Answer 1

Answer:

Water separates polar molecules from each other by forming hydrogen bonds.

Explanation:

A polar molecule is a molecule in which the distribution of electrons between the covalently bonded atoms is not even. This means that one end of the bond is slightly more positively charged, while the other end is slightly more negatively charged.

An example of a polar molecule is a molecule of water (H2O). Substances with similar chemical characteristics dissolve in each other. This means that polar molecules will dissolve in water. The partially negative part of a water molecule will interact with the partially positive part of another polar molecule. This results in the formation of hydrogen bonds, which occur when a hydrogen atom is located between a pair of other atoms that have a high affinity for electrons.

what is the biodiversity score of farmland (maize)?

Answers

Answer:

Required Answer:-

The intensification of agriculture has caused dramatic declines in farmland biodiversity (Carvalheiro et al., 2013; Senapathi et al., 2015). Since the 1990s, agricultural policies have been developed in Europe to mitigate this loss through agri-environmental schemes (AES). One AES is “sown wildflower strips”, the aim of which is to create new ecological infrastructures by sowing attractive wild flowers on arable land (a few % of the cultivated area). These ecological infrastructures fall within our definition of MIMS since they represent a massive introduction of managed species in the landscape.

Marcus is hanging a porch swing on his front porch. The first thing he has to do is attach two springs to the ceiling. Then, he fastens the
swing to the springs so that they can stretch and support the weight of the swing. Which two types of potential energy do the springs have?
A. elastic
B. gravitational
C. kinetic
D. stretched

Answers

The two types of potential energy that the springs have when Marcus hangs the porch swing on his front porch are (A)elastic potential energy and (B)gravitational potential energy.

The elastic potential energy is stored in the springs due to their deformation from their natural state. The gravitational potential energy is stored in the swing due to its height above the ground, which is determined by the position of the springs.

When Marcus attaches the springs to the ceiling, the springs are stretched and deformed from their natural state. As a result, they store elastic potential energy. This energy is proportional to the amount of deformation, which in turn is proportional to the weight of the swing and the distance the springs are stretched.

When Marcus fastens the swing to the springs, the gravitational potential energy of the swing is determined by its height above the ground. The higher the swing is from the ground, the greater its gravitational potential energy. The swing's height is determined by the length of the springs and their position relative to the ceiling

Therefore, the correct answers are A. elastic potential energy and B. gravitational potential energy.

For the initial year of a summer camp, 56 girls and 64 boys enrolled. Each year thereafter, 18 more students enrolled in the camp. Let t be the time (in years) since the camp opened. Part A: Write a function rule for the total number of students enrolled t years after the camp opened.

Answers

Answer:

[tex]f(t)=120+18t[/tex]

Explanation:

We know that for the initial year of a summer camp, 56 girls and 64 boys enrolled.

The total children enrolled for the initial year can be calculated as :

[tex]56+64=120[/tex]

Each year, 18 more students enrolled in the camp.

The variable ''[tex]t[/tex]'' represents the time in years since the camp opened.

The following expression :

[tex]18t[/tex]  

represents the extra children enrolled each year

If we sum, we can obtain the following expression :

[tex]120+18t[/tex]

which is the function [tex]f(t)[/tex] for the total number of students enrolled [tex]t[/tex] years after the camp opened.

The function rule is [tex]f(t)=120+18t[/tex]

For example, when [tex]t=0[/tex] ⇒

[tex]f(0)=120+18(0)=120[/tex]

which is the original amount of enrolled children when the summer camp opened.

When [tex]t=3[/tex] ⇒

[tex]f(3)=120+18(3)=174[/tex]

which is the expected value for the total number of students enrolled 3 years after the camp opened.

If a cell completes the cell cycle, then the resulting cells also complete the cell cycle, how many total cells have been formed?
1. 2

Answers

The answer to this is A. The complementary strands are A-T, T-A, G-C, C-G, and U-A

The complementary strand of DNA that is made during DNA replication if the template/parent strand of DNA reads ATG GGC CAT is TAC CCG GTA. Thus, the correct option for this question is A.

What is DNA replication?

DNA replication may be defined as a type of biological process through which two identical replicas of DNA form from one original DNA molecule. This process makes a copy of the DNA in a cell is made before the cell divides.

When it comes to the complementary strand of DNA, either of the two chains makes up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases.

For example, if Adenine A is present in the parental DNA, then it should be complementarily bounded to the thymine and vice versa. Similarly, if Cytosine is present in the parental strand of DNA, then it should be complementarily bounded by guanine and vice versa.

Therefore, the correct option for this question is A.

Much of the Earth’s biodiversity, however, is in jeopardy due to human consumption and other activities that disturb and even destroy ecosystems. Pollution, climate change, and population growth are all threats to biodiversity. These threats have caused an unprecedented rise in the rate of species extinction. Some scientists estimate that half of all species on Earth will be wiped out within the next century. Conservation efforts are necessary to preserve biodiversity and protect endangered species and their habitats.

Explanation:

The way people use land can affect the levels of nutrients and pollution in soil. Any activity that exposes soil to wind and rain can lead to soil loss. Farming, construction and development, and mining are among the main activities that impact soil resources.Over time, many farming practices lead to the loss of soil.

And as for land ita the same we construct bulidings and dig mines it damages the land. And as land is imporatant for survival of all the of the biosphere we are definntelt responsible for it as well.

Our water resources face a host of serious threats, all of which are caused primarily by human activity. They include sedimentation, pollution, climate change, deforestation, landscape changes, and urban growth. And again it it affects the biodiversity of water preety badly. The marine animals suffer because of our causes.

Biomagnification occurs when the concentration of a pollutant increases from one link in the food chain to another (i.e. polluted fish will contaminate the next consumer and continues up a tropic food web as each level consumes another) and will result in the top predator containing the highest concentration levels. It starts a chain reaction originating from our doings.

pollutants accumlate in bodies of fishes beacuse, they eat unhygienic and non fishFriendly stuffs,it passes on to onother fish.

Humans have come to rely on fossil fuels to power cars and planes, heat homes, and run factories. Doing these things pollutes the air with carbon dioxide. Other greenhouse gases emitted by natural and artificial sources also include methane, nitrous oxide, and fluorinated gases. It leads to destroying of ozone layer in antartica and durther affecting the biodiversity of animals as well as of ourselves.

Biodiversity is the amount of variety of life on Earth. Healthy ecosystems and rich biodiversity: ... Increase ecosystem productivity; each species in an ecosystem has a specific niche—a role to play. Support a larger number of plant species and, therefore, a greater variety of crops. Even if a single animal is cut from the biodiversity( ie. Extinct) the whole of the food chain will collapse

Threats to Biodiversity. The greatest threat leading to the loss of biodiversity is the human race. As our population grows together with our need for food, water, industry, transportation, and home comforts, it takes over natural ecosystems and replaces them with unnatural.

Identify locations of critical wildlife habitat for species at risk and the threats to these areas. Where possible, eliminate threats and maintain natural areas. Leave critical wildlife habitat undisturbed, especially nesting and denning sites. Promote wildlife use by setting up bird and bat houses. And reduce the no of cars and automobiles there are. Avoid usimg of plastic and toxic substances as it causes further harm to biodiversity.

In the its our fault thw animals are close to extinction or alredy extinct. The least we can so is help to conserve and preserve our beautiful and diverse biodiversity.

How do you know that energy and matter are conserved during the process of cellular respiration?

Answers

Answer:

Energy and matter are conserved in cellular respiration because it has identifiable inputs and outputs. These can be modeled with chemical equations.

Food undergoes chemical reactions in organisms to generate new molecules for growth or energy. Therefore, energy and atoms are conserved during cellular respiration.

What is conservation of energy and matter in cellular respiration?

The law of conservation of energy states that energy cannot be created or destroyed but can be changed from one form to another. The law of conservation of matter states that the total mass within a closed system that does not allow matter or energy to escape should remain constant. However, the law of conservation of energy states that energy can change from one form to another.

The process of cellular respiration is an example of a chemical reaction, which involves the transformation of one type of matter into another. A chemical equation describes this change in molecular structure. This is the cellular respiration chemical equation:

[tex]C_{6} H_{12} O_{6} + 6 O_{2} = > 6CO_{2} + 6H{2}0 + energy[/tex]

(Glucose + Oxygen yields Carbon Dioxide + Water + Energy)

Therefore, the amount of carbon dioxide atoms released by respiration is the same as the amount of  atoms in the oxygen and carbon that were changed.
