answer 1:
Environmental Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal, and light
Air Pollution
Water Pollution
Soil pollution
Noise pollution
Radioactive pollution
Light pollution
Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil
Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result.
Effects:
Nutrient pollution can cause toxic algal blooms in drinking water sources that create toxins that kill fish and other aquatic animals. Direct exposure to this toxic alga causes serious health problems in humans including neurological effects, respiratory problems, stomach and liver illness, and rashes.
answer 2:
The Industrial Revolution brought rapid urbanization or the movement of people to cities. Changes in farming, soaring population growth, and an ever-increasing demand for workers led masses of people to migrate from farms to cities. Almost overnight, small towns around coal or iron mines mushroomed into cities.

Suppose a disease wipes out most of the mountain Lion population in the food web shown
If mountain lions were to disappear from a food web, their prey populations could potentially increase, which could then lead to changes in the populations of the prey's food sources.
For example, if mountain lions primarily preyed on deer, a decrease in the mountain lion population could lead to an increase in deer populations, which could then result in overgrazing of vegetation in the area. This could then impact other species that rely on that vegetation, such as small mammals and birds.
Overall, the loss of a key species like the mountain lion can have significant impacts on the food web and ecosystem as a whole. It is important to understand and mitigate these impacts in order to promote the long-term health and sustainability of the ecosystem.

A meteor moves into Earth's atmosphere at a speed of 35.00 km/s. It is slowed by friction with Earth's atmosphere by 0.02 km/s before it reaches Earth's surface. What is the final speed of the meteor?
Answer: 34.98
Explanation: So basically the meteor was falling at 35.00 km/s and slowed down by 0.02. 35 - 0.02 = 34.98. Period.
The final speed of the meteor 34.98 because it is slowed down due to friction of earth atmosphere which is act opposite direction in compare to meteor movement, So the net velocity of meteor becomes 35.00-0.02 which is equal to 34.98 km/sec.
What is motion map?Motion maps are define as one-dimensional plots built off of a position line.
All motion map contain a position line and dots which denote the objects position at a particular time interval. Motion maps should also have vector arrows to indicate an object speed and direction which is known as velocity.
Motion maps can be a though of as a strove photographs which has many images on one picture. There is set time interval between each image. The value of time step can be different for different motion maps.
Kinetic energy is a form of energy it possess when any object or person is in motion . It can be defined as the work needed to be done to produce a motion in a object from rest position.
If we want to acceleration in an object then we must apply a force on a object to give motion so we can say that we required to do work for acceleration and then we can say that required is equal to kinetic energy.
Therefore, the final speed of the meteor 34.98.

Starting with the sand, Mara adds water to the jar one tablespoon at a time. Water soaks the sample from the bottom up. She counts the number of tablespoons of water it takes to bring the water level up to the top of the sample. She repeats this process for the gravel and soil samples.
3 jars: one with sand and water, one with gravel and water, one with soil and water
Mara adds 4 tablespoons of water to the sand, 7 tablespoons to the gravel, and 5 tablespoons to the soil.
Calculate the porosity of each of Mara's samples using this formula, and record the results in the chart.
% porosity = (amount of water added to sample ÷ total sample volume) × 100
“Total sample volume” is the amount of soil, sand, or gravel. A half cup is equal to 8 tablespoons.
Answer: 50, 87.5, 62.5
Explanation:
4/8=0.5x100=50
7/8=0.875x100=87.5
5/8=0.625x100=62.5
The porosity of each of Mara's samples using this formula, and record the results in the chart are 50, 87.5 and 62.5
What is porosity?Porosity is defined as a measurement of the vacant spaces in a material; ranges from 0 to 1, or as a percentage from 0% to 100%, depending on how much of the substance's volume is made up of voids. The volumetric fraction of pores in a material is known as porosity. These pores may be found in the internal or external structure of the object.
The formula used to calculate porosity is
% porosity = (amount of water added to sample ÷ total sample volume) × 100
4/8 = 0.5 x 100
= 50
7/8 = 0.875 x 100
= 87.5
5/8 = 0.625 x 100
= 62.5
Thus, the porosity of each of Mara's samples using this formula, and record the results in the chart are 50, 87.5 and 62.5.

Which of the following will NOT result in the expression of the dominant trait? Two dominant factors (alleles) One dominant and one recessive factor (allele) Two recessive factors (alleles) All of these result in the expression of the dominant trait
Answer: C. Two recessive alleles
Explanation: i took the test
Two recessive factors (alleles) will not result in the expression of the dominant trait. So, the correct option is C.
What is Dominant trait?Dominant refers to the inheritance of qualities that are often carried vertically from parent to kid, when both the parent and the child are impacted by the trait or disorder linked to that gene.
One copy of an allele, which might come from just one parent, is called a dominant allele and results in a dominant phenotype in individuals. Having two copies of a recessive allele, one from each parent, is necessary for a recessive phenotype to develop.
A dominant trait is indeed an inherent characteristic that manifests in a child if it is passed down from one parent to another through a dominant allele. Traits, commonly referred to as phenotypes, can include characteristics like eye colour, hair colour, immunity or susceptibility to specific diseases, as well as physical characteristics like freckles and dimples on the face.
Therefore, the correct option is C.

Using the drop down, complete the first column of the Punnett Square.
(its the same for the t one )
Answer:
tt
Explanation:
The answer would be TT,TT,Tt and Tt. Based on the genotype of the parents, a Punnett square is a figure that is used to forecast the likelihood of inheriting specific traits or genetic features. The approach was created in the early 20th century by an English geneticist by the name of Reginald Punnett, thus its name.
What is the place for the genotype ?The genotype of the parent organisms is written along the top and left sides of a straightforward square grid that is divided into four equal sections. This is known as a Punnett square. The various genetic combinations of the progeny are represented by the squares on the grid.
You must first ascertain the genotype of the parent organisms in order to utilise a Punnett square. The genotype is a term used to describe an organism's genetic make-up and is made up of two alleles, one from each parent.
The dominant and recessive alleles are denoted by uppercase letters and lowercase letters, respectively, for each allele. The gene for brown eyes, for instance, is dominant and is symbolised by the letter "B," whereas the allele for blue eyes is recessive and is symbolised by the letter "b."
The Punnett square may be used to forecast the likelihood that specific traits will be inherited by the offspring of the parent organisms once the genotype of the parent organisms has been established. Each box in the grid indicates a potential allele combination that the progeny might inherit.
Based on the genotype of the parent, you may examine the Punnett square to ascertain the likelihood that the offspring will acquire a certain trait or genetic feature.
