How does running affect the human (Homo sapiens) heart rate? And is that affect negative, positive, or insignificant? (Answer Question Below)
What are the Confounding Variables?
Answer: During exercise/running, your heart typically beats faster so that more blood gets out to your body. Your heart can also increase its stroke volume by pumping more forcefully or increasing the amount of blood that fills the left ventricle before it pumps. Generally speaking, your heart beats both faster and stronger to increase cardiac output during exercise. It shows a positive effect. therefore, Physical activity is a confounding factor of the relation between eating frequency and body composition.

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

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 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.

Describe the structure and function of the skin
The skin is the largest organ of the human body. It has three layers: epidermis, dermis, and hypodermis.
The epidermis is the outermost layer. It is composed of keratinocytes, a type of epithelial cell that produces keratin. The compact nature of the epithelial cells of the epidermis makes the skin waterproof. Melanocytes are also found in this layer and produce melanin, or skin pigment. The epidermis function as protection against UV rays.
The dermis is the inner thicker layer that is mostly composed of connective tissue and connected to the epidermis by collagen fibers. The structures found in this layer are the hair follicle, hair root, sebaceous gland, and sweat gland. The dermis function is to excrete excess oils and waste out of the body through the production of sweat and production of vitamin D with specialized cells found in this skin layer.
The hypodermis is the innermost layer that is composed of adipose tissue. It functions as a cushion between the muscles and the skin.
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

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.

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.

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.
