A weed? % the same as me A fruit fly? % the same as me A mouse? % the same as me A chimpanzee? % the same as me.
Gene is taken into consideration as the essential gadget of DNA. The similarity in DNA sequences of various organisms replicates a not unusual place ancestry, which seems to be shared with the aid of using all organism's gifts on earth.
Human DNA suggests very much less similarity with weeds' (vegetation) DNA, that's around 18%. Thus, vegetation display one-of-a-kind metabolic capabilities from human beings, consisting of photosynthesis.
Human DNA suggests around 26% similarity with yeast (fungus) DNA, as yeasts have a few housework genes, equal to genes found in human beings. For example, genes to uptake strength from sugar breakdown.Human DNA suggests 44 % similarity with fruit fly (insect) DNA. Mammals, consisting of human beings and bugs percentage genes, which might be chargeable for their increase and structures.Human DNA suggests 92 % similarity with the DNA of mice as they each are mammals and a percentage many, not unusual place genes.Human DNA suggests 98 % similarity with the DNA of chimpanzees. That is why chimpanzees are taken into consideration as closest relatives of human beings.What is DNA?
DNA is a coiled structure that has a loop that is twisted and has ciloing.
It also has nucleotides sequence for amino acids.
Therefore is clear that all the percentages of DNA calculated are given above.

below you will sketch the difference between cells that go through mitosis versus meiosis. the focus is on the number of chromosomes, not the specific steps, so you only need to draw the chromosomes in each circle. do this drawing for a fruit cell, whose body cells have 8 chromosomes or 4 homologous pairs.
Mitosis produces two diploid cells (2n). Meiosis produces four haploid cells (n). Mitosis: 2 cells-8 chromosomes. Meiosis: 4 cells-4chromosomes.
What is mitosis?
Mitosis is a cell division process through which a diploid somatic cell (2n), produces two daughter diploid cells (2n). During mitosis, the whole-cell first suffers duplication of its content and then it separates. Mitosis occurs in somatic cells and in germ cells.
What is meiosis?
Meiosis is a cell division process that produces gametes from germ cells. Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n). After DNA replication there are two meiotic phases.
The first one is a reductive phase, in which homologous chromosomes separate. In the second phase, the cell suffers a new, not reductive division.Fruit cells ⇒ 8 chromosomes
After mitosis ⇒ 2 new daughter cells with 8 chromosomes (2n)After meiosis ⇒ 4 new cells with 4 chromosomes (n)You will learn more about mitosis and meiosis at

Which statement accurately describes tectonic plate movement?.
Answer:
Tectonic plate movement is a long-term environmental change
Explanation:
a type of movement in which plates of the earth moves on another. Due to this movement, earthquakes occurs which adversely effected the environment of the earth surface. Due to these tectonic plate movement, eruption of volcano occurs which helps in the formation of new mountains and we know that mountains change the climate. These movements causes long-term environmental change because it changes the environment slowly and takes more time to change it

Human activities that contribute to landslides are removing plants from hillsides eliminates the root structures that anchor soil.
How do trees prevent landslides?Tree roots support soil layers, anchor the soil to bedrock and form buttresses against soil motion. Trees also reduce landslide risk by lowering soil moisture levels, interception, evaporation and transpiration are the primary means.
Thus, removing plants from hillsides eliminates the root structures that anchor soil contributes to landslides.

Which statement most accurately describes the differences between respiration and fermentation? Fermentation uses a single substrate as an electron donor and acceptor while respiration uses different substrates. There is no difference between fermentation and respiration. Fermentation uses oxidative phosphorylation for ATP synthesis, respiration uses substrate-level phosphorylation. Respiration uses NADH as an electron carrier, fermentation does not. Respiration uses a single substrate as an electron donor and acceptor while fermentation uses different substrates.
Answer:
Respiration uses NADH as an electron carrier, fermentation does not
Explanation:
Respiration is the process of chemical reactions, in oxidising food to generate energy.
Fermentation is chemical breakdown of organic substrate, like glucose, by microrganisms like bacteria & yeast.
Difference between them is that : Respiration process uses NADH in oxidative phosphoralytion for ATPs . However, fermentation doesn't include use of NADH in oxidative phosphoralytion for ATPs.

Why as viruses described as particles rather than cells?
Answer: A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid.
Viruses do not have nuclei, organelles, or cytoplasm like cells do, and so they have no way to monitor or create change in their internal environment. A virus is not a living thing. And they cannot do anything on their own until they enter a living cell. Without cells, viruses wouldn't be able to multiply.

Please help quick!! I appreciate an answer!!
By looking at the conditions, the part of the water cycle that we model here is Condensation.
What is the Water cycle?It is a type of biogeochemical cycle that shows the continuous movement of water within the earth in different states.
The activity that is shown above reveals the process of condensation, i.e. the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds. Tea kettle boiling forms the water vapor and its vapor is changed its state in the window to a liquid.
