Describe the environmental advantages and disadvantages of using hydroelectric power to generate electricity in the UK.
(6 marker)
Answer: Hydropower is generally available as needed; engineers can control the flow of water through the turbines to produce electricity on demand.
Explanation:
Answer:
Impact on Fish. To create a hydro plant, a running water source must be dammed.
Limited Plant Locations. While hydropower is renewable, there are limited places in the world that are suitable for plant construction.
Higher initial Costs.
Carbon and Methane Emissions.
Susceptible to Droughts.
Flood Risk.
explanation:
Hydroelectric power is energy created using the power and movement of flowing or falling water. It currently makes up only around 2.2% of Britain's total electricity supply, but has a long history in the country, having first been harnessed in 1878 to power the lights of Cragside country house in Northumberland. Globally, hydropower accounts for around 17% of all energy production, so should the UK rethink its approach to going green.

The explanation 'mRNA is single-stranded and is involved in transcription' accurately describes the structure of nucleic acid and how it is involved in the process of gene expression.
During gene transcription, a fragment of DNA called gene is used as template to create a complementary messenger RNA (mRNA).Subsequently, this mRNA is then used as template to generate a protein by a process called translation.This mRNA is a single-stranded nucleic acid instead of a double-stranded nucleic acid (like DNA).In conclusion, the explanation 'mRNA is single-stranded and is involved in transcription' accurately describes the structure of nucleic acid and how it is involved in the process of gene expression.

B)
an increase in the number of cars on the road
C)
a decrease in the price of cars
D)
an increase in cars that use gasoline efficiently
Answer:
D
Explanation:
decrease in prices will cause more driving which causes the smog

equation of gaseous exchange in plants
Answer:
See the answer below
Explanation:
Gaseous exchange in plants involves the entering of oxygen and the exit of carbon dioxide in its place. It is an important process that helps sustains the life of plants, just like every other living organism. The oxygen that enters is utilized in the process of respiration during which carbohydrates are broken down to unlock their energy for metabolic activities.
Oxygen usually diffuses-in through the stomata while the carbon dioxide diffuses in the opposite direction. The summary of the gaseous exchange is summarized in the equation below:
Glucose (food) + Oxygen ---------> Carbon dioxide + water + energy
Or better still;
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP[/tex]

(brainliest if right!) How is the dispersive model different from the semiconservative model of DNA replication?
1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
2. In the dispersive model, the old double helix is degraded, and in the semiconservative model half of its nucleotides are used in the construction of two new double helices.
3. In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
4. In the dispersive model, one strand of the new double helix is made of DNA, and in the semiconservative model the other strand is made of RNA.

Explain why polar and ionic R groups are hydrophilic.
Explanation:
They are hydrophobic. About 5 amino acids have polar side chains, R-groups which do not ionize or become positively or negatively charged. These R-groups are neither strongly hydrophilic nor hydrophobic. Atoms in long molecules, such as polypeptides, are not rigidly fixed in space or position

Consider what you know about biotic and abiotic factors in an ecosystem. What is one of the reasons that nutrients in a vegetable patch might be considered abiotic?
Answer:
Nutrients can come from dead plants that have decomposed. Available nutrients affect the carrying capacity of garden plants. Nutrients are mostly obtained from the soil.
One of the reasons that nutrients in a vegetable patch might be considered abiotic is:
The nutrients are gotten from the soil and they are decomposeAccording to the given question, we need to give one reason why the nutrients in a vegetable patch can be considered an abiotic factor.
As a result of this, we can see that the nutrients in a vegetable patch can be considered as an abiotic factor because they are already decomposed.
An abiotic factor in an ecosystem is any non living thing which has a direct (or indirect) impact on the living things in an ecosystem.

Which of the following is the function of nucleic acids?
A. Breakdown chemical compounds
B. Carry heredity information
C. Structural support
D. Short-term energy storage
Answer:
B. Carry heredity information
Explanation:
Nucleic acids are one of the four types of biological molecules in nature. The other three being: proteins, carbohydrates, lipids. Nucleic acids consists of Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA).
DNA is a nucleic acid found in the NUCLEUS of eukaryotic cells or nucleoid region of prokaryotic cells where it functions to store or hold genetic information for the cell. On the other hand, RNA functions to carry the stored information in order to be expressed. Hence, according to this question, the nucleic acid functions to carry heredity information.
