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.
GgSs = green and short
Ggss = green and long
ggSs = striped and short
ggss = striped and long
The phenotypic ratio is 1 : 1 : 1 : 1

If your digestive system is damaged or fails, how are other body systems or the body as a whole affected?
Body systems must work together. If one system will be damaged or fails, the other systems will be affected. If the digestive system will be fail, digestion will fails. Water will not be absorb that will lead to the circulatory system to have difficulty in the consistency of blood. If there is a presence of digestive disease, there will be an interference in the digestion as well. Other organ functions will be affected, too. Several effects will be seen such as dehydration, poor absorption of nutrients, blocked blood flow, etc. If the digestive shuts down due to damage of muscles or nerves, it may cause nausea, vomiting, lack of appetite and malnutrition. The nervous and circulatory systems work with the digestive system and these systems are greatly affected if it will not work properly.
The respiratory system is affected if the digestive system fails. These two systems work together to provide power to the entire body system. If digestion fail due to overeating, it can cause abdominal bloating. Bloating can lead to shortness of breath.

How does budding produce more yeast?
Budding produces reproductive cells called spores.
Budding splits the DNA of yeasts in two separate cells.
Budding produces egg and sperm cells to create yeast cells.
Budding causes the cells of the yeast to split into two separate yeast cells
Budding produces more yeast by: (2) Budding splits the DNA of yeasts in two separate cells.
Budding is among the forms of asexual reproduction where only one parent is required to give rise to daughter cells and no formation of gametes occurs. In budding, a small projection comes out from the parent body which eventually grows into an adult and separates from the parent body.
Yeasts are the eukaryotic unicellular species. They belong to the kingdom fungi. There are several species of yeasts in existence. The major use of yeasts can be seen in baking and making of alcoholic beverages.

Although animal nervous systems differ in complexity, their nerve cells are still remarkably similar
a. True
b. False
It is true that even though animal nervous systems vary in complexity, their nerve cells are remarkably similar.
Nerve systems exist in nearly all multicellular animals, though their complexity varies greatly. The only multicellular animals without a nervous system are a sponge and the placozoan and mesozoan organisms, both of which look like tiny blobs. With the exception of a few worm species and echinoderms, all other animals have a nervous system that includes a brain, a central cord (or two parallel cords), and nerves that radiate from the brain and central cord. The nervous system of ctenophores (comb jellies) and cnidarians (such as anemones, hydras, corals, and jellyfish) are made up of a diffuse nerve net.
The most fundamental functions of the nervous system are to direct an organism's movement and to influence its environment (such as through pheromones). To accomplish this, signals are sent from one cell to another or from one area of the body to another. The sources of the output that the nervous system produces are signals that travel to muscle cells and cause the activation of muscles, and signals that travel to endocrine cells that cause the release of hormones into the bloodstream or other internal fluids.

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.

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.
