Explanation:
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.
What object allows all light to pass through?

(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.
Does DNA in prokaryotes and eukaryotes use the same nitrogenous base pairs?
Answer:
Ukaryotes consist of membrane bound nucleus whereas prokaryotes lack a membranebound nucleus.
Explanation:
Ukaryotes consist of membrane bound nucleus whereas prokaryotes lack a membranebound nucleus. Prokaryotic DNA is doublestranded and circular. ... The main difference between prokaryotic and eukaryotic DNA is that prokaryotic DNA is found in the cytoplasm whereas eukaryotic DNA is packed into the nucleus of the cell.
No, DNA in prokaryotes and eukaryotes does not use the same nitrogenous base pairs.
What is DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
Moreover, deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.
Therefore, in all living things, DNA is essential for inheritance, coding for proteins, and providing instructions for life and its processes. DNA dictates how a human or animal develops and reproduces, and eventually dies.

2. What is a pedigree?
Answer:
please give brainlestExplanation:

a purebred animal.
2the recorded ancestry, especially upper-class ancestry, of a person or family.
Answer: the origin and the history of something
Explanation:
Pedigrees use a standard set of symbols to make them easier to understand. Males are represented by squares, while females are represented by circles. Parents are connected by horizontal lines, and vertical lines stemming from horizontal lines lead to the symbols for their offspring
1.
The bud shown in the diagram below was produced by asexual reproduction. Which process is responsible for the formation of the bud?
2 Asexual reproduction differs from sexual reproduction in that, in asexual reproduction..
(a) new organisms are usually genetically identical to the parent
(b) the reproductive cycle involves the production of games
(c) nuclei of sex cells fuse to form a zygote
(d) offspring show much genetic variation
Answer: 1. Mitosis
2. Answer A.
Explanation:
Stick insects that reproduce asexually are less biologically diverse because they can't evolve as quickly as species that reproduce sexually can. Thus, option A is correct.
What is role of asexual reproduction in evolution?Asexual reproduction, in contrast to sexual reproduction, only contributes to genetic variety in the population if a chance mutation in the organism's DNA is passed on to the progeny.
Evolution can occur gradually. Asexual creatures often evolve relatively quickly following a dramatic mutation and do not need as many generations to accumulate adaptations as do populations that reproduce sexually.
Asexual reproduction has the benefit of allowing for rapid population growth under the right circumstances. You only require one parent. Since you don't require a partner, it is more time and energy efficient.
Therefore, new organisms are usually genetically identical to the parent.

Answer:
How do your cells know what to do? Just like builders have blueprints to tell them how to build a house, your cells also have instructions. Your cells' instructions are molecules of DNA.
What is DNA?
DNA is the material that makes up our chromosomes and stores our genetic information. When you build a house, you need a blueprint, a set of instructions that tells you how to build. The DNA is like the blueprint for living organisms. The genetic information is a set of instructions that tell your cells what to do.
DNA is an abbreviation for deoxyribonucleic acid. As you may recall, nucleic acids are a type of macromolecule that store information. The deoxyribo part of the name refers to the name of the sugar that is contained in DNA, deoxyribose. DNA may provide the instructions to make up all living things, but it is actually a very simple molecule. DNA is made of a very long chain of nucleotides. In fact, in you, the smallest DNA molecule has well over 20 million nucleotides.
Explanation:
Why are chromosomes so important that they must be precisely and correctly duplicated, sorted, and distributed when one cell divides into two daughter cells?
Answer: It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set.
Explanation:
In mitosis a cell divides to form two identical daughter cells.

Which experiment could the scientists use that would best determine if these tiny structures are spores?
Answer:
The experiment that scientists could use that would best determine if the tiny structures are spores is called Opto-Electronic Imaging and Imaging Processing.
Explanation:
Optoelectronics speaks to the body of knowledge and of electronic devices that source, detect and control light and how they are used or applied. It is founded on the quantum mechanical effects of light on electronic materials.
Besides Optoelectronic Imaging, there are several other techniques that can be used to identify spores. Some of them are:
1. The culture-based methods: These methods involve the growing of spores on an agar plate and on the enumeration of colony units formed therein.
2. Culture-independent methods: These methods are based on
the counting of spores under an electron microscope. This method utilizes the hybridization of DNA for the detection of pores. Opto-electric imaging is preferred and considered more efficient because it is faster than all the above processes that have been mentioned. The above processes have the disadvantage of time-consumption.
