Answer:
he germ cell split in half to create four gametes
Explanation:
Germ cells are the reproductive cells found in the male and female species. They are the cells that are responsible for the formation of the offspring through reproduction.
Germ cell splits two times in half to produce four gametes.
Germ cells undergo meiosis in which one parent splits to produce four gamete cells.Meiosis in the germ cells occurs in two steps called meiosis I and meiosis II.In the first stage of meiosis I, the homologous pairs of the chromosomes separates and at the end daughter cells are produced.In the meiosis II stage, further division occurs and the haploid sets of four gametes are produced.Since the division occurs two times in meiosis four daughter cells that are haploid (n) is produced.Therefore, germ cells divide two times to produce the gamete cells.

what experminental erros do you expect to encounter when developing an experiment involving hot water
Answer:
The correct answer would be - unstable water temperature as heat lost with time.
Explanation:
Heat is a physical property that continuously decreases with time so in any experiment, if hot water is involved it might lose its heat with time so there will be less temperature than the initial of the experiment or when it has been heated.
Heat can be lost to its surrounding or lost by in close contact with other components of the experiment like container.

How do living
things grow?
Answer:
Most living things need oxygen, water and food to grow. ... Other living things eat plants or other animals for food. The cells of living things divide, allowing the living things to grow bigger and to change as they grow. The cells divide to form new cells that are different from the original cells.

Which phrase justifies why the theory of evolution is a theory and not a law?
A)Describes the relationship between an organism and its environment
B)Makes accurate predictions based on only a small amount of empirical evidence
C)Explains diversity based on the principle of natural selection
D)Cannot be modified with the discovery of new evidence
Answer:
I think it is D
Explanation:
Because if new evidence cannot be added to it then it is only based on a small amount of evidence. And if new evidence proves it invalid or wrong then it is just a theory then.
Answer:
A. Describes the relationship between an organism and its environment
Explanation:
Explain how you could use a balloon to show a friend why the universe looks the way it does.
Answer: When scientists talk about the expanding universe, they mean that it has been growing ever since its beginning with the Big Bang.
Explanation: The galaxies outside of our own are moving away from us, and the ones that are farthest away are moving the fastest. This means that no matter what galaxy you happen to be in, all the other galaxies are moving away from you.
However, the galaxies are not moving through space, they are moving in space, because space is also moving. In other words, the universe has no center; everything is moving away from everything else. If you imagine a grid of space with a galaxy every million light years or so, after enough time passes this grid will stretch out so that the galaxies are spread to every two million light years, and so on, possibly into infinity.

Explain the difference between macrostates (external arrangements of particles) and microstates (internal arrangements of particles).
Macrostates and microstates may be defined on the basis of their properties and characteristics. Both are part of any system.
What do you mean by Macrostates?Macrostate may be defined as defined by the macroscopic properties of the system, such as temperature, pressure, volume, etc.
Microstate may be defined as the arrangement of each molecule in the system at a particular instant. It governs the internal arrangement of particles in a system. While macrostate is the possible outcome that governs the external arrangement of particles in the system in a definite way.
Therefore, Macrostates and microstates may be defined on the basis of their properties and characteristics.

All of the following are reasons that Mendel chose the pea plant as a model system for his studies EXCEPT ________.
The group of choices is:
peas have a relatively short generation time
peas produce large numbers of seeds
he could control which parents were involved in mating
peas only reproduce by cross-fertilization
peas have many polymorphic traits
Answer:
The correct answer is - peas only reproduce by cross-fertilization
Explanation:
Pea plants not just produced by cross-pollination but self-pollination is also one of the reproduction methods present in it. Pea plants have many type of characteritics or traits that can be controlled by the researcher in parent plants during the mating process.
The generation is relatively short which helps in the study the pattern of inheritance of the traits up to several generations.
Thus, the correct answer is - peas only reproduce by cross-fertilization
Mendel choose the pea plant for his experiment. The correct option is D. All the reasons given are correct except peas only reproduce by cross-fertilization.
Reason Mendel choose the pea plants:
The generation time of the pea plant is less.They produce large numbers of seeds They have many polymorphic traits.Pea plants also reproduce by the self- pollination.

True
OR
False
Answer:
true
Explanation:
viruses come in many different shapes and sizes, each one is different
Answer:
True
Explanation:
Shapes of viruses are predominantly of two kinds: rods, or filaments, so called because of the linear array of the nucleic acid and the protein subunits; and spheres, which are actually 20-sided (icosahedral) polygons. Most plant viruses are small and are either filaments or polygons, as are many bacterial viruses.
When light is reflected, what determines the angle of reflection?
Answer:
The normal line divides the angle between the incident ray and the reflected ray into two equal angles. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection.
Explanation:
The law of reflection states that θi = θ r, or in other words, the angle of incidence equals the angle of reflection. In fact, reflection of light may occur whenever light travels from a medium of a given refractive index into a medium with a different refractive index.
What determines the angle of reflection is the angle of incidence
When light is reflected on a plane surface the angle of reflection is equal to the angle of incidence i.e. θr = θi .
Angle of reflection ; This is the angle between the reflected ray and the normal ray on a reflecting surface while.
Angle of incidence ; This is the angle between the direction of an oncoming ray ( incident ray ) and the line perpendicular to the reflecting surface.
Hence what determines the angle of reflection is the angle of Incidence

When should we clessify something as not living?
Answer:
A non-living thing is anything that was never alive. In order for something to be classified as living, it must grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt. While many things meet one or more of these criteria, a living thing must meet all of the criteria.

explain the process of how sedimentary rocks form.
Answer:
Sedimentary rocks are formed from the weathering of other rocks, dead organic remains or chemical precipitation.Sedimentary rocks form when mud and sand are deposited in layers on the Earth's surface. The layers are deposited in many environments including oceans, rivers and deserts. These layers of sand and mud are later buried. The weight of overlying layers compresses the mud and sand to form solid rock. Steps:
Sedimentary rocks are the product of :
1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock.
