it will affect each link that continues. All living beings that depended on the presence of the plant will be negatively affected, decreasing their number and therefore leading to a loss of biodiversity.

When a blood sample is placed in distilled water for two hours. The blood cells gained water because they were placed in a hypotonic solution. Thus, the correct option for this question is B.
What is a Hypotonic solution?A Hypotonic solution may be defined as a type of solution that possesses a lower osmotic pressure than the solution through which it is compared. This type of solution generally has a lower solute concentration.
Distilled water significantly behaves hypotonic to the red blood cells. Due to this, the red blood cells swell, and red-colored pigment known as hemoglobin leaks from it as a cell increases its size. Due to this, the color of the solution changes into transparent red-pink.
Therefore, when a blood sample is placed in distilled water for two hours. The blood cells gained water because they were placed in a hypotonic solution. Thus, the correct option for this question is B.

Based on what we learned so far from the article, what can you say about the peas we eat or purchase?
Based on the article, the color, length, and taste of peas that we eat or purchase is based on hormones and enzymes that affect the peas' development. If there is a presence of mutation, an enzyme will not be produce making the pea remain as green instead of yellow. Mutation is also the reason behind the taste of peas that are extra sweet because of the different enzyme produced. The length of peas is also based on an enzyme production. If such enzyme is not present, there is a mutation making the peas short.
In watermelons, the genes for green color and for short shape are dominant over their alleles for striped fruit and long shape. Suppose a plant that has genes for long striped fruit is crossed with a plant heterozygous for both these traits. What would be the phenotypic ratio of offspring from this cross?
Based on the genotype of the parents, the phenotypic ratio of the offspring is 1 : 1 : 1 : 1
What is the genotype of the parents of the cross?The genotype refers to the sum total of the genes present in an organism.
The genotype may also refer to the sum total of the genes that an organism has for a particular trait.
The genotype of the parents of the cross of the watermelons is determined as follows:
Let the allele for green be G, and the allele for stripped will be g.
Let the allele for short shape be S, and the allele for long shape will be s
Therefore, the genotype of a plant that has genes for long-striped fruit is ggss, and the genotype of a plant heterozygous for both these traits will be GgSs
The cross will be as follows: ggss x GgSs
The offspring of the cross will be: GgSs, GgSs,GgSs, GgSs, Ggss, Ggss, Ggss, Ggss, ggSs, ggSs, ggSs, ggSs, ggss, ggss, ggss, ggss.
