Consider two children with the same two parents. Would you expect them to have the same sets of chromosomes? Explain why or why not.
Answer:
Some of the same
Explanation:
Well, if one is a boy and one is a girl they might look similar but they will have a lot more different chromosomes than if they were both the same genders, but they still wouldn't be exactly the same because everyone, even identical twins have chromosomes differences, even if you cant see them. My final reason is that one sibling might get more genes from one parent than the other.

The government of a flood prone region wants to implement some measure to reduce risk of floods. Which method is likely to reduce the risk of floods in that region
Answer:
The correct answer is "preservation of wetlands".
Explanation:
Wetland are areas of lands that are saturated with water, usually comprised by marshes or swamps. Preservation of wetlands help to reduce the risk of floods because wetlands temporarily store and slow the release of stormwater. It has been reported that areas where wetland have been lost, the chances of flood increases by as much as 80 percent. The government of a flood-prone region would likely reduce the risk of floods by preserving its wetlands.

The difference between Prokaryotic cell and Eukaryotic cell are;
[tex]\begin{array}{lll}&\underline {\text {Prokaryotic}}& \underline {\text {Eukaryotic}}\\ \\ \text {Nuclear \ membrane \ and \ nucleus} & \text {No \ true \ nucleus \ or} & \text {Has \ a \ true \ nucleus} \\& \text {nuclear \ membrane} & \text {nucleoli \ and \ nuclear \ membrane}\\\\ \text {Membrane \ bound \ cell \ organelle} & \text {None &Present} \\\\ \text {Chromosome \ number \ and \ shape} & \text {One} & \text {Several, more \ than \ one} \end{array}[/tex]
Explanation:
Prokaryotic cells
The plasma membranes surround prokaryotic cells, however, within their cytoplasm, there are no organelles bound to the membrane and there is no nucleus in the prokaryotic cell which differentiates it from the eukaryotic cells
Eukaryotic cells
Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell

The midbrain present between the cerebrum and pons.
The nuclei and cerebral tracts are present, where nuclei act as a relay stations for both ascending and descending nerve fibers, mainly involve in auditory and visual reflexes.
Pons is present in front of cerebellum, the nerve fibers make a bridge between the two hemispheres of the cerebellum.
Medulla oblongata is the most interior part of the brain stem, continuous with the spinal cord, the outer portion is called white matter and the central portion have grey matter.

Besides the interaction between animals and plants, what other factors may be involved in the carbon and oxygen cycles?
Answer: .co2
Explanation: co2
The other factors which are involved in the carbon and oxygen cycles are air, ground, respiration, and photosynthesis.
Which factor contributes to the carbon cycle?
Explanation: Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.
How do plants and animals interact with the carbon cycle differently from one another?Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood, and leaves decay bringing the carbon into the ground.

PLS HELP BIG GRADE 5. Water stored in a reservoir is used to generate electricity as it flows down and into a river. The river flows to the ocean, where it evaporates to form clouds. Rain falls from the clouds into streams that flow into the reservoir.
Which location of the water has most potential energy? Assume the amount of water in each place is the same. These are the locations: 1. where it enters the river from the reservoir, 2. when it is in the ocean, 3. when it is in the reservoir, and 4. when it is in the clouds.
1. Where it enters the river from the reservoir.
2. When it is in the ocean.
3. When it is in the reservoir.
4. When it is in the clouds.
Explain your answer.
Answer: Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity.
Explanation: Hydroelectricity can be defined as the generation of electricity by utilizing the speed of water stream in a reservoir of water. The high speed water current is used to move the water turbine the energy produced in the turbine can be used to generate electricity by the generator.
