Answer:
Dopamine is a substance produced in the brain and is responsible for controlling our movements. The cells that produce dopamine are located in an area known as the brainstem, from where dopamine is then secreted into the basal ganglia, an area of the brain that plays an important function in regulating our movements.

two ways that people can reduce the impacts of landslides
Answer:
There are also various direct methods of preventing landslides; these include modifying slope geometry, using chemical agents to reinforce slope material, installing structures such as piles and retaining walls, grouting rock joints and fissures, diverting debris pathways, and rerouting surface and underwater drainage.

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.
Answer:
It it not, 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.
Answer:
option 1 is correct
Explanation:
in dispersive, each strand of DNA has alternating fragments of old and new DNA while in the semiconservative each new double helix consists of one old and one new strand.
each of these rod shaped structures has only 1 copy of the DNA
A.chromatids
B.mutation
C. ribosome

Ribosome, I am not sure just a lucky guess! Hope you get it right!!
How many years ago is .3 million years?
How about .02 million years?
Answer:
300 000 Years is .3 years
200 000 Years is .2 years
(hope this helped if ya need more dm me on discord AkashTheMissle07#3880)
Explanation:
0.3 year ago is three hundred thousand year ago and 0.2 year ago is two hundred thousand year ago.
What is year?Every planetary body has an orbital period, it is called as a year. when earth complete its one orbit around sun, we call it a year. Due to earth's axis, we experience seasonal changes throughout a year.
The earths rotation period is approximated into number as calendar. The modern calendar is called as Gregorian calendar represents 365 days of year, or 366 days of a leap year.
To denote period, loosely associated with it, year is used. Most civilized types of calendar used are Gregorian calendar, it uses two notions, to indicate numbering of year, AD is short form of "Anno Domini" (meaning "in the year of the Lord"), and CE is short form of "Common Era".
So basically 0.1 million year refers to 1000 000 year ago, therefore 0.3 year is 3000 000 and 0.2 is 2000 000 years.

Which student identified the correct step and the result of that process?
Frank claims step 1 is DNA replication which produces proteins needed by the organism to grow and develop
Emma claims step 2 is transcription, resulting in a double stranded RNA molecule needed for translation in the nucleus
Francine claims step 3 is translation which produces the mRNA strand by reading and pairing bases to the DNA template
Tyrone claims step 4 is the production of amino acids, which will form proteins, resulting in the expression of genes found in DNA
Answer: Emma claims step 2 is transcription, resulting in a double stranded RNA molecule needed for translation in the nucleus

Give the experiment to show that water is necessary for photosynthesis.
Answer:
Well, just get two plants. Give one plant water and don't give the other any water. Record the results, how the plant with water and the one without survive.
Explanation:
The one without water should die, because photosynthesis is how plants make food and it does need water.

Answer:
Liquid because it's always moving somehow, so the particles have more kinetic energy
how does density-independent limiting factors
can affect populations
Answer:
Density independent limiting factors also cause population sizes to increase. For example, the water from a flash flood increases the growth of vegetation, thereby providing more food for primary consumers in the ecosystem.

What are the differences between white blood cells and normal eukaryotic cells?
Answer:
White blood cells (WBCs) are specialized to respond to antigen and produce antibodies as well as undergo phagocytosis in response to toxic stimuli.
WBCs are part of immune system and there are five different kinds with specialized features.
In order to make a cell model, it is best to use a muscle cell and a nerve cell or neuron: there are pronounced structural differences and those are present throughout animal kingdom.
Lower animals ( such as insects, worms etc. ) have different immune system, however, they do have typical neuron and a muscle cell/skin cell (fibroblast). Such cell models are likely to be easy, distinct and bring you good grades without going through much complication and confusions of various organ systems and animal mod

Selective breeding produces cultivated varieties of plants within the same genus. Cultivars often use ____
names following the genus, which are not based in Latin. For example, for a hybrid tea rose which is
black, it is called Rosa'Black Baccara'.
Answer:
Binomial
Explanation:
Answer:
The correct answer is - cultivar epithet.
Explanation:
Selective breeding results in cultivated varieties of plants of the same genus. These cultivated varieties are called cultivar names. This cultivar name consists of the scientific Latin botanical genus name followed by a name called as cultivar epithet.
Vernacular language is the full cultivar epithet of the species such as an example given here of herbal hybrid tea called Rosa 'Black Baccara'.
Which statement correctly describes the significance of meiosis during gamete formation?
Answer:
Explanation:
During sexual reproduction, meiosis generates genetic variation in offspring because the process randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gamete. The two gametes then randomly fuse to form a new organism.
Why is animal testing bad?
Answer:
Explanation:
Animal experiments may result in clinical trials of biologically faulty or even harmful substances, thereby exposing patients to unnecessary risk and wasting scarce research resources. Animal toxicity studies are poor predictors of toxic effects of drugs in humans.
Answer:
Experimenting with animals is not justified with anything, they practically play with beings that have life, emotions and that feel pain like all living beings.
Advances the experiments that are done on them, are not used, or the purpose is simply lost, as well as their life.

land, and one that flies. Explain how each one moves and how it is uniquely adapted for
movement within its environment.
Answer and Explanation:
Land - Lion
Water - Sealion
Flies - Bees
Lions have strong retractable jaws that help them eat their prey and that way they adapt to their enviroment.
The Sealion's thick, oily fur and a layer of blubber allow them to keep a high temperature in cold waters.
A Bees body carries an electrostatic charge that attracts pollen and that way they can keep it in them.
